Planning the horticultural sector: Managing greenhouse sprawl in the Netherlands

Greenhouses are a typical example of peri-urban land-use, a phenomenon that many planning systems find difficult to address as it mixes agricultural identity with urban appearance. Despite its urban appearance, greenhouse development often manages to evade urban containment policies. But a ban on greenhouse development might well result in under-utilisation of the economic value of the sector and its potential for sustainability. Specific knowledge of the urban and rural character of greenhouses is essential for the implementation of planning strategies. This paper analyses Dutch planning policies for greenhouses. It concludes with a discussion of how insights from greenhouse planning can be applied in other contexts involving peri-urban areas.     

What is the most suitable methodological approach to demarcate peri-urban areas? A systematic review of the literature

Unexceptionally all metropolitan areas throughout the world are surrounded by peri-urban areas that are neither urban nor rural in the conventional sense. Peri-urban areas are transition spaces, where the changes in different land uses are incessantly occurring. Determining the boundaries of these areas are critical to develop appropriate policies to manage and preserve them. The perpetual transition in peri-urban landscapes makes the boundary demarcation of these areas highly difficult. This paper aims to answer the question of what the most suitable methodological approach to demarcate peri-urban areas is. In order to address this question, the study undertakes a systematic review of the relevant literature. The findings show that a generic method does not exist to demarcate peri-urban areas as characteristics of peri-urban areas are not uniform across the globe. This paper advocates that techniques for peri-urban demarcation should be geographically specific, and in every case the regional and local contexts–e.g., political system, institutional arrangement, societal characteristic, environmental qualities, and economic drivers that underpin the peri-urban development—should be considered. The study provides insights to policymakers in order to determine peri-urban boundaries by tailoring available peri-urban demarcation techniques to their regional and local contexts.     

Assessing the ability of rural agrarian areas to provide cultural ecosystem services (CES): A multi scale social indicator framework (MSIF)

Assessing the ways in which rural agrarian areas provide Cultural Ecosystem Services (CES) is proving difficult to achieve. This research has developed an innovative methodological approach named as Multi Scale Indicator Framework (MSIF) for capturing the CES embedded into the rural agrarian areas. This framework reconciles a literature review with a transdisciplinary participatory workshop. Both of these sources reveal that societal preferences diverge upon judgemental criteria which in turn relate to different visual concepts that can be drawn from analyzing attributes, elements, features and characteristics of rural areas. We contend that it is now possible to list a group of possible multi scale indicators for stewardship, diversity and aesthetics. These results might also be of use for improving any existing European indicators frameworks by also including CES. This research carries major implications for policy at different levels of governance, as it makes possible to target and monitor policy instruments to the physical rural settings so that cultural dimensions are adequately considered. There is still work to be developed on regional specific values and thresholds for each criteria and its indicator set. In practical terms, by developing the conceptual design within a common framework as described in this paper, a considerable step forward toward the inclusion of the cultural dimension in European wide assessments can be made.

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.     

Multifunctional peri-urban agriculture—A review of societal demands and the provision of goods and services by farming

Peri-urban areas around urban agglomerations in Europe and elsewhere have been subject to agricultural and land use research for the past three decades. The manner in which farming responds to urban pressures, socio-economic changes and development opportunities has been the main focus of examination, with urban demand for rural goods and services representing a driving factor to adapt farming activities in a multifunctional way. Working within the peri-urban framework, this review pays particular attention to the relevance of multifunctional agriculture. Academic discourses and empirical insights related to farm structure and practices beyond conventional agriculture are analysed. Diversification, recreational and environmental farming, landscape management and specialisation, as well as direct marketing are all taken into consideration and discussed within the context of landscape functions. The provision of rural goods and services is contrasted with societal demands on peri-urban agriculture. This review finds that multifunctional agriculture has been commonly recognised in peri-urban areas – a phenomenon that includes a large variety of activities and diversification approaches within the context of environmental, social and economic functions of agriculture. In response to the post-productive, consumption-oriented requirements of the urban society, peri-urban farmers have intensified their uptake of multifunctional activities. Nevertheless, not all multifunctional opportunities are being fully developed when one considers the large and growing urban demand for goods and services provided by agriculture carried out near the city. This paper discusses policy and planning approaches to support multifunctional agriculture in peri-urban areas.     

