Sustainable Rice Straw Management


Book Description

This open access book on straw management aims to provide a wide array of options for rice straw management that are potentially more sustainable, environmental, and profitable compared to current practice. The book is authored by expert researchers, engineers and innovators working on a range of straw management options with case studies from Vietnam, the Philippines and Cambodia. The book is written for engineers and researchers in order to provide them information on current good practice and the gaps and constraints that require further research and innovation. The book is also aimed at extension workers and farmers to help them decide on the best alternative straw management options in their area by presenting both the technological options as well as the value chains and business models required to make them work. The book will also be useful for policy makers, required by public opinion to reduce greenhouse gas emissions and air pollution, looking for research-based evidence to guide the policies they develop and implement.

Hay and Straw Conservation


Book Description

Discusses hay, hay crops and crop residues in a wide range of situations. This publication deals with the haymaking process, cultivation of hay crops and management of natural hay fields as well as the harvest and conservation of crop residues as animal feed. A series of case studies from Asia, Africa and Latin America illustrate how hay and crop residues can be integrated into production systems.




The Role of Legumes in the Farming Systems of the Mediterranean Areas


Book Description

Legumes are an important source of protein for humans and animals. They provide nutritionally rich crop residues for animal feed, and playa key role in maintaining the productivity of soils particularly through biological nitro gen fixation. They are, therefore, of immense value in rainfed farming systems. The International Center for Agricultural Research in the Dry Areas (ICARDA) has a responsibility for research on food, pasture, and forage legumes. The Center also has the broad objective of improving livestock production in rainfed farming systems. Although food legumes have be~n known and grown by farmers in the WANA region for a long time, their productivity has remained low and variable. Forage legumes, on the other hand, are not so well known by farmers of the region, and their role in the farming systems is not so well understood. Thus, we need to develop the concept of using forage legumes as crops and to fit them into cropping systems. In its efforts to increase the productivity of food legumes and develop the legume-based crop/livestock systems, ICARDA has established a network of scientists in the different National Agricultural Research Systems in the region. To further strengthen this network, ICARDA convened a workshop on 'The Role of Legumes in the Farming Systems of Mediterranean Areas' in Tunis, Tunisia, 20-24 June 1988. This workshop was co-sponsored by UNDP, who also contributed funds for this publication.













Cereal Straw as a Resource for Sustainable Biomaterials and Biofuels


Book Description

Materials from renewable resources are receiving increased attention, as leading industries and manufacturers attempt to replace declining petrochemical-based feedstocks with products derived from natural biomass, such as cereal straws. Cereal straws are expected to play an important role in the shift toward a sustainable economy, and a basic knowledge of the composition and structure of cereal straw is the key to using it wisely. Cereal Straw as a Resource for Sustainable Biomaterials and Biofuels: Chemistry, Extractives, Lignins, Hemicelluloses and Cellulose provides an introduction to straw chemistry. Topics discussed include the structure, ultrastructure, and chemical composition of straw; the structure and isolation of extractives from the straw; the three main components of straw: cellulose, hemicelluloses, and lignins; and chemical modifications of straw for industrial applications. This book will be helpful to scientists interested in the areas of natural resource management, environmental chemistry, plant chemistry, material science, polysaccharide chemistry, and lignin chemistry. It will also be of interest to academic and industrial scientists/researchers interested in novel applications of agricultural residues for industrial and/or recycling technologies. - Provides the basics of straw composition and the structure of its cell walls - Details the procedures required to fractionate straw components to produce chemical derivatives from straw cellulose, hemicelluloses, and lignins - Elucidates new techniques for the production of biodegradable materials for the energy sector, chemical industry, and pulp and paper business
