Public intervention in rural housing markets

This paper is a revised version of one presented to the Regional Science Association Conference, University of Leeds, September 1983.

The extent of rural poverty is largely hidden, yet mean rural incomes are lower than in urban areas. Equally, the differential between low incomes and high minimum house prices in rural areas not always acknowledged. This paper looks at the planning response to these problems against alternative approaches including discriminatory policies against second home owners in rural areas. The paper concludes by identifying a solution restricting private development and augmenting public‐sector provision in rural areas.     

Land development and employment creation on landed estates in the Northern Highlands

The landed estates may be divided into four groups according to land use and use intensity: crofting, sheep, sporting, mixed use. While sheep and mixed use estates have held sheep numbers constant, other estates have shown dramatic declines. All estates, and in particular sporting estates, have increased deer culls. Many sporting estates are supported by external private finance which makes land development unnecessary. Private enjoyment is an important ownership motivation on many estates. This, rather than lack of profitability or lack of finance, prevents development. However, significant employment creation can come only through extensive land developments beyond those on even the more productive estates. Such a strategy would require a development plan and a challenge to existing property rights.     

Integrated Ecological and Regional Planning in a Rapid-Growth Setting

Toronto is among the fastest-growing urban regions in North America. Regional efforts to preserve rural landscapes and remnant habitat have had variable success. In the 1990s, significant conflict emerged over proposals to build large housing developments on portions of the Oak Ridges Moraine, a 160-km stretch of environmentally sensitive land along the city’s northern edge. After years of planning conflict, Ontario’s provincial government created the Oak Ridges Moraine Conservation Plan, an Act of the Ontario Legislature. The Plan represents a dramatic change in Ontario’s approach to conservation planning. We examine the development and implementation of the Conservation Plan as an example of environmental planning policy in a complex urban setting. Data from interviews with policy actors, planning agency documents, and geospatial sources are used to construct an analysis and discussion of the Plan and its implementation. From a policy research perspective, the evolution and implementation of the Plan require analysis and monitoring to better understand how such approaches can best be implemented. The Conservation Plan marks a change in policy in Ontario, and the implementation process highlights challenges in putting conservation plans into practice.     

“Down in the forest something stirred”: issues raised by the Lyndhurst planning inquiry

The Planning Inquiry is used in Britain as a vehicle for resolving conflicts between energy developments and land use in areas of high ecological or amenity value. This is a report of one such inquiry; the Lyndhurst Inquiry which has been regarded as a test case of establishing oil and gas reserves against the importance of environmentally sensitive areas. The ultimate decision is seen as indicative of the complexity of issues involved.     

A better future for the uplands — a planning critique

The Countryside Commission's report A Better Future for the Uplands puts forward a new strategy for public intervention in the uplands of England and Wales. The aim of the report is to integrate rural policies and to promote higher environmental priorities in rural areas. This paper considers the degree to which the report is successful in planning to achieve these ends. The paper is specifically concerned with the planning methodology on which the report is based. The paper argues for an approach to rural planning which permits the consideration of more radical solutions to rural problems, along with the application of a more systematic planning methodology, in order to assist in the choice of an appropriate direction for planned change.     

Theory in practice: the anatomy of a borough plan

This paper focuses on the development plan activities of the London Boroughs and simply seeks to explain the relatively limited progress that has been made in the preparation and adoption of statutory local plans, by showing how production was constrained as local planners were caught up in the shifting ground of contemporary planning theory. The author suggests that uncertainty about the acceptable scope and content of local plans, at a time when planners were being encouraged to extend the emphasis of their work beyond the purely physical, led to serious problems as planners began to experiment with new approaches to local planning but failed to appreciate the operational implications of each approach.     