Flexible land-use and undefined governance: From threats to potentials in peri-urban landscape planning

Densification of cities is presently one of the dominating strategies for urbanization globally. However, how densification of cities is linked to processes in the peri-urban landscapes is rather unknown. The aim of this paper is to highlight the potentials in of peri-urban landscapes to be recognized as complementary providers of urban ecosystem services when green areas in cities are reduced by densification. We suggest that the way forward is to change the perceptions of peri-urban areas from being defined as located between cities and rural areas with a specific population density or a geographical distance, to become recognized as a landscape defined by its functionality. By identifying and describing the functionality in peri-urban landscapes the existing governance gaps can be recognized and thus dealt with through adaptation of existing planning tools. Although not yet articulated, peri-urban areas should be used to facilitate integration of top down and bottom up approaches and thereby closing the governance gaps. We illustrate this reasoning by two examples; one of the establishment of green wedges in Stockholm, Sweden, and the other with the establishments of international Model forests. We conclude that further densification of cities will create a lack of ecosystem services in cities by putting an even higher pressure on the peri-urban landscape and not as suggested today that densification lower pressure on peri-urban landscapes. Rethinking and reframing the peri-urban areas by adapting existing platforms will potentially contribute to a more nuanced discussion on strategies for urban development generally.     

Peri-urban agriculture in Jabodetabek Metropolitan Area and its relationship with the urban socioeconomic system

Peri-urban agriculture (PUA) has been proposed as an important urban element to deal with the challenges of increasing poverty, food insecurity, and environmental degradation as particularly found in rapidly expanding cities of the developing world. However, farming in the peri-urban is under strong pressure from urbanization. The economic and social roles of farming need to be better understood in order to integrate peri-urban agriculture into urban planning. This study used multivariate techniques and Geographically Weighted Regression to analyze statistical data at a village and sub-district, to explore the varying relationships between agricultural activities and urban economic activities, urban poverty and informality, as well as food security. This method was applied in the Jabodetabek Metropolitan Area (JMA) with Indonesia’s capital Jakarta at its core, and it resulted in some important findings. First, PUA was more associated with the increasing low and middle class residential areas and the growing small-middle scale urban economic activities rather than development of tourism and larger traditional market facilities. Second, whereas PUA in the North of JMA was under pressure by the increasing poverty, in the Southeast of JMA it has expanded concurrently with increasing poverty. Third, PUA is strengthened by increasing informal activities in the peri-urban zone that offer alternative jobs and additional income for the farmers. Fourth, PUA in the surroundings of Jakarta as well as in the East and Northeast of JMA has contributed to increasing food affordability as well as strengthening food security policy. Based on these results, recommendations to maintain the PUA have been formulated to support its role for the peri-urban economy, reduce poverty, manage informality, and increase food security.     

Planning for peri urbanism: Navigating the complex terrain of transport services

Transport studies give an indication that peri-urban communities in developing countries, particularly Africa, are faced with poor urban transport services. While this notion is established, there remains a limited understanding of how residents in peri-urban communities cope with such a transport challenge. In view of this gap, this study explores the strategies employed to circumvent the challenges of poor transport services in peri-urban communities of Ghana. The study findings show that due to transport-related challenges such as poor roads in peri-urban communities, drivers from the city do not want to operate between the peri-urban areas and the city center. Rather, drivers convey residents of peri-urban communities only to the edges of peri-urban areas – a point they consider immotorable – making it difficult for them to connect to their homes. As a stop in the gap, there is an emergence of taxi stations at the edges of the peri-urban communities to connect commuters to their homes. Unfortunately, this emerging solution is characterised by safety issues as vehicles used are rickety and poorly maintained. These findings offer two major contributions to urban planning studies: First, it is the foremost research to provide understandings of an indigenous solution to lack of transport services in peri-urban communities. Secondly, it is an important research demonstrating the contributions of taxi drivers to the growth of peri-urban areas.     

Agriculture and the city: A method for sustainable planning of new forms of agriculture in urban contexts

Contemporary cities are threatened by urban development decreasing the overall environmental quality and fragmenting natural and agricultural landscapes. As a result of this fragmentation the number of Non Urbanized Areas (NUAs) present in urban contexts is dramatically decreasing. These areas include cultivated land, Abandoned Farmlands, Grassland, Woods and Shrubs that are often located at the peri-urban cities’ fringes. Among NUAs, farmlands and other forms of urban and peri-urban agriculture provide all three major categories of ecosystem services, provisioning, regulating and cultural services. Recently, New Forms of Urban Agriculture (NFUA) have gained increasing attention from researchers for their promising multifunctionality. Incorporating NFUA into the urban environment will thus improve the sustainability of cities, taking advantage of the multiple benefits and services they can provide.This paper presents a method for the characterisation of NUAs in terms of their physical, ecological and social features. These areas are analysed with different criteria and related indicators structured according to a GIS-based Multi Criteria Suitability Model. The proposed model checks the suitability of transformation of the NUAs toward NFUA, thereby enhancing their ecological and social function as well as accessibility and overall connectivity. Different scenarios of spatial configurations for NFUA have been explored with a sensitivity analysis on the values of used indicators. The method was tested for the municipality of Catania, south Italy, an urban context characterised by a relevant shortage of public green spaces and services.     

