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.     

Persistence of cattle ranching in the Brazilian Amazon: A spatial analysis of the rationale for beef production

Fed by demand for beef within Brazil and in global markets, the Brazilian herd grew from 147 million head of cattle in 1990 to ≈200 million in 2007. Eighty-three percent of this expansion occurred in the Amazon and this trend is expected to continue as the industry bounces back from a recent agricultural downturn. Intensification of the cattle industry has been suggested as one way to reduce pressure on forest margins and spare land for soybean or sugarcane production, and is the cornerstone of Brazil's plan for mitigation of greenhouse gas emissions. To this end, federal credit programs and research and development activities in Brazil are aligning to support intensification goals, but there is no guarantee that this push for intensification will decrease the demand for land at the forest margin and as result curb CO₂ emissions from deforestation. In this paper we use a spatially explicit rent model which incorporates the local effects of biophysical characteristics, infrastructure, land prices, and distance to markets and slaughterhouses to calculate 30-year Net Present Values (NPVs) of extensive cattle ranching across the Brazilian Amazon. We use the model to ask where extensive ranching is profitable and how land acquisition affects profitability. We estimate that between 17% and 80% of land in the Amazon would have moderate to high NPVs when ranched extensively if it were settled, i.e. if the rancher does not buy the land but acquires it through land grabbing. In addition, we estimate that between 9% and 13% of land in the Amazon is vulnerable to speculation (i.e. areas with positive NPVs only if land is settled and not purchased), which suggests that land speculation is an important driver of extensive ranching profitability, and may continue to be in the future. These results suggest that pro-intensification policies such as credit provision for improved pasture management and investment in more intensive production systems must be accompanied by implementation and enforcement of policies that alter the incentives to clear forest for pasture, discourage land speculation, and increase accountability for land management practices if intensification of the cattle sector is to deter new deforestation and displace production from low-yield, extensive cattle production systems in frontier regions of the Brazilian Amazon.     

Towards sustainable rural development in Central and Eastern Europe: Applying land consolidation

Over the past twenty years, social and economic decline in rural areas has intensified in the Central and Eastern European countries. A precondition for the reversal of this decline is the implementation of new policies in relation to the fundamentals of land ownership and management. In addition to addressing the problems of land ownership fragmentation, these should include measures to improve agricultural production and employment, taxation policy, and legislation to protect land ownership rights, within the context of acknowledging environmental and sustainability considerations. In Europe, the requirement for readjusting unfavourable land fragmentation and promoting the appropriate use of land combining with positive environmental solutions is expected to create new sustainable land management systems. The consolidation of land ownerships may be an effective and active land management instrument which not only addresses the problems of land fragmentation, but also, if applied sensitively, may be an instrument for delivering sustainable rural development in a wider context. The aim of this research is to investigate land consolidation as an essential tool to create sustainable rural areas in Lithuania.     

Toward the sustainable development of urban areas: An overview of global trends in trials and policies

Achieving sustainable urban development (SUD) remains one of the most important goals for many countries. Numerous nations have made attempts to attain sustainable development (SD) by fixing one or more of the problems facing urban development, which has resulted in various approaches to SUD. However, a main issue that could help decision-makers deal effectively with SD needs to be emphasized.This study covers 10 topics that have recently become highly relevant to SUD:(1) A balanced approach to SUD, (2) Socio-cultural awareness, (3) Urban sprawl, (4) Economic urban development, (5) Transportation, (6) Urban renewal, (7) Mitigating greenhouse gases (GHG), (8) Urban vegetation, (9) Assessment systems, and (10) City structure and land use. The methodology is based on an overview of these themes via a critical reading of different publications, mostly from the last five years. This study classifies these topics both quantitatively and qualitatively in order to highlight hot-button issues at the domestic and international levels. The publications that were analyzed showed that Asian countries, especially China, are making changes towards SUD more than nations of other continents. The study concludes that transportation is the most prominent challenge in the field of SUD, followed by socio-cultural awareness. The concern of transportation and socio-cultural conscious issues can propel SUD forward and improve other problems related it.     

