An Indian perspective of new generation of farming: Vertical farming

The way we grow our food has to change substantially in future. World population is set to increase by 9.1billion by 2050 from 7.79billion in 2020. With an exponential increase in population, according to FAO , there must be an increase of 70% in food production to satisfy future needs. In the process of becoming food secure using current land-use change activities in future, we might end up converting all of the forests into agricultural cultivation land. Currently, 70% of freshwater withdrawal is only for agricultural activities. This technique of growing crops is highly unsustainable. Agricultural land in past was created by clearing forest areas. But this is no longer an option. With more and more agricultural land disappearing and intensifying desertification, the necessity for a feasible solution is a must. We need to have more food production per unit area. Traditionally it was achieved through the use of fertilizers. But the chemicals involved in the process are far more deg

Greenhouse gas emissions source and sinks- IPCC 1992

Greenhouse gases are the sole reason for the temperature increase in the environment. The Intergovernmental Panel on Climate Change(IPCC) assessed the sources and sink of these gases. This report was published in 1992 which was an update on the IPCC first assessment report . It neither confirmed or justified the first assessment report. But it was important because it led to an increase in a deep understanding of this global problem. Increase in global heat mainly driven by CO2 emissions has fostered widespread concern. Carbon dioxide The two main reasons for the increase in CO2 is fossil fuel consumption and land-use change emission. The key issue is to identify the processes controlling carbon in and out of the atmosphere and how to measure them effectively. Global land-use change(especially deforestation) and carbon fluctuation with process controlling release and uptake(particularly in the biosphere and the oceans) are two concerns are dominant. For 1991, the best global estimate i
