Is Oregon's land use planning program conserving forest and farm land? A review of the evidence

Planners have long been interested in understanding ways in which land use planning approaches play out on the ground and planning scholars have approached the task of evaluating such effects using a variety of methods. Oregon, in particular, has been the focus of numerous studies owing to its early-adopted and widely recognized statewide approach to farm and forest land protection and recent experiment with relaxation of that approach in 2004 with the passage of ballot Measure 37. In this paper we review research-based evidence regarding the forest and farm land conservation effects of Oregon land use planning. We document the evolution of methods used in evaluating state land use planning program performance, including trend analysis, indicator analysis, empirical models, and analysis of indirect effects on the economic viability of forestry and farming. We also draw on data documenting Measure 37 claims to consider the degree to which Measure 37 might have altered land use and development trends had its impacts not been tempered by a subsequent ballot measure – Measure 49. Finally, we provide a synthesis of the current state of knowledge and suggest opportunities for future research. Common to nearly all of the studies we reviewed was an acknowledgement of the difficulty in establishing causal relationships between land use planning and land use change given the many exogenous and endogenous factors involved. Despite these difficulties, we conclude that sufficient evidence does exist to suggest that Oregon's land use planning program is contributing a measurable degree of protection to forest and farm land in the state.     

Zionism and agricultural land: National narratives,environmental objectives,and land policy in Israel

The 1990s saw two different and even contradictory trends in Israel. On the one hand, there was a substantial increase in environmental awareness, on the part of both the general public and decision-makers, that led to a change in the land use planning policy at the national level. On the other hand, the Israel Lands Council (ILC), the body empowered by law to shape the national land policy, made a series of decisions that severely violated the principle of preserving agricultural land and led to massive conversion of agricultural land and open space for commercial, industrial, and residential development. Thus the national land policy became incompatible with the land use planning policy and the rise in environmental awareness it reflected.

Governing Suburbia through regionalized land-use planning? Experiences from the Greater Frankfurt region

This paper explores the case of peripheral settlement growth in the Greater Frankfurt (Main) region within current debates on global suburbanization. Within Germany’s sophisticated spatial planning regime, Greater Frankfurt’s system of regionalized land-use planning marks an ambitious initiative to contain urban sprawl. Nonetheless, expansive peripheral settlement growth, and socio-spatial polarization remain distinct characteristics of the booming region. Analyzing state regulation vis-à-vis dynamics of capitalist urbanization and private authoritarianism, we decipher the complex governance arrangements producing this, at first sight, contradictory simultaneity. We uncover the rationales of local growth politics of autonomous municipalities and the region’s multiplied institutional fragmentation that undermine planning ambitions to contain suburban growth. We conclude by critically assessing the political economies of suburbanization in Greater Frankfurt and point to prospects for regional reform.

How do centrality,population growth and urban sprawl impact farmland conversion in Norway?

A strong link has been observed between urbanization processes and conversions of farmland to built-up land. Most previous research has addressed such conversion of farmland in relation to the expansion of larger cities. However, broader analysis of both rural and central areas is needed to increase the empirical basis for these claims. Based on GIS analysis of farmland conversions, this paper aims to expand our understanding of how urban sprawl affects conversion of farmland. We find that most farmland in Norway is converted to built-up areas in relation to existing urban settlement areas. In line with population growth, urban areas in the most central municipalities experience the most significant urban sprawl and loss of farmland. Moreover, the remaining farmland is located in the same areas that already have converted the most. These areas also experience significant pressure for continued land take. Assuming current trends continue, future urban sprawl will pose great challenges for the preservation of farmland in land-use planning. New research and policies are required to handle these challenges more effectively.     

