Compliance of land cover changes with municipal land use planning: Evidence from the Lisbon metropolitan region (1990–2007)

In the past few decades, urbanisation has become a major phenomenon in European cities, thus representing one of the key human land cover changes with socio-economic and environmental impacts. In the Lisbon metropolitan region it is estimated that 17% of natural and farmland have been transformed into artificial areas. Since the end of 1990s, specific EU guidelines have been issued to contain urban sprawl and preserve agricultural land. Spatial planning in Portugal obviously is integrating these assumptions into the statutory land-use master plans. But what is the performance of this land use planning system regarding land cover evolution itself? Based on the Lisbon metropolitan region (LMR), one of the major areas of urban growth in Portugal, we examine spatio-temporal land cover patterns between 1990 and 2007 by integrating cross-matrix analysis, spatial metrics, and gradient analysis. Additionally, we overlay these land cover dynamics with municipal master plans that regulate land development in order to assess the compliance levels of this land-use regulatory system. Results indicate that: artificial areas are growing by coalescence and/or by scattered development along an urban–rural gradient; agricultural land is reducing and fragmentation is increasing to enlarge peri-urban spaces; there are high levels of conversion of agricultural land into urban land in protected areas, thus showing a lack of compliance to the land use regulatory system visible in the existing gaps between the original land-use assignments of the master plan and the actual developments.     

Mapping changes in land use/land cover and prediction of future extension of bowé in Benin,West Africa

Desertification and land degradation are worldwide problems affecting soil, vegetation and the livelihoods of rural populations. Bowal (plural bowé) is a particular form of degraded land that occurs in tropical regions and leads to the exposure of ferricretes, which are unsuitable for farming. Bowé are more common on farmland and degraded savanna. Changes in land use/land cover were used to map a region of 6.7 million ha in northern Benin, West Africa in 1975, 1990 and 2010. The changes observed during these periods (1975–1990, 1990–2010 and 1975–2010) were used to predict the occurrence of bowé in the period up to 2050 using Markovian chain analysis. The results showed a considerable change in land use/land cover during the three periods. The types of land on which bowé occur (farmland and degraded savanna) increased in northern Benin by 5.4% per year during the period 1975–1990 and 9.5% per year during the periods 1990–2010, while the natural vegetation (forest, woodland and tree savanna) decreased by the same amount. The future scenarios also predicted the same trend. In the period 1975–1990, 1.28 million ha (26%) of natural vegetation was converted to degraded savanna and farmland while 2.23 million ha (53%) of natural vegetation was converted to degraded savanna and farmland in the period 1990–2010. Based on the dynamics recorded during the period 1975–1990 and 1990–2010 respectively, a total of 1.28 million ha (26% of the natural vegetation that was present in 1975) and 1.29 million ha (31% of the natural vegetation that was present in 1990) will be converted to farmland and degraded savanna in the study area by 2050.Thus bowalization will persist and increase in the period up to 2050. The natural vegetation could disappear if protection and restoration measures are not taken. It is thus important to take measures to stop the degradation and to implement programs to restore soils on bowé based on the soil and water conservation techniques used on highly degraded West African soils, such as zaï pit and stone rows with grass strips. Some native plants species adapted to bowalization and resistant to climate change in northern Benin (e.g. Asparagus africanus, Andropogon pseudapricus and Combretum nigricans) should be used in association with soil and water conservation techniques on bowé.     

