This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of climate change on the hydrology and water resources of the Bhumibol Dam, upper Ping River basin, Thailand are assessed by utilizing the Intergovernmental Panel on Climate Change Special Report Emission Scenarios (IPCC SRES)-climate scenarios during the 21st century from the fifth generation atmospheric general circulation model of the European Center for Medium Range Weather Prediction (ECHAM5) and the Community Climate System Model version 3.0 (CCSM3). The hydrologic response of streamflow in the upper Ping River basin to the climate change is performed under A1B, A2 and B1 with total 12 projections. The Watershed Environmental Hydrology-Hydro Climate Model (WEHY-HCM) is used to perform dynamical downscaling from the global atmospheric scale (~200 km) to the regional atmospheric scale over the study basin via the MM5 regional atmospheric model at 9 km grid resolution and hourly time intervals. The watershed module then couples the atmospheric and the land surface hydrology processes with its physically based model further, and simulates the watershed flows. The Global Climate Model (GCM)-historical control runs (1971 to 2000) were downscaled, corrected for their bias, and tested for the models' performance by a goodness of fit of model and observed flow cumulative distribution functions. The projected flows from 2001 to 2015 and observed flows were compared, and showed a projected range covering the observed time series. From the established GCMs' reliability in producing future climate variables, the future hydrologic flows of the study area can be generated and the effects of the climate change can be studied. Based on the ensemble average of 12 realizations, the results show that toward the end of 21st century the future projected flows yield a significant upward trend when tested by the Mann-Kendall trend test at 95% confidence level. The study basin will have a streamflow increase of 17.3% (6.36 billion m3) on average, compared to the average flows from 1988 to 2015 (5.24 billion m3). These flows will supply the Bhumibol Dam, which has a total storage of 13.4 billion m3 and active storage of 9.7 billion m3. Thus, the increase in the ensemble mean accumulated annual flow is still less than the dam storage capacity, which will have space to receive additional water at about 4 to 8 billion m3 of the active and total storage, respectively. However, the flood management, the dam operation policy and its structure must be investigated further in detail for the effect of climate change conditions specifically in terms of the effect of natural variability and the effect of maximum flood discharge, which are beyond this research scope. Water balance simulation results show an extreme drought during the first half of the century, and the water shortage situation will decline thereafter due to more projected inflows after 2070. The possible drought mitigation solution of the Bhumibol Dam is by water transfer from a neighboring watershed. This study found that by transferring water to fill the Bhumibol Dam by at least 25% (1,355 mcm) of mean annual discharge (5,241 mcm) would reduce water deficit dramatically at the end of the 21st century. However, water diversion at 35% (1,897 mcm) of the mean annual discharge yields the highest rate of reducing water deficit, and the water transfer at 50% (2,710 mcm) is the optimal volume to minimize the water deficit. Moreover, the water transfer at 80% (4,336.96) of mean annual discharge may be a better solution when the future water demand estimates at the end of the 21st century are included into water balance computations. This study provides a preliminary solution to alleviate a prolonged drought at the Bhumibol Dam reservoir, which would occur every year during the first half of the century. The possible and effective drought mitigation for the Bhumibol Dam, a water diversion project to increase water supply of the dam, may be possible, and needs to be studied in more detail with the consideration of floods as well in a future study.

Download or read book Participation of Local People in Water Management Evidence from the Mae Sa Watershed Northern Thailand written by Helene Heyd and Andreas Neef and published by Intl Food Policy Res Inst. This book was released on 2013 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1990s, Thailand launched an ambitious program of decentralized governance, conferring greater responsibilities upon sub-district administrations and providing fiscal opportunities for local development planning. This process was reinforced by Thailand's new Constitution of 1997, which explicitly assures individuals, communities and local authorities the right to participate in the management of natural resources. Drawing on a study of water management in the Mae Sa watershed, northern Thailand, this study analyzes to what extent the constitutional right for participation has been put into practice. To this end, a stakeholder analysis was conducted in the watershed, with a focus on the local people's interests and strategies in water management and the transformation of participatory policies through government agencies at the local level. Government line departments were categorized into development- and conservation-oriented agencies. While government officers stressed the importance of stakeholder inclusion and cooperation with the local people, there is a sharp contrast between the official rhetoric and the reality on the ground. The analysis reveals that government officers, particularly in the conservation-oriented agencies, are not disposed to devolve power to lower levels due to the fear of losing their traditional mandate and persistent stereotypes about local communities' incompetence to manage water resources in a sustainable way. On their part, villagers do not perceive a tangible change in the implementation of water policies and retain a widely negative image of government officers. In conclusion, the participation of local people in development activities and in the conservation and management of natural resources seems to be currently at the stage of passive or, at best, consultative participation. In order to deal with the severely increasing water problems in northern Thailand, decision-makers have to recognize the value of participation and promote a change of government officers' attitude towards local people through training programs and incentives. Communities and individuals need to be made aware of their constitutional rights and potentials for cooperating with government agencies and participating in their projects.

This book was released on 2009 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book presents results of a research program which is characterized by: new areas in research methodology of rural development; focusing on empirical problems in natural resources development, especially water resources, and the relation to living standard of rural people; and impact assessment of problem solving strategies as well as of natural (e.g. disaster) strategies on the future livelihood of rural people with combined family-society and socio-economic-ecological simulation models. In the methodological approach, it combines micro level family view with the society's view at rural regional level by integrating farm management and socioeconomic methods with remote sensing and geographical information systems. Special emphasis is not only given to collection and integration of data of different types, e.g. farmers views in interviews and natural science data as facts from satellite images, but also to the mathematical linkage between family decision models and spatial explicit modeling for simulating the future of the combined interests of individual families and the society at regional level. The empirical analyses centers around the socioeconomic development of different ethnic groups having different access to natural resources, to capital for investment into modern farm production systems, to markets as well as variations in ownership rights. The driving forces behind settlements in new areas (often forests) and the consequences on land use, market supply and living standard of people are analyzed and used for evaluating future strategies. The impact of future problem-solving strategies in the farming business and regional water resources development have been simulated and evaluated based on both the individual families' and the society' objectives using family models and explicit spatial modeling. Furthermore, future developments which are not or to a lesser degree based on individual decision-making, such as increasing land scarcity, changing environmental conditions and climatic changes related to water availability have been forecasted and allow showing limited and even disaster developments in the future. This provides potentials of decision-making in research, extension and policy."--Publisher's description.

This book was released on 2015-08-20 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Confronting Climate Uncertainty in Water Resources Planning and Project Design describes an approach to facing two fundamental and unavoidable issues brought about by climate change uncertainty in water resources planning and project design. The first is a risk assessment problem. The second relates to risk management. This book provides background on the risks relevant in water systems planning, the different approaches to scenario definition in water system planning, and an introduction to the decision-scaling methodology upon which the decision tree is based. The decision tree is described as a scientifically defensible, repeatable, direct and clear method for demonstrating the robustness of a project to climate change. While applicable to all water resources projects, it allocates effort to projects in a way that is consistent with their potential sensitivity to climate risk. The process was designed to be hierarchical, with different stages or phases of analysis triggered based on the findings of the previous phase. An application example is provided followed by a descriptions of some of the tools available for decision making under uncertainty and methods available for climate risk management. The tool was designed for the World Bank but can be applicable in other scenarios where similar challenges arise.
