Land Use in Western Australia: the Need for Change

The need for changes in land use has become more evident from analysis of continued declining trends in land and water resource quality. Land use change in this sense refers to changing existing resource management techniques towards ecologically sustainable development. For example, planting cleared areas towards natural water balance, creating better microclimates and improving soil stability. This paper examines existing land and water legislation and the role and scope of government and the community in achieving changes to traditional resource management including reference to economic and biophysical aspects.     

Linking Agricultural Policies with Decision-Making: A Spatial Approach

Abstract

The loss of agricultural land and its implications have been of great concern in the last decade. By undertaking a spatial analysis of the appropriation of agricultural land for urban use with an overlay of population and urban data, a focus on the consequences of certain regulations on the dynamics of land-use change is explored. This is achieved by integration of data inventories of agricultural land use for Portugal, and linking this information with CORINE Land Cover data as to assess change in the Algarve. An integrated assessment of agricultural land loss follows, undermined by the consequences of urban sprawl. In this sense, this paper expands on the currently existing decrees which provide support to sustainable development in the region while providing a qualitative assessment of future roles based on ethical values and economic efficiency and offering a feasible framework for policy-makers regarding the trends of urban/agricultural dichotomy in a planning and decision-making context.

Spatiotemporal Changes in Landscape Pattern in Response to Afforestation in Northeastern Turkey: A Case Study of Torul

Abstract

Monitoring and understanding of land use/forest cover dynamics as well as the factors affecting the changes in land use/forest cover are necessary for the sustainable management of natural resources. This study analyzes the spatial and temporal changes in land use and forest cover patterns in a typical mountain forest area in the Torul State Forest Enterprise area of Northeastern Turkey. The investigation evaluates the temporal changes of the spatial structure of forest conditions through the spatial analysis of forest-cover type maps from 1984 and 2005 using GIS and FRAGSTATS. The evidence presented here showed that there were drastic changes in the temporal and spatial dynamics of land use/forest cover, and between 1984 and 2005 there was a net increase of 19.9% in total forested area. Productive forest area increased by 3161 ha, although degraded forest area increased 9216 ha. In examining the changes of crown closure and development stages of the forest ecosystem during the study period, the forest stand area with low crown closures increased. The regenerated area increased because of regeneration activities while the other development stages were left to grow to older development stages in the period. These results regarding the crown closure and development stage show that forest quality has increased, and this is partly due to emigration of the rural population in Torul. In terms of spatial configuration, the landscape structure in Torul, the State Forest Enterprise area, changed substantially over the 21-year study period, resulting in fragmentation of the landscape as indicated by large patch numbers and smaller mean patch sizes, owing to heavy timber subtraction, illegal cutting, and uncontrolled stand treatments.

Evaluating Ethnopedological Knowledge Systems for Classifying Soil Quality. A Case Study in Bo Hamlet with Muong People of Northern Vietnam

Ethnopedological knowledge is incorporated in a case study for sustainable land management of mountain karst areas in Vietnam. The research is based on a multidisciplinary approach, including participation of local inhabitants for identifying and classifying local indicators of soil quality, next to scientifically sound approaches to soil quality assessment based on analytical soil data and a statistical treatment of the results. The case study focuses on Bo hamlet, located in the Ngo Luong commune of the Tan Lac district, Hoa Binh province. The participatory approach reveals that local people of the Muong ethnic group distinguish seven land use types and six soil types. They also identified nine local indicators of soil quality: presence of earthworms; crop productivity; topsoil colour; presence of a humus layer; soil surface compaction; erosion; slope gradient; surface water, and soil moisture status. Based on this indigenous knowledge, 19 soil samples from nine soil profiles in Bo hamlet were analysed for fertility indicators. Laboratory results confirmed the validity of indigenous knowledge for identifying and classifying local indicators of soil fertility, compared to scientific standards of soil quality.     

中国古代文明可持续发展的原因分析

中国古代文明持续发展,在世界文明史上是极为少见的。究其原因为,一方面是地理环境的基础作用,独特地理位置、封闭而又复杂的地理环境使其然;另一方面,中国古代大一统的历史和文化起着决定性的作用。相对封闭、完整且一脉相承的文化是其内在动因;人口、土地开发和技术水平三者关系的协调是其前提;先进的农耕制对土地资源的保护是其基础;文明中心随环境而变迁,保证了古代文明的持续发展。

Research in the spatial sciences: how are Canadian geographers contributing?

Geographic data collection, manipulation, analysis and visualization options have experienced substantial improvements during the past several decades, largely spurred by advancements in computing capabilities. While geographers are often credited with identifying and expanding many of the emerging application areas and innovations for the analysis of spatially (and sometimes temporally) referenced data, we are specifically interested in the role of Canadian geographers in the rapidly evolving domain of spatial science. We pose the following provocative question with the intent of not only summarizing the Canadian literature, but also to stimulate an informed discussion: ‘are Canadian geographers developers or users of spatial analytical methods?’ We review the refereed literature from 1980 to 2008 to describe the nature of contributions by Canadian geographers, beginning at about the time of widely accessible computing (1980s). Our summary broadly classifies subdisciplinary contribution areas as being best described as GIS, remote sensing, or spatial statistics, while each contribution area may take the type of algorithm development, advancement and synthesis of theory, or the application of existing methods. We paint a picture of the current contribution landscape and reflect on significant achievements while commenting on some potential weakness that with increased resources and focus might become future realms of advancement.     

