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.
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.
Integrated river restoration and community stewardship to protect the Critically Endangered Tradouw Redfin
This Solution applies integrated river restoration and community stewardship to reduce key threats to the Critically Endangered Tradouw Redfin in the Huis River, South Africa. It combines invasive alien plant clearing, targeted riparian restoration, water-saving measures and community awareness to improve habitat quality and river resilience.
The approach addresses habitat degradation, invasive vegetation, water pressure and limited local awareness. By restoring riparian structure and coordinating action through a multi-agency Tradouw Redfin Working Group, the project improved river health indicators, restored critical habitat and strengthened long-term protection for the species through a formal Species Action Plan.
Scalable Model for Sustainable Coffee Farming in Panama
In Panama’s western highlands, small coffee farmers face growing pressures from pests, plant diseases and climate change. Heavy reliance on chemical pesticides has harmed biodiversity, degraded soils and threatened pollinators. This solution shows how endophytic fungi, microorganisms that live naturally inside plants, can serve as effective biological pest control adapted to local conditions. Fungal strains were identified and transformed into low-cost formulations that were tested on coffee farms, where they significantly reduced the need for chemical inputs. The initiative brings together scientists, government institutions and local communities, with a strong focus on training and empowering women farmers. By addressing biodiversity loss, land degradation and gaps in technical capacity, the project strengthens sustainable livelihoods and climate resilience. Farmers benefit through higher yields, lower costs and healthier ecosystems, creating a scalable model for sustainable coffee production in Panama and beyond.
First Payment for Environmental Services Scheme in Cuba: Promoting carbon removal through sustainable forest management
Cuba’s geological evolution, climate, and insular geography led to highly diverse ecosystems with various endemic species. Nonetheless, declining forest cover and climate change hazards have threatened the country’s rich biodiversity. Moreover, CO2 emissions accelerate the impacts of climate change on ecosystems, in addition to harming human well-being.
To address these challenges, the Cuban government, with support from the Biodiversity Finance Initiative (BIOFIN) of the United Nations Development Programme (UNDP) and the Ecovalor project, established a payment for environmental services scheme that rewards carbon removal through sustainable forest management.
By March 2025, the scheme disbursed USD 238,000 (CUP 5,709,066) in payment for environmental services, associated with the removal of 999,473 tons of carbon across 12,646 hectares of forest. This initiative contributes to climate mitigation, ecosystem conservation, and the responsible use of natural resources in Cuba.
Guidelines for rewilding
These guidelines offer both a call for change and general guidance for users. The following five guidelines, adapted from the ten guiding principles for rewilding (Carver et al., 2021), provide a foundation for understanding and taking action to prevent further losses in nature, promote the recovery of biodiversity, and support the restoration of ecological integrity.
Applying the IUCN Global Standard for Nature-based Solutions™
The IUCN Global Standard for Nature-based Solutions™ was developed during a two-year process, aiming at setting a common basis of understanding for NbS, and providing a robust framework to design, implement, assess, adapt and improve NbS. The first version of the Global Standard for NbS has eight criteria and 28 indicators, and it was launched in 2020, supported by the IUCN Resolution 060.
To support the implementation phase of the NbS Global Standard, IUCN Commission on Ecosystem Management (CEM) carefully selected 21 case studies around, to analyse, learn from and showcase examples of NbS good practice; and explore in detail how the IUCN Global Standard for NbS can be applied in different contexts. The case studies’ authors were provided with the NbS Global Standard’s Self-Assessment Tool, and assessed how well their case study met the eight criteria and 28 indicators. The 21 case studies were implemented in a diversity of contexts across the globe and in different regions, in equally diverse types of biomes – ranging from marine and coastal, to freshwater, terrestrial (including polar alpine biomes, forest, woodlands and grasslands biomes) to intensive land use biomes (including three cities) – as well as in two business-related cases to illustrate how NbS can also be implemented in a business context.
Embedding Integrated Water Resources Management in Rwanda’s Sebeya Catchment
The Sebeya catchment in Western Rwanda, once prone to recurrent flooding, erosion, and landslides, was transformed through the “Embedding Integrated Water Resources Management in Rwanda (EWMR)” project. Led by Rwanda Water Resources Board and partners, the project applied Nature-based Solutions (NbS) to restore 7,700 hectares using terraces, trenches, riverbank protections, and afforestation. The approach combined land rehabilitation with innovative financing, value chains, and inclusive planning. Over 35,000 green jobs were created, alongside improved soil health, aquifer recharge, agricultural productivity, and livelihoods. By integrating community-driven land use planning into district-level governance, the project laid the foundation for long-term resilience and scalability.
The Green Project Model: Regreening Rwanda Bugesera for People and Nature
The Green Project in Gashora Sector, Bugesera District, Eastern Rwanda, transformed the country’s driest agro-ecological zone through regenerative, farmer-led land restoration. Facing severe land degradation, poor soil fertility, and widespread poverty, the project implemented agroforestry-based conservation agriculture using shrub-tree hedgerows, rotation cropping, and organic mulching. Designed as a low-cost, inclusive and replicable model, the project improved soil health, enhanced biodiversity, increased yields, and diversified household incomes. Starting with just six farmers, it now engages over 1,000. The intervention shows how Nature-based Solutions (NbS) tailored to local conditions can reverse degradation, boost resilience, and uplift rural livelihoods.
Community of women committed to preserving the Nosy Hara marine protected area
Nosy Hara National Park is part of Madagascar’s network of protected areas. A genetic reservoir of marine biodiversity, it is a sustainable fishing site par excellence, for the fishing community living around the park. Mangrove crabs, octopus and reef fish are the most commonly caught species. The Park is renowned for the production of octopus, fish for local, regional and even national consumption.
Overfishing in accessible areas by small-scale fishermen, the failure of nomadic fishermen to comply with fishing closures, and the lack of park staff for surveillance are among the daily challenges faced by park managers.
Co-management through the effective involvement of the local community in the preservation of the park is an approach adopted, particularly by the women’s community of the village of Ankingameloka, who actively participate in the co-monitoring of mangroves, the restoration of the ecosystem and the monitoring of fishermen’s daily catches.
