In the Andes mountainous region of South America grasslands known as páramos provide important ecosystem services like sustaining biodiversity, securing carbon sequestration and providing water storage. However, many páramos regions are subject to land use change due to expanding agriculture, intensified grazing and land burning. These are usually caused by socio-economic factors driving local communities to increase their income generation. Trying to achieve a better understanding of the páramos is often restricted to exploring specific details and does not follow an integrated approach or a comprehensive ecosystem analysis.

In this research the focus is on better understanding the dominant ecohydrological processes and their interactions. An integrated approach is followed using in-situ measurements, field experiments, laboratory analyses, and numerical modelling. Also, different hydroinformatics tools are used to identify and quantify the ecosystem services provided by the páramos. Moreover, a framework is developed that allows a more realistic quantification and mapping of the main ecosystem services. The approach was carried out for a test site in an Ecological area in North Ecuador. The findings show a clear difference in ecosystem services depending on their altitudinal range and type of vegetation. These results can be used to further develop environmental management and landscape planning strategies, in order to better meet the social goals. This research is aligned with the priorities advocated in the IPCC Report (2007) 'to improve representation of the interactive coupling between ecosystems and the climate system', and with SDG #15: Life on Land 'By 2020, ensure the conservation, restoration and sustainable use of terrestrial and inland freshwater ecosystems and their services'.

About the Author

Veronica Minaya is a PhD candidate in Eco-hydrology at UNESCO-IHE and TU-Delft, the Netherlands. She has a background in Civil Engineer with two Msc degrees in Water Resources (2008) and Environmental Sciences (2010). She has extensive fieldwork experience in Ecuador (highlands and rainforest regions) and in Kenya (Mara River). Veronica's PhD research uses a biogeochemical model to look at carbon, nitrogen, water cycles in a combined glacier - grassland catchment in the Ecuadorian Andes. She is also interested in research development, and women & youth empowerment. Veronica is actively involved in youth organizations, president of the IAHR-YPN Delft and member of the Water Youth Network.

About the Series

IHE Delft PhD Thesis Series

IHE Delft PhD programme leads to a deepening of a field of specialisation. PhD fellows do scientific research, often with conclusions that directly influence their region. At IHE Delft, PhD researchers from around the world participate in problem-focused and solution-oriented research on development issues, resulting in an inspiring research environment. PhD fellows work together with other researchers from many countries dealing with topics related to water and the environment.

PhD research is often carried out in the ‘sandwich’ model. Preparation and final reporting – the first and last portion of the programme – are carried out in Delft, while actual research is done in the fellow’s home country, under co-supervision of a local institute. Regular contacts with the promotor are maintained through visits and long-distance communication. This enables researchers to employ solutions directly to problems in their geographical region.

IHE Delft PhD degrees are awarded jointly with a university. The degrees are highly valued and fully recognised in all parts of the world.
