For inventory, a survey was conducted as per prestructured proforma. People’s perception was also recorded to verify the inventorization. In Solan Block the total number of water resources recorded in the field were 3218. Out of which 3070 number of water resources are being commercially exploited for use. A total of 412 hand pumps were installed in the area till December 2016. Out of the total water resources in Solan District, 22% ground and 30% surface water resources were in Solan Block. The people’s perception indicated that out of 35 panchayats, seven panchayats had water deficiency. In Solan Block 5.29 sq. km of total area was covered under 18 major irrigation schemes till 2016. A total population of 70,643 in rural area of Solan Block had a water requirement of 13,06,189.07 gallons per day whereas, that of urban population (45,845) was 15,13,801.9 gallons per day. The total water requirement of Solan Block calculated was 28,19,990.97 gallons per day for a population of 1,16,488 (Census 2011). The total water storage capacity in Solan Block on an average was 63,07,388.64 gallons to meet the demand of inhabitants along with water requirement for other purposes. But many times this capacity remained unutilized due to less water availability. Periodic water resource management is thus recommended for sustaining quality water availability.

Total Water Demand

Abstrak Sumberdaya air penting untuk pemenuhan kebutuhan semua makhluk hidup termasuk manusia. DAS Bodri menyediakan suplai air permukaan melalui sungai-sungai yang ada dalam DAS, yang dapat dimanfaatkan oleh penduduk sekitar. Seiring berjalannya waktu, DAS Bodri mengalami perubahan penggunaan lahan yang menyebabkan terjadinya peningkatan kebutuhan air dan terjadi ketidakseimbangan antara kebutuhan dan ketersediaan air permukaan. Tujuan dari penelitian ini, yaitu mengetahui keseimbangan antara kebutuhan air di masa yang akan datang dengan ketersediaan air permukaan di DAS Bodri tahun 2040. Perhitungan keseimbangan antara kebutuhan dan ketersediaan air permukaan dilakukan dengan membandingkan antara kebutuhan air total dan ketersediaan air permukaan. Parameter kebutuhan air total terdiri dari kebutuhan air domestik, fasilitas kesehatan, fasilitas pendidikan, fasilitas peribadatan, perkantoran, industri, pertokoan dan pasar, warung makan, peternakan, irigasi, dan tambak. Kebutuhan air di tahun mendatang diketahui melalui proyeksi secara eksponensial dan tetap dari data jumlah dalam perhitungan parameter. Kebutuhan air untuk aktivitas domestik dan nondomestik diestimasikan mencapai 2,44 miliar m3 pada tahun 2040. Hasil analisis neraca air menunjukkan bahwa status neraca air DAS Bodri tahun 2010-2019 mengalami defisiensi. Hal tersebut menunjukkan bahwa potensi sumberdaya air permukaan masih belum mencukupi untuk pemenuhan kebutuhan air di DAS Bodri hingga tahun 2040. Abstract Water resources play an important role in meeting the needs of all living things, including humans. The Bodri watershed provides surface water supply through rivers on the watershed, which the local residents can use and utilize. Over time, the Bodri watershed underwent landuse change, which led to an increase in water demand, resulting in an imbalance between water demand and surface water availability. Calculation of the balance between demand and surface water availability is done by comparing the total water demand and the surface water availability. This study aims to determine the balance between future water demand and surface water availability in the Bodri watershed in 2040. The parameters used to determine total water demand consist of water needs of the following sectors; domestic, health facilities, educational facilities, religious facilities, offices, industry, shops and markets, food stalls, livestock, irrigation, and ponds. In the coming year, water demand is known through projections exponentially and permanently from the amount of data in the calculation of parameters. Water demand for domestic and non-domestic activities is estimated to reach 2.44 billion m3 in 2040. The water balance analysis results show that the status of the Bodri watershed water balance in 2010-2019 is deficient. The potential for surface water resources is still insufficient to meet the water needs in the Bodri watershed until 2040.

Critical Issues

Crete, located in the South Mediterranean Sea, is characterized by long coastal areas, varied terrain relief and geology, and great spatial and inter-annual variations in precipitation. Under average meteorological conditions, the island is water-sufficient (969 mm precipitation; theoretical water potential 3284 hm3; and total water use 610 hm3). Agriculture is by far the greatest user of water (78% of total water use), followed by domestic use (21%). Despite the high average water availability, water scarcity events commonly occur, particularly in the eastern-south part of the island, driven by local climatic conditions and seasonal or geographical mismatches between water availability and demand. Other critical issues in water management include the over-exploitation of groundwater, accounting for 93% of the water used in agriculture; low water use efficiencies in the farms; limited use of non-conventional water sources (effluent reuse); lack of modern frameworks of control and monitoring; and inadequate cooperation among stakeholders. These deficiencies impact adversely water use efficiency, deteriorate quality of water resources, increase competition for water and water pricing, and impair agriculture and environment. Moreover, the water-limited areas may display low adaptation potential to climate variability and face increased risks for the human-managed and natural ecosystems. The development of appropriate water governance frameworks that promote the development of integrated water management plans and allow concurrently flexibility to account for local differentiations in social-economic favors is urgently needed to achieve efficient water management and to improve the adaptation to the changing climatic conditions. Specific corrective actions may include use of alternative water sources (e.g., treated effluent and brackish water), implementation of efficient water use practices, re-formation of pricing policy, efficient control and monitoring, and investment in research and innovation to support the above actions. It is necessary to strengthen the links across stakeholders (e.g., farmers, enterprises, corporations, institutes, universities, agencies, and public authorities), along with an effective and updated governance framework to address the critical issues in water management, facilitate knowledge transfer, and promote the efficient use of non-conventional water resources.

