Iran Case Study
study in Iran purpose
assess feasibility of applying VWT strategy to alleviate water stress
assessed feasibility in Iran through what?
- regional crop structure adjustment
- inter-provincial food trade
- socio-economic factors
why might VWT strat be possible in Iran
they have a more centralized government and high level policy and decision making
how was the study done
- model bw and gw in Iran
- assess impact of climate change on water resources (through past and future predictions)
- model wheat yield and cwp in wheat production per province
- analysis of intra-country VWT
why simulate wheat and crop yield, ET, and CWP in each province
to understand which provinces produce better (which will act like the importing country and which will be the exporter)
Different scenarios ran
2 business as usuals, food security, water security, improving irrigation efficiency up to 70%
business as usual scenario results
could produce well but not sustainable for the long-run
food security scenario results
not sustainable
water security
could reach water security provided they partially import cereals from intl markets
improving irrigation scenario results
could produce desired cereal levels while elleviating water scarcity
what types of countries may be suitable for intra-country VWT
large, diverse hydro-climate, agricultural, and economic conditions
national water saving will occur if
water intensive commodities are produced in provinces with high CWP (low VWC) and exported to regions with low CWP (high VWC)
socioeconomic factors should be incorporated into intra-country VWTS
