  • Kajiado County 2020 Short Rains Food and Nutrition Security Assessment Report
    KAJIADO COUNTY 2020 SHORT RAINS FOOD AND NUTRITION SECURITY ASSESSMENT REPORT February 2021 A Joint Report by Kenya Food Security Steering Group (KFSSG) and Kajiado County Steering Group (CSG) EXECUTIVE SUMMARY The 2020 Short Rains food security assessment was carried out by the county technical team with technical support from the Kenya Food Security Steering Group (KFSSG). The overall objective of the assessment was to objectively and with evidence provide food security situation in the county in a transparent manner following the 2020 Short Rains taking into account the cumulative effect of the previous seasons. The assessment provides recommendations for possible response options based on the situation analysis upon building consensus. Both quantitative and qualitative approaches were used during assessment including review of the existing data provided through checklists or otherwise and triangulating with field observations as well as both community and key informants interviews. Depressed rainfall was the key driver of food security in the county which resulted in below normal regeneration of pasture, recharge of water sources and crops yields. The COVID-19 epidemic negatively affected patterns of food supply and access as well as health- seeking behaviour in the county. Livestock diseases were also an important food security driver in the county. Since May 2020, livestock prices were sustained above the Long Term Average due to the reduced supply to the markets. Following the off-season rains in early January 2021, domestic water consumption has now normalized. Nutrition status of under-fives was better for the entire year as evidenced by the below long term average risk of malnutrition of 6.8 percent.

  • Driving Directions
    Routes from Nairobi to Rhino River Camp (by road). (Consider a six hours drive). From central Nairobi (via Museum Hill) take Thika road. Past Thika and before Sagana there is a junction: to the left the road goes towards Nyeri and Nanyuki, to the right it goes to Embu. First option: going left toward Nyeri-Nanyuki. Drive through Sagana, then Karitina. After 13 kms, there is a junction where you should turn right. At junction, instead of going straight to the road bound to Nyeri, take the road towards Naro Moru and Mt. Kenya. After Nanyuki proceed straight to Meru. The only major junction in the road Nanyuki-Meru is the one going to Isiolo which you disregard and proceed straight to Meru Town. At Meru Town, at the first major junction (see Shell station on your left), turn left toward Maua. After driving about 45 kms over the Nyambeni hills on this road find the junction at 2 km before Maua. This junction is plenty of signposts one of which is a KWS sign with Meru National Park. Turn left and start descending towards Meru National Park; proceed for 25 km until Murera Gate (main gate) of the Park. In the Park: Enter the Park and go for about 1.5 km till you reach the old gate. Do a sharp right turn immediately after the old gate (in fact is more of a U turn) and enter the Rhino Sanctuary passing under an elephant wired fence. Follow the Park fence going South. The fence is on your right and there are a few deviation but you have to always go back to the fence.

  • Sediment Dynamics and Improvised Control Technologies in the Athi River Drainage Basin, Kenya
    Sediment Dynamics in Changing Environments (Proceedings of a symposium held 485 in Christchurch, New Zealand, December 2008). IAHS Publ. 325, 2008. Sediment dynamics and improvised control technologies in the Athi River drainage basin, Kenya SHADRACK MULEI KITHIIA Postgraduate Programme in Hydrology, Department of Geography and Environmental Studies, University of Nairobi, PO Box 30197, 00100 GPO, Nairobi, Kenya skithiia@yahoo.com Abstract In Kenya, the changing of land-use systems from the more traditional systems of the 1960s to the present mechanized status, contributes enormous amounts of sediments due to water inundations. The Athi River drains areas that are subject to intense agricultural, industrial, commercial and population settlement activities. These activities contribute immensely to the processes of soil erosion and sediment transport, a phenomenon more pronounced in the middle and lower reaches of the river where the soils are much more fragile and the river tributaries are seasonal in nature. Total Suspended Sediments (TSS) equivalent to sediment fluxes of 13 457, 131 089 and 2 057 487 t year-1 were recorded in the headwater areas, middle and lower reaches of the river, respectively. These varying trends in sediment transport and amount are mainly due to the chemical composition of the soil coupled with the land-soil conservation measures already in practice, and which started in the 1930s and reached their peak in the early 1980s. This paper examines trends in soil erosion and sediment transport dynamics progressively downstream. The land-use activities and soil conservation, control and management technologies, which focus on minimizing the impacts of overland flow, are examined to assess the economic and environmental sustainability of these areas, communal societal benefits and the country in general.

  • Flash Update
    Flash Update Kenya Floods Response Update – 29 June 2018 Humanitarian Situation and Needs Kenya Country Office An estimated 64,045 flood-affected people are still in camps in Galole, Tana Delta and Tana North Sub counties in Tana River County. A comprehensive assessment of the population still displaced in Tana River will be completed next week. Across the country, the heavy long rains season from March to May has displaced a total of 291,171 people. Rainfall continues in the Highlands west of the Rift Valley (Kitale, Kericho, Nandi, Eldoret, Kakamega), the Lake Basin (Kisumu, Kisii, Busia), parts of Central Rift Valley (Nakuru, Nyahururu), the border areas of Northwestern Kenya (Lokichoggio, Lokitaung), and the Coastal strip (Mombasa, Mtwapa, Malindi, Msabaha, Kilifi, Lamu). Humanitarian access by road is constrained due to insecurity along the Turkana-West Pokot border and due to poor roads conditions in Isiolo, Samburu, Makueni, Tana River, Kitui, and Garissa. As of 25 June 2018, a total of 5,470 cases of cholera with 78 deaths have been reported (Case Fatality Rate of 1.4 per cent). Currently, the outbreak is active in eight counties (Garissa, Tana River, Turkana, West Pokot, Meru, Mombasa, Kilifi and Isiolo counties) with 75 cases reported in the week ending 25 June. A total of 111 cases of Rift Valley Fever (RVF) have been reported with 14 death in three counties (Wajir 75, Marsabit 35 and Siaya 1). Case Fatality Rate is reported at 8 per cent in Wajir and 20 per cent in Marsabit. Active case finding, sample testing, ban of slaughter, quarantine, and community sensitization activities are ongoing.

Rainfall data was obtained from 26 stations in Kenya, out of total 34 synoptic stations which were analyzed at monthly, seasonal and annual scales. Monthly Climate Research Unit (CRU) and Global Precipitation Climate Centre (GPCC) data sets were used. Results showed that CRU data performs better than GPCC when subjected to evaluation and comparison with station data. The findings showed that the highest and lowest annual rainfall was recorded in 1997 (1309.1.2mm) and 2000 (609.4mm) respectively. Maximum mean annual rainfall (2087.0mm) was observed on Kisii station, while the least mean annual rainfall (203mm) was reported at Lodwar station. The highest recorded total rainfall within the analysis domain occurred at Kisii location (3673.6mm), while the least was recorded at Lodwar location (54.2mm). Further results reveal that among the seasons, a noticeable decrease in March, April and May (MAM: 95.5.0mm) and slight increase in October to December (OND: 65.3mm).
