Opportunities and constraints for intensive agriculture in the Hawaiian archipelago prior to European contact

Intensive agricultural systems interact strongly and reciprocally with features of the lands they occupy, and with features of the societies that they support. We modeled the distribution of two forms of pre-European contact intensive agriculture – irrigated pondfields and rain-fed dryland systems – across the Hawaiian archipelago using a GIS approach based on climate, hydrology, topography, substrate age, and soil fertility. Model results closely match the archaeological evidence in defined locations. On a broader scale, we calculate that the youngest island, Hawai'i, could have supported 572 km² of intensive agriculture, 97% as rain-fed dryland field systems, while Kaua'i, the oldest island, could have supported 58 km², all as irrigated wetland systems. Irrigated systems have higher, more reliable yields and lower labor requirements than rain-fed dryland systems, so the total potential yield from Kaua'i (49k metric tons) was almost half that of Hawai'i (97k metric tons), although Kaua'i systems required only 0.05 of the agricultural labor (8400 workers, versus 165,000 on Hawai'i) to produce the crops. We conclude that environmental constraints to intensive agriculture across the archipelago created asymmetric production efficiencies, and therefore varying potentials for agricultural surplus. The implications both for the emergence of complex sociopolitical formations and for anthropogenic transformation of Hawaiian ecosystems are substantial.

“You can make it here!”: Producing Europe’s mobile borders in the New Gambia

European border externalization to “sending states” throughout Africa is a well-documented phenomenon. Less clear, however, is the role that African governments and implementing organizations play in border externalization, nor the precise mechanisms by which European borders are “mobilized” (Szary & Giraut, 2015) and projected into everyday spaces in “sending states”. Drawing on a case study of three different European border enforcement projects in The Gambia, I argue that a collaboration between the International Organization for Migration, the EU Emergency Trust Fund for Africa, and the Gambian government makes Gambians themselves agents of the European border. Drawing upon Szary and Giraut's notion of “borderities” (2015), I illustrate how the border is projected into The Gambia through an articulation of humanitarian borderwork with developmental approaches intended to solve the “root causes of migration” (Zaun & Nantermoz, 2021). Furthermore, I argue that the Gambian government is not passive in the process of border externalization, but actively involved in interpreting and rearticulating European policies and narratives about migration. Following Adamson and Tsourapas' (2020) reworking of the “migration state” concept, I demonstrate the Gambian government's active interests in bordering its own citizens: simultaneously encouraging emigration for the sake of national “development” while immobilizing young Gambians as part of a broader strategy to cooperate with European states. This research illustrates both the immense value of a “borderities” approach to studying contemporary migration management, and the close association between borderwork and nationhood in African post-colonial states.     

Colonial encounters,local knowledge and the making of the cartographic archive in the Venetian Peloponnese

Current research on the cartography of the Venetian Empire rests on a state-centred perspective which reduces maps to mere technical tools in the service of maritime expansion and colonial government. In contrast, this paper argues that such an approach cannot sufficiently account for the multiple ethnocartographic transactions between Venetian authorities and local communities which defined Venetian map-making projects. Taking the seventeenth-century conquest of the Peloponnese as its focus, the paper proposes to rethink the Venetian cartographic archive as constituted through a set of socio-cultural and political practices involving both colonial surveyors and native inhabitants. By analysing the assemblage of cartographic knowledge in the context of the encounter between colonisers and colonised, the paper examines topographical surveys as the product of cross-cultural communication shaped through negotiation, competition and unequal dialogue. Ultimately, the paper aims to show the heuristic value of a dialogic approach to cartography for a better understanding of both the colonial society of the Venetian Peloponnese and the making of knowledge in Venice's overseas empire.     

江苏省流动人口分布的格局演变及其驱动因素——基于城乡建设用地的探讨

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。

明代河南土地丈量综述

有明一代,河南省曾进行了三次土地丈量活动：第一次在明初洪武年间,丈量出的土地数字仅是当时开垦的土地数,不能反映全省实有的土地数量。第二次在明中期嘉靖年间,是在一种错误思想的指导之下进行的,丈量之后又以“符合原额”为宗旨,大量进行了折亩活动,故丈量出的土地数字既不能反映当时河南省的开垦耕种数,也不能反映当时实有的土地数字。第三次是在明中后期万历年间进行的,指导思想明确,法令严格,方法得当,丈量出的土地数字既能反映当时河南省的开垦耕种数,又代表了全省实有的耕地数字。     

陶澍与包世臣关系探微

陶澍和包世臣是近代中国地主阶级改革派的核心骨干,嘉道年间经世致用思潮的主要代表。包世臣是陶澍的主要幕僚,他们开始突破“重农轻商”的传统观念,提出了“利商”的思想和政策;并共同设计了对漕运、盐务等有关国计民生大政的改革,他们所推行的海运、票盐更是改革派的主要成果。同时,他们对当时货币危机的原因、对禁烟运动和抗击外国侵略者,都有共同的认识,是中国近代杰出的爱国主义者。     

论明治宪法中议会预算审议权的形成

1889年的明治宪法是一部以天皇大权为中心的专制宪法,议会的权限有限,但是由于它被赋予了重要的预算审议权等财政权限,促使战前日本天皇制的政治体制中竞产生了政党政治。那么,宪法的缔造者——伊藤博文为什么会把这么重要的权力赋予议会？有学者认为,伊藤博文等人对“宪政及各类政体的精神”有着“深刻的理解”是重要原因。而本文则通过对近世以来日本地方上存在的租税协议惯行、明治维新后地方民会和府县会的预算审议权以及宪法发布前政府及民党的宪法草案内容等进行分析,认为议会拥有预算审议权等财政权限已是当时普遍的基本的认识,具有广泛的社会基础,伊藤博文不可能逆社会潮流而动也是重要的原因之一。
