Govt doing dev works at the cost of environment: Experts
Environment experts have said the government has adopted a significant number of development works for economic growth at the cost of country's environment.
Such trend is currently posing serious threat to the total eco system of the country, they said while talking to the Daily Observer on Monday.
To ensure sustainability of the environment and the earth the pattern of the development should be changed and it is possible if a country follows Nature based Solutions for Development.
Eminent climate expert Dr. Saleemul Huq, Director, International Centre for Climate Change and Development (ICCCAD), said every country needs to find nature-based solutions in each and every ecosystem.
He also noted that each member of the least developed countries should find its own adaptive measures to combat the impact of climate change.
"The Least Developed Countries must set up their own adaptive measures and gain resilience capacity to decrease the impact of climate change based on their own reality and experiences," he made this comment while talking to this correspondent.
From the previous development work activities many environment experts have noted that the introduction of eucalyptus trees was harmful for the eco system of Bangladesh.
Similarly using excessive pesticides and chemicals has killed insects, makes lands barren, drives away fishes and destroys trees. Even grass, a fodder, turns poisonous to domestic animals.
Pesticides have proved to be more harmful than pests as those destroy the nutrition sources which finally disrupt the food chain especially in the coastal area of Bangladesh.
Soil scientists said continuous use of chemical fertilizers and pesticides in the arable land gradually decreases its productivity.
Chemical fertilizers also destroy the soil bio mass, which is important for maintaining ecosystem and crop production. Excessive use of chemicals destroys soil nutrients like sodium, potassium, nitrogen and creates imbalances in soil fertility, according to researches.
Earlier farmers used various kinds of traditional fertilizers including green manure, cow dung and other organic substances. Paval Partha, a researcher of ecology-biodiversity and conservation, said chemicals and pesticide destroy soil's moisture and gradually turn soil infertile.
Talking to the Daily Observer Paval Partha, a researcher of ecology -biodiversity and conservation, said soil has a food cycle, there is lichen moss, fungus (fungi), bacteria and some micro organisms coexist in the soil and they depend on each other.
"Snakes, frogs, earth worm, snail, some birds depend on each other; they all are the members of this soil food cycle. The cycle is absent because of use of chemical fertilizers," he said.
"The government must adopt a clear, specific and holistic development works that will not give only economic development but also should protect country's eco system," he added.
Ainun Nishat, eminent water expert, said excessive use of pesticides and chemicals were used only for a specific planted crop ignoring plants like kalmi, pat (jute), shapla (water lily), vegetables and fish which are important sources of food and nutrition for the poor people in the rural areas.
" Now local people faces serious food security because of this development works, before introducing such development works government should have thought about the welfare of the trees and aquatic species, which play a vital role on ecological balance," he said.
We must remember that development works should be holistic considering every part of the nature, he added.
However, when asked Sultana Afroz, Additional Secretary, Ministry of Finance, said the government's commitment is reflected from its policy level decisions to local level interventions to address the adverse impacts of climate change.
