Cañadas-López, Álvaro ; Rade-Loor, Diana Yasbhet ; Siegmund-Schultze, Marianna ; Iriarte-Vera, Marys ; Domínguez-Andrade, Juan Manuel ; Vargas-Hernández, Jesús ; Wehenkel, Christian (2018-10-04)

Jatropha is promoted as a pro-poor bioenergy plant, while basic information about its productivity, age of maximum production, and oil content are missing. This study aims to determine the seed yield (dry weight) for three INIAP elite jatropha accessions, and to evaluate the changes in physical and chemical seed traits at the different fruit ripening stage in a split-plot design. Maximum seed p...

Scaling Effects in Spatial Multi-Criteria Decision Aggregation in Integrated River Basin Management

Taha, Rania ; Dietrich, Jörg ; Dehnhardt, Alexandra ; Hirschfeld, Jesko (2019-02-20)

For river basin management plans (RBMPs), measures are aggregated from smaller spatial units (e.g., water bodies) to the catchment or basin scale. River basin management plans measures in integrated management are evaluated using multiple criteria, e.g., ecological and socio-economiccriteria, etc. Therefore, aggregation often combines spatial analysis and multi-criteria decision analysis (MCDA)...

Spatial Data - potential European Key Biodiversity Areas

Bilz, Melanie (2019-06)

This dataset contains the spatial information for the dissertation on "European Red Lists and their potential to inform Key Biodiversity Area identification". Distribution data on species (amphibians, beetles, butterflies, mammals, molluscs, plants, reptiles) that are endemic to Europe and threatened with extinction was collected in 10x10 km grid cells.

European Red Lists and their potential to inform Key Biodiversity Area identification

Bilz, Melanie (2019)

Key Biodiversity Areas (KBAs) are sites that contribute significantly to the global persistence of biodiversity, encompassing the composition of biodiversity as well as ecological and biological processes. In 2016, the conservation and scientific community agreed upon a global KBA Standard, outlining five different criteria for identifying KBA sites. One of these criteria is the occurrence of s...

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...

Colwill, Simon Christopher (2019)

The research results benefit all stakeholders in the field of landscape architecture by generating a breadth of new knowledge that can be used to enhance the design, construction and maintenance of landscape architecture works. The main results of this research are the resulting monitoring methods for assessing weak points, vulnerabilities and general performance of built landscape elements in ...

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...
