2.1 技术简介

技术定义:

The protection of water resources is essential for the supply of drinking water in the rural zones of Haiti, by enabling to preserve the water quality and facilitate the recharge of the resource. Organizing the actors related to the water resource and to the economic, environmental and communal challenges is crucial. This implies, apart from management, the implementation of various technical measures.

2.2 技术的详细说明

说明:

The majority of water resources in Haiti is subject to bacterial contamination, which endangers the health of the consumers. The infrastructure for the abstraction and conveyance of water is periodically put to the test by the large variation of discharge, like floods, but also by low flows. The protection of water resources aims to strengthen local actors to better manage water resources. The objective is to take care of the protection of water resources at local level according to rules which are established and accepted by the actors with regard to legal, sociocultural and biophysical aspects.

The protection of water resources also implies that technical measures are implemented to conserve and protect catchments, in order to ensure the quality and quantity of the required water and the recharge of groundwater bodies. The technical measures are defined for different zones. Three categories of zones are established with specific restrictions and recommendations, and formalized in a municipal decree which is published by the town councils. A first zone of 1000 m2 directly upstream of the water resource is brought into the domain of the state, fenced, reforested and totally protected from human activities.
In a second zone of a minimum of 5 ha upstream of the resource, restrictions to the use of the terrain apply, notably with regard to defecation, free-range livestock farming and other harmful human activities, in order to protect the soil and the water quality. The terrain is managed so as to guarantee a good conservation of the soils by reforestation (agroforestry) with different varieties of fruit trees and timber. A third zone can be established if supported by the community, with restrictions on slash-and-burn and free-range grazing, as well as means to preserve the soils and to manage the vegetation cover. This latter zone can cover the whole catchment, and is meant to promote groundwater recharge. The restoration of the catchment through the zoning and the implementation of physical structures includes different techniques such as vegetative barriers and stone walls.

The restrictions on the use of zone 2 are not necessarily in contrast with the interests of the producers. It turns out that the rainfed crops are too much exposed to climatic hazards, and that forestry is a more reliable alternative. Therefore they perceive the development and reforestation of their land as an exploitation of their heritage, and as a profitable investment in the long term, when they will be able to manage the exploitation of the trees and their fruit production. In the first two years, a total maximum grant of 400 USD per ha is paid to the producers in different terms, depending on the success of the conservation activities. These experiences have inspired the setting of national standards on the protection of drinking water resources.

4.7 影响成本的最重要因素

描述影响成本的最决定性因素:

The maintenance operations depend on the meteorological conditions (in particular heavy rainfall) and on the type and quantity of structural measures. The topography and geomorphology influence the stability of the structures and hence the maintenance. The maintenance costs are carried by the farmers, or in certain cases by the committee for the provision of drinking water. The control on the restrictions of use of the protected zones is carried out by the local authorities together with the committee for the provision of drinking water. Hence, the costs are distributed over the community funds and financial resources from the water services.

6.7 该技术的优点/长处/机会

土地使用者眼中的长处/优势/机会
The farmers are supported to implement a cost-effective forestry system to replace a very vulnerable rainfed agricultural production system. But it is the population in the downstream part of the catchment who benefits from the protection of the sources, since the quality and quantity of the water is improving. Therefore an equilibrium must be found between the two populations, in order to make both benefit. The water services can be profitable, and hence encourage participation in the efforts of protection upstream in the catchment, by supporting the producers and/or by financing jobs for the protection of land and water.
The protection of water resources increases the value of the common heritage and therefore calls for a community-based management.

编制者或其他关键资源人员认为的长处/优势/机会

On the basis of the vulnerability of the population and the environment in the rural environment of Haiti, the protection of water resources should be established to guarantee a secure and profitable use of water. The participatory methods implemented allow to create a supportive environment, suitable for a community-based effort for local rural development. These mechanisms inspire a culture of citizenship in a local democratic context under development.

6.8 技术的弱点/缺点/风险及其克服方法

土地使用者认为的弱点/缺点/风险	如何克服它们？
The management of state land in zone 1 poses a challenge because this land has to be integrated into the property of the state. The purchase or compensation of these lots can require a long negotiation between the local authorities and the owners.	It is important that the local actors resolve these matters among themselves, and that there is no interference from a project, in order to not distort the negotiation.

编制者或其他关键资源人员认为的弱点/缺点/风险	如何克服它们？
The sustainability of the measures and the cost of maintenance are largely dependent on the quality of the measures.	Ensure a good technical instruction and follow-up on-site by trained staff.
