    Groundwater vulnerability assessment is an important task in water resources and land management. The most sophisticated among the vulnerability assessment techniques is the GIS-based DRASTIC model. However, despite its popularity, it is marred with excessive subjectivity glitches; little research has been conducted to address the shortcomings associated with this method. This study investigates various issues regarding the application of the GIS-based DRASTIC model through a critical review of relevant literatures.

    Citizenship is an abstract concept and therefore great care must be taken in explaining what it means in practice and what can effectively be done in the context of development interventions and policy. Development projects which enhance the ability of marginalised groups to access and influence decision-making bodies are implicitly if not explicitly working with concepts of citizenship. Citizenship is about concrete institutions, policy and structures and the ways in which people can shape them using ideas of rights and participation.
