Abstract/ Executive Summary:

Bangladesh is a least developed South Asian country and its economy is based on agriculture. Among the natural resources, land and soil are the key resource for agriculture. We have to ensure its proper utilization for ensuring food security without decreasing its extent and quality. In Bangladesh the natural resources especially the land resources of an area is used for multiple purposes, which have strong influences on the socio-economic development of the area. Due to huge population pressure land resources are under continuous human and natural interventions so its land use is naturally diverse and complex. The land resources of an area is intensively used for agriculture, settlements, forests, water bodies and fisheries, salt production, industries and infra-structural development, tourism, preservation and management of environmentally important and special areas. Land and soil resources are vital and limiting resource for agriculture. The encroachment on agricultural land is a pressing problem in the rapidly growing areas of our country. Cultivable land has reduced from 9.72 million hectare (1991) to 8.52 hectares (2011). This is alarming for an over populated country like Bangladesh. Food security of the country would be threatened if land and soil resources are degraded and cultivated area is reduced at present rate. To arrest negative balance land zoning is a must for sustainable agricultural development of the country. Secondary data were obtained from publications of Soil Resource Development Institute (SRDI) and Department of Land Records (DLR). They provided spatial information pertinent to land zoning in Kaliganj Upazila. All maps were constructed in ARC/Info and exported into shape file formats compatible with ArcView 3.2. All themes were projected in the LCC having a scale of 1:50,000. Current land use data were collected by field survey which provided an opportunity to develop a working relationship with land use, topography and landscape characteristics. The ultimate output of this study was a map showing the distributions of the various land zones. The Kaliganj Upazila comprises of about 21,316 ha land surface. Agriculture zone, Forest zone and Aquaculture zone accounts for 5,247ha, 8,760 ha and 5,871 ha respectively. About 858 ha area accounts for Commercial and Residential Zone and about 583 ha for Water bodies including rivers. The proposed urban zone accounts for 715 ha.

Keywords: Bangladesh; Soil and land resource; Land zoning

Location: Palash, Gazipur district & Chokoria, Cox'sbazar district

Start Date:

End Date:

Program Area: Resource Development and Management

Commodity: Land management

Objectives:

a. To ensure planning of proper utilization of land and soil potentials of particular area in order to maximum economic return.
b. To maintain bio-diversity in the area.
c. To grow awareness amongst planners, users, policy, makers and decision makers for rational utilization of land resources.

Methodology:

Study was done by remote sensing and GIS technique of data acquisition, retrieval and analysis. Upazila nirdeshika data base was used as secondary data. Data were analyzed and land zoning was accomplished for proposing best uses of available land and soil resources.

Achievement/Findings:

Bangladesh is principally an agricultural country, characterized by rice paddy agriculture dominated landscapes. Land resources are the major asset contributing to wealth and livelihood in rural areas. It is evident that all the identified phenomena or threats to the human race are narrowly related to land. We all need land to live on, to build our shelters on and to extract our food from. Land cannot always be treated like any other commodity it is very significant and thus valuable. In addition to its pure economic value, it often has serious social and religious implications. Because of present problems of over utilization of land resources, pollution and scarcity of land (also in developed countries), the idea that we should hold the land as stewards for generations to come is frequently expressed. Within this framework of ideas, a balance between exploitation/utilization and conservation of land resources must be found in order to obtain the sustainable development indicated by the Brundtland report. As an agro-based country, Bangladesh has little scope of degrading land resources through improper use. Rational use of soil and land resources is vital for sustainable agricultural productivity and food security. Land zoning is a scientific tool to classify soil and land resources according to their potential use. Hence, land zoning is urgent for a small country like Bangladesh.
