Face aux changements climatiques marqués par des irrégularités croissantes des pluies dans le temps et dans l'espace, l'intensification de la production agricole dans les terres inondables s'impose. Au vue de ces possibilités qu'offrent ces zones humides, les bas-fonds sont aménagés dans le cadre des politiques nationales de développement de l'agri...

Cet article analyse les recompositions de pouvoir autour des modes d’accès aux ressources naturelles depuis le« boom aurifère » de 2004 dans la commune de Kampti, région du Sud-Ouest du Burkina Faso. Il se base sur des recherches documentaires et des données empiriques sur l’accès aux ressources naturelles, collectées dans la commune de Kampti, ent...

Reduction of natural vegetation cover in the savannah of West Africa constitutes a pressing environmental concern that may lead to soil degradation. With the aim to assess the degradation of natural vegetation in the savannah of Burkina Faso, this study combined NDVI trends and fractional Land Use/Cover Change (LULCC). Fractional LULCC maps, derive...

Our paper aims to analyze the modalities of coordination among local actors who are involved in integrated water resources management. So as to understand the dynamics of territorialization, we ground our analysis in the proximity framework to highlight that social and spatial relations around water resources are unbalanced. How this spatial inequa...

Lowland water resources management represents a challenge of the future that calls any commu- nity. Irrigated crops are grown in some areas of Burkina Faso, others are limited by a lack of irri- gation infrastructure. Due to limited crop irrigation, crops and the associated populations depen- dent on them, depend on rain and on climatic factors. Th...

Accurate quantification of land use/cover change (LULCC) is important for efficient environmental management, especially in regions that are extremely affected by climate variability and continuous population growth such as West Africa. In this context, accurate LULC classification and statistically sound change area estimates are essential for a b...

A comparative analysis of the sensitivity of NDVI and EVI to rainfall indicators has been carried out for different land use/covers in the Southwest of Burkina Faso. Three classified land use/covers maps for 1999, 2006 and 2011 were produced and change detection was applied to locate persistent areas. Thereafter monthly vegetation indices of plots...

West African Sahel suffered negative narrations about its environmental dynamic since the 1970s drought. Many conducted researches were mainly based on drivers and impacts of ecosystems degradation. Despite some ethno-botanic studies on environment dynamic in the Sahel area of Burkina Faso, there is a gap of knowledge on farmers’ perceptions. Using...

Environmental change in the Sudan-Sahel region of West Africa (SSWA) has been much debated since the droughts of the 1970s. In this article we assess climate variability and environmental stress in the region. Households in Senegal, Mali, Burkina Faso, Niger, and Nigeria were asked about climatic changes and their perceptions were compared across n...

Like many other cities in Sub Saharan Africa, Pouytenga in Burkina Faso has sanitation problems characterized by poor public health. Pouytenga is located upstream of the dam of Yitenga, and the pollution of this city is drained into this dam, which is used to supply drinking water. The city has no strategic sanitation plan. So, the objective of the...

Works of conservation of water and grounds and sorghum output in the Northern Center of Burkina FasoFace to the degradation of their vital spaces, the populations of Burkina Faso in general, area of Dem in particular became aware of the need for damming up the plague. They have, only or with the support of techniques of the State, the projects and...
