Cultivating a Greener Agriculture with the Istanbul Agriculture ROTARY Club, RID2420
Across Türkiye, Uganda and other farming regions, communities are confronting water scarcity, soil degradation and changing growing seasons. The Istanbul Agriculture ROTARY Club argues that resilient agriculture begins with healthy soil, locally appropriate solutions and long-term collaboration.
Introduction
Agriculture is never only about crops. It is also about water, soil, livelihoods, culture, technology and the relationships that enable communities to respond to change.
In his Earth Talks presentation, Turkish civil engineer and agricultural specialist Ali Gökçe Yaşar explored how these connections are shaping agriculture in Anatolia, the Mediterranean and beyond. Drawing on the work of the Istanbul Agricultural Rotary Club and its partners, he described a practical vision of farming that protects biodiversity while strengthening food security and rural economies.
Their central message was hopeful but demanding: sustainable agriculture cannot be delivered through a single technology or short-term grant. It requires communities to understand their local conditions, measure results, share knowledge and remain involved through complete growing and harvesting cycles.
Agriculture Begins with Place
Anatolia lies within one of the world’s historically significant agricultural regions. Its varied landforms, soils and microclimates have supported crop cultivation and animal husbandry for thousands of years.
Yaşar connected this agricultural diversity to the geological forces that formed the mountain belt stretching from southern Europe through Türkiye and toward the Himalayas. These landscapes create sharply different growing conditions over relatively short distances. A method that succeeds in one valley may be unsuitable in another.
Key Takeaways
- Healthy soil is the foundation of food security, biodiversity and resilient rural livelihoods.
- Agricultural solutions must reflect local climate, water, soil, crops and community needs.
- Regenerative practices can restore damaged soil while farms continue producing food.
- Data helps farmers measure results, anticipate change and improve future growing seasons.
- Long-term cooperation must continue through planting, harvest, processing and sales.
This is why agricultural projects must begin with regional circumstances rather than imported assumptions. Water availability, soil composition, seasonal temperatures, local crops and market demand all influence which solutions will work.
The same principle applies internationally. Türkiye experiences distinct seasons and generally one major annual harvest, while equatorial Uganda may support two production cycles without a winter period. Cooperation can transfer knowledge between regions, but each practice must be adapted to local climate and ecology.
Healthy Soil Supports Healthy Communities
Yaşar presented soil, food, people, technology, and international cooperation as interconnected pillars of sustainable agriculture. Of these, soil is the foundation.
Soils affected by intensive pesticide use, industrial residues or declining organic matter cannot always transition immediately to certified organic production. Regenerative agriculture can provide a practical pathway. The term describes farming practices intended to restore soil fertility, improve water retention and support biodiversity while continuing to produce food.
“Healthy soil sustains biodiversity and is the foundation of everything we do.” The Istanbul Agriculture ROTARY Club
This may include composting, reducing harmful chemical inputs, maintaining ground cover, and using locally produced biological preparations to manage pests.
Yaşar described cooperation between agricultural Rotarians in Türkiye and the Kinoni Rotary Club in Uganda. Partners discussed plant protection methods using substances such as vinegar or garlic to repel insects rather than eliminate them indiscriminately. The objective was to protect crops while preserving beneficial organisms.
These experiences demonstrate an important distinction: agricultural success is not simply a larger harvest. It also includes healthier soil, safer food, stronger biodiversity, and farmers who can sustain their work economically.
Climate Resilience Requires Measurement and Adaptation
Early in his discussion of climate pressures, Yaşar emphasized the need to prepare before conditions become more severe. “We have to take precaution even earlier.”
Changing rainfall, rising temperatures and drought risks are already influencing farm decisions. Yaşar pointed to rainwater collection, efficient irrigation and controlled-environment systems such as hydroponics and aquaponics as possible responses. Hydroponics grows plants without soil, while aquaponics combines plant cultivation with fish production in a recirculating water system.
Technology, however, is valuable only when it responds to a real local need. Farmers need usable information about rainfall, soil condition, crop quality, yields and market performance. Consistent records can help communities evaluate one season and make better decisions for the next. “Technology should help us digitally monitor sites and establish databases.”
Measurement also allows project partners to define success more clearly. Useful indicators might include soil organic matter, compost use, pesticide reductions, the number of farmers trained, food produced, women and young people participating, and households gaining access to healthy food.
Data should not replace farmers’ experience. Instead, it can strengthen that knowledge, helping growers recognize emerging patterns that differ from the seasons their families have known for decades.
“Technology should help us monitor sites and prepare for future seasons.” The Istanbul Agriculture ROTARY Club
Training is equally important. School gardens, farmer workshops and community demonstrations can turn abstract sustainability goals into everyday skills. Children can learn composting and food production directly, while producers can compare methods and coordinate their actions.
