(1) Explain any one man-made process which is responsible for land degradation.
[1 Marks]
Answer: One significant man-made process responsible for land degradation is the practice of intensive agriculture without proper management of soil fertility. When land is consistently used for agricultural production without replenishing the nutrients in the soil, it leads to the depletion of essential minerals and reduces soil quality. This process ultimately results in decreased agricultural productivity and may lead to permanent land degradation, making the land less capable of supporting crops. Over time, this unchecked practice can contribute to the conversion of fertile land into wasteland, as the soil becomes unfit for cultivation due to nutrient loss and degradation of its structure.
Key Points: intensive agriculture, soil fertility management, nutrient depletion, decreased productivity, conversion to wasteland
(2) Explain the meaning of land degradation.
[1 Marks]
Answer: Land degradation refers to the decline in the productive capacity of the land, which can occur either temporarily or permanently. This decline primarily results from insufficient management of soil fertility, leading to issues such as soil erosion, waterlogging, salinisation, and alkalinisation. These factors contribute to reduced agricultural productivity. While not all degraded lands are considered wastelands, unchecked degradation processes could result in land being classified as such. The causes of land degradation can be both natural and human-induced, and they affect the quality of agricultural land, further compounding the difficulties of sustaining agricultural productivity.
Key Points: definition of land degradation; temporary or permanent decline in productivity; causes include soil erosion, waterlogging, salinisation, alkalinisation; impacts on agricultural land management; distinction between degraded land and wasteland; both natural and human-induced factors
(3) Suggest any two measures to solve the problem of land degradation.
[1 Marks]
Answer: To address the problem of land degradation, it is essential to implement sustainable agricultural practices. Firstly, crop rotation can be employed, whereby different crops are planted in a specific sequence over the years to maintain soil fertility and reduce soil erosion. Secondly, the use of organic fertilizers instead of chemical fertilizers can enhance soil health, improve its structure, and prevent salinisation and alkalinisation. These measures can help restore the productivity of degraded lands and ensure long-term agricultural sustainability.
Key Points: Crop rotation-Use of organic fertilizers-Maintenance of soil fertility
