Issuing a Decree to Ensure the Legal Protection … [Honduras]

Honduran Forest Legislation establishes the strict protection of microbasins from human exploitation. However, in practice, there is an accelerated rate of microbasin degradation brought on by land use changes that turn forest lands into crop lands. Through sensitization, raising awareness, and training aimed at the general population and Water Management …

2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

A series of vegetative, structural and management technologies is used reduce the exposure and vulnerability of water infrastructure to threats. These include protecting water sources and water tanks, the stabilization of their surroundings, the anchoring of piping and, whenever necessary, repairing the water tank.

2.2 Detailed description of the Technology

Description:

The Department of Olancho, located on the nortwestern region of Honduras, is frequently affected by tropical storms and hurricanes coming from the Atlantic. The Impacts of the hydrometereological hazards are intensifed by unsustainable use of natural resources practices that promote rampant forest fires, soil and water degradation and erosion. Rural communities' health is precarious.

"Resiliencia" (Resilience) is a project undertaken by the Honduran/Swiss Red Cross. It intends to provide sustainable contributions to enhance resilience in the rural regions of Olancho by combining the efforts to reduce risks posed by hazards (RHR) and those aimed at promoting health at all levels (home, community, municipality). By improving and ensuring the care of drinking water systems and providing training to manage water, wastewater and health practices, the project looks to establish for synergies between RHR and health. Though the communities already have water facilities, these are frequently old and prone to failure. The project provides communities technical and financial support to repair and improve their water system, starting from the water outlet, the water tank and the piping that extends to houses. Risk reduction is addressed throughout the entire process, Water infrastructure is protected through different measures that are defined through assessment of the state of the water system. The water tanks are improved whenever necessary, i.e. its interiors are repaired with ceramic and coating; further, the outer parts are coated and fissures are repaired. In most cases, the piping has to be changed with more resistant material (PVC is replaced with galvanized iron) to avoid fissures along the conduction line. The valves are repaired and hypochlorinators are installed. Vegetative measures - such as planting trees and shrubbery to stabilize soil and retain water - are implemented around the tanks and water outlets. These plant-based measures around the tank reduce risks of landslides; also, planting trees in the microbasin helps ensuring water provision in the quantities and quality required (for more information, see T 750). Finally, management measures are executed to reduce the risk of pollution. These measures involve, for example, ensuring strict protection of the water outlet and the water tank with a surrounding fence.
Maintenance activities include constant supervision of the pipes and cleaning of the tanks (these are emptied, cleaned with chloride and then refilled) every 8 days (in winter) and every 15 days (in the summer) by the Water Board.

Comments/ specify:

There are less fissures and, thus, less water leaks, since they PVC pipes were replaced with galvanized iron.

drinking water quality

decreased
increased
Comments/ specify:

In the case of Pisijire, water quality treatment does not take place in the water tank but in a purifying plant at the community. Thus, tap water is not apt for human consumption but rather used exclusively for washing/ cleaning/irrigation. However, the monthly water allowance (80 Lempiras = 3.5 USD) includes 90 bottles of drinking water per month per home.

In the future, one water tank will not be enough for the community, since it is growing rapidly. An investment in piping will also be needed.

6.5 Adoption of the Technology

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

500 homes (100% of the community) have access to drinking water

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?

No

6.7 Strengths/ advantages/ opportunities of the Technology

Strengths/ advantages/ opportunities in the land user’s view
Protection of the microbasin ensurea water quantity and quality.
Water is a necessary resource and it motivates people to invest their effort into protecting and maintaining the system. Also, it is easy to fine people who break regulations to ensure the lands belonging to the microbasin are not used, this can deplete water.
Availability of drinking water improves the health of the population. This increases labor and in the long run it will result in development for the community.
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
Improves the comprehensive management of water system and thus improves coordination efforts with CODEL, the Health Committee and the investment plan.

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?
In the future, the water tank will no longer cover the needs of their growing population Expand pipe network build a second tank (opinion of the Board and CODEL)
Set a quota according to water use to avoid waste (opinion of the compiler)