Cooperation Must Last Beyond a Funding Cycle
Agricultural transformation takes time. A project cannot be judged only by whether equipment was delivered or a training event was completed. It must continue through planting, cultivation, harvesting, processing and sales. “Agriculture is not like having project funding and giving it away. Agriculture requires a term.”
Yaşar outlined a collaborative model in which interested groups first exchange information, identify stakeholders and funding partners, prepare documentation and secure district support. From there, projects require regular meetings, site visits, shared publications and ongoing evaluation.
“Agriculture requires time, from planting through harvest and income.” The Istanbul Agriculture ROTARY Club
Cooperatives can play an especially valuable role. By organizing collectively, smallholder farmers may gain access to equipment, technical advice, processing facilities and stronger markets that would be difficult to reach individually.
Women and young people should be central to this process. Yaşar highlighted women’s roles as producers, educators and holders of practical agricultural knowledge. Supporting them can strengthen entire households and help transfer skills to younger generations.
International partnerships are most successful when they do not impose standardized solutions. Their role is to connect professional knowledge with local experience, help communities obtain suitable resources and create systems that can continue after external support ends.
Practical Takeaways & Implications
Yaşar’s presentation offers a useful framework for Rotary clubs, nonprofits, educators and community leaders considering agricultural projects.
Begin with local evidence. Study soil, water, climate, existing crops and community priorities before selecting technologies or funding equipment. A highly advanced system is not automatically the most sustainable one.
Design projects around full agricultural cycles. Budgets and reporting schedules should recognize that farmers may need six months, a year or longer before outcomes can be evaluated.
Measure environmental and social results together. Crop yield matters, but so do soil health, biodiversity, farmer income, food quality, training and participation by women and young people.
Support knowledge exchange rather than one-way instruction. Farmers already possess valuable experience. Outside specialists can contribute most effectively by testing ideas with communities and adapting recommendations to local conditions.
Finally, make sustainable practices visible and accessible. Composting household and garden waste, collecting rainwater, creating school gardens and monitoring soil conditions are practical entry points. Individually, they may appear modest. Together, they can build the habits and knowledge needed for more resilient food systems.
The future of agriculture will not depend on one crop, country or institution. It will be cultivated through patient cooperation among people who understand that caring for soil also means caring for communities.

Growing Climate Leaders One School at a Time with Felix Kariuki
A Kenyan initiative is turning school grounds into living classrooms where students restore nature, grow food and build practical leadership skills.
Across western Kenya, a different kind of climate education is taking root. Students are not only learning about environmental change from textbooks. They are selecting seeds, preparing compost, testing soil, raising indigenous trees and growing food.
This hands-on approach is at the heart of Seeds of the Future, an initiative presented by engineer and sustainability leader Felix Kimani Kariuki during the 30 July 2026 Earth Talks program.
Its goal is ambitious but practical: help children become capable environmental stewards while they are still in school.
“Why don’t we grow climate leaders from school itself?” Kariuki asked. Schools, he explained, are trusted community institutions. When environmental learning becomes part of daily school life, children can carry that knowledge home, influence their families and eventually help shape better public policy.
From Depleted Farmland to a Place of Learning
The story begins at the Mary Okello Conservancy near Kenya’s Nandi Escarpment, an important water source for Lake Victoria.
The land had long been used for sugarcane cultivation. Over time, repeated production and chemical use contributed to depleted soil and declining biodiversity. Dr. Mary Okello set aside approximately 200 acres to demonstrate that the landscape could be restored and used differently.
Key Takeaways
- Schools can turn climate education into practical skills through nurseries, gardens and composting.
- Students learn to raise indigenous trees suited to their local ecosystems.
- Fruit trees and vegetable gardens connect environmental restoration with better nutrition.
- Selling surplus seedlings can teach financial literacy and help sustain school programs.
- Children carry climate knowledge home, creating change from the community level upward.
Trees were planted, soils were renewed and the former plantation began developing into a conservancy. It also became a learning centre for schools, visitors and farmer field schools—practical programs where farmers learn by observing and testing methods in real conditions.
But bringing students to the conservancy was only a beginning. The project’s leaders wanted schools to create their own small areas of restoration and food production.
Seeds of the Future, founded by Joseph Okello, emerged from that vision. Rather than treating environmental education as an occasional field trip, the program helps schools build permanent spaces where students can learn by doing.
Learning the Full Life Cycle of a Tree
“Why don’t we grow climate leaders from school itself?” Kariuki asked.
The question captures the program’s central idea. Instead of waiting for young people to become adults before involving them in climate solutions, Seeds of the Future gives them practical responsibility now.
