Effects on the Terai Ecosystem and its Mitigating Measures
Due to human activities, development, construction and modernization, the ecosystem of Terai region has been adversely affected.
Some of the efforts and mitigating measures are as follows.
-
Use of forest and its protection
The density of population is high in this region.In this area people depend upon the forest materials and agricultural protection. They destroy forest for cultivation and settlement. The dense forest of Terai is being destroyed gradually which brings more probability of depletion of forest in near future. The awareness programme should be conducted to preserve forest. People should also participate in the plantation and conservation programmes.
-
Use of land and its conservation
Agricultural activities are more in Terai region because of fertile land. The farmers use chemical fertilizer for more and better production. The fertility of land of Terai has begun to diminish due of flood, landslide and over encroachment of human activities.
The use of chemical and fertilizer should be minimized, the soil erosion of the hill should be checked and people should be made aware about the land conservation to protect the land of the Terai region.
-
Livestock farming
The livestock farming such as cattle and goat for milk, meat, manure and other purposes have also been done in this region. People take cattle in forest and pasture to graze. The forest and pasture are depleting due to overgrazing.
Animals should not be allowed to graze freely because they destroy the young and valuable plants. Positive attitude towards conservation of ecosystem should be developed to protect the environment.
-
Construction work and conservation
The construction work is rapidly increasing in this region. It disturbs the natural environment. Construction works have also disturbed the lifestyle of wildlife and birds. The road, dam, canal etc. are the construction works that directly affect the ecosystem.
The rational attitude should be developed while conducting the construction works. The construction work should be eco-friendly.
-
Industrial development and pollution control
Terai is rich in raw materials. All types of raw materials required for the industry are available here. Different types of industries like jute industry, sugar industry, paper industry etc are established here. These industries emit smoke, harmful gases, chemical etc. and pollute the environment.
The industries should be managed properly. Wastage and sewage from industries should be treated carefully before discharging to the land and water resources.
Measures to minimize the adverse effects of Modernization
Modernization and developmental activities are the necessity of life. It makes our life easier, more comfortable and safer. Modernization and development without environmental conservation is harmful to us in the long term.
Therefore, the following measures should be considered to minimize the adverse effects of modernization and development:
- While using the natural resources, the ecosystem should not be disturbed.
- We should avoid construction work in such areas where a large number of birds and animals reside.
- While constructing roads, industries, canal and dams, proper environmental conservation programme should be integrated with the construction work.
- There must be proper management of sewage and drainage system.
- There must be provision of dustbin, public toilets in certain public places.
- We should encourage the concept of planned housing project and discourage the random housing practices.
