This book was released on 2024-02-27 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we present analysis on the recent historical trend in agriculture in the Eastern and Southern Africa (ESA) region, along with analysis of recent historical trends in temperature and precipitation. We also present 5 climate models and describe the possible future climates associated with these. We use these climate models with crop models -- for seven crops -- and bioeconomic models to further assess the impact on agricultural productivity throughout the region and how the agricultural sector will transform through 2050. While we evaluate seven crops in detail, we note the key role that maize plays for the region, and we assess -- considering the regional and global impact of climate change -- how the role of maize will change over time and whether the change will be rapid enough to shift regional agriculture into a more vibrant sector. We find that while the relative importance of maize to farmers in the region will decline, out to 2050 maize will remain the dominant crop. Additional policies and investments will need to be implemented if the goal is to hasten the transition to higher value or more nutritious crops.
Book Synopsis The Impacts of Climate Change on Regional Water Resources and Agriculture in Africa by : Kenneth M. Strzepek
Download or read book The Impacts of Climate Change on Regional Water Resources and Agriculture in Africa written by Kenneth M. Strzepek and published by World Bank Publications. This book was released on 2007 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper summarizes the methods and findings of the hydrological assessment component of the project studying likely impacts of climate change on water resources and agriculture in Africa. The first phase of the study used a version of a conceptual rainfall-runoff model called WatBal (Water Balance) applied to gridded data to simulate changes in soil moisture and runoff across the whole continent of Africa rather than to any particular catchment or water resource system. The model inputs were the climate variables of the 1961-90 climatology and physiological parameters (such as soil properties and land use) derived from global datasets for each of the 0.5 degree latitude/longitude cells across the continent. The primary model output comprised a time series (monthly time step) of simulated runoff for all the grid cells for each of the districts in the countries of interest. The second phase of the study extended the hydrology analyses to update the above hydroclimatic series to the year 2000 using updated input data. To ascertain the possible impacts of climate change within the districts being investigated this study used synthetic or GCM-based climate change scenarios as input to the WatBal model. The WatBal model was used to determine the impact of these different scenarios on runoff and actual evaporation and hence flow in the districts under study. The generated hydroclimatic series and scenario analyses were used as inputs into various Ricardian regressions in other analyses measuring likely impacts of climate change on the agricultural economies of Africa.
Book Synopsis Investigating the impact of climate change on agricultural production in eastern and southern African countries by : Belloumi, Mounir
Download or read book Investigating the impact of climate change on agricultural production in eastern and southern African countries written by Belloumi, Mounir and published by Intl Food Policy Res Inst. This book was released on with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change has been a significant issue since the end of the 20th century, and impacts a variety of economic sectors, primarily agriculture. The negative impacts of climate change on agricultural production are important because agriculture is closely linked to food security. Although they contribute the least to global pollution, it is estimated that African countries will be the most affected by climate variability. Our paper analyzes the impact of climate change on agricultural production in 11 Eastern and Southern African countries (ESA) during the period from 1961 to 2011 and estimates a panel data model for agricultural production using climate variables (e.g., annual precipitation and annual mean temperature) and economic factors (e.g., livelihood, fertilizer use, machinery, agricultural land, and labor) as explanatory variables.

Available in PDF, EPUB and Kindle. Book excerpt: 'This is a well researched, thorough and impressive work on climate change and agriculture in Africa. I recommend it to students, researchers and practitioners working on climate change issues' Jabavu Clifford Nkomo, senior programme specialist, IDRC This landmark book encompasses a comprehensive assessment of the potential economic impacts of future climate change, and the value of adaptation measures in Africa for different zones, regions, countries and farm types. Researchers developed and applied multiple analytical procedures to assess quantitatively how climate affects current agricultural systems in Africa, enabling them to predict how these systems may be affected in the future by climate change under various global warming scenarios, and suggesting what role adaptation could play. The study is the first to combine spatially referenced household survey data with climatic data at both national and international levels. This book provides vital knowledge about the impacts of climate change on Africa, serving as a guide to policy intervention strategies and investment in adaptation measures. It makes a major contribution to the analysis of climate change impacts and developing adaptation strategies, especially in the highly vulnerable farming communities in the developing world.

