The amount and spatial distribution of deep drainage (downward movement of water across the bottom of the root zone) and groundwater recharge affect the quantity and quality of increasingly limited groundwater in arid and semiarid regions. We synthesize research from the fields of ecology and hydrology to address the issue of deep drainage in arid and semiarid regions. We start with a recently ...

Abstract Arid regions have deficient precipitation, understanding the sources and transportation of moisture for precipitation are crucial. This study examined major contributions global six arid regions, which classified as inland region (China-Mongolia) coastal (North Africa, West Asia, United States, South Africa Australia). Results indicated that, in originates mostly from ocean, is influen...

Nowadays, there is a large demand for nutrient-dense fruits to promote nutritional and metabolic human health. The production of commercial fruit crops becoming progressively input-dependent cope with the losses caused by biotic abiotic stresses. A wide variety underutilized crops, which are neither commercially cultivated nor traded on scale, mainly grown, commercialized consumed locally. Thes...

plants and arthropods are the main elements of biodiversity in ecosystems. in order to evaluate structural biodiversity of plants and arthropods in natural systems of arid land, a study was carried out in shirvan, mashhad and gonabad, three regions of razavi and northern khorasan provinces, iran. in each region, 10 areas of natural systems selected and sampling was done in these selected areas....

BACKGROUND Agrobiodiversity is said to contribute to the sustainability of agricultural systems and food security. However, how this is achieved especially in smallholder farming systems in arid and semi-arid areas is rarely documented. In this study, we explored two contrasting regions in Benin to investigate how agroecological and socioeconomic contexts shape the diversity and utilization of ...
