The factors lead to crop production decrease:
1. floods  2. droughts  3. extreme temperature

CROP PRODUCTION DECREASE 
>>>DESTABILIZE FOOD SYSTEMS
>>>THREATEN  GLOBAL FOOD SECURITY

SOLUTION:
policymakers need robust scientific information to develop effective disaster risk management and 
adaptation interventions( e.i.: infrastructure, technology, management, and insurance)

CONCLUSION:
The global warming and other related issues mainly decreased the global crop production. Extreme heat or cold, floods, and droughts are the essential factors. To face these problems, policymakers need more robust scientific information, researchers should  also offer more data sharing to the public for developing effective disaster risk management. The decline of global crop production also damaged the food systems and threaten food security, which are also some leading social issues that need improvement and adaptations.
