Abstract The imbalance between water supply and demand highlights the vulnerability of many people prospect an uncertain future for supply. This work aims to compare Urban Water Security Index (UWSI) with three other methodologies (percentage flow duration curve, Sustainability Indicator, accumulated data from Drought Monitor) municipality Guarabira, Paraíba, Brazil. results show security based...

The community dynamics of organisms that exhibit multi-scale responses to habitat change are poorly understood. We quantified changes in species diversity and the functional composition a waterbird over two iterations repeated transition, annual drying-down arid-region Lake Ngami, Botswana. used our data test three theoretical predictions: simplification bird time due reduction area concurrent ...

The Benanain Watershed is located in East Nusa Tenggara with an area of 3,181 km2 and divided into 29 sub-watersheds. itself eastern region Indonesia a unique climate condition called semi-arid. high rainfall intensity occurring short duration results large surface runoff erosion. Floods erosion semi-arid areas due to sensitive soils drought heavy extremely. This paper presents the application ...

Arid regions pose a serious problem for crop production by suppressing plant growth. The use of plant growth promoting rhizobacteria (PGPR) as bioinoculant may be promising to enhance the crop yield in arid conditions. In the present investigation, four strains of cultivable bacteria associated with the rhizosphere of Saccharum L. grown in arid region were isolated using N-free media. Assessmen...