Decisionmakers and researchers will find West African Agriculture and Climate Change a vital tool for shaping policy and studying the various and likely consequences of climate change.
Book Synopsis Managing a Changing Climate in Africa by : Pius Z. Yanda
Download or read book Managing a Changing Climate in Africa written by Pius Z. Yanda and published by African Books Collective. This book was released on 2011 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is sufficient evidence to support the fact that climate change is occurring and that this is set to accelerate. While some scholars argue that climate change is largely due to natural changes, others postulate that anthropogenic factors are the major cause. Climate change associated with increasing levels of carbon dioxide is likely to affect developed and developing countries differentially, with major vulnerabilities occurring in low-latitude regions. This book presents research findings and case studies with the endeavour to inform policies geared towards addressing problems emanating from these changes. Climate variability raises concerns over the future of agriculture, conditions of land and water availability. Therefore, climate change amplifies many economic and social risks, as well as deterioration of the environment. At the same time, non-climatic risk factors such as economic instability, trade liberalization, conflicts and poor governance all inflict upon vulnerable communities. Key discussions in this title rest on: Climate Change in Africa: its impact on rural communities, vulnerability and adaptation to climate change, financial requirements of reducing green house gases, technological transfer and natural resources; Case Studies of Vulnerability to Climate Change and Variability in Eastern and Southern Africa: experiences of impacts and adaptation to extreme events, concrete experiences from farmers and crop production adaptation; and Challenges and Opportunities to Climate Change Adaptation: factors that influence choice of response strategies, challenges and opportunities for ecosystem-based approaches; and challenges and opportunities from the use of bio-fuels as a mitigation measure to climate change.

This book was released on 2021-04-13 with total page 831 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-part handbook focuses on the work that the Agricultural Model Intercomparison and Improvement Project (AgMIP) accomplished using a new method — the AgMIP Regional Integrated Assessment Protocol — in Sub-Saharan Africa (SSA) and South Asia (SA), with funding from the UK Department for International Development. Through this research, AgMIP substantially improves the characterization and understanding of food security in SSA and SA and how its affected by climate variability and change.The chapters in this handbook demonstrate how AgMIP has enhanced the capacity of developing country researchers and stakeholders to work together, exploring and prioritizing adaptation to current and future climate stresses. Part 1 describes regional integrated assessment methods and analyses, while Part 2 presents the outcomes of farming system studies. The entire volume shows how AgMIP has established, as a public good, protocols for Regional Integrated Assessments that improve the capability of developing countries to address climate change challenges.Related Link(s)

Book Synopsis Sensitivity of Cropping Patterns in Africa to Transient Climate Change by : Alexander Lotsch
Download or read book Sensitivity of Cropping Patterns in Africa to Transient Climate Change written by Alexander Lotsch and published by World Bank Publications. This book was released on 2007 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: The detailed analysis of current cropping areas in Africa presented here reveals significant climate sensitivities of cropland density and distribution across a variety of agro-ecosystems. Based on empirical climate-cropland relationships, cropland density responds positively to increases in precipitation in semi-arid and arid zones of the sub-tropics and warmer temperatures in higher elevations. As a result, marginal increases in seasonal precipitation lead to denser cropping areas in arid and semi-arid regions. Warmer temperatures, on the other hand, tend to decrease the probability of cropping in most parts of Africa (the opposite is true for increases in rainfall and decreases in temperatures relative to current conditions). Despite discrepancies and uncertainties in climate model output, the analysis suggests that cropland area in Africa is likely to decrease significantly in response to transient changes in climate. The continent is expected to have lost on average 4.1 percent of its cropland by 2039, and 18.4 percent is likely to have disappeared by the end of the century. In some regions of Africa the losses in cropland area are likely to occur at a much faster rate, with northern and eastern Africa losing up to 15 percent of their current cropland area within the next 30 years or so. Gains in cropland area in western and southern Africa due to projected increases in precipitation during the earlier portions of the century will be offset by losses later on. In conjunction with existing challenges in the agricultural sector in Africa, these findings demand sound policies to manage existing agricultural lands and the productivity of cropping systems.

