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.

<p>Water, energy and food nexus is an integrated framework suggests that the security of one resource is inevitably linked to another’s. Water availability assures healthy food production whereas agriculture is the dominant user of global freshwater. Water stress due to population growth, climate change or malpractices threatens food security. Within the scope of water for food governance, the water efficiency of agricultural irrigation has to be improved to aid sustainable water and agricultural management. The study investigates water availability and withdrawals, evaluates water resources management scenarios in the agricultural sector in the Sakarya River Basin, Turkey’s third-largest river basin. Demand-oriented management scenarios propose a variety of technical measures which include improvements in irrigation technology, shifts in the cropping pattern and water-saving irrigation strategies. The effectiveness of scenarios was evaluated using the Water Evaluation and Planning (WEAP) system developed for the upper sub-basin where significant agricultural activities are held with approximately 1 million ha of total effective arable land. WEAP is an integrated water resources system modeling that operates based on the principle of water balance accounting. A climate data set of precipitation, temperature, relative humidity, and wind speed were applied across each sub-basin, partitioned into land-use classes. A one dimensional, two-bucket model for each land-use class transmits water as surface runoff, interflow, percolation, baseflow and evapotranspiration components. The model was calibrated and validated for observed streamflow, reservoir volume, and irrigation water amount. The mean annual precipitation and evapotranspiration in the upper sub-basin are 387 mm/a and 245 mm/a respectively. Agriculture is the dominant user of both surface water and groundwater resources and accounts for the %88 of total water withdrawals in the upper sub-basin. Impacts of agricultural management on irrigation water supply and flow dynamics of streamflow gauges were evaluated upon each measure. When compared to a historic baseline scenario, efficient management measures can save irrigation water up to %10 by shifting crop patterns from sunflower to safflower, %6 by establishing drip irrigation instead of sprinkler, %4 by applying deficient irrigation on cereal cultivated areas. Furthermore, mean streamflow increases by %8 in June where deficient irrigation strategy is practiced on cereals, by %9 in October where cropping pattern is shifted from sunflower to safflower. After a review of various technical measures related to the efficient management of water resources, the study concluded that sustainable agricultural development is possible by adapting conservative agricultural practices that assure water and food security.</p>

The focus of this empirical study is to investigate the trends of some hydro metrological parameters and Impact Vulnerability Status (IVS) of irrigation water resources on rice and tomato production in the downstream of Tiga station. Investigation was conducted using data on rainfall, temperature, evaporation and reservoir water level for 30 years in Tiga station. The data collected was used to show the trend fluctuations of each parameter for the period of study. The rainfall data was also used to analyze the Normalized Rainfall Index (NRI) in order to know periods of surplus, deficit and optimal water availability as against the required water for rice and tomato production. The rainfall pattern and water level showed increasing trend while temperature and evaporation showed a general decrease in trend. The NRI used to investigate the IVS in Tiga station downstream revealed that rice and tomato were not vulnerable to drought and flooding for 18 years while every other years were vulnerable or slightly vulnerable. However, only year 1993 appears to be very wet and highly susceptible to flooding. Findings from focus group revealed that 80% of the farmers reported floods occurrences during rainy season and deficit of water between January and March of each year. In conclusion, the IVS of farmers to climate change revealed periods of deficit, optimal and excess water availability for rice and tomato production and their vulnerability status. It was recommended that the government should strengthen laws and policies relevant in addressing climate change

Irrigation Water Demand

Rise in temperature is one of the predicted impacts of climate change with significant implications on water resources management. An attempt has been made to calculate the water requirement of crops in different agro-ecological zones of Palakkad district in humid tropical Kerala using the CROPWAT 8.0 model. Sensitivity analysis was done for a simulated rise in temperature from 0.5 to 3.0 °C keeping other parameters the same. The analysis showed that the total crop water requirement of all the major crops, like coconut, paddy and banana, increased with rising temperature thereby increasing the simulated irrigation water demand. The gross water demand inclusive of irrigation, domestic and industries will be 1,496 Mm3. The simulated gross water demand for an increase in temperature of 0.5, 1.0, 2.0 and 3.0 °C will be 1,523, 1,791, 1,822 and 1,853 Mm3, respectively. The maximum utilizable water resource available in the district is only 1,579 Mm3 and better water management, focusing particularly on improving the irrigation efficiency, has to be adopted to cater for the demands of the user sectors under changing climate scenario. A wide spectrum of climate change scenarios is also discussed in the paper along with guidelines for the future management of water resources.

Despite the significant amount of water resources, Russia is characterized by their uneven distribution over the territory. As a result, a number of regions are characterized by low water availability, due to both physiographic factors and the specifics of the settlement and economic development of the country. This article presents the specific water availability evaluation data calculated for all constituent entities of the Russian Federation, taking into account the resources of both river and lake waters. The calculation of water availability due to lake waters is based on new assessment data on lakes water resources, carried out at the Institute of Limnology, Russian Academy of Sciences. On the basis of the obtained values of water availability, the regions of the greatest water deficit are outlined and their lake fund is estimated. At present almost 60% of the population of Russia lives in regions with low and medium water availability, including about 20% in regions where water availability is characterized as “very low” and “catastrophically low”. Most of these regions belong to the zone of insufficient moisture, however, a number of regions of the zone of sufficient moisture also experience excessive pressure on water resources due to high population. Most of the regions with low and medium water availability have significant reserves of water contained in artificial reservoirs, the total volume of which exceeds 100 km3. In addition, a number of regions also have significant reserves of lake water, including fresh water. Lakes located in the zone of insufficient moisture and characterized by low water availability contain a total of ~ 37 km3 of water, including ~ 20 km3 of fresh water. At the zone of sufficient moisture in the lakes of regions with low water availability ~ 2.4 km3 of fresh water is contained.

