A B S T R A C TThe spatial-temporal distribution of rainfall is an important regional feature. The knowledge of this characteristic provides guides to decisions regarding the necessary measures to minimize the damages caused by the irregularity of the rains. The high vulnerability to which the Brazilian Northeast is exposed due to the climatic instability generates a picture of the destruction of plantations, unemployment, and hunger. The study aimed to characterize and analyze climatically the precipitation behavior, its impacts and how participatory management works for the Capibaribe river basin, as support for public policies, to minimize the impacts generated. The study was conducted in the catchment area of the Capibaribe river. The pluviometric data obtained through pluviographs located in three meteorological stations were made available (APAC) for the years 1970 to 2016. It was evidenced the high temporal and spatial variability of the rains within the same basin. In which the highest rainfall indexes are found for the metropolitan region of Recife and the lowest rainfall index for the station located in Frei Miguelinho. The total precipitated blade for the station located in Recife was 86486.3, Vitória de Santo Antão was 49328.7, and Frei Miguelinho was 28566.9. The months of January to March presented the lowest precipitation rates, whereas during April to July the highest precipitation level of high intensity and short length occurs, resulting in a high risk of soil loss, environmental impacts and metropolitan region of Recife. Keywords: Variability, environmental impacts, precipitation. R E S U M OA distribuição espaço-temporal das chuvas é uma característica regional importante. O conhecimento dessa característica orienta decisões quanto às medidas necessárias para minimizar os danos decorrentes da irregularidade das chuvas. A elevada vulnerabilidade a que está exposta o Nordeste brasileiro em decorrência da instabilidade climática gera um quadro de destruição de plantações, desemprego e fome. O estudo objetivou caracterizar e analisar climaticamente o comportamento das precipitações, seus impactos e como funciona a gestão participativa para a bacia hidrográfica do rio Capibaribe, servindo de suporte para políticas públicas, afim de minimizar os impactos gerados. O estudo foi conduzido na bacia hidrográfica do rio Capibaribe. Os dados pluviométricos obtidos através dos pluviógrafos localizados em três estações meteorológicas foram disponibilizados (APAC) para os anos de 1970 a 2016. Evidenciou-se a elevada variabilidade temporal e espacial das chuvas dentro de uma mesma bacia hidrográfica. Em que os maiores índices pluviométricos são encontrados para a região metropolitana do Recife e o menor índice pluviométrico para a estação localizada em Frei Miguelinho. O total da lâmina precipitada para a estação localizada no Recife foi de 86486,3, Vitória de Santo
