Landslides were expected and warnings given through the Media-TV, radio, print

All relevant Government departments were informed – Ministry of Water and Environment , Department of Disaster management, Ministry of Agriculture, Health etc

Various TV, radio and Print media houses continued to get updates from the Department on phone or came physically.

However, a landslide that occurred still had devastating effects.

2010 Landslide in 2010 Landslide in BududaBududaBududa District is found in the

Eastern Region part of Uganda about 365 kilometres from the capital city, Kampala.

LOCATION OF BUDUDA LOCATION OF BUDUDA DISTRICTDISTRICT

Physical backgroundPhysical background

The district lies at an average altitude of 1,800 metres (5,900 ft) above sea level on the slopes of Mt. Elgon, a dormant Pliocene shield (mid-plate) volcano on the border of Uganda and Kenya.

ClimateClimateMt Elgon has a bimodal rainfall

pattern with no dry season and with an annual mean between 1,500-1,800 mm.

Population densityPopulation densityAccording to the 2002 census

Bududa has an average population density of more than 1300 persons km2. This rapidly increasing density implies there is land scarcity in the district where subsistence agriculture is the main land use. Land parcels are therefore small (approximately 35 m2) and even unstable slopes, often steeper than 80% are cultivated.

LandslidesLandslides

Landslides are therefore common in the districts of Mt. Elgon. These districts include Bududa, Sironko, Mbale, Manafwa, Kapchorwa and Bukwo.

Landslide of 1Landslide of 1stst March March 20102010On the night of Monday 1st March 2010 a

massive landslide struck Nametsi village in Bududa District.

The tragedy followed a heavy seven-hour downpour which started falling at about midday.

This was the largest and most catastrophic landslide on the Mount Elgon.

Causes of the landslideCauses of the landslide

Causes of the landslideCauses of the landslideHowever, deforestation may have also played a role.

Deforested mountains are very prone to landslides because there is a lot of loose material- namely soil and rocks.

 On a steep slope, trees anchor the soil.

Causes of the landslideCauses of the landslideSources from the Uganda Wildlife

Authority (UWA), also pointed out that the affected area was technically inside Mt. Elgon National Park, a protected area, but had been encroached, with villagers felling trees and cultivating on steep slopes since 2007, which may have been a contributing factor for the immense scale of the tragedy.

Effects of the LandslideEffects of the LandslideOver 300 people confirmed dead . The missing reportedly also include about 100 school children who had taken shelter in one of the villages from the torrential downpour and who were swept away by the mass of water, mud and rocks coming down the mountainside.

Effects of the LandslideEffects of the LandslideThree villages in total were wiped

out in the location, known as Bukalasi subcounty with Nametsi being the hardest hit. The Red Cross said two other villages of Namakansa and Kubewo were also affected.

Effects of the LandslideEffects of the Landslide

About eighteen of the dead were recovered from River Manafwa about 26 kilometres from where the disaster struck.

It is estimated that nearly 50,000 people, some occupying the immediate precincts of the extinct volcano, are regularly exposed to the threat from landslides.

What next ?

Other effects of the Other effects of the landslide landslide Butaleja district was particularly

affected by floods because it is a low-lying area through which water from the Mt. Elgon region drains.

 According to experts the problem is

compounded by the fact that Butaleja has many rivers which have burst their banks due to the large volumes of water driven to the area by River Manafwa.

Floods in ButalejaFloods in ButalejaNawangofu, Budumba, Busabi,

Maizimasa Namutu and Kachonga were the hardest-hit sub-counties, rendering 37,000 people homeless, .

The torrential rains of the end of February and beginning of March 2010 have washed away latrines and made mud and wattle houses collapse.

Effect on Education:Effect on Education: At least four schools in Butaleja

were closed due to flooding of classrooms and latrines.

Over 2,000 pupils at Doho, Namalere, Lubembe and Bugombe primary schools were faced with a double tragedy-they were homeless and could not attend classes.
