In the context of emerging international trade regulations on deforestation-free commodities, the drivers of households' deforestation in conservation landscapes are of interest. The role of households' livelihood strategies including cocoa production, and the effects of human-elephant conflict are investigated. Using a unique dataset from a survey of 1035 households in the Tridom landscape in the Congo basin, the spatial autoregressive model shows that: (1) Households imitate the deforestation decisions of their neighbors; (2) A marginally higher income from cocoa production-based livelihood portfolios is associated with six to seven times higher deforestation compared to other livelihood strategies with a significant spillover effect on neighboring households' deforestation. The increase in income, mainly from cocoa production-based livelihoods in open-access systems can have a negative effect on forests. Households with a higher share of auto-consumption are associated with lower deforestation. If economic development brings better market access and lower auto-consumption shares, this is likely to positively influence deforestation. Without proper land use planning/zoning associated with incentives, promoting sustainable agriculture, such as complex cocoa agroforestry systems, may lead to forest degradation and deforestation.
在关于无森林砍伐商品的国际贸易法规不断涌现的背景下,保护区域内家庭森林砍伐的驱动因素备受关注。本研究调查了家庭生计策略(包括可可生产)的作用以及人象冲突的影响。利用刚果盆地特里多姆地区1035户家庭的独特调查数据集,空间自回归模型显示:(1)家庭会模仿邻居的森林砍伐决策;(2)与其他生计策略相比,基于可可生产的生计组合带来的收入略有增加,会使森林砍伐率高出六至七倍,且对邻近家庭的森林砍伐有显著的溢出效应。在开放获取系统中,主要来自基于可可生产的生计的收入增加可能会对森林产生负面影响。自给自足比例较高的家庭森林砍伐率较低。如果经济发展带来更好的市场准入和更低的自给自足比例,这可能会对森林砍伐产生积极影响。如果没有与激励措施相关的适当土地利用规划/分区,推广可持续农业,如复杂的可可农林业系统,可能会导致森林退化和砍伐。
