“…For soybean and maize crops, rising temperatures might alter the developmental rates, the phenological and physiological responses (Streck et al ., 2012; Martins et al ., 2019; Fatima et al ., 2020), as well as disrupt crop growth and development, and modify the areas currently suitable for both crops (Assad et al ., 2016;Ramirez‐Cabral et al ., 2017; Zilli et al ., 2020). In addition, for both crops a shorter growing season is projected, that is, an anticipation of phenological stages, mainly in southern Brazil (Streck et al ., 2012; Minuzzi et al ., 2017), Argentina, and Uruguay (Fatima et al ., 2020), and a longer growing season, that is, an extension of phenological stages in parts of the southeast and northeast Brazil (Martins et al ., 2019). Both situations may lead to significant changes in‐field management practices, such as pests and diseases occurrence and rotation schedule, which can be exacerbated by an additional local heating of 0.5°C (Streck et al ., 2012; Assad et al ., 2016; Cera et al ., 2017; Minuzzi et al ., 2017).…”

In principle, the anticipation of the phenological stages can be beneficial, allowing more than one soybean and maize cropping per year (Streck et al, 2012;Ramirez-Cabral et al, 2017;Martins et al, 2019).…”

Even if the thresholds set out in the Paris Agreement are reached, several impacts on the climate system are still inevitable, generating new vulnerabilities and amplifying those that already exist. In this sense, the objective of this work was to analyse the impact of a global warming of 1.5 and 2°C in the regional climatological patterns of the near‐surface air temperature and precipitation over South America, locating the most affected regions and briefly discussing the possible impacts to be faced on biodiversity and agriculture. The simulations and projections of 26 General Circulation Models (GCMs) from the Coupled Model Intercomparison Project Phase 5 were used, forced in four different Representative Concentration Pathways (RCPs) scenarios. Projections for 1.5 or 2°C global warming indicate a local increase even higher, of at least +0.5°C, in almost the entire South American continent. Regarding precipitation, a similar pattern was also found between the two thresholds of global warming. GCMs project an increase of about 100 mm year−1 in the southern region of Brazil and in the northern portion of the Brazilian Northeast, in northern Argentina, Uruguay, and parts of Peru, Ecuador, Colombia and Venezuela; while the areas between the south of Chile and Argentina and the extreme north of South America show reductions of up to 150 mm year−1. In addition, both the temperature and precipitation patterns were practically similar between the four analysed RCPs scenarios. The results presented in this study indicate that even if the Paris Agreement is very successful, South America will still suffer several impacts and will need to take effective adaptation measures in the short term. This may have pervasive implications for the biodiversity and genetic resource base of the subcontinent, as well as may impair agricultural productivity or incur into considerable adaptation costs for the sector.

“…Levando-se em conta o cenário de médio prazo, um agricultor que está em Santo Antônio de Pádua precisará irrigar 4,8 mm a mais do que um agricultor que está em Itaperuna. Minuzzi et al (2017) analisaram o desempenho agronômico da soja cultivada no sul do Brasil para tanto utilizaram dados climáticos de três municípios localizados nas principais regiões produtoras de soja e simularam a duração do ciclo, produtividade, eficiência do uso da água na produtividade da água evapotranspirada (EUA), requerimento de irrigação líquida e o índice de colheita ajustado em diferentes cenários climáticos, baseados nas projeções em curto prazo (2016-2035) e médio prazo (2046-2065) do cenário RCP4.5 do IPCC. Esses autores observaram que a duração do ciclo da soja tende a diminuir quanto mais frio for a localidade e, também que a produtividade e a EUA devem aumentar, mesmo que não haja requerimento de irrigação nos cenários climáticos futuros.…”

Este estudo teve o objetivo de determinar o requerimento de água provindo de irrigação para diferentes variedades de laranjeira e cenários climáticos nas mesorregiões Norte e Noroeste do estado do Rio de Janeiro. Dados climáticos dos municípios de Campos, Itaperuna e Santo Antônio de Pádua foram utilizados no software Cropwat 8.0 para simular o requerimento de água para irrigação por dois métodos, para o clima atual (1981 a 2010) e nos cenários climáticos baseados nas projeções de curto (2016-2035) e médio (2046-2065) prazos dos cenários RCP4.5 e RCP8.5 do Painel Intergovernamental sobre Mudança Climática (IPCC, sigla em inglês). Os resultados mostraram tendências de aumento no requerimento de água para irrigação nos três grupos de variedades de laranjeira, sendo que os maiores valores ocorreram no grupo da variedade ‘tardia’ e no município de Santo Antônio de Pádua, tanto a curto como de médio prazos. Porém, considerando os inexpressivos aumentos de irrigação em relação a duração dos ciclos das três variedades de laranjeira, o clima projetado para a região de estudo ainda será suficiente para satisfazer as necessidades de água para os três grupos de variedades de laranjeira.

“…This is possible because most atmospheric CO 2 emission scenarios demonstrate the continuity and increase in emissions in the future, and the soybean crop will benefit from this. This trend is more evident when analyzing the studies [59,62,63,68] in which time frames are compared within the same studies, assuming the same research variables. This fact demonstrates an increasing soybean yield in Brazil since future climate changes must increase over the years.…”

Brazil is one of the main producing and exporting countries of corn and soybean and a continental country with climatic diversity that allows the cultivation of these crops in various agricultural systems. Double cropping is a widely adopted system throughout the national territory, where it is possible to cultivate soybeans at the beginning of the growing season, followed by corn in succession, in the same growing season. The present study aims to systematize the scientific knowledge about the impacts of future climate change scenarios on yield and on the double-cropping system of soybean + corn in Brazil. Systematic review procedures were adopted. The soybean yield is projected to increase in all regions of Brazil under all climate scenarios. Corn yields under future climate scenarios are projected to decline, with the subtropical climate region being less affected than the northern regions. The double-cropping systems of soybean + corn tend to present increasing climate risks in tropical climate regions. Climate change scenarios point to a delay in the start of the rainy season that will delay the sowing of soybeans, consequently delaying the sowing of corn in succession, resulting in fewer rainy days to complete its cycle.
