Permanent international river basin organizations (IRBOs) come in many shapes and sizes, ranging from those which are mainly facilitative in nature to those empowered to act on their own. Although differences in IRBO types may have important impacts on transboundary water resources management, sy...

Cassava mosaic disease (CMD) seriously affects cassava yields in Africa. This study compared the spatial distribution of CMD using three independent surveys in Rwanda and Burundi. Geostatistical techniques were used to interpolate the pointbased surveys and predict the spatial distributions of di...

Mujica, N.Kroschel, J.Zebitz, C.[Latitudinal and altitudinal distribution and relative importance of the leafminer flies Liriomyza huidobrensis and L. sativae (Diptera: Agromyzidae) in low and highland regions of Peru.]Latitudinal and altitudinal distribution and relative importance of the leafminer flies Liriomyza huidobrensis and L. sativae (Diptera: Agromyzidae) in low and highland regions of Peru.

A GIS-environmental database with 5 arc minute (c. 10 x 10 km) resolution was combined with tree inventory data. Tree diversity, phylogenetic diversity (PD) and the two main compositional gradients were determined for 46 tree inventories. Akaike's information criterion and a data jackknifing proc...

In studies of 25 rangeland sites selected along the S.-N. bioclimatic gradient and on the main soil types in the Gourma (Sahel, Mali), herbage cover, standing mass and botanical composition were measured in relation to seasonality of grazing and grazing intensity. When different sites were compar...

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 wa...

This paper examines poverty and deforestation in developing countries as linked problems and focuses on policies that can favour poverty alleviation in forested regions. The paper encompasses two elements: analysis of the spatial coincidence between poverty and forests, and proposed policy option...


The spatial distribution of nematode populations and damage in roots of Nabusa (Musa AAA-group ‘Matooke’), Pisang Awak (Musa ABB) and Sukali Ndizi (Musa AB) three banana cultivars widely grown in Uganda, was investigated at three locations, each with a distinctive nematode population and composit...

Understanding what farmers need in potato varieties and assessing available genetic resources at the farmer and district levels is important for the conservation and improvement of potato in Ethiopia. A survey was conducted in six major potato growing districts representing different agro-ecologi...
