Analyzing the global human appropriation of net primary production — processes, trajectories, implications. An introduction

Humanity's role in shaping patterns and processes in the terrestrial biosphere is large and growing. Most of the earth's fertile land is used more or less intensively by humans for resource extraction, production, transport, consumption and waste deposition or as living space. Biomass production on cropland, grazing areas and in managed forests dominates area requirements, but other processes such as soil degradation, human-induced fires and expansion of settlements and infrastructure play an increasingly important role as well. The growing human domination of terrestrial ecosystems contributes to biodiversity loss as well as to a reduced capability of ecosystems to deliver vital services such as buffering capacity, soil conservation or self-regulation. This special section is devoted to the presentation of recent research into the patterns, determinants and implications of the human appropriation of net primary production (HANPP), an integrated socio-ecological indicator of land use intensity. By measuring the combined effect of land conversion and biomass harvest on the availability of trophic energy (biomass) in ecosystems, HANPP explicitly links natural with socioeconomic processes and allows for integrated analyses of land systems. This introductory article explains the rationale that links current HANPP research to Ecological Economics and discusses issues of definition and methods shared by all articles included in the special section. Finally, it gives an overview of the individual papers, provides some general conclusions and presents an outlook for future research: a better understanding of long-term trajectories of HANPP, of the significance of trade patterns as well as of the future role of bioenergy are highlighted as important issues to be addressed in the coming years.

The effects of beach characteristics and location with respect to hotel prices

This paper measures the effects of beach characteristics and hotel location with respect to the beach on sun-and-beach hotel prices by using a well-established hedonic perspective. The paper’s main results are that, after controlling for the relevant variables, location in front of a beach increases the price of a room in costal hotels of Catalonia by a figure between 13 and 17%, and that a Blue Flag increases the price by around 11.5%. The effects on hotels’ prices of other beach characteristics (such as beach length, width, sand type or beach services) are also estimated. With these estimates, the paper ranks beaches according to their characteristics and provides a setting to assess different policies regarding beaches from the point of view of hotels, such as regeneration, maintenance or achieving a Blue Flag award.     

A green economy indicator framework for tourism destinations

This paper presents a green economy indicator framework for tourism destinations which has been developed in the case study destination of Bali, Indonesia. Whilst the term “green economy” can have many interpretations, here it refers to the global strategy framework surrounding Rio+20, as well as the policies and strategies being developed by tourism destinations as a response. Many uncertainties remain about the effectiveness of these efforts and how they may be measured. For lesser developed countries in particular, reliable data is often difficult to obtain and this study uses a case study approach to identify the relevant, and measurable, indicators in this context. First, a nominal group technique was applied to identify the green economy issues for local tourism stakeholders. The indicators were then selected based on the green economy literature and a review of the available secondary data for the destination. Data on greenhouse gas emissions from tourism was identified as one of the critical gaps and an estimate is provided to show how this could be obtained and monitored. While this indicator framework was developed specifically for Bali, the case study may be relevant for many other island destinations in the lesser developed world that are experiencing rapid tourism growth.
