There are many impediments to bringing about a more environmentally sustainable society but one that is often overlooked are the significant and interesting computational challenges that need to be solved in sustainability domains.  The field of Computational Sustainability attempts to connect research in the computational sciences to hard sustainability problems such as invasive species management, wildlife reserve design and sustainable forest management.  I will give an overview of some of these domains with a focus on spatial decision making problems where actions must be chosen across a large physical landscape.  These problems can be modelled as using Markov decision processes but the scale, complex dynamics and spatial correlations make these problems hard to solve using traditional algorithms. I will describe research I have been involved with obtaining approximate solutions to spatially factored MDPs using policy gradients and sample based planning on invasive species, forest harvest and wildfire prevention problems. I'll also outline future challenges in spatial planning which provide opportunities for AI and Machine Learning research to make an impact on making sustainable world more computationally feasible.