A historical political ecology of forest access and use in Sudan: Implications for sustainable rural livelihoods

This paper analyzes and explains the development of forest governance over time and its impact on forest-dependent livelihoods in Sudan. Therefore, a qualitative historical analysis method was used to capture and interpret the analytical dimensions of the Political Ecology Approach (PEA). The historical review of the forestry development provides an insight into Sudan’s transforming governance framework for forest access and use, especially the related legislation, policies and resource administrations. This study concludes that unequally distributed forest resource access and institutional arrangements over time are detrimental factors for forest-dependent poverty and environmental degradation. Our study suggests that a more supportive governance framework, which integrates rural livelihood vulnerability with sustainability parameters, is needed thus to resolve the currently most contradictory forest management paradigms.     

Determinants of crop-livestock integration in Brazil: Evidence from the household and regional levels

Integrated crop-livestock systems (iCL) are advocated as a promising strategy to increase agricultural production and rehabilitate degraded pastures while mitigating GHG emissions. Although iCL in Brazil has increased over the past few years, it still occupies a small share of the country’s total agricultural area. We investigate the determinants of iCL occurrence in Mato Grosso state, a globally important producer of beef cattle and grains that has experienced rapid land cover change and environmental degradation in recent decades. Our analysis encompasses two typical cases of iCL in Mato Grosso (the rotation of soy followed by pasture, and soy followed by maize and pasture) as well as biophysical, socioeconomic, and institutional factors observable at the household and/or municipality levels that may influence the wide-scale occurrence of iCL. Evidence at both scales suggests that knowledge and supply chain infrastructure play an important role in early occurrence of iCL, as they are more common in regions closer to iCL research stations and processing facilities of grains and cattle. On average iCL adopters are more educated and have better access to technical assistance and sector information than specialized farmers or ranchers. Most iCLs are concentrated near established soy areas and greater similarity exists between municipalities with iCL and soy-dominant municipalities vs. pasture-dominant municipalities. Our findings reveal the importance of specific conditions for iCL occurrence and iCL promotion in livestock-dominant regions. Incentives targeted at ranchers are crucial for the achievement of the Brazilian Government’s goal to restore degraded pastures through agricultural intensification.     

Land change in the Brazilian Savanna (Cerrado), 1986–2002: Comparative analysis and implications for land-use policy

The Brazilian Cerrado, a biodiverse savanna ecoregion covering 1.8 million km² south and east of the Amazon rainforest, is in rapid decline because of the expansion of modern agriculture. Previous studies of Cerrado land-use and land-cover (LULC) change imply spatial homogeneity, report widely varying rates of land conversion, use ambiguous LULC categories, and generally do not attempt to validate results. This study addresses this gap in the literature by analyzing moderate-resolution, multi-spectral satellite remote sensing data from 1986 to 2002 in two regions with identical underlying drivers. Unsupervised classification by the ISODATA algorithm indicates that Cerrado was converted to agro-pastoral land covers in 31% (3646 km²) of the study region in western Bahia and 24% (3011 km²) of the eastern Mato Grosso study region, while nearly 40% (4688 km² and 5217 km², respectively) of each study region remained unchanged. Although aggregate land change is similar, large and contiguous fragments persist in western Bahia, while smaller fragments remain in eastern Mato Grosso. These findings are considered in the current context of Cerrado land-use policy, which is dominated by the conservation set-aside and command-control policy models. The spatial characteristics of Cerrado remnants create considerable obstacles to implement the models; an alternative approach, informed by countryside biogeography, may encourage collaboration between state officials and farmer-landowners toward conservation land-use policies.     

