This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changes in water balance variables such as runoff and evapotranspiration (ET) are essential in planning and management of land and water resources. Two major factors affecting these variables are climate and land use change. There is a need to investigate the combined effects of land use and climate change at local scales. Towards that end, the hydrological processes were modeled using the Soil and Water Assessment Tool (SWAT) to investigate the impacts of climate and land use change in Southeast US (Makhtoumi, Li, Ibeanusi, and Chen, 2020). We integrated land use based on the Shared Socioeconomic Pathways (SSPs) with future climate data (CMIP5) to study the combined effects on hydrological response of Upper Choctawhatchee Watershed (UCW.) Future rainfall and air temperature, for two time periods (2040-2069 and 2070-2099), were obtained using Global Climate Models to provide SWAT with the climatic forcing in order to project water balance variables. The simulation was carried out under two radiative forcing pathways of Representative Concentration Pathways (RCP4.5 and RCP6.0.) Our results indicate that increased imperviousness resulted from urbanization has more impact on runoff than that of projected changes in climate. Impacts on water balance variables (runoff, ET, discharge) differed seasonally. Results showed peak surface runoff experienced changes under both emission scenarios in June up to five times increase. Among the water balance variables, ET as the least dominant pathways for water loss, showed the modest changes with the largest decrease during fall and summer. Projections indicated more frequent extreme behavior regarding precipitation, peak surface runoff, water yield (WY) and ET, during midcentury. Discharge was estimated to increase through the year and the highest changes were expected during summer and fall with 186.3% increase in November under RCP6.0. Relying on rainfall for farming along with reduced agricultural land use (11.8%) and increased urban area (47%) and population growth, would likely make the water use efficiency critical. In our second study, we focused on the combined impact of land use and climate change on soil erosion at local scales. Topsoil loss is a widespread environmental concern causing adverse impacts on natural and human systems. Severe weather accompanied with human activities can exacerbate this issue degrading soil health and consequently accelerating global and regional food insecurity and injustice. Erosion impairs soil physical and chemical properties such as infiltration rate, water holding capacity, loss of nutrients including soil carbon and nitrogen. Although, temporal properties of a rainfall event have meaningful implications for soil erosion, spatial heterogeneity of a rainfall contributes substantially and cannot be overlooked. Therefore, in the third chapter we investigated soil loss using SWAT in Northern Mississippi. First, we built a hydrological model and calibrated it for both flow and sediment discharge. Then we developed land use and climate scenarios. The land use scenarios include farming (soybean and corn) and grazing practices. The climate scenarios comprise of four different precipitation time series, S0 which no concentration is forced, while S1, S2, and S3 have 3%, 6%, and 9% concentration in top four rainy days, respectively. We coupled the land use and climate scenarios and evaluated a small watershed (Hickahala Creek Watershed) in response. We classified the subbasins into different classes of soil loss severity and then determined the hotspots for soil loss at subbasin scale. Our result suggests that the resolution of rainfall data is crucial in studying the soil loss. We found that pasture management by itself can manifold soil loss, and if accompanied with extreme rainfalls, soil loss accelerates impacting different subbasins each time. We found that spatial heterogeneity of extreme rainfalls (ERs) can be more substantial than land use in individual extreme rainfalls; however, over a year, soil moisture and type of the management practices (grazing and farming) could contribute more to soil loss. Soil loss can go as high as 350 (ton/ha/yr) under the ERs. Adding only the management practices can increase erosion 3600%. Under S1 parts of watershed yield more than 150 ton/ha/yr (extremely severe). Under S2 and S3 more soil loss hotspots emerge yielding approximately 200 ton/ha/yr. We found that in the hotspots, up to 10% increase in CI can increase annual soil loss up to 75%. Single ER can generate up to 35% of annual soil loss. Under one ER event hotspot subbasins can lose up to 160 ton/ha/day (subbasin 15). The results reveal that adding grazing and farming (S0) under one ER event can increase soil loss by 95%. 32% and 80% increase in rainfall amount in one ER event can increase soil loss by 94% and 285% respectively. Our results suggested the importance of site-specific managements to mitigate soil loss and all the consequences. It is essential to consider the varying sensitivity of subbasins for the sustainability of agricultural landscapes.

Download or read book Climate Change Adaptation Measures in Vietnam written by Philipp Schmidt-Thomé and published by Springer. This book was released on 2014-11-04 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the iterative steps that were successfully undertaken to develop adaptation measures to climate change in two Vietnamese provinces. The methodology used to develop the scientific basis and the societal agreement of the need to adapt to climate change is applicable also to other regions in Vietnam, Asia and worldwide. The uncertainties of climate change models make it difficult to justify investments to finance protection from uncertain impacts. Setting out with the projected climate change impacts in Vietnam, which is one of the most vulnerable countries to climate change, the book describes a methodological approach to assess and evaluate local vulnerabilities of natural resources to climate change and socio-economic impacts, engaging local stakeholders in the development of locally acceptable and economically feasible adaptation measures. The methodological approach to understand the vulnerabilities and to develop climate change adaptation measures was scenario workshops that supported the communication between scientists and stakeholders. The development of climate change adaptation strategies is nearly state-of-the-art in many countries, but often there is still a large step towards implementing climate change adaptation measures on the local level. The challenge in the development of adaptation measures lies in their acceptability by local stakeholders and decision makers. Climate change adaptation measures also usually demand investments. To understand potential future risks the communication methodology was to first get a good understanding of the natural resources (mainly surface and groundwater) and their potential vulnerabilities (current and future). This was followed by developing a common understanding of current risk patterns, as well as underlying vulnerabilities and hazards. Socio-economic developments have an equally strong, and in the short term mostly even stronger, impact on the living environment and natural resources as long-term climate change impacts. The scenario workshops developed a holistic approach on current and potential future risk patterns, with a special focus on surface and groundwater quantities and qualities, natural hazards and sea level rise. Land-use planning was identified as playing a decisive role in minimizing current and future risks. Finally, first adaptation measures for two Vietnamese provinces were developed and shall be implemented over the next years. The methodology that led to these adaptation measures shall be applied in other Vietnamese provinces.