Drivers of land change: Human-environment interactions and the Atlantic forest transition in the Paraíba Valley,Brazil

Human societies constantly interact with the environment through mutual feedbacks and adaptations. The aim of this research was to analyze human and environmental dimensions so as to understand how the dynamic processes of land use and land cover change are contributing to the increase of forest cover observed between 1985 and 2011 in the Paraíba Valley, Brazil. The forestry sector, based on eucalyptus plantations, is given particular attention due to its role in these change processes. Multi-layer perception neural network (MPNN) models were adopted to evaluate the influence of independent variables in the process of the forest transition. Based on the model's results, we conclude that the process is conditioned by a set of biophysical and socioeconomic variables that operate during different historical periods and in different landscape settings. The proximity of Atlantic forest remnants was influential in the forest transition for the three periods analyzed: 1985–1995, 1995–2005, and 2005–2011. In the first period of change (1985–1995), topography was most influential. Between the periods of 1995–2005 and 2005–2011, the proximity to eucalyptus plantations was an important factor, indicating a high probability of native forest recovery occurring in the vicinity of these monocultural areas. The forest transition tends to occur in areas less suitable for agriculture at the outset, but as these areas are replaced by forest cover, socioeconomic drivers such as farm credit and economic development play important roles in forest recovery.     

Organizing anarchy: The food security–biodiversity–climate crisis and the genesis of rural land use planning in the developing world

Shortfalls in global food production, coupled with the growing visibility of climate change's disruptive effects, have underlined for many observers the importance of devoting rural lands to their ‘optimal’ use, where they can make maximal contributions to the global imperatives of feeding the human population and maintaining vital environmental services. In this context observers have endorsed rural land use planning as a way to insure that, at least in theory, lands get devoted to their best uses. In practice, land use planning in the developing world has resembled ‘organized anarchy’. Small landholders with insecure land tenure, overseas investors seeking large land deals, NGOs representing indigenous peoples, government officials, and staff from international environmental NGOs and multilateral organizations have come together in strategic action fields to struggle over and sometimes negotiate land use plans for contested landscapes. These plans represent a strategic, spatially explicit response to the climate change–biodiversity–food security crisis.     

Spatiotemporal dynamics of soybean crop in the Matopiba region,Brazil (1990–2015)

Brazil is a world leader in the production and export of grains, particularly soybeans. The newest agricultural frontier in Brazil is the Matopiba region, which is a continuous zone formed by the states of Maranhão, Tocantins, Piauí, and Bahia, located mostly within the Cerrado biome. The objective of this study was to analyze the spatiotemporal dynamics of soybean production and yield in the Matopiba region. We analyzed municipality-based planted areas and production data obtained by the Brazilian Institute of Geography and Statistics during 1990–2015. Yield was estimated from the production and planted area, and the data were analyzed using global and local Moran indices. The results showed that soybean production in the Matopiba region does not occur randomly. Positive and significant autocorrelation was found at the beginning of the time series among those municipalities located in the west of Bahia. This region influenced the soybean expansion from south to north. Currently, high-production areas are concentrated in two autocorrelated blocks: one in western Bahia and the other in the central Matopiba region. Analysis of spatial autocorrelation involving yield showed a decreasing trend at the end of the time series. The presence of municipalities with high yield surrounded by others with low yield, and vice-versa, were observed. The findings of this study could assist local and regional agricultural planning in the Matopiba region, and support related analyses in other fields of agriculture, the environment, and logistics.     

Towards zero deforestation and forest restoration in the Amazon region of Maranhão state,Brazil

The Amazon forest in the state of Maranhão ensures ecosystem services that directly and indirectly affect the life quality of its population and economy, via hydrologic and climatic regulation, among other benefits. Currently, only 25% of the original forest cover (24.7 thousand km²) remains while illegal deforestation persists in a violent process that provokes visible social, economic and environmental harm. Simultaneously, Maranhão has seen record levels of burning, faces a water shortage and fights against the worst social and economic indicators in the country. Conversely, secondary vegetation covers 19.9 thousand km² (27% of deforested area) and is completely unprotected. Contrary to the international commitments assumed by Brazil to combat deforestation and restore forests, some of the political representatives of Maranhão have sought legal mechanisms to further diminish forest cover in public and private areas. To promote the conservation and restoration of Maranhão Amazon Forest, a multi-institutional network of researchers was established in 2015. This viewpoint paper aims to draw attention to this endangered region of the Brazilian Amazon and give science-oriented recommendations to policy makers in order to avoid more setbacks. We argue that Maranhão state must urgently establish a policy of Zero Deforestation, protect secondary forests and comply with the national forest restoration policy, thus ensuring long-term economic sustainability.     

