[[File:Songhai farm ( gas station).jpg|thumb|right|The Songhai zero waste farm in [[Benin]] was started by Father Godfrey Nzamujo in 1985. It is now recognised as a centre of excellence by the UN and its philosophy and methods are now studied and followed by thousands in Africa.

In sunny climates, a one hectare zero waste farm can produce over 1000 litres of oil in a year from the [[chlorella]] microalgae grown on biogas digester effluent in a 500m<sup>2</sup> shallow pond.

Zero waste agriculture is a type of sustainable agriculture which optimizes use of the five natural kingdoms, i.e. plants, animals, bacteria, fungi and algae, to produce biodiverse-food, energy and nutrients in a synergistic integrated cycle of profit making processes where the waste of each process becomes the feedstock for another process.
History
[edit]The integration of shallow oxidisation ponds of microalgae was demonstrated by Golueke & Oswald in the 1960s. The widespread global implementation of these systems can be largely credited to Prof George Lai Chan-Yu-Thim (2 March 1924 Mauritius-8 October 2016 Mauritius) from ZERI.[2] Zero waste agriculture is now practiced in China (ecological farming), Columbia (integrated food & waste management systems) & Fiji (integrated farming systems), India (integrated biogas farming), South Africa (BEAT Coop & African Agroecological Biotechnology Initiative) and Mauritius. The Brazilian government has adopted integrated farming system as a major social technology for the uplifting of marginalized and subsistence farmers through coordination with TECPAR.[3]
Zero waste agriculture combines mature ecological farming practices that delivers an integrated balance of job creation, poverty relief, food security, energy security, water conservation, climate change relief, land security & stewardship.
Practice
[edit]Zero waste agriculture is optimally practiced on small 1-5 ha sized family owned and managed farms and it complements traditional farming & animal husbandry as practiced in most third world communities. Zero Waste Agriculture also preserves local indigenous systems and existing agrarian cultural values and practices.
Zero waste agriculture presents a balance of economically, socially and ecologically benefits as it:
- optimizes food production in an ecological sound manner
- reduces water consumption through recycling and reduced evaporation
- provides energy security through the harvesting of biomethane (biogas) and the extraction of biodiesel from micro-algae, as a by-product of food production
- provides climate change relief through the substantial reduction in greenhouse gas emissions from both traditional agriculture practices and fossil fuel usage
- reduces the use of pesticides through biodiverse farming
Certification of such farming practices is both challenging and an opportunity.[4]
