Mastering Chaos / Stay Clear Minded!





Mastering chaos can be challenging, but with the right techniques, you can achieve clarity even when life feels overwhelming.

In this engaging 5-minute animated film, we’ll share essential tips on how to stay clear-minded amid chaos. Discover the transformative power of deep breathing to regain your composure, learn to focus on your goals without getting sidetracked, and understand the importance of taking breaks to recharge. This valuable advice will guide you in maintaining productivity while navigating the demands of your busy life. 

Don’t forget to share your thoughts in the comments below! If you find this video helpful, please like and share it with others who might benefit. 



Have you ever felt like you were trying to accomplish so much that your constant multitasking turned into chaos? This is a common problem for people with a lot to do. The best way to combat this overwhelming feeling is to clear your mind so that you are able to focus on achieving your objectives. The following list will help you break through the chaos and bring order to your professional life.
1)
Stop whatever you’re doing, and take a deep breath until you regain composure. This very important action is the first step to relieving that feeling of chaos and is vital to your productivity. Deep breathing affects the nervous system, which in turn relieves feelings of stress and anxiety.Just five to ten seconds of deep breathing, especially while visualizing the source of the stress leaving your body, will allow you to concentrate on the task at hand. In addition to deep breathing, you could even incorporate a soothing phrase or mantra that will signal your mind to calm down and regroup. Your physical body must first be relaxed in order to be productive.
2)
Focus on the goal and don’t become overly detailed. Once you have taken some deep breaths, it’s time to remind yourself what the goal is. What is your overall objective? By keeping the goal in mind, you will be better able to sort through all the details without getting buried in or sidetracked by minute tasks. For example, say your goal is to touch base with a list of clients by making follow-up phone calls. While pulling up your contact list, you notice that you haven’t synced your list on your computer with the one on your smartphone in a while, so you take a detour to complete that task. While that is happening, you also notice that you have some contacts on that list you no longer need, so you begin to update and organize your digital rolodex. All of these other tasks, though they may need completing at some point, are not helping accomplish your overall goal, which is to follow up with your clients via telephone. Keep the goal at the forefront of your mind, and only complete tasks that directly contribute to the completion of that goal.
3)
Take a break and be social. Socializing is a great relaxer and puts you in a positive mindset. It is okay to take a break when you’ve been focused for a long period of time and feel you need to step away for a bit to refresh your body and mind. Text a friend about a lunch date, check in with your spouse about how his or her day is going, or even browse your social networks for five minutes. By taking your mind off the task for a short period of time, you actually can increase your productivity by preventing burnout and excessive stress. Be responsible with your downtime, but don’t be afraid to use it.
Clearing your mind is of utmost importance in the long-term journey of accomplishing your business goals. Remember to take deep breaths, don’t sweat the details, and allow yourself some social interaction. This mix of caring for both your physical and mental needs is crucial to your ability to deal with any level of chaos.

What do you think of our list? Have you tried any of these things? Please share your comments below!

Permaculture / Cultivating Sustainability





Permaculture is a holistic design philosophy that integrates land, resources, people, and the environment in a sustainable and regenerative way. It aims to create self-sufficient agricultural systems modeled on natural ecosystems. 

Here are some key principles of permaculture:

Observe and Interact - By observing natural patterns and interactions, we can design sustainable systems.

Catch and Store Energy - This involves capturing and storing resources when they are abundant for use in times of need.

Obtain a Yield - Ensure that you are getting useful rewards as part of your work.

Apply Self-Regulation and Accept Feedback - We need to discourage inappropriate activity to ensure that systems can continue to function well.

Use and Value Renewable Resources and Services - Make the best use of nature's abundance to reduce our consumptive behavior and dependence on non-renewable resources.

Produce No Waste - By valuing and making use of all the resources available, we minimize waste.

Design from Patterns to Details - Observing patterns in nature and society provides insights for designing efficient systems.

Integrate Rather Than Segregate - By putting the right things in the right place, relationships develop between those things and they support each other.

Use Small and Slow Solutions - Small and slow systems are easier to maintain than big ones, making better use of local resources and producing more sustainable outcomes.

Use and Value Diversity - Diversity reduces vulnerability to a variety of threats and takes advantage of the unique nature of the environment.

Use Edges and Value the Marginal - The most interesting events often occur at the edges, where different environments meet. The interface between things is where the most valuable, diverse, and productive elements often exist.

Creatively Use and Respond to Change - We can have a positive impact on inevitable change by carefully observing and then intervening at the right time.

The Soothing World of ASMR / An Introduction




ASMR, or Autonomous Sensory Meridian Response, is a phenomenon where individuals experience a tingling sensation that typically starts on the scalp and can move down the neck and spine in response to specific auditory, visual, or tactile stimuli. 

Here's an in-depth look:

What is ASMR?
Sensation: Described as a pleasant, calming, tingling feeling, often likened to a "brain massage."

Triggers: These are the stimuli that can induce ASMR. Common triggers include:
Whispering: Soft spoken or whispering voices.

Tapping: Sounds like tapping fingernails on different surfaces.

