The Ethics of Agricultural Intensification: An Interdisciplinary and International Conversation Paul B. Thompson and John Otieno Ouko* Global agriculture faces a number of challenges as the world approaches the second decade of the third millennium. Predictions unilaterally indicate dramatic increases in world population between 2010 and 2030, and a trend in developing countries toward greater consumption of animal products could multiply the need for prod- tion of basic grains even further. Although global food production in 2000 was estimated to be adequate for the existing population, hunger and malnutrition are persistent problems that have led decision makers to recognize that increasing food production in specific regions may be the most effective way to address food se- rity for impoverished peoples. At the same time, there will need to be policy adju- ments that improve poor people’s access to current food supplies without simultaneously undercutting the ability of local producers to obtain needed cash income. What is more, the uncertain effects of global climate change on agricultural ecosystems complicate planning for this process, while poorly understood processes of globa- zation create additional unknowns from the side of social systems. In short, despite surpluses in many parts of the developed world, finding ways to increase food p- duction on both selected regional and a total global basis remains a priority for many farmers, policy makers and agricultural researchers.

International commitments were made at the World Food Summits in 1996 and 2002 and in the Millennium Development Goals to cut food hunger levels by half by the year 2015. This objective will require the adoption of sustainable agricultural intensification methods that avoid degradation of the earth's natural resources and take into account the needs and livelihoods of rural populations, particularly in developing countries. This publication explores three approaches to an ethical analysis of agricultural intensification strategies, using arguments based on utilitarian, rights-based and virtue-based models.

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.

This book outlines a new paradigm, Sustainable Intensification of Crop Production (SICP), which aims to produce more from the same area of land by increasing efficiency, reducing waste, conserving resources, reducing negative impacts on the environment and enhancing the provision of ecosystem services. The use of ecologically based management strategies can increase the sustainability of agricultural production while reducing off-site consequences. The book also highlights the underlying principles and outlines some of the key management practices and technologies – such as minimum soil disturbance; permanent organic soil covers; species diversification; selection of suitable cultivars, planting time, age and spacing; balanced plant nutrition; agro-ecological pest management; efficient water management; careful management of farm machinery; and integrated crop-livestock production – required to implement SICP. The green revolution (by using high-yielding crop varieties, mono-cropping, fertilization, irrigation, and pesticides) has led to enormous gains in food production and improved world food security. In many countries, however, intensive crop production has had negative impacts on production, ecosystems and the larger environment, putting future productivity at risk. In order to meet the projected demands of a growing population expected to exceed 9 billion by 2050, farmers in the developing world must double food production, a challenge complicated by the effects of climate change and growing competition for land, water and energy. This book will be of immense value to all members of the scientific community involved in teaching, research and extension activities concerning sustainable intensification. The material can be used for teaching post-graduate courses, or as a useful reference guide for policy makers.

This essay explores key features of the intensification of animal production in relation to animal welfare and animal ethics. It looks at some traditional ethical ideas about animal care in order to help explain why the intensification of animal production has become such a prominent social and ethical issue. It suggests that some of the standard claims made by critics of intensive animal production are seriously flawed, and proposes an alternative interpretation to account for some of the key developments in the intensification of animal production. Finally, it explores how this interpretation, if correct, leads us to a different set of actions to address animal welfare concerns in intensive production systems.

Ecological intensification involves using natural resources such as land, water, soil nutrients, and other biotic and abiotic variables in a sustainable way to achieve high performance and efficiency in agricultural yield with minimal damage to the agroecosystems. With increasing food demand there is high pressure on agricultural systems. The concept of ecological intensification presents the mechanisms of ensuring high agricultural productivity by restoration the soil health and landscape ecosystem services. The approach involves the replacement of anthropogenic inputs with eco-friendly and sustainable alternates. Effective ecological intensification requires an understanding of ecosystems services, ecosystem's components, and flow of resources in the agroecosystems. Also, awareness of land use patterns, socio-economic factors, and needs of the farmer community plays a crucial role. It is therefore essential to understand the interaction of ecosystem constituents within the extensive agricultural landscape. The editors critically examined the status of ecological stress in agroecosystems and address the issue of ecological intensification for natural resources management. Drawing upon research and examples from around the world, the book is offering an up-to-date account, and insight into the approaches that can be put in practice for poly-cropping systems and landscape-scale management to increase the stability of agricultural production systems to achieve ‘Ecological resilience’. It further discusses the role of farmer communities and the importance of their awareness about the issues. This book will be of interest to teachers, researchers, climate change scientists, capacity builders, and policymakers. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, forestry, ecology, agronomy, soil science, and environmental sciences. National and international agricultural scientists, policymakers will also find this to be a useful read for green future.