Ecological Conservation Through Aesthetic Landscape Planning: A Case Study of the Lower Wisconsin State Riverway

A consequence of expanding residential development into rural areas is the potential alteration of ecological communities. Certain novel land-use policies seek practical solutions by accommodating social needs for housing while conserving biodiversity. This study investigates whether regulations designed to protect the aesthetic characteristics of a river corridor simultaneously mitigate negative effects of development on avian biodiversity, despite the absence of explicit conservation objectives. Using housing data from the US Census (1990 and 2000) and the Audubon Christmas Bird Count (1987–2000), we examined changes in housing density, avian communities, and the relationship between these two variables in a location that has adopted aesthetic landscape planning, the Lower Wisconsin State Riverway. We found that overall species diversity increased in the Riverway, but remained constant in reference areas, although the relative increase in housing density in the two areas did not differ. We also found that omnivore populations decreased in the Riverway and increased in reference sites. On the whole, our study provides preliminary evidence that aesthetic landscape planning, such as employed in the Lower Wisconsin State Riverway, might constitute a politically viable approach to conserve ecological resources.     

Local plans and planning in England

Whilst the process of local plan preparation and adoption in England is far from complete, the commitment to the statutory planning process has not precluded the use of informal or non‐statutory material either in addition to or instead of statutory plans. This paper attempts to quantify the extent of non‐statutory local planning activity in England, and explores some of the advantages and disadvantages which an informal approach involves.     

Measuring and Incorporating Vulnerability into Conservation Planning

Conservation planning is the process of locating and designing conservation areas to promote the persistence of biodiversity in situ. To do this, conservation areas must be able to mitigate at least some of the proximate threats to biodiversity. Information on threatening processes and the relative vulnerability of areas and natural features to these processes is therefore crucial for effective conservation planning. However, measuring and incorporating vulnerability into conservation planning have been problematic. We develop a conceptual framework of the role of vulnerability assessments in conservation planning and propose a definition of vulnerability that incorporates three dimensions: exposure, intensity, and impact. We review and categorize methods for assessing the vulnerability of areas and the features they contain and identify the relative strengths and weaknesses of each broad approach. Our review highlights the need for further development and evaluation of approaches to assess vulnerability and for comparisons of their relative effectiveness.     

Integrating Human Impacts and Ecological Integrity into a Risk-Based Protocol for Conservation Planning

Conservation planning aims to protect biodiversity by sustainng the natural physical, chemical, and biological processes within representative ecosystems. Often data to measure these components are inadequate or unavailable. The impact of human activities on ecosystem processes complicates integrity assessments and might alter ecosystem organization at multiple spatial scales. Freshwater conservation targets, such as populations and communities, are influenced by both intrinsic aquatic properties and the surrounding landscape, and locally collected data might not accurately reflect potential impacts. We suggest that changes in five major biotic drivers—energy sources, physical habitat, flow regime, water quality, and biotic interactions—might be used as surrogates to inform conservation planners of the ecological integrity of freshwater ecosystems. Threats to freshwater systems might be evaluated based on their impact to these drivers to provide an overview of potential risk to conservation targets. We developed a risk-based protocol, the Ecological Risk Index (ERI), to identify watersheds with least/most risk to conservation targets. Our protocol combines risk-based components, specifically the frequency and severity of human-induced stressors, with biotic drivers and mappable land- and water-use data to provide a summary of relative risk to watersheds. We illustrate application of our protocol with a case study of the upper Tennessee River basin, USA. Differences in risk patterns among the major drainages in the basin reflect dominant land uses, such as mining and agriculture. A principal components analysis showed that localized, moderately severe threats accounted for most of the threat composition differences among our watersheds. We also found that the relative importance of threats is sensitive to the spatial grain of the analysis. Our case study demonstrates that the ERI is useful for evaluating the frequency and severity of ecosystemwide risk, which can inform local and regional conservation planning.     

The British road to post war planning: the forty‐year journey to the 1947 town & country planning act

This paper analyses the currents which gave rise to the 1947 Town & Country Planning Act. It describes the main statutory events in the first half of the 20th century and considers the progress made in implementing the legislation. It is argued that, while the 1947 Act was a major advance on what went before, it is not a significant departure.     

Using a computerized land-use planning package with the FAO framework for land evaluation

The Food and Agriculture Organization's (FAO) land evaluation methodology provides a procedure for assessing the suitability of land units within a study area for different land uses. This article describes the use of theLuplan computerized land-use planning package to provide an explicit means to select the land use for each land unit which best satisfies defined policies. The use of the package is demonstrated in a study that allocated multiple use activities within a native forest.     

