Download or read book Africa Water Atlas written by United Nations Environment Programme and published by UNEP/Earthprint. This book was released on 2010 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Africa Water Atlas is a visual account of Africa's endowment and use of water resources, revealed through 224 maps and 104 satellite images as well as some 500 graphics, hundreds of compelling photos plus a brief profile of the water situation in every country. These visual elements vividly illustrate a succinct narrative describing and analysing Africa's water issues and exemplifying them through the judiciious use of case studies. The Atlas tells the paradoxical story of a continent with adequate renewable water resources, but unequal access because the water is either abundant or scarce depending on the season or the place. it explores the opportunities to develop Africa's untapped water resources and human capacities to deliver safe drinking water and sanitation services to achieve the water-related Millennium Development Goals, As well as hydropower and irrigation services that help support livelihoods and boost economic development.

Download or read book Aquatic Ecosystems written by Nicholas V. C. Polunin and published by Cambridge University Press. This book was released on 2008-09-11 with total page 941 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern about future supplies of fresh water to society, to meet the full range of human needs, now comes very high on the priority list of global societal issues. An overarching issue, which this book addresses, is whether global climate change is a dominant driver of change in the structure and function of all natural water-based ecosystems, or whether direct human population growth and accelerated consumption are playing an equal or greater role. This book divides the whole aquatic realm into 21 ecosystems, from those on land (both saline and fresh water) to those of the open and deep oceans. It draws on the understanding of leading ecologists to summarize the state and likely condition by the year 2025 of each of the ecosystems. Written for academic researchers and environmental professionals, the aim is to put the climate change debate into a broader context as a basis for conservation science and planning.
Download or read book Crop Adaptation to Climate Change written by Shyam Singh Yadav and published by John Wiley & Sons. This book was released on 2011-08-02 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major task of our time is to ensure adequate food supplies for the world's current population (now nearing 7 billion) in a sustainable way while protecting the vital functions and biological diversity of the global environment. The task of providing for a growing population is likely to be even more difficult in view of actual and potential changes in climatic conditions due to global warming, and as the population continues to grow. Current projections suggest that the world's temperatures will rise 1.8-4.0 by 2100 and population may reach 8 billion by the year 2025 and some 9 billion by mid-century, after which it may stabilize. This book addresses these critical issues by presenting the science needed not only to understand climate change effects on crops but also to adapt current agricultural systems, particularly in regard to genetics, to the changing conditions. Crop Adaptation to Climate Change covers a spectrum of issues related to both crops and climatic conditions. The first two sections provide a foundation on the factors involved in climate stress, assessing current climate change by region and covering crop physiological responses to these changes. The third and final section contains chapters focused on specific crops and the current research to improve their genetic adaptation to climate change. Written by an international team of authors, Crop Adaptation to Climate Change is a timely look at the potentially serious consequences of climate change for our global food supply, and is an essential resource for academics, researchers and professionals in the fields of crop science, agronomy, plant physiology and molecular biology; crop consultants and breeders; as well as climate and food scientists.
Download or read book Living with Environmental Change written by Kirsten Hastrup and published by Routledge. This book was released on 2014-03-05 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is a lived experience of changes in the environment, often destroying conventional forms of subsistence and production, creating new patterns of movement and connection, and transforming people’s imagined future. This book explores how people across the world think about environmental change and how they act upon the perception of past, present and future opportunities. Drawing on the ethnographic fieldwork of expert authors, it sheds new light on the human experience of and social response to climate change by taking us from the Arctic to the Pacific, from the Southeast Indian Coastal zone to the West-African dry-lands and deserts, as well as to Peruvian mountain communities and cities. Divided into four thematic parts - Water, Landscape, Technology, Time – this book uses rich photographic material to accompany the short texts and reflections in order to bring to life the human ingenuity and social responsibility of people in the face of new uncertainties. In an era of melting glaciers, drying lands, and rising seas, it shows how it is part and parcel of human life to take responsibility for the social community and take creative action on the basis of a localized understanding of the environment. This highly original contribution to the anthropological study of climate change is a must-read for all those wanting to understand better what climate change means on the ground and interested in a sustainable future for the Earth.
Download or read book Smart Technologies for Sustainable Smallholder Agriculture written by David Chikoye and published by Academic Press. This book was released on 2017-04-07 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smart Technologies for Sustainable Smallholder Agriculture: Upscaling in Developing Countries defines integrated climate smart agricultural technologies (ICSAT) as a suite of interconnected techniques and practices that enhance quantity and quality of agricultural products with minimum impact on the environment. These ICSAT are centered on three main pillars, increased production and income, adaptation and resilience to climate change, and minimizing GHG emissions. This book brings together technologies contributing to the three pillars, explains the context in which they can be scaled up, and identifies research and development gaps as areas requiring further investigation. It stresses the urgency in critically analyzing and recommending ICSAT and scaling out the efforts of both developing and disseminating these in an integrated manner. The book discusses, synthesizes, and offers alternative solutions to agriculture production systems and socio-economic development. It brings together biophysical and socioeconomic disciplines in evaluating suitable ICSAT in an effort to help reduce poverty and food insecurity. - Highlights the research gaps and opportunities on climate smart agricultural technologies and institutional arrangements - Provides information on institutional engagements that are inclusive of value chain actors that support partnerships and the development of interactive platforms - Elaborates some of the effects of climate extremes on production and socioeconomic development on small farms whose impact has potentially large impact
