Air Pollution Monitoring System based on Wireless Networks - Simulation
(Innovative Systems Design and Engineering, 2014)Air pollution is one of environmental issues that cannot be ignored. Industrial growth and urbanization results in the air pollutants concentrations in many areas. These pollutants can cause damages in human health and ... -
Assessing protected area effectiveness in western Tanzania: Insights from repeated line transect surveys
(wiley, 2023-08-07)In many parts of East Africa, wildlife populations have declined over the past decades. Given these trends, site-based studies are needed to assess how protected areas with differing management strategies enable the effective ... -
An overview of pipeline leak detection and location systems
(Pan African International Conference on Information Science, Computing and Telecommunications, 2014-07)Leak detection in transmission pipelines is crucially important for safe operation. Delay in detecting leaks leads to loss of property and human life in fire hazards and loss of valuable material. Leaking of methane and ... -
Modelling elephant corridors over two decades reveals opportunities for conserving connectivity across a large protected area network
(PLOS ONE, 2023-10-13)Protected area (PA) connectivity is pivotal for the persistence of wide-ranging wildlife species, but is challenged by habitat loss and fragmentation. We analyzed habitat suitability and connectivity for the African elephant ... -
Invasive weeds with pesticidal properties as potential new crops
(Elsevier, 2017)Plants with pesticidal properties have been investigated for decades as alternatives to synthetics, but only a handful have been commercialised and developed as non-food cash crops. One of the reasons why pesticidal plants ... -
Climate change impacts outweigh conservation efforts in coral reefs that are highly exposed to thermal stresses in Zanzibar, Tanzania
(Elsevier, 2023-05-01)With a greater range of management practices and so many threats to coral reefs, assessing coral reef resilience using social-ecological approaches is an important way towards understanding the climatic and non-climatic ... -
Optimization of goat manure against use of N-Minjingu Nafaka Plus fertilizer for improved lablab growth and yield in semi - arid areas of Northern Tanzania
(Elsevier, 2023-12)The study was conducted in Northern Tanzania from the 2022–2023 cropping seasons to develop a cropping model that farmers can use to improve their lablab production. The field experiments were conducted at the Tanzania ... -
Biological control interventions and botanical pesticides for insect pests of crops in sub-Saharan Africa: A mapping review
(Frontiers in Sustainable Food Systems, 2022-07-28)Agricultural productivity can be increased sustainably in sub-Saharan Africa (SSA) by reducing crop losses due to insect pest damage. As an alternative to environmentally-damaging chemical pesticides, biological control ... -
Biological control interventions reduce pest abundance and crop damage while maintaining natural enemies in sub-Saharan Africa: a meta-analysis
(The Royal Society, 2022-12-07)Insect pests are a major challenge to smallholder crop production in sub-Saharan Africa (SSA), where access to synthetic pesticides, which are linked to environmental and health risks, is often limited. Biological control ... -
Heritability and relationship between drought tolerance traits and yield in groundnuts (arachis hypogaea l.) under different watering regimes
(Asian J Agri Biol,, 2016)Improvement of groundnuts for drought tolerance could increase production in drought prone areas.This study aimed at determining the heritability estimates and relationship of HI and SCMR with yield and yield components ... -
Advances and trends in ecological organic agriculture (EOA) technologies and research on fruit vegetables produced in Tanzania
(CABI, 2022-07-15)Ecological organic agriculture (EOA) is a holistic production management system that can solve many problems in the vegetable crops’ value chain (VC). It is, however, unclear about the EOA technologies for the fruit vegetable ... -
Characterization of Provitamin A Status and Distribution in Commercial Grown Maize Varieties in Tanzania
(East African Journal of Science, Technology and Innovation, 2022-02-16)Provitamin A carotenoids are important as precursors for vitamin A, essential for stronger immune system and eyesight. Consumption of a plant-based diet rich in provitamin A such as provitamin A maize is an easy and ... -
Caudal fin as a proxy for dorsal muscle for nutrient enrichment monitoring using stable isotope analysis: the case of Gerres filamentosus and G. oyena from mangrove creeks of Tanzania
(Western Indian Ocean Journal of Marine Science, 2022)The use of fish dorsal muscles in stable isotope studies, which is an invasive method that results in fish deaths, limits their applicability for rare and endangered fish species, as well as when large sample sizes and ... -
Influence of farmers’ socio- economic characteristics on nutrient flow and implications for system sustainability in smallholdings: a review
(Frontiers in social science, 2023-04-14)The rise in global human population, coupled with the effects of climate change, has increased the demand for arable land. Soil fertility has been the most affected, among other things. Many approaches to soil fertility ... -
Breeding potential of lablab [Lablab purpureus (L.) Sweet]: a review on characterization and bruchid studies towards improved production and utilization in Africa
(Springer Netherlands, 2021-09-22)Lablab (Lablab purpureus) [Lablab purpureus (L.) Sweet] is termed a lost, underutilized and neglected crop in Africa. Despite the multipurpose use, production, consumption and research are still limited. Wide genetic ... -
Using fishers’ local ecological knowledge for management of small-scale fisheries in data-poor regions: Comparing seasonal interview and field observation records in East Africa
(Elsevier, 2023-08)Fishers, scientists and policy makers need to describe, understand and “agree on” variations in fish catches caused by exploitation and climate change for effective fisheries management. To achieve this, relevant data with ... -
Ecological Changes in the Zambezi River Basin
(African Books Collective, 2021-11)Africa faces a plethora of challenges and chief among these is a change in the climate (Zakaria and Maharjan 2014) which is one of the key factors affecting the ecology and hydrology of its river basins (Kusangaya et al. ... -
Maize stover transfers from maize fields to banana-based agroforestry homegardens and the corresponding nutrient flows in central-northern Tanzania
(Frontiers in Forests and Global Change, 2023-07-13)Maize (Zea mays) stover produced in the drier lowland areas on the volcanic foot slopes of Mount Kilimanjaro serves as an important additional fodder for smallholder zero-grazed dairy cattle farming in the humid highland ... -