Population-dynamics focussed rapid rural mapping and characterisation of the peri-urban interface of Kampala, Uganda

In developing countries, cities are rapidly expanding and urban and peri-urban agriculture (UPA) has an important role in feeding these growing urban populations; however such agriculture also carries public health risks such as zoonotic disease transmission. It is important to assess the role of UPA in food security and public health risks to make evidence-based decisions on policies. Describing and mapping the peri-urban interface (PUI) are the essential first steps for such an assessment. Kampala, the capital city of Uganda is a rapidly expanding city where the PUI has not previously been mapped or properly described. In this paper we provide a spatial representation of the entire PUI of Kampala economic zone and determine the socio-economic factors related with peri-urbanicity using a population-dynamics focussed rapid rural mapping. This fills a technical gap of rapid rural mapping and offers a simple and rapid methodology for describing the PUI which can be applied in any city in developing countries for wide range of studies.     

Into the urban wild: Collection of wild urban plants for food and medicine in Kampala,Uganda

In sub-Saharan Africa, many people depend on natural resources for their livelihoods. While urbanisation causes landscape changes, little is known of how this process affects the use of wild plant resources by urban populations. This study contributes to addressing this knowledge gap by exploring the prevalence and determinants of urban collectors of wild plants in Kampala, Uganda. During February to August 2015, 93 structured interviews were conducted in inner, outer, and peri-urban areas of the city. The findings in this study show that urban wild plants are used by almost half (47%) of the respondents, mainly for medicinal purposes but also as a complement to diets. The findings further indicate that residents with lower income, of younger age (<51 years old), and predominantly living in peri-urban areas are more likely to be urban collectors. Seasonality appears to be of greater importance in collection of food plants than of medicinal plants. Overall, these findings indicate that wild plants occupy an important role in the livelihoods and traditions of Kampala’s residents, and we argue that this should be taken into account in urban planning projects.     

A fine-scale spatial analytics of the assessment and mapping of buildings and population at different risk levels of urban flood

Nowadays, urban flooding is becoming a severe issue in most of the developing and developed countries. The growth of the urbanization rate is also increasing, and the United Nations (UN) projected that 68 % of the world’s population would live in urban areas by 2050. People tend to migrate from rural to urban areas, which expose them more vulnerable to urban floods. The flood-related damages and deaths are increasing every year globally. Using the Birmingham city, Alabama (AL), USA as the study area, the objective of this research is to assess potential damage risks due to flood exposure of buildings and population in an urban area. Different social and environmental factors influence urban floods in an urban area. This paper considered elevation, slope, flow accumulation, land-use, soil types, and distance from the river as significant influential factors to urban flooding. The flood risk model hence can be developed by using an integrated GIS and cartrographic approach, in which we assessed and assigned weights to these factors and formed a GIS risk assessment model, which shows the level of flood risks in the floodplain areas of Birmingham and quantifies and maps both commercial buildings, home buildings, and populations’ exposed to flooding risks. This study found that the Valley Creek area is the highest flood risk zone in Birmingham, and about 48.85 percent of Valley Creek’s floodplain area will face very high flood risk. The findings further reveal that total number of 5602 people are living in high and very high flood risk zones in Birmingham that approximates 44.04 % of the total population in this floodplain area. The physical vulnerability is also assessed, and findings suggest that the Valley Creek zone has the highest percentage of residential (i.e., 56.14 %) and commercial (i.e., 75.34 %) buildings located in very high flood risk areas. Our study providing a GIS risk assessment approach to locating and mapping the areas, buildings, and populations from the most to the least at risks with a fine spatical scale for urban flood risk management. The numbers of vulnerable buildings and populations within each risk category are quantified and their distributions are mapped. Therefore, revealing population’s and buildings’ risks and their geographic information, this flood risk assessment can help local governments and communities prepare better to take actions against future urban flood events in Birmingham, and this integrated GIS and cartographic analysis for fine flooding assessments can be applied to other urban areas for flood mitigation and risk management.     

