well first of all welcome to the first workshop and we back well doubt is named it over given to a project which is designed to bring together datasets information from around the world fundamentally to tell us about the city's the places that people occupy what we're mostly interested in gathering is information on all the refer to as the urban form and the urban functions that are current site cities and we need is information for a variety of reasons why is it needed lesson three percent of the land area of the planet is covered by urban areas or cities as we should hope they consist of hard it's permeable surfaces and they also consist of buildings which are proximate to each other the consequence of this is that they dramatically change the near-surface climb they redirect water away from the soil and intro month they redirect energy away from of operation into heating of the overlying Alastair so when the best known examples of this of course is the other key challenge but there are also cases where activities are concentrated it's worth traffic is focused for commercial activity is focused and for industrial production focused that means that they are a source of a major amount of anthropogenic activities and as a consequence of waste generation to the atmosphere these are off c of effects on air quality on water quality at all scales so for example it is estimated that more than fifty percent of the direct emissions of greenhouse gases the atmosphere originated from just a three percent around area time now our objective in this particular class this workshop is to try and find out information for cities around the world collecting a clear consistent mile between actually do comparisons between cities more than half the planet live in cities now and even as the population of planners projected to fall the population two different cities is set to continue to rise that means that for most people on the planet the urban environment is the environment which they are most familiar with which they occupy most darling we know very very little about cities work next to nothing and once you get outside economically prosperous part of the world there's a very great information on cities what distinguishes projects from other projects what other projects try to us about the extent of cities to tell us about areas that urbanized are not organized but they tell us nothing about the details in the city itself tells us nothing about the roughness of the city form by the village that tells us nothing about the empirical services what information there is out there is often collected in an idiosyncratic and inconsistent way which makes it very difficult to compare information one part of the worth to another that's the key to adapt is to try and gather information on cities around the world in a consistent manner so we can do the comparisons who needs it well the people who need are the people are trying to project what kind of the future is going to be like and what the consequence of climate change of the planetary scale will be four cities themselves so we have a convergence of things happening right now enormous number of people are complying cities finally assigns it's capable of addressing things are the coralville city scale an objective here is now to a require and gather information consistent amount of conversations about city's farmers makes you would out different I would argue is that we're using conventional science and scientific information and the former say satellites but differently from any of the projects what we're trying to do is correct the information the innate knowledge the residents of cities around the world have about their own cities so this makes I think would up a different project it's community-based there is lots of information out there that's freely available now they'll tell us about cities what we are missing are the individuals that live in these places to try and to us more details about those places that's what wound up is an attempt to do to bring together those two communities and have shared conversations now I organized this conference in collaboration with a number of other people including a colleague Jason chain and a colleague did see I'm going to ask Belinda to have a brief word about the community aspect of this scientific project which is the gathering information on cities globally using local expertise okay thanks very much mr. al mentioned i'm i'm going to see so i work at the international institute for applied systems analysis this is an institute just outside of vienna and the focus of the institute is global problems so urbanization is therefore one of the the core interests of Yassa i also work in a program called ecosystem services management and a group within that program called Earth observation systems and what we work on there is crowdsourcing and of gene wiki so you'll be introduced to deal with you during the course of the workshop how we can use it we want to discuss new new advances in jewel wiki how it can help us do the data collection so the data collection is the key the crowdsourcing is the key so we use terms like crowdsourcing citizen science volunteered geographic information we use them as synonyms now there are some nuanced differences between these terms but basically this is about involving the crowd the crowd can be citizens the crowd can be experts in collecting information in analyzing that information or we can engage with that community at an even higher level and they can help us with research so they can even for example come up with hypotheses they can help us with the experimental research design ok so the involvement of the community is a core part of the wood up project now why is citizen science and this community-based approach suddenly come to the fore in fact citizen science has been around for a very long time I mean centuries so if you look at someone like Alfred Russel Wallace if you've heard of him he he was just a citizen particularly interested in understanding processes so based on empirical observation he was actually observing evolution the processes of evolution but he actually had to finance that work by collecting exotic birds and then selling that but his real passion as a citizen was trying to understand happening on the ground versus someone like Charles Darwin who is really in academia and at the same time coming up with these theories okay so citizen science has been there for a long time but why is it suddenly become a big buzzword citizen science crowdsourcing why are those terms suddenly come to the fore and that there's I think three reasons the first is this I think everybody probably has one of these and I've resisted having one of these for a long time but now I have one I think if you don't have one you're certainly going to happen soon but the key is not necessary that you'll have one it's the fact that mobile penetration in places like Africa South America Asia is exponentially increasing and with this we can literally map the world so I can take a picture it's geo-referenced I can tell a story about that picture it's my interpretation of the landscape I can map it I could tweet about an event I can see a flood happening I can feel an earthquake and suddenly I become part of a community based alert system or disaster management is a great example where citizen science is being used people going out post-disaster mapping things you know that's really helping communities understand and respond to these events and I think openstreetmap is probably one of the most successful examples of crowdsourcing or volunteered geographic information crowdsourcing tends to be more sort of the business side citizen science tends to be more the sort of scientific research stuff but openstreetmap was started simply because people who are tired of having to pay so much money for basic data and this is data being collected by national mapping agencies which are publicly funded so Steve coast in fact started this initiative in London and sort of said okay that's just not the world ourselves now open stream out is a very big thriving and sustaining community collecting the sorts of information that we can use as part of this initiative so I think some of the discussions will will be about how can we use all these disparate pieces of information that are out there to help wud up I should say thank you to number groups one group is I asset Linda's book and the European Union supplied allow the following via cost via I answer the other group is argonne national laboratory for the support for many people to attend this conference on tuesday of the conference I also have to thank you see obviously my own school job tree plant in foreign policy and some of the funds that were derived from ice uch by the international association for open trials have also been used to support the conference this point buddha is an idea and that's ology is what we're going to be exploring over the next three days is whether we convert some of these ideas into a reality so I'll hope at the end of the stick project effort is enthused about the project and what possibilities are it's a possibility that involves people who actually live in cities telling us about the places they live combined with people with expertise in particular techniques utilizing modern technology and combine them to them to tell us about or more than half the planet spend most of their lives so thank you you
