Environmental Data Science and AI Summit Speakers

We have an exciting line up of speakers ready to share their expertise:

Dr. Mario Krapp (GNS)

Title: A Bayesian approach to reconstructs the climate of the past

Abstract: To understand past climates, we are looking into the geological record. However, key information like temperature and rainfall cannot be directly observed. Instead, we rely on proxies such as fossils, biomarkers, stable isotope ratios, pollen abundances, and sediment types. The paleoclimate community has developed empirical methods to interpret these. However, these methods are often challenging to interpret and provide limited insight into the underlying climate drivers. In this presentation, I introduce a Bayesian approach to infer past climate changes from geological records. I will demonstrate the use of Bayesian Inference in the paleoclimate context and discuss how this approach can address complex problems more generally.

Short bio: Mario is an environmental data scientist and interested in (almost) everything related to the Earth system. Mario spends his days figuring out how we can we learn from data, how we can better integrate models and data, and how we can make informed decision using the best of both worlds. Examples are future contributions of Antarctica to global sea level rise or past climate sensitivities inferred from the geological record. Mario is currently involved in the Antarctic Science Platform and the MBIE Endeavour programme Te Ao Hurihuri: Te Ao Hou, Our Changing Coast.

Title: AIML for Segmentation of Individual Tree Crowns and Salinity Prediction in NZ Oyster Farms

Abstract: This presentation talks about two pieces of works using AIML for image segmentation of individual tree crowns and salinity prediction for oyster farms in NZ, both of which are related for NZ environment. New Zealand has 24% of its 270,000 km2 land covered in forest and actively supports and promotes urban regreening in many of its cities. Sustaining and enhancing biodiversity and healthy living environments are priorities for New Zealand that require careful management of trees in urban areas and forests. This talk will first provide some pieces of work of CDSAI at VUW, collaborating with MWLR, on segmentation of individual tree crowns images for the Wellington City using Convolutional neural networks and variations particular different version of Yolos. Meanwhile, NZ oyster farms provided a sustainable and profitable export for New Zealand, but are sensitive to changes in salinity that can cause significant crop loss if they persist too long. Recent extreme weather events have been leading to increased periods of low salinity, putting the farms at risk. This presentation will then discuss three different methods to assess the viability of salinity prediction systems, including a statistical model, a genetic programming (GP) based symbolic regression model and a convolutional neural network. The results show that both GP and CNN performed better than statistical models to predict salinity, the CNN generalised better on extreme weather conditions, and the GP-learned models are more interpretable. If time allows, some initial work, collaborating with ARC, on climate modelling will be discussed using AI and machine learning.

Title: The integration of AI and ML into the operational and planning phases of agrivoltaic systems

Abstract: The required energy transition to reach a net zero carbon economy by 2050 will see the large uptake of utility-scale solar photovoltaic (PV) electricity generation. Scenarios for Aotearoa New Zealand project in the order of 10 GW – equal to the current generation capacity in the country – over the next two decades. Conventional solar farms have seen the conversion of productive agricultural land with solar arrays and sheep grazing for vegetation management. This is a concern as half of the country’s land area is utilised for agricultural purposes. Globally, agrivoltaic systems have emerged as an innovative solution to address this concern. Optimised systems allow for dual land-usage to both generate electricity and continue with efficient and effective agricultural production. The placement, orientation, and spacing of solar arrays directly impact crop growth and yield, making it crucial to minimize shading while maximizing energy production. Traditional optimisation approaches, such as linear programming, have been beneficial in this context but struggle with the complexity and dimensionality of agrivoltaic systems on a more granular level with more variables to simultaneously account for. The integration of AI and ML into the operational and planning phases of agrivoltaic systems presents a ground-breaking leap forward. These advanced algorithms have the capacity to analyse vast amounts of data, identify intricate patterns, and uncover correlations that traditional methods might overlook. AI and ML provide valuable insights into system performance, leading to data-driven decisions for enhanced efficiency and productivity.
