Causes of watershed degradation
Watershed degradation is a significant environmental issue that has a range of negative impacts on the health and wellbeing of both human and natural systems. It refers to the degradation of the land, water, and natural resources within a watershed, which is an area of land that drains all the streams and rainfall to a common outlet such as a river, lake, or ocean. Watershed degradation can occur for a variety of reasons, some of which are outlined below.
One of the main causes of watershed degradation is land use change. This can occur through the conversion of natural areas to agricultural or urban land use, which can result in the loss of vegetation, soil erosion, and the disruption of natural hydrological processes. Land use change can also lead to the alteration of local climate conditions, as well as the introduction of non-native species that can alter the local ecosystem.
Another significant cause of watershed degradation is pollution. This can occur through the release of chemicals, nutrients, and other contaminants into the environment, which can have negative impacts on the quality of the water and soil. Pollution can also affect the health of the local flora and fauna, as well as the wellbeing of humans who rely on the resources of the watershed.
Deforestation is another major cause of watershed degradation. The removal of trees and other vegetation can lead to soil erosion, reduced water retention, and the alteration of local climate conditions. Deforestation can also affect the ability of the watershed to support a diverse range of plant and animal species, which can have negative impacts on the overall health and resilience of the ecosystem.
Overgrazing and poor agricultural practices can also contribute to watershed degradation. Overgrazing can lead to the loss of vegetation and soil erosion, while poor agricultural practices can result in the introduction of pollutants and the overuse of chemicals, which can have negative impacts on the quality of the water and soil.
Climate change is another factor that can contribute to watershed degradation. Changes in weather patterns, such as more frequent and intense storms, can lead to soil erosion and the alteration of natural hydrological processes. The impacts of climate change can also affect the overall health and resilience of the local ecosystem, as well as the availability of natural resources.
In conclusion, watershed degradation is a complex issue that is caused by a range of factors, including land use change, pollution, deforestation, overgrazing, poor agricultural practices, and climate change. It is important to address these issues in order to protect the health and resilience of natural systems and to ensure the sustainable use of natural resources.
Top 20 Causes of Environmental Degradation
Climatic changes also lead to a distorted hydrological cycle that results into more greenhouse gasses being in the atmosphere and a whole lot of other things like the imbalance of snow and rain and increased evapotranspiration. This is one of the major impetuses behind the development of alternative, clean sources of energy, including solar and wind. The major causes of the environmental degradation are modern urbanization, industrialization, over-population growth, deforestation etc. Nutrient pollution, on the other hand, is any pollution caused by fertilizers and nutrients. Environmental degradation is a result of majorly socio-economical, technological, and institutional activities.
What are the causes of watershed deterioration?
However, it destroys habitats and changes the landscape and soil composition forever. A more basic cause of environmental degradation is land damage. Territorial Conflicts Conflict usually causes harm to the environment. Household-level determinants of soil and water conservation adoption phases: evidence from North-Western Ethiopian Highlands. Poor water management both regionally and globally is a major problem when it comes to protecting water quality. For example, through farming practices, excessive amounts of fertilizers and pesticides are used.
Causes, Effects and Solutions to Environmental Degradation
Journal of Flood Risk Management, 7 2 , 118—127. This is because the overabundance tends to cover a massive water surface, is an addition to preventing sunlight from accessing the plants underwater. Environmental surroundings get to be divided when technological advancement splits up areas of land. The runoff includes things such as chemicals and salts mostly from farms, health care points, fertilizers, lawns, salts, and chemicals Greenberg, 2005 p558. Would you enjoy spending your vacation on this beach? India has about six million hectares of saline land. Land use changes and forest degradation in a Himalayan watershed: analysis and policy alternatives 1.
Water Quality Degradation, Causes And Consequences Research Paper Example
Environmental degradation is all around us. Ground water brings the salts of soil in dissolved state up to the surface where they form a layer or sheet of salt after evaporation. The growing problem of pollution of the river ecosystem has necessitated the monitoring of water quality. Tell students they will complete a reading assignment to learn more about water quality degradation. Water pollution is caused due to release of toxins from factories and home to the water bodies. Loss of Biodiversity 3. 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.
What are the Causes of Water Pollution?
Landslides are very important causes of environmental degradation. The water gets polluted by agricultural runoff, waste treatment plants, chemical leaching, stormwater runoff, and garbage. As a result, food chain tends to be disrupted at great levels. Most pollution types affect the immediate environment facing the source directly. Almost 70% of water available worldwide is used for agriculture with this amount rising in countries like Pakistan and India. Environ Dev Sustain 19 2 :443—459. If water on the planet were to be divided equally, 5000 to 6000 m3 of water should be available for everyone in the world per year.

ADVERTISEMENTS: The word pesticides includes any form of chemical used for the control of unwanted herbaceous plants herbicides , woody plants arboncides , insects insecticides or any chemical that has biocidal activity affecting rodents, arachnids or any other population. Conclusion Environmental degradation is a serious problem for humanity. Under natural condition, soil erosion due to these causes is a natural process. Marine degradation is a new concern with the development of tidal power technologies. When industrial waste is not treated properly or worse, not treated at all , it can very easily pollute the freshwater systems that it comes into contact with. Large swaths of the This happens when the water along the shoreline becomes chemically imbalanced. This includes the species that live in the soil.
Causes and Effects of Watershed Degradation
Polluted drinking water can also cause treatment costs to rise, which in turn makes the cost of drinking water rise as well. Cham: Springer International Publishing. The degree of the environmental impact varies with the cause, the habitat, and the plants and animals that are found in these habitats. When these habitats become polluted, by rainwater that drags pollutants into water, it proves to be catastrophic for the aquatic organisms. Water degradation Good water quality is crucial for human life as well as for the life of many animals.

They may also be more willing to participate in radical activities due to their desperation.
