Guidelines for the application of IUCN Red List of Ecosystems categories and criteria
The IUCN Red List of Ecosystems is a global framework for monitoring the status of ecosystems. It is part of the growing toolbox for assessing risks to biodiversity and aims to support conservation, resource use, and management decisions by identifying ecosystems most at risk of biodiversity loss. The basis of the IUCN Red List of Ecosystems is the IUCN Red List of Ecosystems Categories and Criteria, a set of eight categories and five criteria that provide a consistent method for assessing the risk of ecosystem collapse. These Guidelines assist correct implementation of the IUCN Red List of Ecosystems Categories and Criteria by providing information on the development of the protocol and a detailed overview of the scientific foundations supporting the categories and criteria.

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.
Desarrollo sostenible, adaptación al cambio climático y OMEC en zona buffer del Parque Nacional Tamá
El PNN Tamá es una estrella hídrica que abastece sectores productivos y comunidades de varios Departamentos al nororiente de Colombia y Estados al occidente de Venezuela. La falta desarrollo local, el conflicto armado, así como el cambio climático y la variabilidad climática han generado presiones frente al uso del suelo en la zona aledaña del PNN Tamá. Como solución, desde Parques Nacionales Naturales de Colombia innovamos la producción local sostenible de sistemas agrofroestales de café, el monitoreo participativo de recurso hídrico y las alianzas para la gestión de recursos, con lo cual se han fortalecido las inversiones y procesos de relacionamiento con actores estratégicos en favor de la conservación de los servicios ecosistémicos que brinda el Parque. Adicionalmente, hemos apoyado la declaratoria de Reservas Naturales de la Sociedad Civil, rodeando y protegiendo al PNN Tamá con áreas protegidas privadas manejadas por las comunidades.
Siembra y cosecha de agua de lluvia frente a la sequía en la Microcuenca de Huacrahuacho
Esta solución se implementó en la microcuenca Huacrahuacho, ubicada en un ecosistema altoandino llamado Puna sobre los 3.800 msnm. Se diseñó frente a los problemas de sequía y disminución de fuentes de agua, durante la época seca, para el consumo humano y el uso agropecuario. Tuvo como objetivos: captar, almacenar e infiltrar agua y recargar los acuíferos; incrementar/mantener el caudal de los manantiales; generar un microclima con mayor humedad; y conservar la biodiversidad.
La qocha, palabra quechua que significa laguna pequeña, fue el centro de un conjunto de medidas que incorporan forestación, zanjas de infiltración, manejo de pasturas naturales y acequias colectoras o aductoras.
Gracias a estas medidas construidas por las familias y a nivel comunal, se cuenta con más agua durante las épocas de estiaje, lo que ha permitido la recuperación de pastos naturales para la producción ganadera y un cambio hacia un paisaje más húmedo con mayor biodiversidad y belleza paisajística.
Conservación de páramos y bosques altoandinos para recuperar la regulación hídrica en la cuenca
Los escenarios de cambio climático en la Región Piura, anuncian escasez en la oferta hídrica, lo cual afectará a la población tanto en la parte alta (comunidad) como en la parte baja de la cuenca (usuarios del agua para riego). La solución contribuye a mejorar la resiliencia a través de acciones de conservación en los bosques de neblina y páramos (ecosistemas de montaña eficientes en la retención de agua) en la Comunidad de Samanga, para lo cual cuenta con un Área de Conservación “Bosques de Neblina y Páramos de Samanga” y su respectivo Plan de Manejo Participativo. Asimismo, se ha mejorado la capacidad adaptativa a través de acuerdos entre la comunidad y los usuarios – regantes, los que contribuyen a la sostenibilidad de las acciones de conservación (incluyendo fortalecimiento de capacidades y de desarrollo sostenible). Con esto, se busca recuperar y mantener el servicio de regulación hídrica de la cuenca del río Quiroz, sobre todo la oferta de agua en la parte baja.Gestion résiliente des ressources en eau et sol au Burundi
Le projet applique des mesures d’adaptation dans les bassins versants vulnérables. Les ressources naturelles, telles que l’eau et le sol, sont gérées durablement afin de réduire l’érosion et d’améliorer les rendements agricoles. Des mesures d’adaptation « vertes », sans regret, telles que l’agroforesterie et le reboisement communautaire sont complétés par d’autres mesures telles que le stockage et la promotion de l’infiltration de l’eau de pluie et le travail de conservation du sol.
