New evidence this year corroborates the rise in world hunger observed in this report last year, sending a warning that more action is needed if we aspire to end world hunger and malnutrition in all its forms by 2030. Updated estimates show the number of people who suffer from hunger has been growing over the past three years, returning to prevailing levels from almost a decade ago. Although progress continues to be made in reducing child stunting, over 22 percent of children under five years of age are still affected. Other forms of malnutrition are also growing: adult obesity continues to increase in countries irrespective of their income levels, and many countries are coping with multiple forms of malnutrition at the same time – overweight and obesity, as well as anaemia in women, and child stunting and wasting.

Why write a book on macroeconomic policies and their links to agriculture and food security in developing countries? The food price spikes of the years just prior to 2010 and the economic, political, and social dislocations they generated refocused the attention of policymakers and development practitioners on the agricultural sector and food security concerns. But even without those traumatic events, the importance of agriculture for developing countries—and for an adequate functioning of the world economy— cannot be denied. First, although declining over time, primary agriculture still represents important percentages of developing countries’ overall domestic production, exports, and employment. If agroindustrial, transportation, commercial, and other related activities are also counted, then the economic and social importance of agriculture-based sectors increases significantly. Furthermore, large numbers of the world’s poor still live in rural areas and work in agriculture. Through the links via production, trade, employment, and prices, agricultural production is also crucial for national food security. Second, it has been shown that agriculture in developing countries has important growth and employment multipliers for the rest of the economy, and agriculture seems to have larger positive effects in reducing poverty than growth in other sectors. Third, agriculture is not only important for individual developing countries, but it has global significance, considering the large presence of developing countries in world agricultural production and the increasing participation in international trade of those products (these three points will be covered in greater detail in Chapter 1).

Food problems are the order of the day. Solving the problems of hunger and malnutrition, producing and guaranteeing access to healthy food, preserving the environment, valuing local cultures and ensuring citizen participation are some of the many challenges that permeate the dynamics of food systems. This book addresses the role of Latin American public policies and actions in the configuration of healthy and sustainable food systems. Written by scholars specialized in various disciplines (economy, sociology, policy science, etc.) and hailing from ten Latin American countries, it provides a historical overview of national food policies, examines recent policy changes and explores innovative urban and rural experiences at local level. The authors also discuss the challenges of developing specific policy objectives related to sustainable food systems. This book shows how référentiels for public food policies have become more integrated in Latin America and takes a closer look at several promising local initiatives. However, it also highlights the many constraints in fostering sustainable food systems in the region, such as persistent competition among production models, land tenure inequalities and coordination issues among actors and state bodies. It will be of interest to a scientific audience of teachers and food systems professionals, as well as any readers interested in policy dynamics in Latin America.

Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions. The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic. The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition.

Agricultural mechanization in Africa south of the Sahara — especially for small farms and businesses — requires a new paradigm to meet the needs of the continent’s evolving farming systems. Can Asia, with its recent success in adopting mechanization, offer a model for Africa? An Evolving Paradigm of Agricultural Mechanization Development analyzes the experiences of eight Asian and five African countries. The authors explore crucial government roles in boosting and supporting mechanization, from import policies to promotion policies to public good policies. Potential approaches presented to facilitating mechanization in Africa include prioritizing market-led hiring services, eliminating distortions, and developing appropriate technologies for the African context. The role of agricultural mechanization within overall agricultural and rural transformation strategies in Africa is also discussed. The book’s recommendations and insights should be useful to national policymakers and the development community, who can adapt this knowledge to local contexts and use it as a foundation for further research.

Latin America and the Caribbean managed to reduce the number of undernourished by 20 million compared to the year 2000. However, 2018 marks the fourth consecutive year in which hunger shows a continuous increases. Moderate or severe food insecurity in Latin America increased considerably. This increase caused more than 32 million people to join the almost 155 million who lived in food insecurity in the Region in 2014-2016. The Region has shown significant progress in reducing child malnutrition and it is significantly distant and below the global prevalence of malnutrition in girls and boys. However, malnutrition due to excessive weight in the Region is one of the highest in the world and it continues to increase. This year, the Regional Overview of Food Security and Nutrition in Latin America and the Caribbean focuses on food environments and describes some of the main policies that the countries of Latin America and the Caribbean are developing to face the different forms of malnutrition.