Scratching: The sound of scratching materials like paper, wood, or fabric.

Role-play: Scenarios where the viewer is in a relaxing or comforting situation (e.g., personal attention like haircuts or medical check-ups).

Crinkling: Sounds from items like plastic bags or foil.

Mouth Sounds: Eating, chewing, or even the sound of speaking close to a microphone.

Psychological and Physiological Effects:
Relaxation: Many use ASMR videos to relax, fall asleep, or manage stress and anxiety.

Neurological Basis: While not fully understood, ASMR might involve the release of endorphins or oxytocin, which are associated with pleasure and bonding. Some research suggests connections to mirror neurons or synesthesia-like responses.

Individual Variation: Not everyone experiences ASMR, and triggers can be highly personal. Some find visual cues as potent as auditory ones.

Cultural Impact:
YouTube Phenomenon: ASMR has exploded in popularity on YouTube, with millions of subscribers to ASMR channels. This has created a new genre of content, with creators dedicating their channels to various ASMR triggers.

Community and Creativity: The ASMR community is active, with fans sharing their experiences, favorite triggers, and even creating their own content. This has led to a rich diversity in ASMR content types.

Scientific Research:
Emerging Field: ASMR is relatively new to scientific study, so there's much to learn. Researchers are looking into its effects on mental health, sleep, and even pain management.

Challenges: Studying ASMR is complex due to its subjective nature and the variability in what triggers it for different people.

Applications:
Therapeutic Potential: There's interest in using ASMR for therapeutic purposes, such as in relaxation therapy, although more research is needed to validate these applications.

Marketing and Advertising: Some companies explore ASMR in advertising to create a memorable or calming consumer experience.

Criticism and Controversy:
Skepticism: Some skepticism exists regarding the legitimacy of ASMR as a distinct sensory experience rather than just relaxation from soothing sounds or visuals.

Content Concerns: There have been discussions about the nature of some ASMR content, particularly in terms of appropriateness or the potential for misinterpretation.

Future Directions:
Research: As interest grows, more scientific studies will likely explore ASMR's mechanisms and applications.

Technology: Advances in audio technology, like 3D audio or VR, might enhance the ASMR experience, making it even more immersive.

ASMR remains a fascinating area of human experience, blending sensory science with personal relaxation in ways that continue to intrigue both researchers and enthusiasts alike.

The future of energy

 




The future of energy is looking greener. Moving into 2023, drivers for renewable growth are some of the strongest the industry has seen, including competitive costs, supportive policies, and burgeoning demand.


By 2024, almost 33 percent of the world’s electricity is forecast to come from renewables, with solar photovoltaic (PV) accounting for nearly 60 percent (or at least 697 gigawatts) of expected growth, according to Renewables 2019, a report from the International Energy Agency published in November 2019. Onshore wind (309 GW), hydropower (121 GW), offshore wind (43 GW), and bioenergy follow (41 GW).


Drastically lower production costs, growing concern around climate change, evolving global energy policies, and increased pressure from investors on companies to adopt environmental social governance (ESG) policies are pushing renewables into the mainstream.


This year alone, more than 12 large U.S. coal companies had filed for bankruptcy as of October 2019, in a signal of the shifting landscape. In Australia, the National Electricity Market showed that on Nov. 6, renewables reached a milestone—powering 50 percent of the country’s main electricity grid. Rooftop solar provided nearly 24 percent, followed by wind (about 16 percent), large-scale solar (about 9 percent), and hydro (about 2 percent). While renewable energy costs may continue to rise temporarily in 2023 due to ongoing supply chain challenges, wind and solar will likely remain the cheapest energy sources in most areas, as fuel costs for a conventional generation have been rising faster than renewable costs.

Federal clean energy policies. Among other supportive provisions, the IRA extends wind and solar tax credits for projects that begin construction before 2025 and technology-neutral credits through at least 2032. Projections suggest the law will spur 525 to 550 GW of new US utility-scale clean power by 2030.

State clean energy policies. Twenty-two states and the District of Columbia are targeting 100% renewable energy or 100% carbon-free electricity, often through clean and renewable energy mandates and incentives, with target dates between 2040 and 2050.

Utility decarbonization. As of October 2022, 43 of the 45 largest US investor-owned utilities have committed to reducing their carbon emissions, and boosting renewables are one of their key strategies for meeting those commitments.

Corporate renewable procurement. With a record 11 GW of US clean energy installations in 2021, the US is set to exceed that in 2022. More than 380 global businesses have committed to 100% clean electricity by joining the RE100 renewable electricity initiative, up from about 200 in 2019.




In Germany, a Norwegian company is running one of Europe’s largest power generation facilities—and doing it virtually, in an innovative example of how the sector could overcome challenges that arise when there's little wind or sun to generate power. The plant, which according to CNN Business could power 5 million homes, uses a cloud-based artificial intelligence program to link more than

1,500 wind, solar, and hydropower plants across the continent with electricity generation and storage facilities like batteries.


Renewables were the more sustainable—if more expensive—option. By 2023, they will actually make good business sense.


In 2023: The Near Future of Renewables, we present our predictions for how the sector will reimagine itself by capitalizing on this scalable green wave.

