Contributions of Biotechnology in Agriculture Combating Climatic Variations

Climatic change has an enormous effect on economy which eventually depends upon the agricultural practices of any densely populated developing country. Human activities has produced global warming, disturbed the agricultural ecology for crop production challenging food security through salinity, adverse temperature, arid and saline soil condition and affected water precipitation leading to enhanced water use demand, dry land and hunger problems. Here we summarize the contribution of conservative and contemporary approaches of biotechnology involved in negative regulation of climatic fluctuations and their consequences by utilization of energy-efficient farming, plant tissue culture techniques and formulation of bio fertilizers, carbon sequestration with breeding for adaptive varieties, development of genetically advanced stress tolerant transgenic crops contributing in improved food security.