Un ejemplo de gobernanza y participación de pueblos y nacionalidades indígenas en el manejo de la Reserva de Producción de Fauna Cuyabeno, Ecuador
Las principales amenazas para la conservación de la RPF Cuyabeno provienen de las actividades petroleras, extracción forestal de productos maderables, caza ilegal, tráfico ilegal de vida silvestre, desarrollo agrícola bajo sistemas de monocultivos, expansión de la frontera agrícola y colonización.
El aumento de la visitación turística también es un reto que debe enfrentar la Reserva, ya que es un importante punto de ingreso hacia la Amazonía baja, y tiene interesantes valores naturales y culturales que son aprovechados con fines turísticos.
En términos socio ambientales, en la Reserva habitan 11 comunidades indígenas de cinco nacionalidades, con las que es necesario llegar a acuerdos relacionados con el acceso a la tenencia de la tierra y al uso sostenible de los recursos naturales del territorio. Esto representa un reto, pues se busca articular las visiones de manejo y conservación del territorio, entre estas comunidades indígenas y el Estado.

After more than 30 years of exploration and practice, the green development concept of harmonious coexistence between man and nature has been integrated into areas and processes of Xiamen’s economic and social development, making Xiamen’s practice a global example of excellence in NbS and a model for sustainable development of coastal cities.
Solutions and case studies
Building with Nature for safe, prosperous and adaptive coastlines in Suriname
The Building with Nature initiative increases resilience along 10 km eroding coastlines, combining civil engineering with mangrove rehabilitation to build safe and adaptive coastlines. During 2015 and 2016 8 sediment trapping units were built (~1 km) to stop erosion and support mangrove rehabilitation. Technical measures include sediment balance restoration by permeable dams and mud nourishments, alongside mangrove rehabilitation. Socio-economic measures are currently being developed.
Empowering community-led sustainable management of clean fresh water through Pride for ARA methodology
Watershed management is, at its root, a human behavior challenge. But where humans are often the source of such problems, they are also the solution. Rare trains local leaders to implement behavior change campaigns that inspire communities to adopt new norms for how they interact with nature. Rare empowers communities in Colombia’s most water dependent geographies to participate in the management of their watershed ecosystems so that they benefit from higher water quality and flow and reduce the risk of droughts and floods due to extreme weather changes.
Since 2013, Rare has built the capacity of 14 officials of one of the largest regional environmental authorities of Colombia, Corporación Valle del Cauca, to engage local stakeholders in protecting riparian areas and improving land use practices using the Pride for ARA approach. These farmers are inspired by the Pride campaigns and the offer of technical assistance to protect critical ecosystems for watershed resilience.
Implementation of EbA measures in the Nor Yauyos-Cochas Landscape Reserve
A pilot was implemented to underpin the incorporation of an EbA approach into the planning tools for natural protected areas. The necessary methodologies and tools were developed, the vulnerability assessment was completed, the specific areas and the measures to be implemented were identified, including the communal management of native grasslands, vicuñas management (a wild relative of the llama), the expansion and conservation of wetlands and the restoration of water infrastructure.
Mapping and Valuing Ecosystem Services for Integrated Management
Ecosystem services were mapped and valued in a participatory process that included designing spatially-explicit scenarios of future human uses throughout Belize’s coastal zone. To understand the implications of different development scenarios, the team used InVEST models to map future value of coastal protection, recreation, and fisheries services. The resulting Plan can help the people of Belize plot a wiser course for managing the incredibly valuable resources their ocean and coast provide.
Transboundary integration and enhancement of public transportation system in a National Park region
Public transportation offers in the transboundary (TB) National Park region of Saxon and Bohemian Switzerland were successfully enhanced in a way that conserves natural landscapes while enabling an intensive nature experience for visiting tourists. A broad alliance of representatives from regional politics, tourism, nature conservation, transport and local population created a transportation networking concept whose implementation led to a significant increase in passenger numbers.
Tourism as a driver for change
The Public Use and Recreation Program (PURP) addresses the problem of destructive recreational activities in Cabo Pulmo National Park. The Program provides guidelines to local tour operators to reduce negative impacts of tourism activities on the Parks’ habitats and ensures their economic sustainability. As a result limits on water sports practiced in the Park are set, which dramatically reduces the impacts on the reefs resulting from these activities.
