Book Description :

This volume discusses a broad range of vital issues encompassing the production and consumption of food in the current period of climate change. All of these add up to looming, momentous challenges to food security, especially for people in regions where malnutrition and famine have been the norm during numerous decades. Furthermore, threats to food security do not stop at the borders of more affluent countries – governance of food systems and changes in eating patterns will have worldwide consequences. The book is arranged in four broad sections. Part I, Combating Food Insecurity: A Global Responsibility opens with a chapter describing the urgent necessity for new paradigm and policy set to meet the food security challenges of climate change. Also in this section are chapters on meat and the dimensions of animal welfare, climate change and sustainability; on dietary options for mitigating climate change; and the linkage of forest and food production in the context of the REDD+ approach to valuation of forests. Part II, Managing Linkages Between Climate Change and Food Security offers a South Asian perspective on Gender, Climate Change and Household Food Security; a chapter on food crisis in sub-Saharan Africa; and separate chapters on critical issues of food supply and production in Nigeria, far-Western Nepal and the Sudano-Sahelian zone of Cameroon. Part III examines Food Security and patterns of production and consumption, with chapters focused on Morocco, Thailand, Bahrain, Kenya and elsewhere. The final section discusses successful, innovative practices, with chapters on Food Security in Knowledge-Based Economy; Biosaline Agriculture in the Gulf States; Rice production in a cotton zone of Benin; palm oil in the production of biofuel; and experiments in raised-bed wheat production. The editors argue that technical prescriptions are insufficient to manage the food security challenge. They propose and explain a holistic approach for adapting food systems to global environmental change, which demands the engagement of many disciplines – a new, sustainable food security paradigm.

Book Description :

Global climate change is one of the most important environmental issues facing the world today. The United Nations Framework Convention on Climate Change (FCCC) acknowledges the potential for global climate change to have major effects on the world economy. The work of the Intergovernmental Panel on Cli mate Change (lPCC) is focused on evaluating the scientific data on climate change and analyzing the potential responses to it. One of the primary issues in the global climate change debate is how to adapt to any change that might occur. The process ofidentifying adaptation measures and evaluating their effectiveness is the focus of this book. In dealing with climate change adaptation, the sequence of events in conduct ing these types of analyses can be generalized as follows: • Develop scenarios for the possible range of climate change, • Assess the vulnerability of various sectors of the national economy and infrastructure to climate change, and • Identify and evaluate measures in each sector to adapt to the climate change It is this third step that is the subject of this book. In presenting this material, Chapter 1 gives an overview of the concept of climate change adaptation and the general principles guiding the conduct of analyses in this area. Chapters 2-7 give the results of evaluating climate change adaptation options in the agriculture, water resources, coastal resources, forest and ecosystems, fisheries, and human settlements sectors.

Book Description :

Global change possesses serious challenges for water managers and scientists. In mountain areas, where water supplies for half of the world population originate, climate and hydrologic models are still subject to considerable uncertainty. And yet, critical decisions have to be taken to ensure adequate and safe water supplies to billions of people, millions of farmers and industries, without further deteriorating rivers and water bodies. While global warming is known to cause glaciers’ retreat and reduced snow packs around the world, it is not clear that mountain discharge will be lower. What is widely recognised is that water management must be adapted to accommodate significant regime changes. However, this inevitably involves managing transboundary rivers, adding further complexity to putting principles in practice. This book takes global warming and the importance of mountain areas in world water resources as the starting point. First, it provides detailed reviews of the processes going on in several rivers systems and world regions in Europe (Rhône and Ebro), North America (Canadian Rockies, Western US and Mexico), the Middle East (Jordan), Africa (Tunisia, Kenya and South Africa). These contexts provide case studies and examples that show the difficulties and potential for adaptation to global change. Land-use, economics, numerous modeling approaches are some of the cross-cutting issues covered in the chapters. The volume also includes the views of water practitioners, with two chapters authored by members of the US-Canada International Joint Commission, an industrialist from Western Canada and an environmental leader in Spain. By combining a rich set of contexts and approaches, the volume succeeds in offering a view of the global challenges faced by water agencies, international donors and researchers around the world. A case is made in some chapters to seek adaptive strategies rather than trying to reduce or control resources variability. This requires factoring in land-use, social and economic aspects, especially in developing countries. Another conclusion is that complex problems can and must be posed and negotiated with the help of models, mapping techniques and science-based facts. However complex these may be, there are ways to translate them to easily interpretable and visualisations of alternative scenarios and courses of action. This book provides numerous examples of the potential of such approaches to draft environmental programmes solve transboundary disputes and reduce the economic consequences of droughts and climate instability.

Book Description :

