Poor performance of the irrigation systems in Southeast Asian countries is a cause for concern considering the increasing water scarcity. Lack of adequate knowledge and systematic ignorance of main system management has been identified as one of the primary factors for the resulting poor performance of these systems. In this study a model has been developed for operating the main canal of these systems by integrating hydraulics of the flow and decision-making technique. The model developed was applied to the main canal of the Phitsanulok Irrigation Project in Northern Thailand. The results of this application approved the concept and envisaged substantial improvement in the operation of the main canal. The model can in general be applied to similar irrigation systems in the developing countries.

As a part of the ongoing power sectors reforms in India, the state of West Bengal is in the process of metering agricultural electricity supply. Based on primary data, this paper presents a first cut assessment of this initiative. Results suggest that the majority of the pump owners benefit from the reforms in two ways: first by having to pay a lower electricity bill for same usage and second through increased profit margins by selling water. This is because in response to changed incentive structure for water selling, water prices rose sharply by 30-50% immediately after metering. In contrast, water buyers have lost out by having to pay higher water charges and face adverse terms of contract. Impact of metering on operation of groundwater markets is less clear; they may expand, contract or remain unchanged. Same holds true for the volume of groundwater extracted, though water use efficiency may go up. At current tariff rates, the electricity utilities are likely to earn less revenue than before. There is also no evidence that quality of electricity supply has improved following metering. These findings are context specific and holds good for West Bengal where high flat tariff had fostered competitive groundwater markets and hence can not be generalised for other Indian states.

Arsenic contamination of rice irrigated with contaminated groundwater contributes to the additional arsenic burden of the population where rice is the staple food. In an arsenic contaminated area, an experimental field-based study done on nine fields elucidated significant positive correlation between arsenic in irrigation water and soil, irrigation water and rice, and also soil and rice both for Boro (groundwater) and Aman (rainwater) rice. Speciation studies showed that for both Boro (cooked) and Aman (raw) rice from contaminated area, 90% of total recovered arsenic was inorganic. In arsenic contaminated, uncontaminated villages, and Kolkata city, daily quantities of arsenic ingested by adult population from cooked rice diet are equivalent to 6.5, 1.8, and 2.3 L, respectively, of drinking water containing WHO guideline value. In contaminated area, daily intake only from cooked Boro rice for 34.6% of the samples exceeded the WHO recommended MTDI value (2 µg In-As day-1 kg-1 body wt), whereas daily intake from Aman rice was below MTDI value as was rice from uncontaminated areas and Kolkata city. Our study indicated that employing traditional rice cooking method as followed in Bengal delta and using water having arsenic<3µgL-1 for cooking, actual exposure to arsenic from rice would be much less.

Enhancing accountability has become an important objective of the governance reforms over the past two decades. Yet, only a few studies have explored the use of social accountability tools in the water sector in particular. This report aims to fill this gap, based on a case study of a donor-funded water, sanitation and hygiene (WASH) program in Nepal. We document and analyze the effects of two types of social accountability tools implemented by the program: public hearings and social audits. We examined how these tools have contributed to increased transparency, participation, voice and accountability, and in turn discuss their potential to reduce corruption. We relied on qualitative methods to collect data in two case study water supply schemes in two districts of Nepal. The study found that the social accountability tools provided a platform for water users to participate and deliberate on issues related to the execution of WASH schemes. However, the scope of accountability narrowly focused on the integrity of the water user committees but did not provide the political resources and means for communities to hold funding and implementing agencies accountable. Furthermore, attention to budget management has not provided space to address environmental and social justice issues related to payment of wages, access to water and decision-making processes in the design of the water scheme and water allocation. Findings from the study also indicate that the concept of deliberation and downward accountability, as envisioned in international development discourses, does not necessarily match with local power relationships and local cultural norms.

The study aims to estimate and predict the aboveground biomass, carbon stock and carbon sequestration potential of different land uses of Northeast India and relate these estimates with the land use changes. Many applications such as carbon stock and sequestration monitoring, forest degradation monitoring, and climate change mitigation, require precise and timely estimation of forest biomass. Although traditional field inventory can reliably estimate forest biomass, remote sensing is emerging as an alternate and fast approach to cover larger area with relative precision for biomass estimation. In this study, a combined approach of field inventory and Landsat OLI derived vegetation indices were used in spatial modelling of aboveground biomass and carbon stock in different land uses. A stepwise multilinear regression algorithm was used to derive the model that used Landsat derived NDVI, SAVI and ARVI as predicators. The predicted AGB ranged from 14.32 to 185.95 Mg ha-1 with an average of 148.78 Mg ha-1. The developed model that used combined vegetation indices showed correlation of R2 = 0.79 with an RMSE of 51.04 Mg ha-1. The present study also applied the empirical model (CO2FIX) to simulate the future scenario of carbon stock and carbon sequestration potential of the different land uses. The carbon stock potential of different land uses were 182.31 Mg ha-1, 158.91 Mg ha-1, 134.98 Mg ha-1, 169.26 Mg ha-1, 133.84, 89.95 Mg ha-1, 128.3 Mg ha-1 and 61.36 Mg ha-1 in Tropical forest, Subtropical forest, Temperate forest, Tropical plantation, Subtropical plantation, Temperate plantation, Shifting fallows and Agricultural land, respectively.
