Lusaka, Zambia24 (20-11-2023) – In the face of mounting concerns surrounding food insecurity, malnutrition, and environmental degradation amplified by the effects of climate change, the emergence of agroecological sustainable organic agriculture (SOA) offers a glimmer of hope.
Juliet Nangamba, the programs manager at Community Technology Development Trust (CTDT), told Zambia24 in an exclusive telephone interview that agroecological sustainable organic agriculture offers a holistic approach to addressing concerns related to food, health, the environment, and agroecology.
Through insights from experts, Juliet Nangamba recognizes the transformative power of agroecology.
She said not only is agroecology a sustainable approach to agriculture rooted in ecological principles, but it also prioritizes biodiversity, soil health, and ecosystem resilience, including promoting diverse farming methods that incorporate organic matter and value traditional knowledge.
It was Nangamba’s considered view that participatory approaches that include farmer-led innovation and social equity give the power to build resilience to climate change, promote food sovereignty, and develop local markets.
“By integrating these elements, agroecology has the potential to transform agricultural systems, ensuring food security, conserving biodiversity, improving livelihoods, and promoting social justice,” she said.
She said teaching individuals to grow their own food using agroecological principles can lead to healthier diets, improved nutrition, environmental sustainability, empowered communities, and the preservation of traditional knowledge.
According to Wilfred Miga, the programs manager of Participatory Ecological Land Use Management (PELUM), embracing this approach marks a crucial turning point in our relationship with nature and agriculture. It signifies a shift towards sustainability and resilience as we recognize the need to work in harmony with the environment rather than exploiting it.
In an exclusive telephone interview with Zambia24, Miga emphasized the transformative potential of teaching people to grow their own food using agroecological principles. This approach empowers individuals and communities at multiple levels.
On an individual level, it provides individuals with the knowledge and skills to become self-sufficient and take control of their own food production.
“By growing their own food, they not only have access to fresh, healthy produce but also gain a deeper understanding and appreciation of the natural processes that sustain life.”
At a community level, promoting agroecology fosters a sense of unity and cooperation. It encourages community members to come together and share resources, knowledge, and expertise to collectively enhance their food production and resilience.
“This communal effort not only strengthens social ties but also leads to increased self-reliance and a sense of empowerment,” he said.
However, Miga said the benefits of agroecological practices extend far beyond personal empowerment.
“One of the most significant advantages is the promotion of food security. Diversifying agricultural practices and relying less on monocultures and chemical inputs will build resilience against climate change impacts and pests,” he said.
“It also promotes soil health through organic farming techniques, reducing the need for chemical fertilizers and pesticides. This approach leads to healthier soils, increased biodiversity, and more robust ecosystems, which in turn support sustainable food production,” he added.
Furthermore, Miga explained that agroecology encourages the conservation of natural resources and the protection of ecosystems.
He said prioritizing sustainable farming techniques like water conservation methods and agroecological practices will contribute to the preservation of biodiversity, soil fertility, and water quality.
“This emphasis on ecological stewardship ensures the long-term viability of agricultural systems and enhances the overall health of our planet,” he said.
Rolf Shenton, an esteemed environmentalist and activist, passionately emphasizes the immense potential of agroecology in revolutionizing the way we perceive and approach food.
Shenton educates and raises awareness about the transformative power of agroecology in enhancing the nutritional value of our food.
Agroecology, as Shenton explains, takes a holistic approach to agriculture that revolves around the intricate interactions and interdependencies between crops, soil, and biodiversity.
Unlike conventional farming practices that often rely on synthetic fertilizers, pesticides, and genetic modification, agroecology embraces sustainable and organic methods that prioritize the health of the environment and ecosystems.
He said nurturing and preserving the natural balance within agricultural systems will unlock the full potential of crops to provide not only sustenance but also a wealth of essential nutrients.
“One of the most notable advantages of agroecologically-grown food is its elevated levels of essential micronutrients. Through techniques like crop rotation, intercropping, and the use of cover crops, farmers can enhance the soil’s fertility and structure, facilitating the absorption of crucial minerals and trace elements by plants.”
As a result, Shenton said, the nutrient content of agroecologically grown food surpasses that of traditionally cultivated crops, ensuring a more nourishing and balanced diet for consumers.
Furthermore, Shenton said agroecology is also renowned for fostering the production of crops packed with powerful antioxidants. The preservation of natural ecosystems, including forests, wetlands, and grasslands, promotes biodiversity and provides a habitat for a diverse array of species, including beneficial microorganisms and insects.
