In 2018 when Jair Bolsonaro, a former military captain with extreme right-wing views, won the elections, the international arena was impatiently awaiting if he will fulfil the steps, he promised in his election programme. Bolsonaro promised to open up the Amazon for business in order to strengthen Brazil’s position in the world trade and improve the country’s economy overall. Since environmental security became a hot topic, Brazil has been an interest for researches in order to analyse the deforestation rates, its relation to the indigenous population and their effect on the proclaimed ‘lungs of the world’. This thesis aims to analyse the approach of Bolsonaro and his administration towards securitising the environment in Brazil. By using the Critical Discourse Analysis developed by Norman Fairclough, this study has analysed interviews with Bolsonaro and his ministers, the speech at the 74th opening of the United Nations, both the Proposal for Governance and the National Development Plan. The theoretical framework, based on the securitisation theory, has then been used to see whether the Bolsonaro administration has taken steps in order to securitise the environment. This study identifies that the language used in the analysed material does not hint at any attempts to securitise the Amazon. However, once placed into context, the analysis has found a shift within Bolsonaro’s rhetoric and mainly action which can be considered as the first steps towards securitisation. In conclusion, this thesis argues that the discourse of Bolsonaro is not prioritising the environment due to it being overshadowed by other issues such as public security. However, due to international pressure, there have changes which can lead to the securitisation in the future.
