旱灾一直是我国的主要自然灾害之一,它影响粮食安全、饮用水安全、生态安全。面对大旱,我们必须深刻反思我国现有抗旱立法工作的不足之处,并通过加强防灾减灾与水资源管理方面立法,完善《森林法》的内容,加快制定农业保险法、农田水利法等农业立法,使我国抗旱工作有法可依,提高我国应对旱灾的能力。 相似文献

The purpose of this article is to analyse one of the very first European-level instances of trade union and social movement interaction in defence of the public sector, namely, the Coalition for Green and Social Procurement, an alliance of European trade unions and green and social non-governmental organisations (NGOs), and its campaign for an amendment of the new public procurement directives from 2000 to 2003. It will be examined to what extent this campaign was able to change the directives and counter neoliberal restructuring effectively as well as what the possibilities but also limits of trade union and social movement cooperation are as exemplified in this particular case study. 相似文献

In the conflict between Bedouin representatives and government authorities in the southern Israeli Negev, the term ‘insurgent building’ refers to the construction of buildings erected in the full expectation that they will be demolished by the Israeli police shortly thereafter. This article analyses how insurgent building is employed as a spatial practice by emerging political actors to claim contested Bedouin landownership. Importantly, insurgent building relies on the ability of media and advocacy organizations to mobilize behind the issue. Most of the relevant scholarship takes the interpretative categories advanced by these actors at face value. Following anthropological debates regarding objectification and categorization, I examine the context of a specific case of insurgent building. Emerging political actors who employ insurgent building often rely on predefined ethnic categories and clear‐cut people–state polarities. This case demonstrates the need for a more differentiated understanding of multilayered local dynamics than the one offered by mainstream linear interpretations. At a more abstract level, political actors contribute to the reproduction of the very categories against which they mobilize. 相似文献

This article presents the analysis of two dominant anti-consumption discourses (the voluntary simplicity discourse and the culture jammer discourse) to show the importance of anti-consumption practices in the construction of consumer identities. Specifically, two consumer-resistant identities are presented: a hero identity and a project identity. Each resistant identity is produced by, and produces, overreaching cultural discourses against consumer culture, namely resistance to exploitative consumption and resistance to positional consumption. In addition, each identity expresses resistance either in terms of political consumption for an outer change or in terms of creative consumption directed toward an inner change. By stressing the importance of hero resistant identities and project resistant identities, this article offers the concept of identity formation as central rather than peripheral to the development of consumer resistance. 相似文献

Sowing phases of French serradella (Ornithopus sativus Brot.) pasture between extended cropping sequences in the Western Australian wheatbelt can sustain grain production through restoring soil fertility and reducing selective herbicide use. The objective of this article is to investigate the profitability of rotations involving this pasture under a variety of weed management scenarios to obtain greater insight into its value for mixed farming systems in this region. A stochastic search procedure, compressed annealing, is used to identify profitable sets of weed management strategies in a simulation model representing a large number of potential combinations of chemical and non‐chemical forms of weed control. In contrast to a continuous‐cropping sequence, the inclusion of a serradella phase in a rotation is profitable at high weed densities and with increasing levels of herbicide resistance. A single year of pasture in the rotation is optimal if resistance to Group A selective herbicides is present at the beginning of the planning horizon, but a three‐year phase is required if resistance to multiple herbicide groups is observed. Sowing a serradella pasture twice over a two‐year phase is also shown to be economically attractive given benefits of successive high weed kills. 相似文献

We analyze a monopolist's incentive to innovate a new antibiotic which is connected to the same pool of antibiotic treatment efficacy as is another drug produced by a generic industry. We outline the differences of antibiotic use under market conditions and in the social optimum. A time- and state-dependent tax-subsidy mechanism is proposed to induce the monopolist and generic industry to exploit antibiotic efficacy optimally. 相似文献
