2.1 技术简介

技术定义:

Borana is a private ranch which combines livestock production with conservation and tourism. "Holistic Management" is applied as a principle for livestock on semi-arid lands with limited water resources. Grazing comprises “bunching” and rotational movement of all animals in herds.

2.2 技术的详细说明

说明:

Livestock production on Borana ranch is carried out under extensive grazing for beef, dairy, and sheep production. There is strategic fattening and offtake for sales in harmony with conservation principles. The Borana Conservancy is a non-profit organisation, also belonging to the ranch – on the same land - dedicated to the sustainable conservation of critical habitat and wildlife. Ranching contributes financially to the running of the conservancy.

“Holistic Management” (HM) as described by Allan Savory (1988) and promoted by Laikipia Wildlife Forum in Laikipia, is a method that integrates decision-making, planning, and livestock keeping. On the land, this means bunching of all livestock close together in order to act as a "plough" and break the soil to help incorporate seeds and nutrients. Water also infiltrates better. The aim is to improve plant growth and thus soil. Furthermore, it means moving the animals together from block to block, by planned rotational grazing with resting periods. HM aims at managing high numbers of livestock and simultaneously restoring degraded land. However, Holistic Management principles remain controversial.

Livestock herders employed by Borana move different herds of animals rotationally from one grazing area to the next. A defined grazing area lasts for around two months, with a resting period of six months. However, the grazing area and period vary a lot depending on rainfall. During the wet season, livestock usually spend more than two months within the same block. Cattle herds are split depending on their function as offtake for sales, or as breeding stock. The selling stock is located on the eastern side of Borana (currently 600 Head of cattle), while the breeding stock is on the western side (currently 1,800 Head of cattle). Sheep are grazed on the western side too (currently 1,200 Head of cattle).
A calf stays with its mother until it is about six months old. Then a few males are selected as bulls, and all others castrated. At the same time females are selected for breeding to rebuild stock. Only one bull was purchased from outside, in 2013 which was a rare exception.
Livestock are sold to butchers in local centres (e.g. Nanyuki, about 50 km distance), in the capital Nairobi (about 300 km away), and to the son of the owner, who runs a business nearby. Usually, only old and disabled cows are selected for selling.
Borana helps neighbouring group ranches with improved genetics - and access to their land for fattening purpose. It also acts as a grass bank during droughts. According to Borana management, boundaries between Borana and community ranches, which once clearly defined the difference between managed and over-grazed lands, are becoming less clear.
Typical of private ranches in Laikipia, Borana supports some of the highest densities of wildlife in Kenya. The wild herbivore biomass density on private ranches is estimated by Georgiadis (2007) at 14 ha /TLU.

3.6 包含该技术的可持续土地管理措施

3.7 该技术强调的主要土地退化类型

注释:

Across the grasslands and rangelands, an increase in bare land and bush has been a clear trend all over Laikipia for many years, both on community-owned lands and private ranches. Major identified ecological problems (partly) caused by livestock production are: bare ground, low contents of soil organic carbon and plant-available nutrients, soil erosion (sealing, crusting, rills and gullies, water flow patterns, sheet erosion, pedestals), poor soil properties, undesirable species, and (increasing) woody and invasive species. The technology aims at improving vegetation cover of the land and thereby reducing further degradation and restoring degraded land. Borana is clearly not as much affected by the degradation of the land (compare Herger 2018), however, they use and support ranching with Holistic Management as a tool to enhance the quality of the grazing and prevent degradation. According to Borana management, cattle grazing reduces the moribund grass biomass, promotes seed dispersal, increases the nutritional value of the grass, and decreases the risk of bush fires. Even more crucial: The introduction of planned grazing (as Holistic Management) to Group Ranches in the area prevents conflicts (e.g. invading of private ranches), livestock diseases and deaths.

Government states the land belongs to the private ranchers, but the future development is unknown. There have already been conflicts and are likely to happen again. On the other hand, cooperation with group ranches has increased.

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
Method leaves grass time to grow/rest
One can manage resources properly (water and pasture)
To keep all animals in one place makes vaccinations /disease prevention easier
“Ploughing effect” by the concentrated / bunched animals in one herd (new grass stimulated)
Tick population kept under control
In general for the whole area if many Group Ranches implement Holistic Management: More secure financial future and less stress during times of drought for pastoralists’ livestock. For Borana, this means less pressure from surrounding pastoralists when pasture is scarce.
Enhance the quality of grazing. Cattle grazing reduces the moribund grass biomass, promotes seed dispersal, increases the nutritional value of the grass and decreases the risk of bush fires.

编制者或其他关键资源人员认为的长处/优势/机会

The listed advantages from Abdi Sora, land user, are for the most part shared by the compiler's view. Regarding Holistic Management (HM) principles and land recovery there remain some uncertainties. On the one hand it is generally questionable to state as in HM that: “the more animals the better” (as long as they are managed properly they can even recover degraded land), but this seems dangerous in areas with such high livestock numbers and cultural value of livestock keeping - without scientific proof of the principles in similar ecological conditions. Since Borana has relatively low stocking rates and good management the rangeland is in good condition anyway. The effects of Holistic Management principles on their own are difficult to estimate.