Perception and use of landscape concepts in the procedure of Environmental Impact Assessment: Case study—Switzerland and Romania

The European Landscape Convention (ELC) defines landscape as “an area, as perceived by people, whose character is the result of the action and interaction of natural and/or human factors”. Because all aspects linked to landscape are evaluated during the Environmental Impact Assessments (EIAs) procedure, we assessed the Swiss and Romanian experts’ perception and EIA reports regarding the landscape concept. Therefore, we analysed Swiss and Romanian experts’ perception of landscape, we evaluated concepts and methods used in environmental impact reports to assess landscape characteristics and functions, and how the ELC's aim and objectives are reflected by the EIA reports.The Canonical Correspondence Analysis performed to evaluate the experts’ perception of landscape integration in the EIA procedure showed a significant relationship among pattern of answers and experts’ professional background. Moreover, there is a significant difference between Swiss and Romanian expert's perception. Longer experience in the field and a higher level of education indicates higher awareness of landscape characteristics and properties, which demonstrates that alongside with the initial training, there is a need for developing a coherent long-life learning systems having landscape analysis as a focus.The ELC is familiar to nearly 86% of the Romanian Environmental Impact Assessment actors and nearly 29% of the Swiss experts. By contrast, most of the Romanian EIA reports analysed do not employ many concepts of the ELC, while most of the Swiss environmental reports incorporate objectives of landscape protection consistent with the Convention.Our study relies on the comparative investigation of representative case studies of Environmental Impact Assessment reports for industry, local infrastructures, tourism facilities, and wind farm projects, as well on tracking how the European Landscape Convention is reflected by the EIA reports. We found that EIA reports from both countries evaluate the visual landscape, thus, achieving subjective assessment of landscape aesthetics without focusing on social and ecological sub-systems. Quantitative elements of landscape analysis are mostly absent and it is challenging to evaluate whether environmental assessments are consistent among European Landscape Convention countries.To overcome the abstract way of evaluation of project's impact on landscape through EIA procedure, an improved landscape analysis procedure is needed and we propose developing technical guidelines, under the European Landscape Convention umbrella, in order to enhance landscape management.     

Farmers’ land use decision-making in the context of changing land and conservation policies: A case study of Doi Mae Salong in Chiang Rai Province,Northern Thailand

In Thailand, land use planning and policy decision-making were—and to some extent still are—organized in a hierarchical and disjointed fashion. This is also true for the utilization of public lands, including forest reserves in the northern uplands that are often settled by ethnic minorities. There are, however, instances of change in land policies and regulations and in the way decisions and plans are made. Doi Mae Salong (DMS) in Northern Thailand, where there is a trend towards land use for conservation purposes, is a case in point. This paper aims to explore decision-making by farmers in DMS in the context of changing land regulations and policies from the 1950s to the present. The Institutional Analysis and Development (IAD) framework, together with a historical perspective and with narratives on land management through time, were applied by using in-depth interviews of key informants and group farmers’ discussions as tools. The time period under investigation was divided into three periods of change: The first period, before the year 1960, was an era of security concern. In contrast, the second period, from 1961 to 1996, was an era of emerging conservation priorities. Finally, the third period, from 1997 to the present, is an era of lessons learned from the conservation era. Land use decision outcomes reveal that the decision-making processes of farmers are influenced both by the hierarchical decisions of higher authorities and by horizontal linkages among multiple stakeholders. However, while farmers participate readily in forest conservation activities, they do not play an active role in the process of changing policies.     

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.     

