2. Descrição da abordagem de GST
2.1 Descrição curta da abordagem
Integrated land and water management approach, including vegetative, management, and agronomic measure
2.2 Descrição detalhada da abordagem
Descrição detalhada da abordagem:
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.

2.7 Tipo de abordagem
- Iniciativa/inovação local recente
2.8 Principais metas/objetivos da abordagem
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 Condição que propiciam ou inibem a implementação de tecnologia/tecnologias aplicada(s) segundo a abordagem
Disponibilidade/acesso a recursos e serviços financeiros
- Inibitivo
High cost investment
Treatment through the SLM Approach: Public projects (National strategy of SWC), subsidies
Quadro institucional
- Inibitivo
Land fragmentation, complexity of land tenure,
Treatment through the SLM Approach: Users organisation, participation
Quadro jurídico (posse de terra, direitos de uso da terra e da água)
- Propício
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. Participação e papel das partes interessadas envolvidas
3.1 Partes interessadas envolvidas na abordagem e seus papéis
- Usuários de terra/comunidades locais
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.
- Especialistas em GST/ consultor agrícola
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.
- Governo nacional (planejadores, responsáveis pelas decisões)
- Organização internacional

3.3 Fluxograma (se disponível)
Descrição:
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).

Os usuários da terra podem manter o que foi implementado através da abordagem (sem apoio externo)?
- Incerto
Caso negativo ou incerto, especifique e comente:
Can given the recent escalation in payments made to land users for implementation under certain projects it seems that the costs will be too high to sustain. Currently the Ministry of Agricultural is demanding that in-depth cost-benefit analyses are carried out involving environmental, social as well as economic assessments

Pontos fracos/desvantagens/riscos na visão do usuário da terra | Como eles podem ser superados? |
---|---|
Abandonment of the works, less maintenance | Continue to support farmers and local institution and organisation. Repairing and maintaining in time. |
Low impact on livelihood conditions | improve efficiency of SWC activities and participatory approach |
Pontos fracos/vantagens/riscos na visão do/a compilador/a ou de outra pessoa capacitada | Como eles podem ser superados? |
---|---|
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. |
