Do You Have 5 Minutes To Spare? –The Challenges Of Stakeholder Processes In Ecosystem Services Studies

Peer-reviewed publication
Octobre, 2014

Operationalization of the ecosystem services (ES) concept for improved natural resource management and decision support
cannot, thus far, be rated as satisfactory. Participation of stakeholders is still a major methodical and conceptual challenge for implementing ES. Therefore, we conducted an online survey and a literature analysis to identify benefits and challenges of the
application of ES in participatory processes. The results show that the purpose of stakeholder engagement is very diverse as a

Are interest groups different in the factors determining landscape preferences?

Peer-reviewed publication

Europe

In the last decades, rural landscape in Europe has evolved from an agricultural by-product to an important
public good. This development creates not only new challenges to farming practices, it also makes
participation and public involvement an indispensable tool for sustainable landscape planning. This is
especially true for many European mountain regions, where tourism represents an important source of
income and conflicts between locals’ and tourists’ interests should be avoided. In our study, we analyze

The ecological and economic consequences of changing land use in the southern Drakensberg grasslands, South Africa

Peer-reviewed publication

Afrique australe

The grassland biome of the southern Drakensberg region of South Africa is characterized by a relatively rich floral biodiversity, including a high level of endemics.  Land use in the area was traditionally dominated by livestock ranching based mainly on indigenous grassland that conserved biodiversity to some degree.  Currently however, market demands and risk factors are shifting land use in the area to a matrix of beef, cropping, dairy and particularly, towards plantation forestry.  A spreadsheet model was constructed to understand how expected land use conversion will likely influence th

Agricultural Set-aside Programs and Grassland Birds: Insights from Broad-scale Population Trends

Peer-reviewed publication
Octobre, 2008
États-Unis d'Amérique

The Conservation Reserve Program (CRP) is a voluntary set-aside program in the United States designed to amelioratesoil erosion, control crop overproduction, enhance water quality, and provide wildlife habitat by replacing crops with other forms of land cover. Because CRP includes primarily grass habitats, it has great potential to benefitdeclining North American grassland bird populations. We looked at the change in national and state population trends of grassland birds and related changes to cover-specific CRP variables (previous research grouped all CRP practices).

Perception and Value of Nature in Urban Landscapes: a Comparative Analysis of Cities in Germany, Chile and Spain

Peer-reviewed publication
Septembre, 2008

Allemagne
Espagne

Cities are not socially homogenous, but divided into socially and structurally differentiated sub-units. Likewise, the individuals of a community, city or neighbourhood present specific behavioural patterns and uses with respect to their public green areas. This premise has led us to explore the question of how the perceptions, uses, and behaviours of people from different countries, cultures, and socioeconomic levels in Chile, Germany and Spain differ or coincide as far as urban nature and landscapes are concerned.

Landscapes‘ Capacities to Provide Ecosystem Services – a Concept for Land-Cover Based Assessments

Peer-reviewed publication
Décembre, 2009
Allemagne

Landscapes differ in their capacities to provide ecosystem goods and services, which are the benefits humans obtain
from nature. Structures and functions of ecosystems needed to sustain the provision of ecosystem services are altered
by various human activities. In this paper, a concept for the assessment of multiple ecosystem services is proposed
as a basis for discussion and further development of a respective evaluation instrument. Using quantitative and

Demographic changes and the demands on agricultural landscapes: Refl ections on a new research topic

Peer-reviewed publication
Décembre, 2008

Demographic change suggests substantial effects on future societal demands on agricultural landscape use and thus on rural areas. Demographic change is thereby defined as both the decrease of the population and the shift in the age distribution („aging“) and in the spatial distribution („rural flight“ particularly of young people).

Sustainable landscape development and value rigidity: the Pirsig‘s monkey trap

Peer-reviewed publication
Mars, 2015

New broader, adaptable and accommodating sets of themes have been proposed to help to identify, understand and solve sustainability problems. However, how this knowledge will foster decisions that lead to more desirable outcomes and analyses necessary to transition to sustainability remains a critical theoretical and empirical question for basic and applied research. We argue that we are still underestimating the tendency to lock into certain patterns that come at the cost of the ability to adjust to new situations.

Estimating the value of a positive change in trout fly-fishing quality in the Rhodes trout fishery, Eastern Cape, South Africa

Peer-reviewed publication

Afrique

The Rhodes trout fishery, located in the North Eastern Cape, is one of South Africa’s premier fly-fishing destinations. The integrity of the fishery is, however, under threat due to various land-use practices, which could weaken its appeal as a tourist attraction. The aim of this study is to estimate the amount recreational users are willing to pay for a project to improve the trout habitat of waters managed by the Wild Trout Association (WTA) in this fishery in order to improve its fish population density by 100 per cent.

Do Flying Beetles Respond to Human-Dominated Landscapes as Complex Mosaics or Binary Patterns?

Peer-reviewed publication
Février, 2010

Understanding and measuring functional connectivity for animals with habitats that have been fragmented by human
activity requires that the biology and movement of the species be considered. We used least cost paths in GIS
to test hypotheses regarding how different species of longhorned beetles likely connect habitats with dispersal.
We predicted that there would be differences in the functional connectivity of landscapes depending on species
larval niche breadth, adult feeding habits, and the potential for use of non-forest habitats. For the species with very

Biorefineries: Relocating Biomass Refineries to the Rural Area

Peer-reviewed publication
Juillet, 2012

The field for application of biomass is rising. The demand for food and feeding stuff rises while at the same time energy, chemicals and other materials also need to be produced from biomass because of decreasing fossil resources. However, the biorefinery ideas and concepts can help to use the limited renewable raw materials more efficiently than today. With biorefineries, valuable products, such as platform chemicals, can be produced from agricultural feedstock, which can subsequently be further processed into a variety of substances by the chemical industry.

Analysis of physical expansion and sprawl growth factors of Sari city using Shannon and Heldern entropy models

Peer-reviewed publication
Février, 2015
Iran

Population growth and rapid urbanization growth in recent decades have not only led to unbalanced physical expansion of cities, but also contributed to growth and development of cities. The city of Sari in Iran, like many other cities is not immune from these changes. The city population has increased by 16 times over the last fifty years. Therefore, the increasing population growth has created uncontrolled physical expansion in the city.
