Evidence for Nature-based Solutions: How Five Countries Built a Regionally Owned Environmental Database for Lake Victoria
Lake Victoria, shared by five East African countries, supports over 45 million people through fisheries, water supply, and agriculture. Declining water quality, rising pollution, and the absence of a shared evidence base made coordinated basin management difficult. To address this, the Lake Victoria Basin Commission (LVBC), with GIZ support under the EAC4Nature project, developed the first-ever State of the Basin Report (SoBR).
The approach combines joint water quality sampling at 44 stations across three countries, consultations with all five Partner States – Burundi, Kenya, Rwanda, Tanzania, and Uganda, and integration of findings into the Lake Victoria Basin Water Information System (LVB-WIS).
The SoBR follows a five-year cycle as a shared baseline for planning, policy, and investment. It identifies Nature-based Solutions – wetland rehabilitation, reforestation, and catchment restoration – as the most cost-effective pathway to improve water quality and build climate resilience. All five Partner States endorsed the report.
Restoring Lake Hawassa: How Multi-Stakeholder Partnerships and Nature-Based Solutions reverse Catchment Degradation
In Ethiopia’s Rift Valley, Lake Hawassa faces accelerating degradation from deforestation, pollution, erosion and rapid urbanisation – pressures no single actor can address alone. This solution establishes an inclusive multi-stakeholder partnership uniting public authorities, private companies and civil society to protect the lake through coordinated catchment stewardship.
Guided by the Natural Resources Risk and Action Framework (NRAF) developed between 2015 and 2020, partners jointly assessed risks, planned actions and implemented nature-based solutions (NbS).
Key building blocks included:
- Creating a multi-stakeholder platform,
- Applying the NRAF,
- Joint planning,
- Ecohydrological restoration,
- Waste management,
- Public and private financing; and
- Monitoring.
The partnership is now fully government-managed, and the approach upscaled to federal guidelines for restoring, rehabilitating and protecting surface water bodies all over the country.
URUGUAY. Strengthening biodiversity and land conservation policies as pillars of sustainable development.
In Uruguay, against a backdrop of the loss of habitat critical to biodiversity, the degradation of vulnerable ecosystems and soils due to the intensification and expansion of livestock and agricultural activities, poor grassland management practices, and pollution of water bodies and wetlands, the project aimed to implement actions to strengthen systemic, financial, and institutional capacities for biodiversity conservation and sustainable land management, thereby improving the effectiveness and sustainability of the management of protected areas, associated productive lands, and human well-being. This was achieved through: the establishment of a regulatory, financial, and institutional framework for biodiversity conservation and land degradation neutrality; Implementation of biodiversity and land conservation measures at pilot sites; and Knowledge management, monitoring and evaluation, and learning, to promote dialogue between public and private stakeholders.
URUGUAY. Financial Incentives for Sustainable Production
The Uruguayan Ministry of the Environment, with support from UNDP and the GEF through the project “Biodiversity and Land Conservation,” issued a call for proposals on sustainable production to organizations of producers of goods and services. An open competition was held for non-reimbursable grants aimed at groups of producers with proposals that incorporate improvements in environmental sustainability based on the sustainable use of natural resources. The call for proposals included an affirmative action strategy, reserving 30% of the awarded grants for women-led groups, as well as giving preference to groups that include young people. A total of 7 groups were selected, divided into 3 priority areas: i) sustainable livestock production on pastures; ii) nature tourism on livestock ranches; and iii) sustainable agriculture and biodiversity conservation.
Climate-resilient Fodder Storage Infrastructure for Disaster Risk Reduction and Pastoral Adaptation in Mongolia
Mongolia’s pastoral communities are increasingly exposed to climate-related hazards, particularly recurrent droughts and dzud that cause severe livestock losses and threaten rural livelihoods. To strengthen climate resilience and disaster preparedness, the UNDP ADAPT Project implemented a climate-resilient fodder storage solution in Khovd, Zavkhan, Dornod and Sukhbaatar provinces.
The solution established and rehabilitated hay and feed storage facilities in climate-vulnerable areas identified through risk assessments using climate, vegetation and livestock mortality data. In total, 48 storage facilities were developed to improve emergency fodder reserves and ensure timely access to feed during harsh winter and spring conditions.
The intervention combines risk-informed planning, resilient infrastructure, local participation and institutional collaboration. It has improved herders’ adaptive capacity, reduced vulnerability to climate shocks, strengthened food security for livestock, and enhanced local disaster risk reduction.
