The present report focuses on one of the more vulnerable blocks of the Sundarbans in West Bengal, India -- namely Patharpratima -- as a representative block of the Sundarbans. To understand the root of the problem, the study takes a child health right approach and attempts to understand whether and to what extent the rights are protected, especially in climatically challenged areas such as the Sundarbans. In a nutshell, this report generates research evidence on the barriers to service delivery and access of health care services for children and endeavours to find out ways to make the system more effective in the Sundarbans.
