A long history of increases in population pressure in Java has caused agricultural land use to expand and intensify. More recent land use changes caused the conversion of prime agricultural land into residential and industrial area. Results of a dynamic, regional-scale, land use change model are presented, defining the spatial distribution of these land use changes. The model is based on multi-scale modelling of the relations between land use and socio-economic and biophysical determinants. Historical validation showed that the model can adequately simulate the pattern of land use change. Future patterns of land use change between 1994 and 2010 are simulated assuming further urbanization. The results suggest that most intensive land use changes will occur in Java's lowland areas. 相似文献

This paper examines the importance of national-level institutional arrangements for promoting the EU’s Protected Geographic Indication scheme (PGI). Taking the example of Ireland, for which PGI designations remain comparatively low, it explores whether the approach to providing institutional supports to the PGI scheme is influenced by top-down technocratic governance structures that pertain to food safety and quality certification that encompass the broader operating environment for food production in Ireland. Although the regulation of food safety and quality certification are distinct remits to the administration of the PGI scheme, in the Irish context the same institutional bodies are involved in governance of both. Using a discourse analysis interpretative framework, this paper draws on interviews with Irish producer group members and institutional representatives to examine how governance of the PGI scheme reflects management perspectives and practices more in keeping with a regulatory environment for food safety and quality than with development of place-based food product links. It suggests that incentives to avail of the PGI scheme as a means of realising value-added for producers are not well established because they require the development of more subjective, context-dependent processes and practices linked to geographical place and place identity. These are not easily accommodated under current institutional arrangements that also incorporate food safety and quality remits because these are in turn strongly established through nationally and internationally recognised systems of regulation and benchmarking. The findings point to the benefits to be gained from a more layered governance structure for PGI; devolving operation of the scheme to relevant regional and local development organisations that possess the expertise and relevant local knowledge to (a) incentivise the formation of producer groups, and (b) prioritise mentoring and support for PGI concept development as a clearer reflection of bottom-up rural sustainability policy. 相似文献

LF-Y油田S区在ODP开发调整方案实施中,钻井表明构造边部变陡,含油面积变小,静态方法重新计算地质储量为1 328.30×104 m3,但该储量规模与油田生产动态不相符。结合生产动态法、储量反算法及油藏数值模拟法分析油田储量规模及合理性,指出了S区存在储量计算不足的问题并分析了原因,通过动态信息反算地质储量的方法,反算储量规模在1 450.00×104~1 700.00×104之间,因此该油田西边无井控区域储量潜力可能性较大。结合重新开展的孔隙度反演、精细地质模型、储量计算及油藏数值模拟等研究,再通过静态方法最终计算S区的地质储量为1 566.03×104 m3,储量规模增加了237.73×104 m3。以动态反算储量,并反馈到静态储层评价与储量计算之中,使两者达到较为一致的结果。研究成果不但解决了S区储量不足的矛盾,使模型更加合理,剩余油分布预测也更加可靠,为ODP调整方案成功实施提供了储量基础;而且验证了油藏动态方法对储量问题研究的反证作用,从而实现了油藏动、静态结合解决地质难点问题。 相似文献
