    This dissertation links the natural and social sciences, using modeling techniques to enhance understanding of the functioning of a complex ecosystem and its relevance to humans. For this purpose, I developed a Regional Unified Metatomodel of the Brazilian Amazon (RUMBA) to simulate the Amazon forest provision of ecosystem goods and services and their contribution to human economy and welfare. The model was also used to simulate the potential effect of an incentive to reduce deforestation in return for a payment for avoided releases of carbon into the atmosphere. Simulation was done from 1975 to 2100, with calibration performed for the first 25 years, and for four scenarios: a baseline scenario, based on historical trends, and four alternative scenarios based on different assumptions and policy choices. The baseline scenario shows deforestation proceeding at high rates, leading to decreasing provision of forest goods and services and increasing economic growth. The growth of GRP per capita, on the other hand, remains much smaller than that of GRP. Regional welfare decreases significantly over the simulated period. The overall monetary contribution of ecosystem goods and services to the regional economy is estimated as 5 times the GRP in year 2100. Scenarios of increased investment in development yielded higher economic growth accompanied by lower levels of welfare, while opposite trends were found for scenarios of higher investment in human, knowledge and natural capital. Finally, results also show that in order for a monetary compensation to represent a significant incentive to land owners to reduce deforestation, higher prices for avoided carbon emissions would have to be set than current prices of the emerging carbon market. Main research findings are that increasing land use change in the Brazilian Amazon incurs significant losses of ecosystem services without this being adequately offset by increasing monetary income or welfare of people. This reseach has also found that in the absence of significant incentives from global beneficiaries for any one ecosystem service, or a combination of incentives addressing several types of ecosystem services, rational land uses at the local level lead to sub-optimal provision of these services from the global perspective

    A methodology for adaptable and robust ecosystem services assessment

    Ecosystem Services (ES) are an established conceptual framework for attributing value to the benefits that nature provides to humans. As the promise of robust ES-driven management is put to the test, shortcomings in our ability to accurately measure, map, and value ES have surfaced. On the research side, mainstream methods for ES assessment still fall short of addressing the complex, multi-scale biophysical and socioeconomic dynamics inherent in ES provision, flow, and use. On the practitioner side, application of methods remains onerous due to data and model parameterization requirements. Further, it is increasingly clear that the dominant one model fits all paradigm is often ill-suited to address the diversity of real-world management situations that exist across the broad spectrum of coupled human-natural systems. This article introduces an integrated ES modeling methodology, named ARIES (ARtificial Intelligence for Ecosystem Services), which aims to introduce improvements on these fronts. To improve conceptual detail and representation of ES dynamics, it adopts a uniform conceptualization of ES that gives equal emphasis to their production, flow and use by society, while keeping model complexity low enough to enable rapid and inexpensive assessment in many contexts and for multiple services. To improve fit to diverse application contexts, the methodology is assisted by model integration technologies that allow assembly of customized models from a growing model base. By using computer learning and reasoning, model structure may be specialized for each application context without requiring costly expertise. In this article we discuss the founding principles of ARIES - both its innovative aspects for ES science and as an example of a new strategy to support more accurate decision making in diverse application contexts

    The present paper proposes a micro-econometric methodology for the economic valuation of the impact ofecosystem services in selected economic sectors. In the context of natural capital and ecosystem accounting, webuilt a four steps valuation protocol. The methodology is applied to the valuation of freshwater in theAnkeniheny-Zahamena Forestry Corridor (CAZ), Madagascar \u2013a country partner with the Wealth Accountingand the Valuation of Ecosystem Services (WAVES). Our results corroborate the intuition that understanding thevalue of water in its alternative uses is a key to fostering informed debate on water management and allocationin the CAZ area. More generally, this study provides a solid contribution towards a more e\ufb00ective way to elicitand record nature's ecosystem services contribution to the econom

    Targeting and implementing payments for ecosystem services: Opportunities for bundling biodiversity conservation with carbon and water services in Madagascar

    No full text
    Payments for Ecosystem Services (PES) are generating a lot of attention among conservationists because they have the potential to create new funding opportunities for biodiversity protection and other ecosystem services that contribute to human well-being. A number of recent publications have suggested ways to target and implement PES projects in order to maximize their cost-effectiveness and efficiency, and the Heredia Declaration (this issue) sets forth a list of agreed-upon principles concerning the use of PES schemes. One of those principles concerns the "bundling" of joint products of intact ecosystems in PES schemes in order to maximize the benefits to society. There have been several recent studies focusing on the degree of overlap between biodiversity and other ecosystem services and therefore the opportunities and constraints to bundling these services. Building on this idea, the bulk of this paper focuses on developing a method for selecting sites for PES where the main interest is to bundle biodiversity with other ecosystem services. We focus our analysis on Madagascar, a country with globally important biodiversity that is also beginning to explore the utility of PES as a conservation mechanism. Specifically, we assess the opportunities for bundling biodiversity conservation with carbon and water services at the national scale and identify where using PES to protect these areas of multiple benefits would be most cost-effective and efficient. This analysis identifies almost 30,000 km2 -- out of 134,301 km2 -- of natural habitat that could potentially meet biodiversity conservation goals and protect additional ecosystem services through a PES scheme. One of the places identified by our methodology corresponds to an ongoing conservation project that has already begun using payments from carbon emission reductions to protect standing forests and restore important biodiversity corridors -- the Ankeniheny-Mantadia-Zahamena Biodiversity Conservation and Restoration Project. This project site was selected for its high biodiversity and carbon values, lending credibility to our spatial targeting methodology and providing a case study to draw insights on how multiple-benefit PES schemes can be implemented in biodiversity "hotspots". In the discussion section of this paper we draw on experiences from this project to consider how many of the principles outlined in the Heredia Declaration affect implementation of PES schemes in Madagascar, providing lessons for similar countries experimenting with PES for biodiversity conservation.Biodiversity Bundling Carbon Madagascar Payments for ecosystem services Water quality