This book was released on 2013-03-29 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to fill a gap in climate-change literature by providing a comprehensive regional study and identifying the overall adaptation challenges in a real-life context. The way in which possible climate impacts interact with a range of other challenges in agriculture, forestry, disaster planning, health care, general economic development, and common livelihoods are presented, and it is argued that greater realism and broader vision are needed in order to address the climate challenge. For instance, unsuitable land- use changes in both coastal and highland regions may increase the vulnerability of rural people, many of whom are already living on the fringes. The author(s) also state(s) that, depending on context, it may be pertinent to address short-term and unsustainable resource use, irregularities in local land management, ineffective governance and social inequality, which are all likely to aggravate the impact of external climate and weather. Not least, it is imperative to integrate general environmental management with any climate-change adaptation effort.

This book was released on 2012-12-23 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the early 2000s, the Environmental Protection Agency's (EPA's) Office of Research and Development, Global Change Research Program, supported three watershed assessments to evaluate different approaches and tools for understanding and managing climate and land-use change impacts on watershed ecological resources. Watershed assessments were conducted for (1) several small rivers in southern Maryland, (2) Arizona's San Pedro River, and (3) California's Sacramento River. In this report, we comparatively analyze the three case-study approaches in order to develop recommendations that may be useful as guidance to others conducting similar assessments. Key insights gained from these studies include: 1. Prioritize locations for studies to maximize decision support. 2. Target selection of stakeholders, establish credibility of underlying methods and models, and incorporate incentives for mutually beneficial results. 3. Provide essential climate science capabilities and tools to project teams. 4. Develop model linkages at the onset, carry out assessment activities at multiple scales, and require explicit uncertainty analysis of results. The watershed assessment case studies described in this report yield richness of detail in terms of methods and results, as well as inform more generally on best practices for conducting future watershed assessments. However these were pioneering studies addressing difficult and complex problems. Future assessments will continue to refine the understanding of how to maximize decision support, including providing necessary keystone capabilities and tools to effectively estimate climate change vulnerabilities, developing and supporting successful stakeholder processes, and characterizing uncertainty and scaling or transferring results to increase their relevance.

Download or read book The impact of government policies on land use in Northern Vietnam An institutional approach for understanding farmer decisions written by Clement, Floriane, Amezaga, Jaime M., Orange, Didier, Toan, Tran Duc and published by IWMI. This book was released on 2007 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report identifies the driving forces for reforestation in three villages of Northern Vietnam. Using an institutional analysis focused on the rules governing upland access and use, the authors assess the relative impact of state policies (reforestation programs and forestland allocation) on land use change. Findings show that the latter are indirectly responsible for reforestation, but not because of the incentives they provided. Instead, they disrupted the local rules governing annual crop cultivation and grazing activities leading to the end of annual cropping. Tree plantation was chosen by farmers as a last resort option. Lessons learned highlight the importance of local level studies and collective rules for land management.

Book excerpt: ABSTRACT IMPACTS OF LAND COVER AND CLIMATE CHANGE ON WATER RESOURCES IN SUASCO RIVER WATERSHED September 2015 AMMARA TALIB, BS., PUNJAB UNIVERSITY LAHORE MS., UNIVERSITY OF MASSACHUSETTS AMHERST Directed by: Professor Tim Randhir Hydrological balance and biogeochemical processes in watershed are significantly influenced by changes in land use land cover (LULC) and climate change. Those changes can influence interception, evapotranspiration (ET), infiltration, soil moisture, water balance and biogeochemical cycling of carbon, nitrogen and other elements at regional to global scales. The impacts of these hydrological disturbances are generally reflected in form of increasing runoff rate and volume, more intense and frequent floods, decreasing groundwater recharge and base flow, elevated levels of sediments and increase in concentration of nutrients in both streams and shallow groundwater. Water quality of Sudbury, Assabet and Concord (SuAsCo) watershed in Massachusetts is also compromised because of influx of runoff, sediments and nutrients. There is a crucial need to evaluate the synergistic effects of LULC change and climate change on the water quality and water quantity in a watershed system. A watershed simulation model is used to simulate hydrologic processes and water quality changes in sediment loads, total nitrogen (TN), and total phosphorus (TP). The model is calibrated and validated with field-measured data. Climatic scenarios are represented by downscaled regional projections from Global Climate Model (GCM) models and regional built out scenarios of LULC are used to assess the impacts of projected LULC and climate change on water quality and water quantity. Simultaneous changes in LULC and climate significantly affect the water resources in the SuAsCo River watershed. Change in climate increased ET (4.7 %) because of high temperature, but independent change in land cover reduced ET (6.5%) because of less available vegetation. Combined change in land cover and climate reduced ET (2.1%) overall, which indicates that land cover change has significant impact on ET. Change in climate increased total run off (6%) and this increase is more significant as compared to 2.7 % increase in total runoff caused by land cover change. Change in land cover increased surface runoff more significantly (69.2%) than 7.9 % increase caused by climate change. Combined change in land cover and climate further increased the average storm peak volume (12.8 percent) because of high precipitation and impervious area in future. There is a potential for reducing runoff, sediments and nutrients loads by using conservation policies and adaptation strategies. This research provides valuable information about the dynamics of watershed system, as well as the complex processes that impair water resources.
