  • The waves' occasional splashing against the roof of a cave may enlarge the joints when compressed air is trapped inside.

Explanation: Established in 1994, the United Nations Convention to Combat Desertification (UNCCD) is the sole legally binding international agreement linking environment and development to sustainable land management. The Convention addresses specifically the arid, semiarid and dry sub-humid areas, known as the drylands, where some of the most vulnerable ecosystems and peoples can be found.
The Convention is committed to bottom-up / Decentralized approach, encouraging the participation of local people in combating the desertification. Hence, statement 3 is correct.
The secretariat helps in compiling information and reports, not in allocating finances and the south Asian region is not in focus. Hence, statement 2 is wrong
Educational Objective: To know about UNCCD.
