This book presents climate change as a global phenomenon which affects the entire food chain. Many studies analyzing environmental impacts of food systems confirm significant effects of food production on climate change. Most of them associate primary production with emission of greenhouse gasses identified as one of the causes resulting in warming the atmosphere and global climate effects. A wider perspective shows that the food chains start at farms with consumers being at the end of the pipeline. This approach emphasizes the role of the entire food chain highlighting different kinds of environmental impacts affecting climate change. On the other side, temperature changes and variations of precipitation patterns, together with extreme weather events and water reduction, are recognized as predictors for producing less food, decreased food quality, new food safety risks, biodiversity losses, and depletion of resources associated with food production in modified circumstances. Last but not least, these effects introduce new threats known as food security where some assumptions stress that almost one billion of people are hungry not receiving enough food as a result of climate changes. As a result, the UN highlights the need for combating climate change and promotes sustainable (food) consumption and production. Based on the perceived need to promote and disseminate information on climate change related to food system, the “Handbook of Climate change across the food supply chain” is being produced. The publication compiles information, experiences, practical initiatives, and projects around the subject matter and makes it available to a wide audience. It is expected that the “Handbook of Climate change across the food supply chain” makes many benefits of climate service clearer and, inter alia, leads to an increase in the demand for such important services.

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.

Water Productivity and Food Security: Global Trends and Regional Patterns, Volume Three reviews the need for water productivity improvements in agriculture, addressing three distinct questions pertaining to agricultural water productivity improvement in developing countries, including what are the regions where water is a limiting factor for raising agricultural outputs and water productivity improvements, what are the technological measures in irrigation that can raise agricultural water productivity and result in water saving at various scales, and what opportunities exist in the developing economies of South Asia and Africa for raising water productivity and improving water economy at basin scale. This book provides a framework to characterize river basins based on water availability, water supplies, water uses and water demands to ascertain the need and measures available for improving crop water productivity that would be effective at various scales, i.e., plant-level, plot-level, irrigation system level and basin level. This is an essential reference for anyone interested in water management and agriculture. Presents clear explanations of the physical and technical measures that can be adopted to improve productivity of water in agricultural production under different basin conditions Offers physical strategies for improving water productivity in agriculture in different agroecological regions, along with the institutional and policy measures that affect them Includes methodologies for assessing the food security challenges of individual nations using empirical analysis and global datasets

Climate change is expected to influence several productive sectors, the most significant of which is agriculture. Agriculture comprises an important sector of the global economy that includes crops, livestock, and seafood. Agriculture, aquaculture, and fisheries are closely linked to the climate, with changes in climatic conditions able to drastically affect animal and plant productivity, which in turn has a direct impact on human well-being. Impacts of Climate Change on Agriculture and Aquaculture is a critical scholarly publication that provides an integrated assessment of climate change impacts on agriculture, aquaculture, and fisheries and explores a set of strategies to secure sustainable food security. While highlighting the associations between climate change, food security, and socio-economic development, the book establishes an inventory of good agricultural practices for the adaptation to climate change and presents solutions for making agricultural and food systems more sustainable. Featuring a wide range of topics such as carbon sequestration, ecosystem management, and desertification, this book is ideal for agriculturalists, environmentalists, fisheries, marine biologists, ichthyologists, government officials, academicians, policy makers, scientists, professionals, researchers, and students.

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.

"This paper uses a computable general equilibrium approach to simulate two opposing views describing regional trade agreements either as building blocks for or stumbling blocks to multilateral trade liberalization. This study focuses on the free trade agreement (FTA) between the Economic and Monetary Community of Central Africa (CEMAC) and the European Union (EU). Results show that although a regional trade agreement may slightly raise welfare among the members of the agreement, the cost to nonmembers can be high. In this paper we argue that multilateral liberalization and a regional free trade agreement between the EU and CEMAC are not mutually exclusive. Regional trade agreements should be complementary and consistent with a multilateral agreement, not an attempt to replace it. The regional breakdown in our design considers 14 regions, allowing for country-specific analysis for one least-developed country (Democratic Republic of Congo) and one non-least-developed country (Cameroon). Multilateral liberalization amplifies welfare gain for Cameroon. The Democratic Republic of Congo, with its weaker institutional capacity, is affected negatively. An EU-CEMAC FTA without multilateralism produces gains for both Cameroon and the Democratic Republic of Congo. The gain for Cameroon is, however, moderate compared with that achieved when the EU-CEMAC FTA is accompanied with a multilateral agreement."--Authors' abstract.

"Migration can serve as an outlet for employment, higher earnings, and reduced income risk for households in developing countries. We use the 2004-2005 Human Development Profile of India survey to examine correlations between the receipt of remittances from internal migrants and human capital investment in rural areas. We employ a propensity score-matching approach to account for the selectivity of households into receiving remittances. We interpret the results conservatively due to the cross-sectional nature of the data. We find a positive correlation between remittances received from internal migrants and the schooling attendance of teens. The magnitude of the correlation is greater when focusing on low-caste households, and male schooling attendance in particular becomes more positive and statistically significant. Our findings provide a basis for establishing future research in the areas of migration and social protection in India."--Authors' abstract.
