Assessment of quasi-formal credit for poverty reduction: a case of women and youth development fund Nachingwea district, Lindi – Tanzania.
(Sokoine University of Agriculture., 2007) Mwailafu, Thomas Edwin Mujemaso
A study on assessment of quasi-formal credit on poverty reduction was carried out in
Nachingwea district focusing on Women and Youths Development Fund (WYDF) as a
case study. The study was prompted by inefficient of income generating activities towards
poverty reduction a part from good environment for micro-credit services. The general
objective of the study was to assess the contribution of quasi-formal credit on poverty
reduction in the study area; specifically the study first, sought to investigate the operational
procedures and performance of WYDF. Secondly, the study examined the target
beneficiaries under WYDF. Thirdly, the study intended to identify factors that influence
credit accessibility by borrowers from WYDF and fourthly, the study examined the
contributions of credit on income and the livelihood of borrowers from WYDF. A cross-
sectional research design was adopted. A structured questionnaire was used to collect
primary data from a sample of 102 respondents obtained through multi stage sampling
technique. SPSS 11.5. was used to analyze the data. Study findings show that there was
inadequate facility in meeting credit needs of women and youths in Nachingwea District.
WYDF programme has limited scope and experienced serious operational inefficiencies.
Lending procedures, conditions and target beneficiaries differ significantly. Findings also
revealed that there is positive impact of credit to household income and livelihood. T-test
indicates that there is significant difference between credit users and non-users in relation
to income levels and value of household assets. The study recommended first that critical
screening of target beneficiaries should be done. Second, Ministries responsible for the
fund should make WYDF operate with minimal dependence on the district council. Third,
credit policy should link the WYDF programme to formal financial institutions.
Analysis of economic efficiency of wildlife law enforcement in Serengeti ecosystem protected areas, Tanzania
(Sokoine University of Agriculture, 2013) Nyanghura,Qambemeda Masala
Poaching is regarded to be a critical threat to conservation of protected areas in Tanzania.
To date efforts to reduce poaching are relied on law enforcement techniques which are
reported to require much resources. Efficiency studies on wildlife law enforcement in the
protected areas are limited. This study analyzed and compared economic efficiency of
wildlife law enforcement using three Decision Making Unit (DMU) of Serengeti National
Park, Ikorongo/Grumeti Game Reserves and Ikona Wildlife Management Area. Three
years (2010-2012) monthly data on wildlife law enforcement inputs and outputs were
collected from key informants and supplemented by secondary data. Structured interview
to 153 randomly selected wildlife law enforcement staff was undertaken to collect socioeconomic
data. Shadow prices for non-marketed inputs were estimated, and market prices
were used for tangible inputs. Input-oriented Data envelopment analysis was used to
estimate economic efficiency under Variable Return to Scale and Constant Return to
Scale assumptions. Results revealed that under BCC model, wildlife law enforcement in
all DMUs were technical efficient. Mean allocative efficiency were 78.5% (SENAPA),
87.9% (IGGR) and 97.3% (IWMA), similar to economic efficiency scores. This implies
that to attain economic efficiency, input usage were to be reduced by 21.5%, 12.1% and
2.7% in that order of the DMUs. Economic inefficiency in CCR model was largely
attributed by technical inefficiency than allocative. A significant negative relationship
between days-off and economic efficiency in both models was observed. Likewise,
positive and negative coefficients of labour under constant and variable return to scales
models in SENAPA and IGGR were respectively observed, implying that increase in
labour improve technical efficiencies in SENAPA and reduce the economic efficiencies in
IGGR. The less inefficient observed under IWMA was attributed to sense of ownership
created and participation, roles on responsibility developed through community-based
wildlife management which resulted to decrease in law enforcement inputs.

Factors influencing the performance of marketing intermediaries in bean marketing in karagwe district, Tanzania
(Sokoine University of Agriculture, 2009) Mushongi Cypridion Cyprian
This study is about the contribution of financial services on Emerging Urban Centres
(EUC). The study was conducted in Mvomero District, Turiani division, in Madizini
Township Authority. The interactions between the Emerging Urban Centre and a
neighbouring village (rural) were used to explain rural urban linkages. These
interactions are manifested through the movement of people, goods and services
between the two places. The objectives of the study were to: i) Identify factors that
influence emergence of urban centres, ii) Evaluate income opportunities in emerging
urban centres, iii) Analyze financial flows between rural and emerging urban areas and
iv) identify saving and credit services in the study area. A sample household survey was
used to collect data in both rural (Kunke village) and EUC (Madizini township). A
purposive and simple random sampling was used to select 150 respondents. Descriptive
statistics which include percentages, frequencies, and cross tabulations were used in the
data analysis. / test statistics were used to compare differences in income between rural
and urban households. The findings indicated that urban residents had better access to
credit services (63%) than the rural residents (45%). Farming was the main source of
household income and livelihood in both urban and rural areas. It is recommended that
the development practitioners should develop policy which will guide provision of
affordable interest rate to customers and give priorities to those who wants to establish
SACCOS in rural areas for the improvement of financial service in both rural and urban
areas. When the financial services are working properly, the farming activitites are more
likely to improve as well.
