    Appropriate technologies or appropriating technologies? Technopolitics within artisanal and small-scale mining in Ghana
    (Elsevier, 2025-07-01) Ofori, Alesia Dedaa; Awolorinke, Augustine Chiga; Amankwaah, Gad Amoako
    This article contributes to the discourse on the significance of “appropriate” technologies in formalising artisanal and small-scale gold miners' activities. By raising the question of what or who defines what is “appropriate” for artisanal miners, the paper engages critically with the ignored and complicated spatial and temporal dynamics that underpin miners’ decisions regarding technologies and the impact of these choices on the political ecology of artisanal gold mining. Until recently, technologies used by small and artisanal miners have been known to be crude and rudimentary, with deleterious impacts on the natural environment. Hence, the policy drive to formalise illegal miners has emphasised the essence of appropriate technologies, depoliticizing the complex underpinning factors that shape technology adoption and rejection. Thus, the paper focuses on two technologies that have become prevalent in the artisanal mining scene in Ghana, i.e. the Chinese Changfa and the Trommel, to demonstrate the complex and myriad ways miners determine which technology is appropriate. Appropriate technologies, the paper argues, are determined based on a multifaceted combination of socio-political, economic, ecological, biophysical and cultural factors. The paper concludes by discussing the implications of these observations on the formalisation of artisanal miners amid the increasing demand for energy transition minerals in developing economies.

    Peanut value chain development: the case of Lower Lake Victoria Basin of Kenya
    (MDPI, 2025-03-25) Odunga, George Okoth; Bidzakin, John K.; Okaka, Philip; Okoth, Sheila; Mutsotso, Beneah; Graves, Anil R.
    Peanut is Kenya’s second most important legume after beans, primarily grown in the Nyanza and Western regions. This study maps the peanut value chain in Kenya, aiming to identify key actors, quantify costs and value addition, and outline constraints and opportunities, with a view to upgrading the chain. A cross-sectional survey was conducted among value chain actors in Karachuonyo and Nyakach sub-counties, complemented by secondary data sources. Descriptive statistics were used to analyze socio-economic characteristics, production volumes, pricing, demand trends, and policy-related factors. The findings indicate a predominance of female farmers (68%) in peanut production, though few use improved technologies; only 26% were aware of improved seed varieties, and just 1.5% reported using them. Fertilizer usage was absent, attributed to high costs, soil conditions, and limited knowledge. The wholesale and processing segments are male-dominated, largely due to capital intensity and travel requirements, while female traders dominate the retail sector. Strengths Weaknesses Opportunity and Threats (SWOT) analysis highlighted the significant potential of favorable production ecologies, processing options, and robust demand in local and international markets. Key constraints identified include limited seed availability, high fertilizer costs, pest issues, and declining soil fertility. Policy implications include increasing access to affordable inputs, promoting gender-inclusive programs, investing in agricultural research and infrastructure, supporting sustainable farming practices, and fostering public-private partnerships to expand processing and market access.
