2 Background of KMD Established in line with the World Meteorological Organisation (WMO) Convention as a colonial service for East Africa way back in 1929 KMD became a Department of the Government of Kenya in 1977 after the collapse of the East African Community (EAC). 2

3 The Main Objective of KMD To provide accurate and timely weather and climate information and services required for: the safety of life; protection of property; and conservation of the natural environment 3

4 HAZARDS A potentially damaging physical event, human activity or phenomenon with a potential to cause loss of life or injury, property damage, social and economic disruption of life, environmental degradation among other effect. These occur all over the world and are, on their own not harmful. However when these natural hazards interact with people, they are likely to cause damage of varying magnitude resulting in a disaster. 4

5 Major hazards in Kenya Kenya experiences a number of natural hazards, the most common being weather related, including: Heavy rains leading to floods, Dry spells leading to droughts, Heavy rains leading landslides, lightening/thunderstorms, Extreme temperatures leading to frost Dry spells leading to wild fires, Strong winds leading to destructions. Fog leads to highway accidents 5

6 Hazards in Kenya Weather hazards have had adverse effects on most communities in Kenya The Arid and Semi-arid Lands (ASALs) are prone to harsh weather conditions Drought is the most prevalent natural hazard in Kenya affecting mainly Eastern, North Eastern, parts of Rift Valley and coast Provinces. Floods seasonally affect various parts of the country especially along the flood plains in the Lake Victoria basin and in Tana river while landslides are experienced during the long rains season running from March to May especially in Murang’a district and areas surrounding the Mount Kenya region. 6

7 Kenya Hazard Map (UNDP PROJECT 2004) 7

8 Common hazards in prone areas Drought prone provinces Eastern, North Eastern, coast, parts of Rift Valley Flood prone areas Budalangi, Nyando, Rachuonyo, Tanariver Landslide prone zones Muranga district, parts of Kiambu, Thika, Maragua, Nyeri, Kirinyaga, Nyandarua and areas around mount Kenya region. 8

9 Recent events In the recent past these hazards have increased in number, frequency and complexity. El Nino rains ( ) had profoundly negative implications on the economy of Kenya and the livelihoods of its population Very heavy rainfall was recorded over most parts of the country in April 2012 and the beginning of May 2012, this resulted into flooding, landslides and land subsiding in the R. Valley causing huge galley like opening on the land surface 9