Functioning watersheds in the face of climate change
This solution promotes the integrated management of coastal watersheds that drain into the Gulf of Mexico and the Gulf of California by aligning the investments of public and private agencies to address climate change impacts and coastal and marine conservation. It is the foundation for enduring cross-sectorial coordination and local participation to maintain and recover watershed functions that deliver ecosystem services, which benefit cities and rural communities.
Community-based Mangrove Conservation and Rehabilitation
Mangroves and beach forests provide coastal greenbelts that act as a protective buffer to sea level rise and storms. Moreover, they are particularly effective in mitigating global warming and rising carbon dioxide levels by capturing and storing carbon in both above- and below-ground biomass. On Panay Island, protection of remaining mangroves and rehabilitation of degraded areas is carried out by local communities and supported by local governments.
Water and fire management of a peat swamp forest
The solution recovered natural conditions and protects 3,900 ha of unique peat swamp forest ecosystem. The conservation of Melaleuca trees found in this forest type is a national priority because they buffer floods, recharge aquifers and provide habitat for endangered wetland species. About 25,000 people living in the park’s buffer zone benefit through the provision of clean water and small cultivated fish.
Contribution to improving the resilience to coastal erosion in Togo
Local communities in coastal areas were supported to face to erosion and coastal pollution through:
– Awareness raising on vulnerability to these threats;
– Reduction of the effects of coastal erosion on the city of Aného to ensure the integrity of the area and enable sustainable socio-economic development: refection of the west bank of the mouth of the Lake Togo, rehabilitation of the road along the shore and protection of threatened homes and riverside hotel infrastructure.Applying ecosystem-based disaster risk reduction (Eco-DRR) in Integrated Water Resource Management (IWRM) in the Lukaya Basin, DRC
The project targeted disaster and climate risk reduction as an integral part of an Integrated Water Resource Management (IWRM) process conjunctly taking place in DRC. Pilot ecosystem-based measures aimed to reduce soil/gulley erosion and flood risk in two sites (upstream and downstream) in the Lukaya Basin, while improving livelihoods and income. Capacity was developed locally and nationally on ecosystem-based measures and national advocacy on EbA/Eco-DRR was supported through IWRM.
The project took an Eco-DRR approach addressing hazards and vulnerability to reduce disaster risk. However, the project activities also addressed climate change adaptation through working with climate change impacts and people’s vulnerability to change through the ecosystem-based measures involved in IWRM. Thus these measures can be seen as both Eco-DRR and EbA, while the implementation framework was Eco-DRR.
Applying ecosystem-based disaster risk reduction through a ridge to reef approach
This pilot project aimed to demonstrate how ecosystem-based measures could mitigate climate hazards and reduce vulnerabilities in Haiti through a ridge to reef approach. It implemented revegetation and sustainable vetiver farming to reduce risk of erosion and inland flooding, revegetation of coastal forest to buffer against storm surges and coastal flooding and created sustainable and resilient fisheries to increase local resilience; it also improved capacity and supported national advocacy.
The project undertook an Eco-DRR approach by targeting hazards (flooding, storm surges and erosion) and vulnerability (due to unsustatinable management) and increasing disaster prepardeness (e.g. early warning) to reduce disaster risk. However, these hazards are climatic hazards and impacts that are increasing due to climate change and increasing peoples vulnerability to climate change. Therefore, the ecosystem-based measures in this project undertaken are also EbA.
Conservation and sustainable use of páramo ecosystems as a response to climate change in Tungurahua, Ecuador
The páramo – the typical moorland of the high Andes – is an important ecosystem as it provides key ecosystem services to local communities, especially regarding water regulation. Nevertheless, this ecosystem is under severe threat mainly due to overuse and climate change. With a projected reduction in annual precipitation in Tungurahua, it is ever more important to conserve the páramo ecosystem. The solution integrated climate change into planning and strengthened local management structures.
Green aeration corridors in Stuttgart City
In Stuttgart, important green belts and green divides stretch between the built-up settlement areas, mitigating the climate heat stress. Greenery now covers more than 60% of the area. Furthermore, over 39% of Stuttgart’s surface area has been put under the protection of nature conservation orders. Incorporating these as important features in a Land Use Plan along with green belt policy are the most promising areas of municipal influence in respect of their impact on urban climatology and climate protection.
