Mapping the Recreational Value of Non-Urban Ecosystems across Europe: Combining Meta-Analysis and GIS

Schägner, Jan Philipp ; Brandner, Luke ; Hartje, Volkmar ; Maes, Joachim ; Paracchini, Maria-Luisa (2016)

We map recreational visits and the economic value per visit spatially explicit across Europe’s non-urban ecosystems using GIS, meta-analysis and geostatistical modelling techniques. Therefore, we develop a meta-analytic visitor arrival function and a meta-analytic value transfer function by regression analysis. Primary data on the dependent variables are collected from visitor monitoring and v...

GIS-Based Mapping of Ecosystem Services: The Case of Coral Reefs

Brandner, Luke ; Eppink, Florian ; Schägner, Jan Philipp ; Beukering, Pieter van ; Wagtendonk, Alfred (2015-06-03)

This chapter illustrates the process of mapping ecosystem service values with an application to coral reef recreational values in Southeast Asia. The case study provides an estimate of the value of reef-related recreation foregone, due to the decline in coral reef area in Southeast Asia, under a baseline scenario for the period 2000 – 2050. This value is estimated by combining a visitor model, ...

Monitoring recreation across European nature areas: A geo-database of visitor counts, a review of literature and a call for a visitor counting reporting standard

Schägner, Jan Philipp ; Maes, Joachim ; Brandner, Luke ; Paracchini, Maria Luisa ; Hartje, Volkmar ; Dubois, Gregoire (2017-03-17)

Nature recreation and tourism is a substantial ecosystem service of Europe’s countryside that has a substantial economic value and contributes considerably to income and employment of local communities. Highlighting the recreational value and economic contribution of nature areas can be used as a strong argument for the funding of protected and recreational areas. The total number of recreation...

Mapping ecosystem services' values: Current practice and future prospects

Schägner, Jan Philipp ; Brandner, Luke ; Maes, Joachim ; Hartje, Volkmar (2013-03-27)

Mapping of ecosystem services' (ESS) values means valuing ESS in monetary terms across a relatively large geographical area and assessing how values vary across space. Thereby, mapping of ESS values reveals additional information as compared to traditional site-specific ESS valuation, which is beneficial for designing land use policies for maintaining ESS supply. Since the well-known article b...

Social preferences for adaptation measures to conserve Australian birds threatened by climate change

Garnett, Stephen T. ; Zander, Kerstin K. ; Hagerman, Shannon ; Satterfield, Terre A. ; Meyerhoff, Jürgen (2017-01-10)

Debate about climate change adaptation for biodiversity, and the ethics and consequences of assisted colonization in particular, has polarized professional opinion but the views of the wider community are unknown. We tested four hypotheses about the acceptability of adaptation strategies among a sample of the Australian general public using a combination of direct questions and a choice experim...

Response anomalies in discrete choice experiments for environmental valuation

Oehlmann, Malte (2019)

The use of discrete choice experiments (DCEs) to value environmental goods and services has been rapidly increasing over the last years. However, many studies call into question the validity of this approach. Biases in welfare estimates derived from DCEs may arise from response behavior which is not fully consistent with one or more of the assumptions underlying stated preference approaches. Si...

Mapping recreational visits and values of European National Parks by combining statistical modelling and unit value transfer

Schägner, Jan Philipp ; Brander, Luke ; Maes, Joachim ; Paracchini, Maria Luisa ; Hartje, Volkmar (2016)

Recreation is a major ecosystem service and an important co-benefit of nature conservation. The recreational value of National Parks (NPs) can be a strong argument in favour of allocating resources for preserving and creating NPs worldwide. Managing NPs to optimize recreational services can therefore indirectly contribute to nature conservation and biodiversity protection. Understanding the dri...

Spatio-temporal analysis of landslide hazard in southern Kyrgyzstan Using GIS and remote sensing data

Golovko, Darya (2019)

Large areas in southern Kyrgyzstan are affected by intensive landsliding, which results in the loss of human life and damages to the housing and infrastructure. A quantitative landslide hazard assessment based on a systematic landslide record is needed to better understand landslide processes in the region and to implement more effective hazard mitigation measures. Landslide investigations have...

Spatially explicit assessment of recreational ecosystem services

Schägner, Jan Philipp (2019)

Spatial assessments and mapping of ecosystem service values has become a widely addressed research issue. It is more and more used to consult land-use and conservation policies as well as landscape planning. Nevertheless, a variety of methods is used for ecosystem service value mapping, which lead to maps with a broad range of quality and accuracy. Still, little consensus has been reached on wh...

