Siri Jodha Singh Khalsa: An Earthzine Personal Profile

Siri Jodha Singh Khalsa

The business of standards within the developing GEOSS community requires the commitment, expertise, and networking capabilities of a host of individuals. Foremost among these is Siri Jodha Singh Khalsa of the National Snow and Ice Data Center (NSIDC), in Boulder, Colorado. Since receiving his B.A. in Physics from the University of California, Irvine, and his Ph.D. in Atmospheric Sciences from the University of Washington, Seattle, Khalsa has been a major contributor to a variety of data programs. His activity in leading the IEEE effort in standards and interoperability for GEOSS is a natural extension of his work in these programs, albeit on a global scale.

Amplified Fire Occurrences in Response to Drought and Vegetation Stress in the Western Ghats of India

map

This study demonstrates the importance of the intensity and severity of drought in contributing to anomalous fire events, an important driver of global fire regimes. While spatial and temporal analysis of fires’ response to droughts indicates the vulnerability of all land cover types, the primary wet evergreen and secondary moist deciduous forests are particularly at risk.

Reporting on European Forest Fragmentation: Standardized Indices and Web Map Services

Screenshot from European forest data centre website. Many of Europe’s habitats are highly fragmented and at risk of further fragmentation as a result of ongoing developments and land-use changes. A study aims to support the reporting on the status and trends of ecosystem fragmentation, motivated by the need of measuring progress toward achieving global and European biodiversity policy targets.

Climate Change Effect on Glacier Behavior: A Case Study from the Himalayas

Graphic showing the change in the glacier boundary between 1962, 1999 and 2008.Due to rising temperatures, Himalayan glaciers are melting faster than in other areas of the world. The benchmark glacier Chhota Shigri has retreated by 950 meters since the 1960s. This paper details the climate-change related effects, using remote sensing and other data.

Building a Consolidated Community Global Cropland Map

Hybrid cropland map of Africa produced by IIASA/IFPRI developed as part of [10]A new Sub-Task on Agricultural Mapping is building a living, community-based consolidated cropland map. The aim is to provide the agricultural monitoring, food security and land use change communities with a better cropland product than currently exists. The product is freely available to researchers and the general public.

Micro-level Drought Vulnerability Assessment in Peddavagu basin, a Tributary of Krishna River, Andhra Pradesh, India

Map of Digital Elevation Model of Peddavagu basin, a tributary of Krishna River basinAssessing the micro-level spatial drought vulnerability in South Central India can assist with coping measures for farmers and others in the region. This study used various thematic maps to derive a village-level drought vulnerability map, which will be useful to drought management and preparedness in the future.
