1.4 SLM技术问卷的参考
2. SLM方法的描述
2.1 该方法的简要说明
Public and private stakeholders in Namibia cooperate in the implementation of a national Bush Control and Biomass Utilisation programme. The programme consists of the three components (1) Creation of an enabling framework, (2) Advisory Services and (3) Value Chain Development.
2.2 该方法的详细说明
该方法的详细说明:
Public and private stakeholders in Namibia cooperate in the implementation of a national Bush Control and Biomass Utilisation programme. It is a response to the immense challenge of bush encroachment in the country.
Namibia is affected by bush encroachment on a massive scale. The phenomenon currently affects some 45 million hectares of farmland in 9 of the country’s 14 regions. Bush encroachment has lowered the livestock capacity of rangeland by up to two thirds. It further results in severely reduced biodiversity and limits the recharge of groundwater.
Various factors contribute to the accelerating rate of bush encroachment in Namibia. A primary cause of bush encroachment of savannas is overgrazing by livestock. When overgrazed, the grass layer loses its competitive advantage and its ability to utilise nutrients and water efficiently. Higher infiltration of water and nutrients into the sub-soil results, which in turn benefits bush and tree species, allowing them to dominate.
Another important theory is the state-and-transition model, which states that savanna ecosystems are event-driven, where rainfall and its variability impact on vegetation growth and its composition. This model implies that bush encroachment is not a permanent phenomenon and that a savanna can be changed to its grass-dominated state by favourable management or environmental conditions. Woody plants establish themselves after dry periods followed by a few wet years, and then maintain themselves by utilising most of the water. Rather than a gradual annual increase in numbers, the general rule is that woody plants establish in large numbers during certain years and at varying intervals.
Other factors contributing to bush encroachment are the reduction in the frequency of wildfires as well as the absence of browsers (e.g. through fencing of farms and replacing the natural composition of wildlife by cattle or smallstock).
Bush encroachment is accompanied by a change in the dominant grasses: perennial grasses are often lost, being replaced by annual species often of inferior quality for livestock. Annual grasses are generally less productive than perennial grasses. Thus, animal production on an annual grass sward is very precarious and less sustainable.
Despite the negative impacts, the encroacher bush has developed into a huge biomass resource, estimated at about 200 to 300 million tonnes. Measures used to combat bush encroachment create positive opportunities for the Namibian economy, such as the use of the resource for electricity generation and value chain development in other sectors. Bush harvesting therefore offers the potential to increase agricultural productivity, economic growth, employment and energy security, without competing with food production.
In line with the national development plans, the approach aims to strengthen the restoration of productive rangeland in Namibia. It identifies value chain opportunities to trigger large-scale bush thinning activities. Its focus is closely aligned to the National Industrial Policy of 2012 and the Growth at Home Strategy, which promote domestic value addition for local resources. The project will foster institutional development in the biomass sector and provide support to improve the legal and regulatory framework for large-scale bush control.
The programme consists of the following three components:
(1) Creation of an enabling framework: harmonisation of sector policies and improvement of relevant regulations; strengthening of institutional capacities.
(2) Advisory Services: strengthening of existing farmer outreach services and knowledge dissemination to farmers, businesses and public sector decision makers.
(3) Value Chain Development: identification and piloting of relevant value chains for encroacher bush as a trigger for bush control.
The programme is implemented in collaboration of various public and private sector stakeholders. Its coordination is ensured through a cross-sector steering committee, which includes the line ministries of the following sectors: national planning, agriculture, environment, energy, industrialisation.
Key outputs of the programme include:
Enabling Environment:
- Strategic Environmental Assessment (SEA)
- Introduction of Harvesting Authorisations Guidelines
- Development of dedicated financial products (loan subsidy schemes).
Institutions:
- Introduction of the De-bushing Advisory Service (DAS)
- Introduction of the Namibia Biomass Industry Group (N-BiG).
Knowledge:
- Compilation of baseline data on bush encroachment and bush control
- Technical know how on technologies
- Compilation of relevant regulations and environmental principles.
Value Chain Development:
- Piloting of various value chains, including modernised charcoal production, bush based animal feed and household cooking fuel.

Cross-sector cooperation through steering committee |
Involvement of private sector as driving force for implementation |
6.5 该方法的弱点/缺点以及克服它们的方法
土地使用者认为的弱点/缺点/风险 | 如何克服它们? |
---|---|
Limited direct (financial) support | Introdution of incentive schemes |
Limited opportunities in remote areas, i.e. when distance to biomass off-takers is too large | Further development of on-farm solutions (e.g. bush-to-feed) |
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? |
---|---|
Complex programme steering requirements, due to multi-sector relevance. The national programme for Bush control and Biomass Utilisation is currently anchored in the Directorate of Forestry (DoF) of the Ministry of Agriculture. This adequately accounts for the fact that the bush resource is part of the national forestry/biomass resource and its utilisation must be regulated as such. However, this anchoring does not allow for an effective promotion of biomass utilisation (e.g. SME promotion, industrialisation concepts, development of logistics hubs) and innovative end-uses (e.g. development of biomass power plants). For this purpose other line ministries, such as Ministry of Mines and Energy (MME) as well as Ministry of Industrialisation and SME Development (MITSMED) are part of the programme's steering committee. | Establishment of national coordinating body to formalise the current steering committee |