Neighborhood socioeconomics,food environment and land use determinants of public health: Isolating the relative importance for essential policy insights

Recent literature has advocated the connection between land use policies with public health promotion. In this regard, examining the land use determinants of public health and isolating the relative importance with other influential factors should provide essential policy insights. However, very limited efforts have been made in this aspect, particularly for the developing countries. Using a case of Wuhan (China), this paper attempts to capture the land use determinants of obesity prevalence among middle-aged adults and to compare the relative importance with neighborhood socioeconomics and food environment. A conceptual framework is first proposed to guide the analysis within a land use policy context. Data are then collected during the China’s National Physical Fitness Survey in 2010 and multivariate linear regression is applied to analyze the district level determinants. Results show that neighborhood socioeconomics, food environment and land use all have significant effects on obesity prevalence among the middle-aged adults. The men obesity is associated with the occupation, education and housing, while women obesity is correlated with income and housing. Women obesity associates with healthy food environment, while men obesity correlates with unhealthy food environment. Open public space is negative to women obesity, and institutional land is negative to men obesity. Greater walkability and street connectivity associate with lower obesity risk for both genders. The variance decomposition demonstrates that food environment is the most important determinant of men obesity, while land use is the most essential determinant of women obesity. For the obesity prevalence among total population, neighborhood socioeconomics are key determinants. Based on our analysis, we finally provide some insights for land use policies that aim at addressing the obesity issue in developing countries.     

Public health in linkage to land use: Theoretical framework,empirical evidence,and critical implications for reconnecting health promotion to land use policy

The increasing health burdens pose great challenge for planners and policy makers to create a more livable city. Recent literature has linked land use to a wide range of illness and death causes in developed nations. It therefore requires evidence-driven and replicable frameworks to inform land use decisions that integrate with health promotion. This paper proposes a theoretical framework for the mechanistic links between neighborhood land use and public health; and then quantifies their associations at district level, using the case of Shenzhen in developing China. Data for 15 health indicators in 2010 are collected at district level; and a set of standardized land use variables (individual land use type, general land use mix, and physical street conditions) are proposed to comprehensively reflect the neighborhood land use characteristics. Spatial regression is employed to analyze the relationships between health outcomes and land use variables. Results show that the land use exploratory variables vary with health indicators, but several key land use determinants are identified: green land abundance, green land morphology, institutional land proximity, industrial land proximity, blue land abundance, street walkability and street connectivity. Structural equation modeling is further applied to examine the possible mediators and it demonstrates that the casual pathways between land use and public health are quite complex. The developed set of standardized land use variables can serve as practical tools to facilitate land use decisions with health considerations. In practice, several complexities at governance levels challenge the efforts to reconnect land use policies and public health promotion. We put forward three useful solutions to enhancing health connection with land use policy across different international settings. This study captures the nuanced health disparities varied with districts and indicators, and therefore produces some more generalized knowledge that ultimately helps develop land use policies aimed at promoting public health at home and abroad.     

Economic benefit and ecological cost of enlarging tea cultivation in subtropical China: Characterizing the trade-off for policy implications

Cash crop expansion has become a global land use issue in recent decades. While the enlarging cash crop cultivation brings promising profitability, it can impair the delivery of various ecosystem services, with a risk of threat to sustainability and human well being. In order to make well-informed land use policy decisions, it requires elaborate efforts to characterize the trade-off between the benefit and cost of cash crop cultivation. This paper focuses on the enlarging tea cultivation in subtropical China, using a case of Anji County. We first monitor tea expansion from 1985 to 2016 based on time-series Landsat imageries, and then analyze the subsequent changes of water conservation service through an in-field survey of soil loss. Monetary approach is finally employed to evaluate the trade-off between economic benefit and ecological cost associated with the growing age of tea plantations. Results show that tea plantations expanded rapidly from 1985 to 2016 in Anji County. Delivery of water conservation service has been significantly impaired by the conversion from natural forests to tea plantations, but it can be gradually improved during the long rotational life cycles of tea plantations. For a given plot (1 ha at moderate slope), in theory, the economic benefit and ecological cost exhibit opposite trend associated the growing age of tea plantations, and an equilibrium point is approximately achieved at the 12-year growing age. In reality, ecological cost exceeds the economic benefit throughout the study period in Anji County. More specifically, the net difference increases from 11575 Yuan in 1985–1469167 Yuan in 2016. It denotes that economic benefit fails to compromise the ecological cost of the enlarging tea cultivation in Anji County. Conflicting land use policies (ecological conservation vs cash cropping promotion) and ‘household contract responsibility’ system should account for the unbalanced relationship between economic benefit and ecological conservation. We finally propose four major options towards the win–win possibilities between economic gain and ecological conservation associated with tea cultivation.     

