Investigating rainfall oscillations, on a local scale, becomes necessary to expand the range of information and analysis of the relationship between agricultural production and the temporal cycles of droughts. In this context, the aim of this article is to analyze the relationship between the pattern of drought in recent years and dryland agriculture in municipalities in the semi-arid state of Pernambuco and possible contributions to an eventual desertification process. For the development of the study, annual rainfall patterns were generated between 2010-2019. Posteriorly, questionnaires were applied to 30 families of dryland and information on agricultural production in the municipalities was evaluated in public census databases to correlate, using Pearson's statistics, with rainfall patterns. Among the studied period, six years presented rainfall patterns that reflected drought characteristics. In agricultural production, the impacts were visible on perennial crops, but in census data, the relationship between rainfall patterns and agricultural production showed weak correlations. In animal husbandry, cattle were pointed out by farmers and census data as the most affected. The environmental and economic impacts of the dry season reflect likely contributions to an eventual desertification process if the rhythm and climatological patterns of rainfall occur in a similar way in the coming years.
