本研究は、ガーナのカカオ生産に対する気候変動と土地利用/土地被覆変化の複合的影響を混合手法で分析。気温上昇と不規則な降雨がカカオ生産変動の31.3%を説明し、森林面積は40年で42%減少。農家は土壌劣化や病害虫の増加を報告しており、持続可能な土地管理と気候スマート農業の重要性を示す。

This study examines the combined effects of climate change and land use/land cover changes on cocoa production in Ghana using a mixed-methods approach. Temperature increases and erratic rainfall explain 31.3% of annual cocoa yield variability, while closed forest cover declined by 42 percentage points over four decades. Farmers report declining soil fertility and increased pest outbreaks. Integrated interventions such as sustainable land management and climate-smart agriculture are recommended to enhance resilience.

📄 Abstract（原文）
ABSTRACT Cocoa production in Ghana, a key global producer, is increasingly threatened by climate change and Land Use/Land Cover Changes, endangering the livelihoods of millions of smallholder farmers. While climate change and land use/land cover changes have often been examined in isolation, research on their combined effects is rare. This study investigates long-term climate trends and land use/land cover dynamics in the Atwima Mponua District, Ghana, and examines their combined (i.e., co-occurring influences or interacting pressures) effects on cocoa production. A mixed-methods approach integrates quantitative climate and land use data with qualitative insights to assess yield implications. The study draws on multiple data sources, including household surveys with 200 farmers, semi-structured interviews, and climate records from 1980 to 2020, analyzed using Mann-Kendall trend tests. Land use and land cover changes were assessed using satellite imagery classified with random forests. Results indicate a significant rise in temperature and erratic rainfall patterns, which together explain 31.3% of the variability in annual cocoa production. Closed forest cover declined by 42 percentage points over four decades, mainly between 2010 and 2020, driven by deforestation, population growth, and unsustainable farming practices. Farmers reported declining soil fertility, increased pest and disease outbreaks, and rising production costs as perceived effects of climate and land use/land cover changes. Integrated interventions, including sustainable land management, climate-smart agriculture, and agroforestry, are crucial in enhancing smallholder farmers’ resilience. These findings contribute to the United Nations Sustainable Development Goals on hunger, climate action, and land conservation.
