Performance of a rehabilitated and turned over flow based minor irrigation project with respect to irrigation, agriculture and institutional aspects was assessed. The irrigation system was found performing better. However, inadequacy of irrigation water availability in dry season and spatial inequity of water distribution, even after rehabilitation and irrigation management transfer were the couple of shortcomings which have been observed. In order to augment the water resource of the system, the feasibility of introducing secondary storage reservoir in each outlet command was conceptualized and field tested. Keeping in view the area required for providing secondary reservoirs, the existing water bodies in the command of the study system were surveyed. The utility and functioning of the secondary reservoir was field demonstrated. Utilization of the harvested water in the secondary reservoir for irrigating dry season crop in addition to the irrigation water from the main reservoir have resulted in increasing the yield of sunflower, tomato, brinjal and groundnut by 14.29, 14.95, 16.95 and 20%, respectively. Among the cropping patterns considered, rice–tomato cropping pattern resulted in highest net return (Rs. 29,457 per ha) followed by rice–brinjal cropping pattern (Rs. 22,430 per ha). Highest benefit–cost ratio of 2.09 was obtained for rice–sunflower cropping system. The low input-based scientific fish culture in the secondary storage reservoir has enhanced the fish yield by three fold over traditional practice.

A two-stage rainwater conservation technique was intervened in the farmers field of rainfed shallow low land, in which, part of the rainwater is conserved in rice field up to the weir crest level and the remaining in a refuge for rearing of fish (Catla catla, Labeo rohita, Cirrhinus mrigala and Cyprinus carpio). The conserved rainwater in the refuge is also used for giving supplemental irrigation to rice crop during rainy season and growing a light duty crop in winter season. On-farm experiment was conducted in the farmer’s field for three consecutive years to study the scope and feasibility of this technique in enhancing productivity and cropping intensity. Three different weir heights (15, 20 and 25 cm) were considered as treatments with two replications each. Refuge occupying areas of 5–8 % of the rice field with a depth of 1.75 m were constructed at the downstream side of each plot. As a result of this intervention, the mono-cropped area could be gradually brought under double cropping. The rice yield increased from 1.8 to 5.3 t/ha. Fish yield of as high as 1,693 kg/ha was obtained for a fish rearing period of about 6 months. The net water productivity increased from 3.76 to 7.38 Rs./m3. The highest net return of Rs. 63,572 was recorded in 20 cm weir height plots with a benefit cost ratio of 2.60. The system generated employment opportunity, increased income for farmers and provided nutritional security.

According to the ‘natural flow paradigm’, any departure from the natural flow condition will alter the river ecosystem. River flow regimes have been modified by anthropogenic interventions and climate change is further expected to affect the biotic interactions and the distribution of stream biota by altering streamflow. This study aims to evaluate the hydrologic alteration caused by dam construction and climatic changes in a mesoscale river basin, which is prone to both droughts and monsoonal floods. To analyse the natural flow regime, 15 years of observed streamflow (1950–1965) prior to dam construction is used. Future flow regime is simulated by a calibrated hydrological model Soil and Water Assessment Tool (SWAT), using ensemble of four high resolution (~25 km) Regional Climate Model (RCM) simulations for the near future (2021–2050) based on the SRES A1B scenario. Finally, to quantify the hydrological alterations of different flow characteristics, the Indicators of Hydrological Alteration (IHA) program based on the Range of Variability Approach (RVA) is used. This approach enables the assessment of ecologically sensitive streamflow parameters for the pre- and post-impact periods in the regions where availability of long-term ecological data is a limiting factor. Results indicate that flow variability has been significantly reduced due to dam construction with high flows being absorbed and pre-monsoon low flows being enhanced by the reservoir. Climate change alone may reduce high peak flows while a combination of dam and climate change may significantly reduce variability by affecting both high and low flows, thereby further disrupting the functioning of riverine ecosystems. We find that, in the Kangsabati River basin, influence of dam is greater than that of the climate change, thereby emphasizing the significance of direct human intervention.

The study was conducted in Puri District of Odisha, India along with the introduction of a new technology Alternate Wetting and Drying (AWD) in Rabi 2015. AWD was a very low cost water saving technology and farmers were made aware about it in the selected study area in nine villages, three in each three blocks of Puri district. The selected 144 farmers, 16 from each village who had adopted AWD were interviewed through a pretested interview schedule. 15 variables were taken to assess the socioeconomic profile of the farmers. The variables were quantified in terms of frequency and percentage. Respondents were categorized with respect to variables like social participation, cosmopoliteness, mass media exposure, extension participation, extension contact, progressiveness and scientific orientation on the basis of mean score and Standard Deviation The study revealed that majority (57.63%) of respondents belonged to middle aged category, maximum of 44 respondents (30.5%) having primary level education, majority (68%) of the respondents were marginal farmers, majority (78%) of respondents had high level of social participation, there was homogeneity among extension participation, average annual income, extension contact, mass media exposure, social participation and heterogeneity among all other variables.

Intensified water usage due to rapid industrialization is often dictated by economic policies based on monetary growth rather than sustainable use of environmental resources. In addition, interdependence within economic sectors further interweaves water usage through product transactions, which further makes it difficult to quantify the dynamics of hydro-economic systems at regional, national and global scale. In this study, we investigated the dynamics of domestic virtual water networks (VWN) of 189 countries based on concept of information theory by quantifying network metrics that describes VWN flow capacity, robustness, efficiency and flexibility. These networks represent virtual water interconnected through economic sectors within a specified country built based on environmentally extended multi region input output (EE-MRIO) approach. We further estimated trends associated with network metrics, as well as coupling intensity between metrics with respect to socio-economic indicators, such as, population, Gross Domestic Product (GDP) and Gross National Income (GNI). It was observed that capacity and flexibility of VWNs are strongly and positively correlated indicating that a high capacity VWN can be more flexible. Our results also indicate that, in general a higher percentage of developing countries (i.e. both least developing and developing nations) have exhibited increasing trends in capacity, robustness, efficiency and flexibility of VWN compared to developed nations. It was revealed that the dynamics of VWNs are positively coupled with socio-economic growth for few countries, which indicates the sustainable behavior of VWN with socio-economic growth. Our results argue that the information theory-based metrics by embedding water footprints can holistically capture sustainability aspect of the VWN dynamics.
