Organic agriculture has grown out of the conscious efforts by inspired people to create the best possible relationship between the earth and men. After almost a century of neglect, organic agriculture is now finding place in the mainstream of development and shows great promise commercially, socially and environmentally. Integrated organic farming is a commonly and broadly used word to explain a more integrated approach to farming as compared to existing monoculture approaches. It refers to agricultural systems that integrate livestock and crop production and may sometimes be known as Integrated Bio systems. It denotes a holistic system of farming which optimizes productivity in a sustainable manner through creation of interdependent agri-eco systems where annual crop plants (e.g. wheat), perennial trees (e.g. horticulture) and animals (including fishes where relevant) are integrated on a given field or property .This concept of organic farming is based on following principles: 1. Nature is the best role model for farming, since it does not use any inputs nor demand unreasonable quantities of water.2. The entire system is based on intimate understanding of nature's ways of replenishment. The system does not believe in mining of the soil of its nutrients and do not degrade it in any way. 3. The soil in this system is considered as a living entity 4. The soil's living population of microbes and other organisms are significant contributors to its fertility on a sustained basis and must be protected and nurtured, at all cost. 5. The total environment of the soil, from soil structure to soil cover is more important and must be preserved. Integrated Organic farming is a method of farming system, which primarily aims at cultivating the land and raising crops in such a way, so as to keep the soil alive and in good health. It is the use of organic wastes (crop, animal and farm wastes, aquatic wastes) and other biological materials, mostly produced insitu- along with beneficial microbes (bio fertilizers) to release nutrients to crops, which connotes the ‘organic’ nature of organic farming. It is also termed as organic agriculture. In the Indian context it is also termed as ‘Javik Krishi’. We have compiled all the relevant information regarding integrated organic farming in this book. This is first book of its kind which contains reliable details related to organic farming, green manuring, biological nitrogen fixation, uses of vermiculture bio-tech, organic fertilizers for flooded rice ecosystem, biological pest management, press mud as plant growth promoters, bio fertilizer for multipurpose tree species, rice- fish integration, response of crops to organic fertilizer and many more. The book is very useful for farmers, agriculture, universities, consultants and research scholars.

Examine the world's leading aquaculture producers! Sustainable Aquaculture: Global Perspectives is a one-of-a-kind primer on the world's leading sources of aquatic production, presenting expert commentary that includes the latest advancements, developments, and research findings. The book examines essential elements of aquaculture (water quality, nutrition, genetics, culture methods) and addresses problems such as over-fishing, coastal and wetland destruction, and habitat and environmental degradation. Sustainable Aquaculture: Global Perspectives addresses policy measures that are essential for the long-term sustainability of the world's fisheries—and the long-term employment of those who rely on the aquaculture industry for their livelihood. As the world's population increases at an alarming rate, the question of how to ensure global food security is one of extreme importance. But the world's total yield is below expectations and the book examines the reasons why: the under-utilization of natural resources, the lack of adoption of modern scientific methods, the lack of standardized, proven pond fertilization protocols; long-term inbreeding and the loss of genetic variability due to genetic drift. Sustainable Aquaculture: Global Perspectives also addresses: freshwater pearl culture breeding programs pond fertilization regimes fish diseases in tropical climates indoor recirculating culture systems water quality management for shrimp farming and much more! With much of its information available in one place for the first time, Sustainable Aquaculture: Global Perspectives is invaluable as a textbook for introductory aquaculture courses and is an essential resource for professionals and researchers.

The production of biomethane, the renewable version of natural gas, from the biological conversion of organic matter at an industrial scale is fast advancing in several areas of the world. A confluence of factors is fueling the rapid expansion: cost-reducing continuous advances in the technology that make biomethane competitive to fossil natural gas, the emerging concerns over global warming and the need for developing renewable energy resources, and the looming peak oil consequences on the international political-economic stability and in particular the national security of the United States and several major energy importing nations. All types of organic wastes generated by our advanced society, as well as dedicated energy cash crops, can be and are employed separately or combined to produce this renewable fuel. Unlike other biofuels derived from limited food crops, biomethane is a universal natural fuel that is produced in a sustainable fashion because organic fertilizer as a coproduct of the conversion process is used to grow optimally the employed energy crops. Biomethane can be most effectively utilized as a replacement of gasoline and diesel in the transportation sector and is the only practical solution to do so in the foreseeable future. A biomethane-based road transportation system in the United States can generate over 1 trillion dollars in economic output and support 10 million direct and indirect green jobs in manufacturing, engineering, construction, farming, and services. Vision and political will are sufficient to mobilize the vast American natural resources, know-how and economy in order to effect full transition from oil dependency to an indigenous biomethane economy within twenty years.

Population: Answering the Needs and Demands The world’s human populationis 6. 6+ billion people and growing(by 80 million in 2005). Most of the growth is in less developed nations. The Population Reference Bureau (2006) estimates that the global population will reach 7. 9 billion people by 2025. It is projected to stabilize at 9. 2+ billion people by 2050. Governmentsstrive to attract industrial, manufacturing, services, and other projects to advance their economiesandthuscopewithexistingsocial andpoliticalproblemsand futurech- lenges heightened by expanding populations. They are encouraged in these efforts by international lending and development organizations such as the World Bank and the International Finance Corporation. These and other multilateral, regional and sub-regional development banks make funds available for economic and social improvement programs in developing countries (Table p. 1). Well-planned projects can stimulate economic growth and create wealth in a society. This wealth can be used to promote the health, education, and general welfare status of its members, and their employment opportunities even as populations expand. There are many theories that de ne and expound on economic development. Malizia and Feser (1999) summarize the theories in terms of their essential - namics, strengths and weaknesses, and how they are applied to achieve growth. All theories agree that economic advancement is based on investing capital in projects that can ourish and yield nancial gain over extended periods of time.

Fertilizer is a vital component of strategies for expanding foodproduction. The rapid growth in population and the widening food deficits inmany tropical countries ofAsia, Africa, and Latin America call attention to those aspects of fertilization that have been neglected but are expected to yield large economic payoffs in the future. Fertilizer sulfur falls into this category. In the past fertilizer sulfur received little attention from researchers and policymakers since sulfur deficiency was not considered a serious problem. It was not a problem because of low crop yields, extensive cropping, and the incidental supply of sulfur through rain, irrigation water, manures, and sulfurcontaining fertilizers. However, the situation has changed in the last three decades. Moder nagriculture based on high crop yields, intensive cropping, improved crop varieties, and greater use of sulfur-free fertilizers and environmental regula tions restricting sulfur emissions are creating large gaps between sulfur sup ply and sulfur requirements. Sulfur deficiencies are widespread and grow ing. Consequently, the full potential of a modern agricultural system in tropical countries is not being realized. This research effort results from the recognition of the seriousness of the sulfur problem and its adverse impact on food production as well as IFDC's dedication to the development and transfer of economically ef ficient fertilizer technology to tropical countries. This study represents a comprehensive analysis ofthe technical and economic linkages between fer tilizer sulfur and food production, and it provides guidelines for future directions in fertilizer sulfur research and public policy.