Changing land use in the countryside: Stakeholders’ perception of the ongoing rural planning processes in Flanders

Rural areas in densely populated regions face increasing competition for land. Consequently, land use planning processes must attempt to balance the goals of diverse stakeholders and the process of reaching consensus becomes more complicated. By investigating the perception of the actors involved in rural planning, this research contributes to the knowledge of the strengths and weaknesses of such processes. We have focused on the case of rural planning processes in Flanders in which proponents of nature and agriculture are competing for land. Data are collected through open interviews with key actors such as farmers, representatives of nature preservation organisations, farmers’ unions, and employees of the relevant governmental policy areas. Data analysis according to the grounded theory approach resulted in six categories and 26 concepts that represent the stakeholders’ perception of difficulties in the Flemish rural planning approach. Three points where difficulties arise are (1) the link between envisioning, drawing up the plan and implementation, (2) the need for data, and (3) the role of sectors. We use three concepts from literature (procedural justice, distributive justice and value conflicts) to frame the difficulties observed. Based on this analysis, we discuss several ways to improve rural planning processes.     

Choice experiment,multiple programmes contingent valuation and landscape preferences: How can we support the land use decision making process?

The promotion of cost–benefit analysis for social and environmental policy choices is much debated. Then, the conception of a valuation method for the non-market benefit of these policies is still of a main research interest. Among direct valuation methods, the choice experiment method (CEM) becomes a highly attractive valuation procedure, in giving at the same time the economic value of the impacts of the different components of the policy as well as the global impact of a policy package. However, the main-effect designed protocol aiming to limit the cognitive burden of scenarios’ evaluation disregards the important question of the existence of substitution or complementary relation between these programmes for their main beneficiaries. Furthermore, the independent valuation and summation strategy developed in CEM opens to overvaluation or under valuation of the willingness to pay values. The aim of this article is to conduct testing of the additivity bias with CEM results. The distribution of the willingness to pay values for possible combinations of landscape programmes aiming to maintain two agricultural landscape attributes as well as one moorland attribute inferred from the earlier CEM survey is compared to results obtained with the sequential contingent valuation procedure for multidimensional policy suggested by Hoehn (1991). Our empirical results suggest that the additivity bias is not statistically significant in our case, even if specific relation between landscape attributes due to what we call the composition effect is of concern for the population we interviewed. Furthermore, landscape preferences derived from our empirical investigation support the need for more integration of agricultural issues with the local land-use issues.     

Power,capital, and the poverty of farmers’ land rights in China

This article is intended to conduct a three-dimensional examination of China’s rural land rights and the complex dynamic among political power, economic capital, and farmers’ rights during the past seventy years. First, the study takes a close look at the historical changes in the nature, scope, and ownership of land property in rural China during four significant time periods from 1949 to 2019. Second, it uses Ronald Coase’s theory on property rights in dissecting the four paradoxes and dilemmas in China’s rural land ownership, including the extent of clarity and stability of land property rights, the “three rights system” (the rights to ownership, contracting and operation of land) and three stagnations in defining and exercising such three rights, the simultaneous shortage and waste of land resources, as well as the restrictions on land transactions and the requirement to protect collective property. With examples derived from selected evidence, the article documents how both political power and economic capital have worked together to deprive farmers’ land rights. It concludes with a critical analysis of the current status of China’s rural economy, the problem of applying Western economic theories to China’s reality, as well as the theoretical definition, legal protection and policy parameters of land property rights in China.     

Impacts of climate change,agroecology and socio-economic factors on agricultural land use diversity in Bangladesh (1948–2008)

The paper examines the impacts of climate change, agroecology and socio-economic factors on agricultural land use diversity (ALUD) using a panel data of 17 regions of Bangladesh covering a 61 year period (1948–2008) by applying a dynamic panel GMM estimator. Results revealed that ALUD and total rainfall have actually increased @ 0.19% and 0.02% per year whereas variability in temperature has declined @ 0.06% with significant differences across agroecological zones (AEZs). Among the climatic factors, total rainfall significantly increases ALUD. ALUD is also significantly influenced by agroecological characteristics. ALUD is significantly higher in Ganges River Floodplains but lower in Meghna River Floodplains and Chittagong Coastal Plain. Among the socio-economic factors, ALUD increases significantly with increase in the prices of vegetables, jute and phosphate fertilizer and R&D investment. ALUD significantly decreases with increase in the prices of lentil, onion, sugarcane, nitrogen and potassium fertilizers and extension expenditure. Policy implications include price policies to improve vegetable and jute prices, stabilise/reduce fertilizer prices and investments in R&D to develop crops that are suitable for high rainfall areas as well as specific AEZs in order to promote ALUD in Bangladesh.     

