Book Description
Quantitative research with respect to the combination of engineering and socialcultural- religious aspects based on the Tri Hita Karana philosophy in Subak irrigation schemes is original in the field of land and water development. A scenario analysis needs a good and careful system approach. Based on a Generic Algorithm the RIBASIM model was applied using the dependable 80% of discharge and shifting the start of land preparation. The results provide evidence that the cropping pattern of the fifth scenario results in an overall optimal agriculture production of the Subak schemes. The recoverable flow considered in the river basin scheme model plays an important role in the optimisation. Nevertheless, if a normal hydro-climate occurs, the other scenarios, especially the first scenario, can be applied as well. When the indigenous knowledge of farmers is compromised with present day knowledge of agricultural and technological developments, capability of these farmers increases, thus reflects the applicability of the Tri Hita Karana philosophy on harmony among people and harmony among people and nature.

Book Description
This book analyzes water policies in South Asia from the perspective of Integrated Water Resources Management (IWRM). It seeks to address the problems of water scarcity, conflict and pollution resulting from the gross mismanagement and over-exploitation of this finite resource. Highlighting the need for IWRM in mitigating abuse and ensuring sustainable use, it discusses issues relating to groundwater management; inter-state water conflicts; peri-urban water use; local traditional water management practices; coordination between water users and uses; and water integration at the grassroots level. With case studies from India, Bangladesh, Pakistan, and Nepal, the innovative, painstaking and transnational researches presented in the volume deal with questions of equity, gender, sustainability, and democratic governance in water policy interventions. It will interest researchers and students of development studies, environmental studies, natural resource management, water governance, and public administration, as also water sector professionals, policymakers, civil society activists and governmental and nongovernmental organizations.

Book Description
Falling or stagnant agricultural growth, increasing dependence on groundwater, climate variability, swift industrialization, and unplanned and unregulated urbanization in South Asia have spawned a variety of challenges for water resources governance, management and use: groundwater overdraft; insufficient, ill-managed and poor-quality freshwater supply vis-à-vis escalating demand; and water pollution. Water policies in each of the South Asian countries thus call for a more holistic understanding for the efficient management, equitable distribution and sustainable use of this scarce resource. Analyzing the economic, demographic and ideological context in which water policies are framed and implemented, this book argues for an integrated framework in formulating and implementing water policies in South Asia. It also highlights some common missing links in the national policies: problems of techno-centric and blueprint approach to water management, growing influence of international donor agencies and inadequate concern for issues such as equity, sustainability, gender sensitivity, accountability, regional diversity in property rights regimes and water management practices, and regional conflicts over water access. The innovative and nuanced knowledge on water resources produced from detailed case studies in India, Bangladesh, Bhutan, Nepal, Pakistan and Sri Lanka will be useful for professionals, academics, policymakers and activists as well as those in development studies, environmental studies, natural resource management and public administration.

Book Description
The Nile River Basin (NRB) is home to more than 200 million people sharing the water resources for agriculture, industry, municipal uses, in-stream navigation, and hydropower generation. A central and existential water management issue for the region is maintaining a sustainable supply of water against increasing population, recurring drought, and climate change. Recent published datasets on future dams reveal an increasingly impounded NRB for hydropower development by upstream and transboundary nations, notably Ethiopia. The most downstream country, Egypt, therefore needs to adapt the operation of High Aswan Dam (HAD), which is key to the country’s water security, to planned dams, such as the Grand Ethiopian Renaissance Dam (GERD). The overarching goal of this dissertation is to derive an adaptive reservoir operating policy under the combined impacts from climate variability, population pressures and planned dams. First, a modeling framework was developed to simulate streamflow and understand reservoir operations in the NRB using satellite earth observations and macroscale hydrologic modeling. The satellite-based framework yielded a reasonable skill in deriving monthly HAD releases in good agreement with measured discharge downstream of the dam. Building upon this satellite-based modeling, the second study evaluated the hydrological potential of the Upper Blue Nile (UBN) basin for meeting the declared hydropower production design from the GERD (5150 MW). The results indicated the hydrology of the UBN limited the hydropower potential of GERD and thus the initial plans to upgrade the GERD capacity (from 5250MW to 6000MW to 6450 MW) have not been beneficial to improving the dam’s hydropower production. The third study presented a blueprint for adapting HAD operation under the impacts of filling/operation of the GERD based on a Water Supply Stress Index (WaSSI). To adapt to a faster GERD filling scenario (e.g., 3-year filling), HAD needs to modify its operation in summer months by elevating the downstream stress level (store more and release less), e.g., WaSSIAG=0.70. Such adaptation can also help HAD recover its normal operating level in four years after GERD is completely filled compared to 7 years with no adaptation scenario. Additionally, maintaining HAD storage at higher levels prior to GERD filling can significantly reduce the HAD recovery period to only 2 years. In the fourth study, a Forecast-based Adaptive Reservoir Operation (FARO) approach is introduced to explore how HAD can improve its operation by using long-term streamflow forecasts. The FARO results showed that the forecast horizon for HAD operation, using perfect forecasts, ranges between 5- and 12-month lead time in low and high demand scenarios, respectively, beyond which the forecast information no longer improves the release decision. . The forecast value to HAD operation is more pronounced in the months following the flooding season (October through December). The work presented in this dissertation provides a tangible way forward for existing dams to adapt their operations to real-world transboundary challenges while inspiring a win-win deal and considering the equitable rights of development in the Nile countries.

Book Description
Integrated Water Resources Management (IWRM) is an approach that promotes the coordinated development and management of water, land and related resources, in order to maximize economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems. Without public interest and participation, successful implementation of IWRM plans for river basin cannot be possible. Further to this, management at the watershed level to assure water supplies to support livelihood (i.e. domestic water, irrigation, industries, etc.) and sustainable groundwater development requires water augmentation through water conservation structures, and pollution control will also play a vital role. In India, because of limited period of rainfall during Monsoon (i.e. three to four months), water conservation and rainwater harvesting have been practiced since ancient days in order to meet water demands throughout the year. These structures are generally constructed and operated through the public participation. Keeping in view of the importance of public partnership, the role of public partnership in context of water-related awareness and practices has been investigated in different parts of the Yamuna River basin. The investigation evaluates the impact of various water conservation devices on livelihood; compares the performance of recently developed water conservation structures with ancient structures; examines spatial variation of water-related problems in the basin; and proposes an institutional setup for effective governance.
