IN an earlier publication (Deuchar & Dryland, 1964) it was reported that a-methyl-norvaline, an amino acid described by Ross et al. (1961), whose structure resembles that of both valine and leucine (see below), caused a visible reduction in the quantity of haemoglobin formed by explants of the area vasculosa of the 48-hr, chick embryo, as compared with controls explanted without the analogue pr...

and DSSAT could be used to predict success or failure of soybean in dryland crop rotations. But for a crop The Root Zone Water Quality Model (RZWQM) and CROPmodel to be a valuable aid in predicting the effects, and GRO-Soybean simulate soybean [Glycine max (L.) Merr.] growth, success or failure, of intensifying and diversifying rotadevelopment, and yield. The models require calibration for soyb...

Abstract. The clearing of trees and native vegetation over the past 160 years has caused deep drainage to groundwater in the Broken Plains area. Predictions are that continuing recharge will bring the water-table to within 2 metres of the surface over the next 30 years. This will lead to water-logging and dryland salinity. A solution is to introduce deep-rooted perennial species such as lucerne...

Dryland forest resources have great socio-economic and ecological importance in countries of SSA by playing significant roles in livelihood diversification of both rural and urban households, wood and food security, providing animal feed, human health care and environmental conservation. Despite their great importance, these resources have been subjected to severe degradation, owing to several ...

Investment in natural capital restoration is increasing as a response to the widespread ecological degradation of dryland forests. However, finding efficient mechanisms to promote restoration among private landowners is a significant challenge for policy makers with limited financial resources. Furthermore, few attempts have been made to evaluate the costs and benefits of restoration interventi...

Clustering was used to divide dryland farming areas in western Iran into homogeneoussub-regions to identify dryland farming potential, considering drought impacts. Clusteringutilized eight algorithms/four indices to detect optimal number of clusters. Ward’s algorithmvalidated by Silhouette index, produced the best result by detecting 7 dryland farming clusters.Based on similar P/ETo values, fou...