Reconstructing production efficiency,land use and trade for livestock systems in historical perspective. The case of France, 1961–2010

This paper provides an original accounting of changes in livestock production efficiency per livestock category in historical perspective and connects livestock consumption with land requirements and virtual land trade. We use France as a demonstration study and account for productivity changes in terms of energy. Feed rations composition are reconstructed per livestock production and feed crop group over time to account for changes in land use in relation to dietary changes. Land requirements for consumption in France dropped by 28% over the study period besides an increase by 35% of the human population and by 53% of the livestock consumption. The two-fold increase in agricultural productivity is due, for half, to energy conversion efficiency improvements and for half to agricultural yields. Overall, the livestock energy conversion efficiency increased by 45% from 1961 to 2010, poultry gained 84%, pork 17%, sheep&goat 67% and cattle 27%. The feed share of oilcrops and cereals in animal rations doubled against a drop by 35% of feed from pastures. Virtual land imports for oilcrops in relation to livestock consumption in France today amount to 0.9 million ha against a maximum of 1.9 million ha in 1979. Besides its dependence on oilcrops imports, the French livestock sector displays net virtual land exports ranging from about 2.5–5.3 million ha per year over the study period. Gross virtual land trade is today five times higher than the net virtual trade. The difference highlights the share of circular product loops in increasingly integrated agricultural markets at the international scale.     

Water in the city: Green open spaces,land use planning and flood management – An Australian case study

With increasing worldwide recognition of the influence of urban development on the hydrological functions of water, there is growing pressure for urban planning to play a greater role in water resources management. Planning for green open spaces in particular can play an important role, as they support important ecosystem services, including those that assist in flood management. It has been argued that interconnected and strategically planned networks of green open spaces should be planned for early in land use planning and design processes, with consideration of water-related ecosystem values and landscape functions in concert with land development, growth management and physical infrastructure planning. Although there is growing recognition of the importance of green open space planning for water sensitive cities and supportive planning measures, there are few analyses of the actual inclusion of this recognition in plans and strategies, or the presence of related actions and planning mechanisms. This paper addresses this gap by comparatively analysing the approaches taken to regional green open space planning in three Australian capital city-regions. Findings indicate the acknowledgement of relationships between flood regulation and green open space planning and various associated planning mechanisms. However, there is limited explicit integration of flood management and green open spaces planning, and significant on-ground barriers to enabling this integration to occur given the legacy of past planning decisions and the lack of information to support implementation. The paper concludes with recommendations for further research to assist planning for green open spaces as an ally to ecosystem services relating to flood management.     

Land use dynamics driven by rural industrialization and land finance in the peri-urban areas of China: “The examples of Jiangyin and Shunde”

As China experienced rapid economic growth, non-agricultural land, particularly industrial land, expanded significantly within its peri-urban areas. This paper takes two typical peri-urban areas: Jiangyin in the Yangtze River Delta and Shunde in the Pearl River Delta, as cases, and applies landscape ecology indices to analyze land use dynamics through overlay of their land use maps from 2001 to 2010. This research reveals that local cadres such as township governments and village collectives utilize land finance as a strategy to contest the reshuffling of central-local power brought about by the 1994 tax-sharing scheme. Meanwhile, under the stringent land quota system, local cadres allocated most quotas to the industrial sector in order to encourage economic growth. However, the fragmented governance regime, including county/city, township to administrative village and natural village, led to land fragmentation, which had adverse impacts on sustainable development. In general, the research on land use of peri-urban areas requires a comprehensive perspective of social, economic and institutional aspects.     

