Future climate change projects positive impacts on sugarcane productivity in southern China

Climate Change Impacts on Sugarcane Production in Thailand

“…Therefore, an increase in rainfall intensity still improved sugarcane yield. Other studies reached a similar conclusion [24,28].…”

“…Moreover, Silva et al [26] found that rainfall was positively correlated with sugarcane production, whereas the temperature negatively influenced production in municipalities within Paraiba, Brazil. They also found that the mesoregion of Mata Paraibana has a higher probability of producing sugarcane than other mesoregions.The positive impact of climate change on sugarcane yield was also found in Mexico [27] and southern China [28]. In Mexico, developed the Agricultural Land Management Alternatives model and revealed the positive impacts of future climate change on sugarcane yields with increases of 1%-13% under the A2 scenario from the baseline.…”

“…In Mexico, developed the Agricultural Land Management Alternatives model and revealed the positive impacts of future climate change on sugarcane yields with increases of 1%-13% under the A2 scenario from the baseline. In southern China, Ruan et al [28] used the Agricultural Production Systems Simulator (APSIM)-Sugarcane model and found that the largest percentage change in sugarcane yields occurred at high latitude locations (e.g., Hezhou), with increased mean values of 44.2% and 23.5% for Representative Concentration Pathway (RCP)4.5 and RCP8.5 in the 2060s, respectively. On the other hand, in Africa, Adhikari, Nejadhashemi, and Woznicki [29] reviewed studies projecting the climate change impacts on sugarcane production and revealed that sugarcane will be resilient to temperature rise, but it will be vulnerable to rainfall variability.…”

Condição hidráulica determinante à ocorrência de estresse hídrico na cultura da cana-de-açúcar

“…A utilização de modelos de simulação de culturas possibilita a individualização da influência de fatores ambientais e a determinação de parâmetros que governam a simulação de processos físicos e fisiológicos que compõem o crescimento e o desenvolvimento das plantas. No tocante à pesquisa científica, os modelos de simulação têm sido amplamente empregados para a comparação de manejos nutricionais, análise dos efeitos do déficit hídrico no rendimento das culturas, planejamento do uso da água, avaliação do efeito de alterações climáticas na produtividade das culturas, entre outras aplicações, tanto no Brasil, como no exterior (SCARPARE, 2011;SINGELS, 2018;RUAN et al;HU et al, 2019). Portanto, os modelos constituem uma ferramenta útil e indispensável, na medida em que o desempenho das culturas depende de interações complexas entre aspectos edáficos e condições meteorológicas, bem como de decisões sobre o seu manejo.…”
