Payments for Watershed services (quality & quantity) Paying land owners Purchasing land Nutrient trading -Nitrogen, phosphorus, sediments How? Restoring, creating, or enhancing wetlands Maintaining forest cover Reforesting Adopting ‘best’ land use management practices Why? Reduce pollution in local water supplies Filtration and regulation of water flow Controlling for floods Minimizing soil loss and sedimentation ( Beto Borges,2006 ) III.5. Duck weed Another asset could be duck weed. Still in a developing stage but looking ferry promising. In the Netherlands there are at least 7 different species of duckweed, belonging to 3 genera and 1 family. Lemna sp,Spirodela sp and Wolffia sp. Wolfia spearea is eaten in Thailand and other countries by people ant cattle already for centuries. Duckweed is easily crown on static waterboddys . It multiplies very quickly and shown in the quick scan in table 2 the value and energy that has to go in versus the value and energy out looks very promising. It is possible by rising nutrient levels and creating optimum conditions to increase the volume of duck weed. As it is possible for Duckweed to contain more protein cultivated on ha/yr as soy and soy being the number one protein crop in the world. In table 1 a overview of the main protein rich crops that are cultivated are shown. Farming duckweed good be very promising. It can be used for food consumption for human, cattle or fish feed. Soy is one of the most important sources of protein in the world. On average the world produces approximately 241 million tons soy/year. ( Cees Gauw 2014)
