1.5 Referencia al (los) Cuestionario(s) de Enfoques MST

2.1 Breve descripción de la Tecnología

Definición de la Tecnología:

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 Descripción detallada de la Tecnología

Descripción:

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.

7.	Road construction above flood level	Estructurales	During dry season

Comentarios:

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.

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

4.8 Factores más determinantes que afectan los costos:

Describa los factores más determinantes que afectan los costos:

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.

Land ownership is quite complex as Chars by nature are unstable habitats. In principle land is owned by state but in most cases the politician - musclemen nexus exercises real control. This results in leasing and renting of land which is the predominant form of land ownership in Chars.
