Which geographic theme would include how a group of people learned to survive with a limited water supply?

In 1894, a treaty was signed to allow Japanese workers free immigration to the United States. However, the number of Japanese immigrants increased quickly in California and tensions began to run high. In August of 1900, Japan agreed to deny any requests by Japanese workers for passports to the United States. However, these workers found a way around this. They simply requested passports to Canada and other nearby countries, then moved to the US. Eventually, the California School Board arranged for all Asian students to be placed in a segregated school. The US government intervened and the Gentlemen's Agreement of 1907 was born. This agreement mean Japan would agree that the US could deny passports by Japanese workers to enter the US from Japan or from other countries. Following this agreement, the California School board agreed to desegregate the schools.
