The proportion of agriculture in the economy and in the workforce varies widely by country. The area remains economically important especially in Africa, even if the comparison between Ethiopia and Congo, for example, reveals very different profiles in terms of employment created. Even in countries that still have a strong rural agricultural workforce such as Ethiopia and Kenya, the agricultural structure itself and the links with other sectors explain the varying contributions of the sector to the creation of national wealth. Finally, large economically important countries such as India or China, where agriculture represents a small proportion of the GDP, retain a significant portion of their labour force in agriculture. All of these factors reflect the difficulty of addressing the overall issue of agriculture and of proposing strategies for the future.
