Management Challenges for Aboriginal Cultural Heritage in Peri-urban Queensland

It is often assumed that places of cultural significance to Aboriginal and Torres Strait Islander peoples are protected under cultural heritage legislation such as the Aboriginal Cultural Heritage Act 2003 in Queensland. Such Acts are improvements on previous policies, which all but neglected Aboriginal cultural heritage. Nevertheless, the aims of policies developed at wider geographic scales, such as States within the Australian system, continue to be disconnected from the experiences of some local Traditional Owners. In this paper, we examine conflicts between non-local policy and on-ground management decisions for Aboriginal cultural heritage in peri-urban Queensland. We focus on the challenges of local Traditional Owners in peri-urban landscapes, basing our discussion on recent experiences conducting research on Indigenous land management in southeast Queensland. We examine three case studies: one in which colonial heritage values were prioritised over existing Aboriginal cultural heritage values, a second where local government failed to support a private landholder’s attempt to identify and protect a cultural heritage site, and a third where a cultural heritage site was protected but in a way that restricts the continuation of cultural practices. Developing more productive and equitable relationships between Traditional Owners and non-Indigenous decision makers, with regards to Aboriginal cultural heritage, requires new locally developed processes for engagement and we suggest how this could be achieved.     

Oil and gas development exposure and conservation scenarios for Greater sage-grouse: Combining spatially explicit modeling with GIS visualization provides critical information for management decisions

During the last quarter-century, global demand for energy has increased by more than 60%, and a similar increase is anticipated to occur by 2030 (Raymond, Deming, & Nichols, 2007). In the U.S., oil and gas development is projected to continue across western states within sage-grouse habitat. Greater sage-grouse, recently a candidate species for protection under the Endangered Species Act (ESA), have well documented negative responses to oil and gas disturbance. In this study, we create spatially-explicit oil and gas future development scenarios, baseline and high, and link them to sage-grouse population and habitat maps to quantify future exposure risk within Western Association of Fish and Wildlife Agencies (WAFWA) sage-grouse management zones (MZ) I and II. We then analyze recent land use decisions from the Bureau of Land Management (BLM) along with enacted policy from the State of Wyoming to estimate how these management actions might minimize the exposure risk of sage-grouse to oil and gas development into the future. Our results show that BLM and Wyoming conservation plans could reduce the exposure of sage-grouse to oil and gas development from 15-27% to 11–17% (31–37% reduction) in MZ I and from 15-27% to 5–9% (64–68% reduction) in MZ II. Our estimates of exposure to future oil and gas development, and conservation measures designed to ameliorate those threats, represent the upper and lower extents of potential impacts within scenarios. Our work demonstrates how spatial modeling and GIS visualization can be used by managers to assess likely outcomes of conservation decisions.     

Optimal rural land use allocation in central China: Linking the effect of spatiotemporal patterns and policy interventions

Rural land use development is experiencing a transition stage of socioeconomic and land use development in China. Historic land use transition process and policy interventions have key influence on the applicability of land use allocation solutions in future land use management. Strategic land use allocation is therefore required to possess a good adjustment capability to the transition process. Although heuristic optimization methods have been promising to solve land use allocation problems, most of them ignored the spatially explicit effect of historic land use transition and policies. To help resolve this issue, this study aims to optimize future land use pattern in the context of rural land use development. We took Yunmeng County, one of the typical major grain producing and rapidly urbanizing areas in central China, as a case study and solved the sustainable land use allocation problem by using an improved heuristic optimization model. The model was constructed based on the integration of a spatial discrete particle swarm optimization and cellular automata-Markov simulation approach. The spatiotemporal land use patterns and policy interventions were represented by the CA-Markov as in spatially explicit transition rules, and then incorporated into the discrete PSO for optimal land use solutions. We examined the influence of the joint effect of spatiotemporal land use patterns and policy interventions on the land use allocation outcome. Our results demonstrate the robustness and potential of the proposed model, and, more importantly, indicate the significance of incorporating the spatiotemporal land use patterns and policy interventions into rural land use allocation.     

‘Development’, resistance and the geographies of affect in Oecussi: Timor‐Leste's Special Economic Zone (ZEESM)

In 2013, it was announced that Timor‐Leste's Oecussi enclave would become the site of a special economic zone. Arid, and inhabited mostly by semi‐subsistence farmers from West Timor's Meto ethno‐linguistic group, the plan entails remaking the enclave as an industrial, transport and tourism hub. To facilitate this, in mid‐2015 the authorities began the process of clearing hundreds of indigenous gardens and homes from land slated for mega‐projects intended to make the region attractive to foreign investors. In this paper, I describe how, for many Meto, land tends to be experienced as a spiritually mediated ‘geography of affect’ (Lea & Woodward, 2010) in which questions of place, belonging, spirituality and personal fortune cannot easily be divided, a reality that raises questions about the suitability of the plan's vision of globalized and investment driven ‘development’. Drawing on Scott, I argue that in Oecussi, spirits associated with the land are not apolitical, but are sometimes perceived as acting to protect locals against powerful outsiders – a characteristically Meto ‘weapon of the weak’ that is in keeping with their previous encounters with colonial regimes.     

