Análise de Tendências de Precipitação e Temperatura nos Biomas do Estado da Bahia
As mudanças climáticas têm se tornado preocupação mundial. As florestas, com suas diversas fitofisionomias, desempenham papel crucial na regulação do clima da terra e as suas modificações podem provocar alterações nas variáveis climáticas, como precipitação, temperatura e umidade do ar nos mais diversos tipos de biomas. Diante disso, pretendeu-se com este estudo avaliar as tendências nos índices climáticos, como precipitação e temperatura e correlacioná-las com as mudanças no uso e cobertura florestal dos biomas presentes no estado da Bahia. Foram utilizados dados de temperatura média, máxima e mínima, além de precipitação total nos períodos chuvoso e seco, entre os anos de 1989 a 2019, obtidos a partir das estações meteorológicas presentes nos biomas estudados. Para a análise da cobertura da terra, foram usadas imagens do MapBiomas obter as tendências de mudanças nas variáveis climáticas aplicou-se o teste de Mann-Kendall. No bioma Mata Atlântica, foi observada uma leve tendência significativa na precipitação (p<0,05); já nos biomas Caatinga e Cerrado a tendência de mudança foi significativa (p<0,05) para a precipitação anual e para o período seco em alguns dos municípios analisados. A precipitação em Bom Jesus da Lapa apresentou correlação negativa significativa (-0,62) com a temperatura média anual, juntamente com mudanças significativas na cobertura florestal, apresentando alta correlação negativa com a conversão para pastagem e agricultura.

Este estudo investiga os efeitos combinados de diferentes lâminas de irrigação (LI) e da cobertura plástica nas culturas de tomate em regiões áridas, onde a otimização da água é crucial. Foram aplicadas cinco lâminas de irrigação, variando de 65% a 155% da evapotranspiração da cultura (ETc). Os resultados indicaram que o rendimento total, o peso médio dos frutos e o diâmetro (RT, PMF e DF) aumentaram com o incremento da LI, atingindo uma faixa ideal. A maior produtividade da água de irrigação (PA) foi alcançada com uma lâmina de irrigação de 305 mm ciclo⁻¹. A qualidade dos frutos melhorou sob LIs mais baixas, sugerindo potencial relação entre rendimento e qualidade sob estresse hídrico. A lâmina de 577 mm (~124% da ETc) maximizou a produtividade; para PA, 305 mm (65% da ETc). Considerando os resultados, a cobertura plástica não afetou significativamente a produtividade/qualidade (p>0,05), provavelmente devido à precipitação de 246 mm. Recomenda-se uma lâmina de 577 mm (~124% da ETc) para obter o máximo rendimento em condições semiáridas na Bahia; estudos futuros devem testar a cobertura em ciclos secos.

PRODUCTIVITY AND QUALITY OF TOMATO FRUITS UNDER SEMIARID CONDITIONS IN RESPONSE TO IRRIGATION AND PLASTIC MULCH 2 ABSTRACT Climate change poses a serious threat to water resources and agriculture, requiring innovative solutions to maintain food security. This study investigates the combined effects of different irrigation depths (ID) and plastic mulch on tomato crops in arid regions, where water optimization is crucial. Five irrigation depths were applied, ranging from 65% to 155% of crop evapotranspiration (ETc). The results indicated that total yield, average fruit weight, and diameter (TY, FW, and FD) increased with increasing ID, reaching an ideal range. The highest irrigation water productivity (IWD) was achieved with an irrigation depth of 305 mm cycle-1. Fruit quality improved under lower IDs, suggesting a potential relationship between yield and quality under water stress. The 577 mm depth (~124% of ETc) maximized productivity; for IWD, 305 mm (65% of ETc) maximized productivity. Considering the results, the plastic mulch did not significantly affect productivity/quality (p>0.05), probably due to the rainfall of 246 mm. A cycle of 577 mm (~124% of ETc) is recommended to obtain maximum yield under semi-arid conditions in Bahia; future studies should test the cover in dry cycles. Keywords: water management, water productivity, water stress, drip irrigation, Solanum lycopersicum L.

