Agricultural Water Scarcity

This study assesses the geographical distribution of agricultural water scarcity in Bangladesh in order to streamline the adaptation measures. The agricultural water scarcity was assumed to be a system with five subsystems, namely, groundwater depth, surface water availability, rainfall availability, groundwater salinity for irrigation, and surface water salinity for irrigation. The catastrophe-theory-based multi-criteria decision making approach was used for the estimation of agricultural water scarcity index from five subsystem indices. The obtained results showed that agriculture in about 6.3% of the area of the country is experiencing very high-risk water scarcity, 19.1% with high water scarcity, 37.2% with moderate water risk, and the rest is low or no risk of water scarcity for agriculture. Results showed that the western part of Bangladesh was more vulnerable to agricultural water scarcity. The analysis of the results showed that higher agriculture water scarcity in the northwest region resulted from water unavailability, and in the southwest region it was closely related to poor water quality. The severe areas of water scarcity are very similar to those that are usually regarded as water-scarce. The approach presented in this study can be used for rapid but fair assessment of water scarcity with readily available data, which can be further improved by incorporating other factors related to water scarcity.

The Impact

SUMMARYWater scarcity is a major constraint of agricultural production in arid and semi-arid areas. In the face of future water scarcity, one possible way the agricultural sector could be adapted is to change cropping patterns and make adjustments for available water resources for irrigation. The present paper analyses the temporal evolution of cropping pattern from 1960 to 2008 in the Hetao Irrigation District (HID), China. The impact of changing cropping patterns on regional agricultural water productivity is evaluated from the water footprint (WF) perspective. Results show that the area under cash crops (e.g. sunflower and melon) has risen phenomenally over the study period because of increased economic returns pursued by farmers. Most of these cash crops have a smaller WF (high water productivity) than grain crops in HID. With the increase of area sown to cash crops, water productivity in HID increased substantially. Changing the cropping pattern has significant effects on regional crop water productivity: in this way, HID has increased the total crop production without increasing significantly the regional water consumption. The results of this case study indicate that regional agricultural water can be used effectively by properly planning crop areas and patterns under irrigation water limitations. However, there is a need to foster a cropping pattern that is multifunctional and sustainable, which can guarantee food security, enhance natural resource use and provide stable and high returns to farmers.

This study provides a scientific assessment of water scarcity in the Beijing-Tianjin-Hebei (BTH) city region and investigates its restrictive effects on urban economic development by quantifying economic loss caused by water scarcity based on an input–output optimization model. The results show that the water scarcity reflected by shadow prices has significant sectoral and regional heterogeneities. Southern Hebei faces the most severe water scarcity in the BTH city region and the situation is worsening. Water scarcity is shown to have a negative impact on the economy of the BTH city region that amounts to CNY 270.02 billion. Hebei has the largest potential economic loss caused by water scarcity, especially in southern Hebei, the potential GDP (gross domestic product) of which is decreased by 6.2%. This study also points out that the water scarcity in the BTH city region is underestimated in terms of actual water prices, and the scarcity of agricultural water use is mostly underestimated. The results contribute to a deeper understanding of the restrictive impact of water scarcity on regional economic development, and thus provide a scientific reference for policymaking in the BTH city region.

Water Scarce

Beijing, the capital of China, is one of the most water-scarce metropolises in the world. The present water policies are leading to serious water scarcity in agriculture. The proportion of agricultural water to total water has been dropping continuously in Beijing in past years. The influence of water scarcity on grain yield and planting production value has been analyzed in this paper. The problems of ecological environment and rural social problems that arise from water scarcity are also discussed in the paper. Based on the above analysis, the paper gives some suggestions for alleviating the tension, such as developing water-saving agriculture, adjusting planting structure and properly developing sewage irrigation.
