Water and Sustainable Agriculture
Irrigated agriculture, a vital component of general agriculture, supplies fruits, vegetables, and cereals consumed by humans and grains fed to animals. Consequently, agriculture is the largest user of fresh water globally, and irrigation practices in many parts of the world are biologically, economically, and socially unsustainable. Water management should balance the need for agricultural water and the need for a sustainable environment. Water-use efficiency is the prime challenge in worldwide farming practices where problems of water shortages are widespread. Currently, agriculture is undergoing significant changes in innovative irrigation, fertilizer technology, and agronomic expertise. These elements constitute a vital platform for sustainable agricultural success and for preventing environmental damage. This review presents several processes linked to environmental irrigation, balancing environmental protection with improved agricultural production.
Soil Health Restoration and Management
Meeting the food requirements of an ever-increasing population is a pressing challenge for every country around the globe. Soil degradation has a negative impact on food security by reducing the cultivated land areas, while at the same time the world population is predicted to increase to 9.2 billion in 2050. Soil degradation adversely affects soil function and productivity and degraded soils now amount to 6 billion ha worldwide. The major factors are salinization, erosion, depletion of nutrients due to exhaustive agricultural practices and contamination with toxic metal ions and agrochemicals, which reduces the activity of soil microbe. In addition, poor soil management also decreases ferti...
Alternative Farming Systems, Biotechnology, Drought Stress and Ecological Fertilisation
Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for our children. This discipline addresses current issues such as climate change, increasing food and fuel prices, starvation, obesity, water pollution, soil erosion, fertility loss, pest control and biodiversity depletion. Novel solutions are proposed based on integrated knowledge from agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, philosophy and social sciences. As actual society issues are now intertwined, sustainable agriculture will bring solutions to build a safer world. This book series analyzes current agricultural issues, and proposes alternative solutions, consequently helping all scientists, decision-makers, professors, farmers and politicians wishing to build safe agriculture, energy and food systems for future generations.
Sustainable Agriculture
Sustainability rests on the principle that we must meet the needs of the present without compromising the ability of future generations to meet their own needs. Starving people in poor nations, obesity in rich nations, increasing food prices, on-going climate changes, increasing fuel and transportation costs, flaws of the global market, worldwide pesticide pollution, pest adaptation and resistance, loss of soil fertility and organic carbon, soil erosion, decreasing biodiversity, desertification, and so on. Despite unprecedented advances in sciences allowing to visit planets and disclose subatomic particles, serious terrestrial issues about food show clearly that conventional agriculture is n...
Renewable Energy and Sustainable Development
Contribution of renewable energy to human life is essential for sustainable life on Earth. The renewable energy industry is growing rapidly to fulfil the energy demand of the continuously developing world and has become the focal centre of many researchers across the globe. This development should meet the needs of the present without compromising the ability of future generations to meet their own needs. Sustainable development ties together concerns for the carrying capacity of natural systems with the social challenges faced by humanity. This book is intended to highlight various aspects for applications of renewable energy and sustainability. This work is a collaborative attempt to elaborate useful technical information from many countries across the globe about the competent and effective use of renewable energy systems. This book presents theoretical and experimental analysis, case studies and models in renewable energy systems issues related to Solar Energy, Wind Energy, Bio Energy, Tidal Energy, Geothermal Energy, Fuel Cells, and Energy Storage Systems. This book also contains different considerations in order to develop products contributing to the sustainability of life.

Agroforestry Research Developments
Today, agroforestry ranks high among the significant land-management initiatives that have undertaken the world over the past few decades. Indeed, it is now recognized as an important approach to ensuring food security and rebuilding resilient rural environments. Recent studies have shown that more than one billion hectares of agricultural land have more than 10% tree cover. Of this, 160 million hectares have more than 50% tree cover. Agricultural ecosystems can be further improved through agroforestry to ensure environmental restoration, greater farm productivity, and realization of ecological services, including climate change mitigation and adaptation for improved rural livelihood. Now, a...
