Cross-disciplinary refers to the integration of knowledge and methods from different fields of study to address complex problems or create new insights. This approach encourages collaboration among experts from various disciplines, such as science, art, and technology, allowing for innovative solutions that might not emerge within a single field. For example, in the field of environmental science, professionals might work alongside engineers and sociologists to develop sustainable practices that consider both technical feasibility and social impact. By combining perspectives, cross-disciplinary efforts can lead to more comprehensive understanding and effective strategies in tackling real-world challenges.
