This article presents the local gender contract of a smallholder irrigation farming community in Sibou, Kenya. Women's role in subsistence farming in Africa has mostly been analyzed through the lens of gender division of labor. In addition to this, we used the concept of ‘local gender contract’ to analyze cultural and material preconditions shaping gender-specific tasks in agricultural production, and consequently, men's and women's different strategies for adapting to climate variability. We show that the introduction of cash crops, as a trigger for negotiating women's and men's roles in the agricultural production, results in a process of gender contract renegotiation, and that families engaged in cash cropping are in the process of shifting from a ‘local resource contract’ to a ‘household income contract.’ Based on our analysis, we argue that a transformation of the local gender contract will have a direct impact on the community's adaptive capacity climate variability. It is, therefore, important to take the negotiation of local gender contracts into account in assessments of farming communities' adaptive capacity.  相似文献

While the regional resilience approach stresses major place-specific factors of adaptability to economic crises, industry-sector-specific mechanisms of shock response, which often cross-regional boundaries, still require conceptualization relating to aspects of resilience. This paper proposes the concept of sectoral resilience, which acknowledges that the actors who constitute the value chains and production systems of an industry sector, when struck by a major global crisis, collectively and interactively form a sector-specific pattern of response and adaptation. As these actors often strategically use assets at different locations, industry-specific spatial patterns of adaptation emerge that affect various regions in differing ways. After defining the suggested concept and related terminology, its geographical logics are outlined. Then major conceptual pillars of sectoral resilience are depicted, relating to six major, partly interdependent process fields. For each of them, mechanisms of shock adaptation of an industry sector and major factors of inter-sectoral distinctions of resilience patterns are pointed out, briefly illustrated by the examples of the automotive and mechanical engineering sectors. The approach helps us better understand industry-specific features of crisis adaptation and intersections of regional and corporate logics of resilience.  相似文献

The lead isotope composition of 22 samples from the excavation of the Phoenician site of La Fonteta (Guardamar del Segura, Alicante, Spain) has been analysed in a preliminary study of their provenance. These materials span chronologically from the first half of the 8th century BC to the middle of the 6th century BC.The samples have been selected to include materials used in lead and silver production, as well as in copper-based metallurgy. Therefore, lead droplets, galena nodules and fragments of litharge have been analysed, together with a fragment of a copper ingot, an object, a melting waste composed of a Cu–Pb alloy, and two fragments of a material that we have provisionally labelled ‘Pb–Cu cupellation debris’.All these materials have been initially analysed by X-Ray Fluorescence-Spectrometry to identify their bulk compositions. Some of them have been also analysed by SEM–EDX and ICP–OES. Subsequently, lead isotope analyses (LIA) have been performed using Thermal Ionization Mass Spectrometry (TIMS). The new LIA data obtained has been compared with published lead isotope data from the Mediterranean area. The identification of different groups suggests a significant complexity of the internal and external trade routes during the Orientalising period. For this reason, the provenance study of these materials is especially important in shedding light on the commercial dynamics that the Phoenicians established with native people to control the raw materials and to commercialise finished products.  相似文献

Currently, several theoretical concepts emphasise the importance of socially embedded collaboration for innovation driven regional development. For instance, the notions of innovative milieu and social capital both focus on this factor of economic success. This raises the question of whether they should be regarded as redundant or complementary, the latter case allowing their purposive combination. This article supports the second view and discusses significant distinctions between the two notions, apart from consistencies. The example of the German 'technology region' of Aachen, which has been undergoing substantial industrial restructuring based on regional collaboration, serves to underpin the theoretical arguments.  相似文献

This counter‐mapping project illustrates the areas of intervention of different operations geared toward rescue and enforcement between 2013 and 2015, including the Italian Navy's “Mare Nostrum” search and rescue mission, the EU border agency Frontex's “Triton” enforcement operation, the humanitarian interventions of commercial vessels, and the action of civil‐society rescue vessels such as those operated by Médecins Sans Frontières (MSF—Doctors Without Borders). The project offers a spatial understanding of the Mediterranean border‐scape, the practices of rescue and enforcement that occur within it, and the risk of sea‐crossing at this particular moment. Through these maps, the Central Mediterranean Sea emerges as a striking laboratory from which novel legal arrangements, surveillance technologies, and institutional assemblages converge.  相似文献

The conversation between Étienne Balibar and Nicholas De Genova engages with the Mediterranean of migration as a multifaceted, productive, and contested space, which can represent a counterpoint to a deep‐rooted Eurocentric imaginary. Looking at the Mediterranean as a space produced by the mobility of the bodies crossing it and by the combination of different struggles, Balibar and De Genova comment on some of the political movements that have taken center stage in the Mediterranean region in the past few years and suggest that the most important challenge today is to mobilize a “Mediterranean point of view” whereby the political borders of Europe and its self‐centered referentiality can be challenged.  相似文献

This paper engages with the military‐humanitarian technology of migration management from the vantage point of the European Union Naval Force Mediterranean (EUNAVFOR MED) “Operation Sophia”, the naval and air force intervention deployed by the EU in the Central Southern Mediterranean to disrupt “the business model of human smuggling and trafficking” while “protecting life at sea”. We look at the military‐humanitarian mode of migration management that this operation performs from three vantage points: logistics, with a focus on the infrastructure of migrant travels; subjectivity, looking at the migrant profiles this operation works through; and epistemology, building on the mission's first stage of intelligence and data gathering. Through this multi‐focal approach, we illuminate the productivity of this military‐humanitarian approach to the migration crisis in the Mediterranean.  相似文献

These conversations between Toni Negri and Sandro Mezzadra (November 2014–October 2015) focus on the politics of Mediterranean boundaries and situate migratory movements across the Mediterranean in the geopolitical context of the Eastern and Southern shore. Looking at the proliferation of wars around the Mediterranean region and reflecting on the legacy of the Arab Uprisings, Mezzadra and Negri revisit the concept of the “autonomy of migration” and critically interrogate its possible contribution to the field of migration and in terms of the current refugee crisis.  相似文献
