Wetland Preservation in Dhaka City Area

Bangladesh is a Tropical monsoon country of South Asia with geographical location 20°34’N to 26°38’N and 88°01’E to 92°41’ E bordering the Bay of Bengal in the south with a coast line 734 km, Myanmar for 193 km in the south east and India for 4,053 km in the west, north and east. It is a part of humid tropics, with the Himalayas in the north and the funnel shaped coast touching the Bay of Bengal in the south. The country comprises of an area of 147,570 km² with a population 165 million. The terrain is mostly flat; hilly in southeast. Natural hazards include droughts, cyclones; much of the country routinely flooded during the summer monsoon season. Many people are being forced to live on flood-prone land with limited access to potable water. Water-borne diseases are prevalent. Water pollution is a big problem as a result of commercial uses of pesticides. In addition, there are intermittent water shortages, soil degradation, deforestation, and severe overpopulation.

International Year of Biodiversity

World Environment Day was observed in a befitting manner. The day was declared as the International Year of Biodiversity with the theme “Many Species One Planet, One Future”. Dr Mahammed Ataur Rahman, Director, Centre for Global Environmental Culture of International University of Business Agriculture and Technology (IUBAT), Uttara, Dhaka has strongly advocated for the importance of biodiversity saying as “The more species provide better scope for adaptation, survivability and food security in the changing climatic condition. He emphasized the needs for protection of species and varieties within the species which are developed after hundreds and thousands years of adaptation. Continue reading

Revolution of Jhumia’s life through Rubber plantation: A Case Study of Dhalai District, Tripura

Author: Sukanta Sarkar, Lecturer in Economics, ICFAI University, Agartala, Tripura, India, E-mail: Sukantaeco@gmail.com
June 6, 2010

ABSTRACT:

Jhum cultivation is a form of agriculture in which the cultivated or cropped area isshifted regularly to allow soil properties to recover under conditions of natural successive stages of re-growth. There exists a great deal of direct and indirect employment potential associated with rubber plantation. Economic conditions of jhumia people are very poor and therefore they are unable to purchase those products which are essential for their daily life. Without perceptible improvement in their socio-economic condition, tribal development itself will be at stake. Disparate living standard, differential access to income earning capacity and other amenities are likely to generate discontent among jhumia’s and weaken their motivation to participation in socio-cultural activities. Case study in Dhalai district in Tripura shows that rubber plantation has able to change the economic life of jhumia’s.

Coconut- A Great Plantation Crop for Climate Change Adaptation

“Coconut is an excellent tree crop for Climate Change Adaptation – should be brought under massive cultivation across the country especially in the high water-table zones and in the cyclone prone coastal regions as it can easily reduce the wind speed of storm and mitigate global warming” said Dr Mohammed Ataur Rahman, a re-known Plantation Crop Specialist.

Coconut water is a wonderful safest natural drink, thrust quencher and remedy for diarrhea and cholera. The trees are suitable for climate change adaptation by keeping water table up, controlling erosion, acting as strong windbreaks and reducing storms and cyclones. It rejuvenates and creates soil and it has endless uses. More interestingly, it grows luxuriantly in salinity prone areas without application of chemical fertilizers and pesticides and it is absolutely grown organically.

Bamboo- An Excellent Plantation Crop for Climate Change Adaptation

“Bamboo is an excellent crop for Climate Change Adaptation – should be brought under massive cultivation across the country as it can easily mitigate global warming” said Dr Mohammed Ataur Rahman, a famous Plantation Crop Specialist.

He claimed that bamboo is a very fast growing wonderful natural resource suitable for climate change adaptation by converting atmospheric CO2 into biomass, keeping water table up, controlling erosion, acting as strong windbreaks and reducing storms and cyclones. It rejuvenates and creates soil and it has endless uses. More interestingly, it grows luxuriantly without application of chemical fertilizers and pesticides and it is absolutely grows organically.

“Although it is a great crop with many contributions but a very little study on its production, yield, habit and habitat has practically been done here in Bangladesh” Dr Rahman, an accomplished agricultural researcher thus expressed his great concern during the presentation of keynote paper on “Environment and Cultural Practices of Bamboo” .

Climate Change Adaptation for Cities

Climate Change and Extreme Cyclones

Abstract

Cities are the colonized places of high-dense population, where the inhabitants enjoy easy livelihood, communication, healthcare, education, security and recreation facilities. Due to climate change effects, the basic ingredients namely air, space, light, water and other logistic support and services of a citizen are increasingly hampered and the cities are becoming inhabitable. The present study analyzes the magnitude of climate change effects on city lives and works out the ways of adaptation to reduce the risk of the anticipated disasters. It is found that migration towards the cities for livelihood is increasing at a very high rate and the cities are increasingly facing various crises like accommodation, energy, transportation, pollution, wastes, insecurity, crimes and social unrest. Resource management and biomass recycling have been seriously affected. It has also been investigated that the poor planning and administrative weakness aggravate the crises. However, it has been found that the cities are the ultimate shelters during major disasters like floods, tidal surge, cyclones, tornadoes and famine. To keep the cities safe and habitable, the ways for mitigation of climate change effects are focused, and appropriate ways are recommended for better adaptations. Continue reading

Palmyra Palm: Symbol for Sustainability

Palmyra Palm is proposed as the Symbol for Sustainability

Palmyra palm is cosmopolitan, grows in versatile environmental conditions viz. Ethiopian desert to Cox’s Bazaar Sea Beach of Bangladesh and high rainfall areas of Indochina; from Uzbekistan to South Africa. It adapts high plateau, hills and flats and low-lying lands, High humidity to droughty conditions. It can withstand wind speed of 300 miles/hour and it is the best windbreak against the storms. prescription drugs without It gives fruits, toddy, fibers, claddings and timber; controls soil erosion, allows undergrowths and a good shelter for weaving birds. Palmyra palm has many medicinal values especially to rejuvenate the olds.

Food Security and Soil Fertility of Hilly Areas of Bangladesh

  1. Relevance of the Action

Bangladesh occupies an area of 144,863 km². The hilly areas cover about 17,342.km² mostly in the Chittagong Hill Tracts districts, Chittagong, Habigonj and Moulavibazar. Hills constitute about 12 per cent of the total area of Bangladesh. Chittagong Hill Tracts districts alone covers 13,184 km² which is about 9%.Based on geology and landform, the hills of Bangladesh may broadly be subdivided as:  1. High hill ranges (about 70%) and                              2. Low hill areas (about 30%).   The high hill ranges, about 200-1,000 m above mean sea level (msl),  are steep to very steep hills and usually have a rather youthful soil mantle ranging from a few cm to several metres in thickness over bedrocks. In contrast, the low hill areas, about 15-200 m above msl are nearly flat or rounded topped and usually have old and deep soil. The whole hilly region receives more than 2000 mm precipitation annually about 80% of which receives in 4 months (June-September) and the region was covered by tropical climax forest with diversified flora and fauna just a century back. Due to human pressure, the deep forests were deforested to denuded hills. Moreover, introduction of tillage cultivation practices and uses of chemicals a good number of indigenous flora and fauna have lost their habitats. Continue reading
