Water scarcity has been an important issue for many countries. The water scarcity is still growing in some region but may be exacerbated by recent climate change. Both international and domestic reports classified Korea into water scarcity country on the basis of Falkenmark indicator. Korea, however, missed the concept of green water in calculating their annual renewable water resources per capita and erroneously defined them as water scarcity country. A new calculation shows that Korea has no water scarcity with 1712 m3 of annual renewable water resource per capita. Wrong information in Korea was badly used for political propagation and private purpose. This may be happening to other countries. Water resources experts need to include the concept of green water in reanalyzing the annual renewable water resources to provide decision-makers with acceptable guideline. Decision should be made with more reliable ground. 相似文献

Water resources in semi-arid regions like the Mediterranean Basin are highly vulnerable because of the high variability of weather systems. Additionally, climate change is altering the timing and pattern of water availability in a region where growing populations are placing extra demands on water supplies. Importantly, how reservoirs and dams have an influence on the amount of water resources available is poorly quantified. Therefore, we examine the impact of reservoirs on water resources together with the impact of climate change in a semi-arid Mediterranean catchment. We simulated the Susurluk basin (23.779-km2) using the Soil and Water Assessment Tool (SWAT) model. We generate results for with (RSV) and without reservoirs (WRSV) scenarios. We run simulations for current and future conditions using dynamically downscaled outputs of the MPI-ESM-MR general circulation model under two greenhouse gas relative concentration pathways (RCPs) in order to reveal the coupled effect of reservoir and climate impacts. Water resources were then converted to their usages – blue water (water in aquifers and rivers), green water storage (water in the soil) and green water flow (water losses by evaporation and transpiration). The results demonstrate that all water resources except green water flow are projected to decrease under all RCPs compared to the reference period, both long-term and at seasonal scales. However, while water scarcity is expected in the future, reservoir storage is shown to be adequate to overcome this problem. Nevertheless, reservoirs reduce the availability of water, particularly in soil moisture stores, which increases the potential for drought by reducing streamflow. Furthermore, reservoirs cause water losses through evaporation from their open surfaces. We conclude that pressures to protect society from economic damage by building reservoirs have a strong impact on the fluxes of watersheds. This is additional to the effect of climate change on water resources. 相似文献

AbstractWater availability is one of the most important factors for economic development in the Middle East. The Water Evaluation And Planning (WEAP) model was used to assess present and future water demand and supply in Syria till 2050. Nonconventional water resources, climate change, development, industrial growth, regional cooperation, and implementation of new water saving techniques/devices were considered important factors to include in the analysis using the WEAP model. Six scenarios were evaluated depending on the actual situation, climate change, best available technology, advanced technology, regional cooperation, and regional conflict. The results display a vital need for new water resources to balance the unmet water demands. Climate change will have a major effect on Syrian water resources; possible regional conflict will also to a major extent affect water balance. However, regional cooperation and using the best available technology can help in minimizing the gap between supply and demand.

The processes of formation and distribution of the resources of fresh groundwater and surface water in the territory of Crimea Peninsula are considered. Water availability in the natural–historic and administrative regions of the republic is characterized. The proportions between different categories of groundwater resources are shown with their role in water supply to Crimea taken into account. The presentday development of groundwater resources is analyzed and the possible increase in water consumption meeting geoecological requirements is substantiated. 相似文献

Water is a critical natural resource upon which all social and economic activities and ecosystem functions depend. With a surprising social and economic development in the past decades, water has become an important constraint for China’s sustainable development, and a matter concerning economic security, ecological security and national security of the country. Understanding the changes of water resources is greatly helpful in analyzing the impacts of climatic change, formulating plans for utilization and protection of water resources, and making water resource decisions. Based on China’s national water resources assessment, the Mann-Kendall’s test, and Morlet wavelet, we analyzed the changing trends and periods of China’s renewable water resources during 1956–2010. The results as following: (1) There is no significant change trend of water resources on the countrywide scale during the period 1956–2010, the total water resources show a slight increasing trend, and the national annual average water resources during the period 1991–2010 increased by 1% relative to that of the period 1961–1990. (2) The changes of water resources in different level-I water resource regions vary significantly. Annual average water resources of the Haihe River and Yellow River regions in the northern China decreased 19% and 17% respectively in the past 20 years. Water resource increased in Southern and Northwestern rivers regions, particularly in the Northwest rivers region, with the increasing amplitude by nearly 10% in the past 20 years. (3) The inter-annual variation of national water resource became larger in the past 20 years, as compared with that of the period 1961–1990. The coefficients of water resource variation increased in Northwestern and Southwestern rivers regions, while the inter-annual variation tended to decrease in the Haihe and the Yellow River regions where significant decline of water resources happened. (4) A 14-year quasi-periodicity of the national water resource variation was detected, overlapping with various periodicities of water resources of different level-I water resource regions. Remarkable uniformity exists between the first or secondary primary periodicity of water resource variation in adjacent level-I water resource regions. 相似文献
