“…Studies of change in land use and climate at regional and local scale are best suited and furnish insight to water resources planner. Numerous studies have been conducted in perspective of hydrological variables response to LULC and climate variability in a watershed using SWAT model (Mehdi et al 2015;El-Khoury et al 2015;Mishra et al 2017;Yu et al 2018;Bal et al 2021;Bekele et al 2021;Chiang et al 2021;Lopes et al 2021;Sinha et al 2021;Teklay et al 2021).…”

Land use/cover (LULC) and climate are significant environmental factors that influence watershed hydrology across the globe. The present study attempts to understand the consequences of existing changing patterns of climate and LULC on the hydrology of the Usri watershed. Different water balance components were simulated using a semi-distributed Soil and Water Assessment Tool (SWAT) model. Sixteen scenarios were generated using combinations of four periods of climatic data (1974–84; 1985–1995; 1996–2006 and 2007–2016) and four sets of land use maps (1976; 1989; 2000 and 2014). The SWAT model performed well for monthly stream flows during calibration and validation. The study finds that the individual impact of LULC change contributes to increase in the streamflow and decrease in evapotranspiration (ET) primarily due to increase in urbanization and decrease in water bodies, forest cover and barren land of Usri watershed. The combined impact of climatic variations and land use change reveals complex interactions. The study provides insight into hydrological response to variations in climate and land use changes in Usri watershed in recent decades. The results of this study can be beneficial to the authorities, decision-makers, water resource engineers and planners for the best water resource management approaches in the perspective of climate change and LULC transformation of similar ecological regions as that of Usri.

O processo de expansão da Palma de Óleo na Amazônia foi possibilitado pelas condições edafoclimáticas e de ocupação do espaço rural amazônida, o artigo presente traz como objetivo expor a relação da mudança de uso e ocupação da terra e a expansão da Palma de Óleo na Amazônia Oriental, dessa forma metodologicamente se utilizou, principalmente, de imagens de satélite Landsat 07 e 08, para os anos de 2002 e 2020, sendo adotadas classes para a melhor compreensão das diferenças de ocupação do solo entre estes dois períodos, adotando-se 10 classes. Os resultados demonstram que houve um crescimento de 321% relacionado à ocupação da Palma, e que aproximadamente 30% da conversão se deu de territórios que já foram ocupados por atividades agropecuárias e solo exposto por outras atividades, também se traz um quadro que expõe políticas e ferramentas que podem auxiliar na compreensão da expansão dessa monocultura. Concluiu-se que o histórico de ocupação dos municípios pode se diferir, porém a ocupação pela palma pode ser analisada de forma una, como foi feito neste estudo e, além disso, um trabalho síncrono entre as diferentes esferas de interesse em torno da expansão da Palma pode levar a resultados menos danosos ao ambiente inserido e ao social impactado.O processo de expansão da Palma de Óleo na Amazônia foi possibilitado pelas condições edafoclimáticas e de ocupação do espaço rural amazônida, o artigo presente traz como objetivo expor a relação da mudança de uso e ocupação da terra e a expansão da Palma de Óleo na Amazônia Oriental, dessa forma metodologicamente se utilizou, principalmente, de imagens de satélite Landsat 07 e 08, para os anos de 2002 e 2020, sendo adotadas classes para a melhor compreensão das diferenças de ocupação do solo entre estes dois períodos, adotando-se 10 classes.

The dynamics of oil palm expansion - elaeis guineensis jacq in an eastern Amazonian territory A B S T R A C TThe process of expansion of oil palm in the Amazon was made possible by the edaphoclimatic conditions and situation of the occupation of the Amazonian rural space. This article aims to expose the relation between the changes in land use and occupation and the expansion of the oil palm in the Eastern Amazon. Thus, methodologically, mainly Landsat 07 and 08 satellite images were used, for the years 2002 and 2020, with the adoption of classes to better understand the differences in land occupation between these two periods; 10 classes were adopted. The results show that there was a growth of 321% related to the occupation of oil palm, and that approximately 30% of the conversion took place in territories that were already occupied by agricultural activities and soil exposed by other activities. The research also indicates policies and tools that can assist in understanding the expansion of this monoculture. It was concluded that the history of occupation of the towns may differ; however, the occupation by the oil palm can be analyzed in a unified way, as done in this study, and, in addition, a simultaneous joint work of the different fields of interest on the expansion of palm can lead to less harmful results to the inserted environment and the impacted social group.Key Words: land use change, geotechnologies, northeast of Pará.

“…In particular, land cover change is a dominant factor affecting ecosystems [11,12] and the hydrological regime [13]. For example, Lopez et al [14] detected that forest conversion to agriculture use has directly affected the surface runoff and groundwater contribution of the Upper Teles Pires (Brazil). Zhang et al [15] evidenced that the watershed size influences the sensitivity of annual runoff to forest cover change and that annual runoff is more sensitive to forest cover change in water-limited watersheds than in energy-limited watersheds.…”

A persistent precipitation deficiency (meteorological drought) could spread to surface water bodies and produce a hydrological drought. Meteorological and hydrological droughts are thus closely related, even though they are separated by a time lag. For this reason, it is paramount for water resource planning and for drought risk analysis to study the connection between these two types of drought. With this aim, in this study, both meteorological and hydrological drought were analyzed in the Wadi Ouahrane Basin (Northwest Algeria). In particular, data from six rainfall stations and one hydrometric station for the period 1972–2018 were used to evaluate the Standardized Precipitation Index (SPI) and the Standardized Runoff Index (SRI) at multiple timescales (1, 2, 3, 4, …, 12 months). By means of a copula function, the conditional return period for both types of drought was evaluated. Results evidenced that runoff is characterized by high level of temporal correlation in comparison to rainfall. Moreover, the composite index JDHMI (Joint Deficit Hydro-meteorological Index) was evaluated. This index is able to reflect the simultaneous hydrological and meteorological behavior at different timescales of 1–12 months well and can present the probability of a common hydrological and meteorological deficit situation more accurately and realistically compared to precipitation or runoff-based indicators. It was found that, over the analyzed basin, the average severity of combined hydro-meteorological drought (JDHMI) was 10.19, with a duration of 9 months and a magnitude of 0.93.
