What is Biotechnology
The UN Convention on Biological Diversity states, “Biotechnology is any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use”. The OECD (the Organization of Economic Co-operation and Development) defines biotechnology as “…the application of scientific and engineering principles to the processing of materials by biological agents”. Thus, “Biotechnology” basically means using biology as the basis for a technology that is applied to research and product development in areas such as agriculture, food science, and medicine.
The Academic Standards for Science and Technology defines Biotechnology as the ways that humans apply biological concepts to produce products and provide services. This is very true if we consider a section of biotechnology in which the directed manipulation of organisms is used for the product of organic products such as beer, milk products, food etc.
Biotechnology had already been performed long before the term itself was coined, though on a very basic level. For example, man had already learnt the method of fermenting fruit juices to concoct alcoholic beverages during the period around 6000 BC. However, it was considered more of an art then. Biotechnology became a real science only about two decades ago when genes were found to contain information that would enable the synthesis of specific proteins. This was in the 1970s, when new advances in the field of molecular biology enabled scientists to easily transfer DNA – the chemical building blocks that specify the characteristics of living organisms – between more distantly related organisms.

The Benefits Of Agricultural Biotechnology
Agricultural biotechnology is any technique in which living organisms, or parts of organisms are altered to make or modify agricultural products, to improve crops, or develop microbes for specific uses in agricultural processes. Simply put, when the tools of biotechnology are applied to agriculture, it is termed as “agricultural biotechnology”. Genetic engineering is also a part of agricultural biotechnology in today’s world. It is now possible to carry out genetic manipulation and transformation on almost all plant species, including all the world’s major crops.
Plant transformation is one of the tools involved in agricultural biotechnology, in which genes are inserted into the genetic structure or genome of plants. The two most common methods of plant transformation are Agrobacterium Transformation – methods that use the naturally occurring bacterium; and Biolistic Transformation – involving the use of mechanical means. Using any of these methods the preferred gene is inserted into a plant genome and traditional breeding method followed to transfer the new trait into different varieties of crops.
Production of food crops has become much cheaper and convenient with the introduction of agricultural biotechnology. Specific herbicide tolerant crops have been engineered which makes weed control manageable and more efficient. Pest control has also become more reliable and effective, eliminating the need for synthetic pesticides as crops resistant to certain diseases and insect pests have also been engineered. Phytoremediation is the process in which plants detoxify pollutants in the soil, or absorb and accumulate polluting substances out of the soil. Several crops have now been genetically engineered for this purpose for safe harvest and disposal, and improvement of soil quality.