Improving farm sustainable land management practices through direct farmer assistance, Ridge to Reef approach
In Seychelles, increasing developmental pressures are degrading land, forests and soils leading to a loss of ecosystem services carbon sequestration and the ability to combat climate change. In an effort to reverse these pressures and restore degraded land, the project: ‘A Ridge to Reef Approach for the Integrated Management of Marine, Coastal and Terrestrial Ecosystems’ (Ridge to Reef) has been working with farmers to improve their sustainable land management practices.
Funded by the Global Environment Facility (GEF) and implemented in partnership with UNDP, the ‘Ridge to Reef’ approach is an integrated management strategy for marine, coastal, and terrestrial ecosystems, focusing on the connection between land and sea to address environmental degradation.
In particular, the project has been working directly with farmers to improve their sustainable land management practices (SLM). Through direct farmer assistance these farmers have begun to shift their practices to improve ecosystem health and resiliency.
From Blanket to Precision: A Data-Driven Decision Support Tool for Site-Specific Fertilizer Recommendations in Ethiopia
Ethiopia’s smallholder farmers continue to face large yield gaps despite decades of fertiliser use and agricultural research investment. A key constraint has been blanket fertiliser recommendations: uniform rates applied nationwide without accounting for local soils, agro‑ecological conditions, or crop diversity. This one‑size‑fits‑all approach leads to systematic misapplication, with over‑use in some areas and under‑use in others. As a result, Ethiopian wheat farmers achieve only 35-45% of potential yields, while more than 60 years of agronomic research data remained fragmented. The Supporting Soil Health Interventions in Ethiopia (SSHI) project, co‑funded by BMZ and the Gates Foundation and implemented by GIZ with the Alliance of Bioversity International and CIAT, EIAR, and the Ministry of Agriculture, addressed this gap by developing Ethiopia’s first Site‑Specific Fertiliser Decision Support Tool. Using machine learning, the tool delivers localised fertiliser recommendations, validated across hundreds of farms.
Enhancing farmer resilience in Benin: Terra preta as sustainable and more effective alternative to expensive mineral fertilisers
A 2016 study found 90% of Benin’s soils, notably in Borgou, Alibori and Zou, have low to very low fertility, cutting yields and threatening food security. Volatile mineral fertilizer prices make inputs unaffordable without subsidies. Locally made biochar amendments such as Terra preta increase farmers’ resilience and cost less than half of subsidized fertilizer. Biochar, produced by pyrolysis of organic matter, corrects soil acidity and, when mixed with compost or fertilizer, forms Terra preta, which improves yields and carbon storage. GIZ’s ProSoil programme promotes Terra preta by turning corn cobs and cotton stalks into biochar using Kon-Tiki kilns, which burn pyrolysis gases to cut toxic emissions. Using local residues maintains soil organic carbon for 100 years and yields a positive emission balance. ProSoil backs LTA graduate startups and the women’s NGO AFVA, trains 2,226 gardeners and 30 startups in Terra preta production, but scaling is limited by low investment capacity and costly MRV for carbon markets.
Strengthen Resilience of Coastal Communities through Local Early Action Plan-Climate Change Adaptation
Strengthening Resilience of Coastal Communities through the Local Early Action Plan-Climate Change Adaptation (LEAP-CCA) is a community-driven initiative in Mabul Island, Sabah, aimed at reducing climate change vulnerabilities through practical adaptation measures.
Located within the Coral Triangle, Mabul Island is rich in marine biodiversity but highly vulnerable to sea level rise, coastal erosion, wave levels during monsoon and typhoon. These threats affect critical ecosystems, fisheries, tourism, and local livelihoods.
Through collaboration between local communities, government agencies, NGOs, and tourism operators, vulnerable resources were identified and targeted adaptation actions developed. These include rainwater harvesting systems, coral restoration, and improved tourism management. The initiative has strengthened community awareness, improved local participation in climate action, and enhanced the resilience of ecosystems and livelihoods.
Para el MAR: Strengthening MPAs Through Localized Approach to Achieving Philippines’ 30×30 Target
The MPA Support Network (MSN) is a multi-sectoral alliance established to strengthen and sustain the management of MPAs in the Philippines. In 2007, MSN launched the Para el MAR (PEM), a biennial national incentive mechanism that recognizes effectively-managed MPAs.
PEM has 4 categories: Outstanding Locally-Managed MPA, Outstanding Network, Outstanding NIPAS, and Best Mangrove Awards.
Contingents submit their assessment tools such as the MPA Management Effectiveness Assessment Tool, Network Effectiveness Assessment Tool, Management Effectiveness Tracking Tool, and means of verification for screening. Finalists present assessment findings and expert recommendations during the culminating activity which also serves as an avenue for benchmarking of best practices among MPA management bodies.
Since its establishment, PEM addressed challenges on effective MPA management and sustainable funding for long-term protection. MSN has witnessed an upward trend in effective MPA management in the country especially among repeat contenders.
