As globalization restructures agriculture and rural communities, the impacts of increasingly industrialized farming make interdisciplinary analyses of the linkages among the social, environmental, and economic aspects of farming ever more vital. This collection analyzes the reasons for the public’s scrutiny of intensive agriculture and the prospects for sustainable farming now that concerns are mounting about food quality, manure runoff, greenhouse gases, extra-label use of antibiotics, pesticide use, and rural conflict. Intensive Agriculture and Sustainability outlines the advantages of Farming Systems Analysis for understanding the implications of modern, intensive agriculture. This book describes some of the major environmental and social problems connected with intensive farming; outlines a framework for analyzing its sustainability; discusses key linkages among the environmental, economic, and social indicators; outlines modelling trade-offs between profitability and environmental sustainability; and then analyzes various farming systems using case studies. The authors conclude that rural conflict and government regulation are likely to continue unless the public joins with farmers to help fund stewardship practices and stabilize farm incomes. This book will appeal to field practitioners, agricultural and environmental policy analysts, geographers, and those scholars and students who are tired of the pervasive production-oriented disciplinary focus that typifies most agricultural research.

Climate and environment of Gaia, mother Earth, are under multiple significant stresses. The increase in world population demands large increases in food production, but this must be reached by use of sustainable methods. Emission of climate gasses needs to be dramatically decreased, overall ecological footprints have to be diminished, and socioeconomy of rural areas has to be boosted. These aims are not easy to combine. However, the bio-economy and green solutions may provide mankind with tools of great value both to mitigate pollution and climate change and to adapt to future changes. It is clear that all forms of agriculture cause changes in balances and fluxes of pre-existing ecosystems, thereby limiting resiliency functions. Intensive agriculture in regions that are influenced by industrial pollution, with strong reduction of landscape structures and vast decoupling of energy and matter cycles, has caused stress and degradation of the production base; massive influence has also been exerted on neighbouring compartments. Average yields are probably close to 50 % of maximum yield many places, due to mismanagement of the crops during the production phase, or due to the inappropriate use of key resources. This relationship often leads to a mis-match between input of resources and process outputs, and creates pollution and unbalance in the landscape. Fertilizer runoff and salt accumulation occurs if water supply is in surplus or deficiency, due to soil compaction after use of large machines, and pollinating insects are suffering in regions with large monocultures and high pesticide inputs. These few examples show some of the dilemmas of using input factors in a way that does not fit with the overall conditions. Hence it will be as important as ever to develop new agricultural systems exploiting seasonal growth cycles through intercropping and the integration of mixed perennial crops to ensure permanent availability of plant fractions to be delivered to end users. The problem of degrading soils threatened by overuse, compaction, pollution and loss of biology can only be tackled by a cross disciplinary research approach addressing the entire spectrum of agricultural, environmental and socioeconomic functions of our agricultural systems. While efforts to demonstrate the benefit of site-specific management are relatively recent and have taken various approaches, they specifically refer to variable-rate applications of single inputs, e.g. seeds, fertilizers, chemicals. It is high time to deploy principles of precision agriculture for integrated crop management through combined variable inputs of irrigation water, fertilizers, composts and crop density to improve degrading land and on the other side produce valuable raw products for biorefineries and biobased industries In order to implement such novel production systems, for food and non-food products, the demonstration of land use changes, for biodiversity, for sufficient food and biomass production is essential, with emphasis on the diversity of species and varieties grown, harvested and converted to valuable products. Therefore this Research Topic combines studies demonstrating improved use of soil amendments, nutrients, as well as improved soil fertility for higher resilience against climate stress and recuperation of abandoned or contaminated soils for cropping and animal husbandry. Mixed cropping for high biomass production to create higher added value through the production and transformation of green biomass into novel products is presented as one of the solutions. Applied research for a sustainable and ecologically compatible land use aimed at sufficient food production is as important as ever. Adequate management plans have to be developed from modeling and implemented to increase soil life at the level of the local farm and the region. Growing biomass plants for biorefinery processes should lower production costs, avoid pollution of surface and groundwater, reduce pesticide residues, reduce a farmer’s overall risk, and increase both short- and long-term farm profitability. Such production systems are established amongst the authors of this Research Topic and will allow to obtain an integrated picture of the role of closed cycling loops for N, P and K, and water in an agricultural ecosystem. The next step will be to support decision-making using sustainability indicators and toolboxes as they have been developed for different agricultural systems. The availability of stable research networks of study sites across Europe will help to develop decision support systems applicable across a variety of domains for integrated food and non-food production in the EU, in regards to socio-economy, sustainability and ecology.

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.

Sustainable intensification (SI) has emerged in recent years as a powerful new conceptualisation of agricultural sustainability and has been widely adopted in policy circles and debates. It is defined as a process or system where yields are increased without adverse environmental impact and without the cultivation of more land. Co-written by Jules Pretty, one of the pioneers of the concept and internationally known and respected authority on sustainable agriculture, this book sets out current thinking and debates around sustainable agriculture and intensification. It recognises that world population is increasing rapidly, so that yields must increase on finite land and other resources to maintain food security. It provides the first widely accessible overview of the concept of SI as an innovative approach to agriculture and as a key element in the transition to a green economy. It presents evidence from around the world to show how various innovations are improving yields, resilience and farm incomes, particularly for ‘resource constrained’ smallholders in developing countries, but also in the developed world. It shows how SI is a fundamental departure from previous models of agricultural intensification. It also highlights the particular role and potential of small-scale farmers and the fundamental importance of social and human capital in designing and spreading effective innovations.

Showing how the method of sustainability assessment plays a key role in choosing the best agricultural productive mode, this book guides the reader through the process of selecting, from among the various approaches for building farming systems, the method of decision-making that will result in the most appropriate outcome, given the context. Case studies hail from polities as diverse as Portugal and Canada, Argentina and Lebanon. The work thus offers a valuable critical survey of the assessment methods that account for sustainability and economics, and which have developed considerably in the last two decades. The heterogeneous approaches covered here make this volume appropriate for consultation in a wide variety of social, political and geographical contexts.

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.

A move towards more flexible, sustainable agricultural practices is increasingly being seen as the way to address or avoid environmental and economic problems associated with existing, predominantly intensive, farming systems. Through case studies taken from around the world, this book examines the implications of adopting more ecologically sound agricultural practices, both at the level of individual farmers and at the level of larger-scale agro-ecosystems such as water catchments. The emphasis of the book is on human and social aspects, rather than on agronomic or economic considerations, focusing on the learning processes necessary for change to be implemented and, in turn, on the facilitation of that learning through participatory approaches and appropriate institutional support and policy structure.
