Drought Hotspots Around the World 2023-2025 Syllabus:Ecology The UN Convention to Combat Desertification (UNCCD) and the U.S. National Drought Mitigation Centre have jointly released a global report highlighting the intensification of drought zones between 2023 and 2025. These events have been termed as “slow-moving catastrophes” due to their broad and systemic impacts.   Global Trends and Key Hotspots: Africa’s Food Crisis:Over 90 million people in Eastern and Southern Africa are facing acute food insecurity. Zimbabwe has suffered maize crop losses of more than 70 percent. Zambia’s Energy Collapse:The Zambezi River’s flow has fallen to just 20 percent of its long-term average, resulting in up to 21-hour daily power outages and disruption of essential public services. Spain’s Agricultural Shock:Two consecutive years of drought have halved Spain’s olive oil production, significantly contributing to price surges across Europe. Panama Canal Slowdown:Drought conditions reduced the number of ship transits through the Panama Canal from 38 to 24 per day, disrupting global trade and impacting food supply chains. Amazon River Crisis:Record-low water levels in the Amazon have isolated riverine communities, killed over 200 river dolphins, and exposed serious ecological vulnerabilities. Humanitarian Fallout:In Ethiopia and Zimbabwe, drought-induced poverty has led to a doubling of child marriages and a spike in school dropout rates. Wildlife Devastation:Over 100 elephants have died in Zimbabwe, while extreme heat and water shortages have caused mass aquatic deaths in the Amazon basin.   India’s Drought Vulnerability: Monsoon Irregularities:Intra-seasonal rainfall variability is increasing, affecting water availability and crop productivity. Crop and Price Instability:Drought-related declines in rice and sugar production across Asia have led to rising food inflation in India. Hydrological Stress:River basins such as the Godavari and Krishna are facing frequent droughts due to over-extraction of water and poor watershed management. Socioeconomic Impact:States like Maharashtra, Karnataka, and Rajasthan are experiencing increasing farmer distress, rural-urban migration, and economic strain. Primary Drivers of Worsening Droughts: Climate Change: Rising global temperatures are accelerating evapotranspiration, leading to prolonged dry spells. El Niño Effect: The 2023–2024 El Niño event has intensified drought in key agricultural regions. Unsustainable Resource Use: Excessive groundwater extraction, deforestation, and mismanaged irrigation are worsening water scarcity. Weak Governance: The lack of effective early warning systems and adaptive water policies has amplified drought vulnerability.   Consequences of Drought Hotspots: Food Insecurity: In Zambia, maize prices have doubled, while global staple crop yields are under severe threat. Energy Shortages: Hydropower shortages have disrupted electricity supply in Zambia and Türkiye, impacting hospitals, homes, and industries. Biodiversity Collapse: Drought conditions have led to mass wildlife deaths and ecosystem degradation. Human Displacement: Somalia and parts of the Amazon basin are experiencing displacement and rising rates of acute child malnutrition. Policy Recommendations: Early Warning and Impact Monitoring Systems: Implement real-time data tracking to improve early response mechanisms. Nature-Based Solutions: Restore degraded ecosystems, encourage cultivation of drought-resilient crops, and reforest critical watersheds. Gender-Sensitive Adaptation Strategies: Address the specific vulnerabilities of women and girls, including risks of child marriage and educational disruption. Regional and Transboundary Cooperation: Strengthen diplomatic partnerships for shared river basin management and trade resilience. Infrastructure Investment: Promote sustainable agriculture, off-grid renewable energy, and water harvesting technologies. Climate Finance: Mobilize global funding through mechanisms like the International Drought Resilience Alliance (IDRA) to support vulnerable regions.   Conclusion: Droughts are increasingly becoming prolonged, systemic emergencies that jeopardize ecosystems, economies, and human wellbeing. The intensification of drought hotspots from 2023 to 2025 signals a critical turning point. Without immediate, inclusive, and coordinated global action, these crises could become the norm in an era of climate uncertainty. Building drought resilience must be prioritized in global adaptation and development strategies. Consider the following statements regarding the recent Drought Hotspots 2023–2025 report by the UNCCD: The report identifies drought as a rapid-onset disaster with short-term climatic impacts. The Zambezi River’s reduced flow led to a hydropower surplus in Zambia, allowing energy exports. The Amazon River recorded its lowest water levels on record, affecting both biodiversity and transportation. Which of the above statements is/are correct?A. 1 onlyB. 3 onlyC. 1 and 2 onlyD. 2 and 3 only  Answer:BExplanation: Statement 1 is incorrect as the report refers to droughts as “slow-moving catastrophes”. Statement 2 is incorrect—Zambia faced 21-hour blackouts, not a surplus. Statement 3 is correct. Embracing Genetic Innovation for India’s Agricultural Future Syllabus:Geography   Context: India is under increasing international pressure to liberalise its agricultural biotechnology market, even as its domestic innovation ecosystem for genetically modified (GM) crops remains tightly constrained. Despite global advancements, India has officially approved only Bt cotton, while other GM crops like Bt brinjal and GM mustard remain entangled in regulatory hurdles.   Current Landscape of Indian Agriculture and GM Technology Declining Productivity: Cotton yield has fallen from 566 kg/ha (2013–14) to 436 kg/ha (2023–24), placing India far behind global leaders like China and Brazil (1,800–1,900 kg/ha). Import Dependency: Once a net cotton exporter, India now imports over $0.4 billion worth of cotton (2024–25). Biotech Stagnation: While the global GM crop acreage has crossed 200 million hectares across 76 countries, India continues to cultivate only Bt cotton Other GM variants remain in limbo. Yield Gap and Technology Lag: India’s output suffers due to the lack of approved GM variants for major crops like soy, corn, mustard, and brinjal.   Governmental Interventions & Initiatives Bt Cotton (2002): Its approval led to a 193% surge in production over a decade. Cotton Seed Price Control Order (SPCO), 2015: Imposed trait fee caps, deterring further biotech investments. GM Mustard (2022): Received environmental clearance from the GEAC, but commercial rollout remains stalled. Jai Anusandhan Initiative: Launched a ₹1 lakh crore Research-Development-Innovation (RDI) fund to build a robust agri-biotech ecosystem. Technology Transfer Mandates (2016): Compulsory licensing and capped royalties discouraged private innovation and FDI.   Challenges in Adoption of GM Crops Regulatory Bottlenecks: Bt brinjal has faced a moratorium since 2009, despite scientific clearance. Illegal Cultivation: HT-Bt cotton, although unapproved, is grown in five major states—covering nearly 25% of cotton acreage. Pest Resistance: Bt cotton now faces rising attacks from pink bollworms and whiteflies due to overuse
