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.
What is Land Degradation? Causes & effects of Land Degradation
Vegetable 52 38 7. Marine degradation is a new concern with the development of tidal power technologies. Sugar cane 42 21 9. This leads to migration towards cities and towns, causing social problems related to unplanned urbanisation. Other examples of marine degradation are dead zones and the loss of coral reefs.
Effects of Land Degradation on Soil Fertility: A Case Study of Calabar South, Nigeria
Class I is flat or nearly flat land suited for cultivation but a few conservation practices are necessary. Palgrave Macmillan and the World Bank; Hanisphire, UK, and Washington DC. The equipments listed below in table 1 were used in analyzing soil properties. Air, water, and soil are all resources that are vulnerable to depletion through overuse, mineral deposits are also prone to depletion. Storage of toxic waste is also a big problem.
What are the adverse effects of land degradation ?
Most of our natural resources such as water, minerals, air, land, and living organisms are in a serious state of degradation. Land degradation is a serious issue but hardly any govt. This disaster originated from strong thunderstorms and emerges as a rotating, funnel-shaped cloud with winds of about 300 mph. Environmental degradation is the exploitation of natural resources and the destruction of the environment to get them. Tsunamis are catastrophic ocean waves, usually caused by a submarine earthquake, an underwater or coastal landslide, or a volcanic eruption Tsunamis lead to submerging of properties and land surfaces, contamination of the water environment, gas leaks and fire incidents, human fatalities, and loss of aquatic life. It hastens the loss of highly productive farmland, affects energy demand, alters the climate, modifies hydrologic and biogeochemical cycles, fragments habitats, and reduces biodiversity.
[PDF Notes] What are the adverse effects of land degradation ? 2023
This Meningitis is a disease that results from enhanced global warming 2. If this should continue, there would be a high negative impact on a small temperature increase. Communities are more susceptible to future land degradation as well as to socioeconomic and political forces due to the long-lasting effects of land degradation, such as soil erosion and contamination. Sweet potatoes 33 15 14. This may take decades for quality clean-up of the affected site. The productivity of crop land lost annually is given in the following Table 12.
Land degradation: Multiple environmental consequences and routes to neutrality
In the case of subsidies, their relaxation creates fiscal savings that provide an opportunity to compensate farmers, who are often extremely poor. We can also do more. 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. No restrictions in use, VII. The key action required to combat land degradation in Calabar South is to develop a long-term land conservation plan which will provide the necessary continuity of the approach. Developed countries have access to fresh water at all times, but it is often contaminated with chemicals, pharmaceuticals, bacteria, lead, mercury, arsenic, and even radon. It later spread to Russia, other Asian countries, Pan-African countries, and the new industrial countries.
Landslides are usually triggered by natural hazards such as earthquakes, volcanic eruptions, heavy rain storms, or cyclones. Deforestation is also widespread, about 6 million hectares of forest are lost each year. What is keeping you alive is microbial life on all levels. Why has this happened? But, it can also happen from deforestation, over-cultivation and over-grazing, and other human causes. Annual rate of soil loss into the sea through erosion is 5mm. Combating land degradation and restoring degraded land is an urgent priority to protect the biodiversity and ecosystem services vital to all life on Earth and to ensure human well-being.
How it is affected globally? Our rivers, lakes, ponds, and wells are not sources of water. And all that consumption contributes to ecological degradation, increased conflicts, and a higher risk of large-scale disasters like pandemics. We will consider the effects of land degradation one by one, Surface Runoff and Floods Most of the soil is lost through the surface runoff. Ozone Layer Depletion and Climate Change The constant and prolonged release of certain gases such as chlorofluorocarbons and hydrochlorofluorocarbons into the stratosphere causes The ozone layer is responsible for protecting the earth from harmful ultraviolet rays. Beyond the specific causes of land degradation, the general causes of land degradation are usually either: — physical causes, or chemical causes — natural causes, or human causes — direct causes, or indirect causes Soil erosion for example happens via wind, and water from rain — which are natural causes. Environmental degradation is an all-encompassing concept that covers a variety of issues and comes in different forms.
Expanding on the efficiency of agricultural products point, — Consider Alternate Forms Of Food Production Other Than Traditional Land Based Agriculture We may also look at alternative forms of food production other than conventional agriculture, such as This cuts down on the need to use land and soil in some ways. Water yam 45 14 10. What is Environmental Degradation Definition? Climate change, deforestation, biodiversity loss, dead zones, genetic engineering, irrigation concerns, pollution, soil degradation, and waste are only a few of the broader environmental problems agriculture contributes to. These have the potential to harm coastal food supplies, limit coastal production, and deteriorate aquatic habitats. Heavy tilling, multiple harvests and abundant use of agrochemicals have increased yields at the expense of long-term sustainability. Rice 49 20 9.
Implementing Ecological Restoration Projects and Sustainable Land Management Practices India has successfully implemented nature-based solutions as preventative or curative countermeasures to environmental issues. The amount of biomass in the soil has come down by around 80% in the last 50 years. Water pollution is the introduction of pollutants and particulate matter into water bodies such as lakes, rivers, and seas. Custom design both a short and long term strategy based on the causes of each type of land and soil degradation Once causes have been identified in an area, prevention strategies and solutions can be based around those causes. This means the next generation we produce will be less than us.
Because reefs are located off-shore from continental areas they are greatly exposed to human activity. Intensive land management under any of the primary production system, except multi-tiered forest, invariably leads to exhaustion of the land. The environmental consequences of land degradation are vast, including amplified soil losses, water quality deterioration, biodiversity decline and degradation of ecosystem services and corresponding values, especially if actual land uses disrespect capability natural use , in which cases land is in a state of environmental conflict. But the level of degradation that has happened in the last 70 years is scary. Hurricanes can directly kill animals or have an impact on them indirectly by altering habitat and food availability due to strong winds, storm surges, and heavy rain.
