Agricultural Mechanization in Rural Sierra Leone: Productivity, Equity, and Environmental Trade‑offs - A Case Study of Makump America, Bombali District (2015-2023)

This study examines the effects of the transition from subsistence to mechanized agriculture in rural Sierra Leone, focusing on Makump America, Mayoloh Section, Bombali District, from 2015 to 2023. A mixed‑methods research design was employed, combining a structured household survey (N = 30), semi‑structured key informant interviews (n = 15), five focus group discussions (8-10 participants each), and field observations. Quantitative data were analyzed using descriptive statistics, while qualitative data were subjected to thematic analysis. The findings reveal a paradoxical outcome: mechanization significantly improves agricultural productivity and household incomes, with 63% of farmers reporting yield increases and 70% experiencing income growth. However, these aggregate gains mask deep socioeconomic disparities. Manual labour demand declined for 67% of respondents, displacing landless workers and triggering rural‑urban migration. Gender exclusion is pronounced, as women constitute 37% of the sample but face systemic barriers to accessing machinery and training. Major adoption barriers include high equipment costs (87%), lack of technical knowledge (63%), inadequate credit access (53%), and poor infrastructure (47%), leading to widespread “stranded mechanization” where machinery falls into disuse. Environmental outcomes are mixed: 43% of farmers observed increased soil erosion, 37% reported improved soil fertility, and 20% noted reduced biodiversity. The discussion situates these results within modernization theory, labour market theory, and the environmental sustainability framework, highlighting that mechanization’s benefits are filtered through pre‑existing inequalities. The study concludes that mechanization alone is insufficient for equitable rural development. Without integrated policies that address financial access, technical training, gender inclusion, and environmental safeguards, mechanization risks reinforcing the very disparities it aims to reduce. These findings provide the first localized, multi‑dimensional empirical evidence on agricultural mechanization in Sierra Leone and offer actionable insights for policymakers and development practitioners in similar Sub-Saharan African contexts.
