With reference to a conservation organization called 'Wetlands International', which of the following statements is/are correct? 1. It is an intergovernmental organization formed by the countries which are signatories to Ramsar Convention. 2. It works at the field level to develop and mobilize knowledge, and use the practical experience to advocate for better policies. Select the correct answer using the code given below.

Let's analyze the statements about 'Wetlands International': 1. It is an intergovernmental organization formed by the countries which are signatories to Ramsar Convention: This statement is incorrect. Wetlands International is a global non-profit organization (an international NGO) dedicated to the conservation and restoration of wetlands. It is not an intergovernmental body formed by the signatories to the Ramsar Convention. While it works closely with the Ramsar Convention and its contracting parties, it is distinct from it. 2. It works at the field level to develop and mobilize knowledge, and use the practical experience to advocate for better policies: This statement is correct. Wetlands International operates through a network of offices worldwide, conducting field projects, generating scientific knowledge about wetlands, and using this expertise to influence policy-making at local, national, and international levels to promote wetland conservation. Therefore, only statement 2 is correct.
