Urbanization strategies, rural development and land use changes in China: A multiple-level integrated assessment

This paper links urbanization strategies to changes in land use and associated impacts on rural communities and agro-ecosystems in a rural area of China. Energy, monetary and human time variables as well as information on environmental pressures, have been combined to compare different typologies of households and the metabolism of different patterns of land use from an integrated perspective. The results show that urbanization strategies, aimed at shifting the current land use and at displacing the local population, while increasing the economic efficiency is also associated with an increase in fossil energy consumption and environmental pressure, as well as a reduction of the multifunctional characteristic of the area under investigation. Based on these findings the paper also offers a critical discussion of the Chinese rural development policy arguing that the multifunctionality of rural areas should be taken into account by Chinese policy-makers and planners as a viable strategy to achieve rural development targets.     

Land use policy in China: Introduction

This themed issue of Land Use Policy builds mainly on papers presented at an international conference on ‘Land Use Issues and Policy in China under Rapid Rural and Urban Transformation’, convened by the Chinese Academy of Sciences in Beijing, China, in October 2012. The conference set out to share and promote new scientific findings from a range of disciplines that advance research on land use policy in China. The contributions to this themed issue provide conceptual–theoretical and empirical takes on the topic, around four main areas of interest to both researchers and policymakers: nation-wide land use issues, the Sloping Land Conversion Program, land engineering and land use, and land use transitions. Various land use issues have been associated with rapid urban–rural transformations in China, giving rise to formulation of new policies directly affecting land use. However, these have contributed to new land use problems due to the nature of the policies and the difficulties in policy implementation constrained by the special ‘dual-track’ structure of urban–rural development in China. In view of this, this themed edition makes a compelling call for more systematic research into the making and implementation of China's land use policy. It also emphasizes the challenges for further research on land use policy in China.     

Potential hazards of land policy: Conservation,rural development and fire use in the Brazilian Amazon

With growing awareness of fire hazard as an environmental threat within tropical rainforests, the state of Brazil initiated a set of fire control policies aimed at monitoring and ameliorating fire hazard in the Amazon region. These policies were developed in the aftermath of large-scale fire events and reflect a conservationist discourse that responded to internal as well as international environmental concerns. In doing so, the policies have framed the “fire problem” around those who use fire in their land use practices, in particular small-scale agriculturalists. Yet, land policy in general has repeatedly failed to address the institutional arrangements which compel small-scale farmers to use fire in their agricultural practices and the underlying development processes that have made the landscape more vulnerable to accidental spread of fire. Using regional level data on small-scale farmers, I suggest that the conservation oriented approach of fire policy may not be enough to curtail accidental fire events and instead that the fire issue needs to be positioned within rural development as well.     

Cultivated land conversion and potential agricultural productivity in China

In China there is a growing debate on the role of cultivated land conversion on food security. This paper uses satellite images to examine the changes of the area of cultivated land and its potential agricultural productivity in China. We find that between 1986 and 2000 China recorded a net increase of cultivated land (+1.9%), which almost offset the decrease in average potential productivity, or bioproductivity (−2.2%). Therefore, we conclude that conversion of cultivated land has not hurt China's national food security. We also argue that more recent change in cultivated area likely has had little adverse effect on food security.

The evolving concepts of land administration in China: Cultivated land protection perspective

This paper presents a holistic method by integrating three concepts (land resources management, assets supervision and political governance for sustainability) for investigation of land administration in China, taking into consideration of cultivated land protection for a testimony with econometric method. Theoretically, in this self-organizing integrated method, land resources management focuses on the productivity of land; land assets supervision centralizes on the realization of land usufruct rights in land transference; land political governance for sustainability concentrates on harmonious linkage of economic efficiency, social stability and environmental safety of land use. Their interrelations are complex. Methodologically, the results indicate that the theoretical model is feasible to explain variations of cultivated land protection with these three concepts. Cultivated land decreases with increasing land value increment multiples, and is positive with political governance concept, but not in a linear fashion. Finally the results suggest that roles of government in land administration need to be changed and strengthened, supporting complete compensation for land expropriation and modification to policies of cultivated land.     

Co-ordination of land exploitation,exploitable farmland reserves and national planning in China

Land exploitation, as an important strategy to mitigate farmland loss and stabilize grain production, has been adopted to compensate farmland loss due to rapid urbanization in China. Bounded by the limited capacity and obvious spatial variations of national farmland reserves, it is essential to arrange land exploitation activities timely and reasonably. In this study, we propose an indicator for the status of regional land exploitation, the Exploitation Degree, to facilitate an overview of land exploitation programs in China at both provincial and prefectural levels based on project data from 2006 to 2012. To further our understanding of the regional features of land exploitation activities, we employ the Lasso model to identify and quantitatively assess influencing factors on land exploitation. Our study shows that: (1) contemporary land exploitation practices in China are significantly inconsistent across exploitable farmland reserves. Some areas are greatly over-exploited and such irrational land exploitation has been persistent; (2) related national land plans designed to guide land exploitation efforts centered on resource-rich regions and critical areas do not function as intended. Therefore, we suggest that China⿿s land exploitation policy shall be improved by reconsidering the orientation of land exploitation policy, coordinating land exploitation activities with productivity improvements and eco-system protection, and enhancing the power and scope of the plans in controlling and guiding land resource management.     

