The SYNERGI project, implemented from March 2023 to September 2025, aimed to promote urban community involvement in co-creating Socially Inclusive Edible Urban Green Infrastructure (IVUCs) in Maputo and Xai-Xai, Mozambique. The project successfully established IVUCs in six selected schools, increasing food production and educational opportunities. The project highlights the need for better institutional frameworks to support green infrastructure development.

A 2025 comparative analysis examines agricultural, economic, and biodiversity policy across Cameroon, Kenya, and Colombia in the context of agricultural expansion, using discourse analysis of policy documents via the Nature Futures Framework and Life Frames Framework, an evaluation of budgets allocated to major agricultural and biodiversity policies, and stakeholder interviews. It finds a shared struggle across all three countries to harmonize agricultural development with biodiversity conservation despite differing institutional capacities, historical pathways, and sociocultural contexts, with agriculture continuing to dominate policy agendas and resource allocation even as recognition of biodiversity's importance grows. Nature is framed primarily in instrumental terms, most strongly so in Colombia's utilitarian "Nature for Society" orientation, with intrinsic and relational values rooted in Indigenous cosmologies weakly reflected in implementation; funding for biodiversity-related ministries remains minimal relative to agriculture in all three countries — Kenya's environmental budget rarely exceeds 0.3% of national expenditure, with Cameroon showing similar disparities and Colombia's allocations continuing to favor agricultural expansion — and institutional fragmentation further undermines this governance.

A study in Bahir Dar, Ethiopia examined the integration of urban agriculture (UA) and green infrastructure (GI) through surveys and interviews with 99 stakeholders, supplemented by participatory observation. The main barriers to integration, based on multiple-response data, were a lack of supportive policies and regulatory frameworks (87%), limited awareness (57%), and space constraints (51%). Multicriteria decision analysis ranked integrated practices as the most effective strategy (score 16.81), followed by edible tree planting at garden centers (16.18), small gardens (13.83), and fence-edge greening (11.46). Structural equation modeling identified thermal regulation and access to fresh food as critical factors for planning sustainable urban systems.

This study evaluated land cover change and its drivers using spatial and statistical analysis in 22 designated protected areas (PAs) across the tropical coastal regions of sub-Saharan Africa. Results indicated that food production is prevalent in these protected areas regardless of their designation, and forest loss occurred in most PAs, suggesting weak conservation. Population density was the most significant driver of land cover change, and only 15 out of 22 protected areas showed an increase in their total ecosystem service value.

In Ethiopia, urban agriculture faces significant challenges due to government disapproval of public land use for farming and difficulty in obtaining credit. A 1983 survey in Addis Ababa found that 17% of 1352 households produced their own food on less than 25 sq. meters, with 90% of non-farmers citing lack of land. Despite urban agricultural cooperatives demonstrating 70% higher member income, their lack of government legalization prevents access to loans for productivity improvement.
