Oui

Commentaires:

Makurian rangeland is in bad condition. The land is largely degraded and dominated by the invasive species "Opuntia". Makurian Group Ranch has abandoned the in 2007 implemented "Holistic Management" principles. However, one has to take into account that Masai pastoralists have historically been squeezed from all sides into smaller areas. Compare Herger (2018).

2.1 Courte description de la Technologie

Définition de la Technologie:

The grazing principles of a Masai group ranch (pastoralists) deal with high numbers of livestock in semi-arid lands with very limited water resources. Makurian has abandoned "Holistic Management" principles and applies a more traditional management system today. There is a grazing plan for the rains, while during the dry season everybody seeks for water and pasture individually. Bare land is recovered by "Boma” technology (strategic corralling of animals overnight) and reseeding. The rangeland is due to high stocking rates severely degraded with lots of erosion, bare ground, and invasive species. High stocking rates have on the one hand historical and political reasons and on the other hand socioeconomic rationales.

2.2 Description détaillée de la Technologie

Description:

On Makurian Masai Group Ranch, livestock production management is through a combination of traditional livestock keeping practices and newly introduced management principles. Livestock production at Makurian is for subsistence and local use, and has very high cultural significance.
During the wet season, livestock are “bunched” together and rotational grazing in blocks is practiced. The management team (elders) group all livestock from each village (16 villages) and each uses the block next to their village. Livestock are hardly separated (cows, heifers, steers, bulls all herded together).
o Block 1: Lower Makurian - 1 month
o Block 2: Makurian Loruko - 2 weeks (next to Lolldaiga Northern Gate)
o Block 3: Munishoi Noosidan - 2-3 months
o Block 4: Mukogodo Forest - 1-2 months
o Block 5: Orieteti Conservation Area - 3 weeks. Soft grass, runs out quickly.
o Block 6: Ol Kinyei Mulango - 2 weeks. Next to Olenaisho
They apply resting periods of three months after usage (if this rule is broken, the owner is punished by a fine of one livestock unit).
When it becomes dry, everyone is responsible for their own livestock. Owners of livestock want to maintain and decide about their livestock individually, this is why "Holistic Management" and specific grazing plans for the dry season did not work.
In comparison to earlier days when the whole family moved, and livestock was herded by morans (young warriors), they hire external herders nowadays (800 herders in total). Herders seek whatever water and pasture remains on the group ranch, then move on to:
(a) Ngare Ndare forest: 1,000 cattle and 1,000 sheep and goats (shoats) per year on average, for 1-2 months, over an area of 250 km2;
(b) Mukogodo forest: 3,000 cattle and 4,000 shoats per year on average, for 3-4 weeks, over 250 km2, and
(c) Mount Kenya: 12,000 cattle and 5,000 shoats on average per year, for 1-2 months, on an undefined area.
In Mukogodo forest, Makurian Masai have also officially settled, in Ngare Ndare forest on the other hand they graze on the basis of an informal agreement and on Mount Kenya it is not official pasture - but grazing is tolerated). They are also assisted by private ranches to graze during droughts (Lolldaiga and Borana; for every 1,000 units, they usually pay 5 Ksh per cow per month: a token amount). On one private ranch (Borana) they also graze steers and cows for fattening and selling.

Furthermore, Laikipia rangelands support some of the highest densities of wildlife in Kenya, however, group ranches less so than private ranches. The wild herbivore biomass density on group ranches is by Georgiadis et al. (2007) estimated at 205 ha /TLU.
Bomas (corrals in Kiswahili) for the livestock are constructed in traditional style, where animals are kept closely bunched together in enclosures overnight. Bomas are strategically located on denuded land to rehabilitate the land (through dung accumulation and breaking the soil crust by hoof action). Every homestead has one boma (approximately 1,500 in total in the whole Group Ranch). When herders are moving with livestock, temporary bomas are constructed.
Sales are usually need-driven (e.g. for school fees) within a family. They sell to the nearest local markets (in DolDol and Nanyuki) or directly to butchers. Makurian is also part of the "Dung Market" in Mukogodo District, where livestock dung is sold as manure for crop production. Moreover, Makurian makes additional income by harvesting sand and selling it for construction.

Commentaires:

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 caused (partly) by livestock production in the research area are: 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 (Makurian is heavily affected by the invasion of Opuntia strica species). The current major problem on rangelands is the invasive species Opuntia stricta, which, however, only could spread that widely because of degraded land in the first place. The technology aims at improving vegetation cover of the land and thereby reducing further degradation and restoring degraded land.

All listed impacts are as perceived by land users according to Milton Sepeika, Chief of Makurian. In his opinion, abandoning Holistic Management principles had many advantages. According to him, animal production has increased. Though he recognices the bad condition of the land and poor conditon of livestock. He mainly blames the drought and the Opuntia invasion for these problems. Results from a rangeland health assessment (only ecological conditions) show heavily degraded ecological conditions (dry season up to 70% bare soil, poor soil and vegetation, erosions features, inability of producing annual and perennial grasses after rains etc) (compare Herger 2018).

Oui

Si oui, indiquez à quel changement la Technologie s'est adaptée:

• changements/ extrêmes climatiques

Spécifiez l'adaptation de la Technologie (conception, matériaux/ espèces, etc.):

Masai people have changed their livestock composition towards owning more smallstock (goats and sheep) than cattle. Goats are tolerant to drought, and as browsers they don't need grass. They can be turned into money much quicker than a cow in times of need. Their faster reproductive cycle means they can rebuild numbers faster than cattle after losses through drought.
