The problems of agriculture in the semi-arid regions; Assessing the possibilities for improving agriculture; Soil conservation; Water conservation; Water harvesting and use; Applications of water conservation.
Have agricultural management efforts begun in the desperation of the Dust Bowl brought us to where we need to be tomorrow? Questions about the environmental footprint of farming make this book required reading. Approximately 62% of the total U.S. land area is used for agriculture, and this land also provides critical ecosystem functions. Authors from each region of the continental United States describe the progress of soil and water conservation to date and visualize how agricultural production practices must change in future years to address the newest challenges.
Chapter 3 gives a review of the various tillage systems as they may be applied for soil and water conservation, based the soil characteristics and on different mechanization levels.

The problems related to the process of industrialisation such as biodiversity depletion, climate change and a worsening of health and living conditions, especially but not only in developing countries, intensify. Therefore, there is an increasing need to search for integrated solutions to make development more sustainable. The United Nations has acknowledged the problem and approved the “2030 Agenda for Sustainable Development”. On 1st January 2016, the 17 Sustainable Development Goals (SDGs) of the Agenda officially came into force. These goals cover the three dimensions of sustainable development: economic growth, social inclusion and environmental protection. The Encyclopedia of the UN Sustainable Development Goals comprehensively addresses the SDGs in an integrated way. It encompasses 17 volumes, each devoted to one of the 17 SDGs. This volume addresses SDG 2, namely "End hunger, achieve food security and improved nutrition and promote sustainable agriculture" and contains the description of a range of related terms, to allow for a better understanding and foster knowledge. Our planet produces enough food to feed everyone. Malnutrition and hunger are the result of inappropriate food production processes, bad governance and injustice. SDG 2 seeks to guarantee quality and nutritious food to ensure healthy life by adopting a holistic approach that involves various actions targeting different actors, technologies, policies and programs. These initiatives have to face challenges coming from extensive environmental degradation, loss of biodiversity and the interrelated effects of climate change. Concretely, the defined targets are: End hunger and ensure access by all people, in particular the poor and people in vulnerable situations, including infants, to safe, nutritious and sufficient food all year round End all forms of malnutrition, including achieving the internationally agreed targets on stunting and wasting in children under 5 years of age, and address the nutritional needs of adolescent girls, pregnant and lactating women and older persons Double the agricultural productivity and incomes of small-scale food producers, in particular women, indigenous peoples, family farmers, pastoralists and fishers, including through secure and equal access to land, other productive resources and inputs, knowledge, financial services, markets and opportunities for value addition and non-farm employment Ensure sustainable food production systems and implement resilient agricultural practices that increase productivity and production, that help maintain ecosystems, that strengthen capacity for adaptation to climate change, extreme weather, drought, flooding and other disasters and that progressively improve land and soil quality Maintain the genetic diversity of seeds, cultivated plants and farmed and domesticated animals and their related wild species, including through soundly managed and diversified seed and plant banks at the national, regional and international levels, and promote access to and fair and equitable sharing of benefits arising from the utilization of genetic resources and associated traditional knowledge, as internationally agreed Increase investment, including through enhanced international cooperation, in rural infrastructure, agricultural research and extension services, technology development and plant and livestock gene banks in order to enhance agricultural productive capacity in developing countries, in particular least developed countries Correct and prevent trade restrictions and distortions in world agricultural markets, including through the parallel elimination of all forms of agricultural export subsidies and all export measures with equivalent effect, in accordance with the mandate of the Doha Development Round Adopt measures to ensure the proper functioning of food commodity markets and their derivatives and facilitate timely access to market information, including on food reserves, in order to help limit extreme food price volatility Editorial Board Datu Buyung Agusdinata, Mohammad Sadegh Allahyari, Usama Awan, Nerise Johnson, Paschal Arsein Mugabe, Vincent Onguso Oeba, Tony Wall/div
The management of water resources is extremely important for survival. Depending on the climate, certain regions require different strategies to maintain sustainable hydrological systems. Hydrology and Best Practices for Managing Water Resources in Arid and Semi-Arid Lands is a crucial scholarly resource that outlines current trends in water management and offers solutions for the future of this growing field. Highlighting pertinent topics such as hydrological processes modelling, satellite hydrology, water pollution, and climate resources, this publication is ideal for environmental engineers, academicians, graduate students, and researchers that are eager to discover more about the issues and processes currently shaping water management technology.
Food insecurity is a fundamental challenge to human welfare and economic growth in Africa. Low agricultural production leads to low incomes, poor nutrition, vulnerability to risk and threat and lack of empowerment. This book offers a comprehensive synthesis of agricultural research and development experiences from sub-Saharan Africa. The text highlights practical lessons from the sub-Saharan Africa region.
This compilation opens by presenting a discussion on the main conditions for the successful start-up and operation of full-scale mainstream partial nitrification-anammox technology, advantages of partial nitrification-anammox technology over other technologies of wastewater treatment, and a description of the interactions among key microbial groups and their identification by using metagenomic approaches. Next, one study elucidates the performance of anammox hybrid reactors under various operating conditions to optimize and assess its efficacy and feasibility for nitrogen removal from wastewater. Four numbers of hybrid reactors conglomerating the dual advantages of attached and suspended growth were designed and investigated. The authors seek to produce a soil erosion susceptibility map with selected parameters including elevation, slope, aspect, slope curvature, stream power index, topographic wetness index, cover management factor, land use/land cover, rainfall erosivity, soil erodibility, lineament density, distance from lineament, and distance from stream and drainage density. The weighted linear combination method is applied using remote sensing and geographical information system techniques in the Shiri river basin of Darjeeling, Himalaya. The following study addresses the financial and economic benefits of tourism, and whether these economic benefits are to the detriment of the natural environment. This is done by conducting an investigation into community fishing practices around Mnemba Island. Semi-structured interviews were held with Mnemba Island Lodge staff, local fishermen and local authorities involved in the fisheries around Mnemba Participatory observations were also used to support the data collected by the semi-structured interviews. The authors present data suggesting that of insolation is of high importance for the structuring of floodplain ecosystems because it has potential to impact floodplain lakes regardless of flooding. It is proposed that future investigations of floodplain aquatic habitats should take into account insolation effects other than those of hydrology. The closing chapter provides a brief review of anchovy characteristics, habitats, use, and eco-friendly treatment of anchovy waste/wastewater for reutilization. Anchovy is an attractive resource for the production of functional compounds such as antimutagenic, antifungal, antioxidant and antibacterial agents.