Horse riding posing challenges to the Swedish Right of Public Access

Increasing numbers of horses are being kept for sports and leisure purposes in peri-urban areas throughout the Western world. This expansion of the equestrian sector represents a multifunctional transition, with new production of rural goods and services and increasing influence on land use.In Sweden, the number of horses has increased from 70,000 to approximately 300,000 over the last 30 years. This increase is putting pressure on the traditional Right of Public Access, an old custom allowing the public to walk, cycle or ride on private or state-owned property.This paper analyses multifunctional land use in peri-urban areas in order to provide a deeper understanding of the potential conflicts arising due to the expanding equine sector and to assess how these can affect the Swedish right of public access and spatial planning.A survey of horse riders and landowners in three peri-urban regions of Sweden revealed that these groups differ in their attitudes towards the Right of Public Access. The data also showed that the expanding equine sector is generating new demands on rural areas and there are questions regarding how the current system of open accessibility can meet the increasing market for equestrian leisure activities. The main conclusion is that there seems to be a strong need for intervention and deliberate creation of new ways of handling the accessibility question, where both a bottom-up and top-down approach may be useful.     

Characterization of urban and peri-urban agroecosystems in three West African cities

Systems of urban and peri-urban agriculture (UPA) take many forms in terms of integration of different activities, production intensities and production orientations. The present study is aimed at a refined characterization of the diversity in terms of production orientation, resource endowments and production strategies of the different types of farm households involved in urban and peri-urban agriculture in three West African cities. A total of 318 UPA households were surveyed using a standardized semi-structured questionnaire in the West African cities Kano (Nigeria), Bobo Dioulasso (Burkina Faso) and Sikasso (Mali). Through categorical principal component analysis and two-step cluster analysis, six distinct household clusters were identified based on resource endowments and the degree of integration of vegetable, field crop and animal production. Three clusters appeared in all three cities; the remaining three were specific for one of the cities each and comprised (i) commercial gardening plus field crop–livestock (cGCL) keeping, (ii) commercial livestock plus subsistence field cropping (cLsC), (iii) commercial gardening plus semi-commercial field cropping (cGscC), (iv) commercial gardening plus semi-commercial livestock (cGscL) keeping, (v) commercial field cropping (cC) and (vi) commercial gardening (cG). Production constraints were similar across the cities, that is, high costs of inputs, water shortages and lack of fertilizers in the garden and field crop production systems, while feeding constraints and animal diseases were the main constraints in livestock production. UPA remains an important economic activity to livelihood strategy for urban and peri-urban farmers. Appropriate policies should be formulated that efficiently target the site-specific constraints for improving the quality and sustainability of UPA production systems.     

Joint problem framing in sustainable land use research: Experience with Constellation Analysis as a method for inter- and transdisciplinary knowledge integration

Land use is an important field of interest regarding sustainability transformations. Research projects which deal with the multiple dimensions of sustainable land use usually apply an inter- and transdisciplinary design and are confronted with challenges of integrating heterogeneous knowledge.In this paper we refer to experience we had during the ELaN project, which followed a systemic approach by linking research on water and land management. Due to this relatively uncommon approach it was necessary to bring together scientists and practical actors as well as distributed knowledge from different areas of expertise. Considering the heterogeneity of the actors it was of great importance to establish a shared understanding of the research problem the project was to deal with during the initial phase. For this step the method of Constellation Analysis (CA) was applied: a visualisation and analysis tool which aims at joint problem framing by focusing on the dominant elements of a social-ecological problem and their relations in a discursive process. Due to the size of the project team and the necessity to involve a broad range of actors, a group of scientists led the iterative process and prepared CA drafts which were validated by practitioners. This design can be categorised as ‘consulting’ rather than ‘participatory’ transdisciplinarity. Proceeding this way can be seen as a compromise between more intense forms of transdisciplinary exchange and forms that are manageable when considering time and resource constraints in third-party funded projects.CA has proven to be a suitable tool for organising processes of mutual understanding between heterogeneous actors and fostering social integration in inter- and transdisciplinary research groups. In ELaN the main benefit of the process was an adjustment and enrichment of problem framing which was formulated in the project proposal thus contributing to integrated system knowledge as a basis for the interdisciplinary project consortium and involved practitioners. The insights gained during this process led to changes in the design of some of the sub-projects as well as the targeted end products. This experience confirms the importance of a structured process of joint problem framing in inter- and transdisciplinary projects, especially for thematic fields of such high complexity as land use research.     

