NOTE
ENVIRONMENTAL FACTORS THAT AFFECT AGRICULTURAL PRODUCTION
Environmental factors affecting agricultural production can be grouped into:
1). RAINFALL: Is defined as the amount and distribution of water precipitation within a given time in a given area.
RAINFALL DISTRIBUTION AND PATTERN: West Africa is known for its high temperature throughout the year. It is brought about by the south- west monsoon trade wind blowing from the Atlantic Ocean.
The wind blowing from the ocean to the inland drops some water. A narrow part of the coast has rainfall throughout the year against the rest of the region. As we move from the coast, the amount of rainfall decreases. By the time the wind get to the northern part of the country, there is little or no moisture left in it. Here, less rainfall is experienced per year. In the coastal area, the raining season ranges from 8 months to the all year round while in the north, raining season lasts only 3 to 4 months. The moisture required affects crop and livestock production. In the coastal areas more of the southern parts, crops adapted to heavy rainfall predominantly trees, yam, maize, rice, fruit, banana, etc. Much animal rearing does not take place here due to high humidity rate which exposes the animals to tsetse fly infection.
Only animals which can resist the attack of trypanosomiasis can be seen in this area. Examples are N’dama and Muturu breeds of cattle, dwarf sheep and goat, poultry. Those crops that can thrive well in the northern part with little rainfall or resistance to drought are guinea corn, millet, groundnut, cowpeas, cotton etc.
IMPORTANCE/EFFECT OF RAINFALL
2). TEMPERATURE: Is defined as a measure of the heat energy which a body contains or the degree of hotness or coolness of a place, at a point in time. Temperature varies from the coastal areas to extreme north. In the dry season, temperature is not high in the coaster area as against the north which is extremely high.
IMPORTANCE/EFFECTS OF TEMPERATURE
1 It affects the distribution of crops and animals.
3). SUNLIGHT
IMPORTANCE/INFLUENCE
4). WIND
INFLUENCE/IMPORTANCE
1) High wind may cause wind erosion.
2) It aids seed and fruit dispersal
3) It can aid pollination and spread of disease.
4) It helps in the distribution of rainfall and changes in seasons e.g. rainy and dry season
5) High wind velocity causes damages to crops.
