Positive Solutions for Nature in Colombia: A Review

Written by dmedina on April 24, 2025. Posted in News.

In a world where environmental and agrifood challenges demand urgent responses, the CGIAR-led Positive Solutions for Nature (Nature+) initiative is transforming agriculture into a catalyst for ecological regeneration and sustainable development.

In Colombia, CIMMYT has played a key role in implementing several activities under this initiative. These efforts have not only improved agricultural productivity but also promoted biodiversity conservation, sustainable resource management, and the strengthening of rural communities—with a special focus on youth, women, and native maize.

One of the first steps in Colombia was conducting a diagnosis and mapping key actors within agrifood systems across different regions. This assessment identified major challenges such as limited access to native seeds, soil degradation, and lack of access to fair market opportunities for smallholder farmers.

To ensure that promoted practices aligned with local realities and needs, CIMMYT worked closely with farmers to co-create solutions. A significant example was the support given to women producers to conserve native maize varieties. Workshops held in Cesar, Nariño, Putumayo, and Valle del Cauca included childcare spaces, enabling full participation by women.

Another important milestone was facilitating dialogue between producers and niche markets, helping connect farmers growing native maize with potential buyers. This has been key to revitalizing the value chain for these crops. In parallel, twelve community seed banks were strengthened in various regions, ensuring the availability of native varieties and encouraging intergenerational knowledge exchange.

CIMMYT also conducted extensive training activities, benefiting hundreds of farmers in the post-harvest management of native grains and seeds. In workshops held during 2023 and 2024, over 780 producers—many of them women—received training in practices such as harvesting, drying, shelling, and hermetic storage, which reduced post-harvest losses and improved seed quality.

Infrastructure improvements further supported these efforts. One standout example is the YEL-PUE Cumbe seed bank in Cumbal, Nariño—established with support from CIMMYT and the Bioversity-CIAT Alliance. This seed bank not only conserves agricultural biodiversity but also serves as an intergenerational learning hub, where farmers, students, and technicians share experiences and knowledge.

A key component of the initiative has been youth participation. Through collaboration with the José María Falla Educational Institution and youth networks like Herederos del Planeta, students have engaged in agroecological maize production. This involvement fosters stronger rural ties and ensures the continuity of traditional knowledge for future generations.

While challenges remain, the implementation of Positive Solutions for Nature in Colombia has demonstrated that agricultural production can go hand in hand with environmental conservation and community well-being. Thanks to collaborations with research centers such as CIMMYT, many Colombian farmers are now adopting regenerative practices, enhancing agrobiodiversity and boosting resilience to both climate and economic shocks.

Looking ahead, these efforts will continue within the CGIAR Multifunctional Landscapes Science Program. CIMMYT, in collaboration with other CGIAR centers, will focus on participatory varietal selection, business models to enhance the value of agrobiodiversity, connections to niche markets, and the empowerment of women as agents of biodiversity conservation.

Caring for the Earth to Secure the Future

“The conventional way we used to prepare the land involved heavy soil disturbance, and now we see that’s not necessary. We used pesticides that were, let’s say, not kind to the soil. Now, we are becoming increasingly mindful of the environment — and it turns out to be more profitable. Today, I wouldn’t dare use a pesticide or any polluting product that could harm people or the environment.”

Leopoldo is a farmer from Sinaloa participating in the Supporting Responsible Sourcing in Mexico project — a collaboration between Kellogg Company and CIMMYT. For him, ceasing the practice of burning crop residues and instead using them to cover and protect the soil from erosion signifies a shift in values and a better way of practicing agriculture — one that actively contributes to regenerating the Earth.

The agronomic innovations adopted by farmers involved in the project promote a more balanced relationship with nature, aiming to strengthen a responsible sourcing model that ensures equilibrium between the economic, social, and environmental needs of both current and future generations. This contributes to a more sustainable production and consumption model, capable of feeding a growing global population within planetary boundaries.