Land consolidation in inland rural Galicia, N.W. Spain, since 1950: An example of the formulation and use of questions, criteria and indicators for evaluation of rural development policies

This paper examines whether the land consolidation (LC) practised since the 1950s in Galicia, N.W. Spain, has had the desired effects. To achieve this aim, we have adopted the methodology drawn up by the European Union for evaluation of its socioeconomic programmes, and we have adapted it as required by the subject matter and by the long-term historical perspective of this study. Our results suggest that, during the study period, LC has in general made a positive contribution to slowing rural depopulation.     

Toward a systemic monitoring of the European bioeconomy: Gaps,needs and the integration of sustainability indicators and targets for global land use

The contribution of the EU bioeconomy to sustainable development depends on how it is implemented. A high innovation potential is accompanied by considerable risks, in particular regarding the exacerbation of global land use conflicts. This article argues that a systemic monitoring system capable of connecting human-environment interactions and multiple scales of analysis in a dynamic way is needed to ensure that the EU bioeconomy transition meets overarching goals, like the Sustainable Development Goals. The monitoring should be centered around a dashboard of key indicators and targets covering environmental, economic, and social aspects of the bioeconomy. With a focus on the land dimension, this article examines the strengths and weakness of different economic, environmental and integrated models and methods for monitoring and forecasting the development of the EU bioeconomy. The state of research on key indicators and targets, as well as research needs to integrate these aspects into existing modeling approaches, are assessed. The article concludes with key criteria for a systemic bioeconomy monitoring system.     

Land use conversion in metropolitan areas and the permanence of agriculture: Sensitivity Index of Agricultural Land (SIAL), a tool for territorial analysis

In the past few years, urban growth has affected vast agricultural areas, especially in some European regions (EEA, 2006). In peri-urban areas, land consumption is particularly intense, exposing agriculture to the risk of land loss. Assuming the action of different factors, both exogenous and endogenous, on the agricultural system, the potential risk of land use conversion is measured by the Sensitivity Index of Agricultural Land (SIAL), an innovative tool for territorial analysis. In the following paper, the SIAL will be presented with an application for a metropolitan area. In this case study, the exogenous variables of urban proximity seem to be those most involved in the processes of conversion from agricultural to urban land use.     

Water and food in the bioeconomy: challenges and opportunities for development

The world economy is under pressure for greater, more efficient and more sustainable use of natural resources to meet complementary and competing objectives in the food, water and energy sectors. Interactions between these three sectors have become increasingly affected by the bioeconomy—a concept that encompasses economic growth driven by the development of renewable biological resources and biotechnologies to produce sustainable products, employment and income. This article explores how water and the bioeconomy are interlinked, including how the constraints from growing water scarcity—in part caused by development of the bioeconomy—may influence bioeconomic growth. The article describes the impact of biofuel production on water quantity and quality and examines the potential for improved water use through the development of crop biotechnology and improved crop management. Then alternative scenarios for water in the bioeconomy are assessed, and policy conclusions are presented.     

