UPSC CSE 2023 (Prelims) CSAT Official Paper (28-May-2023)

Climate change presents a grave threat to food security, particularly in tropical countries already vulnerable to environmental shifts. Rising temperatures and altered rainfall patterns disrupt traditional agricultural calendars, leading to unpredictable growing seasons and reduced crop yields for staples like rice, maize, and wheat. Extreme weather events, such as prolonged droughts, intense floods, and destructive cyclones, are becoming more frequent and severe, wiping out crops, damaging infrastructure, and displacing farming communities.

Beyond direct crop impacts, higher temperatures accelerate pest infestations and spread crop diseases, further diminishing harvests. Changes in oceanic temperatures and acidification threaten marine ecosystems, impacting fishing communities reliant on these resources for food and livelihoods. Smallholder farmers, often lacking resources for adaptation, are disproportionately affected, leading to increased poverty, malnutrition, and forced migration. For these nations, climate change isn't a distant threat; it's an immediate crisis unfolding on their farms and in their homes.
