This book explores the fundamental determinants of long term changes in agricultural land use and the associated implications for environmental and food security. The book is designed around the idea that each chapter focuses on one driver, or underlying determinant, of land use change at global scale. It starts with key factors which have been influential in the past, such as growth population, incomes and agricultural productivity, thereafter turning to new drivers such as biofuels, climate change and demand for environmental services. Specialized topics include food security outcomes, projections of future agricultural prices, greenhouse gas emissions, the role of globalization and market integration. The book draws heavily on the emerging body of literature on these topics, summarizes key findings and organizes these within a unifying economic framework.
The U.N. predicts the Earth will have more than 9.6 billion people by 2050. With resources already scarce, how will we feed them all? Journalist Lisa Palmer has traveled the world for years, documenting the cutting-edge innovations of people and organizations on the front lines of fighting the food gap.
By 2050, we will have ten billion mouths to feed in a world profoundly altered by environmental change. How will we meet this challenge? In How to Feed the World, a diverse group of experts from Purdue University break down this crucial question by tackling big issues one-by-one. Covering population, water, land, climate change, technology, food systems, trade, food waste and loss, health, social buy-in, communication, and equal access to food, the book reveals a complex web of challenges. Contributors unite from different perspectives and disciplines, ranging from agronomy and hydrology to economics. The resulting collection is an accessible but wide-ranging look at the modern food system.
Environmental engineers support the well-being of people and the planet in areas where the two intersect. Over the decades the field has improved countless lives through innovative systems for delivering water, treating waste, and preventing and remediating pollution in air, water, and soil. These achievements are a testament to the multidisciplinary, pragmatic, systems-oriented approach that characterizes environmental engineering. Environmental Engineering for the 21st Century: Addressing Grand Challenges outlines the crucial role for environmental engineers in this period of dramatic growth and change. The report identifies five pressing challenges of the 21st century that environmental engineers are uniquely poised to help advance: sustainably supply food, water, and energy; curb climate change and adapt to its impacts; design a future without pollution and waste; create efficient, healthy, resilient cities; and foster informed decisions and actions.
Sustainable Intensification (SI) has recently emerged as a key concept for agricultural development, recognising that yields must increase to feed a growing world population, but it must be achieved without damage to the environment, on finite land resources and while preserving social and natural capital. It also recognises that all initiatives must cope with the challenges of climate change to agricultural production, food security and livelihoods. This multidisciplinary book presents state-of-the-art reviews of current SI approaches to promote major food crops, challenges and advances made in technology, and the institutional and policy measures necessary to overcome the constraints faced by smallholder farmers. Adressing the UN's Sustainable Development Goal 2, the various chapters based on evidence and experiences of reputed researchers show how these innovations, if properly nurtured and implemented, can make a difference to food and nutrition security outcomes. Case studies from around the world are included, with a particular emphasis on Asia and Sub-Saharan Africa. The focus is not only on scientific aspects such as climate-smart agriculture, agroecology and improving input use efficiency and management, but also on institutional and policy challenges that must be met to increase the net societal benefits of sustainable agricultural intensification. The book is aimed at advanced students and researchers in sustainable agriculture and policy, development practitioners, policy makers and non-governmental and farmer organisations.
Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.
By 2050, the world population is expected to reach nine billion. And the challenge of feeding this rapidly growing population is being made greater by climate change, which will increasingly wreak havoc on the way we produce our food. At the same time, we have lost touch with the soil—few of us know where our food comes from, let alone how to grow it—and we are at the mercy of multinational corporations who control the crops and give little thought to the damage their methods are inflicting on the planet. Our very future is at risk. In Consumed, Sarah Elton walks fields and farms on three continents, not only investigating the very real threats to our food, but also telling the little-known stories of the people who are working against time to create a new and hopeful future. From the mountains of southern France to the highlands of China, from the crowded streets of Nairobi to the banks of the St. Lawrence River in Quebec, we meet people from all walks of life who are putting together an alternative to the omnipresent industrial food system. In the arid fields of rural India we meet a farmer who has transformed her community by selling organic food directly to her neighbors. We visit a laboratory in Toronto where scientists are breeding a new kind of rice seed that they claim will feed the world. We learn about Italy’s underground food movement; how university grads are returning to the fields in China, Greece, and France; and how in Detroit, plots of vacant land planted with kale and carrots can help us see what’s possible. Food might be the problem, but as Elton shows, it is also the solution. The food system as we know it was assembled in a few decades—and if it can be built that quickly, it can be reassembled and improved in the same amount of time. Elton here lays out the targets we need to meet by the year 2050. The stories she tells give us hope for avoiding a daunting fate and instead help us to believe in a not-too-distant future when we can all sit at the table.
Nourished Planet illustrates what our global food system can be - a collection of the smartest ideas to nourish us all. From urban farmers in Kenya to American doctors to government officials in Egypt, its voices demonstrate how diverse perspectives are coming together to feed the world sustainably.--back cover.
After steadily declining for over a decade, global hunger is on the rise again, while various forms of malnutrition coexist. Climate change is already exacerbating this grim picture, which is why food security and food production will be a major focus of the Intergovernmental Panel on Climate Change’s 6th Assessment Cycle. Thanks to the participation of 250 experts from all around the world, the International Symposium on Food Security and Nutrition in the Age of Climate Change highlighted the importance of food and agricultural systems in the fight against climate change and presented concrete multi-sector solutions to address this global issue. The event placed special emphasis on the regional realities of West Africa and the Canadian North, as well as to the presence of young people and members of Indigenous and Northern communities directly affected by these issues. The summaries of these four days of plenaries, interactive workshops, and special events have been grouped under seven major themes for this publication: 1) Climate change, food security and nutrition: the issues; (2) The agriculture sectors in the context of climate change; (3) Food systems in the face of climate change; (4) Natural resources: challenges and solutions; (5) Food security and nutrition in a changing North; (6) Summary of solutions; (7) Strengthening and adapting regional and international cooperation.
The book is an edited collection of contributions by a distinguished international panel of academics on the main scientific, juridical, and economic aspects involved in the mitigation and adaptation processes imposed by climate change. Explicitly interdisciplinary, the book transversally cuts through different disciplines offering an outline of a phenomenon that is too often left to specific and sectorial insights. The volume is divided into four parts. The first part introduces the main concepts of the book: climate change and sustainability, wellbeing, and mitigation and adaptation. The second part presents the scientific understanding of climate change and explores some of the more pressing issues driving policy development, such as the melting of the glaciers and the impact on coastal areas. The third part discusses significant experiences in the environmental policies both in the European Union and in the United States of America. The last section explains possible approaches to climate change, by exploring the legal and economic aspects of both adversarial and more lenient approaches towards a more sustainable world. It faces four main issues in the economic and juridical context: consumer behaviors, climate litigations, environmental litigations and the alternative forms of dispute resolution on environmental matters, with particular regard to environmental mediation. Offering a new vision of sustainable policies, this volume will be of interest to researchers and students of environmental policy, resource economics, environmental law, sustainable development, and public administration, as well as practitioners and policy makers working in related areas.
