This paper uses a meta-Malmquist index for measuring productivity change of the water industry in England and Wales and compares this to the traditional Malmquist index. The meta-Malmquist index computes productivity change with reference to a meta-frontier, it is computationally simpler and it is circular. The analysis covers all 22 UK water companies in existence in 2007, using data over the ...

In this research, the effects of irrigation with saline and fresh water through drip irrigation method and using two irrigation management strategies: M1, M2 (M1 is irrigation with fresh water in alternative with saline water, M2 is saline water in first half time of each irrigation event and fresh water in the second half), on the yield, water productivity (WP), soil salinity, plant height...

low cereal and legumes yields and their rwp index are mainly due to poor distribution of rainfall and poor agronomic management practices. rainfed barley yield and rain water productivity (rwp, defined as rainfed grain yield divided by the total crop season annual rainfall water) in the dry farming are considerable by topography and latitude. yield data, rainfall, altitude and latitude of 182 p...

Increasing productive water use in agriculture is seen as paramount to meet future food demand with limited supplies. The main objective of this paper gain a better understanding the interrelated linkages between crop productivity (CWP) and applied (AWP) affected by irrigation management decisions order assess impact economic decision making on CWP AWP under area-limiting water-limiting conditi...

Key-words: extraction, watershed management, ecosystem services Water productivity (WP) metrics have proven useful in comparing production efficiency of various crops. Recently, it has also been proposed to facilitate more equitable allocation of scarce freshwater resources between irrigated agriculture and fisheries. Parameterizing water productivity metrics, however, proves to be very difficu...

Water stress adversely impacts many aspects of the physiology of plants, especially photosynthetic capacity. If the stress is prolonged, plant growth, and productivity are severely diminished. Plants have evolved complex physiological and biochemical adaptations to adjust and adapt to a variety of environmental stresses. The molecular and physiological mechanisms associated with water-stress to...
