Anthropogenic and topographic correlates of natural vegetation cover within agricultural landscape mosaics in Turkey

Natural vegetation enhances the value of agricultural landscapes for people and wildlife. However, the role of anthropogenic versus topographic factors in driving the extent of natural vegetation cover within agricultural lands at large spatial scales remains unexplored. I assessed the influence of anthropogenic and topographic variables on the extent of agricultural mosaics with high natural vegetation cover in the country of Turkey where a large extent of natural and semi-natural vegetation is maintained by traditional agriculture. GIS layers depicting human land use, elevation, slope, roads and population data were obtained and summarized at two spatial scales, within provinces and for 100 km² grid cells covering the country’s entire agricultural land area. Average farm size was also obtained at province level. Hierarchical Partitioning was conducted to determine the independent effect of anthropogenic and topographic variables on the variation in agriculture with high natural vegetation. Slope had the largest independent effect on the variation in the proportion of agricultural mosaic with high natural vegetation cover. The extent of agricultural and settlement area also explained much of the variation in natural vegetation across both grid cells and provinces. The proportion of natural vegetation increased as human population and road density decreased across grid cells and as average farm size decreased across provinces. These results suggest that while topography is the primary driver of natural vegetation cover within agricultural mosaics in Turkey, the pressures associated with urban development and agricultural industrialization may also influence the cultural and wildlife value of agricultural landscapes.     

Addressing the social landscape dimensions: The need for reconciling cross scale assessments for capturing Cultural Ecosystem Services (CES)

This special issue integrates eleven papers focussing on indicators able to convey the multiple expectations that society has concerning agricultural land. As scale issues have been so far overlooked within this research topic, a particular focus of this themed issue is to highlight the need for reconciling assessments across scales. The shared purpose of the contributions is to examine how the multiple societal expectations concerning agrarian landscapes might be incorporated into land use policy at different governance levels.A core set of these papers were presented in the symposium “Linking social indicators across scales”, to the European Congress of the International Association of Landscape Ecology (IALE) in September 2013 in Manchester, UK. This symposium was organized to create the time and space for a discussion on the issues of scale when capturing societal preferences concerning agrarian landscapes. While the landscape scale was specifically addressed by four papers, seven papers examined broader geographic units in addition to up-scaling and downscaling issues.     

Engaging Australian small-scale lifestyle landowners in natural resource management programmes – Perceptions,past experiences and policy implications

This study explores Australian small-scale rural lifestyle landowners’ perceptions of and experiences with natural resource management (NRM) extension and incentive programmes and discusses means to better-match such programmes to these landowners’ NRM interests, assistance needs and delivery preferences. Data was collected from seventeen in-depth qualitative case-studies of small-acreage landholders located in the Noosa hinterland in south-east Queensland. These landholders indicated a high need for expert advice, labour and other resource assistance to achieve their property management objectives. They had, however, a low-level of awareness and understanding of available programmes (particularly incentive schemes) that could provide some of their needed support. Other key barriers to the landholders’ participation in these programmes were aversions to support providers, a perceived unsuitability of properties or irrelevance of particular incentive programmes, and concerns about programme application procedures or property-rights and value-related implications of engagement. Increased NRM engagement among small-scale lifestyle landowners may be achievable through amendments to existing support programmes and better communication of these programmes. The design and delivery of appropriate measures and messages may require collaborative partnerships, with knowledgeable and influential ‘go-to’ landowners and peer-mentoring networks playing a critical role. In many cases, conservation-focused incentive programmes may need to facilitate cooperative NRM among groups of adjoining micro-scale lifestyle landowners and allow greater flexibility in the length and allowable land and forest management practices of contractual agreements. Moreover, small-scale lifestyle landowners have much interest in and need for support to integrate multi-purpose agroforestry systems with other environmental and aesthetic property management goals. Workshops, follow-up field-days on participating properties, free one-on-one on-property advice, and NRM guides that include detailed case-study accounts of landowner experiences are important means of communicating the availability, administrative requirements and benefits of support programmes to small-scale lifestyle landowners.     

