The work was commissioned by The Ministry of Water, Nairobi, Kenya and Massachusetts Institute of Technology, USA. The project has been carried out as a Minor Field Study in Nairobi and Nakuru, Kenya during the period January – April 2005 and was completed in May –June in Luleå, Sweden. The field work was performed in Baringo District in the northern part of Rift Valley Province. This project has throughout the time continuously undergone changes. Changes in form of object, area, time, supervisors, organizations and people involved. The time in Kenya has been challenging but also very profitable and we are grateful that we got the opportunity to work in this interesting country. Despite that the project developed in a slightly different way from what we planned for in the beginning we hope that the result of this study will benefit the people of Kenya and be useful for the involved organizations. While working with this project we met and were introduced to many people. First of all we would like to send a great Thank You to our Professor, Jörgen Hanæus, at Luleå University of Technology for helping us with advice from Sweden. Also thanks for contacting and introducing us to Susan Murcott at Massachusetts Institute of Technology in the U.S. We would also like to thank the employees at the GIT (Geographic Information Technology) department in Luleå, especially Fredrik Salén, for the great support and supervising after we came back from Kenya. For all help and support in Kenya we would like to thank Susan Murcott at MIT, Peter Jacobsen and the rest of the people at Catholic Diocese of Nakuru Water Programme. You really made our visit pleasant and enjoyable. Without you we would still be struggling with inadequate information. Last but not least, we would like to thank the Swedish International Development and Cooperation Agency (SIDA) and Internationella Programkontoret for providing the main financial funding. To all the helpful people of Kenya that we met along the road: Asante Sana, you will not be forgotten! Luleå - Sweden, June 2005 Jörgen Näslund Ingemar Snell II Jörgen Näslund – Ingemar Snell GIS-mapping of Fluoride Contaminated Groundwater in Nakuru & Baringo district, Kenya A Minor Field Study ABSTRACT This Master of Science thesis has been carried out in Nakuru and Baringo Districts in the Rift Valley Province in Kenya. The thesis was performed as a Minor Field Study (MFS) financed by the Swedish International Development and Cooperation Agency (SIDA), through the “Internationella Programkontoret”. High fluoride levels in the ground water are a major problem that leads to diseases related to a high fluoride intake amongst people. In the Rift Valley Province, Kenya the bedrock consists of fluoride bearing minerals which contaminate the water. High levels are more common in deeply drilled boreholes than in surface water. Catholic Dioceses of Nakuru (CDN) is a non – governmental organization stationed in Nakuru working with defluoridation methods to remove fluoride from drinking water. In 1985 they started a Water Programme with extensive activity within water supply and quality. In their continuous work a GIS- map over fluoride levels in boreholes would be useful. This thesis summarizes the work with creating a GIS –map. The map shows location and 6 other parameters of interest from 195 boreholes drilled by CDN. Except from the work with the GIS –map this report also summarize results from a field study in an area around Lake Baringo in Baringo District. The aim with the field study was to investigate and overview the water situation. All in all 52 water sources were found, 7 permanent and 45 seasonal. The results and conclusions from the field study are presented in this report. They will hopefully facilitate the decision-making process for CDN. A CD with data files concerning the GIS-map can be received from Division of Sanitary Engineering at Luleå University of Technology.

    REPUBLIC OF KENYA BARINGO COUNTY GOVERNMENT ANNUAL DEVELOPMENT PLAN 2016/17 County Treasury and Economic Planning AUGUST 2015 Annual Development Plan-2016-2017 i FOREWORD The 2016/2017 Baringo County Annual Development Plan (ADP) is formulated in the model of the current Medium Term Expenditure Framework (MTEF). The Plan is prepared in line with the requirements of Section 126 of the Public Finance Management Act 2012, and in accordance with Article 220(2) of the Constitution. The Annual Plan contains the strategic priority development programmes and projects that will be implemented during the financial year 2016/2017. The Budget preparation process in the Medium Term, adopted the Programme Based Budgeting approach, where the sector working groups in the county formulated their respective sectors’ budget proposals, policies and programmes with clear outputs, outcomes as well as performance indicators which are related to the achievement of the programme objectives. This annual plan is therefore framed against a broad fiscal policy and reform measures underpinning the budget for the 2016/17 Financial Year, which outlines expenditure per priority programmes as well as allocation of resources to all sectors of the County economy. Significant proportion of the County’s budget shall be financed through National Government funding while it is expected that the County Government and development partners shall bridge the gaps. The preparation of the annual plan made reference to key County and National Government Policy documents particularly the Baringo County Integrated Development Plan (2013– 2017), the Second Medium Term Plan (2013 – 2017) and Vision 2030, the approved County Programme Based and Budget (PBB) 2015/2016.

  • The East Pokot Pastoralists in Conflict Siege: Reflections on Cultural Interpretations of Persistent Conflict
    International Journal of Education and Research Vol. 1 No. 10 October 2013 The East Pokot Pastoralists in conflict siege: Reflections on cultural interpretations of persistent conflict Dr. Beneah Manyuru Mutsotso * * Department of Sociology and Social Work, University of Nairobi. P.O B.o.x 30197 00100 Nairobi. Kenya Email address [email protected]/ [email protected] Tel contact: +254 722833012 Abstract The East Pokot pastoralists are part of the Nilotic group that belong to the Karamoja cluster. They are found in Baringo County of North Western Kenya. They neighbor the Turkana, Samburu, Il Chamus (Njemps), Tugen and Marakwet. They always have had an acrimonious relationship with the Kenya government from the colonial period to the present.All through they have a conflictuous relationship with all the neighbouring pastoralist and agro pastoral communities over livestock and lately territory. This paper suggests that the intensity, scale and frequency of conflict has continued unabated in the face of government and other actors interventions through a combination of threat of force and/ or negotiated settlement. This paper, based on primary and secondary data, argues that the motivators of conflict from the perspective of the East Pokot are historically and culturally defined. While there exist specific cultural interpretations in relation to each community the overall cultural interpretations for conflict are presented as: revival of the sharpening stone, misbehavior and carelessness by the middle age group which has angered Tororot (God). 1.1 Background 1.2 Introduction Ever since the path breaking study by Fukui and Turton (1979) titled Warfare among East African herders, the question of conflict among pastoralists has remained high on the agenda and perspectives to understand the motivations remained elusive.

BOX 53-30400 KABARNET, KENYA SUBMITTED TO: THE DIRECTOR GENERAL, NATIONAL ENVIRONMENT MANAGEMENT AUTHORITY, NAIROBI, KENYA FINAL REPORT FINAL REPORT FINAL JUNE, 2021 i ii EXECUTIVE SUMMARY Mochongoi Settlement Scheme is located in Ol Arabel Forest in Mochongoi Ward, Baringo South Sub County, Baringo County. The scheme was established in the year 1989 by Presidential Directive to resettle people displaced from their lands to create space for government projects including Kirandich dam, schools, churches, the airstrip and the Government Training Institute (GTI). However the due process of the degazettement of the forest for the establishment of the settlement was not undertaken at that time. This led to the development of the informal Mochongoi settlement causing encroachment and land ownership problems. Part of the settlement scheme was degazetted and some land owners were issued with land titles while others have allotment letters (Block I). However majority of people in the settlement scheme do not have land ownership documents. On Tuesday 23rd February 2016, the people of Mochongoi Settlement Scheme petition the National Assembly through their MP Hon. Grace Kipchoim for degazettement of Ol Arabel Forest for Mochongoi Settlement Scheme and issuance of titles pursuant to Article 119 (1) of the Constitution of Kenya (2010) and Standing Order 219.