 

1. The future of solar is bright - Although slowed slightly by geopolitical tension and trade uncertainty, solar capacity will continue to grow over the next several years—surpassing a terawatt of global solar power generation by 2023. 


2. Storage takes center stage - Storage will take its rightful place as a key grid asset by 2023, helping to increase the reliability and resilience of increasingly decentralized power systems. The adoption of diverse energy storage solutions, including long-duration batteries for utility-scale renewable integration, will grow by at least 30 percent year-over-year leading up to 2023.


3. No headwinds for wind power - Wind power will continue to grow, with increased storage capabilities explicitly developed for on and offshore wind, helping to improve the economics and productivity of such projects. Half of the 2023 global investments in the wind will go towards offshore technology and projects. 


4. The energy convergence continues - Natural resources companies, from mining to oil and gas, will continue to invest in clean or renewable energy technology, including carbon capture, utilization, and sequestration—both to diversify their portfolios and reduce their corporate carbon footprints. By 2023, 20 oil and gas majors will have joined the Oil and Gas Climate Initiative, up from 13.


5. Cleantech investments soar - Following a cycle of disappointing returns, private equity and venture capital will return to the cleantech space in full force. Whether called cleantech or climate tech, the regulatory, economic, and scientific impetus for these technologies will see $600 billion dollars in global private investment by 2023.




Overall, as the industry heads into 2023, increasing demand and enticing, long-term incentives are creating strong stimuli. Of course, the uneven economy right now poses some rough sailing, but the destination is in sight and achievable. Citizens want more solar. Residential solar demand is growing faster than ever, up 35% in H1 2022 year over year, as households react to rising retail electricity prices and weather-driven power outages.

The private sector takes notice. Private investment in renewables hit a record high of $10 billion in the past year. That could continue, as investors are attracted by transparent returns on mature technologies backed by 10-year tax credits with direct payment options.

U.S. power grid

 






In 2022/2023, solar and wind are expected to add more than 60% of the utility-scale generating capacity to the U.S. power grid (46% from solar, 17% from wind). The United States is a resource-rich country with abundant renewable energy resources.


Renewables are on track to generate more power than coal in the United States this year. But the question is whether they can grow fast enough to meet the country’s climate goals.


Supply chain constraints and trade disputes have slowed wind and solar installations, raising questions about the United States' ability to meet the emission reductions sought by the Inflation Reduction Act. The Biden administration is banking on the landmark climate law cutting emissions by 40 percent below 2005 levels by 2030.


Many analysts think the United States will ultimately shake off the slowdown thanks to the Inflation Reduction Act's $369 billion in clean energy investments. But it may take time for the law’s impact to be felt. Tax guidance needs to be finalized before developers begin plunking down money on new facilities, and companies now face headwinds in the form of higher interest rates and the looming threat of a recession.


The Inflation Reduction Act's emission reductions hinge on the country’s ability to at least double the rate of renewable installations over the record levels observed in 2020 and 2021.



Assuming intermediate efficiency, solar photovoltaic (PV) modules covering 0.6% of the U.S. land area could meet national electricity demand. PV module prices have declined to an average of $0.27/watt. The U.S. manufactured 1% of PV cells and 3% of PV modules globally in 2020. In 2021, a new record high of over 23.6 GW of solar photovoltaic capacity was added in the U.S., raising the total installed capacity to over 121 GW. Solar accounted for 46% of the new generating capacity in 2021.


Hydrothermal resources, i.e., steam and hot water, are available primarily in the western U.S., Alaska, and Hawaii, yet geothermal heat pumps can be used almost anywhere to extract heat from the shallow ground, which stays at relatively constant temperatures year-round. Electricity generated from geothermal power plants is projected to increase from 15.9 billion kWh in 2021 to 47.4 billion kWh in 2050. Geothermal electricity generation has the potential to exceed 500 GW, which is half of the current U.S. capacity.


U.S. onshore wind resources have a potential capacity of almost 11,000 GW and a current installed capacity of 132.7 GW. Offshore wind resources are potentially 4,200 GW, the current capacity is 42 MW, and the development pipeline contained over 28 GW of projects in 2019. Over 16 GW of wind capacity was installed in the U.S. in 2020, an 85% increase from 2019. The federal production tax credit (PTC) significantly influences wind development, but cycles of enactment and expiration lead to year-to-year changes in investment. In 2020, the PTC was extended to allow wind projects beginning construction in 2020 or 2021 a PTC at 1.5¢/kWh for 10 years of electricity output. Based on the average U.S. electricity fuel mix, a 1.82 MW wind turbine (U.S. average in 2019) can displace 3,679 metric tons of CO2 emissions per year. By 2050, 404 GW of wind capacity would meet an estimated 35% of U.S. electricity demand and result in 12.3 gigatonnes of avoided CO2 emissions, a 14% reduction when compared to 2013.


