Explanation:

• Statements 1 and 3 are correct. The Krishi-DSS provides real-time data-driven insights on weather patterns, soil conditions, crop health, and more, which are essential for crop management, enhancing productivity, and issuing disaster warnings like pest attacks and heavy rain. The Krishi-DSS uses crop mapping and monitoring to analyze cropping patterns, which helps in understanding crop rotation practices and promotes sustainable agriculture by encouraging the cultivation of diverse crops. It has been developed using technology similar to the flagship Gati Shakti initiative to deliver early warnings about potential disasters such as pest attacks and extreme weather events. 

• Statement 2 is incorrect. Krishi-DSS system primarily uses geo-spatial and satellite technology to provide its services. The platform can be used to monitor drought conditions, providing valuable information for managing water resources and planning agricultural activities. It offers information on weather patterns, soil conditions, crop health, and crop acreage.

Hence option 3rd is correct.
