The study focused on identifying agronomic practices and assessing their impacts on agro-ecosystems’ resilience; examine the socio- economic status of the farmers in the region and its impacts on agro-ecosystems; and examine the agro-ecosystems’ natural resilience and assess social-ecological vulnerability index to the impacts of climate change. About 400 households was covered in this household survey with response rate of 97% where by farmers were asked on their farming practices and systems, key informants and transect walk was also employed in gathering necessary information. Study was carried out at a specific designed transect for a selected part of Kilimanjaro region between Kisangesangeni-Miwaleni (700 m.a.s.l) and Makunduchi/Kirua Vunjo (1600 m.a.s.l) of about 21.7 km long at the southern part of Mount Kilimanjaro in Moshi rural district. The study shows a significant variation in agronomic practices with altitude and lack of sufficient agro-ecosystem resilience framing like conservation agriculture including agro-forestry, conservation tillage, contouring and terracing, mulching, Mix- intercropping, and fallowing to mention a few; pest and disease control, soil conservation infrastructure, and off farm diversification were also key challenge to farmers. Social-ecological and economic Parameters was used in computation of vulnerability index. Because of variation in altitude which associates with different in microclimate and soils, the vulnerability also varied with altitude. Elements like household cooking energy (94.8%), agriculture as main source of household income (94.5%), off farm contribution to the household (34%) etc. has shown to have some implication on household on choosing alternatives options on adaptations. v TABLE CONTENTS CERTIFICATION .......................................................................................................................... i DECLARATION AND COPYRIGHT ........................................................................................... ii ACKNOWLEDGEMENT ............................................................................................................. iii ABSTRACT ................................................................................................................................... iv TABLE CONTENTS ...................................................................................................................... v LIST OF FIGURES ..................................................................................................................... viii LIST OF PLATES ...........................................................................

    CLASSIFICATION OF CHAGGA AGROFORESTRY HOMEGARDENS AND THEIR CONTRIBUTIONS TO FOOD, INCOME AND WOOD ENERGY TO COMMUNITIES OF ROMBO DISTRICT, TANZANIA JIMSON MBWIGA A DISSSERTATION SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE IN MANAGEMENT OF NATURAL RESOURCES FOR SUSTAINABLE AGRICULTURE OF SOKOINE UNIVER SITY OF AGRICULTURE. MOROGORO, TANZANIA. 2016 ii ABSTRACT The present study was carried out in 2014 in Rombo District, Kilimanjaro, Tanzania, in order to classify Chagga agroforestry homegardens and establish their relative contributions to food, income and wood energy to the local communities. The study methodology included random selection of four divisions, one ward from each division, one village from each ward and 30 households per village forming a total sample of 120 households. A social survey was subsequently carried out using questionnaires employed to household heads and checklists of probe questions for key informants. Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 16.0 and Microsoft Excel Programs. Analysis of Variance (ANOVA) was performed to compare means between and within treatments and the Least Significant Difference (LSD) was used to separate the significantly differing means. Results indicated that all five renewable natural resource components of woody perennials, herbaceous crops, animals, insects and aquatic life-forms were present in the Chagga agroforestry homegardens which were in various interactions broadly classified into nine agroforestry systems with the Agrosilvopastoral system being the most widely spread and the Agroaquosilvicultural, Agroaquosilvopastoral, Aposilvopastoral and Silvopastoral systems being, in that order, the least spread throughout the district. Spatial arrangements of components were the most common arrangement forming agroforestry technologies like boundary planting, mixed intercropping and live fences.

  • The Economic Efficiency and Effectiveness of Domestic
    THE ECONOMIC EFFICIENCY AND EFFECTIVENESS OF DOMESTIC WATER ALLOCATION IN MOSHI RURAL DISTRICT: THE CASE OF KIRUA-KAHE META, PETER ONESMO A DISSERTATION SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE IN ENVIRONMENTAL AND NATURAL RESOURCE ECONOMICS OF SOKOINE UNIVERSITY OF AGRICULTURE. MOROGORO, TANZANIA. 2016 ii ABSTRACT Water is one of the scarce resources very important for the development for humankind hence efficient allocation is needed. Economically, efficient allocation of water is desirable to maximize the welfare of the society that obtains from available sources. The rural population water supply services have been left behind which increase with domestic water demand. There are some initiatives in Moshi Rural District to establish some water projects so as to solve the problem of water scarcity. There was a need to know the efficiency of domestic water allocation for the case of Kirua-Kahe because relatively little is known about the service and satisfaction of customers. There are three specific objectives in this study which are to evaluate the domestic water allocation of Kirua-Kahe Water Project in Moshi Rural District, to determine the domestic water allocation efficiency in Kirua-Kahe Water Project and to examine the effectiveness of Kirua-Kahe domestic water allocation in Moshi Rural District. Cross section or survey design was used with both quantitative supplemented with qualitative approach to present results. Methods for data collection involved primary and secondary sources through interviews, questionnaires and direct observations. Findings show that Kirua-Kahe uses Gravity and Pumping systems for supplying water. Gravity water supply system has 8 working intakes, 2 boreholes while Pumping water Supply system consists of 15 small pumping schemes being pumped from boreholes and 1 spring.

So- cio-economic survey design was used and both qualitative and quantitative research approaches was employed. Data were collected using questionnaires survey, key informant interviews, focus group discussions as well as field observation. A total of 96 farmers were involved in the study. The Statistical Package for Social Sciences (SPSS) was used to analyse the data. The data were presented in condensed form in terms of tables, and fig- ures.The findings revealed that communities were knowledgeable about the effects of climate variability. Their knowledge was based on the effects already felt and attributed to climate variability, including unpredictable patterns of rainy seasons. Climate variability was associated with decrease in cash crop production and increase in household food supply, unpredictable farming calendar including drying of water sources used for irrigation and domestic uses. The findings revealed a decreasing trend of Coffee yields during the year 1990 to 2016. The decreasing trend of coffee production in the area was not only contributed by climate change variability but also fall of coffee price in the world market. The communities in the study area developed different adaptation strat- egies in responding to effects of climate variability.

  • The Use of Nominal Group Technique in Identifying Community Health Priorities in Moshi Rural District, Northern Tanzania
    133 Tanzania Health Research Bulletin 7, September 2005 The use of nominal group technique in identifying community health priorities in Moshi rural district, northern Tanzania E.A. MAKUNDI1*, R.

Box 9653, Dar es Salaam, Tanzania 2Kilimanjaro Christian Medical Centre College, Tumaini University, Moshi, Tanzania 3Centre for Medical Parasitology, University of Copenhagen, Denmark ______________________________________________________________________________ Abstract: This article highlights issues pertaining to identification of community health priorities in a resource poor setting. Community involvement is discussed by drawing experience of involving lay people in identifying priorities in health care through the use of Nominal Group Technique. The identified health problems are compared using four selected village communities of Moshi district in Kilimanjaro region, Tanzania. We conducted this study to trace the experience and knowledge of lay people as a supplement to using 'health experts' in priority setting using malaria as a tracer condition. The patients/caregivers, women's group representatives, youth leaders, religious leaders and community leaders/elders constituted the principal subjects. Emphasis was on providing qualitative data, which are of vital consideration in multi-disciplinary oriented studies, and not on quantitative information from larger samples. We found a high level of agreement across groups, that malaria remains the leading health problem in Moshi rural district in Tanzania both in the highland and lowland areas. Our findings also indicate that 'non-medical' issues including lack of water, hunger and poverty heralded priority in the list implying that priorities should not only be focused on diseases, but should also include health services and social cultural issues.
