MoL002:Mapping and GIS database for Adarsha gram
Agricultural Khas Land Distribution to the poor and landless is one of GoB’s important poverty alleviation policies. In Bangladesh, Khas land is government owned land, managed by the Ministry of Land (MoL). Since 1972 the Ministry of Land (at that time called Ministry of Land Administration and Land Reforms) started rehabilitation of landless in the char areas. Under Different names (Adarsha Gram, Asrayon, Abashon) resettlement continues up to today. From May 1990 the European Commission co-financed Adarsha Gram and this financing continued up to December 1997. A second phase of financing of Adarsha Gram by the EC started in October 1999. This financing was last up to October 2006. These periods of financing were referred to as Adarsha Gram-I and Adarsha Gram-II.
The projects’ main objective was to support poverty alleviation of landless and homeless of rural Bangladesh by improving living conditions, education, health and earning opportunities. This was done by resettling homeless and landless households in Adarsha Gram communities on suitable agricultural Khas land and by providing skills, and awareness building training, as well as access to income generating activities with the help of NGOs. In Adarsha Gram-1 27056 households were resettled in 603 communities. In Adarsha Gram–II 22734 households were resettled in 427 communities of which 18 communities were lost due to river erosion (without a loss of lives). The number of lost Adarsha Grams-I was unknown. In Adarsha Gram–II an additional 427 settlements were prepared for construction in a future phase (further referred to as Adarsha Gram–III).
Development of GIS database and mapping of Adarsha Gram location was the crucially important issues of Project Management Unit (PMU) and EC consultant of Adarsha Gram project for future planning activities of Ministry of Land.
Following the above context, On 1 June 2006 the Program Management Unit (PMU) of the Adarsha Gram-II Project signed a contract with the Center for Environmental and Geographical Information Services (CEGIS), a public trust of GoB’s Ministry of Water Resources to produce the GIS database and maps of the location of the Adarsha Grams of phase 1, 2 and 3 and do capacity building of PMU staff with a GIS training.

CDM003:Development of Hazard Zoning Maps using CRA Process
Hazard Zoning Maps were developed under EC funded Component 3d: Support for Livelihood Security – Hazard Awareness component of CDMP. The main objective was to develop Hazard Zoning Maps for all natural events using CRA processes and products in the entire areas of 64 unions and 4 pourashavas under 7 vulnerable upazilas one form each of the 7 pilot districts namely Hatibandha (Lalmonirhat), Godagari (Godagari), Sadarpur (Faridpur), Chouhali (Sirajganj), Assasuni (Assasuni), Dharampasha (Sunamganj), Moheshkhali (Cox’x Bazar). CDMP prepared Community Risk Assessment (CRA) in 7 pilot districts. The hazard information were collected through CRA process by NGOs assigned by CDMP in all 67 unions/ paurashavas. The CRA information was the main input to this assignment which were validated through field visits. The information was used into the GIS system to produce the outputs in the form of high quality GIS dataset reflecting natural hazards in the local contexts. The dataset was enriched by incorporating settlements, roads, water bodies, other important features (hat/bazaar, educational institutes etc) from SOB Topo Maps and FINNMAPs. Hazard and vulnerability analysis was done using GIS techniques. Weights and preferences were applied for developing hazard index. Multi Hazard Zoning Maps are easy, meaningful, scientific, user-friendly, value added output of the CRA process. This would be helpful for the local community, planners, disaster managers and decision makers for disaster management and risk related activities.
In Bangladesh different organizations have different pieces of data that would be useful for planning and responding to disaster management. Many government agencies such as LGED, BARC, IWM, CEGIS, BWDB, SRDI, BBS, and SPARRSO, SOB has GIS setups and are maintaining valuable spatial databases which are being developed progressively over the years. Unfortunately, those data (both GIS and tabular) are not compatible among the organizations. In case of GIS data, the incompatibility mainly arises due to the differences in projection system, Datum and Parameter. Organizations are using the LCC or UTM or BTM projection system with. This is happening mainly because of the absence of policy direction, absence of data standard, lack of co-ordination among the organizations, choice of foreign and local experts etc. The extent and standard of the metadata have not yet been determined in Bangladesh at National Level. Therefore, in order to make the GIS data compatible among the data generation and data user agencies and to determine the standard of metadata, a national GIS and metadata policy and as well as data sharing protocol is required to develop. This project is targeted to address these issues. The implementation of GIS policy will bring the GIS data from a heterogeneous to homogenous format. This will help the users in obtaining data with good precision and timely access employing the minimum resources.
CDM005:Inventory and cataloging of geological data sources, types and availability
Geological data is very important to analyze the hazards and planning of disaster management. But no central data repository or catalog yet exists in Bangladesh. These data are available in many government and non-government organizations. Such as SOB (Survey of Bangladesh) contains topography, land administration, aerial photograph, satellite images; BWDB contains topography (1:50,000, 4 inch=1 mile) and irrigation map (1:40,000); BIWTA contains Finnmap (1:50,000); LGED contains Thana map; GSB contains Geological map, reports, articles on geological information of Bangladesh; many non government organization has sub-soil profile data. These data are stored in hardcopies and in digital forms; many of these are only available in hardcopies. The historic geological data which have not yet been digitally archived are vulnerable to be lost or damaged. Those data are highly valuable; e.g. old topographic maps of 1960s having detail contour information are extremely required and valuable for trend analyses to investigate the anthropogenic modifications of the urban ground. These data can also provide valuable information to investigate the landscape dynamics and associated hazards and their severity. So, it is urgent to collect these old maps and to digitize the information there on for proper preservation in useful format. Another example is sub-surface soil profile data; these data reflect the engineering aspects of the sub-soil. Soil-liquefaction and land-subsidence studies can be undertaken using those data. Hence, it is necessary to archive those data in digital format and a central data catalog is highly necessary to facilitate different geo-hazard assessment for planning of disaster management and other necessary actions.
