Fortalecer la gobernanza para la AbE en la sub-cuenca compartida del río Sumpul (El Salvador-Honduras)

Los derechos de uso y la escasez de agua han causado conflictos en la cabecera de la subcuenca del Rio Sumpul (867 km2), compartida entre Honduras y El Salvador, lo que hace que, bajo un escenario de cambio climático, sea crucial la búsqueda de soluciones integrales que generen paz, desarrollo transfronterizo y resiliencia.

La gobernanza para la adaptación permite avanzar en esa dirección, promoviendo el trabajo multidimensional (multinivel y multisectorial), participativo, flexible y ecosistémico. Así, buscando el uso sostenible del agua como necesidad de adaptación en Sumpul, se reforzaron estructuras existentes de gobernanza, ampliando su representación, conocimientos y capacidad de gestión. A través del Comité Comunitario Binacional, se logró construir una agenda común basada en la construcción de confianza, diálogo y articulación de los actores de la cuenca alta. La agenda consideró la implementación de sistemas agroforestales y la conservación de suelos y fuentes de agua.

Integrating Photovoltaics with Water Retention and Ecological Restoration in Arid Regions

This solution demonstrates how large-scale solar energy development can be aligned with nature-based solutions (NbS) to address land degradation, water scarcity, and climate resilience. Implemented in Yulin, Shaanxi Province, and Yinchuan, Ningxia Province, the projects integrate photovoltaic infrastructure with ecological restoration and water retention strategies, transforming degraded sandy land into multifunctional landscapes.

Beneath the solar panels, water-retaining agents are incorporated into the soil to form distributed “micro-reservoirs” that capture limited rainfall, reduce evaporation, and support vegetation growth. The resulting vegetation has shown strong establishment compared to typical solar farm conditions. This improved vegetation cover enhances soil stability, reduces desertification risks, and strengthens ecosystem resilience, while maintaining efficient energy production with reduced cleaning frequency and lower water demand.

Revitalization of water and wet habitats in SRP Obedska bara

The project idea of was to revitalize and manage the wetland habitats in the Special Nature Reserve “Obedska bara” by implementing a nature-based Solution (NbS), namely through extensive grazing by a herd of water buffalo. Managed by a local farmer, and in cooperation with the protected area manager (Public Enterprise Vojvodinašume) and the BirdLife partner (Bird Protection and Study Society of Serbia), the problem posed by overgrown vegetation and reduced water flow was greatly reduced.

The main goal of the project was to clear up 25 ha of overgrown wet meadows, ponds, and forest edges by grazing water buffalo and to remove invasive plant species, creating “open water mirrors” and attracting more birds to reside in the area. The project also conducted activities to strengthen and raise the awareness of the local community about the importance of preserving wetland habitats.

Restoring Degraded Lands: The Dry Valley Rehabilitation and Productive Use (DVRPU) Approach for Climate Resilience in Ethiopia

In Ethiopia’s lowlands, climate change, erosion and drought degrade land, cut yields and fuel conflicts among agro-pastoralists. The Dry Valley Rehabilitation and Productive Use approach under the global GIZ ProSoil programme integrates technical and socio-ecological measures to restore dry valleys, secure water and promote sustainable land use. The approach uses Water Spreading Weirs, Dry-Stone Measures and biological measures. Water Spreading Weirs span dry riverbeds to spread and slow floods, enhance infiltration, trap nutrient-rich sediments and improve soils and vegetation. Based on a traditional and administrative system, the approach follows 7 steps from satellite-based suitability mapping to participatory planning by user cooperatives, rehabilitation and productive use. GIZ, BMZ, Ethiopian agencies, research bodies and communities collaborated to build 110 Water Spreading Weirs and 205 Dry-Stone Measures in Afar with similar work in Somali and Oromia, restoring 55,500 ha of degraded land and supporting 6,000 people.

Developing a Sustainable Biochar Value Chain: A Business Model to Combat Soil Degradation and Enhance Agricultural Productivity

India’s growing population has placed immense pressure on agricultural lands, resulting in nearly 40 percent of India’s land being degraded, with 3.7 million hectares suffering from the depletion of soil organic matter and nutrients. Also, the access to subsidised but still expensive synthetic fertiliser is challenging for many smallholder farmers. Therefore, the use of agro-chemical alternatives has gained traction to support sustainable agriculture. Biochar (in combination with biological fertiliser) improves soil fertility, water retention, neutralises acidity in soils and acts as a long-term carbon sink. However, the very limited number of businesses currently engaged in market-oriented biochar production is partly a consequence of technological and infrastructural limitations. To support market expansion, community bioresource enterprises have been established in six districts of Maharashtra/India. The goal is to promote the use of biochar among small-scale and female farmers through a sustainable business model.

Sqba Community Adopts the Satoyama Initiative: Promoting Eco-Friendly Farming and Traditional Crop Conservation

The Sqba Community is located in a mid-altitude forest with abundant ecological resources. Once an industrial area for the Hrung tribe, the community now comprises 33% Atayal, alongside populations of Hakka, Minnan, and Mainlanders. Local industries center on agriculture, particularly fruit production such as persimmons, and tourism, featuring campsites, ecotours, fruit-picking experiences, cultural ecology guided tours, and DIY workshops that make use of local ecological resources. Under the Satoyama Initiative, the Taichung Branch of the Forestry and Nature Conservation Agency conducted resilience assessment workshops (RAWs) in collaboration with locals to identify and prioritize urgent needs, such as conserving traditional crops, promoting sustainable use of forest, river, and field resources, and leveraging ecological assets for income generation and marketing. The local government and agricultural technology departments also participated.

