"Os Conflitos ambientais em Portugal (1974-2015): uma breve retrospectiva"

In this chapter, the authors made a survey of the research undertaken by social scientists and their reflections on environmental conflicts in Portugal. In these, a critical discourse has emerged concerning, on the one hand, the weak public environmental awareness, and, on the other, the progressive obliteration of environmental movements and their institutionalization throughout the creation of different environmental groups and the incorporation of the “environment” in legislation and in political discourse. In a brief retrospective, we review several conflicts taking into account different relevant factors: level of mobilization, media attention received, organization, impact, and ideological reference they have had in Portugal since the seventies. We have particularly highlighted the movement against nuclear energy and the construction of dams, the pollution caused by intensive breeding, the expansion of eucalyptus plantations, the conflicts against “wild” forms of mining, the business of toxic waste, the expansion of the economy of the concrete, the installation of landfills, and the defense of the natural heritage. This survey has considered three periods: the 1970s, marked by the emergence and performance of ecological movements of different ideological extraction; the second half of the 1980s, marked by the institutionalization of the environment and the imposition of a new legal framework with impact on environmental policies resulting from the integration into the European Economic Community; and finally, a third period, from the 1990s to present, marked by increasing environmental media coverage, with a particular emphasis on environmental conflicts in a context of an increasing liberalization of economic activities and the expansion of extraction and of the concrete economy. This is also the period where the environment emerges in disputes over the uses of the territory as economic and asset value. Most of these conflicts arise from the activities of local agents or national environmental groups that quickly gain strong local roots and sometimes even have some success. However, their impact on the national and Community legislation seems to be less relevant.

Genetic diversity of Bursaphelenchus cocophilus in South America

Molecular characterisation of Bursaphelenchus cocophilus, the causal agent of ‘red ring disease’, is imperative for efficient identification procedures in Brazil and Colombia, because quarantine species such as B. xylophilus and B. mucronatus are already listed in both countries. ITS-1/2 region and D2-D3 segment of LSU rDNA were used to characterise isolates of B. cocophilus obtained from coconut plantations in Brazil and Colombia. Results from ITS-1/2 and LSU rDNA regions showed that all isolates of B. cocophilus from Brazil and Colombia formed a monophyletic group. The LSU rDNA region indicated that all isolates formed a single monophyletic group with high Bayesian posterior probability (100%). This is the first study on ITS-1/2 for the characterisation of B. cocophilus populations. A species-specific primer was designed for identification of B. cocophilus.