Owned or rented—does it matter? Agricultural land use change within farm properties,case studies from Norway

In Norway and many other countries agriculture has moved toward less, but bigger farms. Total agricultural area has not been much affected mainly due to land tenancy. In this study we used aerial photographs to map land use and land cover in agricultural areas at present and in the mid-sixties. Three study sites were chosen, representing areas of differences with respect to drivers of change and possible differences in their landscape outcome. Maps from the two periods were used to produce transition matrices for the three areas as well as within each farm property. Our main finding on acreage change is that fully cultivated land increases and pastures decreases. A novel feature in our study is that we also include land use changes within single properties. In all three places a large share of the fully cultivated land in the sixties remains fully cultivated land irrespectively of whether the land is in use by its owner or is rented. When we looked at increases of fully cultivated land, the results are mixed. In the less favorable region, ownership to land versus rented land helps explain the variation in gain of fully cultivated land as well as maintained total agricultural area. However, in the case study from the grain region, whether a farm property today is in use as own land or rented, do not help explain the variation in changes within the data sample of farm properties larger than one hectare.

Patterns of development and conservation in agricultural lands—The case of the Tel Aviv metropolitan region 1990–2000

Until the 1990s Israel was implementing a strict agricultural land preservation policy program, rooted in Zionist ideology. This was changed when shifts in Israeli planning and land policy towards the end of the 20th century brought about accelerated growth and sprawling development in agricultural lands at the urban–rural fringe, particularly in the Tel Aviv metropolitan region (TMR). In this article we describe the background for policy shifts and the resulting impact on metropolitan growth, and then proceed to identify patterns of development in former agricultural lands and their impact on conservation, based on a study of statutory land use plans converting agricultural land to built-up uses within the TMR. It was found that most of the plans were converting large tracts of agricultural land to residential uses, characterized by low-density suburban-type family housing, thus reducing considerably the spatial conservation potential. In addition, only relative small portions of land were conserved as public open space within plans’ boundaries, and even then only about half of that was actually effective for active open space uses.

SEA making inroads in land-use planning in Brazil: The case of the Extreme South of Bahia with forestry and biofuels

In Brazil, incorporating the environmental dimension to the planning process is a challenging process. Planning has historically been carried without considering environmental protection concerns. The country's large development projects have engendered a discussion on the feasibility of these works given the conflicts with environmental policies. The strategic environmental assessment (SEA) is a tool that has the potential to integrate the sectoral, territorial and environmental perspectives to promote sustainable development, as shown by international experience. Its use has not yet been regulated in Brazil, only been voluntary initiatives, both public and private, have been implemented. This paper presents the structure and results of the SEA of the plans to expand silviculture of eucalyptus and biofuels in the Extreme South Region of Bahia state, in the Brazilian Northeast, in a context of sectoral planning dissociated from government guidelines for land use policy and environmental protection. It portrays a practical case of methodological proposal for the use of socio-environmental criteria to establish limits for land occupation by monocultures, for each of the municipalities of the study region, according to their specific climate, soil, relief and environmental preservation characteristics. Various alternatives were identified to ensure areas with greater productivity for small family farming and areas with potential for preservation. SEA helped to a better understanding of the effects of the expansion of the planting areas in each alternative, which was essential to help all stakeholders visualize the consequences of their strategies. Consequently, as results the SEA outlined a series of guidelines and restrictions for the various levels of government and the production sector. For instance, SEA suggested for Federal, State and Municipality governments that areas with better soil and climate conditions could be reserved for public policies to incentive the diversification of the uses of the territory, such as food production. SEA also suggests the adoption of incentive programs to establish multiple-use forests. The SEA recommended that the state government integrate its program for strengthening family agriculture with land-use planning criteria, based on cooperative systems The methodology employed has evidences to be replicable in other regions of Brazil and in developing countries.

The role of spatial planning in coastal management—A case study of Tuticorin coast (India)

The focus of coastal management in recent years has shifted from a sectoral plan to a holistic and integrated one. A key component of this integrated plan is spatial planning. This paper serves to highlight the role of spatial planning in coastal management by making use of a study done for the Tuticorin coast in India. A quantification of the land use/land cover changes in this region was studied along with the existing laws and policies governing the Indian coast with particular reference to Tuticorin, to determine their influence/impact on coastal land use/land cover. The results of the study show the disparity that exists between current land use practices and the laws that have been enforced to safeguard the coast. This can be overcome by means of implementing a more stable management plan that incorporates the spatial aspects of this coast, which has been presented.     

