RESUMO:

The production of sea salt in Rio Grande do Norte has contributed significantly to the social and economic development of the State, creating jobs, increasing incomes and adding to the public revenue through taxes. Climatic conditions that favor this activity are observed in regions of low latitude characterized by high temperatures and constant winds, as well as low precipitation. Thus, as the production of sea salt depends on climate conditions, the aim of this thesis is to analyze, statistically, how the influences of the climate variability and changes affect the production of this mineral. To this end, the thesis comprises four articles. In the first article, the main objective was to analyze the correlation between these climatic variables and the production of sea salt, as well as estimate the intensity with which the volume of this mineral varies as a result of climate change in the city of Macau, RN. The results show positive correlations between the volume of sea salt production and the temperature, hours of sunlight, evaporation and wind speed, and negative correlations with precipitation and relative humidity. In relation to climate changes, findings showed an increase in the volume of sea salt in four scenarios of climate change, which were presented by the IPCC, in the city of Macau, RN. Results showed that the best scenario for the salt industry proved to be solar evaporation at a rate of RCP8.5. In the second article, the main objective was to analyze the influence of the ENSO on sea salt production in RN. The results showed positive and statistically significant associations with the El Niño phenomenon. In relation to La Niña, the results do not show statistically significant associations with this phenomenon, regarding the production of sea salt in RN. In the third article, the main objective was to estimate the impact of climate change on the volume of sea salt produced in Rio Grande do Norte. The results showed positive impacts on the volume of sea salt produced in the four scenarios of climate change. In the scenario with less carbonic gas emissions, the positive impact, in relation to the average in the period studied, will be from 9.1227%  in the RCP2.6 scenario to 16.5350% in the RCP8.5 scenario, making it possible to affirm that the climate changes projected by the IPCC will have a positive impact on the production of sea salt. In the fourth article, the main objective was to estimate the economic impact of climate change on sea salt production. The results showed that climate changes will generate a positive impact on the income from sales in the sea salt industry in RN, in all of the climate change scenarios. The average annual increase in income from sales in this industry is estimated at varying from 9.1227% in scenario RCP2.6 to 16.5350% in scenario RCP8,5, making it possible to affirm that the sea salt industry in RN will benefit, economically, from climate changes.
