在本文中，我们评估的经济，自然资本和生态系统服务的影响的战略，保护哥伦比亚丰富的自然资本禀赋。具体而言，我们认为政府计划的建议，建立生态系统服务付费（PES），实施更可持续的森林牧场系统和扩大栖息地银行。我们开发并应用与空间土地利用土地覆盖（LULC）和生态系统服务建模（IEEM+ ESM）相关联的综合经济环境建模（IEEM）平台，从可持续经济发展和代际财富的角度揭示这些计划的多维影响。推进国家的最先进的综合经济环境建模，我们的框架第一次整合了自然资本，生态系统服务和经济系统之间的动态内生反馈，以充分捕捉自然资本和生态系统服务流量的变化如何影响经济，反之亦然。我们的方法定量建模的经济，自然资本和生态系统服务作为一个综合的和复杂的系统在高水平的空间分辨率在哥伦比亚的32个部门。我们展示了如何在公共政策和投资分析中重视生物多样性，可以在经济上可行的投资和不可行的投资之间产生差异。如果不考虑生物多样性的价值，拟议的生态系统服务补偿和栖息地银行计划在经济上是不可行的。包括生物多样性的价值在内，生态系统服务补偿和生境银行都成为强有力的投资主张，净现值分别为44亿美元和49亿美元。增强哥伦比亚的自然资本基础和未来生态系统服务供应的经济和环境效益得到证明，并按区域区分，这提供了一个强有力的经验证据基础，为政策的空间目标，以最大限度地提高经济，环境和社会成果。
In this paper we evaluate the economic, natural capital and ecosystem services impact s of strategies for conserving Colombia’s rich natural capital endowment. Specifically, we consider Government program proposals for establishing Payment for Ecosystem Services (PES), implementing more sustainable silvopastoral systems and expanding habitat banking. We develop and apply the Integrated Economic - Environmental Modeling (IEEM) Platform linked with spatial Land Use Land Cover (LULC) and Ecosystem Services Modeling ( IEEM+ ESM) to shed light on the multi-dimensional impacts of these programs from the perspective of sustainable economic development and intergenerational wealth. Advancing the state-of-the-art in integrated economic-environmental modeling, our framework for the first time integrates dynamic endogenous feedbacks between natural capital, ecosystem services and the economic system to fully capture how changes in natural capital and ecosystem service flows affect the economy and vice versa. Our approach quantitatively models the economy, natural capital and ecosystem services as one integrated and complex system at a high level of spatial resolution across Colombia’s 32 Departments. We demonstrate how valuing biodiversity in public policy and investment analysis can make the difference between an investment that is economically viable and one that is not. Without accounting for the value of biodiversity, the proposed PES and habitat banking programs are not economically viable. Including the value of biodiversity, both PES and habitat banking become strong investment propositions with a net present value of US$4.4 billion and US$4.9 billion, respectively. The economic and environmental benefits of enhancing Colombia’s natural capital base and future ecosystem service supply are demonstrated and regionally differentiated, which provides a strong empirical evidence base to inform the spatial targeting of policies to maximize economic, environmental and social outcomes .
