Carrot-Weed: A Noxious Plant That Threatens Biodiversity in Africa
(Scientific Research Publishing, 2019-03-20) Mtenga, Neema; Tarimo, Thadeo; Ndakidemi, Patrick; Mbega, Ernest
Carrot-weed ( Parthenium hysterophorous L.) is a flowering plant of the As- teraceae family (tribe: Heliantheae). The weed became famous due to its no- torious invasive role in the environment and agricultural fields. The plant has arisen as the seventh most disturbing weed globally. In Africa, the weed is spreading very fast and information on its biology, impact, and management is scarce. Therefore, this review provides general information about the carrot weed’s current distribution status and its impact on agricultural crops, ani- mals and human health in Africa . The review also highlights areas for re- search in managing this noxious weed in the African habitats.
Decentralized Environmental Governance: A reflection on its role in shaping Wildlife Management Areas in Tanzania
(Tropical Conservation Science, 2015-12-01) Kiwango, Wilhelm; Komakech, Hans; Tarimo, Thadeo; Martz, Lawrence
Decentralised environmental governance has become a catchy solution to environmental problems caused by the failure of traditional centralised environmental governance. It promises to transfer power and authority, improve efficiency, equity, accountability, and inclusion of local people who were previously excluded by the command and control model. This paper examines the efficacy of decentralised environmental governance as an alternative approach to wildlife conservation in Tanzania. We analyse the policy and legal framework for Wildlife Management Areas (WMAs) in Tanzania over the past two decades as a case study on current practice and its implications. We find that despite the rhetoric of community-based conservation (CBC), the wildlife industry remains heavily under state control, while the promises of CBC remain elusive. Questioning the effectiveness of decentralised environmental governance through CBC, we recommend that actors return to the drawing board and re-negotiate their positions, interests, power and authority if meaningfully decentralised environmental governance is to be achieved.
Levels of community participation and satisfaction with decentralized wildlife management in Idodi-Pawaga Wildlife Management Area, Tanzania
(Taylor & Francis online, 2017-09-14) Kiwango, Wilhelm; Komakech, Hans; Tarimo, Thadeo; Martz, Lawrence
Participatory approaches to conservation are viewed as a plausible alternative to the old ‘fortress conservation’ approach. The design and implementation of these approaches in developing countries have tended to embrace community participation through decentralized governance mechanisms in the past three decades. However, sustainable conservation approaches that maintain community livelihoods while conserving biodiversity are challenged with meeting both objectives. In addressing this challenge, little attention has been given to an empirical analysis of community’s satisfaction levels on how they participated in the design and implementation of this approach. In this article, we use a mixed method approach using both quantitative and qualitative data to examine levels of satisfaction and participation of local communities in the Idodi-Pawaga Wildlife Management Area (WMA), south-western Tanzania. We find that social economic factors (e.g. age, household size, gender, number of years living in the same location and participation/non-participation) influence, in different ways, the satisfaction levels of community’s participation towards the WMA creation. Due to inadequate participation, we find that the WMA design and implementation process failed from the beginning to actively involve the local communities and this has resulted in the near absence of the promised economic benefits from wildlife conservation. We suggest that participation should go beyond the simple information sharing to actively engage the local communities in key planning activities from the beginning of any WMA programme. It is also important to take into consideration their levels of satisfaction with the process of decision-making if meaningful decentralized governance is to be achieved.
Status of sucking insect pests in cashew growing locations of South and Central Zones, Tanzania
(International Journal of Biosciences, 2020-04-14) Assenga, Bobnoel; Masawe, Peter; Tarimo, Thadeo; Kapinga, Fortunus; Mbega, Ernest
Cashew (Anacardium occidentale L.) is an economically important cash crop for many rural households in Tanzania. However, its production is constrained by some insect pests and diseases. As a precondition for the development of a more sustainable integrated insect pest management strategy for cashew, information on the incidence and severity of cashew sucking insect pests in a changing environment is required. Field surveys were conducted in the major and minor cashew producing areas of Tanzania in two phases, February to March 2019 during the vegetative season and July to August 2019 during reproduction season. The surveys were conducted in 24 cashew fields in six districts (Liwale, Masasi, Nachingwea, Manyoni, Kongwa and Mpwapwa) in southern and central agricultural research zones in Tanzania. Data on a number of shoots infected by sucking insect pests, i.e. black lesion, leaf damage, dieback level, pest counts and counts of natural enemies were collected from the two zones. Data showed that incidence and diversity of sucking cashew insect pests differed in terms of abundance and distribution within cashew fields in the central and southern zones. Liwale and Kongwa districts recorded higher incidence and severity followed by Mpwapwa, Masasi, Manyoni and Nachingwea districts, respectively. In general, insect pests affecting cashew production in selected locations of southern and central Tanzania have been known in terms of identity (genus level), abundance and distribution; therefore, more efforts on the study should be made on identification to species level to formulate management measures to each specie.