Urban spill over vs. local urban sprawl: Entangling land-use regulations in the urban growth of China's megacities

Rather than a bad case of urban sprawl, the physical expansion of China's megacities may be viewed as a combination of ‘urban spill over’ and ‘local urban sprawl’. This paper reviews land use regulations in their institutional context and argues that conflicts in land use regulation are related to ideologies of land ownership and embedded in different planning doctrines. These hypotheses are investigated with special reference to Guangzhou, the capital of Guangdong Province in southern China. The evidence suggests that entangled land use regulations for “urban” and “rural” land have imposed serious constraints on urban growth, while the contradictions of different policies and regulations in the use of rural lands for urban construction have led to intensive and unhealthy competition among stakeholders. As a result, not only have the costs of land conversion from rural to urban uses increased, but the spatial development of Guangzhou has been distorted. The implications of these failures for future policy are discussed with emphasis on the reform of the land use regulation system.

Voters’ Acceptance of Land Use Policy Measures: A Two-Level Analysis

Sustainable spatial planning has become increasingly important during the last decades. Politics tries to counter land use related challenges such as urban sprawl by the implementation of policy measures. In a direct democracy, the implementation of policy measures requires citizens’ acceptance. This paper examines determinants of voters’ policy measure acceptance in the area of spatial planning. The study analyses 18 popular votes on spatial planning measures between 1984 and 2008 in Switzerland. A Bayesian multilevel modelling method is used to estimate both determinants at the individual level as well as the contextual level. Results show that the main individual factor for voters in Switzerland to accept spatial planning measures in a broad sense are the party affiliations of voters. Another important factor for the voting decision is being a homeowner. In contrast, whether voters live in urban or rural areas does not influence such voting decisions. At the contextual level, policy measures which contain incentive and market-based instruments have a higher probability to be accepted than bans and rules. Moreover, the degree of organisational capacity and conflict capability of interests concerned seem to influence democratic acceptance of spatial planning measures.     

Forest and agricultural land change in the Carpathian region—A meta-analysis of long-term patterns and drivers of change

Humans have altered land cover for centuries, and land-cover change is a main component of global change. Land use transition trajectories, such as the forest transition theory (i.e. switch from deforestation to stable or increasing forest cover), relate long term changes in land use to gradual changes in underlying drivers, such as economic development, demographic change, and urbanization. However, because only few studies examined land change over centuries, it is not clear how land cover changes during very long time-periods which are punctuated by shifts in socio-economics and policies, such as wars. Our goal here was to examine broad land change patterns and processes, and their main driving forces in Central and Eastern Europe during distinct periods of the past 250 years. We conducted a meta-analysis of 66 publications describing 102 case study locations and quantified the main forest and agricultural changes in the Carpathian region since the 18th century. These studies captured gradual changes since the peak of the Austro-Hungarian Empire up to the accession to the European Union of most of the formerly socialist countries in the study region. Agricultural land-use increased during the Austro-Hungarian Empire in 70% of the case studies, but dropped sharply during and especially after the collapse of the Socialism (over 70% of the cases). The highest rates of abandonment occurred between 1990 and 2000. The Carpathian region experienced forest transition during the Interwar period (93% of the cases), and the forest expansion trend persisted after the collapse of Socialism (70% of the cases). In terms of the drivers, institutional and economic factors were most influential in shaping deforestation and agricultural expansion, while socio-demographics and institutional shifts were the key drivers of land abandonment. Our study highlights the drastic effects that socio-economic and institutional changes can have on land-use and land-cover change, and the value of longitudinal studies of land change to uncover these effects.
