Although gardens and small-scale animal husbandry may not constitute major economic activities , they are important supplementary food sources that can have a positive effect on food intake and nutrition status . There are important ethical and pragmatic limitations with these local schemes . There are also changes in our understanding of practices of creativity and innovation - from the idea of the isolated individual ' genius ' to the concept of ' communities of practice ' , where reflection and feedback are important collaborative processes.In this context , educational agendas are shifting to address ideas about how we can create personalised and collaborative knowledge spaces , where learners can access people and knowledge in ways that encourage creative and reflective learning practices that extend beyond the boundaries of the school , and beyond the limits of formal education.It is in the light of these new educational agendas that Futurelab is interested in the emerging practices of social software .

Thus , specimens collected from this region will be important comparative material for several species .
