 Innovating for sustainable development involves creating environmentally friendly, low-cost and contextually relevant technological solutions to some of our most pressing challenges. And I think that we really need to think about what this means, because effectively, unless we commit to developing sustainably, our futures will be at risk. So in thinking about solutions to our developmental issues, we're expected to be both creative, relevant and ingenious, which is what innovation is all about, but we must also be faithful stewards of our environment. We must be inclusive. Innovation must be accessible to all, especially the poor and the vulnerable. Our digital aid technology is a key part of these solutions. When we look at human capital development, for example, everyone is turning to technology in such of new ways to solve the same old problems.
