Étude des interactions entre services des écosystèmes : conséquences de la création des marchés ruraux de bois énergie sur un socio-écosystème au Niger

This paper aim to analyze the consequences of the creation of firewood rural markets in Niger. We made an assessment of the changes of interactions between ecosystem services linked with the creation of rural market. The study was based on interviews conducted at the local scale of the rural market of Ninpelima in order to assess the changes between 1980 and 2009. We define ecosystem services as an interaction between a social system and an ecological system. This definition allows us to characterize ecosystem services and the origins of their interactions. The synergies and trade-offs observed are the results of two types of interactions between ecosystem services: cooperation and competition. Rural markets rely on institutional and technical innovation at the national scale. These innovations affect the local scale. Although the creation of rural market aims essentially the service of firewood production, the interactions lead to changes of other ecosystem services. Management strategies have to take in account these interactions for that rural markets of firewood achieve their objective of sustainable management of the ecosystems as a whole.