山东省农村居民点转型的空间特征及其经济梯度分异

为探究农村居民点转型的空间结构及其与经济发展的关联性,以山东省为例,基于农村宅基地转型的理论假设与测度方法,运用空间关联分析方法研究农村居民点转型的空间布局和集聚特征,并以人均GDP作为特征指标划分各县级行政区的经济发展梯度,从省级全域层面和“点、线、面”特征单元综合的角度,揭示农村居民点转型与经济发展的相关性及其耦合关系。结果显示,在空间分布上,2005-2014年山东省农村居民点转型指数呈现西高东低和南高北低的态势;在全局趋势上,Moran's I指数达到0.6317,说明农村居民点转型存在显著的空间集聚现象;在局部趋势上,农村居民点转型的热点区和次热点区集中分布在鲁西黄泛平原、鲁西南淮河平原以及鲁中沂蒙山区,次冷点区分布在次热点区外围,冷点区分布在胶东丘陵地区和鲁北黄河三角洲地带;在相关性分析上,农村居民点转型与经济发展水平具有明显的数理统计相关性和空间耦合性,无论是全域层面还是特征单元,农村居民点转型均表现出从低级到高级经济梯度的递减规律、且乘幂变化趋势显著。本文探索了农村居民点转型的空间特征,弥补了土地利用转型空间性分析的不足;同时研究结果也较好地验证了前人提出的理论假设。     

上海市地下商业空间使用权估价及空间分异

目前的土地估价不仅很少考虑地下空间价值,而且缺乏相对成熟的地下空间估价体系和方法。首先结合成本法、收益还原法及楼层效用比法,建立地下空间使用权价格评估模型。然后,分析了地下空间使用权价值的主要影响因素,发现区位、交通、商业经营等因素显著影响地下商业空间的效用;指出为了提高估价的准确性,地下商业空间效用应该分级、分类设置,而不能笼统地确定为同一水平,并据此测算出上海市地下空间使用权地价分配率。基于所构建的评估模型,以上海市地下商业空间为例,通过克里金内插法,廓清了上海市地下空间使用权价格的空间分布状况;最后,从典型购物中心、市级商业中心和全市商业用地成交地块三个维度,探讨上海市地下商业空间使用权价格的空间分异特征。结果表明：① 上海市地下空间使用权价格空间分布与地上土地使用权价格分布规律基本一致,并由市中心向郊区递减;② 地下商业空间使用权价格对地下轨道交通具有较强的依赖性;③ 与地上商业空间使用权价格分布相比,地下商业空间使用权价格分布的集聚性特征更明显。     

城乡土地市场一体化对土地利用/覆被变化的影响研究综述

为了破除城、乡土地市场分割现状,最终实现“山水林田湖”共同发展的目标,需要推进城乡土地市场一体化发展。分别从城市土地市场、农村集体性建设用地非正式市场和农村农用地流转市场3个方面对土地利用/覆被变化的影响机理研究进行梳理。结果认为：第一,城乡土地市场割裂的状况仍然存在,并且对土地利用/覆被变化产生较大影响;第二,城市国有建设用地市场的发育程度不同,直接影响土地供求关系和土地利用结构,甚至对土地利用配置效率产生影响;第三,农村集体性建设用地市场已现雏形,但由于产权的模糊性而缺乏法律上的监管和保障,加快了土地利用类型的过度非农化转化。另外,农用地流转市场的出现也改变了土地利用的功能和类型;最后,城乡土地市场分割现象会对土地利用系统的可持续性和生态环境产生一定影响。在以上研究结果基础上认为未来研究需要进一步加强对城乡土地市场一体化的分析,且揭示城乡土地市场一体化对区域土地利用/覆被变化影响机理（格局、过程、效应）。

中国住宅出让地价发育特征及其影响因素分析

基于中国土地市场网2009~2013年招、拍、挂出让的住宅用地数据,以县级行政区域作为研究单元,建立区域住宅地价综合模型,选取地价水平、地价增长率和交易宗数作为评价指标,采用Ward系统聚类法,综合分析了中国住宅出让地价的发育特征,利用多分类Logistic回归模型探索了各类地价发育形态的潜在影响因素。结果表明：① 研究期内中国住宅出让地价总体呈现东高西低、沿海高于内陆、城市群带动周边区域发展、城市群内部围绕中心城市增长等空间格局特征;中西部地价高增长的单元多于东部,西北、东北中南部、四川盆地、河西走廊以及长江中下游地区是地价高增长的聚集区;住宅市场活跃度呈阶梯状变化,活跃度较高的地区主要分布在山东半岛、长三角、长江中游、辽宁中部、哈尔滨、成渝、滇中、呼包鄂等城市群。② 根据综合特征,中国住宅出让地价空间发育可分为成熟稳健型、发展完善型、成长发展型、萌芽起步型和成长受阻型5类,相邻发育形态在空间关系上表现出互为邻里的特征。③ 各类发育区的主要影响因素差异显著。区位条件、居民收入和财政收入是地价发育成熟度的主要影响因素;人均GDP、国土开发度提升将促进地价形态发育程度;而人口吸引力不足、基础设施建设相对滞后等将导致地价形态发育受阻。     

改革开放以来珠江三角洲基层非正规土地利用实践与制度创新——以东莞市长安镇为例

21世纪初,在对非正规经济研究的二元主义、新马克思主义和新自由主义理论解释基础上,出现了批判管治主义理论,重点关注国家权力与制度对非正规性产生的影响。基于该视角,以东莞市长安镇为例,运用质性研究方法,分析了改革开放先行区的珠江三角洲,其基层非正规土地利用实践的产生、表现及其与制度创新之间的关系。研究发现：改革开放以来,在国家土地制度缺失、正规土地管理制度颁布和实施阶段,以及省级政府主导的土地制度创新阶段,非正规土地利用实践经历了被政府鼓励、包容和默许及正规化的过程。部分非正规土地利用实践成为制度创新的根源。土地制度的演变经历了由乡村基层“自下而上”式向地方政府“自上而下”式推动的转变,在演变过程中具有非正规性特征,并服务于各个时期的城市与经济发展需求。未来的研究中,应更多的关注“自下而上”的制度创新和地方实践。
