Recycle Based Organic Agriculture in a City


Book Description

This book highlights the significance of urban agricultural production, the technologies and methods for supplying organic materials to the farmland, recovering plant nutrients and energy in cities, and systems for sustaining farmlands in order to produce agricultural crops and supply safe food to citizens. Focusing on the effective recycling of biomass waste generated in cities for use in organic farming, it discusses alternatives to traditional composting, such as carbonizing organic waste, which not only produces recyclable materials but also converts organic waste into energy. Recycling discarded organic matter appropriately and reusing it as both material and energy is the basis of new urban organic farming, and represents a major challenge for the next generation of urban agriculture. As such, the book presents advanced research findings to facilitate the implementation of safe, organic agricultural production with only a small environmental load.




Advances in Organic Farming


Book Description

Advances in Organic Farming: Agronomic Soil Management Practices focuses on the integrated interactions between soil-plant-microbe-environment elements in a functioning ecosystem. It explains sustainable nutrient management under organic farming and agriculture, with chapters focusing on the role of nutrient management in sustaining global ecosystems, the remediation of polluted soils, conservation practices, degradation of pollutants, biofertilizers and biopesticides, critical biogeochemical cycles, potential responses for current and impending environmental change, and other critical factors. Organic farming is both challenging and exciting, as its practice of "feeding the soil, not the plant provides opportunity to better understand why some growing methods are preferred over others. In the simplest terms, organic growing is based on maintaining a living soil with a diverse population of micro and macro soil organisms. Organic matter (OM) is maintained in the soil through the addition of compost, animal manure, green manures and the avoidance of excess mechanization. - Presents a comprehensive overview of recent advances and new developments in the field OF research within a relevant theoretical framework - Highlights the scope of the inexpensive and improved management practices - Focuses on the role of nutrient management in sustaining the ecosystems




Waste Composting for Urban and Peri-urban Agriculture


Book Description

Rapid urbanization has created a major challenge with regard to waste management and environmental protection. However, the problem can be ameliorated by turning organic waste into compost for use as an agricultural fertilizer in peri-urban areas. This is especially significant in less developed countries, where food security is also a key issue. This book addresses these subjects and is based on papers presented at a workshop held in Ghana by the International Board for Soil Research and Management (IBSRAM, now part of the International Water Management Institute) and FAO. Special reference is given to Sub-Saharan Africa, with acknowledgement to experiences from other parts of the world. Contributing authors are from several European, as well as African, countries.




Advances in Water Management Under Climate Change


Book Description

Due to increasing population, decreased cultivable land, and mounting scarcity of water, it is essential to optimize the use of available resources. Climate change is occurring across the world but its effect may be local or region-specific, including localized watershed management. In order to minimize these effects, governments and environmental agencies encourage the adoption of "climate-smart" agricultural technologies, which involve implementing plans, programs, and projects to sustain and enhance watersheds. Natural ecosystems, in their altered states, have always been relied upon to support the continuity of agricultural production and ecosystem services, such as flood and erosion control, mediation of water quality, stream flow regulation, microclimate regulation, and biodiversity in its various forms. According to the Food and Agriculture Organization of the United Nations, the adoption of these sustainable water management practices has resulted in savings of water and energy as well as a reduction of carbon emissions, decreased erosion, increased organic matter content and biotic activity in soils, increased crop water availability and thus resilience to drought, improved recharge of aquifers, and reduced impact of the variability in weather due to climate change. Advances in Water Management Under Climate Change examines all of these issues and provides best practices for sustainability. Features: Presents the latest research in hydrology, hydraulics, water resources engineering, and agricultural best practices Examines water management practices to best address and ideally mitigate climate change Explains the nexus of agriculture, micro irrigation, AI applications in water management, and the impact of climate change on water resources Includes practical examples to present practical insights on water management for climate change mitigation.




Toward Sustainable Agricultural Systems in the 21st Century


Book Description

In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental, community, labor, and animal welfare standards in agriculture. Toward Sustainable Agricultural Systems in the 21st Century assesses the scientific evidence for the strengths and weaknesses of different production, marketing, and policy approaches for improving and reducing the costs and unintended consequences of agricultural production. It discusses the principles underlying farming systems and practices that could improve the sustainability. It also explores how those lessons learned could be applied to agriculture in different regional and international settings, with an emphasis on sub-Saharan Africa. By focusing on a systems approach to improving the sustainability of U.S. agriculture, this book can have a profound impact on the development and implementation of sustainable farming systems. Toward Sustainable Agricultural Systems in the 21st Century serves as a valuable resource for policy makers, farmers, experts in food production and agribusiness, and federal regulatory agencies.

The Sustainable City XV


Book Description

Consisting of presented papers from the 15th International Conference on Urban Regeneration and Sustainability, the included works address various aspects of the urban environment and provide solutions leading towards sustainability. Urban areas result in a series of environmental challenges varying from the consumption of natural resources and the subsequent generation of waste and pollution, contributing to the development of social and economic imbalances. As cities continue to grow all over the world, these problems tend to become more acute and require the development of new solutions. The challenge of planning sustainable contemporary cities lies in considering the dynamics of urban systems, exchange of energy and matter, and the function and maintenance of ordered structures directly or indirectly supplied and maintained by natural systems. The task of researchers is to improve the capacity to manage human activities, pursuing welfare and prosperity in the urban environment. Any investigation or planning on a city ought to consider the relationships between the parts and their connections with the living world. The dynamics of its networks (flows of energy matter, people, goods, information and other resources) are fundamental for an understanding of the evolving nature of today’s cities. Large cities represent a fertile ground for architects, engineers, city planners, social and political scientists, and other professionals able to conceive new ideas and time them according to technological advances and human requirements. Coastal areas and coastal cities are an important area covered in this volume as they have some specific features. Their strategic location facilitates transportation and the development of related activities, but this requires the existence of large ports, with the corresponding increase in maritime and road traffic and all its inherent negative effects. This requires the development of well-planned and managed urban environments, not only for reasons of efficiency and economics but also to avoid inflicting environmental degradation that causes the deterioration of natural resources, quality of life and human health. These research papers put a focus on sustainability across the multidisciplinary components of urban planning, the challenges presented by the increasing size of cities, the number of resources required and the complexity of modern society.




African Indigenous Vegetables in Urban Agriculture


Book Description

This book provides a comprehensive synthesis of current knowledge of the potential and challenges associated with the multiple roles, use, management and livelihood contributions of indigenous vegetables in urban agriculture in sub-Saharan Africa. There has been growing research and policy effort around urban agriculture in the region over the last two decades, but never has it been integrated with work on under-researched crops such as indigenous vegetables. These species have multiple advantages, including low input requirements, adaptability to African environments, high nutritional value and marked biodiversity, cultural and local food security significance. Yet they are overlooked in the modern world, where recent emphasis has been directed to growing a limited range of exotic crops, both for internal markets and for export to developed country markets. This book provides evidence that, in spite of this neglect, in many African cities indigenous vegetables are still widely used, cultivated and marketed. It goes on to consider their potential to contribute to income generation and poverty alleviation of the growing numbers of urban dwellers in sub-Saharan Africa, whilst promoting urban greening and sustainability. Based on critical analysis of the debates it presents a multidisciplinary analysis of the realities and future opportunities.
