Climate change is having major impacts on weather patterns, seasons, and the climate in Mizoram. Rising levels of greenhouse gases like carbon dioxide, methane, and nitrous oxide in the atmosphere are trapping heat and warming the planet. This is disrupting agricultural production and increasing vulnerabilities. Some key impacts include rising temperatures damaging crops, changing rainfall patterns affecting harvests, and increasing pest and disease outbreaks which are reducing yields. To address these challenges, the document recommends strategies like using short duration crop varieties, improving water management through irrigation, conservation, and harvesting, adopting organic farming techniques, and providing farmers with weather and agricultural advisories. Diversifying livelihoods is also important given climate change threats across different sectors