Causal chains,policy trade offs and sustainability: Analysing land (mis)use in seven countries in the South

The need to enhance sustainable development of land use is more urgent than ever; specifically in developing countries where poverty and land degradation are often interlinked. To promote a common understanding of land use problems by experts, stakeholders and decision makers, it is essential to understand the system characteristics, including the complex feedbacks between drivers and impacts. To enhance sustainable development, appropriate policies need to be identified. In this paper, we analysed and compared seven case studies in Kenya, Mali, Tunisia, China, India, Indonesia and Brazil, representing different biophysical and socio-economic conditions and challenges. We analysed Driver Pressure State Impact Response (DPSIR) story lines of the land use problems, policy priorities and value trade-offs as identified by stakeholders and experts in National Policy Forums. Important drivers of land use change impacting main land use problems among the case studies were economic growth, technological development, immigration and agricultural intensification, in addition to existing policies. Of the latter the most important were related to domestic support through various forms of subsidies or access to credit, land tenure polices and liberalization policies. In the policy prioritization, the value trade-offs made by the National Policy Forums emphasize the environment rather than increased economic production. It is recognized that the environment needs to be improved to maintain and improve economic production in the long term, both in agriculture and in other sectors.     

Agricultural land-use dynamics: Assessing the relative importance of socioeconomic and biophysical drivers for more targeted policy

A detailed understanding of multiple human and environmental factors influencing land allocations among agricultural uses can facilitate more efficient and targeted land policy. To show this, we used a comprehensive dataset of socioeconomic, physiographic, and climatic indicators to investigate potential determinants of land-use in Australia’s intensive agricultural region during the period 1992–2010. We applied a seemingly unrelated regressions land-use shares spatial error model with random effects coupled with variance decomposition analysis to identify the statistical significance, direction and magnitude of observed associations between land-use and its drivers.Population: density, rainfall, equity ratio, and access to markets were the most influential policy-relevant land-use factors. Land allocations to cereals and livestock production were significantly influenced by spatiotemporal rainfall and temperature variability. Improved pastures, cereals, annual and perennial crops plantations were larger in regions with better access to markets. Increases in equity ratio (i.e., better financial position) were associated with larger land allocations to improved pastures and annual crops and smaller extensive grazing area. Marginal associations were detected between land-use and output prices, and higher population density was associated with lower shares for all high value agricultural land-uses. The results suggest that improved transportation infrastructure, zoning regulations, and mechanisms to reduce farm debt exposure and risks from climate variability could have significant impact on the configuration of the Australian agricultural landscape.     

Land tenure security: Revisiting and refining the concept for Sub-Saharan Africa's rural poor

In more developed societies the concept of land tenure security is implicit and backed by long standing institutions. In contrast, the concept is less recognised and carries divergent meanings in developing countries. In these contexts past conceptualisation efforts have favoured reductionist approaches: the concept is narrowed to one aspect or another, but, no shared agreement on a definition prevails. The absence of this basic theoretical knowledge impedes discourse on land policy formulation, implementation, and evaluation. This paper contributes to this issue by revisiting and refining the concept of tenure security in the context of Sub-Saharan Africa's rural poor. Using a systematic review, scientific evidence on the conceptualization issue is provided. A typology of different schools of thought is developed: land tenure security is shown to be understood through (1) economic, (2) legal or (3) adaptation lenses. Generic constructs from these viewpoints tend to dominate the notion of tenure security and subsequent land policy formulation; however, it is argued that none adequately describe the totality of the concept. Using the review results and a systems approach a new inclusive concept of tenure security for rural poor in Sub-Saharan Africa is developed. The refined concept of security is defined as an emergent property of a land tenure system. The content of such security is explained by interactions between all elements of a land tenure system as a whole. It is concluded that rural poor in Sub-Saharan Africa can enjoy the total security when interactions between all elements occur in a dynamic equilibrium.     

Spatial development policy: changing roles for local and regional authorities in the Netherlands

Implementation of spatial policy involves intervention in the land market. In the Netherlands local government also acts as a land developer. Due to an increase in activities in the land market by private actors and an increase in the geographical scale of economic and social processes, this practice is under threat. This paper analyses the background and evolution of Dutch spatial development policy during the last ten years, from the perspective of governmental directive function for spatial policy. It focuses on the multi-level governance between local and regional governments and between local government and private actors.