“Why don’t we grow climate leaders from school itself?” Eng. Felix Kariuki
The project goes beyond distributing seedlings for a ceremonial planting day. Participating schools receive approximately 90 days of guided support. Students and teachers work together to establish a nursery and learn the full process of raising healthy plants.
“We’re making it practical—not just theoretical, but practical,” Kariuki said.
Activities include selecting locally appropriate seeds, propagating seedlings, making compost, assessing soil and understanding the nutrients plants need.
The program works with knowledgeable partners, including the Kenya Forestry Research Institute, to identify species suited to each location. This matters because planting the wrong tree in the wrong place can waste resources or disrupt local ecosystems.
Indigenous trees are a central priority. Native species are adapted to local conditions and can provide habitat for wildlife, protect soils and support the wider ecological relationships that make a landscape resilient.
“We’re making it practical—not just theoretical, but practical.” Eng. Felix Kariuki
Students also grow fruit trees and vegetables. This broadens the project from tree restoration into an integrated lesson about biodiversity, nutrition and food security.
By following the complete life cycle of a plant, students learn that successful restoration requires more than putting a seedling in the ground. It requires appropriate species, healthy soil, water, monitoring and long-term care.
Climate Education That Also Addresses Hunger
For Kariuki, environmental action cannot be separated from people’s daily needs.
Many communities face both ecological decline and unreliable access to nutritious food. School gardens and nurseries can help address those challenges together.
Fast-growing vegetables can supplement school meals. Fruit trees can provide food over many years. Regenerative multi-storey gardens—compact gardens designed to grow crops in layers—can help schools produce vegetables where land or water is limited.
Students learn that soil health, water protection, biodiversity and human health are connected. They also gain skills they can use at home or carry into future employment.
The approach reframes climate leadership. It is not limited to public speeches, international conferences or national policy. It can begin with knowing how to make compost, keep a seedling alive and grow food without exhausting the soil.
By giving young people the ability to act, the program also replaces helplessness with competence. Climate change can feel distant and overwhelming, particularly to children. Caring for a nursery offers a visible task and a measurable result.
Growing Skills—and Financial Independence
Seeds of the Future also introduces students to enterprise and financial literacy.
Schools can use some of what they grow while selling surplus seedlings or produce. Financial partners can then help students understand saving, reinvestment and responsible management.
The aim is not to turn every school into a business. It is to help programs become more self-sustaining while showing students how environmental restoration can create social and economic value.
Kariuki described the model as teaching someone to fish rather than simply giving them a fish. Students learn how to establish a nursery, care for it and use its outputs to support the next cycle of planting.
This structure also improves the likelihood that projects will survive after an initial donation or launch event. Teachers are involved from the beginning, and schools develop the knowledge needed to continue the work.
At the time of Kariuki’s presentation, more than 12,000 students had participated. The long-term aspiration is to reach every school possible.
Children Can Move Communities
“The youth are eager,” Kariuki said. “They’re hungry to do something to make a difference.”
One of the program’s most powerful ideas is that environmental learning travels.
A child who learns about composting, tree care or water conservation may return home and share that knowledge. Students can question wasteful habits, encourage relatives to plant appropriate trees and demonstrate methods their families have never encountered.
This bottom-up influence may sometimes be more effective than instructions delivered from institutions far away.
“The youth are eager. They’re hungry to do something to make a difference.” Eng. Felix Kariuki
Young people, Kariuki argued, already want to contribute. They understand that their future depends on clean air, healthy land and reliable food. What many lack is not motivation but a practical framework.
Seeds of the Future provides a place to begin. A school nursery gives students a manageable project, visible progress and responsibility for living things.
It also allows leadership to grow gradually. Students learn to cooperate, solve problems and care for resources before they are asked to lead organizations or influence policy.
Practical Takeaways & Implications
The Seeds of the Future model offers useful lessons for schools, Rotary clubs, nonprofits, local governments and funders around the world.
First, climate education is most effective when students can apply it. A small nursery, pollinator garden, composting site or vegetable plot can transform abstract lessons into practical understanding.
Second, locally appropriate knowledge matters. Schools should work with forestry agencies, farmers, Indigenous knowledge holders, conservation groups or universities to select suitable species and methods.
Third, long-term care must be designed into every planting project. Trees need water, protection and monitoring after the launch photographs have been taken. Training students and teachers together creates continuity.
Environmental projects also become stronger when they address community priorities. A school nursery can restore biodiversity, improve nutrition, build vocational skills and create modest income at the same time.
Rotary clubs and other service organizations can help by funding materials, connecting schools with technical partners, supporting teacher training and providing mentorship. Every form of support can help a school move from a one-day activity to an enduring environmental program.
A seedling may be small, but the habits formed while caring for it can last a lifetime. By investing in practical climate education now, communities can raise a generation that sees environmental stewardship not as a special activity, but as part of everyday life.