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.     

Agricultural land protection in China: a case study of local governance in Zhejiang Province

China's rapid economic development following the 1978 reforms has resulted in significant economic, social and environmental change. One consequence of this change has been the accentuation of an existing trend of agricultural land loss and degradation. Although the 1978 reforms and their impacts have been subjected to considerable scrutiny, relatively little research has been directed towards the relationship between the evolution of local government structures and practices and the implementation of agricultural land protection policies. This paper presents an analysis of this relationship in Huzhou Municipality, Zhejiang Province. Zhejiang Province is situated on the eastern seaboard and exhibited the highest average annual per capita growth in China between 1978 and 1995. Huzhou Municipality is a growth centre in the northern part of the province. A synthesis of the factual knowledge and perceptions of 40 key-informants suggests that despite the development of a comprehensive legal framework for agricultural land protection, the interpretation of policy at local levels continues to permit the loss of agricultural land (and attendant environmental costs) to be traded-off against increased economic growth. This suggests a need to re-evaluate the role of local levels of government in China with respect to agricultural land protection issues; to look as much at the ways policies are implemented as at policies themselves. The devolution of administrative responsibility in China and the increasing influence of powerful local economic interests will provide an impetus for such a re-focussing of research at local levels.     

Applying evaluation criteria for the land consolidation effect to three contrasting study areas in the Czech Republic

Land consolidation (LC) is a tool for improving the effectiveness of land cultivation and for supporting rural development. In the Czech Republic it is, in addition, used to remedy the damages and wrongs caused by 40 years of suppression of land ownership. This paper investigates the specific conditions and various outcomes of LC in three study areas, focusing on the evaluation criteria of land ownership and plot arrangement before and after LC. The three study areas contain contrasting observed features, and they therefore provide a good illustration of a whole range of factors that can affect the rate of LC. The author designed LC projects in each of the study areas between 1994 and 2003, and defined two sets of criteria for ex ante and ex post evaluation based on size, shape and juxtaposition of the plots, on the natural and social conditions, and on the economic benefits and advantages of LC for the landowners. The relationship between the ex ante criteria and the three LC indicators was analyzed using a multiple regression approach. The results show that the initial conditions had a strong effect on the outcomes of the LC programmes. Defining the criteria and the models for the Czech Republic will help to improve the methodological principles underlying LC projects, and it will also support the decision-making processes of the LC authorities in order to optimize the allocation of limited funds.     

Characteristics and land use of contaminated brownfield properties in voluntary cleanup agreement programs

This paper reports exploratory empirical research on the property characteristics and land use of contaminated brownfield properties. This research investigated 1415 contaminated brownfield properties in environmental cleanup programs in the states of New York and Texas in the US. This research attempts to clarify some confusion about contaminated brownfield sites, provide detailed information on the diverse land uses that caused the contamination on these properties, and to provide a better base of knowledge about brownfield sites that may be used in developing and implementing policy to remediate and redevelop contaminated brownfields properties in both older industrial regions and in more recently industrialized regions. This research analyzed land use data for these properties at the time they became contaminated and at the time they entered the environmental cleanup program. It also attempts to identify similarities and differences in the characteristics of the properties in these two states with strikingly different histories of industrialization. Several common assumptions about brownfield properties are extracted from the literature review and tested using the data. Some of our results are surprising, including the variety of past land uses of these contaminated brownfield properties and the differences in the history of land use and the characteristics of the properties in the older versus newer industrial region.

Technology,market policies and institutional reform for sustainable land use in southern Mali

To identify appropriate interventions that support sustainable land use; a farm household modelling approach is applied to analyze micro-economic supply reactions to various policy measures. The modelling framework links agro-technical and economic data, and takes both production and consumption decisions into account, allowing land use and production technology adjustments in accordance with farm household objectives. Different types of farm households are distinguished on the basis of their resource endowments, savings coefficients and time discount rate. Actual and alternative (sustainable) cropping and livestock activities for different weather regimes are defined for southern Mali. The effects on sustainable land use and expected farm household welfare of adopting alternative technologies and modifying prices, transaction costs, access to credit and land taxes are demonstrated. Even with full information on sustainable technologies, strong policy interventions are required to halt soil degradation. Structural policies proved to be more effective than price policies to reduce soil degradation while maintaining positive income effects. When prices are determined endogenously, structural policy loses some effectiveness as an incentive for sustainable land use due to the effect of additional supply on local cereal and meat Prices.     