In the U.S., net electricity generation from conventional hydropower peaked in 1997 at 356 TWh/yr. Currently, the U.S. gets about 260 TWh/yr of electricity from hydropower. While electricity generated from hydropower is virtually emission-free, significant levels of methane and CO2 may be emitted through the decomposition of vegetation in the reservoir. Other environmental concerns include fish injury and mortality, habitat degradation, and water quality impairment. “Fish-friendly” turbines and smaller dams help mitigate some of these problems.


Wood—mostly as pulp, paper, and paperboard industry waste products—accounts for 43% of total biomass energy consumption. Waste—municipal solid waste, landfill gas, sludge, tires, and agricultural by-products—accounts for an additional 9%. Biomass has low net CO2 emissions compared to fossil fuels. At combustion, it releases CO2 previously removed from the atmosphere. Further emissions are associated with the processing and growth of biomass, which can require large areas of land. Willow biomass requires 121 acres of land to generate one GWh of electricity per year, more land than other renewable sources.





For now, U.S. renewable output is edging higher. Wind and solar output are up 18 percent through Nov. 20 compared to the same time last year and have grown 58 percent compared to 2019, according to the U.S. Energy Information Administration. The government energy tracker predicts that wind, solar and hydro will generate 22 percent of U.S. electricity by the end of this year. That is more than coal at 20 percent and nuclear at 19 percent.


Renewable output also exceeded coal in 2020, though that year saw a decrease in energy generation across the board due to the economic lockdowns associated with the Covid-19 pandemic.


Wind and solar growth have to continue at a blistering pace to meet the United States' climate targets. Researchers at Princeton University estimate the country needs to install about 50 gigawatts of wind and solar annually between 2022 and 2024, or roughly double the 25 GW that the United States installed annually in 2020 and 2021.

Agrošumarstvo u sklopu Hrvatskog Centra Obnovljivih Izvora Energije (HCOIE)

  



Croatian Center of Renewable Energy Sources (CCRES) is a non-governmental organization registered and working in Croatia in the field of renewable energy, agroforestry, reforestation, and sustainable land uses. The organization started working at the CCRES Research facility in the year 2013 and has been involved with giving farmers free seeds, training farmers and the community at large on more about agroforestry techniques, and environmental conservation awareness. CCRES has been able to facilitate the planting of trees in forest lands, community farms, schools, waterlines, and private lands. Some of the benefits the farmers have been able to acquire from the organization include; free seeds, free training manuals in agroforestry, workshops in agroforestry, and sustainable land uses. 







Agroforestry takes advantage of the interactive benefits of combining trees and shrubs with crops and/or livestock.
Several types of agroforestry:
*Forest Farming: the intentional cultivation of non-timber forest crops underneath the established canopy of an existing forest.
*Forest Gardening: mimicking the structure and function of forests in the way we garden, or using the forest as a model for the way we garden.
*Silvopasture: grazing animals under a forest canopy of about 50% cover, so that grasses can persist
*Riparian Buffers: tree crop systems in waterways like streams, rivers, wetlands, etc.
*Windbreaks: tree crop systems to buffer effects of wind
*Alley Cropping: rows of trees in between conventional crops, like Black Walnuts in-between rows of corn or soybeans



Agrošumarstvo se uglavnom sastoji od miješanja sadnje stabala sa sadnjom usjeva i/ili uzgojem stoke. To omogućuje bolju iskorištenost resursa, pomaže povećanju bioraznolikosti i može povećati prinose.

U sklopu Hrvatskog Centra Obnovljivih Izvora Energije (HCOIE), objavili smo svoje nove planove za razvoj ekološki održivih šumarskih praksi diljem Hrvatske. Ovi projekti imaju za cilj smanjiti negativan utjecaj na okoliš te integrirati prakse upravljanja šumama u agroekologiju.



Agrošumarstvo se uglavnom sastoji od miješanja sadnje stabala sa sadnjom usjeva i/ili uzgojem stoke. To omogućuje bolju iskorištenost resursa, pomaže povećanju bioraznolikosti i u konačnici povećava prinose. Studija HCOIE pokazala je da parcela od 100 ha pod agrošumarskim praksama daje ekvivalent od 136 ha pod standardnim principima korištenja, dajući tako potencijalni ekonomski rast za proizvođače koje takve prakse usvoje.




Koncept ima velik broj prednosti po pitanjima uzgoja usjeva i zaštite okoliša. U principu, drveće kroz svoje korijenje stvara uvjete u tlu koji potiču bolju apsorpciju vode i minerala usjevima na površini. Agrošumarske tehnike potiču strateško pozicioniranje stabala kako bi se maksimiziralo povećanje prinosa. Dodatno, stabla pomažu u diverzifikaciji proizvodnje, ograničenju gubitaka nitrata iz tla te onečišćenju podzemnih voda.



Plodnost tla također se poboljšava padom jesenskog lišća i njegovom razgradnjom na tlu, stvarajući tako važan izvor prirodnog komposta i gnojiva okolnim kulturama. Drveće i živice na poljima povećavaju bioraznolikost, što je pogodno kukcima za oprašivanje. Konačno, stabla igraju važnu ulogu u apsorpciji CO2 i spremanju ugljika tijekom faze rasta, smanjujući tako učinak klimatskih promjena.



