Resource nexus perspectives in the Blue Economy of India: The case of sand mining in Kerala.

Since the 2000 s the demand for sand has proliferated at the coastal-land interface to fill up the increasing demand straining Blue Economy (BE) activities and provision of water-energy-food resources. Recent studies have revealed that increased sand mining in both coastal and freshwater zones has continued to impact livelihood-ecological systems threatening the provision of livelihood goods and services. These impacts are exacerbated by a lack of comprehensive frameworks to regulate sand mining and trade; creating the need to develop micro and macro-frameworks and guidelines for sustainable sand mining. This paper uses a non-systematic literature review approach to build on this gap to develop an understanding of the resource nexus perspectives and trade-offs due to sand mining. The paper proposes a novel framework based on the Ecosystem Service Assessment advanced from the review of the literature to guide risk assessments toward more sustainable sand mining. In order to add evidence, the paper analyses in-depth the state of Kerala - one of India's coastal states that has experienced unprecedented rates of sand mining since the 1990 s especially along the Chavara coast albeit with less research on the intersectionality of mining on the resource nexus. Both the framework and our case study highlight how sand mining stresses local ecosystems and livelihoods thus increasing vulnerability to both human and environmental impacts. The paper brings to the fore seven (7) key steps that local institutions can use to guide sustainable sand mining and build integrated governance systems that promote interaction among natural capitals in a given area and livelihood considerations. The article further documents that the use of coherent guidelines and the framework can help in amalgamating the various actors in a given system that can guide local participation in local resource management and the development of cooperative agreements for the sustainable utilization of resources among coastal communities. This could further help understand the resource nexus from the perspective of the synergies and trade-offs in the BE. • The Blue Economy and Resource Nexus offer new pathways for sustainable livelihoods. • But, the proliferation of sand mining is increasing trade-offs thus livelihood and ecosystem vulnerability. • A lack of a comprehensive sand mining governance framework increases such vulnerability. • The developed novel framework based on Ecosystem Service Assessment can help reverse these externalities and trade-offs. • Our framework integrated new insights on sand mining governance that could be leveraged at all levels [ABSTRACT FROM AUTHOR]
