Climate change is a significant and growing threat to food security—already affecting vulnerable populations in many developing countries, and expected to affect ever more people in more places, unless action is taken beginning today. Current scenarios for business-as-usual farming under climate change project growing food security challenges by 2050. Worst hit will be underdeveloped regions of the world where food insecurity is already a problem and populations are vulnerable to shocks (Rosegrant et al. 2014). Improvements in agricultural technology and management are expected to increase food security, but if we do not address climate change, climate-related losses in crop and livestock productivity will reduce those gains (Lobell and Gourdji 2012). In this challenging environment, countries will need to contend with shifts in which crops they can best produce, significant changes in global prices, and change in countries’ comparative advantages. New analytical tools that allow policy makers and decision makers to integrate data from the global to the local level offer an important opportunity for countries to identify the most effective ways to address climate change. As the 22nd Conference of the Parties (COP22) gets underway and the role of agriculture as a key element in reducing emissions is widely recognized, countries can use these tools to identify locally appropriate policies that will reduce the impact of climate change on food security over the long term.

The consequences of climate change for society are analysed in this landmark assessment from the IPCC. This book assesses the available knowledge on the many issues that society has to face, including the international decision-making framework; applicability to climate change of techniques for assessing costs and benefits; the significant social costs of projected climate change; and the economic assessment of policy instruments to combat climate change, nationally and internationally. Some important conclusions of this Second Assessment Report indicate that 10 to 30% of greenhouse gas emissions in most countries can be reduced at negative or zero cost - 'no regrets' measures. Also, the literature indicates that climate change will cause aggregate net damage, which provides an economic rationale for going beyond 'no regrets' measures. It also indicates that a portfolio of mitigation, adaptation and research measures is a sound strategy for addressing climate change given the remaining uncertainties. This report speaks directly to the issues that are faced by the many countries committed to limit emissions of greenhouse gases by the year 2000, and currently negotiating actions to be taken beyond that date. Will be of great value to the international community of policymakers interested in the consequences of climate change, as well as to economists, social and natural scientists.

Why, when so many people understand the severity of environmental problems, is progress so slow and sustainability such a distant goal? What gets in the way? Perhaps you have immediately thought of several barriers. In Obstacles to Environmental Progress, Peter Schulze identifies 18 practical obstacles that routinely and predictably hinder U.S. progress on existing environmental problems. The obstacles apply to problems small and large and, in most cases, regardless of whether an issue is controversial. Though the book focuses on the U.S., most of the obstacles pertain elsewhere as well. The obstacles fall into three categories: scientific challenges to anticipating and detecting problems; political and economic factors that interfere with responding; and obstacles to effective responses. While all the obstacles are predictable and common, they have not been systematically studied as related phenomena, perhaps because they span a wide range of academic disciplines. In practice, they often arise as surprises that are then addressed in an ad hoc manner. Might they be better understood and thus more readily anticipated and overcome or avoided? The book seeks to hasten environmental progress by forewarning and thus forearming those who are striving or will soon be striving for environmental progress, and by drawing scholarly attention to the obstacles as a set of related phenomena to systematically understand and more quickly overcome. Praise for Obstacles to Environmental Projects ‘I have never come across another book that gives students such an accessible and helpful guide to the broad scope of the challenges facing an environmentally sound and sustainable future.’ – Al Wurth, Lehigh University

Most books on environment law focus on the law first, and then look at how environmental problems are dealt with in relation to the law. Taking a fresh approach, Environmental Law from the Policy Perspective: Understanding How Legal Frameworks Influence Environmental Problem Solving examines environmental problems first, followed by an examination
