2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

Emergency infrastructure including shelter and linked transport infrastructure, consists in establishing specific flood shelters (for people and animals) including flood-proof collective water sources and communication infrastructure as well as health and school facilities that may serve at the same time as emergency shelters during floods.

2.2 Detailed description of the Technology


The technology applies to the specific context of the ‘Char’ land in Bangladesh, characterised as riverine sandy Islands along the Jamuna River. More than 80% of the land in the intervention area can be classified as 'Char' and is inhabited by 60% of the population served by the project. Every year, especially during floods, the rivers deposit huge amount of silt sediment that makes the land fertile. At the same time, river action washes away some portion of the 'Char' which at times can be quite large and has a strong impact on people's lives and livelihoods. Before the intervention, people living on 'Char' land depended on their traditional early warning mechanisms and were frequently surprised by floods that destroyed their crops and put their lives in danger. Due to recurring floods, people didn’t have the means to improve their built environment. The 'Char' land is furthermore characterised by its lack of public infrastructure and remoteness to public services.

The technology consists of setting up an emergency infrastructure and ensuring community access to these infrastructures during times of floods. It has to be understood in close interrelation with the approach of setting up an early warning system. The emergency infrastructure includes specific flood shelters (for people and animals), flood-proof collective water sources and sanitation systems, transport infrastructure such as foot bridges and elevated rural roads, as well as flood-proof health and school facilities that also serve as emergency shelters during floods. The flood shelters are built on a raised bed of soil and located at sites selected by the communities that are relatively better protected from flood and river erosion within the 'Chars'. The purpose of the technology is to ensure safety of life and protection of assets during times of emergency and also to mitigate sufferings related to floods. The flood shelter is an elevated plane land which is on an average 220 square feet by size and at least five feet high from the existing ground level. The site is selected by the community and should be connected through an elevated road to the nearest community. This arrangement helps people to get easy access during times of floods. The shelter has collective hygienic latrine facilities and safe water sources. People generally dismantle their housing while evacuating and reinstall it on the flood shelter.
The major activities include facilitating the development of community-led risk reduction action plans and their implementation through community participation and engagement of local governance institutions. This includes maintenance of the built infrastructure as the joint responsibility of the community and the local government. Land use, especially sowing and harvesting, is increasingly linked to flood related forecasting measures which has led to significant adaptation in the timing of farming activities. This coupled with the creation and access to emergency infrastructure allows for a relatively safe and healthy living. The adopted technology and approach has led to adapted livelihoods, reduced health costs and increased income. The technology has furthermore led to mainstreaming disaster risk management in policies and approach of local government institutions. Increasingly the local government’s cash and food for work programmes are targeting establishment and/or reinforcement of emergency infrastructure that can cater to larger population. Increased investments are made especially towards flood shelters and improving communication and access to emergency infrastructure. Since the technology is based on local knowledge and has been developed in consultation with the involved communities, it is generally well accepted with a fair degree of ownership and involvement. However, parts of the region are also prone to river erosion and this has a destructive impact on built infrastructures. The technology does not assure any safeguard against this form of uncertain river action.

Total costs for establishment of the Technology 2502756.3
Total costs for establishment of the Technology in USD 31680.46
If land user bore less than 100% of costs, indicate who covered the remaining costs:

10% of all construction cost (except community resource center) is borne by the user. Another 15% is provided by the local government bodies. The remaining 75% is subsidised by the project.


Defining costs of establishment is bit tricky as the measures differ in size and number, costs vary from one village to another depending on the geographical location. However, average costs of the measures further to those highligted in the table are given below:
Disaster resilient tube well: labour (mason) 3'000, equipment (drilling charge) 1800, construction material (bricks, cement, sand, iron rod, PVC pipe, cylinder, GI pipe, tubewell head) 23'250, transportation 2'650, total unit costs (BDT) 30'700
Concrete platform for (existing) tube well : labour (mason) 600, construction material (bricks, cement, sand) 2'450, other (Transportation, waste water disposal) 1650, total unit costs (BDT) 4'700
Wooden bridge: labour (mason, mason assitant, painting assistant, earthwork) 30'000, plant material (grass plantation) 12'500, equipment (painting brush etc.) 1'000, construction material (timber, nails, tar, tarpin oil, paint) 260'000, Transportation 30'000, total unit costs (BDT) 333'500
Road construction/repair: labour (earthwork) 102'500, plant material (grass plantation/turfing), 12'500, total unit costs (BDT) 115'000

