2. SLM方法的描述

2.1 该方法的简要说明

Integrated land and water management approach, including vegetative, management, and agronomic measure

2.2 该方法的详细说明

该方法的详细说明:

Aims / objectives: The overall purpose of the approach is to prevent soil and water loss by combined measures and to provide a better environment. Soil and water conservation (SWC) technologies, based on harvesting area of surface water and underground water, are implemented to conserve soil and water and to improve the production and the biodiversity.

Methods: This approach is designed for the exploitation of water runoff for agricultural development, particularly for fruit trees cropping (mainly olives).This can be achieved through erosion reduction and aquifer recharge via runoff water infiltration into the terraces, slope angle and length reduction, runoff retaining, infiltration increase and soil loss reduction. The system is based on various runoff water harvesting systems, as jessour, tabias. It is marked by fruit tree development, notably olives. On the terraces, the fruit trees are arranged in inter-rows with the three main species encountered in the study areas. Generally, olive trees are planted, with in between rows almonds and/ or fig trees. SWC technologies play an importance role in arid zones. Since the 1970s, the Tunisian state has encouraged the local population to conserve water and soil in arid zone. Successive programmes and strategies of water and soil conservation have been developed and were implemented in all three natural regions of Tunisia (North, Centre and South).These techniques can be implemented by farmer with governmental subsidies or by government intervention in the projects and programmes of water and soil conservation. During the last decade, the Tunisian government implemented the first national strategy for soil and water conservation (1990-2000) and the second national strategy for soil and water conservation (2001-2011). These strategies mobilized important funds at national and regional levels. About 672.5 ha of SWC technologies were built and about 550 ha of SWC technologies are planned for the second national strategy.

Stages of implementation: 1) Assessment of the current natural resources and socio-economic conditions; 2) Proposition of actions at local and regional level; 3) Aggregation and coherence at the national level; 4) implementation of national action plan at local and regional level.

Role of stakeholders: Different levels of intervention are observed from the individual farm, through the community level, the extension / advisory system, the regional or national administration, or the policy level, to the international framework. The participative approach is usually applied in the construction of SWC technologies.

2.8 该方法的主要目的/目标

The Approach focused on SLM only (production, soil fertility, biodiversity, employement oppourtunities, food self-sufficiency, fixing population and stop farming exodus)

The objectives of the approach are to control soil and water loss to reduce floods and enhance fertility, to enhance rainfed agriculture productivity, to improve the livelihoods of farmers, to contribute to the production increase among farmers and pastoralists, to recharge the groundwater and to extend the area of cropland.

The SLM Approach addressed the following problems: The problems originate in the scarcity of water which is leading to conflicts over resource use between farmers. Oversized techniques leading to prevention of runoff from upstream to downstream reduce agricultural production and therefore the farm income, which causes a lack of cash to invest in SLM. In some cases irreversible land degradation is the result. The problems are mainly related to the lack of technical knowledge, the high costs of investment and the lack of tangible and assessable impacts of SWC activities, technically or socially.

2.9 推动或妨碍实施本办法所适用的技术的条件

财务资源和服务的可用性/可得性
  • 阻碍

High cost investment

Treatment through the SLM Approach: Public projects (National strategy of SWC), subsidies

机构设置
  • 阻碍

Land fragmentation, complexity of land tenure,

Treatment through the SLM Approach: Users organisation, participation

法律框架(土地使用权、土地和水使用权)
  • 启动

The existing land ownership, land use rights / water rights greatly helped the approach implementation: The approach helped in the privatization of the land and has therefore greatly reduced the land/water use rights problems. This in turn has rendered the local interventions much more efficient.

3. 相关利益相关者的参与和角色

3.1 该方法涉及的利益相关者及其职责

  • 当地土地使用者/当地社区

Working land users were mainly men (Men are the main force for field work.)

Special attention has been paid to make women participate in the approach. Nevertheless, men have much more technical knowledge and skills than women because if SWC technologies have to be constructed by manual labour, men can achieve more. Poor and old people are especially involved through their participation in the special programme against unemployment in rural area. Some unemployed young people may benefit from agricultural development programmes.

  • SLM专家/农业顾问

The choice on the technology to use is made primarily by the technical specialists based on the prevalent type of erosion on each farm and farmers preference.

  • 国家政府(规划者、决策者)
  • 国际组织
如果涉及多个利益相关者,请注明领导机构:

National and state specialists together with land users.

3.2 当地土地使用者/当地社区参与该方法的不同阶段

3.3 流程图(如可用)

具体说明:

The treatment of the catchment starts from the upstream and continues to piedmont areas, and ends in the downstream section of the catchment. Attention should be given to ensure sufficient water allocation to all the sections of the catchment as well as to the different users (rainfed agriculture and rangelands, irrigated areas, drinking water, industry and tourism).

Less confidence between partners and less participation improve dialog and communication; improve efficiency of SWC activities and participatory approach.
High costs: farmers depend on external support from the government; they are not willing to invest their labour without payments New approach should give farmers loans for construction as now they use machines to do the work. In addition, search for cheaper SWC technologies and for improving the benefits.