If current patterns of production and consumption persist, it is estimated that in less than 30 years we would require the resources of three Earths to meet global needs. The rising scarcity of water and the reduction in arable land—driven by urban expansion and soil degradation—are clear reminders that our planet’s natural resources are finite. These facts underline the urgent need to accelerate the adoption of sustainable practices in agrifood systems.

Within the observance of International Mother Earth Day, efforts like the Supporting Responsible Sourcing in Mexico project serve as a reminder of the importance of forging a new relationship with the planet. Above all, they emphasize recognizing the Earth and its ecosystems as the shared home of all humanity. Failing to care for this home could lead us into further crises — in health, socioeconomic stability, and food security — and agriculture offers powerful solutions to safeguard this common home.

Globally, the agriculture sector is responsible for 24% of greenhouse gas emissions — which contribute to climate change — and 70% of freshwater withdrawals from rivers, lakes, and aquifers. Additionally, for every 1°C increase in global temperature, cereal yields are estimated to decrease by about 5%. Therefore, a new model of sustainable production and consumption must aim for reduced environmental impact, while increasing productivity and delivering benefits for farmers.

The Conservation Agriculture practices promoted by the Kellogg-CIMMYT project are advancing these goals: in just three years of work in Sinaloa and Guanajuato, nearly 7,000 hectares have adopted sustainable agricultural practices, leading to a 36% increase in average maize productivity. In 2021 alone, more than 350 farmers were engaged across over 2,400 hectares, producing nearly 26,000 tons of yellow maize through sustainable intensification technologies.

Looking ahead, the initiative aims to impact around 20,000 hectares to produce close to 180,000 tons of maize with a reduced carbon footprint. Already, farmers have achieved reductions in fuel use for grain production and improved water-use efficiency in irrigation.

“We save on machinery, on fuel, on agrochemicals, and on fertilizers. Now we produce with higher quality and at a lower cost because we practice minimal tillage. They also teach us integrated pest management and even how to optimize fertilizer use,” says Leopoldo, highlighting a system that also eliminates crop burning, one of the leading causes of wildfires.

By providing farmers with the knowledge and tools they need to integrate sustainable production methods, we benefit not only the Earth — but all of humanity.

During this challenging period, Sonia came across a YouTube video showcasing a combine harvester—a cutting-edge machine that could revolutionize harvesting. She immediately recognized its potential to transform farming practices and offer a reliable income stream. The first major hurdle was overcoming her family’s financial constraints and convincing them to invest in a machine without any tangible proof of its benefits.

In October 2020, Sonia and her family attended a live demonstration organized by the private sector, where she successfully persuaded her father to invest in a combine harvester. With the support of a machinery subsidy, she selected the best model suited to her business needs.

Sonia took part in business expansion meetings, built linkages with spare parts shop owners, dealers, and commission agents, and received operational and maintenance training—for both herself and her machine operators.

In the first season of 2021, Sonia’s combine harvester generated an impressive income of approximately US$10,000 (excluding operational and labor costs). This early success fueled her ambition, and with her family’s support, she invested in a second combine harvester, expanding the business.

Today, Sonia Jannat proudly owns three combine harvesters, generating an annual income of BDT 30 lakh (approximately US$33,000). Her customer base has grown to span around ten geographical divisions across Bangladesh. Sonia’s achievements have not only reshaped her own financial future but have also broken deep-rooted societal stereotypes. Once ridiculed for her unconventional path as an unmarried woman, she now commands respect and admiration from the very community that once doubted her.

Sonia shares with pride:

“The same society that once criticized me with comments like, ‘Why is an unmarried girl traveling around to earn money? Why is she breaking social norms?’ is now praising me. After witnessing my talent, social contributions, and support for my family, they now see me as one in a thousand girls!”

With academic credentials that include honors and a master’s degree in Bangla, Sonia’s aspirations continue to grow. She now envisions launching a new entrepreneurial venture offering a wider range of agricultural machinery services. She is committed to empowering women by actively engaging them in her business model—aiming to be an inspirational entrepreneur for many others.
