Climate change is one of the most defining concerns of today’s world and has greatly reshaped or in process of altering earth’s ecosystems. Although climate change has been a constant process on earth, but in recent times, approximately last 100 years or so, the pace of this variation has increased manifolds. Due to the anthropogenic activities the average temperature has risen by 0.9 °C since nineteenth century, mainly due to greenhouse gas (GHG) emissions in the atmosphere. As per estimates this rise is expected to be 1.5 °C by 2050 or may be even more, the way deforestation is occurring, GHG emission is increasing and soil, water bodies and air are being polluted. The unprecedented hike in temperature has resulted in increased events of droughts, floods, irregular patterns of precipitation, heat waves and other extreme happenings throughout the globe.
The increasing demand of food due to ever growing population have resulted in intensive agricultural practices including unprecedented use of agro-chemicals, livestock generation (for meat and other source of income), exploitation of water resources etc. Forests act as a sink to the increasing amount of CO2 but unchecked rate of deforestation (mainly for development and agriculture) have imbalanced the natural process of carbon cycle. This has increased the amount of carbon footprint and induced uneven pattern of climate resulting in a variety of adverse effects which have major impact on agricultural production.
Climate change is resulting into a very high rate of land degradation causing enhanced desertification and nutrient deficient soils. The menace of land degradation is increasing by the day and has been characterized as a major global threat.Climate smart agriculture is also an important requirement for enhancing the yields and quality of production. Climate change and agriculture are strongly co-related.
It is clear that the fast pace of climate change will have far-reaching impacts on agro-ecosystems and their productivity. Hence it is high time that we prepare ourselves for the upcoming challenges so as to combat the impact of climate change and ensure food security not only for humans but other living beings as well. It is also the endeavor of the journal “Environmental Sustainability” to report green strategies to combat climate change and enhance agri-production through sustainable methods.
