Oral Topic 2 - Groundwater and climate change Parallel


Giuseppe Sappa (DICEA Sapienza University of Rome)


The intent of this study, held in the profile research project SECOSUD II, “Conservation and equitable use of biological diversity in the SADC region”, granted by Italian Cooperation and Development Agency, is to understand the natural regimes of groundwater systems and how water resources are stressed by climatic changes in two sensitive and complex areas of southern Africa: Limpopo National park and Kruger National Park.
Limpopo National Park and Kruger National Park are two of the richest areas in the world from biodiversity point of view. That is why, the priority is to make sure that their water resources are managed in a sound and equitable manner.
After gathering regional and local geological data which allowed to define a detailed geological map of two ares of concern, pointing out the main geological units outcropping, the methodological approach has been to assess the potential infiltration, applying the groundwater Budget Technique perfomed for the focus areas. Limited to Limpopo national Park, because of the difficult access to meteorological data, they were available the precipitations historical series, referred to the last twenty years of measurements. Otherwise, because Kruger National Park has a historical weather and rainfall monitoring network, they were available the historical series, recorded in the last fifty years, which allowed an elaboration more complete .Relatively Kruger Park , a spatial temporal analysis has been carried on.
In the perspective of analyzing the impact of climate change, we assessed on the first the average precipitation and temperature data referred to the all 50 years of measurements. On the second, the data have been divided in set of 5 years measurements and it was calculated the average annual precipitation an temperature referred to each of the 5-years cycles of data considered.
The main purpose is to evaluate a trend evolution of meteorological data to identify potential seasonal changes and which is, depending on them, groundwater system response. On the other it is here presented the methodology applied to make meteorological data available for Kruger Park representative also for Limpopo National Park, in the aim, also, of driving to an integrated management of groundwater in these two areas.
