West Africa’s ecosystems are transforming, reshaping its vast savannas into forest islands or arable lands. This change, mainly driven by human activity, has profound implications for soil health and ecosystem sustainability.

Researchers from Institut de L’Environnement Et de Recherches Agricoles, Burkina Faso; Crop Research Institute (CSIR), Ghana; Kwame Nkrumah University of Science and Technology (KNUST), Ghana; Imperial College of Science and Technology, London; Wageningen University, Netherlands; Federal University of Agriculture, Abeokuta (FUNAAB), and the International Institute of Tropical Agriculture (IITA), have explored these impacts, shedding light on how land-use changes affect soil organic matter (SOM) and key soil quality indicators, such as macro- and micronutrients.

The study revealed that when savannas transition into forest islands, soil health significantly improves. The SOM in the topsoil rose dramatically—up to 794%—and the abundance of essential nutrients such as potassium, calcium, and magnesium surged. These improvements are attributed to the favorable microclimate and nutrient cycling fostered by forest ecosystems.

Conversely, converting savannas to arable land paints a more concerning picture. The SOM levels plummeted up to 74%, particularly in topsoil layers. This decline compromises the soil’s productive capacity, making it prone to erosion, reduced aggregation, and decreased activity of beneficial soil organisms. Despite efforts to enrich soils through fertilization, the benefits of these practices often fall short of compensating for the inherent losses caused by the transition.

The role of local communities in preserving soil health cannot be overlooked. The study highlights how indigenous land management practices have contributed to the formation of forest islands, countering earlier misconceptions that these patches were remnants of ancient forests. These community-driven efforts offer valuable lessons in sustainable land stewardship and could inform strategies to mitigate the adverse effects of climate change on resource-poor agrarian systems.

The research showed that soil quality indicators vary significantly by land use type and geographic location. For instance, nutrient-rich soils and intensive farming practices at one site in northern Ghana, led to better soil quality in arable lands than in forest islands or savannas. However, this was an exception rather than the rule, with forest islands generally outperforming other ecosystems in soil health.

With the growing demand for food production, there is also an urgent need to convert more savannas into farmland. The findings underscore the urgent need to adopt sustainable farming practices. Techniques such as agroforestry, improved crop rotation, and soil conservation methods could help offset the negative impacts of land-use changes.

As we look ahead, the study offers a hopeful perspective. Restoring marginal lands as forest islands enhances soil fertility and contributes to overall ecosystem health. As West Africa grapples with balancing agricultural expansion and ecological preservation, embracing indigenous practices and promoting sustainable land use could hold the key to a more resilient future.

This research adds a critical voice to the global conversation on land use and climate change, highlighting how localized solutions can make a significant difference in safeguarding soil health and improving food security on the continent.

Vegetable farmers in the Democratic Republic of the Congo are building their capacity in the production of organic fertilizer under the IITA BSF for Bio Circular Economy and Environmental Sustainability (IITA-BBEST) Project, in partnership with the National Institute for Agronomic Study and Research (INERA). A practical training workshop for 50 people, including 24 men and 26 women was organized on 6 January 2025, at the University of Kinshasa (UNIKIN) to equip these agripreneurs with knowledge on the production of organic fertilizer from the Black Soldier Fly residue (frass). This training is part of implementing the (BSF for Bio Circular Economy and Environmental Sustainability) IITA-BBEST Project, the activities funded by the Norwegian Agency for Development Cooperation (NORAD).

This workshop was structured in two parts. The first part focused on rearing the black soldier fly (BSF) with a general overview of its origin and some fundamental characteristics of the species that make it a good candidate for rearing without risk for humans and animals. These characteristics are the expansion of the species throughout the intertropical zone despite its American origin, its wealth in proteins and lipids, making it an extremely interesting alternative source of feed for different livestock sectors (chickens, fish, and pigs), and its harmlessness to humans (i.e., does not bite).

It was highlighted that using BSF larvae for animal nutrition and organic fertilizers from livestock farming for market gardening is an innovative and sustainable solution that offers farmers an effective way to reduce costs while increasing their productivity. Also, integrating black soldier fly larvae and organic fertilizer into agriculture helps to preserve the environment.

After the explanations on breeding the black soldier fly, the participants visited the black soldier fly larvae production unit to follow the different rearing stages, starting with the collection of waste and ending with obtaining the fly, including the collection of eggs, pre-pupae, and pupae.

The second part of the workshop was to train the participants on using organic fertilizers from the larvae of the black soldier fly. It was mentioned that the residues obtained after the digestion of organic matter by the larvae constitute a rich fertilizer and can be used after composting as an organic amendment to fertilize crops. It was recalled that organic fertilizer makes it possible to grow healthier vegetables and reduce the ecological footprint. Participants were advised to opt for these agroecological practices to ensure sustainable management of their resources by reducing chemical inputs. The participants visited some flower beds made and fertilized with the black soldier fly larvae organic fertilizer at the University of Kinshasa.

Eight members of the IITA BBEST project beneficiaries in Kinshasa participated in this workshop to increase their knowledge. These include two members of the Agricultural Cooperative of the Center of Kimbanseke (COOPACEK), two members of the Agricultural Cooperative of the Center Maraicher of N’djili (COOPACEN), two members of the Association of Fish Farmers for Development in Congo (APIDEC) and two members of the Judith farm.

This training ended with the presentation of a certificate to each participant.