Representing Crisis: The Theory of Himalayan Environmental Degradation and the Project of Development in Post-Rana Nepal

Erik Eckholm is attributed with having popularized a theory of environmental crisis in the Nepal Himalaya. In his treatise Losing Ground (1976), he links population growth to contemporary upland deforestation and soil erosion, which are presumed to cause downstream flooding and silting. Since the 1980s, this theory has come under intense criticism on empirical, theoretical and ideological grounds, although it remains a sacred cow in the popular press. A historiography of the theory reveals that representations of and discourses on the nature and extent of environmental degradation have been an important dimension of three distinct aid regimes that shaped the post-World War II development project in Nepal. As such, within specific historical and institutional constellations, some conclusions have seemed more tenable than others, and certain interventions have become more legitimate. Moreover, the production of environmental interventions is intimately connected to the production of environmental knowledge, both of which are intrinsically bound up with power relations. Therefore, the facts about environmental deterioration have become subordinate to the broader debates on the politics of resource use and sustainable development.

LOCAL PUBLIC SERVICE PROVISION AND SPATIAL INEQUALITY IN CHINESE CITIES: THE ROLE OF RESIDENTIAL INCOME SORTING AND LAND‐USE CONDITIONS

Spatial inequality refers to unequal access to local public services between high‐ and low‐income households in relation to their residential locations. We examine two hypotheses regarding the role of income sorting and land‐use conditions in shaping spatial inequality in Chinese cities, where residents have little direct influence on local public service provision. First, in the presence of resource indivisibility, travel cost, and location‐based rationing, scarcity of public‐service resources in a city makes access to public services more uneven across neighborhoods, thus exacerbating income sorting and spatial inequality in the city. Second, the exacerbating effect of resource scarcity is mitigated by land‐use conditions that limit income sorting. Estimates of willingness to pay by households of different income levels for public‐service resources across cities corroborate both the exacerbating effect of resource scarcity and the mitigating effect of inclusive land‐use conditions.

SPARK: Strategic Planning Approach for Resilience Keeping

In a world in growing turbulence, complexity and uncertainty, where crisis is becoming the norm rather than the exception, resilience is increasingly seen as a critical feature that reflects the capacity of a system to absorb disturbance and reorganize without collapsing. Resilient systems are more adaptable to change, are more able to learn and are less vulnerable to disturbance and external shocks (e.g. natural phenomena, economic crises or political shifts). The resilience theories are re-emerging as a field of research and practice with application to socio-ecological systems, fostering new insights in the discussions about sustainable development. The main purpose of this paper is to explore resilience as a concept and as a framework for promoting more sustainable trajectories, highlighting its potentialities and advantages for policy and planning processes. SPARK, or the strategic planning approach for resilience keeping is introduced in the paper as a new sustainability framework, following key underlying concepts and seven key principles that capture the essence of resilience theories. The paper advances a methodological concept proposal for resilience assessment and planning that aims to contribute to linking theory and practice, performing knowledge brokerage and enhancing policy learning.

Property,Authority and Citizenship: Land Claims,Politics and the Dynamics of Social Division in West Africa

In the contemporary African context of rising competition and anxiety over access to land, neoliberal policy interventions designed to clarify property rights, broaden political participation and increase official accountability have frequently provoked rather than alleviated social and political conflict. Comparing case histories of local struggles over land and authority in selected rural areas in Ghana, Côte d'Ivoire and Bénin, this paper argues that in situations where access to land has been linked historically to claims on authority and social belonging, pressures to privatize or clarify ownership have intensified debates over citizenship and governance as well as over land claims per se. Ensuing struggles over land and entitlement have intersected with national as well as local economic and political dynamics, reinforcing ‘traditional’ hierarchies, contributing to the proliferation of formal and informal governing agents and institutions, and frequently disrupting or subverting open governance and sustainable resource use, rather than helping to create conditions for sustainable development and democratization.     

耦合管控效应的城市空间多情景模拟与政策分析

将城市扩展数量管控、土地差别化管控及土地利用分区管控等多个政策方案,嵌入元胞自动机的转换规则中,进行耦合管控效应的城市空间多情景模拟与政策分析。研究结果表明：①在城市扩展过程中,伴随着生态用地面积锐减、建设用地利用效率低下及土地利用结构不合理等风险,政策管控有利于缓解上述问题;②土地政策不能扭转景观破碎化及复杂化加剧的现象,但可以抑制其趋势;③多政策同时使用可以在保护优势斑块方面产生协同效应,其效果优于单独使用三种政策,但在遏制景观破碎化和复杂化方面不能发挥单一政策所具有的最大生态效应;④土地政策的优先级为：数量管控-> 分区管控-> 差别化管控。
