    Inequalities in the production and dissemination of biodiversity conservation knowledge on Tanzania: A 50-year bibliometric analysis
    (Elsevier BV, 2023-03) Mathew Bukhi Mabele; Ng'winamila Kasongi; Happiness Nnko; Iddi Mwanyoka; Wilhelm Andrew Kiwango; Enock Makupa
    Tanzania is a popular keyword in biodiversity conservation publications, but, trends in research collaborations, scientific knowledge production and authors’ productivity remain underexplored. Using the Web of Science database and bibliometric analysis techniques, we fill this gap by examining the trends between 1972 and 2021. The database search produced 1517 records. We filtered the data using document types and subject categories as criteria. We used bibliometrix package in R software to analyse 1354 peer-reviewed publications. Through performance analysis, science mapping and network analysis, journal publications, author and institutional productivity, disciplinary focus, funding agencies and network of authorship and institutional collaborations are identified. Whereas African Journal of Ecology, PLoS One and Biological Conservation top the scientific production list, Biological Conservation, Conservation Biology and Oryx top the citation list. Major research inequalities are revealed where, European and North American centricity dominates in author productivity (number of papers, total citations and h-index), author collaborations networks and research funding agencies. Out of the top 20 highly cited papers, eleven had no Tanzanian author. The list had only two papers with Tanzanians as first authors. We observed a proliferation of international researchers and decreased productivity of local researchers in the last 30 years. Organisations from Europe and North America provided much of the research funding in Tanzania. This is possibly one of the first attempts to illustrate empirically how production and dissemination of conservation knowledge are entrenched in unequal structures at a country level. We thus contribute to the burgeoning literature on decolonisation of conservation research, by proposing five practical areas to dismantle the unequal system of knowledge production.

    Wood-saving stoves: an opportunity for households to switch technology and contribute to reduction of deforestation and carbon dioxide emission. The case of Kilimanjaro region, Tanzania
    (Begell House, 2014) Francis X. Mkanda; Stephen Mutimba; Iddi Mwanyoka; Richard Kibulo; Agrey Mawole
    This study examines the energy-consumption pattern in the Kilimanjaro Region in the context of the energy-switch principle and its potential contribution to reduction of deforestation and carbon dioxide emission. Such information will be useful in designing an energy-improvement strategy on emissions reduction linked to a carbon-credit-earning scheme, preferably through the United Nations Development Program (UNDP) "Millennium Development Goal Carbon Initiative," and other carbon markets. The results show that the preferred energy source is firewood, and a majority of respondents are still using 3-stone stoves. Wood-saving stoves are reducing firewood consumption and carbon dioxide emission by 51%, which is an opportunity to contribute to combating deforestation, land degradation, and carbon dioxide (CO2) emission and benefit from the Carbon Initiative. However, considering the high transaction and distribution costs of energy-saving technologies in Tanzania, this opportunity will only be meaningful if the government removed such constraints.
