The 3rd International Workshop on Cold-plasma and pulse power technologies for Food, Health and Agriculture (COFHA-2026) will be organized by NECTAR an autonomous institute under DST, GoI, in association with The Plasma Science Society of India (PSSI) during 14th-15th December 2026. This workshop will provide a common platform for interaction among scientists, engineers and young researchers working in the area of Cold Plasma Technologies particularly for food, health and agriculture. The two-days international workshop will consist of invited talks from expert scientists as well as presentations by participants in oral and poster sessions.
Recent years have seen a wide range of cutting edge uses for atmospheric pressure non-equilibrium cold plasmas and related pulse power technologies in the fields of biology, medicine, food, agriculture, and the environment. Such plasmas are capable of effectively eliminating spores and biofilms (which are typically very difficult to inactivate), as well as bacteria, yeasts, molds, and other hazardous microbes, including possible bioterrorism agents. The capacity to attain improved gas phase chemistry without the requirement for high gas temperatures is the most alluring aspect of these plasmas. Such plasmas exhibit electron energies much higher than that of the ions and the neutral species that remain near room temperature and the energetic electrons enter into the collision with the background gas, causing the enhanced level of dissociation, excitation, ionization, etc. Due to this fact, plasma does not cause any thermal damage to the objects it comes into contact with, and hence it is easy to use such plasmas for growing plants, preserving the quality, safety, and sustainability of food, as well as for bio-decontamination and sterilization of surfaces, water, air, food, and even living tissues without compromising them or having other negative effects. As a result, such cold plasmas have enormous potential for the food, agriculture, and health sectors. Several synergistic mechanisms, including as UV radiations, electric fields, charged particles, produced radicals, and reactive species, can be attributed to such plasma treatments.
Global efforts are being made to create newer technologies and comprehend the physical, chemical, and biological elements of cold plasma for use in agriculture, food, and health. More focused research and development is required. This international workshop will cover both substantial advancements in cold plasma technologies and cutting-edge research in fundamental plasma physics. The creation of a strategic planning document on cold-plasma technologies for food, health, and agriculture is anticipated at the conclusion of the workshop. A few awards will be given for the best oral and poster presentations in the workshop.

About Meghalaya
Meghalaya is located in the North-East of India and is a land of pristine landscapes and natural beauty. With an average annual rainfall of 1,150 cm, it is known for receiving the highest amount of rainfall in the country and within it, Mawsynram town being the wettest place on earth. Also famous for its living root bridges, virgin forests, breathtaking waterfalls, clear rivers and a network of caves, Meghalaya is popular on India’s tourism map. It has two National Parks and three Wildlife Sanctuaries and offers many adventure tourism opportunities like mountaineering, rock climbing, hiking and trekking, water sports, etc. Meghalaya is home to three indigenous tribes, the Khasis, the Jaintias and the Garos. The people of Meghalaya predominantly follow a matrilineal system where lineage and inheritance are passed through the daughters, particularly the youngest of the family and is one of the world’s largest surviving matrilineal cultures. The traditional religion is based on the belief of one supreme God or creator. Presently, most of the population has converted to Christianity, but the ancient traditions remain an integral part of lifestyle and culture.
