Full Professor at the Federal University of Pernambuco (UFPE), Josiclêda Domiciano Galvíncio has a well-established academic trajectory in the fields of climatology, remote sensing, climate change, and hydrological modeling. She holds a degree in Mathematics from the State University of Paraíba (1996), a master’s degree in Meteorology (2000) from the Federal University of Paraíba, and a Ph.D. in Natural Resources (2005) from the Federal University of Campina Grande. She completed a postdoctoral fellowship at Texas A&M University (USA) between 2013 and 2014, focusing on forest monitoring using LIDAR, strengthening her international engagement and her work in geotechnologies applied to the environment.
At UFPE, she coordinates the Remote Sensing and Geoprocessing Laboratory, conducting research on water dynamics, environmental planning, and climate vulnerability in ecosystems such as the Caatinga, Atlantic Forest, and mangroves. She is a permanent member of academic and professional graduate programs (master’s and doctorate), including ProfÁgua – the National Professional Master’s Program in Water Resources Management and Regulation – and supervises interdisciplinary projects aimed at the integrated management of natural resources.
She leads major research projects funded by CNPq, CAPES, FACEPE, and the Ministry of Cities. Creator of SUPer – the Hydrological Response Unit System for Pernambuco, based on the SWAT model – she is also involved in the development of BEST – Brazilian Ecohydrological Simulation Tool, focused on climate and hydrological simulation in semi-arid areas. She coordinates the CAPES Special Visiting Professor project with researcher Charles Allan Jones (Texas A&M University), expanding international scientific cooperation.
She is Editor-in-Chief of the Revista Brasileira de Geografia Física and the Journal of Hyperspectral Remote Sensing, and a reviewer for prominent journals such as Journal of Hydrology, Ecological Modelling, and Revista Árvore. Her scientific production is extensive, with numerous articles published in high-impact indexed journals, addressing topics such as water balance, land use and land cover, El Niño, environmental degradation, and watershed management.Her academic and institutional contributions are highly impactful. She coordinated the SWAT Brazil Conference 2014, in partnership with Texas A&M University, and the traditional Workshop on Climate Change and Water Resources of Pernambuco. In 2024, she received the CAPES Thesis Award, one of the highest distinctions in Brazilian graduate education, recognizing her excellence in training researchers and developing knowledge with high socio-environmental impact.

Climate change, greenhouse gases, global warming, and their potential effects have shown in numerous debates and studies that human activities are identified as one of the major causes of climate change. In Brazil, the Semi-arid region could be one of the most impacted by climate changes, and the predominant vegetation in this region, the Caatinga, is significantly modified throughout the year due to high climate variability. In this context, the aim of this research is to evaluate the estimates of Gross Primary Productivity (GPP) and Net Primary Productivity (NEE) in four predominant species of the Caatinga biome. Observational data were collected in the field with a spectroradiometer from the canopy of a Caatinga area in Petrolina, PE, and the models for Gross Primary Productivity and Net Primary Productivity were applied. The results indicated that, on average, the Caatinga canopy shows lower GPP and NEE compared to the dominant species, with values of 1.79 g C m⁻² d⁻¹ and 1.72 g C m⁻² d⁻¹, respectively. The species with the highest estimates for GPP and NEE were Samanea tubulosa and Sapium argutum, with GPP values of 3.54 g C m⁻² d⁻¹ and 3.47 g C m⁻² d⁻¹, and NEE values of 2.64 g C m⁻² d⁻¹ and 2.84 g C m⁻² d⁻¹. The use of spectroradiometers allowed for the observation of specific carbon flux responses, enabling the assessment of how Gross Primary Productivity and Net Primary Productivity vary among different species.
