TanDEM-X SAR mission was launched in June, 2010 with an aim to generate high resolution global DEMs of HRTI-3 specification. Considering this, it is very important to evaluate the accuracy of the DEM generated using TanDEM-X InSAR data over the rugged terrains of Indian Himalayas. This paper presents the results of an evaluation study of the DEMs generated through interferometric technique using TanDEM-X data over two Indian Himalayan glaciers viz. Hamtah and Gangotri.

Hamtah and Chhota Shigri are two nearby, well monitored glaciers of western Himalaya, lying in the same climatic zone and driven by the same climatic conditions. In this study, topographical characteristics of both the glacier have been explored to understand the role of topography in controlling the glacier response.

The cryosphere constitutes an important subset of the hydrosphere. The Himalayan cryosphere is a significant contributor to the hydrological budget of a large river system such as the Ganges. Basic data on the cryosphere in the Himalaya is inadequate and also has large uncertainties. The data on glacial melt component in the Himalayan rivers of India also shows high variability.

There was little improvement in EU Member States’ 2050 climate plans between 2015 and 2017, this new analysis from WWF shows. This makes the proposed Regulation on the Governance of the Energy Union, currently under discussion, critical to ensuring EU Member States produce effective long-term emissions reduction strategies.

Reviews of index-based agricultural insurance initiatives have identified several success factors that are relevant to the situation in Nigeria. First, successful initiatives have been designed to unlock particular opportunities for farmers that were previously constrained by particular risks.
