Mapping multiple climate-related hazards in South Asia

Abstract

170 Research ReportsThe publications in this series cover a wide range of subjects-from computer modeling to experience with water user associations-and vary in content from directly applicable research to more basic studies, on which applied work ultimately depends. Some research reports are narrowly focused, analytical and detailed empirical studies; others are wide-ranging and synthetic overviews of generic problems.Although most of the reports are published by IWMI staff and their collaborators, we welcome contributions from others. Each report is reviewed internally by IWMI staff, and by external reviewers. The reports are published and distributed both in hard copy and electronically (www.iwmi.org) and where possible all data and analyses will be available as separate downloadable files. Reports may be copied freely and cited with due acknowledgment. About IWMIIWMI's mission is to provide evidence-based solutions to sustainably manage water and land resources for food security, people's livelihoods and the environment. IWMI works in partnership with governments, civil society and the private sector to develop scalable agricultural water management solutions that have a tangible impact on poverty reduction, food security and ecosystem health.

Assessment of Large Seed Banks Requirement for Drought Risk Management in South Asia

“…Many locations in central and eastern India, western Nepal and Bangladesh, and some places in Afghanistan had moderate to extremely dry condition in the last 47 years. These results are consistent with mappings of drought patterns in the region [26,27].…”

Review of climate change science, knowledge and impacts on water resources in South Asia. Background Paper 1

“…Source: Amarnath et al 2017. Note: APHRODITE and TRMM are gridded rainfall products (Yatagai et al 2012;Huffman et al 2007).…”

“…It is predicted that some 25% of the Indus Delta, already retreating because of a sharply reduced silt load, will be submerged under a 2-m sea-level rise (Mirza and Ahmad 2005). Notes: The value of exposure was calculated using a composite hazard index accounting for the rate of sea-level rise, the coastal slope, elevation, tidal range, tsunami arrival height and geomorphology (Amarnath et al 2017).…”

“…Table 6.1 provides a list of climate-related risks for each country, ranked according to three levels (high, medium and low). The table is based on a literature review, with a focus on the assessment proposed by Amarnath et al (2017) and disaster data available at http://www.emdat.be/. This ranking corresponds to the current situation.…”

“…Note: GLOF = Glacial lake outburst flood. Amarnath et al (2017) quantitatively and systematically assessed multiple baseline climatic risks in South Asia (excluding Afghanistan), including droughts, floods, extreme temperature (heat waves), rainfall and sea-level rise. Erosion and siltation-related risks were not included in this analysis.…”
