Farmers in PNG live with too much and too little rain. Too much rain is the main reason farmers make vertical ditches in their steep landscapes when making gardens.
However, these same ditches carry away precious top soil. Depending on location topsoil maybe shallow on top of relatively infertile sedimentary deposits, uplifted by tectonic action.
CDWAI shows and encourages and works with women and men to shift understanding and establish trials with simple barriers – to reduce soil erosion. We go further than just establishing trials. We measure – weigh – the soil that would have been lost. It is an eye opener to fill buckets with soil that has been trapped behind simple barriers.
