摘要

通过直接和间接的社会、经济和环境影响,植树造林是生态系统恢复(ER)和减贫(PA)的一个重要方面。然而,全球现有的植树造林项目主要从生存和生计的狭隘视角来看待经济效益,因此在制定全球贫困问题的长期解决方案时,低估了间接减贫效应和对农业生产的相关负面影响。本研究旨在基于生物物理模型和统计记录,系统研究中国东南部四十年来生态系统恢复的生态、农业和经济效应,并进一步提出通过生态系统恢复实现可持续保护区的升级战略,以满足保护目标和资源需求。我们发现,环境再造促进了植被生长,提高了碳吸收和土壤保持能力。同时,产业转型提高了经济规模和生计多样性(即可支配收入),从而减轻了贫困,改善了社会服务和基础设施条件。然而,第二产业和第三产业的产出逐渐取代了第一产业,畜牧业和林业的发展削弱了农作物种植。种植结构的调整进一步威胁到粮食供应的稳定,特别是在 1999 年之后,有可能导致粮食危机。因此,我们提出了升级森林管理和协调发展政策,以避免粮食危机,改善生计多样性,平衡多维利益,促进可持续发展。研究结果可作为政策制定和应急措施的宝贵参考,以实现更具包容性、复原力和可持续性的巴勒斯坦权力机构。

Moving forward from escaping the poverty trap in China's greenest regions: Examining four decades of socioecological evolution to re-orient sustainable development policies

Afforestation is an important aspect of ecosystem restoration (ER) and poverty alleviation (PA) through direct and indirect social, economic, and environmental effects. However, the existing afforestation projects worldwide have mainly viewed economic benefits through the narrow lens of subsistence and livelihood, thereby underestimating both indirect PA and the associated negative effects on agricultural production when formulating long-term solutions to global poverty. This study aimed to systematically examine the ecological, agricultural, and economic effects of ecosystem restoration in southeastern China over four decades based on biophysical models and statistical records, and further proposed an upgraded strategy for sustainable PA through ER that addresses conservation objectives and resource needs. We found that ER promoted vegetation growth and enhanced carbon sequestration and soil retention. Meanwhile, industrial transformation improved the economic scale and livelihood diversity (i.e., disposable income), which alleviated poverty and improved social services and infrastructure conditions. Nevertheless, the secondary and tertiary industries gradually replaced the primary industry in terms of output, and increased animal husbandry and forestry development weakened crop planting. Planting structure adjustments further threatened the stability of the grain supply, particularly after 1999, which could potentially lead to a grain crisis. Therefore, we propose upgraded forest management and coordinated development policies to avoid a grain crisis, improve livelihood diversity, balance multidimensional benefits, and facilitate sustainable development. Study results serve as a valuable reference for policy formulation and ER measures for more inclusive, resilient, and sustainable PA.

期刊介绍: Applied Geography is a journal devoted to the publication of research which utilizes geographic approaches (human, physical, nature-society and GIScience) to resolve human problems that have a spatial dimension. These problems may be related to the assessment, management and allocation of the world physical and/or human resources. The underlying rationale of the journal is that only through a clear understanding of the relevant societal, physical, and coupled natural-humans systems can we resolve such problems. Papers are invited on any theme involving the application of geographical theory and methodology in the resolution of human problems.
