All four dimensions of great challenges of twenty-first century, particularly it is food security food production, trade, stability of food likely to affect agricultural ecosystems in many ways, but supplies, access to food and food utilization would be perhaps most notable is that it will affect different regions affected.
Climate change would add to the burden of of the globe differently. Tropical regions—and thus developing countries already faced with serious food developing countries—will generally be more severely insecurity problems and it would exacerbate them.
It affects Introduction not only all people on the planet, but also governs the future of the rest of the biosphere. Because so much, and so One of the most important challenges currently facing many, are at stake, the question of how to minimize and humanity is climate change and will continue to be a major deal with climate change remains hugely controversial.
It also presents a Densely populated developing countries in tropical and new threat because of the unexpected temperature and sea drought-stressed regions could experience increased food level rise.

These gases low-latitude countries are not backed by detailed and accumulate in the atmosphere, which results in global country specific studies, nor do they sufficiently factor in warming.
The changes in global climate related parameters potential adaptation measures. However, the implications are temperature, precipitation, soil moisture and sea level. However, the reliability of the predictions on climate change is uncertain. Climate change is a major challenge P. Agriculture is the sector most vulnerable to climate 3-Ravi Nagar, Peroorkada P.

Department of Agriculture. Farmer Demand for Agricultural Biotechnology Continues To Grow The modern American farmer is a savvy business person, and an increasing number of farmers are choosing to plant biotech seeds. Agricultural biotechnology delivers significant and tangible benefits for farmers including increased crop yields and lower input costs.
All four dimensions of great challenges of twenty-first century, particularly it is food security (food production, trade, stability of food likely to affect agricultural ecosystems in many ways, but supplies, access to food and food utilization) would be perhaps most notable is that it .
Biotechnology is the application of scientific and engineering principles to the processing of materials by biological agents to provide goods and services. From its inception, biotechnology has maintained a close relationship with society. Although now most often associated with the development of drugs, historically biotechnology has been principally associated with food, addressing such.
