It is well recognized that ecological systems generate a spectrum of diverse benefits that are vital to humankind. Sustainable environmental management requires an adequate consideration of ecosystem goods and services. The problem, however, is that many of the ecological and social amenities are not currently incorporated into the decision-making process. A fundamental issue is getting at the ...
Understanding the economic value of nature and the services it provides to humanity has become increasingly important for local, national and global policy and decision making. However, problems arise in that it is difficult to obtain meaningful values for goods and services that ecosystems provide which have no formal market, or are characteristically intangible. Additional problems occur when...
Management of natural resources for the production of ecosystem services, which are vital for human well-being, is necessary even when there is uncertainty regarding system response to management action. This uncertainty is the result of incomplete controllability, complex internal feedbacks, and non-linearity that often interferes with desired management outcomes, and insufficient understandin...
Understanding cultural preferences toward different ecosystem services is of great importance for conservation and development planning. While cultural preferences toward plant species have been long studied in the field of plant utilisation, the effects of ethnicity on ecosystem services identification and valuation has received little attention. We assessed the effects of ethnicity toward dif...
In the light of ongoing global urbanization and the high pace of resource consumption, there is an urgent need to foster compact cities. Currently, however, we lack integrative guidelines on how to manage trade-offs between urban densification and the provision of green space. Against this background, this study applies the concepts of green infrastructure and ecosystem services to develop a gu...
This paper presents a dynamic systems model that shows how different land use patterns degrade the value of ecosystem services provided by the Brazilian Amazonia. The model consists of four sectors: (1) deforestation drivers; (2) land use/cover; (3) ecosystem services; and (4) ecosystem valuation. The deforestation drivers sector models the economic and social incentives that small farmers and ...
We thank Bridgewater and Babin (1) for their perspective. We are aware of, and appreciate, the consideration of ecosystem services in the management of Biosphere Reserves. However, we see a strong imperative for establishing a protected area (PA) category focused specifically on protecting ecosystem services, for several key reasons articulated in our paper (2) and below. First, although China ...
This research is concerned with the following environmental research questions: socio-ecological system complexity, especially when valuing ecosystem services; ecosystems stock and services flow sustainability and valuation; the incorporation of scale issues when valuing ecosystem services; and the integration of knowledge from diverse disciplines for governance and decision making. In this cas...
The purpose of this paper is to integrate the concepts of ecosystem services and disservices when assessing the efficacy of using urban forests for mitigating pollution. A brief review of the literature identifies some pollution mitigation ecosystem services provided by urban forests. Existing ecosystem services definitions and typologies from the economics and ecological literature are adapted...
