11. The 1998 Floods in Bangladesh
•From early July to the end of September 1998, floods covered much of Bangladesh
•At their peak on 7 September, 1998, 51 percent of the country was under water.
•The floods caused 2.04 million tons of losses to rice production , equal to 17.9 percent of target national rice production for the first half of 1998/99.
•Yet, no reported deaths from starvation occurred after the flood and food markets were stable.
12. Bangladesh 1998: Private Sector Imports
•As part of its price stabilization strategy, the government of Bangladesh encouraged private sector imports through the elimination of a 2.5 percent import tax on rice and other measures.
•In response to market incentives, hundreds of private sector traders imported an estimated 2.42 million tons of rice from July 1998 to April 1999 (according to official data).
•Government net distribution in this period was 1.58 million tons, only 0.19 million tons more than originally planned.
13. Bangladesh 1998 Floods Household Borrowing
•In order to cope with the loss of incomes from the floods, most poor and flood-exposed households borrowed heavily from private sector sources.
•Even fifteen months after the flood, household debts still averaged about 1.5 month’s average consumption for the 64.2% of flood-exposed households in the bottom 40% of the expenditure distribution who were in debt.
•To eliminate borrowing following the flood would have required a transfer of approximately $100 for each household.
•At the national level, total private borrowing by households may have reached $1.0 to $1.5 billion, equivalent to nearly one- fourth of total government expenditures in 1998–99, and about double of the combined annual loan disbursements of GrameenBank and BRAC at that time.
14. Bangladesh 1998 Floods Household Coping Mechanisms
•Private borrowing was the dominant coping mechanism for flood-exposed households
•Public and NGO interventions, though well targeted, were too small to have a major impact on household food security
•Poor households bore the weight of substantially increased debt more than a year after the floods
•Given the sharp increase in debt for the poor, there was a need for additional efforts in providing rural employment, transfers and credit to poor households following the flood
15. SOUTH ASIA –LESSONS Incorporating Livelihood Strategies in Relief and Rehabilitation
•Social protection has to be prioritized in a disaster response so the most vulnerable groups are protected.
–Awareness-raising is an important component to ensure participation.
•Encourage active participation of key stakeholders from a multi-sector base as well as the community, in the decisions made for each program.
–Activities, where possible, should be linked with government, local enterprises, organizations and industries.
•Interventions need to be tailored to target specific needs of different groups
•Enhance livelihood opportunities for people through provision of temporary work schemes
–debris clearance, construction, public awareness, project management, assessments, etc.
16. SOUTH ASIA –LESSONS Incorporating Livelihood Strategies in Relief and Rehabilitation
•Partnering with NGOs
–in sustainable livelihood support (provision of seeds and tools, animals, capacity building).NGOs can play a big part in relief initiatives and micro- crediting.
•Developing forums and focus groups for particular industries
–to pool resources, share equipment and experiences, and support each other as well as plan for the future.Setting up a community funding scheme can help people restart businesses.
•Availing of loans
–from the government or private sector and utilizing government grants can fill consumption shortfalls.
•Enhancing skills through training
–to supply more construction sector artisans (masons, carpenters, electricians etc) and training them in hazard-resistant construction technology can upgrade the future workforce.
•Compensation should be paid to people without delay to enable them to rebuild their lives.

Heat Stress Increases Long-term Human Migration in Rural Pakistan
Mueller, Valerie; Gray, Clark; and Kosec, Katrina. 2014. Heat stress increases long-term human migration in rural Pakistan. Nature Climate Change4: 182-185.
18. Migration and Income Data
•Pakistan Rural Household Panel Survey (1986- 1991) collected by IFPRI
–Punjab, Sindh, and NWFP
–726 households from 41 villages
–Pre-migration individual and household information taken from 1991 for migration regressions
–Panel used to estimate weather effects on income
•2001 (PIDE) and 2012 (IFPRI) Tracking Surveys for 1991 PRHS
–Create person-year dataset over 21-year period

21. Summary of Findings
1.Controlling for other factors, temperature extremes (but NOT FLOODING) have a statistically significant effect on the long- term migration of men in Pakistan.
-Extreme high-temperature scenario predicts a 12 percent increase in male migration
2.Annual agricultural and non-farm income affected by temperature
3.Asset and land poor are more likely to move which is consistent with low financial barriers to move and effects on non-farm income

23. CC Conclusions
•Hydrological impacts of climate change vary widely across scenario for the Indus River basin; considerable uncertainties exist in current climate model projections
•The impacts on crop yields of key staples are always negative, primarily due to higher temperatures under CC
•A combination of very high improvement in agricultural R&D and improved irrigation efficiency can achieve the best outcomes for Pakistan under climate change
•Increasing reservoir storage alone will unlikely improve crop productivity and production; however storage is important to address intra-and inter-annual water variability
