Disease-related malnutrition is a global public health problem. The consequences of disease-related malnutrition are numerous, and include shorter survival rates, lower functional capacity, longer hospital stays, greater complication rates, and higher prescription rates. Nutritional support, in the form of oral nutritional supplements or tube feeding, has proven to lead to an improvement in patient outcome. This book is unique in that it draws together the results of numerous different studies that demonstrate the benefits of nutritional support and provides an evidence base for it. It also discusses the causes, consequences, and prevalence of disease-related malnutrition, and provides insights into the best possible use of enteral nutritional support.

Poor people in developing countries are often affected by droughts, floods, illness, crop failure, job loss, and economic downturns. Much of their energy goes into coping with these shocks and into day-to-day survival. While insurance and credit markets, combined with widespread social security, provide an important cushion against poverty in rich countries, the need for immediate survival may lock the poor into persistent poverty in developing countries.The poor in developing countries do have informal mechanisms to cope with risk and misfortune. These are based on income diversification, risk avoidance, self-insurance by saving together with family, and community-based mutual assistance. Nevertheless, the scope of these mechanisms remains limited. Repeated individual-specific shocks such as illness or pests, or covariate risks associated with drought, flood, or recession, undermine the ability of individuals and their families to cope withrisk.We now know much more about vulnerability to risk and how poor people cope. Even more importantly, we have learned much about the large long-term consequences of these risks, which condemns many to persistent poverty and excludes them from economic growth. But there is much that can be done. The micro-level studies that underpin this book offer new insights on how effective public action could be more effective in protecting the vulnerable against persistent poverty. Policy should focus onproviding a comprehensive menu of ex-ante and post-crisis protection mechanisms, including new forms of insurance, savings, safety nets, and the means to strengthen the poor's asset base. Local communities have a big role to play: public funds should not be used to replace indigenous community-basedsupport networks; rather they should be used to build on the strengths of these networks to ensure broader and more effective protection.With numerous thematic chapters and case studies of both best practice and of failure, from a mix of low-income and middle-income countries across the developing world, this book evaluates alternatives in widening insurance and protection provision, and makes an important contribution to the topical field of insurance and risk.

Some agricultural practices, such as irrigation, have the potential to buffer seasonal dietary gaps and thus improve diets, particularly for subsistence farmers but also for rural and urban households that purchase irrigated produce from local markets. While the seasonality of households and children’s diets is well documented, little is known about the seasonality of women’s diets and the influence of irrigation. Using longitudinal data from Ethiopia, this study characterized women’s diet over time and evaluated the potential implications of seasonality and irrigation on women’s diet. Women’s dietary diversity was low (3-4 out of 10 food groups) and exhibited high seasonal variability (P<0.05). Diets were predominantly plant-based, with little consumption of nutrient dense foods, such as fruits and animal source foods. High seasonal variability in energy, protein, vitamin C, calcium, iron, and zinc intakes were observed (P<0.01). Irrigators were more likely to meet the minimum dietary diversity for women (MDDW), had higher energy and calcium intake, and lower prevalence of anemia, than women from non-irrigating households (P< 0.05). No cases of malaria were reported from the three rounds of screening. Our preliminary findings suggest that there is high seasonal variation in women’s diet, but this can be partly offset by irrigation practices.

Seasonality is a severe constraint to sustainable rural livelihoods and a driver of poverty and hunger, particularly in the tropics. Many poor people in developing countries are ill equipped to cope with seasonal variations which can lead to drought or flood and consequences for agriculture, employment, food supply and the spread of disease. The subject has assumed increasing importance as climate change and other forms of development disrupt established seasonal patterns and variations. This book is the first systematic study of seasonality for over twenty years, and it aims to revive academic interest and policy awareness of this crucial but neglected issue. Thematic chapters explore recent shifts with profound implications for seasonality, including climate change, HIV/AIDS, and social protection. Case study chapters explore seasonal dimensions of livelihoods in Africa (Ethiopia, Kenya, Malawi), Asia (Bangladesh, China, India), and Latin America (Peru). Others assess policy responses to adverse seasonality, for example through irrigation, migration and seasonally-sensitive education. The book also includes innovative tools for monitoring seasonality, which should enable more appropriate responses.
