    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).

    To discriminate between the contributions of ecosystems and the human subsidies to agricultural systems,
    we propose using an additional terminology to bring clarification into the controversial discussion about i)
    ecosystems versus agrosystems and ii) ecosystem services versus agrosystem services. A literature review
    revealed that with the exception of some very recent publications, this has not yet been sufficiently
    reflected, neither within the scientific nor in the policy discussion. The question remains whether to spoil

    European landscapes have featured considerable changes towards intensification and marginalisation.
    These major trends are expected to continue in the future. Besides, the cultivation of bioenergy crops has
    become an important factor in agricultural land use. A thorough understanding of land-use processes for
    management purposes is needed. In this study, the spatial and temporal pattern of agricultural land use
    and land-use change was classified at the scale of municipalities from 2005 to 2010. The study region was

    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 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.

    The impairment of landscapes is a concern constantly raised against wind energy developments in Germany
    as in other countries. Often, landscapes or landscape types are treated in the literature as essentialist or
    at least as uncontested categories. We analyse two examples of local controversies about wind energy, in
    which “landscape” is employed by supporters and opponents alike, from a poststructuralist and discourse
    theoretical angle. The aim is to identify and compare landscape constructs produced in the micro discourses

    This study aims at presenting a conceptual model for landscape management in the Himalayan region of India,
    using quantitative/mathematical approach. Keeping in view the requirement, (based on fifteen years empirical
    field work in the Himalayan region and as well as literature survey) the MODAM (Multiple Objectives Decision
    Support Tools for Landscape Management) model along with linear programming approach was adopted with a
    view to presenting additional methodological perspectives on interdisciplinary landscape research. The work has

    Inadequacies in the indication of cultural ecosystem services (CES) are a hindrance in assessing their
    comprehensive impacts on human wellbeing. Similarly, uncertainties about the quantity and quality of
    CES, in real time and space, have hampered the ability of resource managers to precisely take responsive
    management actions. The aim of the study is to demonstrate, how CES indicators can be identified and
    qualified in order to link CES to human wellbeing, and to integrate them into the ‘ecosystem services cascade’

    The scenic quality of a landscape is a natural resource that is to be preserved according to German and international law. One important indicator for the evaluation of this value is the structural diversity of the landscape. Although Landscape Metrics (LM) represent a well-known instrument for the quantification of landscape patterns, they are hardly used in applied landscape and environmental planning. This study shows possibilities for the integration of LM into a commonly used method to assess scenic quality by the example of a Landscape Structure Plan.