“These organisms play a vital role in the natural defense mechanisms of plants, encouraging the production of antioxidant compounds that protect crops from pests, diseases, and environmental stressors. When consumed, these antioxidants not only safeguard our bodies against oxidative damage but also offer numerous health benefits, such as reducing inflammation and strengthening the immune system,” he said.
In addition to micronutrients and antioxidants, Shenton explained, agroecological practices also promote the accumulation of beneficial phytochemicals in crops.
“Phytochemicals are natural compounds found in plants that have been extensively studied for their potential health-promoting properties. They are known to have anti-inflammatory, anticancer, and cardiovascular protective effects, among others,” he said.
He added, “Through the intricate web of relationships fostered by agroecology, plants are stimulated to produce higher levels of these valuable phytochemicals, offering consumers a wide range of health benefits with each bite.”
The impact of agroecology extends far beyond individual health and nutrition. Reducing reliance on synthetic inputs and embracing sustainable practices, agroecology contributes to the protection and restoration of ecosystems.
It promotes soil health, water conservation, and biodiversity preservation, safeguarding vital resources for future generations. Additionally, agroecology champions the resilience and adaptability of farming communities, fostering social and economic sustainability.
Shenton also shed light on the transformative potential of agroecology in enhancing the nutritional value of our food.
“By embracing sustainable farming practices and prioritizing the preservation of natural ecosystems, agroecology paves the way for crops that are abundant in essential micronutrients, invaluable antioxidants, and beneficial phytochemicals.”
He added, this, in turn, will lead to healthier diets, improved overall health, and a more sustainable and resilient future for agricultural systems and communities.
Shenton further puts a spotlight on the critical importance of agroecology when it comes to environmental conservation and ecological restoration.
“The innovative techniques employed in agroecology, such as polyculture and agroforestry, play a pivotal role in preserving our planet’s precious biodiversity,” he said.
He said implementing these methods can simultaneously bolster soil fertility and minimize the occurrence of detrimental pests and diseases.
“The advantages brought by agroecology extend beyond these immediate benefits, as they also have a profound impact on addressing climate change. Specifically, agroecological practices contribute significantly to carbon sequestration, which effectively offsets the release of harmful greenhouse gases into the atmosphere,” he said.
This, in turn, aids in mitigating the adverse effects of climate change and fosters a more sustainable and resilient agricultural system,” he added.
Additionally, Shenton said agroecology plays a vital role in safeguarding our water resources, a critical aspect of environmental conservation.
He said employing these techniques will limit the pollution of water sources, ensuring their continued availability and purity for both agricultural and human needs.
“This proactive approach fosters a more sustainable water management system, vital for the preservation of our ecosystems and the well-being of future generations,” he explained.
Shenton sheds light on the invaluable environmental benefits that agroecology offers.
“Through practices like polyculture and agroforestry, we can enhance biodiversity, bolster soil fertility, and mitigate pests and diseases,”
Furthermore, Shenton explained, agroecology provides invaluable contributions to carbon sequestration, climate change mitigation, and the protection of water resources, thereby forging a path towards a more sustainable and resilient agricultural system and a healthier planet overall.
Empowering Local Communities and Ensuring Food Sovereignty
Simon Mwamba, an advocate for sustainable agriculture, emphasizes the social and economic advantages of agroecology.
“Prioritizing local food production reduces dependence on global food systems and empowers individuals to control their food supply. This localization fosters social cohesion, creates employment opportunities, and ensures access to diverse diets.”
Preserving Traditional Knowledge and Indigenous Practices
Royd Michelo, an official from Seed Knowledge Initiative (SKI), acknowledges the value of agroecology in preserving traditional knowledge and indigenous practices.
He said respecting and integrating traditional and indigenous ecological knowledge supports the preservation of sustainable farming practices. This recognition fosters cultural identity and promotes resilient, locally-adapted agricultural systems.
Addressing Climate Change and Building Resilience
Christopher Hamanjanji, an agroecological practitioner, acknowledges the importance of agroecology in addressing climate change and building resilience in food systems.
Hamanjanji said agroecology promotes water conservation, diversified and resilient farming strategies, and the use of organic matter to improve soil structure, strengthening the system’s ability to withstand extreme weather events. By implementing these practices, farmers can adapt to the challenges posed by climate change and ensure the long-term sustainability of their food production.