This book was released on 2011-02-11 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compared to many other regions of the world, Africa is particularly vulnerable to the effects of climate change and variability. Widespread poverty, an extensive disease burden and pockets of political instability across the continent has resulted in a low resilience and limited adaptative capacity of African society to climate related shocks and stresses. To compound this vulnerability, there remains large knowledge gaps on African climate, manifestations of future climate change and variability for the region and the associated problems of climate change impacts. Research on the subject of African climate change requires an interdisciplinary approach linking studies of environmental, political and socio-economic spheres. In this book we use different case studies on climate change and variability in Africa to illustrate different approaches to the study of climate change in Africa from across the spectrum of physical, social and political sciences. In doing so we attempt to highlight a toolbox of methodologies (along with their limitations and advantages) that may be used to further the understanding of the impacts of climate change in Africa and thus help form the basis for strategies to negate the negative implications of climate change on society.
Book Synopsis A Ricardian Analysis of the Impact of Climate Change on African Cropland by : Pradeep Kurukulasuriya
Download or read book A Ricardian Analysis of the Impact of Climate Change on African Cropland written by Pradeep Kurukulasuriya and published by World Bank Publications. This book was released on 2012 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines the impact of climate change on cropland in Africa. It is based on a survey of more than 9,000 farmers in 11 countries: Burkina Faso, Cameroon, Egypt, Ethiopia, Ghana, Kenya, Niger, Senegal, South Africa, Zambia, and Zimbabwe. The study uses a Ricardian cross-sectional approach in which net revenue is regressed on climate, water flow, soil, and economic variables. The results show that net revenues fall as precipitation falls or as temperatures warm across all the surveyed farms. In addition to examining all farms together, the study examined dryland and irrigated farms separately. Dryland farms are especially climate sensitive. Irrigated farms have a positive immediate response to warming because they are located in relatively cool parts of Africa. The study also examined some simple climate scenarios to see how Africa would respond to climate change. These uniform scenarios assume that only one aspect of climate changes and the change is uniform across all of Africa. In addition, the study examined three climate change scenarios from Atmospheric Oceanic General Circulation Models. These scenarios predicted changes in climate in each country over time. Not all countries are equally vulnerable to climate change. First, the climate scenarios predict different temperature and precipitation changes in each country. Second, it is also important whether a country is already hot and dry. Third, the extent to which farms are irrigated is also important.

This book was released on 2015-02-13 with total page 1159 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Top agricultural scientists from around the world have taken up the challenge of sustainable agriculture, with the specific focus on integrating agronomic, climatological, biophysical and socio-economic perspectives and processes. Every chapter (of the Handbook) contributes to addressing the growing food-security challenges facing the world.”Foreword by Jeffrey Sachs, Director of the Earth Institute at Columbia UniversityClimate effects on agriculture are of increasing concern in both the scientific and policy communities because of the growing population and the greater uncertainty in the weather during growing seasons. Changes in production are directly linked to variations in temperature and precipitation during the growing season and often to the offseason changes in weather because of soil water storage to replenish the soil profile. This is not an isolated problem but one of worldwide interest because each country has concerns about their food security.The Agricultural Model Intercomparison and Improvement Project (AgMIP) was developed to evaluate agricultural models and intercompare their ability to predict climate impacts. In sub-Saharan Africa and South Asia, South America and East Asia, AgMIP regional research teams (RRTs) are conducting integrated assessments to improve understanding of agricultural impacts of climate change (including biophysical and economic impacts) at national and regional scales. Other AgMIP initiatives include global gridded modeling, data and information technology (IT) tool development, simulation of crop pests and diseases, site-based crop-climate sensitivity studies, and aggregation and scaling.
