  • Green and Clean Energy: Microalgae as a source for fuel

    Continued use of fossil fuels has led to diminishing fuel reserves and serious environmental issues. CO2 emitted from various sources like burning of fossil fuel, has been regarded as a major green house gas responsible for climate change. Therefore, there is a need to review the situation and find an economically viable, green and clean alternative to fossil fuels. Microalgae has shown the promise for such an alternative as they are rich in lipid content. Further, their higher rate of production and wider adaptability make them perfect feedstock for biofuel production. Microalgae can be grown in waste water which in turn reduces pollution load and also provides a viable option for waste water treatment which is a costly affair. Microalgae can be exploited for bioethanol, biomethane, biodiesel and biohydrogen production. Biodiesel production from waste water grown microalgae could be a sustainable and potential option for future programme on renewable energy sector on clean and green energy.

  • Climate change and food security

    Climate changes have started showing its impact on water resources and agricultural yield worldwide. Majority of the countries in arid and semiarid areas totally depend on precipitation and rivers originating in tropical and temperate regions. The overall water stress is continuously increasing and due to climate change a sharp decline in precipitation is expected in these regions. Agricultural sector and food securities are threatened and if the basic adaptive measures such as changes in crop pattern, crop breeding and types and innovative technologies, which use less water are not used global food production especially in arid and semi-arid areas will further decline.

    Increasing global population, which is 7.5 billion today, is predicted to rise over 9 billion by 2050 (UN DESA, 2013) and changes in diet are driving up the need for food. Cereals are the important staple food throughout the world especially rice, wheat and maize. Intensive agricultural systems that derive much of global food production are far from sustainable and a ‘business as usual’. Approaches to meet the increased demand for food will lead to significant depletions in natural resources. The production and application of chemical fertilizer is the major source of pollution as well as the major use of energy in agricultural systems.
