Darien Gap
Why in news?
Panama reported a sharp decline in irregular migration through the Darien Gap in early 2025, following stricter border controls, regional cooperation, and US policy changes reducing incentives for northward migration.
About Darien Gap:

- Location:
- The Darien Gap is a dense and treacherous jungle between north-western Colombia and southern Panama.
- It forms a 160-km break in the Pan-American Highway, the only overland gap stretching from Alaska to Argentina.
- The region has thick rainforests, swamps, and rugged mountains, making it one of the most challenging terrains for human movement.
- Role in Illegal Immigration:
- Despite its difficult geography, the Darien Gap has become a major migration corridor for thousands of irregular migrants, primarily from Venezuela, Haiti, Cuba, and Africa, seeking to reach the United States and Canada.
- Migrants, often with the help of smugglers, undertake the dangerous journey through the jungle to bypass legal border crossings.
- The region’s inaccessibility makes it difficult for law enforcement to control illegal crossings, leading to unregulated migration, human trafficking, and organised crime.
- Humanitarian Crisis
- The Darien Gap is notorious for its harsh conditions and human suffering. Migrants endure severe hunger, dehydration, diseases, and violence from criminal gangs who exploit them for money, often through robbery, extortion, or sexual violence.
- Many perished due to exposure, drowning, or lack of medical assistance, while those who survive suffer long-term physical and psychological trauma. The crisis has overwhelmed humanitarian organisations and strained Panama’s resources in providing aid.
- Ecological Concerns
- Illegal migration and human trafficking routes have caused deforestation, habitat destruction, and pollution in the Darien rainforest.
- Increased foot traffic has disturbed fragile ecosystems, threatened native species, and accelerated environmental degradation.
- Conservationists warn that continued human encroachment could irreversibly damage one of the world's most biodiverse regions, affecting local wildlife and indigenous communities.
Donbas region
Why in news?
The Founding Chief Prosecutor for the UN Special Court for Sierra Leone advocates for establishing a Multinational Force and Observers for the Donbas Region (MFO-DR), composed of non-NATO nations like China, India, and Brazil, to mediate and ensure stability in the conflict-ridden Donbas region, fostering peace between Russia and Ukraine.
About Donbas region:

- Location:
- The Donbas region is located in eastern Ukraine, bordering Russia, and consists of two key oblasts (administrative divisions in the former Soviet Union region): Donetsk and Luhansk.
- It is an industrial heartland rich in coal, steel, and manufacturing, making it economically significant.
- The region's proximity to Russia and its historical ties to Soviet-era industries and Russian-speaking communities have made it a focal point of geopolitical tensions.
- Origin of Conflict:
- The conflict in Donbas traces back to 2014, following Russia’s annexation of Crimea.
- Pro-Russian separatists, backed by Moscow, declared independence in Donetsk and Luhansk, leading to clashes with Ukrainian forces.
- The war escalated into a prolonged armed insurgency, with Russia providing military, financial, and logistical support to separatists while Ukraine sought Western aid to reclaim sovereignty.
- In 2022, Russia launched a full-scale invasion of Ukraine, intensifying the battle for Donbas. The region became a key war zone, with cities like Mariupol, Severodonetsk, and Bakhmut witnessing some of the deadliest battles.
- Russia’s goal has been to secure complete control over Donbas, claiming to protect Russian-speaking populations, while Ukraine has resisted, viewing the conflict as a fight for national sovereignty.
- Other Key Regions in the War
Beyond Donbas, several other regions have played a critical role in the war:
- Crimea: Annexed by Russia in 2014, Crimea remains central to Moscow’s military strategy, serving as a base for naval operations in the Black Sea.
- Zaporizhzhia: Home to Europe’s largest nuclear power plant, Zaporizhzhia has been a contested battleground, raising fears of a nuclear catastrophe.
- Kherson: One of the first major cities captured by Russia in 2022, Kherson saw Ukrainian counteroffensives reclaiming lost territory.
- Kharkiv: Ukraine’s second-largest city, Kharkiv has faced relentless missile strikes, serving as a strategic front against Russian advances.