Agrošumarstvo tako postaje ključni igrač u agroekološkom planu HCOIE. Zbog svih ovih prednosti, promocija i širenje korištenja agrošumarstva postali su nam jedan od glavnih ciljeva u borbi protiv klimatskih promjena. Plan otkriva naše konkretne prijedloge za njegovu promociju u širokim kategorijama s brojnim specifičnim aktivnostima u svakoj od njih.





Kategorije uspostavljaju sustav za istraživanje i praćenje različitih oblika agrošumarstva koji se provode u Hrvatskoj, te uspostavljaju mreže za razmjenu informacija između različitih sudionika u agrošumarstvu. Povećanje informacija o tome što se radi u agrošumarstvu omogućit će širenje inovativnih ideja koje su u budućnosti primjenjive.



Još jedan veliki prostor na koji se odnosi plan jest poboljšanje regulatornog, pravnog i financijskog okvira koji okružuje agrošumarstvo. Neke od specifičnih aktivnosti uključuju osnaživanje financijske potpore za agrošumarstvo, poboljšanje dostupnosti alata za različite sudionike na regionalnom nivou te favoriziranje razvoja agrošumarstva kroz financijske alate.






Obrazovanje je još jedna važna komponenta plana, kako u poljoprivrednim školama, tako i u pružanju obuke već postojećim poljoprivrednicima o prednostima agrošumarstva i kako prijeći na njega. Dodatno, plan postavlja sustav pomoći kako bi se podigla vrijednost proizvedenih kultura koristeći agrošumarstvo te strategiju promocije agrošumarstva na međunarodnoj razini.



Široko korištenje agrošumarstva moglo bi imati veliku ulogu u prelasku na održive okolišne prakse u dugoročnom razdoblju, a također bi pomoglo i proizvođačima na ekonomskom nivou u povećanju prinosa, te korištenje biomase drveta, kroz malčiranje, kao prirodno gnojivo za usjeve. Predstavljeni plan trebao bi svoju primjenu naći na nacionalnom, ali i na međunarodnom nivou.





Field windbreaks

Wind protection is a long-standing indigenous practice in traditional agriculture of many regions. In attempts to improve or establish wind protection schemes with trees, it makes sense to study the link which can be observed between traditional and relatively recent but promising agroforestry practices. And it makes sense as well to try to quantify phenomena taking place in such traditional and promising practices alike.


In the case study in Croatia reported here, the farmer requested CCRES to assist in providing the agrometeorological input into the set-up of experiments under conditions in farmers' fields, with a system of wind barriers with trees, in irrigated crops in Lika Region.
The choice to use multiple tree breaks appears justified by the increase in roughness over a larger area in addition to separate windbreak effects, and by the multipurpose use of trees and their products which is economically possible. In larger-scale agriculture, where irrigated cash and food crops have to be protected against very strong winds, relatively narrow rows of trees are to be preferred above wider belts as an intercrop or scattered trees or bushes.
As mentioned earlier, where mechanical damage from strong winds is the primary limiting factor, the agronomist member of the team should pay primary attention to phenology, growth and yield parameters, and visual or even microscopic observations of actual mechanical damage. This will make it possible to observe differences between unprotected crops and protected ones at different distances from belts.


Whether in strip cropping, in using narrow tree rows, or in mixed experiments, cost/benefit ratio determinations are absolutely necessary to understand the proper gain from the multipurpose role of trees and from yield (quality) increases due to the trees or crops applied for protection from wind.

Agroforestry, forest farming, and food forest

Agroforestry, forest farming, and food forest




The terms agroforestry, forest farming, and food forest get used often in conjunction. Although they sound synonymous, in fact, they are related terms that have distinctly different definitions and practices. In today’s post, we explore these terms.




Agroforestry is the intentional integration of trees and shrubs into crop and animal farming systems to create environmental, economic, and social benefits.” So simply put, agroforestry is using trees and shrubs for some kind of benefit on the farm.


We at CCRES divide agroforestry into five major subsections. These are alley cropping, silvopasture, forest farming, riparian forest buffers, and windbreaks. So forest farming is a distinct subsection of agroforestry. To paraphrase that saying about squares and rectangles, all forest farming is agroforestry, but not all agroforestry is forest farming.




Let’s explore these five subsections.


Alley cropping is a system where trees are planted in rows for some purpose (like fruit, timber, nuts). While the farmer is waiting for those trees to mature, he plants some kind of annual between the rows of trees for short-term (annual) income.


Silvopasture is utilizing trees and livestock on a single piece of land. In general, the trees provide wind, shade, and rain shelter to the livestock. The trees themselves may be grown for timber, fruits, or nuts. The fruits and nuts may be for human or livestock consumption.




Forest farming is what everyone thinks of when the term agroforestry is used. Forest farming uses existing forests to grow food, medicinal or herbal crops with some slight manipulation of the existing forest. A classic example is using the shade of the forest to grow ginseng. Another classic example is growing shiitake mushrooms on logs from the forest under the shade of the forest.

