Dickens, Chris[Ecosystem services mapping as a framework for integrated resource management]Ecosystem services mapping as a framework for integrated resource management

Climate change is expected to exacerbate the already serious challenges to food security and economic development; especially on the African continent where people are already struggling to meet challenges posed by existing climatic variability. Change in temperature caused by climate change is c...


Kroschel, J.Tonnang, Henri E.Z.Juarez, H.Le Ru, B.P.Hanna, R.[Analysing climate impacts on insect pests using Phenology Modelling and GIS implemented in the ILCYM Software.]Analysing climate impacts on insect pests using Phenology Modelling and GIS implemented in the ILCYM Software.

Wetlands can only be well managed if their spatial location and extent are accurately documented, which presents a problem as wetland type and morphology are highly variable. Current efforts to delineate wetland extent are varied, resulting in a host of inconsistent and incomparable inventories. ...

Multifunctional soil conservation strategies have the capacity to control soil erosion as well as increase its quality, thus leading to sustained yields as long as planners have knowledge on the severity of soil loss. A comprehensive methodology that integrates Revised Universal Soil Loss Equatio...


Kabirigi, M.Mugambi, S.Musana, B.S.Ngoga, G.T.Muhutu, J.C.Rutebuka, J.Ruganzu, V.Nzeyimana, I.Nabahungu, N.L.[Estimation of soil erosion risk, its valuation and economic implications for agricultural production in western part of Rwanda]Estimation of soil erosion risk, its valuation and economic implications for agricultural production in western part of Rwanda

Maize (Zea mays L) is cultivated under a broad range of climatic conditions in West and Central Africa (WCA). For the purpose of germplasm evaluation, maize researchers in the subregion loosely stratified the diverse environments into four agroecological zones based on their knowledge and experie...

Cassava viruses are the major biotic constraint to cassava production in Africa. Community-wide action to manage them has not been attempted since a successful cassava mosaic disease control programme in the 1930s/40 s in Uganda. A pilot initiative to investigate the effectiveness of community ph...

Maps of abiotic stresses for rice can be useful for (1) prioritizing research and (2) identifying stress hotspots, for directing technologies and varieties to those areas where they are most needed. Large-scale maps of stresses are not available for Africa. This paper considers four abiotic stres...

Geographic modelers frequently compare maps of observed land transitions to maps of simulated land transitions to relate the patterns in reference maps to the output from a simulation model. Pixel-by-pixel analysis of raster maps at a single resolution is useful for this task at a single scale, b...

The spatial distribution of surface and subsurface soil attributes is an important input to environmental modeling. Soil attributes represent an important input to the Soil and Water Assessment Tool (SWAT), which influence the accuracy of the modeling outputs. An ArcGIS-based tool was developed t...
