注释:

The technology is a sustainable land management practice that had been used for time immemorial by Boran pastoralists to manage land and land-based resources.

2.1 技术简介

技术定义:

The Dedha grazing system is an ancient, traditional governance system for land and its resources practiced by Boran pastoralists. It carefully balances how pastoralists use rangeland resources. The basis of the technology is three grazing rangeland governance zones: wet season grazing, dry season grazing, and drought reserves. There is also water governance based on a traditional hierarchy of rights. Through this system, Boran pastoralists adapt to severe and recurrent droughts.

2.2 技术的详细说明

说明:

This grazing system is applied in Isiolo County, Northern Kenya. The Waso rangelands are inhabited by Boran pastoralists with Somali, Samburu, Rendille and Turkana herders sharing cross-border resources through negotiation. The technology is based on the maintenance of a delicate balance between livestock numbers, the supply of water, and the amount/ quality of standing pasture within the vast grazing area which is water scarce and prone to extreme seasonal variations. Through its main tenet of governing grazing patterns (wet, dry season grazing area and drought reserve) planned use of pasture is decided in large pastoralists’ assemblies attended by elders from a particular “Dedha” (a grazing area, which administratively can be as big as two wards). This process is complicated by dry seasons and droughts of unknown length, with pressure from the community to open grazing reserves. Wrong decisions can spell the end of livelihoods for some families. An ability, which has been gradually eroded over time and by external factors which don’t understand its enormous benefit but there is a project which is using an integrated approach to revive and empower this system.
The Jars a Dedha use water points to manage grazing. Different types of water sources need specific forms of management. The most intensive management occurs during droughts at deep wells and boreholes which require the most labour to operate and maintain, and are the most reliable sources of water. Due to the strategic importance of these resources, management falls to the Jarsa Dedha (council of elders). The use of shallow wells is tightly controlled by both the aba ella (the person who first dug it) and aba erega (the owner of the rotter ) working together. Aba ella is assigned first rights to water. If there is spare capacity then ‘second rights’ are decided by aba erega. Second rights would typically fall to those of a different clan, while ‘third rights’ might fall to a different ethnic group. The Borana customs and culture defines both access to certain wells but also the order of priority for watering animals.
In addition, in consultation with the Dedha council of elders, aba erega manages the use of dams and access to rivers. Generally, use of flowing river water is restricted to the dry season and access is limited to designated watering points. These are located some distance downriver from settlements to minimize disruption to inhabitants and to reduce contamination. Temporary water sources during and after the rains are not subject to control except when their use conflicts with restrictions on grazing areas. After watering their livestock, pastoralists traditionally fill their troughs for wildlife at night. This is intended to prevent wildlife from falling into wells - and to seek God’s blessings.
The high variability of rainfall in pastoral areas leads to similarly variable pasture availability. Therefore, management of grazing resources needs to balance maximizing productivity while ensuring survival. Long-term viability of the system depends on the maintenance of adaptive traits within local breeds, and both maintaining and managing resources strategically. Only within these broader goals is the concept of ‘maximizing productivity’ meaningful.
Mature livestock (gues) which are not lactating are moved to remote pastures. The gues, which make up the majority of community livestock, are herded by young unmarried men. By utilizing remote pastures, grazing resources closer to permanent water sources can be preserved for the dry season and droughts. Pasture within the vicinity of homesteads (maar qaae – literally ‘near grass’) is protected from grazing by non-lactating livestock (this is similar to kalo but a kalo reserve need not be next to the homestead ). This pasture is set aside for young animals (calves, lambs, and kids). Migrating livestock have predefined routes that maintain distance from maar qaae. The Dedha council of elders, therefore, controls settlement patterns to preserve key migratory routes. Movement of livestock between different Dedhas must be prearranged with the respective Dedha council of elders who assess spare capacity in terms of water and grazing.
The floodplain grazing area (chaafa) is crucial because it acts as a refuge for livestock during extreme drought. Grazing in chaafa is strictly prohibited during the wet season and one of the critical decisions for the Jarsa Dedha is when to open chaafa after rains have failed. Due to the relatively moist conditions in chaafa, there are additional challenges to animal and human health: namely trypanosomiasis, ticks, pneumonia, and malaria. Jarsa Dedha make decisions primarily concerning seasonal movements from wet to dry season grazing and also the opening of boreholes and chaafa. The overwhelming local consensus is that efficient resource use depends on the ability ofJarsa Dedha to enforce these regulations

技术规范（与技术图纸相关）:

The technology is implemented in a vast area of rangelands in Isiolo County which covers around 20,000 km2 inhabited by Boran pastoralists under common management of Isiolo Jars Dedha (Council of elders). The rangelands are subdivided into around 14 arthas (localities) which are separately managed by artha elders and within which there are also ollas (homesteads) which the elders oversee. The elders manage key resources that are essential for pastoral livelihood. The resources are; prime pasture/grazing areas, water points e.g. streams, rivers, springs, shallow wells and pans, wildlife, forests, minerals, sand and other valuable stones e.g. gemstones (bojimine) and quarry, Trees and their products e.g. makuti, medicinal herbs, wild, fruits, resins, gum arabic.
