This book examines the history and mechanisms of climatic change in the southern hemisphere, with emphasis on southern Africa. The crucial question, one which affects the lives of millions, is what determines whether there will be rain or drought. Professor Tyson examines this problem first in the context of geologic history. He then discusses present-day circulation and the manner in which the atmosphere modulates wet and dry spells. He proposes a circulation model to account for paleoclimatic changes over the subcontinent during the last 25 millenia. The material presented here represents research accumulated over a period of 17 years. Nothing similar exists for any country in the southern hemisphere.

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.

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.

The term climate change is used to denote any significant but extended change in the measures of climate. The changes could be due to natural variability or as a result of human activities, such as the burning of fossil fuels to produce energy, deforestation, industrial processes, and some agricultural practices. Such activities release large amounts of carbon dioxide and other greenhouse gases into the atmosphere that hang like a blanket around the earth, thus trapping energy in the atmosphere and causing it to warm up. This results increasingly in climate variability, which is characterised by extreme seasonal, annual, temporal and non-spatial variability in temperature, vagaries of precipitation (rainfall patterns and amounts) and/or wind patterns occurring over a prolonged period of time. The last decade (2001 - 2010) has been the warmest on record; with the average temperatures reaching 0.46∞C, above the 1961 - 1990 mean, and 0.21∞C warmer than the 1991 - 2000 period. It has been proved that the African continent is warming up faster, all year-round, than the global avera≥ a trend that is likely to continue. By the year 2100, it is predicted that temperature changes will fall into ranges of about 1.4∞C to nearly 5.8∞C increase in mean surface temperature compared to 1990, and the mean sea level will rise between 10cm to 90 cm (AMCEN 2011). The interior of semiarid margins of the Sahara and central southern Africa will be the most affected by such warming (AMCEN 2011). To tackle the phenomenon of climate change effectively, human societies have put in place a combination of mitigation and adaptation mechanisms and strategies. Whereas mitigation aims at avoiding or lessening the impacts of the unmanageable, the goal of adaptation is to manage the unavoidable. That men and women are affected differently by climate change suggests that they also differ in terms of the adaptation mechanisms they employ. Despite the existence of gender-based differences in the effects of climate change and in adaptation and coping strategies, studies on the gender differential impacts of climate change and variability on women in general and pastoralist women in particular in sub-Saharan Africa are limited. This volume offers insights and knowledge that pastoralist women developed on climate change adaptation through their experiences in their households and communities and thereby tries to narrow this gap.

Climate change is expected to have serious environmental, economic, and social impacts on South Africa. In particular, rural farmers, whose livelihoods depend on the use of natural resources, are likely to bear the brunt of adverse impacts. The extent to which these impacts are felt depends in large part on the extent of adaptation in response to climate change. This research uses a "bottom-up" approach, which seeks to gain insights from the farmers themselves based on a farm household survey. Farm-level data were collected from 794 households in the Limpopo River Basin of South Africa for the farming season 2004-2005. The study examines how farmer perceptions correspond with climate data recorded at meteorological stations in the Limpopo River Basin and analyzes farmers' adaptation responses to climate change and variability. A Heckman probit model and a multinomial logit (MNL) model are used to examine the determinants of adaptation to climate change and variability. The statistical analysis of the climate data shows that temperature has increased over the years. Rainfall is characterized by large interannual variability, with the previous three years being very dry. Indeed, the analysis shows that farmers' perceptions of climate change are in line with the climatic data records. However, only approximately half of the farmers have adjusted their farming practices to account for the impacts of climate change. Lack of access to credit was cited by respondents as the main factor inhibiting adaptation. The results of the multinomial logit and Heckman probit models highlighted that household size, farming experience, wealth, access to credit, access to water, tenure rights, off-farm activities, and access to extension are the main factors that enhance adaptive capacity. Thus, the government should design policies aimed at improving these factors.

There is overwhelming evidence that the climate is changing. It is the poorest countries and people who are the most vulnerable to this threat and who will suffer the most. This book shows how increasing urbanization and growing poverty levels mean that it is imperative to ask how climate change might impact on asset accumulation and food security for the urban poor. It demonstrates how these three, often separate foci, can be brought together to frame a holistic urban adaptation approach. Furthermore, although much has been written about climate change, limited evidence exists in southern Africa of how climate change has been integrated in urban planning. The authors explore the urban climate change nexus linking asset adaptation, climate change science and food security through several case study cities. These include Cape Town, George and Khara Hais (South Africa), Lusaka (Zambia), Maputo (Mozambique), Mombasa (Kenya) and Harare (Zimbabwe). The results shed light on how this nexus might be explored from different perspectives, both theoretical and practical, in order to plan for a more resilient future. Climate Change, Assets and Food Security in Southern African Cities comprises ten chapters which focus on southern African cities, with each chapter written by highly experienced academics, research-focused practitioners and professional planners. Although the book concentrates on southern African cities, the insights which are presented can be used to understand other urban centres in low and middle-income countries outside of this region and around the world.

This title was first published in 2003. Recent food shortages in Southern Africa, induced by rainfall variability but compounded by problems of governance and rising food prices, have resulted in massive relief efforts. A recent scientific innovation - supplying farmers with seasonal climate forecasts - has been touted as a way to increase preparedness for such situations. This book examines how climate forecasts are used by the agricultural community in Southern Africa. Based on a workshop funded by the World Bank, it covers a broad set of issues related to the use of seasonal forecasts, including factors that constrain users' capacities to respond. Case studies presented in the book explore how forecasts can potentially increase production and food security among a population highly dependent on agriculture and vulnerable to climate variability. The book reflects on how the production, delivery and uptake of seasonal forecasts might be improved, as well as the limitations to their usefulness, and it should catalyse future thinking and research in this field.
