 I'm Katrin. I'm working as a joint appointee with Ilri and Ilmi here in Addis and the project I'm working on is looking at improving water productivity of mixed crop livestock systems. So we're looking at small holder systems and trying to find ways to improve water productivity. And so we're looking at water use of different feed types, how livestock use the feed types to come up or to produce different products and services, how these products and services contribute to farmers' livelihoods and then how different interventions can actually improve the productivity of these systems. And things we find out is that different feed types have a different influence on this water productivity, but also providing water to the livestock nearby the homestead is very important because then animals save energy that otherwise they would lose for walking. They save that energy and they can use it for productive purposes like milk and growth. And so our project is not only looking at bio-physical issues but also at institutions and policies. So other people are working on these aspects. I'm looking more into the bio-physical stuff. And our project is working basically here in Ethiopia but also in Zimbabwe and we're collaborating with similar projects in India. And so we're trying to expand our work to other regions.
