The implication is that the generation of additional employment in response to a positive demand shock in agriculture is largely limited to the sector itself, while in other developing countries many jobs are created outside agriculture. This is partly due to the lack of input supply, such as fertilizers and infrastructure services, but is also due to the subsistence nature of agriculture in some of these economies. However, it also means that potential benefits of agricultural productivity growth will be greater than the current production structure suggests, as the backward linkages with other sectors also evolve with agricultural development.
