Soil erosion in the West African Sahel: a review and an application of a "local political ecology" approach in South West Niger
Influence of vegetation pattern on the productivity, diversity and stability of vegetation: The case of 'brousse tigree' in the Sahel
Compilation of Geospatial Data (GIS) for the Mineral Industries and Related Infrastructure of Africa
This geodatabase reflects the U.S. Geological Survey’s (USGS) ongoing commitment to its mission of understanding the nature and distribution of global mineral commodity supply chains by updating and publishing the georeferenced locations of mineral commodity production and processing facilities, mineral exploration and development sites, and mineral commodity exporting ports in Africa. The geodatabase and geospatial data layers serve to create a new geographic information product in the form of a geospatial portable document format (PDF) map. The geodatabase contains data layers from USGS, foreign governmental, and open-source sources as follows: (1) mineral production and processing facilities, (2) mineral exploration...
Agriculture Intensification and Ecologically Sustainable Land Use Systems in Niger: Transition from Traditional to Technologically Sound Practices
This dataset is the second (circa 2000) in a series of three 2-kilometer land use land cover (LULC) time-periods datasets (1975, 2000, and 2013) aids in monitoring change in West Africa’s land resources (exception is Tchad at 4 kilometers). To monitor and map these changes, a 26 general LULC class system was used. The classification system that was developed was primarily inspired by the “Yangambi Classification” (Trochain, 1957). This fairly broad class system for LULC was used because the classes can be readily identified on Landsat satellite imagery. A visual photo-interpretation approach was used to identify and map the LULC classes represented on Landsat images. The Rapid Land Cover Mapper (RLCM) was used to...
Seasonal fluctuations in population densities of Bulinus senegalensis and B. truncatus (Planorbidae) in temporary pools in a focus of Schistosoma haematobium in Niger: Implications for control
Evidence of a dramatic decline of the red-necked ostrich Struthio camelus camelus in the Aier and Tenere National Nature Reserve, Niger
Variations in phenology of a residual invasive shrub species in Sahelian fallow savannas, south-west Niger
Yale stocks and flows database (YSTAFDB) describing anthropogenic materials cycles, recycling, and criticality for 102 materials on spatial scales ranging from suburbs to global and timescales from the early 1800s to circa 2013
This data release presents the Yale stocks and flows database (YSTAFDB). Its data describe the use of 102 materials from the early 1800s to circa 2013 through anthropogenic cycles, their recycling and criticality properties, and on spatial scales ranging from suburbs to global. This data collection was previously scattered across multiple non-uniformly formatted files such as journal papers, reports, and unpublished spreadsheets. These data have been synthesized into YSTAFDB, which is presented as individual comma-separated text files and also in MySQL and PostgreSQL database formats. Consolidation of these data into a single database can increase their accessibility and reusability, which is relevant to diverse...
