Sugarcane Production under Changing Climate: Effects of Environmental Vulnerabilities on Sugarcane Diseases, Insects and Weeds

Abstract

Sugarcane is an important crop for bioenergy and sugar, contributing to Gross Domestic Product (GDP) of Pakistan. Global warming and increasing greenhouse gas emission result in the increased intensity and frequency of extreme weather events. Temperature stress is a major environmental stress that limits the sugarcane growth, productivity and metabolism worldwide. Numerous biochemical reactions are involved in plant development, and these biochemical reactions are very sensitive to temperature stress. Now a day, temperature stress is a major concern for sugarcane production and approaches for high yield of sugarcane under temperature stress are important agriculture goals. Sugarcane plant adapts a number of acclimation and avoidance mechanism against different environmental stress. Plant survival under different stresses depends on ability to generate and transmit the signal and biochemical and physiological changes. In future, climate change is an important consequence for sugarcane production in the world because of its relative low adaptive capacity, poor forecasting system and high vulnerable to natural hazard. In this review we briefly describe climate change effects on sugarcane, sugar production in several countries especially in Pakistan, future challenges for sugar production under changing climatic scenario and propose strategies for mitigation negative impacts of climate change.

Qualitative Study on the Observations of Emissions, Transport, and the Influence of Climatic Factors from Sugarcane Burning: A South African Perspective

“…Sugarcane is highly sensitive to water deficit, which can lead to a reduction of the sugarcane productivity by up to 60% [ 65 ]. On the other hand, excess water amounts can also have an increase in weeds, diseases, and insect pest on the sugarcane crop [ 66 ] and, thus, affect productivity. Therefore, adequate amounts of water are required for a healthy yield of the sugarcane crops.…”

Socio-economic Determinants of Sugarcane-Soybean Intercropping among Smallholder Farmers in Awendo Sub-County, Kenya

“…Several studies have evaluated the impact of climate change on sugarcane production and other annual crops focusing on the agronomic aspects [33][34][35][36][37][38]. However, little has been done to assess farmers' socio-economic effects on Sugarcane-Soybean Intercropping.…”

Unlocking the inherent potential of plant genetic resources: food security and climate adaptation strategy in Fiji and the Pacific

“…The economic cost of cyclone damage to sugarcane farmers in Fiji was 20 million US$ in 1983 due to TC Oscar, and 21.7 million US$ due to TCs Eric and Nigel in 1985 (Rosegrant et al 2015 ). Both drought and waterlogging are detrimental for cane growth, and can reduce yield by up to 60% and 18–64% respectively, depending on the cultivars, duration of stress and plant growth stage (Zhao and Li 2015 ; Hussain et al 2018 ). Misra et al ( 2020 ) compared morphological losses in sugarcane subjected to drought versus waterlogging and found higher losses under water deficits.…”
