Brochure, flyer, fact-sheetExemplary valuation of natural resource assets and ecosystem services - Cold Winter Deserts of Central Asia 2022
Also available in:
Cold winter deserts (CWD) are biomes having annual precipitation below 100 mm, which occurs mainly in winter and part of spring of the year. The extreme temperatures vary between -45°C in winter and +50°C in summer. Many of these deserts are inland areas separated from oceanic moisture by mountain ranges. An example of this is cold winter desert lying somewhere between Northern Iran and Mongolia through Central Asia, with its enormous area of land masses overlying mainly (95%) on Central Asian countries. Despite harsh climatic conditions that prevail over the CWD of Central Asia, there are numerous benefits derived from these deserts that are crucial for livelihoods of the population living there. These benefits are derived in form of various ecosystem services from the CWD. This study was conducted under the Central Asia Desert Initiative (CADI) project, aimed at conservation and adaptive use of cold winter deserts in Central Asia. The objective of the study in Uzbekistan was to assess the value of natural resource assets and ecosystem services (ES) to proximate communities to create awareness of desert ecosystem’s importance (i.e., how natural resources and ES services or lack of them impact the quality of life for community stakeholders, particularly those reliant upon forest and rangelands for their livelihoods). -
Book (series)Valuation of marine and estuarine coastal ecosystem services in the Canary Current large marine ecosystem region / Évaluation des services écosystémiques marins côtiers et estuariens dans la région du grand écosystème marin du courant des Canaries 2020

No results found.Ecosystem valuation is a process that assigns a monetary value to the benefits that are provided by an ecosystem and its ecosystem services. This study carries out the economic valuation of marine and estuarine coastal ecosystem services in the Canary Current Marine Ecosystem (CCLME). The CCLME stretches along the coast of Western Africa, from Morocco to Guinea, and is characterized by high biological productivity due to the upwelling of deep, cold oceanic waters along this coast. This also supports a high abundance of fish resources (both pelagic and demersal) and overall high biodiversity. This study reviews and assesses ecosystem services provided by the marine areas, coastal mangroves and seagrass meadows. These coastal areas not only provide habitats for some commercial fish species, but also feeding grounds, nurseries, or refuges. Therefore, mangroves and seagrasses can play an important role in maintaining fish stocks. L’évaluation des écosystèmes est un processus qui attribue une valeur monétaire aux avantages offerts par un écosystème et ses services écosystémiques. Cette étude cherche à réaliser une évaluation économique des services des écosystèmes côtiers marins et estuariens dans l’écosystème marin du courant des Canaries (CCLME). Le CCLME s’étend le long des côtes de l’Afrique de l’Ouest, du Maroc à la Guinée, et se caractérise par une productivité biologique élevée due à la remontée d’eaux océaniques froides et profondes (upwelling) le long de cette côte. Cela favorise également une grande abondance de ressources halieutiques (pélagiques et démersales) et une biodiversité globale élevée. Cette étude examine et évalue les services écosystémiques fournis par les zones marines, les mangroves côtières et les herbiers marins. Ces zones côtières fournissent non seulement des habitats pour certaines espèces de poissons commerciales, mais constituent également des aires d’alimentation, de nourriceries ou des refuges. Par conséquent, les mangroves et les herbiers marins peuvent jouer un rôle important dans le maintien des stocks de poissons. -
Book (series)Economic valuation of ecosystem services provided by deep-sea sponges 2020
Also available in:
No results found.This report represents the first economic valuation of the ecosystem services provided by deep-sea sponges in the North Atlantic. It is based on information available in the scientific literature at the time of writing, but also indicates the research areas where discoveries and research advances are shortly expected. The report is aimed at a generic public with no specialized knowledge on sponges or on economic valuation. It is outlined in a way to provide essential background information, but makes reference to a comprehensive list of scientific publications for further insights.