Riparian forest buffers utilize plantings of trees, shrubs, and grasses right next to creeks, streams, and rivers. The two main purposes of riparian forest buffers are to stabilize the banks from erosion and to filter farm nutrient runoff from going into waterways.




Windbreaks are just rows of trees used to slow downwind. That being said, windbreaks have many uses. They can be used to shelter animals or buildings from wind, dust, or odors. They can be used to shelter crops from neighbors’ pesticide drift. In the Lika region, they often function as living snow fences in the winter, where snow piles naturally accumulate.




A food forest is an intentionally planned and grown “forest site.” It uses different heights of trees and shrubs to produce food at different canopy levels to maximize production. Planting is in a non-linear fashion. Food forests also utilize both the near above-ground level, ground level, and below ground level to maximize production. An example in descending height order would be chestnuts and pecans, followed by persimmons, followed by pawpaws, followed by dwarf apples, followed by comfrey (for mulching), followed by berries. Permaculturists from CCRES have been responsible for the increased popularity of food forests in Croatia over the last decade.

Permaculture Abundance / Land Equivalent Ratio




The Land Equivalent Ratio (LER) concept is considered for situations where intercropping must be compared with growing each crop sole. The need to use different standardizing sole crop yields in forming LERs is discussed, and a method of calculating an ‘effective LER’ is proposed to evaluate situations where the yield proportions achieved in intercropping are different from those that might be required by a farmer. 

The possible importance of effective LERs in indicating the proportions of crops likely to give the biggest yield advantages is discussed. Sustainable intensification of agriculture is needed to meet higher future food demands while mitigating agriculture’s ecological footprint. Intercropping is a strategy for increasing agricultural productivity per unit of land that is based on ecological mechanisms for improved resource capture. 

Here we use meta-analysis of the intercropping literature to study how the productivity of mixed systems is affected by intercrop system design and species traits. We at CCRES are focused on the effects of temporal niche differentiation between species, intercropping patterns, and relative densities. Thus, enhanced within-field crop diversity can make an important contribution to sustainable increases in food production.

Resilience

 

Resilience



Life may not come with a map, but everyone will experience twists and turns, from everyday challenges to traumatic events with more lasting impact, like the death of a loved one, a life-altering accident or a serious illness. Each change affects people differently, bringing a unique flood of thoughts, strong emotions and uncertainty. Yet people generally adapt well over time to life-changing situations and stressful situations — in part thanks to resilience.

“We have known for a long time that agroforestry can enhance resilience,” says Zeljko Serdar, from the CCRES team. “For example, trees in livestock-keeping and cropping systems provide people with diversified incomes, with food and fodder when crops fail, and they can help improve soil health.”

“This type of resilience is absolutely critical in areas such as the drylands of East Croatia where communities are struggling to cope with more frequent droughts and flash floods.”

Until recently, the exact contribution of trees to resilience in this region had been poorly explored, but in 2017 the assessment report, was published. (https://solarserdar.blogspot.com/2017/09/agroforestry-in-croatia.html ) 
It compiles what experts in research, academia, government, farmers and development practitioners already know about the links between trees and resilience in East Croatia drylands.

Studies at CCRES have shown that a 100 hectare agroforestry farm produces as much as a traditional farm of 130 to 160 hectares where trees and crops are grown separately. This finding has also led to modification of the European Common Agriculture Policy towards agroforestry.


Research on carbon sequestration, water quality protection and biodiversity at CCRES will be discussed during the session in addition to what policies and governance mechanisms are required to support agroforestry and other measures that maintain and improve environmental services.

Psychologists define resilience as the process of adapting well in the face of adversity, trauma, tragedy, threats or significant sources of stress — such as family and relationship problems, serious health problems, or workplace and financial stressors. As much as resilience involves "bouncing back" from these difficult experiences, it can also involve profound personal growth.

While these adverse events, much like rough river waters, are certainly painful and difficult, they don’t have to determine the outcome of your life. There are many aspects of your life you can control, modify and grow with. That’s the role of resilience. Becoming more resilient not only helps you get through difficult circumstances, it also empowers you to grow and even improve your life along the way.

What resilience isn’t
Being resilient doesn’t mean that a person won’t experience difficulty or distress. People who have suffered major adversity or trauma in their lives commonly experience emotional pain and stress. In fact, the road to resilience is likely to involve considerable emotional distress.

While certain factors might make some individuals more resilient than others, resilience isn’t necessarily a personality trait that only some people possess. On the contrary, resilience involves behaviors, thoughts and actions that anyone can learn and develop. The ability to learn resilience is one reason research has shown that resilience is ordinary, not extraordinary. One example is the response of many Americans to the Sept. 11, 2001 terrorist attacks and individuals' efforts to rebuild their lives after tragedy.

Like building a muscle, increasing your resilience takes time and intentionality. Focusing on four core components — connection, wellness, healthy thinking and meaning — can empower you to withstand and learn from difficult and traumatic experiences. To increase your capacity for resilience to weather — and grow from — the difficulties, use these strategies.

Build your connections
Prioritize relationships. Connecting with empathetic and understanding people can remind you that you’re not alone in the midst of difficulties. Focus on finding trustworthy and compassionate individuals who validate your feelings, which will support the skill of resilience.