The Tacaná Watersheds: Implementing transboundary water governance through local community ecosystem based action
Despite their great potential and strategic importance the watersheds of the Tacaná volcano are vulnerable both ecologically and politically. IUCN (through the Water and Nature Initiative, WANI) and partners therefore set up a demonstration project in these watersheds, which combined pilot livelihood projects (water, soil and environmental conservation) and bottom-up integrated governance of water resources management (freshwater ecosystem management).
Isar-Plan: Improving flood protection and recreational opportunities by redesigning the Isar
The project group “Isar-Plan” was initiated in 1995 to restore the Isar river in Munich from its artificial canal bed to a more natural shape and function in order to improve flood control, biodiversity and recreational opportunities. Construction started in 2000 and was finished in 2011 having restored 8km of river and costing 35 million euros.
Ecosystem-based erosion control in Azerbaijan
Pastures in the South Caucasus region are under pressure through unsustainable use and climate change processes. The GIZ Programme “Integrated Biodiversity Management, South Caucasus” inter alia implements and tests affordable solutions together with local communities, preventing erosion and managing the mountainous ecosystems in a sustainable way. Piloted measures include: stabilization of slopes and river beds, setup of hay-meadows, afforestation, orchard management and construction of a tree nursery.
Coastal Capital: Economic Valuation of Belize’s Reefs and Mangroves
“Coastal Capital: Belize” addresses threats to Belize’s coastal ecosystems such as unchecked coastal and tourism development and overfishing – by assessing the contribution of reef- and mangrove-associated tourism, fisheries, and shoreline protection services to Belize’s economy. Our results were used to justify new fishing regulations, a successful damage claim against a ship that ran aground on the Belize Barrier Reef, and a ban on offshore oil drilling.
Medmerry Managed Coastal Realignment
In response to increased coastal flood events and resulting damages, the Environment Agency of the United Kingdom delivered a GBP 27 million project to realign the defences inland, providing significantly improved flood defences to allow for managed flooding. With the help of IUCN, a full assessment against the criteria and indicators of the IUCN Global Standard for Nature-based Solutionsᵀᴹ was conducted. The Medmerry managed coastal realignment is considered a strong Nature-based Solution. The building blocks of this solution highlight insights from some of the assessed criteria.

Solutions and case studies
Spelt as Surrogate Habitat for Grassland-Dependent Wildlife Species
The project addresses the dilemma of finding an economically viable grain crop that would not sacrifice food production for wildlife/biodiversity benefits. With the use of the non-GMO grain crop, spelt (Triticum aestivum subsp. Spelta), an alternative vegetation type on land can aid and maximize habitat value for rare grassland species and increase biodiversity on the landscape while also providing the producer with an economical food crop. The project results indicate that biodiversity increased and from an agricultural standpoint spelt was a more economical crop than hay.
Using a weed relative to turn tree tomato resistant to drought and diseases
Solution is undertaken using scientific fruit plant propagation and conducting innovative top-wedge grafting of (tree tomato) tamarillo (Solanum betaceum) terminal bud stick scion into its poisonous wild relative bug weed rootstock tolerant to drought and resistant to soil borne diseases and pests as well as having longer roots than tamarillo and stronger ones. Both plants belong to Solanaceae plant family, hence grafting the two plants is compatible and methodology transforms bug weed (Solanum mauritianum) as required. This innovation has therefore created food, agriculture and economic opportunities by using grafting methodology to transform the poisonous bug weed into agro biodiversity resources problem globally. Innovation is expected to contribute to feeding the ever growing world population that is expected to be nine billion by 2050.
USING BIOINTENSIVE AGRICULTURE TO IMPROVE NUTRITION, INCOME AND FOOD SECURITY
The concept of food and nutritional security refers to the ability of all people at all times to have physical and income access to sufficient, safe and nutritious food to meet their dietary needs for an active healthy life. It requires food being available enough, stable and accessible; without which inevitably leads to malnourishment that hinders individual performance.
Any enhancement of the food security calls for farmers’ sensitization and encouragement to adopt strategic methods that will not only cater to food and nutritional security but also income at a household level and sound management of the environment.
Climate change will affect availability, stability, utilization, and access to food security …(UN-ESCAP: Agriculture and Food Security, Asia)
When we farm in a way that maximizes the amount of carbon captured in our crops, and we return as much of that carbon as possible to the soil, we can effectively remove carbon dioxide from the atmosphere and store it in the soil.
