(a)  Explain four roles of government in agricultural development under the following   
headings:
(i)   pest and disease control;
(ii)  marketing of agricultural produce. 

(b)  Give four general problems of land tenure system in agricultural development in West    
Africa.  

(c)List three farm machinery and three farm implements. 

Answer Details

(a)

(i) Pest and disease control: The government can play a role in controlling pests and diseases in agriculture by providing funding for research, regulation of pesticides and other control measures, and educating farmers on best practices for disease and pest management.

(ii) Marketing of agricultural produce: The government can play a role in facilitating the marketing of agricultural produce by providing infrastructure such as roads, storage facilities, and marketplaces, as well as regulating and promoting fair trade practices.

(b) Four general problems of land tenure system in agricultural development in West Africa are:

1. Lack of clear and secure property rights, which can make it difficult for farmers to access credit and investment, and can also lead to disputes over land ownership.
2. Inadequate land registration and mapping systems, which can make it difficult for farmers to prove ownership of their land and can also lead to disputes over land ownership.
3. Traditional land tenure systems that do not provide for individual ownership of land, which can make it difficult for farmers to access credit and investment, and can also lead to disputes over land ownership.
4. Limited access to land, particularly for women and youth, which can reduce the potential for agricultural development and limit the ability of these groups to contribute to the agricultural sector.

(c) Three farm machinery are:

1. Tractor: A large, heavy-duty machine used for plowing fields, tilling soil, and performing other tasks.
2. Combine harvester: A machine that cuts and threshes crops, such as grain or corn, and collects them in a storage area.
3. Irrigation system: Machinery used to distribute water to crops, such as pumps, pipes, and sprinklers.

Three farm implements are:

1. Plow: A tool used to turn over and break up soil in preparation for planting.
2. Disc harrow: A tool used to level and smooth soil, as well as to control weeds.
3. Seed drill: A tool used to plant seeds in a precise and organized manner, ensuring that they are spaced evenly and at the correct depth.