Housing association and local authority provision in rural housing markets: a Mid‐Wales case study

Over the last decade or so, rural housing problems in Britain have become an important focus of attention both for researchers and planners. Inaccessibility to adequate housing is a significant component of the more all‐embracing problems of rural deprivation. The rented sector is of particular relevance to the amelioration of these problems, but the supply has been increasingly restricted both in the private and in the public sector. Great stress has therefore been laid on the ability of housing associations to provide rented sector housing. This paper investigates the work of one particular housing association in Mid‐Wales — Cymdeithas Tai Dyffryn Teifi (CTDT) and assesses the degree of complementarity achieved with housing provision by the local councils operating in the same rural locality. The particular areas of effectiveness of a housing association in this context are thereby evaluated.     

The town and country planning act 1947

The 1947 Town & Country Planning Act is regarded as the statutory foundation of physical planning in post‐war Britain. This paper looks at the Act in context and assesses its effectiveness from the vantage point of forty years since its implementation.

“The way forward”

The paper looks at the progress in the planning process since 1947 and the scale of physical change that has taken place in the intervening years. Lessons of this experience form the basis for looking forward to how the process is changing now, and what trends for the immediate future might be identified.     

Simplified planning zones — a reaction to the proposals

The Government has recently published Lifting the Burden which includes the proposed legislation on Simplified Planning Zones. This paper, based on recently undertaken research, specifically considers the reaction of a sample of local authorities and private agencies to the proposals.     

Testing the Use of a Land Cover Map for Habitat Ranking in Boreal Forests

Habitat loss and modification is one of the major threats to biodiversity and the preservation of conservation values. We use the term conservation value to mean the benefit of nature or habitats for species. The importance of identifying and preserving conservation values has increased with the decline in biodiversity and the adoption of more stringent environmental legislation. In this study, conservation values were considered in the context of land-use planning and the rapidly increasing demand for more accurate methods of predicting and identifying these values. We used a k-nearest neighbor interpreted satellite (Landsat TM) image classified in 61 classes to assess sites with potential conservation values at the regional and landscape planning scale. Classification was made at the National Land Survey of Finland for main tree species, timber volume, land-use type, and soil on the basis of spectral reflectance in satellite image together with broad numerical reference data. We used the number and rarity of vascular plant species observed in the field as indicators for potential conservation values. We assumed that significant differences in the species richness, rarity, or composition of flora among the classes interpreted in the satellite image would also mean a difference in conservation values among these classes. We found significant differences in species richness among the original satellite image classes. Many of the classes examined could be distinguished by the number of plant species. Species composition also differed correspondingly. Rare species were most abundant in old spruce forests (>200 m³/ha), raising the position of such forests in the ranking of categories according to conservation values. The original satellite image classification was correct for 70% of the sites studied. We concluded that interpreted satellite data can serve as a useful source for evaluating habitat categories on the basis of plant species richness and rarity. Recategorization of original satellite image classification into such new conservation value categories is challenging because of the variation in species composition among the new categories. However, it does not represent a major problem for the purposes of early-stage land-use planning. Benefits of interpreted satellite image recategorization as a rapid conservation value assessment tool for land-use planners would be great.

Landform Classification for Land Use Planning in Developed Areas: An Example in Segovia Province (Central Spain)

Landform-based physiographic maps, also called land systems inventories, have been widely and successfully used in undeveloped/rural areas in several locations, such as Australia, the western United States, Canada, and the British ex-colonies. This paper presents a case study of their application in a developed semi-urban/suburban area (Segovia, Spain) for land use planning purposes. The paper focuses in the information transfer process, showing how land use decision-makers, such as governments, planners, town managers, etc., can use the information developed from these maps to assist them. The paper also addresses several issues important to the development and use of this information, such as the goals of modern physiography, the types of landform-based mapping products, the problem of data management in developed areas, and the distinctions among data, interpretations, and decisions.
