Opportunities for saving and reallocating agricultural water to alleviate water scarcity As water scarcity worsens globally, there is growing interest in finding ways to reduce water consumption, and for reallocating water savings to other uses including environmental restoration. Because irrigated agriculture is responsible for more than 90% of all consumptive water use in water-scarce regions, much attention is being focused on opportunities to save water on irrigated farms. At the same time, many recent journal articles have expressed concern that claims of water-saving potential in irrigation systems lack technical credibility, or are at least exaggerated, due to failures to properly account for key elements of water budgets such as return flows. Critics have also asserted that opportunities for reallocating irrigation savings to other uses are limited because any freed-up water is taken up by other farmers. A comprehensive literature and internet survey was undertaken to identify well-documented studies of water-saving strategies in irrigated agriculture, as well as a review of case studies in which water savings have been successfully transferred to other uses. Our findings suggest that there is in fact considerable potential to reduce consumptive water use in irrigation systems when proper consideration is given to water budget accounting, and those savings can be beneficially reallocated to other purposes.

Allocating total emission pollutant control based on water environmental carrying capacity: model establishment and case study Abstract
The determination of the total amount of water pollutant emission in different regions is a difficult problem faced by managers and researchers. Previous studies mostly focused on operability and fairness with little attention paid to local water quality. In order to make total emission pollutant control (TEPC) truly serve the improvement of water quality, a water total emission pollutant allocation model was built based on water environmental carrying capacity (WECC) in this paper. This model was used to construct a water pollutant emission control allocation scheme for 28 cities in Henan Province, China. The results showed that the chemical oxygen demand (COD) reduction rates for these cities ranged from 16.8 to 38.6% and ammonia-nitrogen (NH3-N) reduction rates ranged from 5.7 to 43.5% in 2020, which were different from the previous targets for these cities without considering their current status of water quality. The largest COD reduction rates for different types of point sources (industrial, urban, and large-scale livestock sources) were 35.4%, 39.0%, and 38.0%, respectively, and the largest NH3-N reduction rates were 62.2%, 42.5%, and 43.5%, respectively. This study solves the problem of long-term disconnection between TEPC and water quality improvement in China. The results can also be applied to implement the TEPC to improve water quality in other regions with a similar problem.

Impact of socio-economic and water access conditions on life satisfaction of rural farmers in Faisalabad district of Pakistan Abstract
The current study is designed to see the effects of water access on the well-being of the farming community in rural areas of Pakistan. The data were collected from 300 households of ten villages in rural Faisalabad, Pakistan where the population is facing serious water quality and access issues due to industrial pollution, lack of clean water supply system and limited access to fresh water for agricultural use. We employed ordinary least square and ordered probit methods to measure the association between water access variables and households’ well-being. We found that source and quality of drinking water, access to irrigation water, and percentage of crop water requirement fulfilled, and water expenses were statistically significant influencing the households’ well-being. The study concluded that water access conditions strongly influence the life satisfaction and water access conditions must be considered in future research. Acknowledging the contribution of village-level economic activities to economic growth, a strong policy is proposed to re-evaluate the existing rural water supply strategy to enhance the households’ well-being and enhance livelihood generation among neglected pro-poor farmers in rural areas of Pakistan.

A question on sustainability of drinking water supply: a district level analysis of India using analytic hierarchy process Abstract
The subject of drinking water supply falls under the legislative jurisdiction of the State governments in India. States have their own mechanism of drinking water supply through urban and rural local bodies. Drinking water supply itself is a multidimensional phenomenon of sources, quality, accessibility, sufficiency, etc. This study combines various aspects of drinking water supply at the district level, by assigning weights through analytic hierarchy process, to result in a drinking water supply index. The spatial pattern of drinking water supply index is not in favor of the areas having abundant natural water endowment. Areas which are low in the natural endowment of water are better in drinking water supply, while areas which have abundant natural water are not able to manage the available water and are low on the drinking water supply index. Among various socio-economic-political factors, water governance is most important in the wake of water supply being the function of urban and rural local bodies.

Factors influencing immigrants’ satisfaction in Danjiangkou Reservoir based on logistic regression model Findings from a prospective study of project-induced migration along the middle route of the South-to-North Water Diversion Project in China are reported. The study seeks to identify the key factors influencing differences in immigrants’ satisfaction, from their own characteristics, family income, production conditions, living conditions, social conditions, resource conditions, and environment, using Danjiangkou Reservoir as the case study area. A questionnaire survey data with a large sample (1,031 immigrant households in the Danjiangkou Reservoir) was used for the logistic model. Analysis indicated that variables such as immigrants’ family income, as in ‘per capita net income’; immigrants’ production conditions, such as ‘quality of cultivated land’; immigrants’ living conditions, such as ‘infrastructure’; and immigrants’ social conditions, such as ‘the implementation of immigration policy’ in the case reservoir model are the most important factors that affect the immigrants’ satisfaction. The degree of importance of ‘per capita net income’, ‘quality of cultivated land’, ‘infrastructure’, and ‘the implementation of immigration policy’ was 14.8%, 16.0%, 9.2%, and 8.1%, respectively. Considering the practical implications of this research, identifying factors affecting immigrants’ satisfaction with the reservoir resettlement relocation experience could be useful for policymakers designing immigration programs.

Water policy and regional economic development: evidence from Henan province, China Abstract
With the rapid advance of industrialization and urbanization and the intensified impact of global climate change, the contradiction between the global water shortage and economic growth has become prominent. This paper, taking Henan province as an example, analyzed the influence of water resource policy on regional economic growth through a calculable general equilibrium model and further discussed the relevant policy recommendations. The results showed that the improvement of water supply, water efficiency and water technology could promote the growth of the regional economy and result in a positive effect on regional GDP, employment and resident income. However, the rise of water price has a negative impact on regional economic development, mainly reflected in regional GDP, employment and household income. The improvement of water price, water efficiency and water conservancy technology would lead to a decrease in regional water consumption, while only the increase of the water supply would lead to an increase in water consumption. Accordingly, the paper puts forward policy suggestions, such as accelerating the improvement of water conservancy facilities, establishing a reasonable water price mechanism and actively exploring experience in water conservation and emission reduction.
