Brève description et caractéristiques techniques de la technologie

The technology involves construction of stone lines along the contour line. Construction of diversion furrows above the fields in such a way that they gently divert runoff away from the fields to either a natural waterway or a constructed waterway where it will not cause any harm. Terraces are constructed in the fields to reduce the slope length, improve infiltration and to divert runoff from the fields.
Silt traps are constructed in the dongas and gullies to reduce water velocity and to trap silt that might have been carried on by runoff.
Grass planting is carried out on marginal lands and reseeding on heavily degraded rangelands which are thereafter protected from grazing for at least three years to recover fully.
Forest trees are planted in areas which have been carefully selected to avoid environmental damage that might be caused by exotic species. Soil binding trees are planted in gullies to reduce soil erosion. Fruit and other N-fixing trees are planted along the terraces to increase organic matter and enhance fertility.|
Stone lines are surveyed using either the line-level or dumpy level in order to follow the contour line of the catchment area. They are constructed using locally available materials such as stones. These stones are lined in such a way that they are 0.3 m high and 0.4 m wide with maximum length of 150 m. They are contructed on tide slopes with intervals depending on the steepness of the slope.
Diversion furrows are surveyed using either the line-level or dumpy level in order to determine slope of the furrow adequate for diverting runoff collected from the catchment. They are usually constructed such that they are 0.5 m deep, 1 m bottom width and 1.5 . top width with a maximum length of 150 m. They are constructed from outlet to prevent any damage that might occur in the case where it rains before completion. If needed the next diversion furrow is constructed 5 m above the first with an overlapping distance of 5 m to prevent runoff bypassing the lower part.
Silt traps are surveyed using line level or dumpy level to determine spacing in gullies and are constructed inside gullies or dongas.
Their maximum height is 1 m, width is 0.5 m and length across the donga or gully  depends on the width of the gullywhere they are constructed. Every silt trap should have a core width of 0.5 m and 0.5 m with a height of 1 m above ground. The structure should be 2:1. Intervals depend on steepness of the slope.
Soil binding trees are planted in gullies with less than 2 m apart whicle forest trees are planted in carefully selected areas. Forest trees are planted in a 3 m X 3 m interval/spacing to allow understory vegetation.
Grass planting on marginal lands is done using a cyclone seeder and reseeding in rangelands is done by digging small holes and the seeds are planted in this small holess and throough broadcasting.

Décrivez les impacts sur site (les deux principaux impacts par catégorie)

There has been less siltation of natural water bodies such as wetlands, dams and rivers because of sufficient vegetation cover and physical structures.|
Increased soil fertility which has led to improved soil moisture regime and vegetation cover.
Improved education as a result of availability of funds for fees from selling agricultural produce and products.
There is high carbon sequestration as a result of increased afforestation and improved vegetation cover.
There has been an overall improvement on crop yield, livestock (meat, wool and mohair) and a general increase in biodiversity.|
Conservation and harnessing of water through tank conservation has improved-livelihoods through small scale irrigation.
The activities in the catchment area have brought an aesthetic beauty which attracts neighbouring villagers and tourist.
It has been observed that the successful implementation of the activities brings conflicts of interest between neighbouring communities which at times result in vandalism.

Décrivez les deux principaux impacts hors site (dans les environs)

As a result of incentives offered in the project area, neighbouring villages do not feel obliged to volunteer to do land management activities.|
Integrated watershed management (IWM) has brought motivation and encouragement to neighbouring communities.

Impact sur la biodiversité et le changement climatique

Décrivez:

Water harvesting scheme is one of the adaptation as it provides supply of irrigation water throughout the year. Conservation farming practices such as minimum tillage contributes to climate change adaptation since they reduce compaction because there is no heavy machinery used and hence this improves infiltration and moisture regime. Mulching (stalk mulching) and the use of farm manure ass organic matter which improves water capacity of the soil.
IWM led to noticeable vegetation cover resulting in carbon sequestration. Land degradation have been reduced by the activities and these contribute to climate change mitigation. The impacts of drought have been reduced by vegetation cover contributing to improved infiltration and soil moisture.
The technology has a positive impact on biodiversity conservation as some of the species (flora and fauna) that were previously declared as threaten have reappeared. The wetlands and sponges that have dried up have also rivived as a result of integrated watershed management (IWM) practices.It has previously observed that some of the springs were only flowing during summer season. As a result of the best practice there is relatively prolonged yield of springs throughout the year. Furthermore, there ihas been refabrication of medicinal plants that were threatened due to overharvesting. An overall benefit to the catchment has been an improved biodiversity in general including soil biodiversity which has contributed much to the vegetation cover and aesthetic value of the catchment area.|

Incentives that were given to the communities in the form of food packages, fruit trees seedlings, equipment and allowances motivated them. This can be replicable with some level of adaptation.|
Involvement, collaboration and participation of local communities which promotes ownership and maintenance of the activities/structures involved in integrated catchment management(ICM). This can be replicable elsewhere. |
Highly motivated local authorities and target groups because of political will that guarantees them leadership positions in the community. This can be replicable with some level of adaptation.

Liées aux ressources humaines

Communities should be active stakeholders together with local authorities (Chief and Community Council)|Triple bottom line approach should be used and Community Action Plans (CAP) should be adopted. Communities should initiate and prioritise the activities. |Intergrated watershed management (IWM) is a learning process i.e. combination or collaboration of efforts with other ministries, NGOs and CBOs which is very important in making the practice a success.|Lack of transparency due to political preference sometimes lead to vandalism of activities.

Liées aux aspects financiers

Funds are limited and widely spread throughout the country, resulting in slow impact. Therefore, efforts should be concentrated in a smaller area where intensive work can be done which result in a larger impact.|Financial incentives overshadow the need to combat desertification/land degradation. This is shown in the non-maintenance and incompletion of structures after the incentives are gone.|Insufficient funds prevent regular monitoring of activities.  

Liées aux aspects techniques

Application of the technology is area specific i.e. soil, topography, climate etc.|It is very important to survey the soil and water conservation activities prior to construction.|Negligence of the technical specification of the activities/structures may lead to more damage to the land than before construction.
