Although the forager–farmer interaction model successfully explains the gradual transmission of farming technology to foraging groups, it fails to explain rapid, abrupt transition to agricultural economies. This paper suggests that interaction between farmers and foragers often includes conflict and competition over land and that this conflict between different land-use strategies may lead to a rapid, discontinuous transition of subsistence economy. Comparing southern Scandinavian and central-western Korean cases, this paper suggests that the rapid transition to an agricultural economy in central-western Korea was a consequence of the appearance of territoriality of farmers in mobile, land-sharing context, resulting in a decrease in number of resource patches available to foragers.  相似文献

江苏省城镇化发展协调度评价与地区差异分析   总被引:6,自引:0,他引:6  
将城镇化分解成人口城镇化、经济城镇化、土地城镇化和社会城镇化4部分,且认为这4部分应处在协调耦合状态,用TOPSIS法对江苏省城镇化发展协调度进行评价,之后对评价结果的地区差异进行分析,以对城镇发展政策制定提供依据。研究表明:常州和扬州在优质协调区;南京、镇江、苏州和无锡在良好协调区,且土地城镇化相对滞后,说明城镇土地高效集约利用;徐州、淮安和南通在基本协调区,徐州与淮安土地城镇化过快,社会城镇化滞后,表明城镇土地粗放低效利用,同时忽视公共服务产品供给,南通土地城镇化滞后,表明城镇扩张缓慢,城镇化的土地代价水平较低;泰州和盐城在轻度失调区,盐城经济城镇化滞后,泰州土地城镇化滞后,土地集约利用强度大,城镇发展选择的是一种精明增长路径;连云港和宿迁在中度失调区,土地城镇化明显快于其它城镇化,城镇发展土地代价水平高,具有相当过渡性损失。  相似文献

基于乡镇单元人口普查数据以及相应年份的城乡建设用地数据,运用空间分析和统计分析方法,尝试分析城镇-农村尺度江苏省流动人口分布格局的时空演变特征,并揭示驱动人口流动的动力机制。结果表明:①规模分布特征是具有较长大值右尾部的正偏分布,总体的集聚趋势增强,城镇和乡村集聚流动人口差距变大;②空间呈现高值集聚特征,热点区主要集中在长江以南的城镇,沿江地区流动人口高密度区域逐渐连绵化;③增长变化呈现长江以北地区城镇的流入人口增加、农村的输出人口减少,以及长江以南地区城镇的流入人口快速增加、农村的流入人口普遍增加的特征;④经济发展水平差异、乡镇企业繁荣、交通可达和政策导向是影响江苏省流动人口集聚的四大动力。  相似文献

Abstract

Over the past two decades, southern Africa has experienced both exceptionally high AIDS prevalence and recurrent food shortages. International institutions have responded to these challenges by framing them as security concerns that demand urgent intervention. Young people are implicated in both crises and drawn into the securitisation discourse as agents (of risk and protection) and as (potential) victims. However, the concepts of security deployed by global institutions and translated into national policy do not reflect the ways in/security is experienced ‘on the ground’ as a subjective and embodied orientation to the future. This paper brings work on youth temporalities to bear on social and cultural geographies of in/security and securitisation. It reports on research that explored insecurities among young people in Lesotho and Malawi. It concludes that, by focusing on ‘threats’ in isolation, and seeking to protect ‘society’ as an abstract aggregate of people, global securitisation discourses fail either to engage with the complex contextualised ways in which marginalised people experience insecurity or to proffer the political responses that are needed if those felt insecurities are to be addressed. However, while securitisation is problematic, in/security is nonetheless an important element in young people’s orientation to the future.  相似文献

Recent excavations in south‐eastern Wadi ‘Araba in Jordan have revealed the first early Islamic‐period copper‐smelting site known in the eastern side of the valley, which extends south of the Dead Sea to the Gulf of ‘Aqaba. Five test pits were excavated in 2012 at Khirbat al–Mana‘iyya, a prominent copper‐smelting camp in south‐eastern Wadi ‘Araba, Jordan. The results of these excavations demonstrate that the site was primarily active in the seventh–ninth century AD. Its distance from the copper sources of south‐west ‘Araba suggests that its location was chosen based on proximity to wood and water resources, rather than copper ore deposits. The discovery that the site dates to the early Islamic period has implications for previous and future work in south‐east ‘Araba. In particular, it challenges the common—until now—view of the region as virtually devoid of settlement during this period.  相似文献

The argali (Ovis ammon antiqua) assemblages from the Middle Pleistocene site of the Caune de l'Arago (Tautavel, southern France) were studied in terms of zooarchaeology and taphonomy. It is possible to discern palaeobiological information lost during fossilisation, as well as the palaeoethology of the bone collector, by the observation of taphonomic details preserved on the bone assemblages. The observations leave no doubt that both humans and carnivores were involved in the accumulation of argali carcasses in the cave. In some assemblages, the type of bones found in articulation and the gnawing marks observed are characteristic of carnivores. In other levels, the intense fracturing of the major limb bones in relation to their marrow content and mineral density, and butchering marks found on specimens in the earlier levels, are in favour of human accumulation, the modalities of which are discussed. The results suggest that the degree of carnivore activity seems to have been higher in levels M, N and O than in level F. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

This study analyses regional development in provincial China through a case study of Jiangsu following the multi‐scale and multi‐mechanism framework. We have revealed a trend of increasing regional inequality and find it is mainly a result of the rapid development of Sunan (Southern Jiangsu), which also results in rising rural inter‐county inequality. Subei (northern Jiangsu) faces more challenges due to the strong effects of self‐reinforcing agglomeration and the constraints of geographical barriers. The spatial Markov chain analysis reveals that the development status of neighbouring counties has a strong influence on a county's development dynamics; a poor county neighbouring relatively richer counties has a higher possibility to move upwards, and vice versa. The geographically weighted regression analysis reveals that development mechanisms have strong local characteristics and the same mechanism affects regional development differently. Finally, our study confirms that the multi‐scale and multi‐mechanism framework helps the understanding of regional development in Jiangsu.  相似文献
