5 PROBLEMS IN WATERSHED MANAGEMENT.
Problems Facing Watershed Management
Watershed management is concerned with the study and control of how varied human activities affect the relationship between water and other natural resources. Watershed management is studied with the aim of finding solutions posed by human activities as well as achieving sustainable distribution of resources. Third world countries of Africa and the rest of the world have encountered enough challenges that call for watershed management, among them: pollution, Chemicals disposal, and loss of habitat, interruption of water flow, pathogen attacks, and invasion of alien species. However, the main problems contributing to these are:
– Development of industries.
– Interruption of water flow.
– Development of urban centers.
– Poor fishing methods.
– Invasion of alien species.
Development of industries
– Despite the numerous efforts put in by global institutions to reduce pollution through clean technology, Industrial activities are still emitting toxic chemicals, metal deposits, and petroleum products. The consequence of this being an increase in health risks, this is so when fish and wildlife are poisoned and humans consume the fish. In addition, economic stability is shaken when tourism is jeopardized by closed fish beds in Africa and the world as a whole. However, further improvement and legislation can reduce this problem if not solving it.
Interruption of Water flow
– Once flow of natural water flow is interrupted, there is massive loss that is incurred. Among these is alteration or loss of habitat all together, increased soil erosion, Blockage of passage for fish and other aquatic organisms, alteration of water salinity and an overall disruption of ecosystems. This interruption is realized when there is construction of dams, diversion of water for irrigation, development, construction, industry, and household use.
Development of Urban Centers
– Invasion of natural area by human being with the aim of converting them to urban centre has become a major challenge to watershed management. It also possesses a challenge of decline in fish and wildlife because they are forced to migrate and others die. Chemicals, loss of habitat, alteration of water flow and disposal of waste into water resources by human beings adversely affect aquatic ecosystems. This problem can be addressed through legislation, growth, and water management programs.
Poor Fishing Methods
– While fishing is beneficial for trade, food, and economic growth, it is a potential challenge for watershed management. It is so when poor methods of fishing are used. Overfishing and other methods that can results in alteration and damage of fish habitats, also this affect the population of some species and worst, extinction of some species. Communities that depend on fishing are also affected by this activities as well as economic growth of a country. This can be avoided by providing scholarships to community members to prevent further cases of this kind.
Invasion by alien Species
– Both deliberate and accidental invasion of shoots and plants seed or organisms by ships contribute adversely in problems of watershed management. Among the challenges encountered is loss of habitats and decline in fish and other organisms living in water. There is competition created by these alien species, praying on the native one and imbalance of the ecosystem and the threat of extinction f some species.
Although watershed management has played a fundamental role in discouraging the destruction of water resources and campaigning on the risks involved. Challenges still exist, that call for efforts of everybody who cares and communities are supposed to be educated as well as provided scholarships to enable them enhance and learn more.