Abstract : Just as human behaviors are the main drivers of most environmental problems, changes in human behaviors can contribute to solutions to environmental problems. In this dissertation issues related to climate change and water resources, two of the greatest environmental challenges of our time, were examined in the Great Lakes region of North America. For both issues, perceptions of impacts and support for potential solutions were described and quantified. Perceptions of climate change and support for mitigation and adaptation strategies were examined at the community level in the Keweenaw Bay Indian Community (KBIC) of northern Michigan. Like many Native American communities, the KBIC is facing potential environmental, economic, and cultural impacts from climate change and its leaders recently passed a formal resolution to address it. Several key themes emerged through 30 semi-structured interviews and 189 respondents of a quantitative mail survey. Tribal members are acutely aware of climate change and its potential wide-ranging impacts, indicating particular concern for culturally-sacred resources such as the region's water. Most agree that Ojibwa values and traditional ecological knowledge need to be emphasized in planning strategies, and support was equally high for potential mitigation and adaptation measures. Findings provide critical insight to KBIC leaders as they develop long-term strategies in support of the recently-passed climate change resolution. The research also adds to the broader literature by introducing indigenous Great Lakes perspectives to discussions of climate change and environmental justice issues facing indigenous cultures worldwide. Issues related to the sustainability of Great Lakes water resources were examined throughout the region following the same qualitative/quantitative research methodology, with the objective of gaining insight on residents' motivations to conserve household water. This work was also designed with the objective of informing policy, as the Great Lakes Compact, signed into law in 2008, requires Great Lakes states to develop and implement water conservation strategies and report on outcomes every five years. Most previous research related to household water conservation occurred in water-stressed contexts, with little known about residents' conservation intentions in the Great Lakes region. Using the Theory of Planned Behavior as a theoretical base, findings from 43 semi-structured interviews and 186 survey respondents revealed that while residents deeply value the region's water resources, few practice household conservation or plan to do so in the future and few perceive others in the region as conserving water. Beliefs about water-related problems focus more on water quality than supply. Attitudes and perceived norms were the most significant predictors of household water conservation intentions, with few reliable trends involving demographic variables. Findings add to the literature and provide valuable insight to water district managers tasked with meeting conservation objectives. Both studies in this dissertation effectively incorporated qualitative and quantitative methodology to help fill knowledge gaps in the scientific literature and provide critical information to those involved in the development and implementation of policy measures, which relies on accurate readings of public sentiment to be effective.

Book Description :

While traditionally framed as a national and international problem, climate change is also an important local issue. For the past fifteen years, while nations have fought over the terms of emissions reductions and the Kyoto Protocol, local governments and communities have been enacting innovative measures that not only prevent emissions of significant quantities of greenhouse gases but also reduce air pollution, save money, and improve the overall quality of life. In the absence of a serious national policy that addresses global warming, these grassroots efforts can and have made a difference. Since 1993, when fourteen pioneering local governments first began to develop programs to reduce greenhouse gas emissions, a national and international movement has formed to fight global climate change through concerted local action. These communities are having a significant effect. A handful of jurisdictions in the United States are preventing over twenty million tons of CO2 from entering the atmosphere annually and have saved over four hundred million dollars in the process. These initiatives include greening the local building codes, creating commercial waste reduction programs, encouraging water conservation, promoting bicycling and fuel-efficient vehicles, upgrading city buildings, advocating for the use of biodiesel for municipal transportation, and designing innovative systems and policies for reduced paper use. Two in-depth case studies-- Fort Collins, Colorado, and Portland, Oregon--demonstrate how two cities have created and implemented climate-friendly and environmentally sound habitats. While most books on global warming focus on national and international implications and policy approaches or serve as guides to help individuals live in an ecologically sound manner, Linstroth and Bell provide a blueprint for local governments to follow. Combining an analysis of existing federal policy with examples of successful local policy, they provide practical examples of measures that can be implemented by communities and local governments across the United States.

Book Description :

Water scarcity is already a critical issue in many regions across the world and in many places water supplies are likely to be further threatened by climate change (Bates et al., 2008). Climate change will affect water availability in these areas both directly and indirectly. The direct effects come about because increased temperature (accompanied by changes in wind, humidity, and solar radiation) may increase evaporative losses from surface water bodies, and also because reduced precipitation lowers the rate of water inflows. In the case of groundwater, these factors will reduce the rate of aquifer recharge (Bates et al., 2008). The indirect effects arise from the biophysical impacts of climate change on vegetation, which are induced from rising temperatures, changing precipitation regimes, and increased atmospheric carbon dioxide levels. As a result of climate change, significant changes are expected in the hydrological cycle. This research is focused in how climate change can affect crop, land, and water allocation over time. The specific issue of this research comes from the following question: Is climate change likely to have a significant impact on the effectiveness of different water conservation policies in the High Plains aquifer region? This study is focused on the American High Plains, one of the most important water-scarce agricultural regions in North America. The study region for this research is a 31-county area overlying the Ogallala aquifer in western Kansas. This region encompasses approximately the western third of Kansas. Across these counties, the estimated remaining usable lifetime for aquifer water ranges from 50 to over 200 years (KGS), representing the range of water available in various parts of the aquifer. A Positive Mathematical Programming (PMP) model (Howitt, 1995) was developed and calibrated to land- and water-use data in the thirty one county area for a base period of 2000-2008. The PMP simulation uses inputs of price conditions and the aquifer level in a given year to predict the acreages planted to each of the major crops and the water use by crop. Decision makers are assumed to maximize profits, given the limited availability of water and arable land. The major crops in the model include wheat, corn, sorghum, soybeans, and alfalfa; the vast majority of historical planted acreage in the case counties is comprised of these five crops. The model was run for each of the case regions after calibrating the PMP model to data from 2000-2008. Calibration ensures that the model predictions fall within a small tolerance of the base period observations. This step avoids the problem of over-specialization (where the model places all of the acreages under one or two of the most profitable crops), and gives realistic acres and water use figures with which to work. The results suggest that the effects of the use of water conservation policies such as water use restriction and permanent conversion to dryland crops have positive effects on the trends of the different variables studied. With the implementation of these two policies, lower levels of total water use and higher levels of saturated thickness result but with a consequence of lower levels of net returns. However, the positive effects are lower in almost all cases if the effects of climate change on the same policies are taken into consideration. The scenarios of higher levels of temperature and lower precipitation levels projected for the region imply a greater demand for water for irrigated crops that results in lower levels of saturated thickness and simultaneously lower levels of net returns.
