Okay. I will talk a bit about the past to contextualise where we are and, before concluding, I will talk about the key issue the committee has raised about the retention of research groups. With regard to the past, members may or may not be aware that in 1999, we had a Foresight report which reviewed where Ireland was in the research and development space and where it should go in terms of scientific research. That group identified information and communications technologies, ICT, and biotechnologies as the two target areas in which we should work.
The first national development plan, NDP, between 2000 and 2005 invested €1.3 billion in science research, about half that being handled by the Higher Education Authority, HEA, for buildings and capital improvements in the third level sector, and the other half being spent on researchers. SFI has largely been responsible for the latter half in that period. Up to 2005, we disbursed about €650 million which has paid for about 1,200 researchers in 140 individual research groups. That constituency of 1,200 includes 200 lead scientists or principal investigators — PIs as we call them — 500 PhDs and 500 postdoctoral researchers, people who move on from a PhD to a research position for three to six years. That is the sort of group we are worrying about retaining in some way.
The second NDP programme was announced recently which, under the strategy for science, technology and innovation, SSTI, will spend €3.8 billion over the next five to seven years. SFI will be responsible for a lot of what could be called the people part of that, accounting for approximately €1.3 billion of that spend. The figures I have provided for 2005 have moved on a bit to a spend of approximately €750 million, funding 2,000 researchers at this stage. That is the general context within which we are working.
The key issue is attracting and retaining these people. The standard research group is a hierarchy in the medieval, feudal sense. At the top is a lead scientist or principal investigator, a PI. Beneath that are a number of post-doctoral people who are the middle management of the group. At the bottom, one has postgraduates, PhD and MA students. We are worrying about how one can allow people to build up such groups and retain the people in them over time.
There is no mystery as to how one does it. I would see three key things as being critical. The first and most important thing in science is always the international reputation of the researchers involved. If one does not have an international researcher, one will not attract people to, or retrain them in, the work one does. Science is a globalised business and one has to be the best in the world at it. If one is the best in the world, then people beat a path to one's door to work.
The second requirement is money to fund those people, so a stable and robust funding environment is needed. There must be an assurance that this country is committed to investing in the area, and that if people come here there will be a future for them. The third and final element that is important to the retention of such people is that there are prospects. Like anyone else, they will ask what the job prospects are. PhD students will look forward to see if there are postdoctoral opportunities for them. Postdoctoral researchers will examine whether there are academic possibilities for them. They will want to know if there are jobs in research and development companies in this country. Those three elements come together as the key attributes that will help us to attract and retain people. I see those as being the key factors.
One may step back and ask why are we doing all this. Members may wish to pose questions with regard to enterprise and I will elaborate on that later. It is similar to the Lemass-type investment in third level education in the 1960s through to the 1970s. There was a certain point at which we said that second level education should be free, which was important. There was another point at which we said that third level education should be free. Now we are looking at what is sometimes referred to as the fourth level, which is research and development at PhD level. We realise that to be an advanced, developed western economy, we must have a fully funded sector at that level as well. If we do not, there will be serious repercussions. Currently, we do not really look like a mature economy. We have certain things which are well developed while other areas are over-developed. The research and development part of it is an innovation and a key ideas generation for the enterprise sector. If we do not get it right soon, there will be long-term consequences for the robustness of our economy.