Nutrient recycling from sanitation and energy systems to the agroecosystem - Ecological research on case studies in Karagwe, Tanzania

Krause, Ariane ; Kaupenjohann, Martin ; George, Eckhard ; Köppel, Johann (2015)

Open cycles of organic carbon and nutrients cause soil degradation. Procedures such as ecological sanitation (EcoSan), bioenergy and Terra Preta practice (TPP) can contribute to closing nutrient cycles and may, in addition, sequester carbon. This paper introduces three projects in Karagwe, Tanzania, and their applied approach of integrated resource management to capture carbon and nutrients fro...

Organic wastes from bioenergy and ecological sanitation as a soil fertility improver: a field experiment in a tropical Andosol

Krause, Ariane ; Nehls, Thomas ; George, Eckhard ; Kaupenjohann, Martin (2016)

Andosols require the regular application of phosphorus (P) to sustain crop productivity. On an Andosol in NW Tanzania, we studied the short-term effects of amending standard compost, biogas slurry and CaSa compost (containing biochar and sanitized human excreta) on (i) the soil's physico-chemical properties, on (ii) biomass growth and crop productivity, and on (iii) the plants' nutrient status....

Reducing global CO2 emissions with the technologies we have

Ward, Hauke ; Radebach, Alexander ; Vierhaus, Ingmar ; Fügenschuh, Armin ; Steckel, Jan Christoph (2017)

The energy intensities of the various industrial sectors differ considerably across countries. This suggests a potential for emissions reductions through improved accessibility to efficient technologies. This paper estimates an upper-bound CO2 emission mitigation potential that could theoretically be achieved by improved access to efficient technologies in industrial sectors. We develop a linea...

Assessing carbon dioxide emission reduction potentials of improved manufacturing processes using multiregional input output frameworks

Ward, Hauke ; Burger, Mia ; Chang, Ya-Ju ; Fürstmann, Paul ; Neugebauer, Sabrina ; Radebach, Alexander ; Sproesser, Gunther ; Pittner, Andreas ; Rethmeier, Michael ; Uhlmann, Eckart ; Steckel, Jan Christoph (2016)

Evaluating innovative process technologies has become highly important within the last decades. As standard tools different Life Cycle Assessment methods have been established, which are continuously improved. While those are designed for evaluating single processes they run into difficulties when it comes to assessing environmental impacts of process innovations at macroeconomic level. In this...

Truncation Error Estimates in Process Life Cycle Assessment Using Input‐Output Analysis

Ward, Hauke ; Wenz, Leonie ; Steckel, Jan Christoph ; Minx, Jan (2017)

Process life cycle assessment (PLCA) is widely used to quantify environmental flows associated with the manufacturing of products and other processes. As PLCA always depends on defining a system boundary, its application involves truncation errors. Different methods of estimating truncation errors are proposed in the literature; most of these are based on artificially constructed system complet...

The effect of industry delocalization on global energy use: A global sectoral perspective

Forin, Silvia ; Radebach, Alexander ; Steckel, Jan Christoph ; Ward, Hauke (2018)

Sectoral production technologies differ largely across countries, so do sectoral energy intensities. Hence, shifts in production locations within global sectors, possibly caused by environmental regulations, are likely to have an impact on aggregated energy usage and emissions. Applying a Logarithmic Mean Divisia Index decomposition we decompose changes of sectoral energy use from 2001–2011 int...

My dissertation had as its starting point the intention of two Tanzanian farmer's initiatives and their German partners to disseminate sustainable cooking and sanitation technologies to smallholder households in Karagwe District, in northwest Tanzania (TZ). These locally developed and adapted technologies include improved cook stoves, such as microgasifiers, and a system combining biogas digest...

Urban climate and heat stress: how likely is the implementation of adaptation measures in mid-latitude cities? The case of façade greening analyzed with Bayesian networks

Sprondel, Nora ; Donner, Julie ; Mahlkow, Nicole ; Köppel, Johann (2016)

Background Urban heat is a challenge for mid-latitude cities possibly aggravated by global climate change making it necessary to adapt the urban fabric. Façade greening has been identified as an important measure to adjust the building stock and new buildings to adverse climatic impacts. Yet, little is known on factors that influence implementation probabilities for adaptation measures. Theref...

To Pay or Not to Pay: Competing Theories to Explain Individuals’ Willingness to Pay for Public Environmental Goods

Liebe, Ulf ; Preisendörfer, Peter ; Meyerhoff, Jürgen (2010)

Several theories have been proposed in an attempt to explain individuals’ willingness to pay (WTP) for public environmental goods. While most studies only take into account a single theory, this article discusses competing theories. These include, in addition to a basic economic model, the theory of public goods, Ajzen’s theory of planned behavior, and Schwartz’s norm-activation model. Empirica...
