The concept of 'sustainable development' has evolved significantly since its popularization in the 1987 Brundtland Report. Initially, it was framed primarily as an environmental concern, emphasizing the need to balance economic growth with ecological preservation. However, contemporary scholarship argues that sustainability is inherently multidimensional, encompassing social equity, economic viability, and environmental integrity. Recent studies highlight the role of technological innovation and policy integration in achieving these goals, yet they also caution against over-reliance on market-based solutions. Critics point out that without robust governance and community engagement, sustainability initiatives may exacerbate existing inequalities. Thus, the modern discourse advocates for a holistic approach that recognizes the interdependence of human well-being and planetary health, urging policymakers to adopt adaptive and participatory strategies.
