Improved cultivation techniques

  • Background: Mass cultivation of algae for biofuel production has focused on the use of open ponds or closed bioreactors. Both approaches depend upon routine liquid culturing of the algae and require the removal of large quantities of water at the time of cell harvesting and subsequent extraction of desired products. This invention proposes the use of porous inert membranes to support the growth and subsequent harvesting of the algae.

    What is Micro-algae

    Micro-algae are a group of unicellular or simple multicellular fast growing photosynthetic microorganisms that can conserve CO2 efficiently from different sources, including the atmosphere, industrial exhaust gases, and soluble carbonate salts. Micro-algae act as a major system for converting atmospheric CO2 into lipids under sunlight and increase the output of algal oil. The enzyme acetyl Co-A carboxylase (ACCase) from micro-algae catalyzes the key metabolic step in the synthesis of oil in algae.

    Description of the project: The Kagera river, a tributary of the Nile, is being threatened by silting due to unsustainable farming methods. Its river basin is a very rich agricultural ground supporting 16.5 million people in Burundi, Rwanda, Tanzania and Uganda. The project aims to improve and modernize current farming  methods, in order to improve food security and ensure resilient livelihoods for people and animals living in this area. Groups of  50 new beneficiaries are trained every month on farming methods, followed by a tree-planting scheme by the river.

    Objective

    Rice cultivation system is directly affected by climate conditions and changes. This study aimed to analyze the impact of climate change on the water requirements of agricultural reservoirs using a reservoir water-balance model that includes climate change data, the paddy rice growing season and changes in land use. The results showed that due to increasing temperature, transplanting and heading dates were delayed 5-25 days and 0-10 days, respectively, in comparison to the baseline. The decrease in rates could be the result of IWR and increasing watershed runoff (average 10.7% to 27.0%).
