“…So, there is still a gap in the literature for redoing this work with statistical methods, such as cluster analysis. Until now, studies involving a precipitation clustering process focused only on specific regions of the continent, such as the tropical SA [78], Bolivia [79], Argentina [80][81][82][83], Chile [84], Colombia [85], Ecuador [86], Brazil [87,88], and Brazilian sectors, such as the northeast [89][90][91][92][93][94], south and southeast [95][96][97], central-west [98], and the Amazonian portion [99]. In this scenario, the present study's relevance is justified not only for identifying homogeneous rainfall regions in SA considering a recent period (1993-2016) and an objective methodology but also by evaluating the skill of last generation climate predictions provided by ECMWF for South American continent.…”

South America is a vast continent characterized by diverse atmospheric phenomena and climate regimes. In this context, seasonal climate predictions are helpful for decision-making in several relevant socioeconomic segments in this territory, such as agriculture and energy generation. Thus, the present work evaluates the performance of ECMWF-SEAS5 in simulating the South American precipitation regimes by applying a non-hierarchical clustering technique. In addition, the study describes the main atmospheric systems that cause precipitation in each cluster and updates a previous work performed in South America in 2010. As a result, ECMWF-SEAS5 simulates (with good correspondence) the eight climate regimes identified in the analysis of precipitation from the Climate Prediction Center (CPC). Moreover, ECMWF-SEAS5 has a satisfactory ability in representing the rainfall regime in low and medium climate predictability regions, such as central and southern South America. ECMWF-SEAS5 has good performance in the climate characterization of South America and it gives us confidence in using its seasonal climate predictions throughout the continent.

“…As mudanças climáticas poderão influenciar de modo negativo a atividade agrícola no Brasil, causando perdas econômicas a curto, médio e longo prazo (Carlos;. Estudos sobre o efeito do aquecimento global têm detectado mudanças no padrão da precipitação pluvial e aumento da temperatura do ar, que associados, poderão modificar o comportamento da evapotranspiração (Lacerda et al, 2015;Jardim et al, 2021c). Como tal, as atividades agrícolas serão diretamente afetadas, devido a redução da água presente no solo, e consequente aumento no déficit hídrico para as plantas (Araújo Júnior et al, 2021b).…”

A palma forrageira (Nopalea e Opuntia) é uma cultura de fundamental importância para o Semiárido brasileiro (SAB), principalmente como fonte de alimento para os animais. Devido ao seu Metabolismo Ácido das Crassuláceas (MAC) e traços morfofisiológicos. Essa cactácea apresenta fácil adaptação à ambientes com altas temperaturas do ar e déficit hídrico, exibindo elevada eficiência no uso da água e produção satisfatória de biomassa, sobretudo em épocas de longa estiagem. Contudo, ainda é necessário o emprego de práticas de manejo que possam melhorar ainda mais as respostas da palma às condições ambientais dessa região. Nesta revisão, objetivou-se discorrer sobre a utilização do manejo de corte baseado na relação fonte-dreno (FonDren) e o uso de irrigação complementar no cultivo da palma forrageira, de modo a melhorar o aporte forrageiro da agricultura familiar no Semiárido brasileiro. O manejo FonDren consiste na retirada de cladódios que não estejam participando ativamente no processo de fotossíntese (i.e., com injúrias e/ou sombreados), de forma a possibilitar maior emissão de novos, com incremento no desenvolvimento e acúmulo de biomassa da cultura. Por sua vez, a irrigação complementar à chuva, melhora o aproveitamento dos recursos hídricos locais, favorecendo o aumento do uso da água pela palma. A utilização dessas práticas em conjunto, pode incrementar o rendimento dos clones de palma forrageira, e promover maior aporte forrageiro aos sistemas produtivos de agricultura familiar do Semiárido brasileiro.Palavras-chave: Intensidade de corte, Nopalea, Opuntia, relação fonte-dreno, semiárido Sustainable management techniques for the fodder supply of family agriculture in the brazilian semiarid: forage cactus, irrigation and fondren A B S T R A C T The forage cactus (Nopalea and Opuntia) is a crop of fundamental importance for the Brazilian Semiarid Region (BSR), mainly as a source of food for animals. Due to its Crassulaceous Acid Metabolism (CAM) and morphophysiological traits. This cactus is easily adapted to environments with high air temperatures and water deficit, showing high efficiency in the use of water and satisfactory production of biomass, especially in times of long drought. However, it is still necessary to use management practices that can further improve cactus responses to environmental conditions in that region. In this review, the objective was to discuss the use of cut management based on the source-drain ratio (FonDren) and the use of complementary irrigation in the cultivation of forage cactus, in order to improve the forage contribution of family agriculture in the Brazilian Semiarid. FonDren management consists of removing cladodes that are not actively participating in the photosynthesis process (i.e., with injuries and/or shading), in order to enable greater emission of new cladodes, with an increase in the development and accumulation of biomass in the culture. In turn, irrigation complementary to rainfall improves the use of local water resources, favoring the increased use of water by the forage cactus. The use of these practices together, can increase the yield of forage cactus clones, and promote greater forage input to the productive systems of family agriculture in the Brazilian Semiarid.Keywords: Cutting intensity, Nopalea, Opuntia, source-drain ratio, semiarid

“…Dentre as regiões mais afetadas, destacam-se as áridas e semiáridas, ocasionando conflitos sociais e econômicos por este recurso (Mbarki et al, 2018;Santos et al, 2020). No entanto, alguns fatores são preponderantes para o agravamento da falta de água, como o aumento da temperatura e baixa umidade relativa do ar, altas taxas evapotranspirativas e irregularidade das chuvas, ocasionadas principalmente, pelas mudanças climáticas a partir do aumento da emissão de gases do efeito estufa, assim como do avanço acelerado da população, que resulta em maior demanda por alimentos (Wang et al, 2020;Yang et al, 2020;Jardim et al, 2021d).…”

The low forage productivity in the Brazilian semi-arid is linked to water scarcity and climatic conditions, these abiotic disturbances affect the development of livestock and the local economy. Seeking to circumvent the situation, the use of forage species adapted to climatic conditions is of paramount importance, such as forage cactus, a crop rich in nutrients, much appreciated by animals, but lacking in fiber and protein, making it necessary to use other forage plants like sorghum, millet, pigeon pea and forage sunflower, both species have high levels of fiber and protein, and with this, they complement each other and enable the production of more balanced diets for herds. However, the higher yield of crops is observed with the implementation of resilient practices such as irrigation, adoption of mulch, intercropping, which promotes more sustainable systems with high forage potential. In this review, the objective was to evaluate the use of different agronomic practices to increase the productivity and sustainability of forage cactus crops and crops of regional appeal to the Brazilian semi-arid region. It is concluded that the sustainable intensification of agricultural crops, through complementary irrigation, mulch, intercropping with forage cactus, and plant species adapted to the Brazilian semi-arid region, can promote an increase in forage production without adverse effects on ecosystems.
