(This highlight is part of a series ‘The Changing Agricultural Sector” by David Bigman) 
The agricultural sector has a vital role in the life and food security of the majority of the population in the developing countries. Although the recent report of the UNFPA (The State of World Population 2007: Unleashing the Potential of Urban Growth) estimates that by the end of this decade more than half of the world’s population will live in cities and towns, the rural population will still constitute the majority of the population in the developing countries at least until the middle of this century. In Africa and Asia the urban population is expected to double between 2000 and 2030. In the coming decade, however, more than half of the African population and more than three quarters of the African poor will still live in rural areas and depend on agriculture for their livelihood.
The focus of the World Bank's upcoming 2008 World Development Report on agriculture is not surprising given the continued central role of this sector in the developing countries in general and in the least developed countries (LDCs) in particular. The need to focus on agriculture is obvious for two fundamental reasons:
First, the large share of the agricultural sector in the national income and employment in most developing countries gives the agricultural sector a predominant and unique role in raising the standard of living and reducing poverty.  At the same time, its strong pro-poor growth linkage to other sectors and to employment gives the agricultural sector a pivotal role in raising farmers' incomes and increasing food security in these countries in general and among the rural population in particular.
Second, the methods and organization of agricultural production and trade are still going through far reaching changes in all countries. They include changes in production technologies, in the organization of the entire supply chain, in agricultural trade policies – despite the seeming failure of the Doha Round, in the impact of the Gene Revolution in production, and in the impact of environmental factor in determining the countries’ comparative advantage in trade. These changes that take place at accelerating pace affect this sector to the extent that we must re-valuate costs and benefits and re-evaluate also of some of the well established axioms that are traditionally associated with the function of the agricultural sector and its effects on growth, poverty and income inequality in the developing countries.

Employment created by the many businesses in the supply chain enables still more people to live a decent life. Hunger declines and the quality of rural life improves.
