The environmental farming scheme has been a good success thus far and has had good uptake. As we move forward, we will seek to make amendments and changes to it to deliver further success. One of the things that I really want to look at is what are termed riparian boundaries, which are the boundaries along the rivers. I indicated earlier that that will reduce run-off towards rivers from the land; where the land is rich in nutrients, more of those nutrients will be kept in the soil. It is important to keep those nutrients in the soil and away from the waterways. Appropriate tree-planting may be something that could assist us in doing that.
