The book covers the various aspects of the use of pesticides, their behavior, degradation, and impacts in wetland ricefields, and presents the results of surveys conducted in the Philippines and Thailand. It includes both bibliographic reviews and selected aspects of the experimental results of a research project on pesticide impacts in wetland ricefields. The first phase of the Pesticide Impact' project was developed in the Philippines from 1989 to 1991. It was a multidisciplinary/collaborative approach involving scientists from IRRI, NRI (England), ORSTOM (France), UPLB (Philippines) who studied the effects of pesticides on the environment and on farmers' health, and the economical aspects of their use.

This collection features four peer-reviewed reviews on improving the shelf life of horticultural produce. The first chapter introduces the concept of smart distribution and highlights how optimising the management of produce distribution systems can reduce loss and waste in the horticultural sector and extend shelf life by minimising quality deterioration. The chapter also discusses the use of remote sensing technology to determine food quality. The second chapter reviews a selection of pre- and postharvest strategies used to optimise fruit quality. The chapter considers ways of measuring harvest maturity, as well as the role of temperature controlled environments in extending the shelf life of tree fruit. The third chapter summarises the wealth of recent research on the preservation of fruit quality in mango production, as well as how postharvest operations can be optimised to reduce loss and waste and maximise shelf life, including the use of controlled environments, waxes and edible coatings. The final chapter explores the advantages and disadvantages of cultivating ripening-impaired tomato mutants and genetically engineered genotypes characterized by inhibition of the ripening process. The chapter considers the use of ethylene inhibitors and controlled environments as a means of mitigating devastating yield losses.

This collection features five peer-reviewed reviews on optimising rootstock health. The first chapter explores optimising rootstock health to improve root function, resource-use efficiency, sustainability and agricultural productivity. The chapter also presents a case study on tomato rootstocks as a viable strategy to overcome abiotic stresses in Ghana. The second chapter reviews the important aspects of tree growth and development in apple production which are integral to ensure product quality. The chapter discusses the importance of rootstocks and emphasises the mechanisms and morphological effects of dwarfing on rootstocks. The third chapter considers recent advances in the development and utilisation of fruit tree rootstocks, focussing primarily on apples. The chapter also reviews rootstock tolerance to both abiotic and biotic stresses. The fourth chapter discusses advances in avocado tissue culture for clonal propagation and highlights the potential of this technology for improving the sustainable supply of high-quality avocado plants to support future avocado industry growth. The final chapter addresses the challenges and opportunities in pear breeding, focussing on pear cultivars, pear rootstocks and germplasm resources. The chapter also considers the use of dwarfing as a means of improving particular traits.

In December 1993, ISNAR, in collaboration with International Consortium for Application of Systems Approaches, organized a three-day workshop on systems approaches and -modelling for agricultural development. Sponsored by the Dutch Ministry for Development Cooperation, the workshop was attended by participants from 12 national agricultural research systems (NARS), nine international agricul tural research centers (IARCs), and five advanced research organizations (AROs). Although application of systems approaches in agricultural research and resource management is a rather new field, there is already increasing demand for implemen tation of these approaches. This will require a critical mass of specialists in the NARS and IARCs. Before this critical mass can be obtained, however, the experience that has been gained in this area needs to be evaluated, further possibilities need to be explored, and new objectives and targets need to be set. This book, which contains the papers presented at the workshop, assesses the state of the art of systems approaches in agricultural research, resource management, and rural planning. It also gives an impression of the evolution of this interdisciplinary field and its use in national and international research centers. Another, less tangible, outcome of the workshop was its contribution toward strengthening the network of NARS, IARCs, and AROs. It gave participants and organizers a chance to develop contacts, and provided an opportunity to make the first proposals for collaborative programs. Special thanks are due to Peter Goldsworthy and Luc Boerboom for their crucial role in making the workshop a success in this regard."

