1.5 参考关于SLM方法（使用WOCAT记录的SLM方法）的调查问卷

2.1 技术简介

技术定义:

The ‘couloirs de passage’ are formally defined passageways which channel the movements of livestock herds in the agro-pastoral zones of Niger, by linking pastures, water points and coralling areas, be it within village areas (internal couloirs) or on open land (external couloirs).

2.2 技术的详细说明

说明:

The main goal of the couloirs is the prevention of conflict between agriculturalists and pastoralists regarding the use of limited land and water resources. These conflicts are often provoked by cattle entering cropping areas. The establishment of demarcated passageways allows the livestock to access water points and pastures without causing damage to cropland. The corridors are regulated through the ‘code rural’ – a national law defining the land use rights of the pastoralists. Demarcation of couloirs is based on a consensual decision of all concerned interest groups. Internal couloirs are negotiated in a general on-site assembly involving all stakeholders (farmers, breeders, women’s groups, local authorities). For the demarcation of external couloirs the involvement of transhumance herders and neighboring villages is indispensable. Once an agreement on the course of the couloir is achieved, demarcation with stones and/or boundary planting with selected tree species is carried out by the local land users - with financial and technical assistance of the government or NGOs. Common species involve: Euphorbia balsamifera, Acacia spp. (A. nilotica; A. senegal); and Faidherbia albida. Management committees at the community level draw up regulations for the management of the couloirs (maintenance and protection of vegetation). Protection of plants is achieved through dead branches (at the initial stage), daily control by forest guards, and information campaigns. The technology is a sustainable solution to the described conflicts. As a valuable by-product the trees along the demarcation lines provide of wood and non-woody by-products.

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？
Implementation constraints: plant production is very expensive and reaching a consensus on the transformation of private cropland to communal passageways is very difficult	definition of the couloirs as public infrastructure and enhancement of organizational capacities of the local population through training and information sessions
Maintenance constraints: maintenance can only be realized by adjacent land owners, as the community organizations are weak	reinforce the institutional capacities of livestock owners and farmers to manage the couloirs
In the pastoral zone the couloirs lead to conflicts between pastoralists and private ranches	establish community-based land tenure commissions and introduce new laws on land property in the pastoral zone