Tropical rainforest deforestation, biodiversity benefits and sustainable landuse: analysis of economic and ecological aspects related to the Nguru mountains, Tanzania.
(Agricultural University of Norway, 1995) Monela, Gerald C.
Monela, G.C. 1995: Tropical rainforest deforestation, biodiversity benefits and sustainable
landuse: Analysis of economic and ecological aspects related to the Nguru mountains, Tanzania.
Doctor Scientiarum Theses 1995:27, ISSN 0802-3220.
The threat to the rainforest in the Nguru mountains due to landuse problems is serious. Because
of the strong link between agriculture and forest degradation, any attempt to alleviate ecological
problems must to a large extent address agricultural-related landuse problems. The primary
objective of this study is to analyze the possibilities for sustainable integrated management of
land-based resources and ecological conservation in the Nguru mountains in order to improve the
living standard of the people and preserve the tropical rainforest in the area. More specifically,
landuse practices are analyzed and micro-economic analysis is used to evaluate the efficiency in
resource use. Mathematical programming is applied in an empirical case study to examine the
impact on deforestation pressure, of agriculture, population pressure and risk. It is also used to
formulate economically efficient farm plans at household farm level in order to analyze the
potential for improving people’s income and resource use. The study is presented in form of three
reports titled as follows:
Report 1. Rainforest degradation and landuse in the Nguru mountains, Tanzania: Analysis of
socio-economic and ecological aspects.
Report 2. Analysis of the use of tropical rainforest species and evaluation of buffer zones and
other control mechanisms in preserving the tropical rainforest adjacent to Mhonda
village in the Nguru Mountains, Tanzania.
Report 3. Socio-economic analysis of deforestation of tropical rainforests as a consequence of
agriculture productivity, risks and population growth: A case study of Mhonda
village in the Nguru mountains, Tanzania.
Results show that several interrelated factors are main driving forces for landuse problems which
enhance deforestation pressure in the Nguru mountains. These include poverty, growing
population, increased domestic demand, lack of knowledge, and risk. The effect of these factors
is enhanced by market and government failures which are partly influenced by demands external
to the country. These factors must be considered to improve farming practices and landuse,
prevent excessive use of the rainforest, and reduce deforestation pressure and degradation. No
single solution exist for these landuse problems, yet the insights gained through the analysis done
provide information to alleviate the situation.
Climate variability and climate information use for water resources conservation decisions: a case of Kilombero river catchment, Tanzania
(Sokoine University of Agriculture, 2018) Moirana, Emanuel Lorivi
This study assessed climate variability and the use of weather and climate information for
water resources conservation decisions in the Kilombero River catchment. In addition, it
assessed the extent of climate change adaptation strategies in the National Water Policy of
2002. Data were collected from 120 household respondents, three focus group and seven
key informants in the three study villages. Historical rainfall and temperature data were
also obtained from the Tanzania Meteorological Agency to discern climate variability in
the area. The rainfall and temperature data were analysed for trends using Mann-Kendall
test. Quantitative data were analysed using Statistical Package for Social Sciences while
qualitative information was analysed using content analysis. Tobit regression model was
used to established factors which influence use of weather and climate information.
Results show inter-annual and seasonal rainfalls do not show consistence increasing or
decreasing trends in Mahenge, Kilombero and Ifakara stations for the period 1986 - 2016.
However, annual and intermediate (January and February) rainfalls in Mahenge showed
decreasing trends significant at 0.05 a level of significance. Temperatures were increasing
at Mahenge station for all seasons, but significant trends were observed in annual
minimum and minimum temperatures during short rains (October, November and
December) at 0.05 and 0.01 a levels of significance respectively. Weather and climate
information are locally available in the area with medium use. Extension visits (13=0.079;
p<0.01), scientific types (13=0.182; p<0.05), traditional methods (13=0.114; p<0.05) and
household income (13=0.072; p<0.05) were the only factors which had significant and
positive correlations with decisions on water resources conservation. It is concluded that
climate is highly variable and there is medium use of weather and climate information.
The study recommends improvements of communities’ adaptive capacity emphasize
factors which had significant positive correlations with decisions on water resources
conservation.
