Policy brief No. 1. In recent years, food consumers have become in- creasingly aware of and concerned about the sa- fety of food products. As a response, public and private actors have introduced different standards to ensure that food safety reaches the degree de- manded by consumers. Developing countries often lack the institutional capacities and financial and non-financial resources to comply with standards.
Policy brief No. 3. Adequate nutrition is a crucial welfare dimension. Malnutrition at a young age can have severe con- sequences for a person’s development of human, social, and economic capital. Also in later phases of one’s life, malnutrition can severely affect health and restrict productivity as well as overall quality of life. Efforts to improve nutrition among rural populations, for example through more diversified diets, are therefore key components of many rural development agendas, especially in Africa where undernutrition is still a large public health prob- lem.
The latest turmoil of production and price volatility in the global food sector has put agriculture back to the top of the development agenda. Population growth, changing consumer preferences, bioenergy demand and climate change are some of the huge challenges for agricultural production today and in the future. In the last decades, productivity has been constantly improved through the introduction of improved crop varieties and the greater use of mechanization, irrigation, chemical fertilizer and pesticides.
In Sub-Sahara Africa, adoption rates of improved crop varieties remain relatively low, which is partly due to farmers’ limited access to information. In smallholder settings, information often spreads through informal networks. Better understanding of such networks could potentially help to spur innovation and farmers’ exposure to new technologies. This study uses survey data from Tanzania to analyze social networks and their role for the spread of information about improved varieties of maize and sorghum.