Dinâmica do uso e ocupação da terra e seu efeito na temperatura e na precipitação no bioma Caatinga (Floresta Tropical Sazonamente Seca) - Brasil
O objetivo deste trabalho foi avaliar a existência de influência da dinâmica do uso e ocupação da terra na Caatinga sobre a precipitação e temperatura. Para a determinação da temperatura, precipitação, número de dias sem chuva e áreas das classes, foi utilizada a plataforma Google Earth Engine. A precipitação foi avaliada pelo Índice de Anomalia de Chuva. As análises de tendência foram realizadas pelo teste de Mann-Kendall. Foi calculado o Coeficiente de Correlação de Pearson entre as variáveis climáticas e as classes de uso e cobertura da terra. A dinâmica do uso e ocupação da terra entre 1991 e 2020 demonstrou um avanço das áreas antropizadas. O número de dias consecutivos sem chuva, que entre 1981 e 1990 tinha seu maior valor em setembro, nas décadas posteriores foi observado em outubro. Para a temperatura foi observada uma tendência de aumento entre 1991 e 2020. Não foi possível estabelecer uma relação entre o uso e ocupação da terra e a precipitação. A redução da área ocupada pelas formações de maior porte aumenta a temperatura na região. A mudança do uso e ocupação da terra não afetou a precipitação na região, mas teve impacto direto na temperatura do ar.

Assessment of Land Desertification in the Brazilian East Atlantic Region Using the Medalus Model and Google Earth Engine
Many factors drive land desertification, especially in arid and semi-arid regions. However, the sheer number of these driving factors of desertification makes analyses computer-intensive. Cloud computing offers a solution to address this problem, especially in developing countries. The objective of this work was to assess the sensitivity of the East Atlantic Basin, Brazil, to desertification using the Mediterranean Desertification and Land Use (MEDALUS) model and Google Earth Engine (GEE). The model is composed of four environmental Quality Indices (QIs) associated with soil (SQI), vegetation (VQI), climate (CQI), and management (MQI), each encompassing factors that influence the desertification process. Digital databases corresponding to these factors were pre-processed and uploaded to GEE for analysis. We report Environmentally Sensitive Areas (ESAs) and Environmentally Critical Factors (ECF) maps of the East Atlantic Basin, which show that most of the basin is in either a critical (49.4%) or fragile (35.7%) state of sensitivity. In contrast, only a smaller portion of the area is unaffected (5%) or potentially affected (10.1%). The analysis also revealed an inverse correlation between desertification sensitivity and the presence of vigorous vegetation. A joint evaluation of ESAs and ECF shed light on the importance of each factor in the sensitivity to desertification. The East Atlantic Basin shows a high degree of sensitivity to desertification, thereby demanding more attention and the establishment of measures to mitigate the negative impacts of the desertification process.

Assessment of Land Desertification in the Brazilian East Atlantic Region using the Medalus Model and Google Earth Engine
Many factors drive land desertification, especially in arid and semi-arid regions. However, the numerous driving factors of desertification make analyses computer expensive. Cloud computing comes along to address this problem, especially in developing countries. The objective of this work was to assess the sensitivity of the East Atlantic Basin, Brazil, to desertification using the Mediterranean Desertification and Land Use (MEDALUS) model and Google Earth Engine (GEE). The model is composed of four environmental Quality Indices (QIs) associated with soil (SQI), vegetation (VQI), climate (CQI) and management (MQI), and contains factors influencing the desertification process. Digital databases of the factors were pre-processed and uploaded to GEE for analysis. We report Environmentally Sensitive Areas (ESAs) and Environmentally Critical Factors (ECF) maps of the East Atlantic Basin, which showed that most of the basin is in either critical (49.4%) or fragile (35.7%) state of sensitivity. In contrast, only a smaller portion of the area is unaffected (5%) or potentially affected (10.1%). Sensitivity to desertification was inversely correlated with the presence of vigorous vegetation. A joint analysis of ESAs and ECF shed light on the importance of each factor in the sensitivity to desertification. The East Atlantic Basin shows a high degree of sensitivity to desertification, thereby demanding more attention and establishment of measures to mitigate the negative impacts of the desertification process.

BIOMASS OF TWO Eucalyptus CLONES (E. grandis × E. urophylla) IRRIGATED WITH SALINE WATER
Using saline water for irrigation relies on strategies that include selecting salt-tolerant cultivars and leaching salts away from zones close to the roots. A greenhouse experiment was carried out to assess early growth and biomass production of two Eucalyptus clones (E. grandis × E. urophylla), CO 865 and CO 1407, irrigated with saline water and under different leaching fractions. Treatments were laid out in a randomized block design and arranged in a 4 × 2 + 2 factorial scheme: four leaching fractions (3, 10, 20, and 30 % of crop water demand for plants irrigated with saline water), two Eucalyptus clones (VCC 865 and CO 1407), and two additional treatments, one for each clone, conventionally irrigated with fresh water. The treatments were replicated four times. Measurements were made at 114 days after transplanting. Soil salinity decreased with increasing leaching fraction where VCC 865 was grown; however, leaf dry weight production was lower in treatments irrigated with saline water. Compared to fresh water-irrigated plants, irrigation with saline water resulted in lower: canopy diameter, leaf number, dry leaf mass, dry root mass, aerial parts dry mass, aerial part/root ratio, and total plant dry weight. Overall, the VCC 865 Eucalyptus clone performed better under saline irrigation than CO 1407.

