In recent years, farming section of South Khorasan Province faces different limitations such as increasing shortage of water resources and continuous reduction of weather showers.Considering consecutive droughts and water crisis in agricultural plain of the province, it is necessary to use water resources optimally and increase productivity of water shortage input. Comparison of water productiv...

The objective of the study is to explore the scope for water productivity enhancement in irrigated agriculture in India through: i] water control; ii] optimizing nutrient input to crop; iii] improving the quality and reliability of irrigation water; and, iv] growing crops in regions where climate is favourable. The study is based on data from three important river basins in India, viz., Indus, ...

the input-oriented data envelopment analysis was used to measure the water use efficiency and productivity indices of tehran over the period 2005-13. meanwhile, the correlation between water uses and regional economic activities was examined using the gross regional domestic product index. the results indicated that the total productivity was improved 1.8% and 1.68% aspect of technical efficien...

Agriculture accounts for most of the renewable freshwater resource withdrawals in Malawi, yet food insecurity and water scarcity remain as major challenges. Despite Malawi’s vast water resources, climate change, coupled with increasing population and urbanisation are contributing to increasing water scarcity. Improving crop water productivity has been identified as a possible solution to water ...

This paper deals with the construction, decomposition and comparison of water footprint time series in 40 countries and one aggregate macro-region, in the period 1995–2009. The analysis of the different “footpaths” allows us to investigate the possible causes behind the time evolution of water footprints in the various countries. We notice that the physical and economic impact of economic growt...

Increasing competition for water across sectors increases the importance of the river basin as the appropriate unit of analysis to address the challenges facing water resources management; and modeling at this scale can provide essential information for policymakers in their resource allocation decisions. This paper introduces an integrated economic–hydrologic modeling framework that accounts f...

a r t i c l e i n f o Keywords: Malmquist–Luenberger index Urban water utilities Greenhouse gas emissions Nonparametric productivity measurement The energy use and greenhouse gas emissions in the provision of urban water and sewerage services have become an increasingly important issue in recent times. However, the impact of negative externalities such as greenhouse gas emissions on the product...

BACKGROUND: While recognizing the economic obstacles that currently block widespread use, many concerned with improving agricultural productivity and food security in Sub-Saharan Africa (SSA) are focusing on fertilizer as a remedy for declining soil quality and stagnant yields. Some have suggested that SSA needs to increase fertilizer use from 9 to at least 30 kg/ha during the next decade. Othe...
