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, focusing on the preservation of natural resources for future generations. However, contemporary scholarship argues that sustainability is a tripartite paradigm, encompassing not only ecological integrity but also economic viability and social equity. This holistic view posits that environmental degradation is often intertwined with issues of poverty and inequality, as marginalized communities disproportionately bear the burden of pollution and resource depletion. Consequently, effective sustainability policies must address these systemic social and economic factors, rather than merely implementing technological fixes. This shift in perspective has profound implications for international development agendas, urging a move away from purely growth-oriented models towards more inclusive and resilient strategies that prioritize human well-being and planetary health in tandem.