This study aimed to assess the spatiotemporal sensitivity of the net irrigation water requirement (NIWR) to changes in climate, for sixteen crops widely cultivated in four irrigation projects located in arid and semi-arid regions of Iraq. Using LARS-WG and five GCMs, the minimum and maximum temperature and precipitation were projected for three periods from 2021–2080 with 20-year steps (P1, P2, and P3) under representative concentration pathways (RCPs) 2.6, 4.5, and 8.5. Weather data available for a reference period from 1990–2019 in four representatives’ meteorological stations were used. The climate variables and other required data were inserted into the CROPWAT 8 NIWR tool. Findings revealed that the increase in the NIWR for the considered crops due to climate change falls in the range 0.1–42.4%, 1.8–44.5%, 1.2–25.1%, and 0.7–14.7% for the North Jazeera Irrigation Project (NJIP), Kirkuk Irrigation Project (KRIP), Upper Khalis Irrigation Project (UKIP), and Dalmaj Irri-gation Project (DLIP), respectively. Barley is more susceptible to changes in climate, whereas maize, potato, soybean, and millet are found to withstand changes in climate better than others. The novel outcomes of this study support optimal spatiotemporal allocation of irrigation water requirement and the sustainable management of water resources in a changing climate in arid and semi-arid regions.

Surface water flowing in the river is a resource of useful raw water to meet the needs of society and as irrigation water is managed by Subak in Bali, Indonesia. Bali has experienced water deficit, along with the increasing number of inhabitants and tourism activities. Results of research of the Ministry of Environment (MOE, 2009) stated that Bali has experienced water deficit of 7.5 billion m3/year in 2000 and 2015 deficit is estimated at as much as 27.6 billion m3 of water/year. The purpose of this research was to evaluate the potential of water in the estuary Saba in order to support ecotourism in coastal areas of the province of Bali and formulating water resource management scheme for coastal areas in Buleleng regency. This research uses quantitative methods with the research location is in the Saba river estuary in Buleleng Regency. Data collected consist of primary data and secondary data. Simulation models for water resources management and statistical analysis using software RIBASIM (River Basin Simulation). As a result of this research is the potential of water in the estuary Saba. The result of measurements in the dry season (September 2013) is amounted to 0.156 m3/sec and in the rainy season (January 2014) of 1,023 m3/sec. Potential water in Saba river estuary based on the simulation of RIBASIM is 9.34 million m3/year, can be used as society water domestic for 81 851 inhabitants, for the water industry (hotel) is 1364 rooms, amounted to 2 ha of fish pond water and for irrigation water (agricultural) is 148 ha. Results of water quality research to the smell, color, temperature, turbidity meet quality standards, while taste, and salinity do not meet quality standards. For the chemical aspect, that is pH and detergent meet quality standards while for BOD and COD does not meet the water quality standard Class I. In terms of biology, total coliform does not meet the quality standards of class I. Saba River water potential for ground water of 7.46 million m3 (6%), residual water irrigation (Return Flow) amounted to 54.74 million m3 (41%) and the balance/allocation of water in an area (water District) amounted to 71.54 million m3 (53%). Water resources management in the Saba River estuary for the water potential in the river estuary can be managed by making reservoirs (reservoir), and dam movement and arrangement of the beach.

Abstract This study aims to project the compound impacts of climate change and human activities, including agriculture expansion and hydropower generation, on the future water availability in the Sre Pok River Basin. The five regional climate models (RCMs): ACESS, REMO2009, MPI, NorESM, CNRM were selected for the future climate projection under two scenarios i.e., RCP 4.5 and RCP 8.5. Our results reveal that the future annual rainfall is expected to decrease by 200 mm whereas the average temperature is expected to increase by 0.69°C to 4.16°C under future scenarios. The future water availability of Sre Pok River Basin was projected using soil and water assessment tool (SWAT). Next, the CROPWAT model was used to examine the irrigation water requirement and the HEC-ResSim model to simulate the hydropower generation of Buon Tuar Sarh reservoir. The future simulation indicates the decrease in future water availability, increasing demand for irrigation water and decreases in hydropower generation for the future periods. The irrigated areas are increases from 700 ha to 1500 ha as per the provincial development plan. This study also examines the present and future drought conditions of Sre Pok River via streamflow drought index (SDI). Our results expect to contribute toward supporting the planning and management of water resources for agriculture and to efficiently cope with drought conditions in the studied basin and beyond.

Watershed management with potential water resources greater than or equal to 20% of the potential of water resources in the province requires a device capable of addressing those needs. The Siak river area is a potential source of water resources greater than 20%. Until now, the Siak river area does not yet have an integrated water resource information system; thus information on the potency of water absorption cannot be adequately recorded. Prediction of water availability in watersheds has significance for the management of a watershed. The research aims to develop a hydrological model to strengthen the water availability information to complete the water availability information. The built model is a combination of a conceptual model with wavelet (hybrid model) that is wavelet-ihacres. The wavelet transform method has the advantage of decomposing and reconstructing the data to produce better predictions. The results showed that the combined wavelet-ihacres have a coefficient correlation between observation data and output model of 0.737. The value is classified as a strong correlation.
