Abstract/ Executive Summary:

The study was conducted during 2003-2004 for documentation and mapping of chilli growing areas in Bangladesh by Geographic Information System (GIS) technology. Data for the present study were collected from Statistical Yearbooks of Bangladesh and Department of Agriculture Extension (DAE). From the figures and maps, it was found that the area (63%) and production (28%) of chilli occupied the major share of spices crops in Bangladesh. The growth rate of area, production and yield of chilli was 97%, 98.60% and 4.26%, respectively during the period of 1995- 2001. The Chittagang division was found in first position for area (175 thousand ha) and production (153 thousand ton) of chilli followed by Dhaka and Rajshahi division and lowest was Sylhet for both area and production. But in case of yield, Sylhet and Rangpur area was in top position (1.34 1.36 ton/ha) and Pathuakhali stands lowest position (0.59 ton/ha) Its area and production expansion should be intensified in the farmer's fields and yields he increased equally in all locations.

Start Date: 00-00-2003

End Date: 00-00-2004

Program Area: Knowledge Management

Commodity: Chilli, ICT

Objectives:

To study can provide information for the policy makers, donors, researchers and extension people in Bangladesh through GIS.

Methodology:

The information furnished In this paper is primarily based on secondary data. Primary data and information were collected from DAE personnel through informal interviews. Secondary data were also collected from different BBS (1995-2001), proceedings and official documents. Data were entered in the computer by using the programs such as MS-Excel, Fox-pro, MS-access. The boundary of the data was taken for last six years. GIS Center of BARl was used for mapping and documentation. District boundary map was digitized by using Arc-Info program. The administrative boundaries of 21 districts were used for mapping of spices. Data were converted into standard units (ha. tons). Data were classified into some classes on the basis of particular cultivated area of different spices crops. The area under each class (frequency) belonging to each district was identified by tally marks. The growth rate calculation was done with the help of ordinary least square (OLS) method used by Excel and SPSS program. Other package programs such as MS-word, Power point were also used for the purpose.

Achievement/Findings:

The analysis indicated that prospect of chilli cultivation in Bangladesh has very bright future. The growth rate of area and production of chilli was found very high and significantly positive. The growth rate of yield was not satisfactory. So, there should have a greater scope of increasing production with introduction of modern variety and production technology. The visualization of maps and graphs of chilli was found very effective for easy understanding of spices situation and helps for future planning of the spices. Emphasis has to be given on technological advancement. varietal research and strengthening extension services.
