1. Sequencing integrated soil fertility management options for improved crop productivity and nutrient use efficiency on sandy soilsMaintaining high use efficiency of nutrient resources available to farmers is key to sustainable intensification of African smallholder farms. Multi-locational on-farm experiments were conducted on degraded sandy soils (< 10 % clay) in eastern Zimbabwe over 4 cropping seasons to evaluate different manure-, fertilizer- and legume-based integrated soil fertility management (ISFM) options with respect to maize productivity and, fertilizer nitrogen (N) and phosphorus (P) use efficiency....

2. A Time Series Investigation to Assess Climate Change and Anthropogenic Impacts on the Degradation of Nile Delta, Egypt.Land degradation risk, status and rate in Nile Delta, Egypt were assessed for a time series using remote sensing data over the past five decades using TM, ETM and OLI. Quantitative deterioration of the area was produced based on the comparative study approach in the integrated weighted sum, weighted overlay and fuzzy model. Where degradation factors were compiled in a raster and each data set scored on a 1 to 5 (very low, low, moderate, high and very high scale). The data sets were then weighted... B. Abdellatif, M.R.
