Land degradation is the decline in the quality of land due to various factors such as soil erosion, deforestation, and overgrazing. It has a number of negative effects on the environment and human society. Here are a few points outlining the effects of land degradation:
Loss of biodiversity: Land degradation can lead to the loss of biodiversity as it reduces the ability of the land to support a diverse range of plants and animals. This can have a knock-on effect on the rest of the ecosystem, leading to a reduction in the number of species present in the area.
Decreased crop yields: Land degradation can also lead to decreased crop yields as the soil becomes less fertile and less able to support plant growth. This can have a major impact on the livelihoods of farmers and communities who rely on agriculture for their income.
Increased risk of natural disasters: Land degradation can increase the risk of natural disasters such as landslides, floods, and droughts. This is because the soil becomes less able to hold water, leading to increased erosion and the likelihood of landslides. Similarly, the lack of vegetation can contribute to drought conditions.
Increased poverty: Land degradation can lead to increased poverty as it reduces the productivity of the land and the ability of communities to earn a livelihood. This can have a long-term impact on the well-being of individuals and communities, leading to a cycle of poverty.
Negative impact on human health: Land degradation can also have negative impacts on human health, particularly in areas where people rely on the land for their food and water. Poor soil quality and reduced crop yields can lead to malnutrition and other health problems.
Overall, land degradation has a number of negative effects on the environment and human society. It is important to take steps to prevent and reverse land degradation in order to protect the health of the land and the people who depend on it.
Land degradation: Multiple environmental consequences and routes to neutrality
Floods may basically be due to unusually heavy rainfall over short durations. There is not enough organic activity in the soil to absorb the water. This causes air pollution, drinking water contamination, and wildfires. Unless they are aided by international organizations, some countries will need to borrow to solve these problems and may never be able to recover from debt. Suitable for cultivation, II.

Not as trade policy reforms on their own but a panacea for environmental damage, with comparative advantage in land degrading crops, greater trade openness without complementary environmental protection policies may lead to rapid worsening of land degradation. Requires good soil management practice, III. Definite care is needed to put back the lost energy through organic sources. The United States is quickly lakes and reservoirs are contaminated by runoff and pollutants nationwide. Biodiversity is important for maintaining the balance of the ecosystem in the form of combating pollution, restoring nutrients, protecting water sources, and stabilizing the climate. There are no trees. These are: i Loss of fodder and forage production, decline in production of timber.
Particulates land on leaves, blocking carbon dioxide uptake and photosynthesis resulting in weakened flora ecosystems. It can take place in any sphere of the environment. Soil erosion and land degradation through various means further affect the physical viability of the soil profile and the environment in terms of solid, water, air ratio as well as chemical and biological balances. It is interesting to note that the cause of floods in the Indo-Gangetic basin is not only the excessive rainfall and snowmelt on the hills but also the inability of the right bank tributaries of the Ganges to drain in time and the inability of the vast alkaline area to absorb and use the onsite rainfall. Lessons and conclusion Over the years, there has been a progressive change in the approach to agricultural practices from crop substitution to integrated farming system.
What is Land Degradation? Causes & effects of Land Degradation
It can be prevented by formation of ridge and furrow during irrigation which lessens run off. Project-based payment for environmental services schemes introduced in Calabar South is meant to provide a means of paying compensation to farmers who desist from environmentally undesirable activities. It is the gradual formation of a desert in a place that was once no desert. The concept of land degradation was considered in four ways which includes, the effect on the soil productivity and the environment around, decline in the land usefulness, loss of bio-diversity, shifting ecological risk and a reduction on the land productive capacity. The destruction of the forests is mainly a result of clearance for agriculture. The search for fuel wood, the growing frequency and severity of forest fires, are also taking their toll.
What are the adverse effects of land degradation ?
Scent leave 45 24 10. Some of these activities and processes are effluent discharge, gas flaring, mining, oil exploration, fossil fuel combustion, and improper disposal of waste such as radioactive waste, minerals, and oil. Thus, the costs of soil erosion include a wide variety of components of importance to man. This eroded material carries several valuable nutrients along With it, which are lost forever. The GEF recognizes that all productive landscapes, from the drylands of Africa and Asia to the sub-tropical grasslands of South America, and temperate forests in Europe must be managed carefully and sustainably. United Nations Convention to combats desertification, 1996.
Patterns of degradation vary in Calabar South according to agro-ecological conditions, farming systems, levels of intensification, and resource endowments, but this also interact with social and economic systems. They may also linger in the environment for many years. What is keeping you alive is microbial life on all levels. Criteria for designating different classes of land degradation into Low, moderate, high are generally based on soil properties rather than their impact on productivity as presented in figures 4, 5, and 6. Let us find out what surface runoff means.
Effects of Land Degradation on Soil Fertility: A Case Study of Calabar South, Nigeria
The cost of reclamation, or restoration to productive use, of degraded soils is invariably less than the cost of preventing degradation before it occurs. But in places like Spain, California, Canada, and the Russian Federation, a fire occurs as a result of lightning. Water pollution is the introduction of pollutants and particulate matter into water bodies such as lakes, rivers, and seas. The eight productivity classes are: I. Sugar cane 42 21 9.
Environmental Degradation: Causes The causes of environmental degradation are many, but there are 2 main reasons that the environment suffers degradation of all types. Moderate restrictions in use, and VIII. The productivity of crop land lost annually is given in the following Table 12. For environmental taxes, e. This marked a major departure from the previous approach.
