2.1 技术简介

技术定义:

The technology is based on tree plantation of several species (i.e. Grevillea robusta, Psidium guava, Bambusa vulgaris ) along the riparian land of the farmer.

2.2 技术的详细说明

说明:

The practice carried out voluntary by the farmer consists of planting trees at the edge of the river bank and in its proximity.

Purpose of the Technology: By increasing vegetation cover (started 10 year ago) the intention of the farmer is to reduce and control bank erosion and landslides in the riparian land.
The degradation in this area is in fact evident and it is partially explained by the reduced vegetative cover. The planted trees help to maintain water quality by filtering silt and organic materials from rainwater runoff from the upper area and at the same time reinforce the streambank to control erosion. Another important environmental benefit is the increased carbon allocation from the new root systems.
The farmer also mentioned the interest to continue expanding tree plantation also in view of carbon credit and financial support from local authorities: in particular bamboo, which reaches maturity in few years, can be harvested after about two years and is easy to propagate (vegetatively).
Grevillea trees (timber) are seen by the farmer as a form of saving, and sold out when the farmer is in need of cash, earning between 800 up to 1500 KSh (Kenyan Shillings), depending on the size of the tree and the costs for cutting- transportation (e.g. machine operator between 500-700 KSh).

Establishment / maintenance activities and inputs: The initial inputs for the establishment of the vegetative practices concern mainly labour (e.g. planting trees) and the cost of the seedlings (10 KSh seedlings of Grevillea, 20 KSh of Guava); generally these activities are carried out at the beginning of the rainy season. Pruning of Grevillea is done every three seasons.

Natural / human environment: The climate is sub humid with two rainy seasons (the first starts around March and the second around October). Near the river the area is characterized by gentle slope and deposition of sediments and bank erosion are the main processes; the risks of further degradation and water pollution are reduced by the riparian vegetation and thanks to the good land management practices of the surrounding farmers. The riparian land is the area of min 6-30 m around the river and it is considered by law a protected area; therefore it should be left intact from any human activity (Water Act, 2002). Indeed, the 'control' and daily management is carried out by the riparian farmers in collaboration with Sabasaba WRUA and WRMA, the official authority for the management of the water of the river and the riparian land.
In this site in particular, the water of the river is considered clean by the farmer interviewed, despite the fact that during rainy seasons the sediment loads affect the quality of the water.

• 减少、预防、恢复土地退化

3.2 应用该技术的当前土地利用类型

注释:

Tree plantation of several species (i.e. Grevillea robusta, Psidium guava, Bambusa vulgaris )

Major land use problems (compiler’s opinion): Risk of bank erosion and deposition of sediments in the river. See Appendix 3. Fig. 2.

Major land use problems (land users’ perception): Bank erosion. See Appendix 3. Fig. 3

Other type of forest: few lines of Grevillea/Bamboes: According to the definitions adopted FAO (FRA, 2010) the land could not be considered as wooded land (less than 0.5 ha).

Problems / comments regarding forest use: Bamboos are planted because of environmental benefits of this plant to stabilize riverbank. Other potential uses: e.g. wood is used to make baskets, fences and various kind of construction; leaves are used to feed chickens. The hollow sections between nodes are used to make containers. Indeed, the farmer let neighbours to clear and use some bamboos.

Forest products and services: nature conservation / protection

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
Grevillea is good for timber producion. How can they be sustained / enhanced? More trees could be planted, but because of 'lack of money' he can not afford it.
Bamboos are good in holding the soil How can they be sustained / enhanced? Leaves could be actually used to feed chickens; planting the 'giant bamboos' also for food consumption.

编制者或其他关键资源人员认为的长处/优势/机会
The Technology is easy to adopt, specially Bamboos plantation, since it does not require significant input and knowledge How can they be sustained / enhanced? It could be implemented in the long run also because the farmer is willing to earmark part of his land for a nursery. The intention is to support the nursery with free seedlings, which could be later distributed among the riparian farmers of the community.
Bambos spreads easily through cuttings and it has different beneficial uses (baskets, fences and various kinds of construction). How can they be sustained / enhanced? Other type of Bamboos could be used as: Dendrocalamus giganteus for food consumption and Arundinaria alpina.
Grevillea plantation has benefits in holding soil. It helps to reduce evaporation from the soil since it makes good shadow. How can they be sustained / enhanced? To increase biodiversity other indigenous sps. could be also planted, among others: Croton megalocarpus (Mũkindũri) a medicinal tree that attracts a lot of bees when in flower, resulting in excellent white honey. The seeds contain oil. Sesbania sesban/keniensis (Mwethia), a nitrogen fixers plant which therefore helps to increase soil fertility.
