Since 1980 plague has been a human threat in the Western Usambara Mountains in Tanzania. However, the spatial-temporal pattern of plague occurrence remains poorly understood. The main objective of this study was to gain understanding of human activity patterns in relation to spatial distribution of fleas in Lushoto District. Data were collected in three landscapes differing in plague incidence. Field survey coupled with Geographic Information System (GIS) and physical sample collections were used to collect data in wet (April to June 2012) and dry (August to October 2012) seasons. Data analysis was done using GIS, one-way ANOVA and nonparametric statistical tools. The degree of spatial cooccurrence of potential disease vectors (fleas) and humans in Lushoto focus differs significantly (p ≤ 0.05) among the selected landscapes, and in both seasons. This trend gives a coarse indication of the possible association of the plague outbreaks and the human frequencies of contacting environments with fleas. The study suggests that plague surveillance and control programmes at landscape scale should consider the existence of plague vector contagion risk gradient from high to low incidence landscapes due to human presence and intensity of activities.
Kilombero cluster development framework (KCDF) In-depth value chain analysis
(FORCONSULT & BACAS CONSORTIUM- Sokoine University of Agriculture, Morogoro, 2023-07) Munishi, P. K. T.; Kashaigili, J. J.; Abdallah, J.; Kadigi, R. M. J.; Mutabazi, K.; Hieronimo, P.; Chunga, C.
The report presents an in-depth analysis of prioritized value chains with the Kilombero Cluster. The analysis maps the core functions of the value chain the key value chain actors, business service providers and supportive stakeholders for value chains development. An in-depth analysis of the value chains overlays key performance measures including volume of transactions, costs and revenue. The analysis establishes trends and development futures of the value chains in terms of demand shaped by mega-trends such as population, income, urbanization and climate change. The report presents the dynamics of the value chains, investment opportunities, and green growth opportunities and constraints. It further explores policy and planning spaces available and reforms for addressing the critical value constraints.
Lepus conference soils, land use and plague Lushoto, Tanzania
(Sokoine University of Agriculture, 2013-08) Hieronimo, P.; Meliyo, J.; Gulinck, H.; Kimaro, D.; Msanya, B.; Mulungu, L.; Kihupi, N.; Deckers, S.; Leirs, H.; Leirs, H.
This excursion guide leads you to the case study area of the LEPUS project. The study area is located in a 200 km2 section of the Western Usambara Mountains and within the Lushoto district (map 1 ). I t is centred over the region in which during the period 1 980 - 2004 many bubonic plague cases were registered. Within the case area, there is west-east gradient from high to low plague incidence.

Variability of soil organic carbon with landforms and land use in the Usambara Mountains of Tanzania
(Journal of Soil Science and Environmental Management, 2016-09) Meliyo, J. L.; Msanya, B. M.; Kimaro, D. N.; Massawe, B. H. J.; Hieronimo, P.; Mulungu, L. S.; Deckers, J.; Gulinck, H.
This study was carried out to assist in the formulation of conservation technologies for landscape sustained productivity in the Usambara Mountains, Tanzania. Conventional soil survey methods were used to develop a base map on which 55 soil profile pits were randomly located on representative landforms and land use mapping units. Soil samples were collected from topsoils for soil carbon analysis using the wet digestion method. Descriptive statistics and linear regression models were used to establish relationships between landforms, land use and soil organic carbon levels. Results showed that carbon levels ranged between 0.55 and 10.8% for bush land and forest plantations in the plain and plateau, respectively. Under cultivation, soil organic carbon (SOC) levels varied between 1.03 and 6.34% for mid-slopes and lower slopes of the plateau respectively. The average soil organic carbon in the vegetable growing valley bottoms was 4.5% while in the forest plantation was 5.5% with minimum and maximum of 0.8 and 10.8% respectively. Linear regression model analysis indicated that factors influencing variability of SOC apart from land use are: slope form, soil pH, electrical conductivity and CECclay. It was concluded that soil organic matter in the study area is mainly determined by elevation, slope form and type of land use and management. Introduction of soil erosion control measures and incorporation of crop residues to areas where soil organic matter has been depleted were recommended for sustainable crop production.
