Under the GADING program, Rumah Energi contributed to support workforce development by building capacity, including links to markets, around low-carbon innovative economic activities related to the use of bio-slurry and Lemna (a common type of duckweed). Duckweed can play a key role in the development of an integrated farming system, which leads to better nutrition for people and animals, reduction of CO2 emissions and more efficient and environmentally friendly production.
Duckweed, along with biodigesters, are crucial to small scale integrated farms as they provide essential protein in poultry and livestock feed, protein which is deficient in rice bran the primary product fed to poultry and livestock on these small farms. Formulated chicken feed is available, but its cost may be excessive to small farmers with limited incomes. Duckweed can replace up to one third of the feed requirements of poultry and this would mean a significant savings for the householder. Duckweed can be fertilized with either manure or with treated effluent from a biodigester. Combining the practices of poultry and livestock husbandry, digestion, duckweed farming and vegetable gardening will provide significant savings to the small householder both in food and in biogas for cooking, lowering the need for bottled gas purchases.
The main idea was to empower 2,400 workforce members (including ≥800 women) adopt and have the skills for integrated farming and waste management systems based on the optimised use of bio-digester and high-nutrient Lemna (duckweed) as organic fodder and fertiliser.
Results of research on sustainable and GHG reducing farming are made available to contribute to farmer skills as well as to actors in the enabling environment, including the education sector. The main activities here are studies into duckweed nutritional content, optimising usage of duckweed and calculating carbon sequestered in the soil, as well as podcasts to disseminate newly generated knowledge.