Surface Water Resources

The calculation of water resources is the fundamental basis for legitimate utilization, effective protection, optimal configuration and optimal dispatch of water resources. Affected by climate change, economic development, and population expansion, the amount of water resources in Fengtai district, one of the central urban areas of Beijing, has undergone major changes. By comparing the results of the second investigation and evaluation of water resources (1956-1998), the paper analyzes the dynamic changes and causes of surface water resources, ground water resources and total water resources in Fengtai district in recent 61a (1956-2016). The results show that the surface water resources of Fengtai district in recent 61a is 37.978 million m3, which is 2.572 million m3 less than the previous investigation; the ground water resources is 92.959 million m3, a decrease of 13.848 million m3; the total water resources is 104.981 million m3, which is 13.830 million m3 less than the previous investigation. The gradual reduction of regional atmospheric precipitation is the main cause of the decline in surface runoff and rainfall infiltration recharge. At the same time, the continuous water-cutting of Yongding River (the biggest inflow river in Fengtai) since 2000 and the anti-seepage project implemented in 2010 further reduced the infiltration of river infiltration .

The consideration of the streamflow seasonality has a high potential to improve the water use. In order to give subsidies to the optimization of water use, it was evaluated the impact of the change of reference annual streamflow by the monthly streamflows in the potential water use throughout the hydrography of Paracatu sub-Basin. It was evaluated the impact on Q7,10 (lowest average streamflow during a 7-day period with an average recurrence of 10 years) and on Q95 (permanent flow present 95% of the time). The use of monthly streamflow to substitute the annual streamflow had a high potential of improvement of water resources use in the sub-Basin studied. The use of monthly Q 7,10 in substitution of annual Q 7,10 increases the potential water use that vary from about 10% in the months of lower water availability to values exceeding 200% in the months with higher availability of surface water resources. The use of monthly Q95 in substitution of the annual Q95 implies in changes oscillating from reduction of 37% in months of higher water restriction to values exceeding 100% in the months of higher availability, so the use of monthly Q95 instead of the annual Q95 enables the more rational and safe use of water resources.

HighlightsA crop suitability index was constructed for the Bundelkhand region of India.The cropping pattern in the region has shifted from cereals to oilseeds and pulses.Nearly 33% more water is needed to meet the total irrigation water requirement of the region.Pearl millet, sesame, and soybean were found to be the most suitable crops for sustainable use of water resources. ABSTRACT.The Bundelkhand region of India is characterized by acute shortages of water due to recurrent failures of the monsoon. This study estimated the water availability, water requirement, and water deficit in the Bundelkhand region using geographic information system (GIS) data. The study identified suitable crops that can be promoted for sustaining the water resources in the region. Total water availability is estimated to be 17.48 billion cubic meters (BCM), of which 91.3% is available for irrigation. The irrigation water deficit is estimated to be 5.31 BCM, which is 1/4 of the crop water requirement. Farmers in the region give high priority to irrigation of water-guzzling cereal crops instead of pulses and oilseed crops, which have lower water requirements. A crop suitability index revealed that pearl millet, sesame, and soybean are the most suitable crops for sustainable use of water resources in the region. An optimum cropping plan to allocate existing land and water resources, coupled with efficient modern technology such as direct-seeded rice, micro-irrigation, etc., can be the best solution to sustain the natural resources and the income of farmers in the study region.

A water rights permit is an important instrument of the Brazilian National Water Resources Policy and aims to ensure the quantitative and qualitative control of watercourses, guaranteeing the maintenance of multiple uses and the right of access to water. Most Brazilian water resource management agencies adopt, in the evaluation of water availability, the maximum water authorized, represented by percentages of the Q7,10 and Q95% reference flows. The State Institute of the Environment, the governing body of the water resources in the state of Rio de Janeiro, calculated water availability based on the maximum water authorized of 50% of Q7,10, and since 2019, 40% of Q95% has been adopted. Considering the difference between the values, we evaluated the magnitude and impact of the current maximum water authorized in granting processes for water use in Rio de Janeiro state, which is inserted almost entirely in subbasin 59. Based on the results, it is recommended to adopt a more conservative criterion represented by 30% of Q95%, estimated at the monthly level.
