Thesis time!

The time has come to face the final challenge in the UNIGIS Master program: the thesis.

Being an ecologist, I wanted the work to take into account my interests, both personal and professional. And, I am currently working on a project regarding the world-famous Galapagos Islands in Ecuador, so I thought why not combine both. After some research, I think I found my topic: Identifying terrestrial conservation priorities in the Galapagos Islands, based primarily on anthropogenic threat assessment.

The conservation of the famed Galapagos Islands experienced two crucial points during its history: it started officially in 1959 with the creation of the Galapagos National park, and was later expanded to the marine ecosystem by forming the Galapagos Marine Reserve in 1996. However, by that time, the archipelago had experienced severe human influence that first started with the discovery of the Islands in 1535, intensifying strongly with the beginning of organized colonization in 1983 and continuing relentlessly ever since. Today, the Galapagos NP encompasses 96,7% of the islands (7 731 km2) and the Marine Reserve reaches up to 40 miles from the Islands (138 000 km2), but anthropogenic influence is still great and poses a significant threat to the conservation efforts.

The primary factor of influence is tourism, which has sky-rocketed in the last decades, causing strong immigration of the Ecuadorean population from the continent, bringing with it almost complete dependence of energy, food and water from the continent, and causing a host of problems: introduced and invasive species, illegal and uncontrolled fishing, contamination of aquifers and soil, inadequate or (for the most part) inexistent solid waste and residual water management, rampant urbanization, among others. These factors keep altering the fragile ecosystems of the Galapagos Islands, despite the constitutional protection that Pacha Mama (Mother Nature) enjoys in Ecuador and the continuous efforts of the NP and Marine Reserve management.

Despite the strong scientific interest in Galapagos, there have been few attempts to quantify the anthropogenic influences suffered by the ecosystems. However, it is precisely by means of a thorough evaluation of human risk factors risk that conservation of the Islands should be managed, in order to aim its valuable and costly efforts into particular human activities, specific areas and species.

The objective of the project will be to perform an ecological risk assessment for terrestrial conservation in the Galapagos Islands based on anthropogenic risk factors, and identify areas that represent conservation priorities.

So… the next step is to gather all the information available in order to identify, quantify and spatially delimit the influences that the terrestrial ecosystems of Galapagos face due to various human activities, and also to identify and localize the distribution of target terrestrial species on the islands. With that, it will be possible to identify areas that require particular conservation efforts, based on an overlay of quantified threats and identified species, and finally to produce a map of conservation priority areas.

So now cross my fingers and start working…
I may not have gone where I wanted to go, but I'm sure I ended up where I needed to be.
