Ubon Chansoi has lived in a modest wooden home in rural Thailand for about 60 years, farming and rearing fish for a living that is now threatened by an ambitious plan to turn agricultural land in her village in Chachoengsao province into an industrial zone.

Chachoengsao is one of three provinces covered by the Eastern Economic Corridor (EEC) project that includes several industries, a high-speed railway line, an airport and upgrades to two deep-sea ports in an area of about 1.3 million hectares.

The $45 billion EEC project is a centerpiece of the Thai government's efforts to boost economic growth and encourage investment with speedier approvals, tax breaks and special visas for investors, as well as land leases for up to 99 years.