Natural measures for ecological Gradac

The Public Water Management Company “Srbijavode”, in cooperation with the protected area manager “Ecological Society Gradac” achieved significant ecological restoration and educational outreach in the Gradac River area. The project involved riverbed clearing by mechanically removing obstacles to river flow, such as large fallen tree trunks, stumps and over 3,500 m³ of sediment, to enhance river flow and restore ecological balance. PWC “Srbijavode” implemented bioengineering interventions by installing willow-wattle structures to provide a nature-based solution for preventing riverbank erosion along a pilot area of 150 m. Throughout the project, scientists from the Institute for Biological Research “Siniša Stanković” conducted biodiversity assessments to ensure minimal negative impact on the ecosystem and to highlight the Gradac River’s good water quality. The Ecological Society Gradac engaged with over 250 primary school students in the Valjevo area through educational workshops.

Green Pastures for Green Transition

The project focuses on restoring grassland habitats in the Special Nature Reserve (SNR) Kraljevac by providing the local community with thirty sheep, a solar powered shepherd’s hut and an electrical fence which shall all be used for controlled grazing over 16.5 hectares to prevent habitat succession and support species like the endangered European ground squirrel. Two hectares along Lake Kraljevac have been afforested with native trees such as pedunculate oak, white willow, and poplar. A monitoring system for the European ground squirrel population has been established in order to define the ecological corridors for the species.

Apart from creating favorable conditions for a stable European ground squirrel population, the provision of 30 autochthonous sheep benefits the local community, the local shepherds in particular, and ensures the involvement of the local community in the sustainable management of the critical grassland habitat, whilst enhancing public awareness of the importance of grassland ecosystem conservatio

Local voices, sustainable forests: Participatory landscape restoration

In many African countries, agricultural growth remains a key driver of development. Agriculture ensures food security and is a source of rural income and employment. However, most small farms suffer from low productivity due to soil degradation, a lack of inputs and knowledge of sustainable agricultural practices, and the effects of climate change.

In Côte d’Ivoire, these challenges are amplified by deforestation: forest cover has fallen from around 16 million hectares in the 1960s to 2.5 million today, weakening ecosystems and soil fertility while increasing rural vulnerability.

The Participatory Household-Level Restoration Plan (PPR) offers an inclusive approach where each household aligns its vision, needs, and priorities with forest restoration. By placing rural families at the heart of planning, implementation, and monitoring, the PPR promotes sustainable restoration.

Ceasing Harmful Coastal Construction Subsidies to Protect Biodiversity in the Surroundings of the Mrigadayavan Palace, Thailand

The Mrigadayavan Palace, built in 1924 between the beach towns of Cha-Am and Hua Hin, was the summer house of King Vajiravudh, who ruled until 1925. To prevent coastal erosion and protect this cultural landmark, The Marine Department of Thailand (Ministry of Transport) constructed groins, seawalls, and jetties along the beach near the palace. These rigid structures cost USD 8.4 million in subsidies.

National experts, partners, and the Biodiversity Finance Initiative (BIOFIN) of the United Nations Development Programme (UNDP) measured the impact of subsidies on ecosystems in Thailand. After the team found that rigid coastal structures had accelerated erosion instead of preventing it, they presented these results to the Department of Marine and Coastal Resources (Ministry of Natural Resources and Environment).

As a result, the Thai cabinet ceased subsidies for coastal rigid structures near the palace. Existing structures were replaced with nature-based solutions, restoring the ecosystem and protecting cultural heritage.

Diverse Culture Based on the Satoyama Initiative of Shuanglianpi Pond (Yilan, Taiwan)

The Shuanglianpi Settlement, located in the mountains of Yilan, is named after Shuanglianpi Pond. Known for once hosting a third of Taiwan’s native aquatic plant species, the area was designated as the “Yilan County Shuanglianpi WildlifeRefuge” in 2003 to protect its freshwater plants.

This designation and land expropriation led to longstanding conflicts among residents, public

sectors, and externalgroups. In 2018, the Yilan Branch of the Forestry and Nature Conservation Agency began interviewing local elders and residents, uncovering a shared memory: the damaged century- old irrigation canal. Most residents expressed support for restoring the canal torebuild relationships, foster communication, and establish a partnership basedon mutual support. To advance sustainable development, the Branch invited local partners to join resilience

assessment workshops (RAWs) in 2022 to identify priorities and formedan interdepartmental platform for ongoing adaptive co-management of Shuanglianpi.

Building community-led restoration capacity through an operational indigenous plant nursery

This Solution centres on establishing an operational indigenous plant nursery as part of an active restoration programme in the Grootvadersbosch landscape, South Africa. The nursery is used not only to propagate locally appropriate indigenous plants, but also as a practical training hub for community members involved in restoration.

The approach addresses key challenges including invasive alien plants, degraded riparian and forest-edge habitats, limited local restoration skills, and shortages of suitable planting material. By integrating training with hands-on nursery work and field implementation, the project has produced thousands of indigenous plants, restored degraded sites, and built lasting restoration capacity within the local community.

The new guardians of the páramo: Voluntary Agreements that transform the practices of farming families.

Chingaza National Park, with more than 77,000 hectares, is one of the most strategic protected areas of the Colombian National Natural Park System, as it is the main source of drinking water for 10 million people in the Bogotá DC and surrounding municipalities. It also protects moorland and Andean forest ecosystems that are key to regulating water resources in the Orinoco macro-basin, conserves endemic and/or nationally and globally threatened species of fauna and flora, and safeguards important sites for the indigenous communities that inhabited the territory. To guarantee its protection, the park has established conservation agreements with peasant families as part of a conservation pact. This participatory strategy allows communities to improve their productive practices while guaranteeing the protection of key ecosystems for the provision of ecosystem services, achieving a local collective effort that guarantees water security for future generations.
