This chapter explores the profound impact of the recent war (October 2023–January 2025) on Gaza on Sustainable Development Goal 12 (SDG 12), which focuses on ensuring sustainable consumption and production patterns. This Israeli genocidal war has severely disrupted consumption and production systems in Gaza, leading to unsustainable practices that hinder long-term development and environmental stability. The chapter delves into the extensive damage inflicted by the war on key infrastructure, including manufacturing facilities, supply chains, and waste management systems. The destruction has led to reliance on inefficient and unsustainable practices, exacerbating resource scarcity and environmental degradation. Key issues addressed include the collapse of local industries, increased waste from damaged goods and buildings, and challenges in managing hazardous materials. Social and economic implications are also discussed, such as increased unemployment and poverty, which drive unsustainable consumption patterns. This chapter illustrates how the war has reversed progress toward achieving SDG 12 in Gaza and highlights the need for collaborative efforts by local and international organizations to mitigate these impacts. Recommendations are provided for rebuilding systems in Gaza to promote sustainable production and consumption. This comprehensive examination aims to provide a deeper understanding of the critical challenges faced by the population of Gaza in achieving sustainable consumption and production, offering insights into the urgent actions needed to address these issues and promote long-term environmental and economic stability.
