“…The surface albedo was calculated as a function of the multispectral reflectance bands, using weight coefficients suggested by Tasumi et al [40]. The coefficients for the MODIS sensor are determined based on solar radiation at the surface, specifically for use in operational energy balance applications, representing each of the seven MODIS bands.…”

Burns are common practices in Brazil and cause major fires, especially in the Legal Amazon. This study evaluated the dynamics of the fire foci in the Legal Amazon in Brazil and their consequences on environmental degradation, particularly in the transformation of the forest into pasture, in livestock and agriculture areas, mining activities and urbanization. The fire foci data were obtained from the reference satellites of the BDQueimadas of the CPTEC/INPE for the period June 1998–May 2022. The data obtained were subjected to descriptive and exploratory statistical analysis, followed by a comparison with the PRODES data during 2004–2021, the DETER data (2016–2019) and the ENSO phases during the ONI index for the study area. Biophysical parameters were used in the assessment of environmental degradation. The results showed that El Niño’s years of activity and the years of extreme droughts (2005, 2010 and 2015) stand out with respect to significant increase in fire foci. Moreover, the significant numbers of fire foci indices during August, September, October and November were recorded as 23.28%, 30.91%, 15.64% and 10.34%, respectively, and these were even more intensified by the El Niño episodes. Biophysical parameters maps showed the variability of the fire foci, mainly in the south and west part of the Amazon basin referring to the Arc of Deforestation. Similarly, the states of Mato Grosso, Pará and Amazonas had the highest alerts from PRODES and DETER, and in the case of DETER, primarily mining and deforestation (94.3%) increased the environmental degradation. The use of burns for agriculture and livestock, followed by mining and wood extraction, caused the degradation of the Amazon biome.

“…Além das condições do clima semiárido, com destaque para o aumento do déficit hídrico, a região Nordeste do Brasil é ameaçada pela degradação ambiental devido a elevada pressão antrópica, por meio da atividade agropecuária, com ênfase no setor pecuário, havendo degradação do bioma Caatinga (Silva et al, 2021). Neste contexto, pode se observar a substituição da paisagem nativa por espécies forrageiras para formação de pastagem, a fim de garantir a alimentação animal durante todo o ano, devido a demanda imposta pela atividade predominante da região semiárida brasileira (Silva et al, 2020c).…”

O sucesso do agronegócio no setor pecuário, depende da oferta de forragem para os animais, especialmente em zonas semiáridas, onde as características climáticas e a baixa disponibilidade de alimento podem dificultar a atividade. Diante disso, o uso de práticas agrícolas que melhorem a resiliência agrícola dos cultivos e possibilitem a oferta de forragem durante todo o ano para os animais torna-se imprescindível. Dentre tais práticas, destacam-se: o uso de espécies adaptadas as condições climáticas, escolha da configuração de cultivo, a densidade de plantio e orientação de cultivo. Nesse contexto, duas culturas que merecem destaque em ambientes quentes e secos são palma forrageira e sorgo forrageiro, ambas apresentam elevada eficiência no uso dos recursos, com produtividade satisfatória, além da existência de trabalhos que evidenciam os benefícios na associação dessas culturas na dieta alimentar dos animais. Dessa forma, na presente revisão, objetivou-se analisar as melhorias produtivas e estruturais das culturas da palma e sorgo sob adoção de práticas de resiliência agrícola. Os achados desta revisão, podem servir como subsídios para o planejamento da produção de forragem, ao tempo em que sugerem que a adoção de práticas adequadas (i.e. irrigação, consorciação, orientação de cultivo e densidade) e suas combinações no sistema de produção permitem um melhor aproveitamento dos recursos naturais e, com isso, maiores acúmulos de biomassa, constituindo-se em fatores determinantes para o êxito na produção.Palavras-chave: configuração de cultivo, densidade e orientação de plantio, Opuntia stricta, Nopalea cochenillifera, Sorghum bicolor. Agricultural resilience in intercropped forage cactus-sorghum cultivation in a semi-arid environment: A review A B S T R A C TThe success of agribusiness in the livestock sector depends on the supply of fodder for animals, especially in semi-arid areas, where climatic characteristics and low food availability can hamper activity. Therefore, the use of agricultural practices that improve the agricultural resilience of crops and make it possible to offer fodder throughout the year for animals becomes essential. Among such practices, the following stand out: the use of species adapted to climatic conditions, choice of cultivation configuration, planting density and cultivation orientation. In this context, two crops that deserve to be highlighted in hot and dry environments are forage cactus and forage sorghum, both have high efficiency in the use of resources, with satisfactory productivity, in addition to the existence of studies that show the benefits in the association of these cultures in the diet animal feed. Thus, in this review, the objective was to analyze the productive and structural improvements of palm and sorghum crops under the adoption of agricultural resilience practices. The findings of this review may serve as inputs for the planning of forage production, while suggesting that the adoption of appropriate practices (i.e. irrigation, intercropping, cultivation and density guidance) and their combinations in the production system allow for a better use of natural resources and, with this, greater accumulations of biomass, constituting determining factors for success in production.Keywords: cultivation setting, density and orientation planting, Opuntia stricta, Nopalea cochenillifera, Sorghum bicolor.

“…Therefore, a convenient and efficient alternative is the use of Remote Sensing (RS) techniques, which indirectly allow the quality characterization of extensive water bodies for different periods, making it feasible to remotely analyze water quality characteristics ( Aman et al, 2020 ). More importantly, in-depth studies aimed at identifying and characterizing the environmental changes imposed by the reduction of human activity in the environment, followed by the assessment of the impacts generated, are essential for the development of public policies in the short and long term, in addition to raising population awareness ( Santos et al, 2020a ; Silva et al, 2020a , 2020b ; Buck et al, 2021 ). Moreover, the effective use of RS techniques and satellite image geoprocessing enables the expansion of environmental studies in an effective, reliable, practical, and fast way ( Silva et al, 2021a ).…”