Morphophysiology and quality of yellow passion fruit seedlings submitted to inhibition of gibberellin biosynthesis
The aim of this study was to verify if a growth reduction of yellow passion fruit seedlings’ growth morphophysiology and quality could be changed by paclobutrazol applied through seedling immersion. The experiment was conducted in a greenhouse, with seedlings grown in polyethylene tubes (290 cm3), with substrate. At 40 days after sowing, the seedlings were immersed in an aqueous solution of paclobutrazol at concentrations of 0, 50, 100, 150, and 200 mg L-1. The experiment was conducted in a randomized block design, with five treatments (paclobutrazol concentrations) and four replicates. At 15 and 30 days after treatment, growth characteristics were evaluated. At the end of the assay, destructive evaluations related to mass determination, total leaf area, and seedling quality index were performed. Paclobutrazol treatment induced restrictions in seedling growth, except for fresh and dry mass of root and total fresh mass. Based on these characteristics, the increase in values induced by paclobutrazol was verified. The seedling quality, defined by the major value of the Dickson quality index and a smaller robustness index, was higher when submitted to paclobutrazol treatment.

Aplicação do modelo MGB-IPH na bacia hidrográfica do Rio Pardo em diferentes cenários de uso e ocupação do solo
As alterações causadas pela ação do homem ao meio ambiente podem influenciar a disponibilidade de água em bacias hidrográficas, e mensurar os impactos causados por essa ação é imprescindível para a tomada de decisões por órgãos gestores. Dessa forma, o objetivo deste estudo foi realizar a calibração e validação do modelo MGB-IPH para simular o comportamento da vazão na bacia hidrográfica do rio Pardo em diferentes cenários de uso e ocupação do solo. Para isso, foram usadas informações de uso e ocupação do solo que revelaram que a bacia hidrográfica em estudo teve uma redução em sua área de floresta e aumento das áreas dedicadas às atividades agropecuárias, entre os anos de 2001 e 2016. Com essas informações acerca da bacia e com os dados climáticos e os tipos de solos disponíveis, foram realizadas a calibração e a validação do modelo, que teve seus desempenhos verificados. As mudanças nas vazões mensais médias, totais, máximas e mínimas simuladas pelos diferentes cenários foram comparadas por meio de teste de média para amostras dependentes e avaliação das vazões anuais máximas, médias e mínimas dos valores testados. O MGB-IPH foi validado de forma satisfatória para a estação 53880000 da Agência Nacional de Águas, tendo problemas de subestimativa de picos de vazões máximas, porém conseguindo representar adequadamente os dados observados em termos da sazonalidade das vazões, da diferenciação de anos mais úmidos e anos mais secos, e dos picos de cheias de média e pequena intensidade. O modelo foi sensível ao identificar o impacto das mudanças do uso e ocupação do solo nas vazões simuladas para a bacia hidrográfica do rio Pardo, com o cenário de 2016 apresentando maiores valores de vazões mensais médias, totais, máximas e mínimas que as encontradas no cenário de 2001.

MORPHOLOGY OF PARDO RIVER WATERSHED AT THE BORDER OF THE STATES OF BAHIA AND MINAS GERAIS
The spatial analysis of watersheds, as well as the evaluation off the changes occurring in their catchment area along the time are essential for the qualification of environmental changes. This study aims to characterize morphometrically the Pardo river watershed, as well as to evaluate the changes in soil use and occupation occurring between 2001 and 2016. The morphometric analysis consisted of the determination of the geometric parameters, relief information and drainage network using Geographic Information Systems. The land use and occupation information was collected through data from the online mapping platform of the Brazilian Mapping and Land Use Mapping (MapBiomas). According to the results, morphometry indicated that the watershed has low propensity to flood occurrence and tendency to conservation; great part of its area is between 600 and 1000 m of altitude, with predominance of undulating and soft-undulating slopes. The analysis of land use and occupation showed that the area devoted to agricultural activities increased during the period evaluated and occupies most of the basin, while the area of ??forests was reduced, the second in size, and these two classes occupy more than 96 % of catchment area.
