“…Indeed, natural and semi-natural ecosystems show edge effects (Fernàndez et al, 2002;Conceptión et al, 2012), due to the spatial heterogeneity in farming systems (Dick et al, 2014) and due to the spatial heterogeneity of climatic and market conditions (Mücher et al 2009;Chiron et al, 2013).…”

The connection between agriculture and environment is a central topic to the agricultural policy agenda and it has been the core of policy reforms. These linkages have been strengthened by the 2003 Common Agricultural Policy (CAP) Reform that has introduced a set of environmental rules as a condition to receive Single Farm Payments (SFP). Consequently, the provision of environmental goods is addressed by both CAP pillars I and II, respectively, with cross-compliance belonging to pillar I while the second axis Rural Development Program (RDP) measures belong to the pillar II. The aim of this paper is to analyse the provision of environmental goods provided by agricultural activities and the impact the Common Agricultural Policy has on such provision. This aim is pursued firstly by quantifying an environmental quality indicator based on the concept of High Nature Value (HNV) farmland and, secondly by testing Exploratory Spatial Data Analysis (ESDA) techniques and spatial econometric models as means to identify provision determinants that improve causality in spatially non-stationary data. The analysis highlights the relevance of spatial models in improving the quality of the estimation, while model results show that rural development program measures and income support payments have opposite effects. Results confirm the relevance of productive factor use and entrepreneurship in explaining differences on environmental quality provision.

“…Furthermore, ecotone research can be linked to landscape ecology topics such as edge penetration, edge effect, interior habitat, and ecological gradients (Ewers and Didham, 2006), as patches in fragmented landscape are spatially defined by their physical limits, or borders (Forman, 1995). Both biotic and abiotic properties of the patches are influenced by and subjected to spatial dynamics across these borders (Fernandez et al, 2002). Increasing fragmentation of landscape will also increase the importance of these dynamics within the created patches.…”

A b s t r a c t. Harmonious planning of agro-forestry landscapes plays a increasing role in building a social satisfaction flowing from the high quality of the environment on the rural areas. It is also a very good way to create a unique place identity of protected areas, rest areas etc. especially valuable regions. The objectives of the paper are: 1) elaboration the method of evaluation and mapping the physiognomic landscape composition on the rural areas with a high natural values; 2) testing this method on dominated by forests, peatbogs and arable lands the central part of the West Polesie UNESCO Biosphere Reserve (Eastern Poland); 3) formulation of guidelines on the design of landscape interiors and view openings composition, highlighting the unique features of West Polesie landscape and building a sense of the place identity; 4) to show the necessary to enshrine the values of physiognomic landscape composition in land use policy. In evaluation and mapping the landscape composition, a special attention was paid to the role of agro-forest ecotones. The results of the research part of the study as well as a guidelines on landscape design have been presented in the form of a map, study figures and a description.

“…One potential barrier to this type of research is lack of tools. Quantitative methods that can quantify and extrapolate multiple edge effects have been proposed [52,53,55], but these methods need to become more user-friendly to provide broader applications.…”

Edge effects are one of the most extensively studied ecological phenomena of the past 100 years. Despite the stillcommon perception that edge effects are overly complex and idiosyncratic, we do know a lot about the mechanisms that underlie them. A major review from 2004 described four fundamental mechanisms that cause most edge patterns. In general, altered resource distributions due to often-predictable gradients in the edge environment as well as access to multiple resources across edges accounts for the fundamental differences between habitat edges and interiors. However, altered species interactions near edges are another fundamental component of edge ecology and remain difficult to predict. Here, we follow up on that 2004 review and show that the same four mechanisms described there remain sufficient to explain most edge responses, but we highlight some new developments. Notably, we find that edge studies have widened to include many new habitat types, a more diverse taxa and broader regions of the world. Yet, even recent studies were often not designed to quantify critical metrics such as the depth or magnitude of edge influence. Further, sample sizes and study design continue to contribute to spurious variability and make comparing results difficult. These problems make extrapolation to larger scales problematic and a lack of effective tools for extrapolation complicate this goal even further. We offer suggestions on a set of best practices for designing edge studies and propose that future research should shift more towards extrapolation across landscapes.
