Lizaida graduated from Florida Atlantic University in 2013 with a Bachelor of Arts in International Business and a minor in Italian. While at FAU, she was a member of the Phi Theta Kappa Honor Society and the Pre-Law Society.

Motivated by her passion to learn about the legal system in the U.S., as well as those in other countries, she decided to go to Barry Law School. During her first year, she began to learn about laws relating to water rights in Florida and became concerned about the availability of freshwater in the state in the near future. She also became proactive in following the forecasts of sea-level rise in Florida in the future.

In an effort to resolve some of the water issues that continue to evolve in the state, Lizaida traveled to the Netherlands and completed the United Nations Water Law Program in Delft. During her time in the Netherlands she learned how, in preparation for a climate changed future, the people of the Netherlands are designing and constructing billions of Euros worth of project to ensure the well-being of their nation. She studied water management as experienced in a nation situated below sea-level and learned how other countries are meeting the present global challenges by building a strong foundation of knowledge to improve water management practices.

Lizaida was accepted into Barry Law’s Environmental & Earth Law Clinic where she had the opportunity to work with the Apalachicola Riverkeepers and the Florida League of Women Voters to advocate for the protection and restoration of the Apalachicola River, Apalachicola Bay and adjacent lands. She is currently continuing her work with the clinic as an Advanced Environmental & Earth Law Student and further focusing her efforts in saving the Apalachicola River and Bay as well as working on other local projects. During her time as a fellow, she hopes to help develop laws that take into account the importance of preventing harm to our Earth rather than restoring the harm once it is done. She also aspires to continue being involved in efforts to protect and restore our springs and rivers and promote better water management practices across the state.
