Food Security and Soil Fertility of Hilly Areas of Bangladesh

September 15th, 2009
  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. Read the rest of this entry »

Study on the Traditional Practices for Solid Waste Recycling in Rural Homes

July 14th, 2009

Study on the Traditional Practices for Solid Waste Recycling in Rural Homes Mohammed Ataur Rahman, PhD           CoordinatorCentre for Global Environmental Culture (CGEC)              IUBAT—International University of Business Agriculture and      Technology  4 Embankment Drive Road, Sector No. 10, Uttara Model Town, Dhaka-1230, Bangladesh  E-mail: ar_forest@yahoo.com   Website: www.iubat.edu  ABSTRACT Solid wastes are important components for recycling biomass to return the nutrients to their origin. Traditionally, the people of the Ganges and the Brahmaputra basins have been recycling solid wastes for centuries. The practices which are followed here have scientific merit but in most of the cases, the people are ignorant about those facts. The present study was conducted in 90 rural homes of Ishwarganj and Nandail Upazillas under the district of Mymensingh. The objectives of the work were to find out the scientific explanations of the recycling how to get prescription drugs without a prescription practices. The study showed that the traditional procedures which are being applied on trial-and-error basis got the effective result of supplementing organic materials to the soil. Although these effective practices have been used generation after generation, in-depth studies were not carried out. This study has uncovered the scientific reasons behind many of the traditional practices of solid waste management. Chemical analyses revealed that most of the macro-nutrients, namely potassium, phosphorus, nitrogen, calcium, sulphur, magnesium, iron and total organic matter contents were not depleted; rather, the total organic matter contents increased significantly after the recycling. This kind of rural home-based and short-cycled solid waste management ensures zero depletion of organic soil content.

A Few Proposals for Sustainable Agriculture and Development

October 22nd, 2007

The present world’s agriculture is passing a very crucial time. With the advancement of high technology, a rapid development has been made to meet the immediate demand of food and many day-to-day essentials for growing the population of the world. However, this quick advancement seldom considered long term effect of the earth’s environment. Industrialization, improvement of crop, use of chemical fertilizers and pesticides and mechanization of cropping culture has brought rapid changes and has imbalanced/disturbed the spontaneous ecosystems. It is true that cropping/farming is a biased culture which solely depends on the desire of the human being. Moreover, multiple needs have made it commercial i.e. market product for profit/benefit. Obviously market commodities always seek immediate result i.e. more profit. To ensure more earnings, agriculture has become more selective and mechanized and more external input based for which we have lost diversity among and within the species.

Management of Tea and its Associated Forest Crops for Sustainable Environmental Development and Tea Production in Bangladesh

March 27th, 2007

ABSTRACT

Since 1995, an elaborate study was conducted on tea plantations of Bangladesh to evaluate the status of tea production. An effort was made to analyze the reasons for low yield and productivity and to find out easy and sustainable practices to improve the yield and production, to meet the growing demand of tea, considering the habit and habitat of tea plants. Importance of tea was studied from the historical past, present consumption trend and prevailing price and its future forecast on its popularity as a safe natural leaf beverage in the health conscious world.

Problems of Rubber Production in Bangladesh and Their Solutions

October 11th, 2006

Jat/Clones, Cultural Practices and Processing

Introduction

Rubber is one of the most important cash crops, with multipurpose uses. It is produced from the latex of rubber trees (Hevea brasiliensis (Willd. ex Adr. De Juss.) Muell. Arg.), an exotic deciduous rain forest tree species of Family Euphorbiaceae. The British planters first introduced it in Bangladesh in the early twentieth century. But commercial plantation was started in 1961 by the government in Chittagong and Sylhet hilly regions. Later on, plantations were expanded in Chittagong Hill Tracts and Madhupur by the government and public enterprises. The British and some other private companies also planted rubber in the fellow lands of tea estates. At present about 25,000 hectare of land is under rubber plantation in Bangladesh, and annual production is about 7,500 tons against 20,000 tons country’s total demand of natural rubber (NR). Although production of NR is far less than the demand still the price is very low, even less than the cost of production, due to competitive low price of NR and synthetic rubber (SR), a bi-product of crude oil, in the international market.

Study on Some Indigenous Under-utilized Spices of Bangladesh

September 13th, 2005

Introduction

Spicy food is the tradition of Indian Civilization from the time immemorial. Flavoring food and making it tasty by adding different plant parts during cooking or making paste or salad is a very common practice everywhere. Spices are the symbol for aristocracy, health, tonic, immunity, vigor and stimuli. A Bangladeshi cannot think a meal without use of spice.

Underneath the taste and flavor the spices posses immense nutritional and medicinal value which is proved by the today’s scientists. The Arabians and the western traders realized the value of Indian spices and trading began thousand years back. Global trade in spices is expected to attain higher levels due to anticipated advances in the global food industry, and is posed for a major leap in the 21st century (Singh, 2002).

Crop and Environment

January 11th, 2004


Introduction

Crops play a very significant rule in changing environment. Crop is the man made culture involving biological and non-biological activities. Probably it is the product of human’s first biased act on the virgin earth. Crop is the man’s day-to-day needs obtaining from limited source, utilizing merit, labor and natural resources to ensure the continuous supply regenerating as per choice and requirement. It may be for their direct, indirect, primary, secondary and tertiary purposes, e.g. food, fodder, cash crop, medicinal, fiber, forest, agriculture, horticulture, aquatic and marine crops etc.

January 11th, 2004

Need for a home

From the very beginning of civilization man felt his need for food and shelter and thus made home for living in and around the easily available place for food and other primary requirements of life. As a colonized and socially behaved human being they gradually put off their nomadic habit and established permanent place for living, the home.

Basic criteria for a home: They considered the following criteria for their habitat:

  1. Food
  2. Water
  3. Safety
  4. Building materials
  5. Easy movement
  6. Protection from adverse conditions
