(2018) provides insights into how precision agriculture techniques can significantly improve the sustainability of sugarcane production by reducing inputs and maximizing outputs. 4.2 Bioenergy and bioproducts The development of biorefineries to process sugarcane byproducts into bioenergy and other valuable bioproducts is a key innovation that enhances the sustainability of the sugarcane industry. Byproducts such as bagasse and vinasse, which are traditionally considered waste materials, can be converted into bioelectricity, bioethanol, bioplastics, and biofertilizers. This not only adds value to the sugarcane industry but also reduces environmental pollution by minimizing waste disposal issues. Biorefineries integrate various technological processes to extract maximum value from sugarcane byproducts. For example, the conversion of bagasse into bioethanol involves enzymatic hydrolysis followed by fermentation, turning what would be waste into a valuable fuel that can replace gasoline. Similarly, vinasse can be used to produce biogas or as a nutrient-rich biofertilizer, enhancing soil fertility and reducing the need for synthetic fertilizers (Talakayala et al., 2020). The research by Kumar et al. (2018) examines the enhancement of sugarcane fertilization for energy purposes in hot climates, highlighting how technological advances in the treatment and utilization of byproducts can lead to significant environmental and economic benefits. 4.3 Genetic improvement Genetic improvement through traditional breeding and modern genetic engineering is crucial for developing sugarcane varieties that are more resistant to pests, diseases, and environmental stresses such as drought and salinity. These improved varieties can significantly enhance the sustainability and efficiency of sugarcane production by reducing the need for chemical inputs like pesticides and irrigation water, and by improving crop resilience and yield stability under varying climatic conditions. Breeding programs focus on identifying and incorporating genetic traits that confer resistance to biotic and abiotic stresses, while genetic engineering allows for the precise insertion of genes into the sugarcane genome. This can expedite the development of improved varieties that might take decades to develop through traditional breeding methods. The work by Li and Solomon (2015) demonstrates how genetic improvements, particularly in developing disease-resistant and stress-tolerant sugarcane varieties, can lead to more sustainable production practices by reducing crop losses and minimizing the environmental impact of cultivation. 5 Case Studies and Real-World Applications 5.1 Brazil: implementation of green harvesting and bioenergy production Brazil, as one of the world’s leading producers of sugarcane, has been at the forefront of adopting sustainable agricultural practices to mitigate environmental impacts and enhance productivity. The researches provided highlight significant trends and shifts in Brazil’s sugarcane industry, showcasing the successful implementation of green harvesting techniques and the integration of precision agriculture. Green harvesting, also known as mechanized harvesting without pre-harvest burning, has been a pivotal shift in Brazil’s sugarcane industry. Bordonal et al. (2018) shows a significant shift in sugarcane harvesting methods in the central and southern regions of Brazil, gradually transitioning from traditional manual incineration harvesting to green mechanized harvesting. This change not only enhances the sustainability of agricultural production, but also has a positive impact on environmental protection and efficient resource utilization. With the widespread adoption of mechanized harvesting technology, the sugarcane industry is moving towards a more environmentally friendly and efficient direction.
