Abstract
Lake Rukwa valley is endowed with various natural resource such as wetland, Lake
Rukwa, Ilemba and, Mbizi forest reserve, Rukwa and Uwanda game reserve with
abundant helium gas which has been recently discovered. Presence of these natural
resource leads to a number of challenging factors which underpin sustainable
management and utilization of natural resources. The objective of this study was to
identify land-use cover practice and socio-economic activities, to analyse the land-cover
changes (LCC) and to determine the influence of LULCC on the socio-economic
activities in Lake Rukwa Valley. Random sampling was employed in this study by
interviewing 30 households in each village of the four chosen villages of Ilanga, Mtowisa
B, Kisa and Ilemba B. Sampling frame were drawn from village book registry, key
informant, focus group discussion and interviews with governments official and village
leaders. Data were collected using semi-structured questionnaire with an open-ended
question while land-use and land-cover changes were determined using satellite imagery
for the two epoch of 1995 to 2020 years. The imagery downloaded were analyzed using
computer Arc View program with a combination of GIS programs while socio-economic
data associated with LULCC were analyzed using descriptive statistics was applied to
obtain frequencies and percentages, then cross-tabulation was performed, chi-square test
was used to determine the significance level between the data obtained and the trend of
land use and land cover changes in Lake Rukwa Valley. The results revealed that there is
significant changes in land-use classes at a study area as p <0.05, therefore study
concluded that there is a long term association between land-use and land-cover changes
in Lake Rukwa Valley. Thus the study recommended that, there is a need of policy
makers, district land planner’s to take measure in maintaining sustainable resource
utilization to minimize and maintain land cover changes in Lake Rukwa Valley.
