Abstract:
This study investigated the perception of drought by cocoa farmers and explored the
effectiveness of adaptive strategies (ASs) used in smallholding farms in the transboundary region
between Ghana and Togo. Drought significantly threatens cocoa production in this region, affecting
farmers’ livelihoods and cocoa supply chains. This study used a multistage sampling approach, which
involved surveys with questionnaires administered to 330 cocoa farmers throughout the study area,
along with on-site observations. Statistical analysis included binary logistic and Poisson regression
models to explore the relationship between farmer socioeconomic characteristics and adaptation
practices. The findings revealed that cocoa farmers in the region have a nuanced understanding of
drought, attributed to changing climatic patterns and unsustainable land management practices such
as deforestation. To mitigate its impacts, farmers employ a variety of ASs, including investment
in farm management, soil management, and intercropping with crop diversification. Furthermore,
socioeconomic factors, including age, formal education, household size, land tenure right, adaptation
cost assessment, and an underestimation of self-efficacy, were shown to affect the choice in the AS.
Among the ASs adopted, only farm management practices (weeding, pruning, fertilizer application,
etc.) significantly improved the cocoa yield. This study contributes to understanding drought as a
critical issue for cocoa farmers and the adaptation practices used by smallholder cocoa farmers. Given
that among the strategies adopted, only farm management practices, also known as good agricultural
practices (GAPs), significantly improves yield, this study recommends well-designed and innovative
packages of sustainable farm management based on farm and owner characteristics. These include
irrigation schemes, timely soil fertilizer monitoring and supply, and the provision of drought-resistant
varieties along with technical itineraries. Additional interventions require drought emergency
responses, with other factors such as education and financial support mechanisms expected to
improve farmers’ timely decision-making to adapt and improve cocoa production resilience to
drought episodes in international transboundary regions with complex governance structures.