The pain of traumatic events can lead some people to isolate themselves, but it’s important to accept help and support from those who care about you. Whether you go on a weekly date night with your spouse or plan a lunch out with a friend, try to prioritize genuinely connecting with people who care about you.



Join a group like CCRES. Along with one-on-one relationships, some people find that being active in civic groups, faith-based communities, or other local organizations provides social support and can help you reclaim hope. Research groups in your area that could offer you support and a sense of purpose or joy when you need it.

Foster wellness
Take care of your body. Self-care may be a popular buzzword, but it’s also a legitimate practice for mental health and building resilience. That’s because stress is just as much physical as it is emotional. Promoting positive lifestyle factors like proper nutrition, ample sleep, hydration and regular exercise can strengthen your body to adapt to stress and reduce the toll of emotions like anxiety or depression.

Practice mindfulness. Mindful journaling, yoga, and other spiritual practices like prayer or meditation can also help people build connections and restore hope, which can prime them to deal with situations that require resilience. When you journal, meditate, or pray, ruminate on positive aspects of your life and recall the things you’re grateful for, even during personal trials.

Avoid negative outlets. It may be tempting to mask your pain with alcohol, drugs or other substances, but that’s like putting a bandage on a deep wound. Focus instead on giving your body resources to manage stress, rather than seeking to eliminate the feeling of stress altogether.



Find purpose
Help others. Whether you volunteer with a local homeless shelter or simply support a friend in their own time of need, you can garner a sense of purpose, foster self-worth, connect with other people and tangibly help others, all of which can empower you to grow in resilience.

Be proactive. It’s helpful to acknowledge and accept your emotions during hard times, but it’s also important to help you foster self-discovery by asking yourself, “What can I do about a problem in my life?” If the problems seem too big to tackle, break them down into manageable pieces.

For example, if you got laid off at work, you may not be able to convince your boss it was a mistake to let you go. But you can spend an hour each day developing your top strengths or working on your resume. Taking initiative will remind you that you can muster motivation and purpose even during stressful periods of your life, increasing the likelihood that you’ll rise up during painful times again.

Move toward your goals. Develop some realistic goals and do something regularly — even if it seems like a small accomplishment — that enables you to move toward the things you want to accomplish. Instead of focusing on tasks that seem unachievable, ask yourself, "What's one thing I know I can accomplish today that helps me move in the direction I want to go?" For example, if you’re struggling with the loss of a loved one and you want to move forward, you could join a grief support group in your area.



Look for opportunities for self-discovery. People often find that they have grown in some respect as a result of a struggle. For example, after a tragedy or hardship, people have reported better relationships and a greater sense of strength, even while feeling vulnerable. That can increase their sense of self-worth and heighten their appreciation for life.

Embrace healthy thoughts
Keep things in perspective. How you think can play a significant part in how you feel — and how resilient you are when faced with obstacles. Try to identify areas of irrational thinking, such as a tendency to catastrophize difficulties or assume the world is out to get you, and adopt a more balanced and realistic thinking pattern. For instance, if you feel overwhelmed by a challenge, remind yourself that what happened to you isn’t an indicator of how your future will go, and that you’re not helpless. You may not be able to change a highly stressful event, but you can change how you interpret and respond to it.

Accept change. Accept that change is a part of life. Certain goals or ideals may no longer be attainable as a result of adverse situations in your life. Accepting circumstances that cannot be changed can help you focus on circumstances that you can alter.

Maintain a hopeful outlook. It’s hard to be positive when life isn’t going your way. An optimistic outlook empowers you to expect that good things will happen to you. Try visualizing what you want, rather than worrying about what you fear. Along the way, note any subtle ways in which you start to feel better as you deal with difficult situations.

Learn from your past. By looking back at who or what was helpful in previous times of distress, you may discover how you can respond effectively to new difficult situations. Remind yourself of where you’ve been able to find strength and ask yourself what you’ve learned from those experiences.



Seeking help
Getting help when you need it is crucial in building your resilience.

Why invest in resilience?
There’s no denying it: social, economic, climatic and environmental indicators warn of uncertain times ahead. But while some advisors may recommend investments far afield, here at CCRES we offer practical solutions close to home.

We believe that high-performance properties that merge shelter, water, renewable energy, and food with revenue generation, community development, and ecosystem and wildlife habitat restoration, provide a secure and lasting source of land-based wealth. Tangible wealth that employs and restores nature’s healthy local abundance rather than relying upon fluctuating markets and currencies.

Properly managed, this natural capital can become the living heart of your investment portfolio. A dynamic, self-sustaining and diversified asset firmly ensures your personal autonomy and resilience, enabling you to thrive no matter what.
For many people, using their own resources and the kinds of strategies listed above may be enough for building their resilience. But at times, an individual might get stuck or have difficulty making progress on the road to resilience.

