Extracts from Global Agriculture Towards 2050 (link)
The projections show that feeding a world population of 9.1 billion people in 2050 would require raising overall food production by some 70 percent between 2005/07 and 2050. Production in the developing countries would need to almost double.
Experience of countries that have succeeded in reducing hunger and malnutrition shows that economic growth and poverty reduction policies as such do not automatically ensure success: the source of growth matters too. Crosscountry analysis shows that GDP growth originating in agriculture is, on average, at least twice as effective in benefiting the poorest half of a country’s population as growth generated in non-agricultural sectors. This is not surprising as 75 percent of the poor in developing countries live in rural areas and derive significant parts of their livelihoods from agriculture and related activities. For agriculture-dependent countries in particular, agricultural growth is key for overall growth and development and for poverty reduction.
