Foreword

The contemporary global landscape is increasingly shaped by the convergence of armed conflict, pandemic disruption, and climate change, forming a complex system of mutually reinforcing crises that defy traditional analytical boundaries. War-torn countries are at the center of overlapping crises that intensify existing fragility. Already weakened by prolonged violence, weak institutions, and economic decline, they face added strain from droughts, floods, and environmental degradation. These pressures are compounded by global dynamics, including the Middle East crisis, the Ukraine war, US–China rivalry, and international sanctions, which disrupt supply chains and limit access to essential goods. The COVID-19 pandemic further deepened these vulnerabilities by contracting economies and overwhelming fragile health systems. In such settings, crises compound rather than coexist, driving displacement, poverty, environmental damage, and broader instability beyond national borders.

The introductory chapter establishes a strong conceptual and empirical foundation by examining the global socioeconomic consequences of the convergence of the COVID-19 pandemic, ongoing cross-border and internal conflicts, and natural disasters. It shows how supply chain disruptions, inflation, energy crises, and labor market contractions have arisen from these interconnected shocks, while also highlighting their wide-ranging impacts on global health, food security, displacement, and economic stability.

The chapter on Mexico offers a nuanced view of a middle-income country facing intersecting crises while contending with profound security, governance, and corruption challenges driven by powerful drug cartels. Having experienced more foreign armed interventions than any other Latin American country, it continues to struggle with high homicide rates, widespread disappearances, and deep-rooted institutional collusion between criminal groups and authorities. Against this backdrop, the chapter examines how the country navigates pandemic recovery, global conflict-driven economic volatility, and climate change. It analyzes policy responses to unemployment, inequality, and energy transition, while highlighting the vulnerabilities of indigenous communities and environmental threats to sustainable development.

The analysis of Afghanistan—at the crossroads of Central Asia, South Asia, and the Middle East and long a strategic corridor shaped by repeated invasions, rivalries, and internal conflict—emphasizes compounded fragility. Decades of conflict and entrenched extremism have weakened governance and socioeconomic stability under a hardline, theocratic regime. As one of the world’s major sources of refugees, often cited as the second-largest after Syria or Palestine, it faces ongoing displacement. This chapter shows how COVID-19 and climate stressors, especially drought and water scarcity, have intensified crises across agriculture, health, education, and labor, worsening food insecurity, gender inequality, and maternal and child health, while exposing limited resilience alongside deep developmental setbacks.

The global fuel crisis and inflation shock triggered by the 2022 Ukraine war and the post–COVID-19 recovery, comparable in some respects to the 1970s oil shocks, pushed inflation in many economies above levels observed during the 2008 Great Recession. The Israel–Hamas war, beginning in October 2023, diverted global attention and resources from Ukraine, contributing to intensified attacks and a complex imbalance. As a result, Ukraine, now experiencing more than four years of sustained conflict, faces extensive environmental damage, including farmland contaminated by unexploded ordnance, a record wildfire in 2025, soil erosion, and impacts on nearly one-fifth of protected areas. The chapter on the crisis in Ukraine further examines broader socioeconomic and environmental consequences, including damage to infrastructure, agriculture, education, and healthcare, along with forced migration, fiscal strain, rising poverty and unemployment, biodiversity loss, and pollution from heavy metals and radioactive contaminants.

In Sudan, decades of conflict since 1956—marked by wars, coups, and chronic instability—have stalled development and driven a deep humanitarian crisis, now worsened by the 2023 civil war shaped by regional powers competing for influence, resources, and access to the Red Sea, leaving roughly one in four people displaced and two in five facing acute hunger, while the Sudan and Red Sea crises—linked to the Israel–Hamas conflicts—intersect through shared actors, maritime competition, and Horn of Africa security risks that also disrupt global shipping. The chapter on Sudan illustrates how political instability, economic fragility, climate vulnerability, and pandemic pressures compound impacts across agriculture, education, employment, and healthcare, while worsening food insecurity, external debt, displacement, violations of women’s rights, and child health, underlining the strain of overlapping shocks on fragile systems.

The case of Yemen illustrates a multifaceted humanitarian crisis driven by a decade of conflict involving Middle Eastern, global, and extremist actors, with exploited religious divisions turning a local dispute into a broader sectarian war that has extended into the Red Sea, where attacks in the Bab-el-Mandeb Strait disrupt maritime trade and generate global economic effects. The prolonged conflict has devastated infrastructure and institutions, leaving the population highly vulnerable to climate and pandemic shocks and limiting access to routine childhood immunizations and COVID-19 vaccination. About one in eight people are displaced, and nearly half are either living in poverty or facing crisis-level (IPC Phase 3+) food insecurity, making Yemen the world’s third most food-insecure context after Sudan and Gaza. The chapter further examines severe disruptions in agriculture, water, fuel, health, and education, alongside rising unemployment, gender inequality, worsening health outcomes, water scarcity, aid dependency, and widespread food insecurity, illustrating how such crises become entrenched and self-perpetuating.

The Syrian conflict lasted nearly 14 years, ending in late 2024 with the fall of the Iran-backed Bashar al-Assad regime, though instability, territorial disputes, shifting regional power dynamics, and reported airstrikes in southern Syria persisted; earlier drought and resource mismanagement (2006–2010) contributed to displacement and unrest, leaving the country ill-prepared for the pandemic, while the Israel–Hamas conflict further deepened the crisis, doubling food inflation within a year and sharply depreciating the currency in this import-dependent economy. By the end of the war, about one in three people were internally displaced, around 6 million became refugees, and roughly 90% of the population lived in poverty amid destroyed infrastructure, severe food insecurity, and widespread landmine contamination—striking for a country with a rich ancient heritage and a historic role as a crossroads of trade, culture, and power. The chapter on Syria shows how overlapping conflict, environmental shocks, and pandemic pressures drove breakdowns in agriculture, education, and healthcare, alongside inflation, displacement, and gender-based violence, resulting in lasting social fragmentation and heightened vulnerability among displaced and marginalized groups.

Taken together, these chapters reveal a consistent and troubling pattern: the interaction of conflict, climate change, and pandemic shocks generates complex, multi-layered crises that exceed the capacity of conventional policy responses. War intensifies environmental degradation and disrupts economic systems; climate stress fuels resource scarcity and displacement; and pandemics expose and amplify structural inequalities while weakening already fragile institutions. In war-affected regions, these dynamics spiral into deeply entrenched socioeconomic crises, multiplying hardship and constraining recovery pathways. Strengthening institutional capacity, fostering international cooperation, and leveraging innovation while remaining attentive to social and ethical dimensions will be essential. The insights presented here offer a critical foundation for advancing such efforts, pointing toward a more coherent and effective response to the cascading crises that define the present and will shape the future.