The contributions to this collection focus on the intersecting dynamics of gender, generation and class in Southeast Asian rural communities engaging with expanding capitalist relations, whether in the form of large-scale corporate land acquisition or other forms of penetration of commodity economy. Gender, and especially generation, are relatively neglected dimensions in the literature on agrarian and environmental transformations in Southeast Asia. Drawing on key concepts in gender studies, youth studies and agrarian studies, the chapters mark a significant step towards a gendered and 'generationed' analysis of capitalist expansion in rural Southeast Asia, in particular from a political ecology perspective. The collection highlights the importance of bringing gender and generation, in their interaction with class dynamics, more squarely into agrarian and environmental transformation studies. This is key to understanding the implications of capitalist expansion for social relations of power and justice, and the potential of these relations to shape the outcomes for different women and men, younger and older, in rural society. The chapters in this book were originally published in a special issue of The Journal of Peasant Studies.

Rich countries are paying poor countries to fight climate change on their behalf - and one way they are doing it is through carbon sinks. These are reservoirs of organic carbon tied up in plants and in the earth, rather than being in the atmosphere as greenhouse gases. This book looks critically at this mode of climate change mitigation. Can it work? Is it just? Will poorer countries benefit? The book considers the scientific, economic and ethical basis for this type of mitigation. Previous attention has been focused mainly on reducing emissions from deforestation and land degradation (REDD), but this book is one of the first attempts to examine the potential for carbon sinks in agriculture in crop plants and the soil. In assessing this, the author examines exactly how north-south climate mitigation trading works, or does not, and what the pitfalls are. It highlights the complex relationship between agriculture, particularly different forms of farming systems, and the mitigation of climate change. The arguments are backed up by original research with farmers in Brazil to demonstrate the challenges and prospects which these proposals offer in terms of payments for environmental services from agriculture through carbon trading.

Agricultural ecology, or agroecology, deals in general with the structure and function of agroecosystems at different levels of resolution. In this text/reference, the authors describe in terms of agroecology the tropical environments of sub-Saharan Africa, Southeast Asia, and Latin and Central America, focusing on production and management systems unique to each region.

Drawing upon current theoretical debates in social anthropology, development studies and political ecology, and presenting original research from across the Archipelago, this book addresses the changing histories and identities of upland people as they relate in new ways to the natural resource base, to markets and to the state. It is an engaged study, which fills important analytical gaps and addresses real-world concerns, exploring the uplands as components of national and global systems of meaning, power, and production. It offers a significant re-assessment of concepts, processes, histories, relationships and discourses, many of which are not unique to either the uplands or Indonesia, making the book essential and compelling reading for both scholars and practitioners.

Modern Coconut Management is aimed at guiding those who work with small-scale farmers and farmer groups through the complex area of coconut management. It will also be of value to the many processors and others, whose livelihoods depend on coconuts. The emphasis is on the need for training and education of coconut smallholders in how to become good managers, using appropriate techniques and materials. The book combines a wealth of information that exists in this area with new research on diseases and pests and breeding techniques to improve crop performance. The book also deals with coconut based farming systems in which many aspects of the combination of coconuts with other crops and/or animals are discussed. Equally important are processing techniques which are vital to the survival of the coconut industry. There is a section of the book devoted to post-harvest treatment, processing and research where the many new developments in the processing of coconut products are discussed. This book will serve as a valuable reference tool to trainers and agencies working with coconut smallholders, as well as those involved with the processing of coconuts and products.

This specially curated collection features three reviews of current and key research on nutraceuticals in fruit and vegetables. The first chapter provides a brief description of the chemistry of bioactive compounds (BCs) and their presence in temperate fruits, and discusses recent advances in strategies towards improving sustainable crop production for nutraceuticals. It examines polyphenols, carotenoids, vitamin C and production practices that influence bioactive compound synthesis. The second chapter describes the claimed health benefits associated with the antioxidant properties of bioactive compounds found in mangoes, such as vitamin C, phenolics and carotenoids. The chapter also examines specific cell, animal and clinical studies that suggest mango pulp, juice and extract are effective against metabolic diseases and certain forms of cancer. The final chapter considers how developments such as genetic dissection using fruit ripening mutants, new transgenic plants, and molecular breeding have opened a road map for scientists to further unravel the intricacies and regulation of genes governing fruit quality attributes. Improvements in precision in engineering plant genomes have enabled development of novel tomatoes with marketable traits such as higher carotenoid and anthocyanin content, both beneficial for human health.
