摘要

气候变化已经影响到地球上的生命，必须采取缓解措施，这需要适当地确定最易受这些变化影响的区域。本研究评估了气候变化对巴西半干旱区Caatinga生物群系的水分有效性(水分过剩、水分亏缺和降水减去蒸散)和气候分类的影响。考虑当前情景(1961 - 2015年的历史序列)，采用Thornthwaite & Matther(1955)的水平衡模型，得到水盈余和水亏;考虑到辐射强迫为4.5 wm -2 (RCP4.5)的代表性浓度路径(RCP)的乐观情景

Implications of climate change on water availability in a seasonally dry tropical forest in the Northeast of Brazil

Climate change is already affecting life on Earth and mitigation measures must be taken, which require proper iden - tification of the regions most vulnerable to these changes. This study assesses the impact of climate change on water availability (water surplus, water deficit and precipitation minus evapotranspiration) and climate classification across the Caatinga biome, located within the Brazilian semiarid region. To obtain the water surplus and water deficit, the water balance of Thornthwaite & Matther (1955) was applied considering the current scenario (historical series from 1961 to 2015); the optimistic scenario, considering the Representative Concentration Pathway (RCP) for a radiative forcing of 4.5 W.m -2 (RCP4.5), i

期刊介绍： Ceres Journal is a journal bimonthly published by Universidade Federal de Viçosa (Federal University of Viçosa - UFV). It is intended for the publication of unpublished scientific papers, with technical and scientific relevance, resulting from studies related to innovations and solutions to the problems of agriculture, with emphasis on tropical-related studies. Ceres publishes papers ni: -Plant production -Soil and plant nutrition -Plant breeding applied to agriculture -Plant Health -Physiology and morphology applied to agriculture -Vegetative and seminiferous propagation -Agricultural Engineering (specifically: Irrigation and Drainage; Soil Physics; Agrometeorology; Precision ---Agriculture; Technology and Application of Pesticides) -Animal production and health applied to agriculture
