Assessment of agro climatic resources and natural water supply of the Sanaa basin area

Abstract

The aim of the study is to study the possibility of obtaining agricultural products from non-irrigated lands in arid climatic conditions of mountain areas, depending on the natural moisture supply. The possibility of assessing the natural moisture supply on the basis of average long-term precipitation, conditional indicators of annual natural atmospheric moisture and the water balance equation is considered. However, with current hydrological knowledge of the Sanaa basin area in the absence of the necessary data for calculating the water balance of the productive soils, there is proposed the a methodology for assessment of components of water balance and calculation of natural moisture provision of arable landson the level of «black box» with an accuracy sufficient for assessment of land productivity under natural moistening and a possibility of intensification of dry farming.