Natjecanje Stablo godine (Tree of The Year) je natjecanje koje naglašava značaj starih stabla u prirodnoj i kulturnoj baštini Europe, koja zaslužuju našu brigu i zaštitu. Inspirirano jepopularnim festivalom Stabla godine koji već godinama u Češkoj Republici organizira udruga za zaštitu okoliša Nadace Partnerství. Kroz natjecanje i promocijom priča o pojedinim stablima značajnim za život lokalne zajednice cilj natjecanja je promocija bioraznolikosti i prirodnih bogatstava diljem Europske unije kako bi se podigla svijest javnosti o potrebi zaštite i očuvanja prirode, kao i važnosti prirodnih vrijednosti za život čovjeka i opstanak čovječanstva. Natjecanje Stablo godinenastoji promicati stabla i njihove priče kao prirodne spomenike na isti način na koji UNESCO promiče svjetsku baštinu.

Od 2011. godine natjecanje se održava svake godine u pojedinim državama diljem Europe. Do 2017. godine u projektu je sudjelovalo sedamnaest europskih zemalja (Njemačka, Češka, Španjolska, Francuska, Belgija, Škotska, Engleska, Wales, Bugarska, Litva, Irska, Sjeverna Irska, Engleska, Slovačka, Mađarska, Poljska, Estonija), a 2017. natjecanju sepriključila se i Republika Hrvatska prihvaćanjem kandidature Javne ustanove za upravljanje zaštićenim diejlovima prirode Dubrovačko-neretvanske županije kao nacionalnog koordinatora ispred Republike Hrvatske.Osim što je Javna ustanova za upravljanje zaštićenim dijelovima prirode Dubrovačko-neretvanske županije izabrana za nacionalnog koordinatora natjecanja Europsko stablo godine, organizator je nacionalnog natjecanja Hrvatsko stablo godine. Partneri u projektu Stablo godine Javnoj ustanovi za upravljanje zaštićenim dijelovima prirode Dubrovačko-neretvanske županije su Šumarski fakultet Sveučilišta u Zagrebu, Hrvatske šume d.o.o. te Hrvatsko agrometeorološko društvo.

Natjecanje Stablo godineima svoju proceduru i jasno propisana pravila koja nacionalni kordinator mora ispuniti i slijediti da bi se pojedina država mogla priključiti i sudjelovati u natjecanju. Natjecanje Stablo godine sastoji se od nacionalnog natjecanja i europskog natjecanja. Pobjednika nacionalnog natjecanja potrebno je proglasiti najkasnije do kraja listopada tekuće godine te gakao pobjednika nacionalnog natjecanja kandidirati ispred pojedine države za europsko natjecanje do 04. studenog tekuće godine.

Natjecanje Europsko stablo godine je finale natjecanja Stablo godine sastavljeno od pobjednika nacionalnih natjecanja. Natjecanje naglašava važnost pružanja usluga stabla u ekosustavu. Ne fokusira se na ljepoti, veličini ili dobi pojedinog stabla, već je naglasak na priči o stablu te njegovoj povezanosti s ljudima i lokalnom zajednicom. Traže se stabla koja su postala dio šire zajednice, stabla ukorijenjena u život i rad ljudi. Javno glasovanje za europsko stablo godine traje od 01. veljače do 28. veljače tekuće godine. Pobjednik natjecanja Europsko stablo godine proglašava se na Svjetski dan šuma 21. ožujka 2018. godine u Bruxelles-u s čime završava natjecanje Stablo godine (Tree of The Year) za tekuću godinu.

Organizatori natjecanja su Environmental Partnership Association, the European Landowners Organisation i TeraPark u suradnji s Europskom komisijom, pod nadležnosti povjerenika Europske komisije za okoliš, pomorstvo i ribarstvo g. Karmenu Vella.
Svrha Europskog stabla godine je istaknuti značaj starih stabala u prirodnoj i kulturnoj baštini. Europsko stablo godine ne fokusira se na ljepoti, veličini ili dobi pojedinog stabla, već je naglasak na priči o stablu i njegovoj povezanosti s ljudima. U okviru natjecanja traže se stabla koja su postala dio šire zajednice.
Svake godine na natjecanju sudjeluje više stotina tisuća ljudi. Broj uključenih država povećava se iz godine u godinu. Od prvog europskog natjecanja broj država koje su sudjelovale u natjecanju porastao je sa 5 na 17 država.

Republika Hrvatska prvi puta je sudjelovala na natjecanju Europsko stablo 2018. godine godine i zauzela je 7. mjesto kandidaturom Azijske platane Trstenom (Platanus orientalis L.) na trgu, zaštićenog spomenika parkovne arhitekture. Ove godine Republiku Hrvatsku na natjecanju Europsko stablo 2019. godine je prestavljala Gupčeva lipa, zaštićeni spomenik prirode koja je zauzela 11. mjesto.
Važno je sudjelovati u natjecanju kako bi se promovirala bogata i raznolika priroda Republike Hrvatske, a posebno ona zaštićena, najvrijedniji resurs kojim Republika Hrvatska raspolaže.
Imamo se čime dičiti i ponositi, te pokazati Europi sve vrednote kojima obilujemo.
Natjecanje Hrvatsko stablo godine je nacionalno natjecanje koje se održava u Republici Hrvatskoj.
