| dc.description.abstract | 本研究探討了坦尚尼亞小農戶在糧食和經濟作物生產之間的權衡取捨，並著重於其對家庭糧食安全的影響。研究利用坦尚尼亞國家小組調查的數據，評估影響農民作物生產偏好的社會經濟、制度和環境因素。研究確定了影響農民偏好的社會經濟因素，評估了經濟作物生產對家庭糧食安全的影響，並分析了製度和環境條件在影響生產決策中的作用。研究結果表明，年齡、性別、教育程度和土地面積等社會經濟特徵顯著影響作物選擇。家庭飲食多樣性與經濟作物產量呈負相關，這表明優先種植經濟作物的家庭可能更容易受到糧食不安全的影響。本研究有助於促進永續農業的政策討論，強調需要採取平衡的措施，在不損害糧食安全的前提下提高農村收入。 | zh_TW |
| dc.description.abstract | The study explores the trade-offs between food and cash crop production among smallholder farmers in Tanzania, focusing on their impact on household food security. It uses data from the Tanzania National Panel Survey to evaluate socio-economic, institutional, and environmental factors influencing farmers' crop production preferences. The research identifies socio-economic factors that shape farmers' preferences, assesses the impact of cash crop production on household food security, and analyzes the role of institutional and environmental conditions in shaping production decisions. The findings reveal that socioeconomic characteristics, such as age, gender, education, and land size, significantly influence crop choice. Household dietary diversity and cash crop output are negatively correlated, suggesting that households prioritizing cash crops may be more vulnerable to food insecurity. The study contributes to policy discussions on sustainable agriculture, emphasizing the need for a balanced approach that enhances rural incomes without compromising food security. | en |