Sustainability and Land tenure: Who owns the floodplain in the Pantanal,Brazil?

In seeking to achieve poverty alleviation and environmental conservation, public policy has often centred on guaranteeing land titles to local peoples. However, such approaches have brought unintended outcomes, replacing small-scale economies and natural areas by intensive exploitation of resources with no clear improvement in local people’s wellbeing. To understand this, we go beyond a general political ecology framing to consider relations between sustainability and land tenure, focusing on the intersection of economics, ecology and anthropology to understand how land tenure, property and use play out on the ground. We draw together different concepts including bundle of rights, de facto and de jure resource use, property regimes, density-dependence and non-equilibrium theory. The significance of this three-discipline view is illustrated through a case study of the Pantanal wetland, Brazil, where conservationists, the government and the local population contest ownership of the Paraguay River floodplain. Government sought to address conflicts around tenure and access through a narrow view of property, which failed to encompass the overlapping layers of land tenure, property and use on the ground and only served to create further legal battles. This article concludes that a more complex view combining the three perspectives is needed in the case of the Pantanal, and in other cases of contested property rights, in order to resolve conflicting claims and foster sustainability. We dissect both the power plays involved between different groups competing for control of a valuable resource, and the legal frameworks which can and should provide checks and balances in the system. The more nuanced grasp that emerges of local systems of tenure and access, of how these diverge from western property concepts, and of their environmental implications favours a better understanding of local realities, allowing for better management policy and consequently contributing more effectively towards poverty alleviation and environmental protection.     

How feasible is regional integration for reconciling land use conflicts across the urban–rural interface? Evidence from Beijing–Tianjin–Hebei metropolitan region in China

Competition among different uses for land is becoming acute under the process of urbanization, and conflicts related to this competition are becoming more frequent and more complex. This article presents a methodology for confronting this issue. By applying an integrated framework, we explore the implicit role of the Beijing–Tianjin–Hebei Regional Integration (BRI) policy in land use conflicts by focusing on the urban-rural interface, and try to address the research question: “How feasible is BRI for reconciling land use conflicts across the urban-rural interface?” An original structure of the analysis is developed based on the identification of three types of conflicts, namely, conflicts over land use structure, conflicts over land conversion and conflicts over landscape pattern. According to the interactions and relationships among these conflicts, we define broad categories of land use conflict areas. Indeed, these conflicts are all related to the unplanned use of agricultural land reserves, which competes with other more immediate uses, and the over-exploitation of land resources caused by unsustainable urban practices. This policy is clearly a critical objective for optimizing the land use structure. It, however, fails to reconcile the conflicts over land conversion and landscape pattern, especially for considerable agricultural land conversion to non-agricultural uses, and low-density development pattern with mixed residential and industrial land uses. Hence, alternative strategies involving public participation, spatial equity, rural revitalization, land-use system reform, and new type of urbanization, can be identified as viable solutions for land use conflict management, which may be complementary to regional integration. The findings of our paper may also contribute to the policy debate on BRI concerning land use planning and regional sustainability.     

Who owns the land owns the wind? Land and citizenship in the Isthmus of Tehuantepec,Mexico

Wind energy expansion across rural areas interacts with various interests at the local level, generating multiple reactions within communities. The Eólica del Sur wind farm implementation pathway in Mexico is a paragon of different positions vis-à-vis this industry after trying to install 132 wind turbines in other towns since 2006. This paper argues that there is a bias in studies of the politics of wind energy development in favour of oppositional voices, as opposed to groups that endorse wind energy expansion or that have stakes in the sector but neither support nor oppose wind projects per se. Based on fieldwork conducted over three years and semi-structured interviews with Eólica del Sur stakeholders, the paper argues that different responses to wind energy are linked to contrasting ownership claims over land in the region and competing notions of the institutions that should legitimize these claims.