Book Synopsis Milestones in Green Transition and Climate Compatible Development in Eastern and Southern Africa by : Mukuna, Truphena E.
Download or read book Milestones in Green Transition and Climate Compatible Development in Eastern and Southern Africa written by Mukuna, Truphena E. and published by OSSREA. This book was released on 2016-07-25 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is widely recognised that climate change poses significant serious threats to sustained economic growth and agricultural development, poverty reduction, food security and political stability globally. Nowhere are these challenges more marked than in Africa where two-thirds of all available land is classified either as desert or dry land, in relation to which the Intergovernmental Panel on Climate Change (IPCC) (2013) has classified the continent as the most vulnerable to climate change variability. This anthology is a product of a call from OSSREA to collate evidence based researches in a book in a bid to assess how far countries in eastern and southern Africa are implementing the UNFCCC, Rio+20, Agenda 21 and other global and Africa-wide decisions concerning the need to address climate change. This will contribute to post-2015 development agenda for sustainable development goals (SDGs), in which climate change and disaster risk reduction will be priority areas of focus. The book will serve as a valuable tool for experts, advisers and policymakers in pursing effective green growth policies and practices and achieving climate compatible development and in doing so inspire readers to choose a more sustainable pathway for humanity. It will also help in looking at climate change as both a challenge and opportunity for development. Further, this book aims at stimulating more research in climate compatible development and climate financing which have put most countries at crossroads.
Book Synopsis Sustainable Intensification to Advance Food Security and Enhance Climate Resilience in Africa by : Rattan Lal
Download or read book Sustainable Intensification to Advance Food Security and Enhance Climate Resilience in Africa written by Rattan Lal and published by Springer. This book was released on 2014-10-10 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 32-chapter volume represents the core of several oral and poster presentations made at the conference. In addition to Introduction and Conclusion sections, the book is thematically divided into 7 sections, namely, 1) Land Use and Farming Systems, 2) Effects of Climate Change on Crop Yield, 3) Soil Nutrient and Water Management for Carbon Sequestration, 4) Rehabilitation of Degraded Lands through Forestry and Agroforestry, 5) Management of Animal Production for Greenhouse Gas Emissions, 6) Smallholder Adaptation to Climate Change, and 7) Economic, Social and Policy Issues. It addresses these themes in the context of sustainable intensification (SI). It implies increasing agronomic production from the existing land while improving/restoring its quality and decreasing the C or environmental footprint. Simply put, SI means producing more from less.
Book Synopsis Adapting to Climate Uncertainty in African Agriculture by : Stephen Whitfield
Download or read book Adapting to Climate Uncertainty in African Agriculture written by Stephen Whitfield and published by Routledge. This book was released on 2015-08-20 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Future climatic and agro-ecological changes in Africa are uncertain and associated with high degrees of spatial and temporal variability and this change is differently simulated within divergent climate-crop models and in controlled crop breeding stations. Furthermore, uncertainty emerges in local contexts, not just in response to climatic systems, but to social, economic, and political systems, and often with implications for the appropriateness and adoption of technologies or the success of alternative cropping systems. This book examines the challenges of adaptation in smallholder farming in Africa, analysing the social, economic, political and climatic uncertainties that impact on agriculture in the region and the range of solutions proposed. Drawing on case studies of genetically modified crops, conservation agriculture, and other 'climate smart' solutions in eastern and southern Africa, the book identifies how uncertainties are framed 'from above' as well experienced 'from below', by farmers themselves. It provides a compelling insight into why ideas about adaptation emerge, from whom, and with what implications. This book offers a unique perspective and will be highly relevant to students of climate change adaptation, food security and poverty alleviation, as well as policy-makers and field practitioners in international development and agronomy.
