Water Scarce

Due to water scarcity, which is worsening due to climate change, rural areas often face the challenge of rural exoduses. Limited water resources restrict local farmers as the opportunities for cultivation in the fields are reduced. This makes rural areas increasingly unattractive. To strengthen rural areas, sustainable water management with a focus on water-reuse is required. Since treated wastewater is a daily resource with calculable quantities available, reused water can contribute to the sustainable strengthening of a region. Therefore, an analysis of water-reuse potentials must be conducted to develop a water-reuse concept and thus increase the application of reused water. For this purpose, a case study of Wuwei as a rural and water-scarce region in China was chosen. By using a geoinformation system, the unfulfilled water-reuse potential can be identified by intersecting the results of the analysis regarding the current water supply and disposal situation with spatial and regional information, such as population data. Hence, the study presents the potential to increase wastewater treatment and water-reuse for, e.g., agricultural irrigation. It is shown that, in the best case, reused water can be increased from 5479 m3 per day to 207,461 m3 per day. Resource efficiency can be further increased by combining water-reuse concepts with land-use strategies adapted to climate change. This will ensure a more sustainable water supply in the future.

Abstract Climate change is causing extreme recession of the mountain glaciers in Central Asia. Also increased evapotranspiration from higher temperatures in arid and semi-arid zones in Uzbekistan. Additionally, climate change has an effect increased exceptional water deficits. In such scenarios Environmental despite for a more sustainable water supply system, available reservoir capacity. Central Asia unlock watershed region, its main rivers are the Amu Darya and the Syr Darya, and its key problems of the region the efficient use of water from these rivers. Supplying water to the Khorezm oasis and Karakalpakstan, Tuyamuyin reservoir is the main water resource. With an increasing population of the region and Aral Sea ecological problems, mounting demand exists for a more sustainable water supply system. Water reservoirs of Central Asian river contribute to the improvement of water resources management in the lower part of the region and thus, play a strategic role in regional water supplication. 70% of Central Asia is arid and semi-arid regions and therefore, water supply for irrigation and population purposes is the main water sector of all Central Asian countries.

The Kafr El Sheikh Water Supply Project is a comprehensive endeavour to provide the physical and institutional resources for an effective and sustainable water supply system for 2 million persons in a developing rural Governorate in the Delta region of Egypt. The paper describes the aims of the Management Component, the institutional development of an integrated water supply and sewerage company and the main activities to-date. These include training, operational improvements, health education and finance development. Further support is required until all engineering and institutional development work has been completed.

Community Based Adaptation

Purpose The study explored the impacts of climate change on water resources, and the community-based adaptation practices adopted to ensure water security in a rural community in Limpopo Province, South Africa. Design/methodology/approach The study was conducted in Limpopo Province, South Africa. The participatory approach was used to allow community members to share their challenges of water scarcity, and the measures they have developed to cope with inconsistent water supply. Findings The study results show that the community obtains water for household consumption from the reticulation system supplied by Mutale River and the community borehole. These resources are negatively impacted by drought, change in the frequency and distribution of rainfall, and increased temperature patterns. The water levels in the river and borehole have declined, resulting in unsustainable water supply. The community-based adaptation practices facilitated by the water committee include observance of restrictions and regulations on the water resources use. Others involve securing water from neighbouring resources. Originality/value This type of community-based action in response to climate change could be used as part of rural water management strategies under climate change.
