“…Initiated in 2003 by the feasibility study on land and ecosystem accounts conducted by the European Environment Agency (J.-L. Weber & European Environment Agency, 2006), the ENCA approach developed by Jean-Louis Weber is in line with a perspective that favours the safeguarding of natural capital. The ENCA quick Start Package published by the Convention on Biological Diversity in 2014 (Weber, 2014) to assist countries wishing to carry out ecosystem accounting. In addition, the approach is recognised by the United Nations Statistical Commission as fitting within the broad ecosystem accounting framework of the System of Environmental and Economic Accounts (SEEA).…”

“…It thus integrates an essential geographical element (the catchment area) and makes it possible to describe various variables such as the water resource and its accessibility on a territory. In order to produce it, the start-up manual of the Convention on Biological Diversity (Weber, 2014) proposes several methods. The one chosen for the Republic of Guinea consists in using the small river basins as the basic boundary of the units and assigning to them the dominant landscape type of land cover.…”

“…In ENCA, the objective is to diagnose the components of the ecosystem and thus to assess the impact of a degradation of the water resource on the whole ecosystem. The ecosystem water account is therefore an extension to the SEEA water accounts (Weber, 2014).…”

“…the water whose use by humans does not endanger the provision of the service by the ecosystem. One of the final calculations in the water accounts is the net accessible water surplus balance, which describes the exploitable water resource, taking into account potential limitations on use (Weber, 2014). Finally, as with the other accounts, the water accounts end with a table on the intensity of use index, which specifies the degradation (below 1) or not of ecosystems.…”

Abstract. Over the past thirty years (Rio Conference, 1992), the climate has become an important issue in world politics. With the Kyoto Protocol (1997), atmospheric carbon accounting has gradually been introduced with the aim of raising awareness of national and international decision-making systems for the implementation of an energy transition. However, this carbon approach does not take into account ecosystems despite their fundamental role in climate regulation. A global assessment of all natural resources and ecosystem services, known as natural capital, is necessary from a sustainable development perspective. This assessment must then be taken into account in national accounting systems. The aim of this article is to test, on the national territory of the Republic of Guinea, the ecosystem-based natural capital accounting method developed by Jean-Louis Weber (Weber, 2014). Based on three accounts (ecosystem infrastructure, ecosystem carbon and water resources), this method aims to measure the sustainable capacity or 'sustainability' of ecosystems to provide services. Based on land use & land cover layers produced in the framework of the agroecological zoning project (Jaffrain et al., 2021), we have operationalised this ecosystem accounting methodology in the Republic of Guinea to calculate the total sustainability of the ecosystem. The land cover layers are the basic structural data for monitoring and describing the evolution of the territory at different temporal intervals. Thus, several environmental indicators were defined from these combined geospatial data and eventually allowed to define the evolution of the total sustainability of the territory's ecosystem between 2005 and 2015. A clear degradation of this sustainability value was identified, which reflects the numerous land use changes affecting the country in the recent period (2005-2015).

West Africa, already highly influenced by the negative effects of climate change, is additionally characterized by rapid population growth, endemic poverty, and insecurity. This is affecting the natural capital of its ecosystems and the services they provide. Natural capital accounting (NCA) provides the fundamental evidence base required for informing economics and environmental decisions, thus strengthening the conservation and management of natural resources. The objective of this study is to showcase the development and evaluation of a semi-automated NCA platform (Sys4ENCA) designed to support decision making in the context of protected areas management in a multi-level example in western Africa. The accounting results highlight that simulations at the broader scale using national public data show that the natural capital of ecosystems in western Africa depends strongly on the mean climate and its variability. Evaluating regional datasets, the simulation with the platform shows that pressure on land in combination with weak governance reduces the capability of the ecosystem to deliver the required services in a sustainable manner, i.e., in the eastern part of the Bafing-Falémé landscape, where mining and intensive agriculture are fueling loss of natural capital. The results of Tier-3 accounting using local datasets enhanced the spatial variability and highlighted additional hotspots of degradation compared to the regional results, i.e., the prospective construction of a hydro-electricity dam (Koukoutamba) in the southern part of the Moyen-Bafing National Park located in the Bafing-Falémé landscape. The Sys4ENCA platform, combined with a multi-level approach, showed itself to be a valuable tool to facilitate protected area management as it provides not only consolidated information at a local scale but also the broader context and external pressures, i.e., climate change and demand for land. Given its automatized nature, the platform reduces human errors and increases the efficiency, speed, and harmonisation of computation over long timeframes and spatial scales.