Impact of land tenure on land use in low-income countries

The role of land tenure in agricultural development has been a subject of intensive research, particularly within the context of land and agrarian reform. The complexity of the world's major land tenure systems is well recognized and no attempt is made here to go beyond an overview as this paper limits itself to the impact of land tenure on land use in low income situations. Present land use is determined by a host of factors, of a physical/biological and socioeconomic nature. In applying land evaluation, the question it is necessary to ask is to what extent, when and where land tenure conditions act as a considerable constraining factor impeding a more optimal use of land resources. Even in what used to be low-population density areas (such as Sub-Saharan Africa) it appears that the frontier phase is becoming exhausted and the intensification of agriculture proceeds; it becomes imperative to examine land tenure in relation to land use implications. It is shown that so far a multi-disciplinary approach has often been lacking in treating land tenure and related issues.     

Associating land use/cover information with land parcels represented in LADM

LADM design requires the association of external land use/cover information with cadastral land parcels. In addition to model design, related specifications are to be defined in the implementation. Yet, there are many severe obstacles against defining such specifications that are applicable to all cases. In this context, there are many different types of land use/cover classification systems for different purposes in different data quality, scale and content, which are either designed internationally or nationally. FAO Land Cover Classification System (LCCS), CORINE land cover, INSPIRE land use/cover themes, land use capability classification and Land Parcel Identification System (LPIS) are common international examples.In this study, management of spatial land use/cover data in association with cadastral land parcels represented by LADM was studied in a pilot study area in Turkey. In this context, association of spatial information as sub-divisions of land parcels (sub-parcels) was studied. Different land use/cover data sets (four types) were specifically produced for this study with an LPIS like digitization method. For the association, special overlay operations with and without predefined XY tolerances were carried out. Effects of similar yet different data sets, spatial data consistency between the produced sub-parcel data sets and land parcels, and also errors were analyzed based on the results. It is found (1) that the level of detail (base production scale) of external land use/cover data set increases spatial association errors, (2) that using XY tolerances to reduce these errors causes data inconsistency and (3) that direct spatial harmonization of two data set may be a robust solution when it is possible. In this context, in order to contribute to the implementation of LADM in terms of spatial association of land parcels and external land use/cover data, together with these data processing and analysis work, LADM modelling abstraction, availability and data quality issues of external land use/cover data, updating and maintenance issues were also discussed.     

The interface between land use systems research and policy: Multiple arrangements and leverages

In recent years, interest in the policy-informing role of research organisations has grown considerably. It has been argued from within the science domain that the management of land, whether at the field, farm or regional scale, can benefit from computer-based systems analysis. This proposition was examined through 26 semi-structured interviews, by conducting a workshop on modelling support in policy decision-making and investigating 11 European-based cases of policy-oriented modelling research. On basis of these materials, we assess approaches towards policy-oriented modelling within the domain of agricultural production and other environmental services of land. First, we define the boundary arrangements for our field of interest, i.e. computer-based systems analysis of agricultural production and ecosystems services. Such ideotypical classification of boundary arrangements makes explicit the institutional space in which system scientists function. This space enables certain activities, and at the same time constrains other initiatives, dependent on who is perceived to initiate and/or control research activities and to formulate objectives, and whether it is considered appropriate to integrate scientific knowledge development with policy work. Five ideotypical boundary arrangements are proposed: ‘Civil mandate’; ‘Trickle out’; ‘Janus face’; ‘Critical participant’; and ‘Knowledge broker’. In a second step, a number of critical leverage points are identified based on the 11 cases and these are addressed in relation to the five boundary arrangements. The term ‘leverage point’ covers means, conditions and methods that foster use of modelling work that can be changed, and thus may be part of a strategy to increase the chances that a model is used. The leverage points were: reputation of research institute and/or scientists; raising and balancing expectations; communication about and investment in the scientific basis of the modelling work; participation in model development; heterogeneous and extensive social network in policy domain; institute mandate that secures availability of ‘stepping stones’. We conceive of two applications of our research for modellers who are interested in the use of their work in the policy sphere. First, the boundary arrangement classification helps to interpret the experiences of others and to assess the relevance of lessons and suggestions for their own context. Secondly, the combination of the boundary arrangement perspective and critical leverage points presents a basis to design an institutional pathway for enhancing impact of modelling research in the policy sphere. For those researchers functioning in a science-domain-oriented environment, the analysis in this paper suggests that there are more options than the frequently proposed ‘more participation’ for increasing the likelihood that their policy-oriented work is used. These include establishing contacts with research groups or institutes that are in a position to function as ‘stepping stones’, or engaging with others to develop a social network in the policy sphere.     

Unravelling the dynamics of access to farmland in Tigray,Ethiopia: The ‘emerging land market’ revisited

This article uses ethnographic evidence from Tigray to revisit the debate on informal rural land markets in present-day Ethiopia. It explores informal farmland rental from a historico-anthropological, micro-analytical perspective in relation to the formal allocation of land use rights and to other informal land transfer practices. It shows how different rationales for land rental give rise to different socially embedded tenancy configurations. On the basis of this empirical evidence, the paper questions the appropriateness of the common idea that in Ethiopia ‘the land rental market is expanding’. It argues that research and policy thinking on land in Ethiopia could gain analytical power and relevance by adopting a less monolithic and abstract view on people's informal land transfer practices.
