Vulnerability and the Impact of Climate Change in South Africa's Limpopo River Basin


Book Description

This paper uses farmers' responses to exogenous weather shocks in South Africa's Limpopo River Basin to gauge how farmers are apt to respond to future climate change-induced shocks, in particular drought. Droughts are expected to increase in both frequency and intensity as a result of climate change. This study examines the costs of drought today and who it affects the most, in an effort to guide policy adaptations in the future. A combination of descriptive statistics and econometric analysis is used to approximate the potential impact of droughts on rural South African households. This paper also estimates household vulnerability. After controlling for household heterogeneity using propensity score matching, it is noted that there is no statistically significant impact of droughts on income, thus suggesting households have already adapted to living in a drought-prone environment. The types of households that were more vulnerable to climate shocks are analyzed using two measures of vulnerability: the probability of falling below income of 7,800 South African Rand (R), and the probability of income falling below 16,000 R. Residents of the Limpopo province were the least vulnerable under both metrics. Setswana and SeSwati households were more vulnerable than other ethnic groups. Households that do not own livestock and households that rely on rainfed agriculture were also more vulnerable than other households.




Facing the Facts


Book Description

Africa's high dependence upon natural resources makes the continent particularly vulnerable to changes in the availability of water as a result of climate changes. In this study, the vulnerability of water resources to environmental change is assessed on a river/lake/groundwater basin scale for the Southern, Eastern, Western and Northern African regions.




Understanding Farmers' Perceptions and Adaptations to Climate Change and Variability: The Case of the Limpopo Basin, South Africa


Book Description

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.

From climate risk to resilience: Unpacking the economic impacts of climate change in Mozambique


Book Description

Mozambique is already vulnerable to extreme weather events and climate change is projected to exacerbate their frequency and intensity. The occurrence of cyclones and flooding has increased in recent years and the trend is expected to continue. The country’s coast—where 60 percent of the population, the three biggest cities, and critical infrastructure are situated—is most exposed to climate change-related risks, including damage from cyclones and projected sea level rise. Densely populated and low-lying regions, such as Zambezia, Nampula, Sofala, and Maputo Provinces, are particularly exposed to risks from flooding. More broadly, climate change is projected to increase average temperatures across the country and to result in higher variability in precipitation, especially in the south. The most critical economic sectors vulnerable to climate change in Mozambique are agriculture, transport, and potentially energy. In agriculture, maize is likely to be the most affected key crop. This can pose risks to food security (alongside expected higher food inflation because of climate change), given maize’s widespread cultivation and role in nutrition. The impact on other crops is likely to be more limited, and to a large extent driven by damages from increased frequency of extreme weather events. This could exacerbate challenges in the sector, which is already constrained by low productivity and limited arable areas. That said, climate change could create some opportunities; for example, rice yields are projected to improve. Most studies project agricultural production in the central region to be most adversely affected by climate change, albeit the impact varies by crop and within regions. Mozambique’s transport infrastructure is highly vulnerable to climate change due to the projected increase in flooding, the low proportion of paved roads, their limited interconnectivity, and the vulnerability of ports to cyclones and storm surges. Damages to Mozambique’s transport sector are likely to have knock-on effects to other sectors and can have significant regional implications, as the country serves as a conduit for landlocked neighboring countries. Infrastructure damages, alongside the projected coastal erosion, may severely affect the tourism sector. Furthermore, Mozambique’s high dependence on hydropower exposes it to losses from rainfall variability, which is expected to increase. The country’s largest hydropower plant is located downstream on the Zambezi River, which various studies project to dry up due to climate change. Increased water use in upstream countries (such as because of greater irrigation needs and in response to growing populations) could also pose risks to Mozambique’s hydropower sector.




Climate Change Vulnerability in Southern African Cities


Book Description

In recent decades, extreme rains and drought have struck urban regions in Africa like never before. Nevertheless, limited information is available on which to base development of early warning systems, identification of high-risk zones and formulation of local action plans. This book is about how to build the knowledge necessary for planning adaptation to climate change in Sub-Saharan cities. It brings together lessons learned from international development actions conducted by a number of scholars in disciplines ranging from meteorology and hydrogeology to urban planning and environmental management. Selected methods to assess the impacts of extreme weather and ecological stress are presented along with possible approaches to improve the adaptive capacity of Sub-Saharan cities through institutional measures at the local government level. The book is addressed to graduate students, researchers and practitioners interested in enhancing their knowledge and skills in order to integrate climate change into applied research and development projects in urban Africa.




Climate Change Epistemologies in Southern Africa


Book Description

This book investigates the social and cultural dimensions of climate change in Southern Africa, focusing on how knowledge about climate change is conceived and conveyed. Despite contributing very little to the global production of emissions, the African continent looks set to be the hardest hit by climate change. Adopting a decolonial perspective, this book argues that knowledge and discourse about climate change has largely disregarded African epistemologies, leading to inequalities in knowledge systems. Only by considering regionally specific forms of conceptualizing, perceiving, and responding to climate change can these global problems be tackled. First exploring African epistemologies of climate change, the book then goes on to the social impacts of climate change, matters of climate justice, and finally institutional change and adaptation. Providing important insights into the social and cultural perception and communication of climate change in Africa, this book will be of interest to researchers from across the fields of African studies, sociology, anthropology, philosophy, political science, climate change, and geography.
