The production and publication of this book is intended to capture the successes and lessons learnt from the CBA-ECA project and to document the impacts of the Ecologically Critical Areas (ECA) management initiatives, key lessons and impacts, challenges faced and future direction for wise-use management of the ECAs in Bangladesh.
Cambodia’s Tonle Sap Lake, a globally important fishery and carbon store, is rapidly losing flooded forests to deforestation, wildfire, and invasive species. Since 2010, Conservation International has worked with Community Fisheries to restore these habitats through nursery planting, direct seeding, and assisted natural regeneration. The work has revived 10 gallery forest species, including six globally threatened species, while supporting biodiversity such as the endangered hairy-nosed otter and the return of the fishing cat after more than a decade without confirmed records in the area. The program also strengthens community stewardship, stores carbon, and creates income opportunities for marginalized communities.
Continued support is needed because communities face limited experience, resources, and large-scale degradation. CI works with them to improve restoration techniques, study tree ecology, and identify effective ways to recover this unique ecosystem before degraded areas are overtaken by invasive shrubs and weeds.
In 2011, Snake Island (Kalumpang Island) was declared a National Coastal and Marine Center for Research (NCMCR) through DENR Administrative Order (DAO) No. 2011-12 issued on November 3, 2011. The policy established the island as a model site for sustainable coastal and marine management and prohibited tourism and fishing activities. It also directed DENR bureaus and field offices to formulate the island’s operational plan and research agenda.
An initial resource inventory in 2016 recorded a mean hard coral cover (HCC) of 46.25%. However, a massive coral bleaching event later reduced HCC to 3.69%. In response, interagency biannual assessments were instituted to document recovery trends and identify disturbance indicators. The assessments integrated benthic surveys, fish visual censuses and seagrass and mangrove assessments in post-bleaching recovery surveys. With limited pressure from tourism and fishing, coral recovery was observed, with a nearly five-fold increase in HCC (16.89%) 10 years after the bleaching event.
As the World Heritage Convention celebrates its 50th anniversary in 2022, over 1100 sites around the world are recognized as World Heritage – places that are so valuable to humanity that there conservation has been deemed our collective responsibility. Yet many of these exceptional places face increasing pressure from diverse types of development projects within and around the sites. Assessing the impacts of such projects is essential to both prevent damage to World Heritage and identify sustainable options. This Guidance and toolkit explains the process for achieving these goals. Offering practical tips and tools including checklists and a glossary, it provides a framework for conducting impact assessments for cultural and natural heritage sites.
The Elsentasarkhai living laboratory is a permanent platform for testing dryland restoration solutions before wider investment and replication. Established in 2011 on 45 hectares at Mongolia’s dry steppe-desert steppe transition, it combines field research, multi-year monitoring, demonstration, training and knowledge exchange. Trials address drought, strong winds, shifting sand and limited water through 1 x 1 m straw checkerboards, revegetation, windbreak forest belts and cultivation of 21 rare and endangered native tree and shrub species. A 10-hectare moving-sand trial stabilized sand for three to four years when barriers were combined with revegetation. Managed by the Institute of Geography and Geoecology, the station has continued beyond the original UNDP-supported project, hosted 40+ research activities, including five international collaborations, and provided learning for researchers, students, herders and officials. Its lesson is simple: test locally, monitor over time, learn openly and scale only what works.
Mongolia’s saxaul (Haloxylon ammodendron) forests stabilize Gobi soils, reduce sand movement, store carbon and support biodiversity, yet browsing and trampling can suppress seedlings. Since 2020, the GEF-funded ENSURE project, implemented by the Government of Mongolia with UNDP support, has combined site-targeted livestock exclosures with paired fenced-unfenced monitoring and practical training for local officers and rangers. The 2023 assessment covered eight fenced and eight comparison plots in four soums; it measured tree density, regeneration, vegetation, biomass, carbon and CO2 storage. Some protected sites showed substantially more young saxaul, while others showed limited differences, proving that fencing must be targeted and evaluated rather than counted as restoration by area alone. By 2024, community-driven regeneration measures covered more than 400 ha, including a 300-ha exclosure in Shinejinst. The approach links natural regeneration, local stewardship and evidence-based scaling for resilient dryland landscapes.
Yaghnob National Nature Park was established in a remote mountainous region home to the Yaghnobi people, a community with ancestral ties to the area. The park creation shifted local land governance. Previously, pasture use was shaped by traditional ownership rights, long-term arrangements, and locally negotiated community practices.
Subsequently, park authorities control and allocate grazing areas through rentals, upending access for local, outside, and transiting herders. These changes fuel friction over access, trust, and decision-making. Community members are concerned grazing allocations lack environmental assessments or equitable access, while park staff must implement ambitious management plans in difficult terrain with limited experience.
In response, TNF supports a community-led advisory board. This voluntary, collaborative body connects locals, pastoralists, park staff, government authorities, and scientists to improve communication, strengthen coordination, resolve conflicts, and share conservation responsibilities.
Developing countries like Nepal heavily rely on biomass fuels, contributing to climate change and health problems. In seeking to mitigate climate change, electric cooking technologies have emerged as a viable solution to reduce greenhouse gas emissions and deforestation while improving household ambient air quality and public health. PEEDA launched this project to combat climate change and improve health. The communities and policymakers were sensitized to adopting clean and renewable energy for cooking. Technical demonstration, live cooking sessions and the radio jingles has been used in creating the demands of electric stoves. Over 900 households has been supported with electric stoves and compatiable cookware in the Baiteshwor Rural Municpality. For sustaining the use of stove, 11 local technicians has been provided electric stove repair trainings. Further at policy level, Municipal Energy Plan (MEP) for this municipality has been developed to include the adoption of electric cooking over the next five year
Local communities in Nusa Lembongan, within Indonesia’s Nusa Penida Marine Protected Area (MPA), have transformed their relationship with mangrove forests from resource extraction to community led ecotourism and conservation. Since 2006, the Coral Triangle Center (CTC) has supported this transition through capacity building and management assistance, enabling the community to establish a locally managed mangrove ecotourism programme that generates sustainable livelihoods while promoting conservation. Today, a village-based organization oversees tourism operations, habitat stewardship, maintenance, and waste management, with local people actively participating in conservation activities. As tourism has grown following the COVID-19 pandemic, the community has strengthened management by introducing scheduled canoe operations, transparent pricing and visitor education to improve tourism quality while safeguarding the mangrove ecosystem.
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.
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:
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.
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.
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.
