This paper assess the controversies and tensions being created by the target of ambitious hydropower development plans in the name of climate mitigating energy in the Upper Tista River Basin of Sikkim (India) which is a part of Eastern Himalayan region. However, in the face of climate change, hydropower projects have become a contested developmental paradigm in the Easter Himalayan region of Sikkim. The paper highlights potential issues and conflicts between climate mitigation approaches through hydropower projects and anti hydropower forces of local people. The paper critically examines pre and post hydropower development conflicts and cooperation along Upper Tista river basin. In fact, the region has witnessed that the Hydro Power Project have been undermining environmental and social security over the past years. The study also analyse the different roles of dam affected people, local politicians, NGOs and dam developers in advocating and protesting of the hydropower dam projects in the region. Using an environmental security framework the study critically analyse the environmental risks and impacts being aggravated by combined forces of climate change and hydropower development in upper Tista catchment of Sikkim Himalaya (India).

We have studied a massive U(1) gauge holographic model with pure gauge and mixed gauge-gravitational Chern-Simons terms. The full backreaction of the gauge field on the metric tensor has been considered in order to explore the vortical and energy transport sector. The background solution has been computed numerically. On this background, we have considered the fluctuation of the fields and evaluated the different correlators. We have found that all the correlators depend on the mass of the gauge field. Correlators such as the current-current one, 〈JxJx〉, which were completely absent in the massless case, in the presence of a finite gauge boson mass start picking up some finite value even at zero chemical potential. Similarly, the energy-current correlator, 〈T0xJx〉, which was also absent in the massless theory, has now a non-vanishing value but for finite values of the chemical potential. Our findings for the chiral vortical conductivity, σV, and the chiral magnetic/vortical conductivity of energy current, $$ {\sigma}_B^{\varepsilon }={\sigma}_V^{\varepsilon } $$ σ B ε = σ V ε , are completely new results. In addition to this, we have found that these anomalous transport coefficients depend linearly both on the pure Chern-Simon coupling, κ, and on the mixed gauge-gravity Chern-Simon coupling, λ. One of the results that we would like to highlight is that it’s not just κ that contributes to the σB but there is an additional contribution from λ as well unlike the previous studies.