Integrating farmland in urban green infrastructure planning. An evidence synthesis for informed policymaking

The Green Infrastructure (GI) Strategy was adopted by the European Commission in 2013, to promote the deployment of GI by integrating it into main policy areas. Despite a high level of awareness for a policy integration across sectors at the EU level, urban and peri-urban farmland (UPUF) is up to now barely considered. A systematic evidence base addressing the contributions of UPUF can support a more informed policymaking. To address this, our paper developed a first evidence synthesis, to evaluate potential of UPUF contributing to policy objectives, thereby tackling major urban challenges. Furthermore an analysis of policy documents revealed gaps on the current state of policymaking and potentials for the integration in future policies. Due to a reciprocal consideration between EU level policies and scientific knowledge this work provides information that help to further construct scientific evidence to address policy concerns while taking into account multiple perspectives. Furthermore, we discussed the implications of our findings for further UGI research and policymaking and thus hope to extend the current political debate across policy sectors.     

Stakeholder engagement in water policy: Lessons from peri-urban irrigation

In highly urbanised Australia many cities and towns demand may have exceeded existing water supply. In peri-urban areas this can lead to conflict over access to supplies with priority often given to urban users. In an effort to resolve potential conflicts, water management planning often seeks to engage ‘community stakeholders’ in an attempt to produce a ‘harmonised’ strategic plan. In this paper we focus on the process of developing one such plan for sustainable water management in a peri-urban area with complex and conflicting stakeholder interests. We subject data from a series of planning meetings and ‘stakeholder’ workshops to a critical review and analysis against the project's stated aims for this stage of the process of: engaging key stakeholders, developing a common vision, and deciding research priorities. We conclude that the approach was unable to achieve these strategic outcomes. In discussion we explore how this analysis reflects barriers in the engagement process, which highlight more general concerns about this widely accepted model for stakeholder engagement in resource issues.     

The “sowing of concrete”: Peri-urban smallholder perceptions of rural–urban land change in the Central Peruvian Andes

Policy makers concerned with the peri-urban interface find their greatest challenges in the rapid urban growth of developing mountain regions, since limitations caused by relief and altitude often lead to an increased competition between rural and urban land use at the valley floors. In this context, little attention has been paid to the affected agriculturalists’ perceptions of peri-urban growth—important information required for the realization of sustainable land use planning. How is the process of rural–urban land change perceived and assessed by peri-urban smallholder communities? Which are the major difficulties to be overcome? By what means are the affected people reacting and how are these adaptation strategies linked with the ongoing landscape transformations of the hinterland?By using the example of Huancayo Metropolitano, an emerging Peruvian mountain city, it is shown that rural–urban land change is intensively discussed within peri-urban smallholder groups. Although urbanization also leads to infrastructure investments by public institutions—an advantage perceived throughout the study area—the negative impacts of rural–urban land use change prevail. The perceptions’ analysis reveals that the decrease of fertile and irrigated agricultural land at the quechua valley floor is especially considered to threaten subsistence, food and income security. In order to compensate the loss of production capacities, many smallholders try to expand or intensify their land use at the suni altitudinal belt: an agro-ecological zone characterized by steep and nonirrigated slopes that can actually not be used for the year-round production of crops previously cultivated at the quechua zone.     

Assessing spatial dynamics of urban growth using an integrated land use model. Application in Santiago Metropolitan Area, 2010–2045

Scenario analysis of urban dynamics from spatial land use models can support urban, planning and policy. An integrated modeling approach, linking assessment of urban spatial dynamics, was applied to the Santiago Metropolitan Area (SMA). The integrated land use change model combines, a logistic regression model, Markov chain, and cellular automata. This model was calibrated with data, from 1975 to 2010, and was used to make predictions for the years 2030 and 2045, using two datasets of, urban and non-urban explanatory variables. Urban change estimates showed the highest fit during the, model calibration phase. The true-positive proportion and standard Kappa value (κ) were of 99% and, 0.87 respectively when validating against an urban cover reference map from 2010. Urban growth was, equal to +27,000 ha (72%) for the period 1975–2010, and the city of Santiago is projected to, reach approximately 93,000 ha by 2045 (+43% from 2010). In the SMA the most important, urban growth pattern is peri-urban development, referring to widespread boundaries and higher, fragmentation in peripheral municipalities. Predictions for 2030 estimate that ∼15% of the projected, urban expansion will occur outside the boundary set by the current Regulatory Plan proposal. These, results demonstrate the capacity of the integrated model to establish comparisons with urban plans, and its utility to explain both the amount and constraints of urban growth. The integrated approach of, urban dynamic assessment using land use modeling is useful for spatiotemporal representation of, distinct urban development forms.