Kicking off the IITA Knowledge Café series for 2025, Shakiru Quadri, the IITA Technical Advisor for the CGIAR Fragility, Conflict and Migration (FCM) Initiative, delivered an insightful presentation on his research work. The discussion, which was held on 22 January and coordinated by IITA Director for Sahel Africa Hub Tahirou Abdoulaye, focused on the impact of climate change on household food security in the semi-arid regions of Nigeria.

Quadri mentioned that the study was inspired by his research team’s experience working in fragile and conflict-affected areas of Nigeria. These regions are uniquely vulnerable to climate change due to their reliance on natural systems and resources critical for survival in dryland environments. He added that climate change has become a pressing issue globally, significantly affecting agriculture and food security. This reality spurred researchers to investigate the implications for communities in northern Nigeria.

Conducted in the semi-arid eco-climatic zone, where recurrent droughts and conflicts are common, the study analyzed data from 626 respondents across three states: Borno, Katsina, and Sokoto. Using secondary data from the Food and Agriculture Organization (FAO) alongside cross-sectional data, the team employed multi-stage sampling techniques and specified several linear and non-linear models to analyze the trends.

The study showed that food security across the three states is highly vulnerable to climate variability, with a statistically significant impact at the 1% level. Forecasts for five years (up to 2025) shows a continued decline in food availability. A combined normalized livelihood exposure index of 0.79 indicates a high level of exposure to climate risks, while the adaptive capacity remains moderate at 0.35. The data revealed a 51% reduction in household food availability due to conflicts. Also, variables such as rainfall, drought, temperature, and conflict were found to significantly affect food security at both 1% and 5% significance levels.

The study concluded that climate variability and extreme weather events, compounded by disruptions from the COVID-19 pandemic, rising fertilizer and fuel costs, widespread banditry, and insurgency, have significantly destabilized the region’s food systems. The likelihood of a major food system shock remained high through 2024.

The study has proposed several solutions to address these challenges, including promoting drought- and flood-tolerant crop varieties, adopting climate-smart and precision farming practices, and expanding agricultural innovation. The suggested solutions were also to invest in functional irrigation systems, routinely desilting rivers and streams, and strengthening social safety nets.

Developing sustainable, climate-adaptive food systems that minimize environmental damage and promote long-term resilience were also suggested solutions.

Quadri emphasized the urgent need for coordinated efforts to protect vulnerable communities and build sustainable systems capable of withstanding future climate challenges. “There is a need for collective action to secure food systems for the 21st century and beyond,” he concluded.

Aquatic foods, sourced from inland and marine fisheries or cultivated through aquaculture, are vital pillars for global food security, poverty alleviation, and economic development. Across the world, millions of people depend on these aquatic food systems (AFS) for their livelihoods and sustenance. However, these systems are facing growing threats from human activities. Overfishing, habitat destruction, pollution, and the worsening impacts of climate change are placing unprecedented pressure on AFS.

The changing climate, marked by rising temperatures, ocean acidification, and extreme weather events, compounds these challenges. Without intervention, lower-income countries in Africa, the Indo-Pacific, and South and Southeast Asia stand to face the gravest risks by 2100. The consequences will affect nutrition, health, social structures, economies, and the environment. Ironically, higher-income countries contribute the most to greenhouse gas emissions and are projected to experience comparatively lower climate risks.

However, not everyone experiences these challenges equally. The harshest impacts of climate change fall on those who already live with inequality. Women, in particular, are disproportionately vulnerable due to their reliance on natural resources and the burdens of household, caregiving, and productive labor. Despite their critical role in AFS, women often lack the resources and opportunities to adapt, restrained by entrenched gender norms and power imbalances.

To tackle this challenge, a team of gender researchers carried out a study to understand how gender and other social identities shape the adaptive capacity of AFS. This initiative, spearheaded by WorldFish, the International Water Management Institute, and other CGIAR centers, including IITA, aimed to explore how women and marginalized groups respond to climate risks and build resilience.

The team developed a conceptual framework to map how climate stressors interact with gender and socio-economic factors, influencing AFS outcomes. A comprehensive literature review spanning 2017 to 2022 was conducted to capture the latest insights. The research also drew from global datasets, including the Illuminating Hidden Harvests project, to analyze participation in small-scale fisheries. Bangladesh, a leading aquaculture producer, was a case study to delve deeper into how women navigate and adapt to climate challenges.

Findings showed that women are central to small-scale fisheries and aquaculture economies, yet their contributions often go unrecognized. Addressing this invisibility is essential to achieving Sustainable Development Goal 14, which calls for the conservation and sustainable use of oceans and marine resources. For sustainable progress, the focus must shift towards empowering women and fostering resilience within AFS.

The study proposed several pathways for policy, research, and intervention. First, addressing power inequalities is paramount to drive meaningful change. Women need greater decision-making power over resource allocation and income. This can be achieved by involving both women and men in initiatives that enhance food security and diversify livelihoods.

Second, the value of women’s work across the aquatic food value chain must be acknowledged and documented. Gender-sensitive approaches should be integrated into project planning, supported by sex-disaggregated data to track progress and outcomes.

Third, research must continue to investigate the intersection of gender, climate change, and small-scale fisheries, amplifying the voices of local actors and reinforcing their role in shaping solutions. This inclusive approach ensures that communities actively participate in building sustainable, equitable, and resilient AFS.

As climate change continues to reshape our world, the resilience of aquatic food systems depends on scientific innovation and social transformation. According to one of the researchers, a Senior Scientist and Gender Specialist at IITA, Steven Cole,
“By addressing gender inequalities and embracing intersectional perspectives, we pave the way for a future where AFS thrive, communities prosper, and the oceans remain a source of life for generations to come.”
