iii FOREWORD This report summarizes the results of a Collaborative Programme of a group of international development agencies – AfDB, FAO, IFAD, IWMI and the World Bank – to review the experience of agricultural water investment in sub-Saharan Africa to date and to identify the conditions for successful investment in sustainable, cost-effective agricultural water development. IWMI and the World...

Changes in irrigation water-use efficiency are related closely to agricultural development. Clarifying the driving factors of irrigation water-use efficiency change at different agricultural development stages is beneficial for buffering the contradiction between the protection of water resources and massive agricultural water consumption. It also has theoretical and application value when it c...

A real-time quantitative polymerase chain reaction (Q-PCR) assay was developed for detecting and quantifying Escherichia coli in water samples from agricultural watersheds. The assay included optimization of DNA extraction and purification from water samples, and Q-PCR amplification conditions using newly designed species-specific oligonucleotide primers derived from conserved flanking regions ...

Global food demand will strongly rise over the next decades, due to population growth, average income increases, and trends towards higher consumption of animal products. Agricultural and food production already account for 70 percent of total freshwater withdrawals in the world. In addition, future water demand from private households, industry and for environmental purposes will also rise. Ov...

We present water quality data from 58 coastal wetlands, sampled as part of a larger effort investigating effects of nutrient enrichment and habitat disruption in the Laurentian Great Lakes. Our sampling design selected sites from across a gradient of agricultural intensity within combinations of biogeographic ecoprovince and wetland hydromorphic type and captured a large range in water quality....

as an assessment method of the water resources, water poverty index (wpi) has become an available tool in water resources management. in particular, agricultural water poverty index (awpi) is an assessment tool for agricultural water in rural areas. during the past decades, mahidasht basin in kermanshah province has been declared by water policy makers as “forbidden” basin in terms of water exp...

Water footprint is defined as the amount of water consumed in production any agricultural or industrial produce. It accounts directly and indirectly for producing product. analysis helps planning optimum utilization sector which subsequently leads to sustainable management resources. This review paper provides a on Footprint estimation methodology its merit shortcomings, practical challenges wi...

This paper is discussed the Anhui agricultural industrialization using the method of principal component analysis. The indexes include per capita net income of farmers in Anhui province, non-agricultural employment rate, urbanization rate, the total power of agricultural mechanization, universal ratio of rural water, car villages, the proportion of industrial waste water by sewage treatment in ...

Synthetic polymer was exploited as water-superabsorbent hydrogel and helped to conserve water in the agricultural soil. The hydrogel polymers were synthesized the carboxymethyl cellulose (CMC) and starch in addition to SiO2 nanoparticles. Superabsorbent hydrogel polymer having 35% water retention ability was analyzed with three replicates. Hydrogel increased the water restoration capability of ...
