Biofuels and ecoagriculture: can bioenergy production enhance landscape-scale ecosystem conservation and rural livelihoods?

Global development of the biofuel sector is proceeding rapidly, driven by national policy mandates, government subsidies, and profit opportunities for farmers, agribusiness and energy companies. To date, most investment in—and dialogue on—biofuels has focused on large-scale production of liquid transport fuels. A smaller set of efforts has explored the potential of biofuels to promote rural development by reducing energy poverty among the world's two billion poorest people. Here, we consider the potential of these diverse approaches to promote the goals of ecoagriculture: namely, sustainable agricultural production (including biofuel feedstocks), conservation of biodiversity and ecosystem services and viable rural livelihoods. Using a landscape planning framework, we review empirical evidence and identify criteria for designing biofuel production systems that promote this trio of goals. Biofuel development has the greatest potential when biomass production is an ‘interstitial’ activity and when processing and use occurs at the local level. Larger scale production for regional or global liquid fuel markets may be beneficial under some circumstances, but a stronger policy framework is needed to guide this approach. To advance biofuels for sustainable development, while avoiding serious risks, investment must shift to include a variety of ecoagriculture-compatible pathways. Supportive public policies and market incentives must be developed before the biofuel sector develops strong path-dependence toward unsustainable outcomes.     

区域性中心城市蔓延趋势测度与控制策略 ——以山东省临沂市为例

研究目的:提出区域性中心城市蔓延趋势测度方法和蔓延控制策略。研究方法:维度分析法与实证分析法。研究结果:(1)城市蔓延是多维度现象,要综合运用单一维度测度和综合维度测度两种方法,才能全面认识和测度城市的蔓延程度;(2)临沂市城市蔓延特征总体呈现加重趋势,城市去中心度加重,城市的土地利用混合度逐渐降低,城市通达度逐渐增强,城市开敞空间逐渐减少;(3)城市蔓延是多维度共同作用的结果,要根本改变城市蔓延趋势,需要从不同维度进行综合施策。研究结论:在区域性中心城市成为城市建设用地扩展重点调控的大背景下,有效防控城市蔓延,需要科学编制区域性中心城市发展规划,并依据相关指标的测度结果,系统实施相应的城市蔓延控制策略。

Modelling the urban heat island effect of smart growth policy scenarios in Brisbane

Smart growth policy has been identified as a panacea to tackle a range of undesirable outcomes of sprawl development. Various neighbourhood planning concepts have been developed following smart growth principles such as transit oriented development, and infill development. Existing empirical studies, however, do not answer to a key policy question: can smart growth policies reduce the urban heat island (UHI) effect? If so, what type of smart growth policy would be most effective? This research examined the questions by deriving five alternative neighbourhood planning scenarios for Brisbane for 2023: a) business as usual, b) transit oriented development (TOD), c) infill development, d) motorway corridor oriented development, and e) sprawl development. The research utilises Landsat remote sensing images of 1991, 2004, and 2013 to: first, estimate and validate a Geographically Weighted Regression model in order to identify statistically significant factors influencing the UHI intensities in Brisbane; and second, predict the UHI intensities of the five policy scenarios. Two factors were identified to have significant influence on the UHI intensities in Brisbane: population density, and porosity. Results show that compared to the 2004 and 2013 levels, Brisbane will respectively experience a higher and lower levels of UHI effect in 2023, irrespective of the policy scenarios. On average, the infill development scenario, as a smart growth policy, has a marginally better potential to mitigate the UHI effect in Brisbane in 2023 compared to the sprawl development scenario conditional on the definition applied in this research. The UHI effect would be more equitably balanced spatially under the sprawl development scenario.     

The making of urban financialization? An exploration of brazilian urban partnership operations with building certificates

This paper provides two contributions to the research on urban planning and the financialization of land use. Instead of stressing the consequences of finance on others, it prioritizes the analysis of the social-technical constitution of finance itself within urban planning, and does so in an emerging country setting, which is still relatively understudied in the existing literature. We analyse a specific Brazilian planning instrument, i.e., the sale of securitized building certificates (CEPACs) in large urban (re)development projects (UDPs), as a potential constituent space of urban financialization. The paper explores how planners, financial consultants, contractors and builders/developers effectively shape the contradictory financial and physical design and implementation of UDPs with CEPACs. Although the initial evidence shows that there are still clear limits to the penetration of financial logics into land use planning, continuing regulatory rollout and the increasing activism of foreign investors suggest the instrument’s open-ended trajectory, with a potentially more significant role for financial actors in constituting urban financialization through CEPACs.     

Development of a methodology for the characterization of urban and periurban green spaces in the context of supra-municipal sustainability strategies

Periurban landscapes should be interpreted as multifunctional spaces enabling them to be valued according to environmental, economic and social criteria. This article proposes a methodology for the characterization of urban and periurban green spaces in the context of strategies which enable planning processes for cities of the future to be devised. Firstly, the green belt is characterized and evaluated and its resilience and dynamic analyzed. Subsequently, different supra-municipal tools are compared and a summary of various existing methodologies and programs is produced, making it possible to develop a matrix for diagnosing projects for green spaces and periurban natural spaces and evaluating their potential as a Green Infrastructure in the context of Open Space Strategies. The application of this method in the characterization of periurban space emphasizes elements of scenic beauty whose incorporation in the said strategies does not require large investments but instead an effort in terms of promoting such places. The drafting of this Open Spaces Strategy offers a cross-disciplinary planning tool with which to take action using a landscape reading scale. This comprehensive view makes it possible to optimize efforts and investments and involve the whole community at all levels of operation through processes of citizen participation. As a result, a systematic and collective diagnostic tool is obtained for characterizing the urban and periurban green belt, which can be applied to the various periurban spaces in accordance with the multifunctionality demanded by supra-municipal strategies.
