Decarbonization Agriculture in India: Current State and Way Forward

India is the third-highest greenhouse gas (GHG) emitter behind China and the United States. India’s farm sector accounts for 14% of the country’s total greenhouse gas emissions , preceded by electricity (44%) and the construction sector (18%).  GHG Emissions Caused by the Agriculture Sector in India Indian rice fields and their substantial livestock population are the primary causes of methane release. India has the largest population of bovine animals (cattle and buffalo) at 625 million heads . 54.6 per cent of GHG emissions were due to enteric fermentation and 6.7 per cent from poor manure management. India is the world’s largest rice producer by area, estimated at 44.0 million hectares. This constitutes about 7.5 per cent of GHG emissions.  Current status of Sustainable Agricultural Practices in India Agriculture is an important sector of the Indian economy, contributing about 20% of the national GDP . The changes in climatic events such as temperature, rainfall and atmospheric

Decarbonising Agriculture: Reducing Emissions Through Better Farm Practices

The agricultural sector contributes to more than one-quarter ( about 24% ) of the world’s GHG emissions. The IPCC report on the impacts of global warming clearly states that a “rapid and far-reaching” transition is required to limit the impact of climate change to 1.5 degrees. Achieving these goals can be more challenging for the agricultural sector than others as it requires the collective effort of more than two billion people who depend on farming for their survival. Alongside climate goals, it must contemplate nutrition needs, food security, and the livelihood of farmers and farming communities. Major sources of GHG emissions in agriculture are: Methane emissions - Agricultural emissions are primarily the result of ruminant animals (principally cows and sheep), farming practices, and rice production. Ruminants create methane during digestion, along with CO2 and other gases. The impact is significant: ruminants account for almost 70 per cent of agricultural emissions . They are re

Micro and Meso Weather Monitoring in Vineyards

On a bottle of wine, you normally see a year imprinted on its label. That represents the ‘vintage’, the year that its grapes were picked. But how is this information important? And what makes one vintage better than another? Answer - the weather. It is one of, if not the most important external factor for the calibre of wine produced. The weather in the vineyard during a given year impacts the health and quality of the fruit produced. In viticulture practices, winegrowers need to precisely focus on weather conditions surrounding their vineyard , technically termed ‘meso-weather’, and more precisely the environment within the vineyard canopy (such as rows of vines), called the ‘micro-weather’, as opposed to the weather details of a larger area as determined by any local weather station ‘macro-weather’.  Micro-level variables can be considerably different ( up to 37% ) from that of the macro-level region. One of them is the Soil moisture Content which is specific to the plots. Water stre

Nagpur Orange Belt and Shortage of Water - How Smart Irrigation Can Help?

Shridhar Thakre, owner of a 20-acre land with 3,500 orange trees in Talegaon village (Ashti) in Wardha district, reportedly stopped going to the orchards as he could not see the condition of the trees. “The temperatures continuously hovered between 44 - 47.5 degrees celsius in the month of May, for the first time. Pre-monsoon showers were absent too” said Thakre to the Times of India. This condition resides with hundreds of orange farmers in Nagpur, home to the most important commercial citrus cultivation in the country occupying around 0.2 million hectares of Satpura hills (Vidarbha region) of Central India.  Citrus crops are high water requiring evergreen perennial fruit crops. About sixty-eight per cent of citrus growers prefer basin irrigation. The orange orchards are irrigated majorly by the basin method using groundwater in this region. Rainfall data in the Nagpur region for the past 100 years show a declining trend. Groundwater levels are declining in most parts not only
