Designing Whole Landscapes

A whole-landscape approach is critical to ensuring conservation and enhancement of biodiversity in farmed landscapes. Although existing agri-environmental schemes are constrained by property boundaries and voluntary take up, the potential for adopting a whole-landscape approach to planned countryside management is currently favoured by a number of factors. These include economic uncertainty in some agricultural sectors; the introduction of a reformulated rural development policy; increased understanding of relationships between biodiversity and management; and the introduction of Geographical Information Systems (GIS) technology that allows future landscapes to be visualized by stakeholders. Ecological and socio-economic aspects of whole-landscape planning in a study covering 31 neighbouring farms in west Oxfordshire are reported. A baseline was first compiled that included information on: property boundaries; land cover; relationships between hedge and field margin management and key taxa; and farmer socio-economics and attitudes towards agri-environmental measures, conservation and sustainable agriculture. Future scenarios of integrated wholelandscape management were then developed, designed to deliver amenity, environmental and biodiversity benefits. These scenarios were presented and interpreted to farmers and conservation and amenity stakeholders with the aid of GIS-based maps and three-dimensional virtual reality visualizations. Farmers' responses are reported and the potential for implementing whole-landscape planning is discussed .

Landscape Dynamics and the Management of Change

Change in economy and society is directly reflected in the character of landscapes, both in terms of their form and function and the landscape planning and management challenges which they present. The phenomenon of landscape dynamics within post-industrial society is considered and the development of a connection between the drivers of landscape change and the management response is sought. Two key drivers of landscape change are proposed - 'obsolescence' and 'dysfunction' - and these in turn are related to a management matrix bounded by axes of condition and character of landscape. It is suggested that the definition of these relationships helps to substantiate and more clearly define the tasks of landscape planning, design and management in the United Kingdom.

Is Managed Recreational Use Compatible with Effective Habitat and Wildlife Occurrence in Urban Open Space Corridor Systems?

The extent to which urban open space corridors meet recreational, habitat and wildlife needs is highly dependent on the degree to which the interactive effects of these uses are identified and incorporated into planning, design and management decisions. For managers who aim to enhance compatibility between people and wildlife, the challenge is to bridge the gap between established practice and a more multi-functional approach. Ultimately the aim should be to put in place an enlightened and sympathetic management regime that supports indigenous biodiversity maintainable at an acceptable cost and is compatible with providing sufficient access to cater for a wide range of recreational activities. Principles relating to site evaluation and corridor management are discussed in the context of a case study in Singapore.     

OBSERVATION AND REPRESENTATION: ON RECOGNITION AND EXPRESSION OF NATURAL SITES IN LANDSCAPE ARCHITECTURE

In the education of Landscape Architecture, the way we view and depict a natural site is defined by the way we observe and express it. This paper starts with a comparison between the perspective and approach of traditional painting types (the realistic sketch, design sketch, and landscape painting) and those in Landscape Architecture. All of them involve observation (viewing) and expression (drawing) of natural beings and phenomena, where traditional paintings are in the pursuit of honest depiction of the forms or shapes. While in Landscape Architecture it emphasizes understanding and representing the evolutions and the complicated intrinsic relations of the authentic sites — in other words, to represent the nature of reality. To be on-site, the use of body movement, and the evolutions and correlations of natural beings are the three most important principles to the observation and representation in Landscape Architecture. Combining with two cases in teaching and practice, this paper elaborates how to develop abstract forms and design concepts from the observation of authentic sites and how the trans-scaled reflection on the correlations about the sites can inspire a site-scaled design, providing references for the education and practice of Landscape Architecture in China.

Environmental affordances and children’s needs: Insights from child-friendly community streets in China

With rapid urbanization in China, an increasing building density has squeezed the urban public space. Community streets are occupied by motor vehicles or other functions, and can no longer sufficiently support children to carry out safe and independent activities. As an important space for children’s daily natural contact and social activities, the lack of the spatial function of streets results in a decline in children’s subjective initiative and social abilities. The United Nations has stressed the importance of community as the basic unit of space for children’s daily activities in building child friendly cities. It is urgent to reshape child-friendly community streets and support children’s healthy growth. Integrating previous research results on affordance theory and design, children’s growth and environment, and street-game spaces, this study focuses on investigating 23 community streets in four residential communities in Nanjing through questionnaires, interviews, observations, and other methods. Then, from the perspective of cognitive affordance, functional affordance, and social affordance, it analyzes the behavioral possibilities provided by the environment and the needs of the children-user group. Finally, from the perspectives of openness and security, preference and diversity, positive and negative, and reality and potential, it proposes a method to assess the existing environment. This study aims to extract the significant characteristics of the built environment that effectively support and promote children’s outdoors activities, and explore the design strategy of improving street space sharing through optimizing space elements and structure at the medium and micro levels, so as to respond to multiple goals including livable city development from the perspective of child friendliness. This study also tries to change the logical way of design thinking and provide an eco-psychological perspective on how to build a child-friendly community.

Shaken,shrinking, hot,impoverished and informal: Emerging research agendas in planning

This is the second of two special issues in Progress in Planning exploring emerging research agendas in planning. It brings together scholars from diverse schools working on new areas of research and application in urban design and planning. Emergent research agendas include both novel areas of research and important shifts in the direction of a research area. The challenge for planning schools is to reflect critically on these changes and develop long-term research agendas that can better position our field in society and academia, and provide a basis from which to assess our academic programmes. The chapters in this issue display the different scales and fields of planning, including planning for: disaster recovery; climate change, especially opportunities for mitigation; shrinking cities in the First World; and rapidly urbanising informal and impoverished cities in the global South. At the same time, the chapters identify research areas that respond to major social and environmental changes. Olshansky and Chang highlight the increasing losses from catastrophic disasters, and address the need for disaster recovery planning. Wheeler, Randolph and London focus on climate change, and, noting the urgency of action now, their research agenda emphasises opportunities for planners to develop research and policies to reduce greenhouse gas emissions. Hollander, Pallagst, Schwarz and Popper look at increasing economic and population trends in many First World cities that result in city ‘shrinkage’. They present new opportunities for improving cities’ green space networks and natural features, and for research. The trebling of urban population in African cities by 2050, in conditions of poverty and informality, is the major trend driving Parnell, Pietriese and Watson's chapter. They present an agenda for new planning theories and for supporting empirical research to address the actual conditions of African cities.