4.5 Maintenance/ recurrent activities

Activity Timing/ frequency
1. Construction of Flood Shelter During dry season
2. Raising school compound During dry season
3. Construction of Community Resource Center (CRC) During dry season
4. Installation of disaster resilient tube well During dry season
5. Construction of concrete platform ror (existing) tube well During dry season
6. Construction of wooden bridge During dry season
7. Road construction above flood level During dry season

Due to the softness of the sandy soil and the annual inundation, every measure requires considerable maintenance. The flooding generally washes out sands and decays the foundation of the structure. If maintenance is done in regular intervals, the entire structure remains functional. Also, grass needs to be frequently replanted as it dries up during the dry season.
The users and the local government (Union Disaster Management Committee) are mainly responsible for maintenance of all built assets and structures including the Community Resource Center. The relevant operation/repair and maintenance training has been provided by the project.. Maintenance manuals and guidelines have been developed and disseminated. Also, repair and maintenance equipment has been provided to cadre of users/caretakers trained in repair/maintenance work.

4.6 Costs and inputs needed for maintenance/ recurrent activities (per year)

Construction material Tape etc. lumpsum 1.0 250.0 250.0 10.0
Total costs for maintenance of the Technology 12570.0
Total costs for maintenance of the Technology in USD 159.11
If land user bore less than 100% of costs, indicate who covered the remaining costs:

Maintenance costs are to date (2017) distributed as construction (10% by the users, 15% by the local government). A cost transfer scheme to the users and local government for maintenance is developped to be applied in the follow-up phase.


Again, defining costs of maintenance is also not easy as the measures differ in size and number. Average costs of the measures, further to those for flood shelter including disaster resilient tube well as highligted in the table, are given below:
Raised school compound: labour (earth work and sand bag filling) 7'800, plant material (grass plantation) 1'000, construction material (plastic bag, rope) 500, total unit maintenance costs (BDT) 9'300
Community resource Center (CRC): labour 1'200, plant material (grass plantation, seedlings) 10'500, Transportation 1'000, total unit maintenance costs (BDT) 12'700
Concrete platform for (existing) tube well : labour (mason) 500, construction material (bricks, cement, sand) 600, total unit maintenance costs (BDT) 1'100
Wooden bridge: labour (earthwork) 2'500, plant material (grass plantation) 3'000, construction material (plastic bag, rope) 2'000, total unit maintenance costs (BDT) 7'500
Road construction/repair: labour (earthwork) 10'000, plant material (grass plantation/turfing), 1'500, construction material (plastic bag, rope) 500, total unit maintenance costs (BDT) 12'000

4.7 Most important factors affecting the costs

Describe the most determinate factors affecting the costs:

Transportation of raw material from the mainland to the sites on the 'Char' Islands varies across seasons. In the dry season it is much higher compared to monsoon as the delivery of material is easier in the latter due to extended river outreach.

Short-term returns:


Long-term returns:

slightly positive


The limited returns that have been generated by the project is highly valued by the users from a cost - benefit perspective; especially when they understand that the project is not directly linked to land management practices. Thus, the indirect benefits are perceived to have high value.

6.5 Adoption of the Technology

  • > 50%
If available, quantify (no. of households and/ or area covered):

Out of a total of 8828 HHs targeted by the project, around five thousand HHs in three union have benefitted from the implementation of the technology.

Of all those who have adopted the Technology, how many did so spontaneously, i.e. without receiving any material incentives/ payments?
  • 0-10%

6.6 Adaptation

Has the Technology been modified recently to adapt to changing conditions?


If yes, indicate to which changing conditions it was adapted:
  • labour availability (e.g. due to migration)
Specify adaptation of the Technology (design, material/ species, etc.):

Dredging machine has been used for building some emergency infrastructure at few sites due to unavailability of labour at the time of construction.

6.7 Strengths/ advantages/ opportunities of the Technology

Strengths/ advantages/ opportunities in the land user’s view
Emergency structures are collectively owned and have a multipurpose use; in 'normal' (non-emergency) times they are used for other purpose than safety and protection which includes community meeting, workshop and training
Expanded opportunities of communication during flood
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
Community is aware and driven to implement flood preparedness and risk reduction measures on its own
Appropriate measures can significantly change people's mindset and behaviour

6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them

Weaknesses/ disadvantages/ risks in the land user’s view How can they be overcome?
River erosion threatens built structures Careful site selection for construction work through in depth discussion with community people supported by scientific analysis
High investment needed for building physical structures (e.g. CRC building) in the char which the local government and community find difficult to finance without external support. Install portable semi-permanent structures in the char; Lobby for greater decentralisation of finances to local government
