Book Description
“Groundbreaking in its call to reconsider our approach to the slow rhythm of time in the very concrete realms of environmental health and social justice.” —Wold Literature Today The violence wrought by climate change, toxic drift, deforestation, oil spills, and the environmental aftermath of war takes place gradually and often invisibly. Using the innovative concept of "slow violence" to describe these threats, Rob Nixon focuses on the inattention we have paid to the attritional lethality of many environmental crises, in contrast with the sensational, spectacle-driven messaging that impels public activism today. Slow violence, because it is so readily ignored by a hard-charging capitalism, exacerbates the vulnerability of ecosystems and of people who are poor, disempowered, and often involuntarily displaced, while fueling social conflicts that arise from desperation as life-sustaining conditions erode. In a book of extraordinary scope, Nixon examines a cluster of writer-activists affiliated with the environmentalism of the poor in the global South. By approaching environmental justice literature from this transnational perspective, he exposes the limitations of the national and local frames that dominate environmental writing. And by skillfully illuminating the strategies these writer-activists deploy to give dramatic visibility to environmental emergencies, Nixon invites his readers to engage with some of the most pressing challenges of our time.

Book Description
Conflict over cultural heritage has increasingly become a standard part of war. Today, systematic exploitation, manipulation, attacks, and destruction of cultural heritage by state and non-state actors form part of most violent conflicts across the world. Such acts are often intentional and based on well-planned strategies for inflicting harm on groups of people and communities. With this increasing awareness of the role cultural heritage plays in war, scholars and practitioners have progressed from seeing conflict-related destruction of cultural heritage as a cultural tragedy to understanding it as a vital national security issue. There is also a shift from the desire to protect cultural property for its own sake to viewing its protection as connected to broader agendas of peace and security. Concerns about cultural heritage have thus migrated beyond the cultural sphere to worries about the protection of civilians, the financing of terrorism, societal resilience, post-conflict reconciliation, hybrid warfare, and the geopolitics of territorial conflicts. This volume seeks to deepen public understanding of the evolving nexus between cultural heritage and security in the twenty-first century. Drawing on a variety of disciplines and perspectives, the chapters in this volume examine a complex set of relationships between the deliberate destruction and misuse of cultural heritage in times of conflict, on the one hand, and basic societal values, legal principles, and national security, on the other.
