- The UNCCD is a global convention that addresses desertification, land degradation, and drought (DLDD). It promotes integrated approaches to land management. - Statement 1 is correct: The convention aims to promote effective action through innovative national programmes and supportive international partnerships. - Statement 3 is correct: The UNCCD emphasizes a bottom-up approach, recognizing the crucial role of local communities and their participation in combating desertification. - Statement 2 is incorrect: While desertification affects South Asia and North Africa, the UNCCD's focus is global, particularly on affected areas in Africa, Asia, Latin America and the Caribbean, Northern Mediterranean, and Central and Eastern Europe. The Secretariat facilitates resource mobilization but does not have a specific mandate to allocate a major portion solely to South Asia and North Africa.
