Understanding long-term climatic variability is basic to wise management and conservation of biodiversity. We analysed temporal variations in the local rainfall, temperature, Normalized Difference Vegetation Index and the hemispheric El Niño-Southern Oscillation (ENSO), using the Southern Oscilla...

Promising environmental mechanisms to control malaria are presently underutilized. Water level fluctuations to interrupt larval development have recently been studied and proposed as a low-impact malaria intervention in Ethiopia. One impediment to implementing such new environmental policies is t...

By altering evapotranspiration and influencing how water is routed and stored in a basin, natural and agrarian ecosystems affect river flow. To quantify the impact of ecosystems on streamflow in two large river basins in Asia and Africa, simple statistical relationships were calculated, enabling ...

This paper predicts climate change pattern and outlines suitable adaptation strategies related to irrigated agricultural practices in Hakra Branch Canal Command (HBCC) of Pakistan. Climate change predictions were simulated using models perturbed with climatic data and A2 emission scenario. A bias...

1 Thermal behaviour of the variegated grasshopper, Zonocerus variegatus, was investigated in the humid tropical zone of southern Benin, west Africa, in the dry seasons of 1996 and 1998. In 1998, investigations included studies of a population of grasshoppers sprayed with an oil‐based formulation ...

Estimating the potential land resources suitable for irrigation and evaluating the possible impact of climate change on land suitability is essential for planning a sustainable agricultural system. This study applied a GIS-based Multi-Criteria Evaluation (MCE) technique to evaluate the suitabilit...

This study is a continuation of earlier work on apical dominance inTriplochiton scleroxylon K. Schum., aimed at the development of an early clonal selection test for branching habit and yield in tree improvement programmes. Decapitated plants of five to seven clones were treated with either: (i) ...

The growth and development of Clavigralla tomentosicollis Stäl (Hemiptera: Coreidae) and Maruca testulalis Geyer (Lepidoptera: Pyralidae) were studied under laboratory conditions using three cultivated Vigna varieties (IT84E‐124, TVu 1890, MRx 10‐85S) and one wild variety (TVNu 72) under a range ...
