A challenge to food security in Tamil Nadu is:

Climate change impacts on agriculture
Increasing population
Diversion of agricultural land
All of the above

All of the above are challenges to food security in Tamil Nadu.

Climate change is having a significant impact on agriculture in Tamil Nadu. The state is experiencing more extreme weather events, such as droughts and floods, which are disrupting crop production. In addition, rising temperatures are making it more difficult for farmers to grow certain crops.

The increasing population of Tamil Nadu is also putting a strain on the state’s food supply. The population is growing at a rate of 1.5% per year, which means that the demand for food is increasing. This is making it more difficult for the state to produce enough food to meet the needs of its people.

The diversion of agricultural land for other purposes, such as development, is also a challenge to food security in Tamil Nadu. This is reducing the amount of land that is available for growing crops. In addition, the conversion of agricultural land to other uses can lead to soil erosion and pollution, which can further damage the state’s agricultural sector.

These challenges are making it more difficult for Tamil Nadu to achieve food security. The state government is taking steps to address these challenges, but it is a complex and difficult issue.
