(Climate Research in Africa, 2022)This is a review of policies, strategies, and frameworks related to climate change, agriculture, food, and nutrition security in Ethiopia, Kenya, Rwanda, Tanzania, and Uganda. The five focus countries have made tremendous ... -
Soil Mineral Status, Plant Ionome and Agro-Morphological Traits of Schkuhria Pinnata (L.), An Antimalarial Herb: Implications for Cultivation
(East African Science, 2022)Background: Schkuhria pinnata L., is an antimalarial plant that is highly threatened by the destructive harvesting methods and its collection largely relies on wild sources, that are also exposed to over-exploitation and ... -
The Physico-Chemical Quality of Streams and Channels Draining into River Rwizi, South Western Uganda.
(Journal of Water Resource and Protection,, 2018-09-04)There is an increased human population along the catchment area of river Rwizi who are engaged in various activities with potential to contaminate river Rwizi especially along the streams. Studies have been done to ... -
Speciation in Ancient Lakes 8 – Celebrating 25 years and moving towards the future
(Journal of Great Lakes Research, 2020)Hypotheses in evolutionary biology, ecology, climatology and geology are often tested in insular ecosystems. Ancient lakes, i.e. lakes that have existed since at least the Last Glacial Maximum and typically for longer ... -
Harnessing the nutritional benefits of pineapple pulp fiber to enhance antioxidant potential of wheat flour
(Research square, 2022)Pineapple pulp fiber is highly palatable but is usually wasted during the processing of pineapple juice resulting in a loss in the pineapple value chain. It is known to contain both soluble and insoluble dietary fiber, ... -
Nutritional and anti-nutritional physicochemical composition of cocoyam accessions grown under upland conditions
(Makerere University Journal of Agricultural and Environmental Sciences, 2020)Cocoyam (Colocasia esculenta (L.) Schott) is commonly grown in wetlands, which are ecologically fragile ecosystems that should be conserved. The objective of this study, therefore, was to evaluate the effect of growing ... -
Population Structure and Regeneration Status of Trichilia dregeana Sond. in Heavily and Less Disturbed Areas of Kalinzu Forest Reserve, South Western Uganda
(Open Journal of Forestry,, 2015)The population structure and regeneration status of Trichilia dregeana in heavily and less disturbed habitats of Kalinzu forest reserve were assessed in 2013. The species was used locally for medicines, fire wood and ... -
Can citizen scientists provide a reliable geo-hydrological hazard inventory? An analysis of biases, sensitivity and precision for the Rwenzori Mountains, Uganda
(Environmental Research Letters, 2022)Spatio-temporal inventory of natural hazards is a challenging task especially in rural or remote areas in the Global South where data collection at regional scale is difficult. Citizen science, i.e. involvement of no-experts ... -
Causes of losses and the economic loss estimates at post-harvest handling points along the beef value chain in Uganda
(Journal of Agricultural Extension and Rural Development, 2019-10)Uganda’s beef industry has been growing slowly and requires sustained monitoring of actors at post harvest handling points in order to decrease public health risks and losses. This study documented causes of losses and ... -
Nutritional physico-chemical composition of pumpkin pulp for value addition: Case of selected cultivars grown in Uganda
(African Journal of Food Science, 2020-09)Pumpkin is one of the underutilized fruit-vegetables in Uganda although it is one of the crops believed to have carotenoids with pro-vitamin A activity that are not common to many other crops. While other crops are being ... -
Evaluation of faecal analysis as an indirect method for determination of chimpanzee dietary composition
(Journal of Agricultural and Environmental Sciences, 2020)The study used 2,635 chimpanzee (Pan troglodytes schweinfurthii) faecal samples and each sample was analysed while wet, and after drying. The two methods used in this analysis were proportional (5%) scores and volume ... -
The Future of Tropical Water Resources: Using Palaeolimnology to Inform Sustainable Management.
(2000)Lakes are an important resource. They provide vital ecosystem services and employment for many communities worldwide. Maintaining lakes as ecosystem providers without damaging the lake ecosystems themselves, against a ... -
Recasting the Sangoan Stone Age Techno-Complex in the Stone Age Nomenclature at Sango Bay, Southern Uganda
(Studies in the African Past, 2022)This paper discusses the complex use of the term ‘Sangoan’ and its placement between the Early Stone Age (ESA) and Middle Stone Age (MSA) using data from Simba Hill in Sango Bay. The purpose is to examine whether the Sangoan ... -
Land use and land cover change influence on soil organic carbon content for a pastoral area: use of geographical information system
(East African Journal of Science, Technology and Innovation, 2022)Data on land use and cover change and soil organic carbon (SOC) in rangelands are essential. This is because rangelands ecosystems are fragile, and poor land-use practices can significantly threaten their sustainability ... -
The Challenges of Reconstructing Tropical Biodiversity With Sedimentary Ancient DNA: A 2200-Year-Long Metagenomic Record From Bwindi Impenetrable Forest, Uganda
(Frontiers in Ecology and Evolution, 2020-07-10)Sedimentary ancient DNA has been proposed as a key methodology for reconstructing biodiversity over time. Yet, despite the concentration of Earth’s biodiversity in the tropics, this method has rarely been applied in this ... -
Minerals in the Foods Eaten by Mountain Gorillas (Gorilla beringei)
(PLoS ONE, 2014)Minerals are critical to an individual’s health and fitness, and yet little is known about mineral nutrition and requirements in free-ranging primates. We estimated the mineral content of foods consumed by mountain gorillas ... -
Historical Perspectives of Land Use and Land Cover Change in the Sanga-Lake Mburo former Pastoral Rangeland Ecosystem, Uganda
(International Journal of Environment and Geoinformatics, 2022)Socioeconomic, political, and policy decisions by the government may influence the socioecological changes of the land use and land cover pattern for rangeland people over time. This paper examines the historical political, ... -
High Altitude Diets: Implications for the Feeding and Nutritional Ecology of Mountain Gorillas
(In High altitude primates, 2014)Though the majority of primates live in tropical habitats, several species partially or exclusively range in high altitude regions of Africa, Asia, and Madagascar (Blanco and Rahalinarivo 2010; Iwamoto and Dunbar 1983; ... -
A comparison of two mountain gorilla habitats in Bwindi Impenetrable National Park, Uganda
(African Journal of Ecology, 2004-12)Bwindi Impenetrable National Park, Uganda, is a small protected area (331 km2) within which there is large climatic and altitudinal variation. Therefore we compared habitat types and forest composition between two locations ... -