Willingness to Pay for Rural Landscape Improvements: Combining Mixed Logit and Random‐Effects Models

This paper reports the findings from a discrete‐choice experiment designed to estimate the economic benefits associated with rural landscape improvements in Ireland. Using a mixed logit model, the panel nature of the dataset is exploited to retrieve willingness‐to‐pay values for every individual in the sample. This departs from customary approaches in which the willingness‐to‐pay estimates are normally expressed as measures of central tendency of an a priori distribution. Random‐effects models for panel data are subsequently used to identify the determinants of the individual‐specific willingness‐to‐pay estimates. In comparison with the standard methods used to incorporate individual‐specific variables into the analysis of discrete‐choice experiments, the analytical approach outlined in this paper is shown to add considerable explanatory power to the welfare estimates.     

Recreation and Tourism in Areas of Outstanding Natural Beauty: Key Influences on the Policymaking Process

This paper reports on a study completed in 2000 into the policymaking process for recreation and tourism in AONBs across England and Wales, with particular focus on the key influencing role of communication within this process. A number of practical measures, which might aid AONB communication and collaboration for policy development and implementation in the future, are derived from the research. In addition, the findings of the study lend weight to calls (current at the time of the research) for enhanced powers and funding for AONBs, particularly in respect of recreation and tourism provision.     

The crucial epoch: Essential knowledge for living in a world in transformation

Mankind is entering the most crucial epoch in its history. The global economic and socio-technical industrial system in place since World War II is coming to a close. What takes its place is up to mankind to decide. Drawing on current work in non-equilibrium thermodynamics, evolutionary biology, cybernetics and systems science theory, the author identifies crucial bifurcation epochs in human history where new biological species and human societies have evolved from the old, replacing themselves with better adapted successors. Although scientists speak of bifurcation as essentially random, human societies are able to exercise foresight and take purposeful action. At this critical juncture, as post-industrial civilization comes to an end, this is the choice that humanity is morally bound to exercise.     

The institutional drivers of sustainable landscapes: a case study of the ‘Mayan Zone’ in Quintana Roo, Mexico

Research on the dynamics of tropical forest land use and cover change (LUCC) has focused on the three scenarios: (1) deforestation/degradation; (2) settled, degraded areas in recovery, and (3) sparsely settled, expansive, intact forest. Through examination of a central Quintana Roo, Mexico case study we propose a fourth scenario of a ‘sustainable landscape’: an inhabited, productively used, forested landscape that nonetheless shows little change or net gains in forest cover over the last 25 years. We use Landsat images to demonstrate a low incidence of net deforestation, 0.01% for the 1984–2000 period, the lowest recorded deforestation rate for southeastern Mexico. Institutional innovations such as an agrarian reform process that established large common property forests for non-timber forest product extraction, and later innovations such as sustainable forest management institutions have driven the outcome of low net deforestation, added to multiple organizational processes that promote sustainable land use.     

What comes after the welfare state?: A post-welfare development path for the UK

One vision of post-industrial society projects a sane, humane, ecological future. Achievement of this requires societal transformation of almost unprecedented dimensions. This paper offers a preliminary exploration of how changing directions to this kind of future would affect social welfare and social services in the UK. Current community activities which may help accelerate change in local futures are outlined.     

Governance of ecosystem services trade-offs in peri-urban landscapes

Peri-urban landscapes (PULs) are specific transitional forms of urban landscapes undergoing dynamic land-use changes. PULs’ transformations are driven by close and significant influence of an urban core, cross-administrative boundary character, and diversity of governance actors. PULs have significant potential to provide ES and respond to the urban and peri-urban demand for ES, but they are also particular contexts where significant and different ES trade-offs can occur. Majority of existing forms of governance are not able to deal and address such trade-offs, which thus call for more innovative and effective governance approaches and mechanisms, aimed at achieving ES synergies and reducing ES conflicts.This paper discusses the characteristics of PULs in the context of governance questions related to the management of ES trade-offs in the urban peripheries. The drivers of ES trade-offs are presented and different trade-off relationships between and within the main ES types are analyzed. The paper drafts a way forward from the current state-of-the-art related to governance of peri-urban ES trade-offs by providing recommendations for more effective governance that would address these trade-offs. Due to the very dynamic character of PULs, it is difficult to manage land-use changes and ES trade-offs. Hence, the governance approaches need to be adaptive and integrative at multiple levels, while engaging diverse actors to balance ES trade-offs that have mixed urban and rural character.
