Globalisation has brought about a lot of changes in the world economy, leading to the growth of some sectors while adversely affecting others. One of the sectors that have not benefited from the policy of globalisation is the agricultural sector.

Reasons why the agricultural sector has not benefited from globalisation are:

1. Competition from imports: The globalisation of trade has led to increased competition from imports, which has affected the agricultural sector. Many developing countries have been forced to open up their markets to cheaper agricultural imports from developed countries, which has made it difficult for local farmers to compete.

2. Unequal access to markets: The agricultural sector in developing countries has not been able to benefit from globalisation due to unequal access to markets. Developed countries have erected barriers to market access, which has made it difficult for developing countries to export their agricultural products.

3. Subsidies: Developed countries have been providing subsidies to their agricultural sector, which has made it difficult for developing countries to compete. These subsidies have led to the overproduction of agricultural products, which has led to a decline in prices.

4. Lack of infrastructure: Developing countries lack the necessary infrastructure to transport and store agricultural products. This has made it difficult for farmers to get their products to market, which has affected their ability to compete.

5. Climate change: Climate change has also affected the agricultural sector, making it difficult for farmers to produce crops. This has led to a decline in agricultural productivity, which has affected the sector's ability to compete.

In conclusion, the agricultural sector has not benefited from globalisation due to a range of factors, including competition from imports, unequal access to markets, subsidies, lack of infrastructure, and climate change.
