Climate Change: Threat to Our Planet, Ways to ahead for Food Security



Climate change is of ultimate concern to economists, ecologists, and agriculturalists as agriculture and
climate change closely relate. While farmers have to amend their practices suffering from weather changes,the impact of modern agriculture on climate change cannot be denied. Thus, the connection between industrial agriculture and climate change demands keen attention as the influence is far from beneficial.

The accelerating pace of climate change, combined with global population and income growth, threatens food security and agriculture everywhere. Agriculture is extremely vulnerable to climate change. Higher temperatures eventually reduce yields of desirable crops while encouraging weed and pest proliferation. Pest’s management become less effective, heat waves can cause extreme heat stress in crops, which can limit yields.

If we look at 2021 monsoon, we witnessed erratic and extreme rainfall events. July & August were unusually dry threatening early stages of crop growth followed by unusually wet September causing flash floods in many areas causing widespread damage to standing crops. Intra monsoon precipitation variations caused by climate change is here to stay and will continue to cause disruptions in Indian agriculture.

On the other hand, there has been proliferation of technologies in agriculture with new high yielding, specially bred crop verities requiring precision farming with some very high degree of attention in the cultivation practices. Precision farming is variety-specific, site-specific soil specific as well as weather specific farm management concept that uses information technology to ensure optimum health and productivity of crops. It incorporates a broad range of technologies such as bioengineering, robotics and automation, imagery and sensors, and big data etc. Farmers are required to be ever alert to adapt quickly to the changing conditions of weather and climate.

Since June this year, Maharashtra has received 1,129.3 mm of rainfall, significantly above the average of 1,036.3 mm it usually receives in this period. This has created havoc in 10 districts in the state’s western and northeastern regions. As of this time, about 1.23 lakh hectares of kharif crop have been destroyed. The damage to crops amounts to about one per cent of the state’s total kharif crop, planted on about 141.98 lakh hectares.

In the current scenario, India’s agriculture is extremely vulnerable to climate change. Country needs crop diversification, productive water usage, development of extreme weather resistance crops and development in precision farming techniques.

BKC’s in-house instrumentation for precision farming as well as a weather-based decision support system that can auto-generate advisories and customizable bulletins.

  • metGIS is a measure tool that display the AWS data (Temp, RH, Wind, Pressure, Cloud cover or sunshine, radiation, ET, Soil Moisture, Soil Temp, etc.), NWP models, satellite images together or separately in layers in WMO defined formats. 
  • Crop Calendars and an interface and library of algorithms for crop and disease forecasting.  
 In India there is additional challenge of small holdings and highly fragmented agriculture. 

Fortunately, technologies now exist to address the new challenges in precision farming to make farming weather resilient irrespective of the farm size or the crop diversities.

कृषि क्षेत्र मे महिलाओं का योगदान

  आज महिलाएं हर जगह हर क्षेत्र में अव्वल स्थान पर है चाहे वो घर का काम हो या बाहर का काम वह दोनों चीजों में सामंजस्य बैठा के आगे बढ़ रही है और हर चीज़ को अच्छे से संभाल रही है। वह पुरुषों के साथ कदम से कदम मिलाकर चल रही है ऐसा कोई क्षेत्र नहीं जहाँ उन्होंने अपना नाम रोशन न किया हो। बात की जाए कृषि क्षेत्र की , कृषि क्षेत्र में जितना योगदान पुरुषों का है उतना ही योगदान महिलाओं का भी है ।   भारत की लगभग 70 फीसदी आबादी ग्रामीण इलाकों में रहती है जिनके आय का जरिया खेती से ही निकलता है। घरेलू कार्य के साथ साथ वह खेत का सारा कार्य अच्छे से संभालती है। अनेक कार्य जैसे पौधों को रोपना , बीज लगाना फसलों की कटाई आदि कामों में वह निपुण हैं साथ ही साथ अन्य कार्य जैसे पशुपालन , मुर्गी पालन , मधुमक्खी पालन आदि को भी वे बड़ी बखूबी से निभाती हैं अन्य कार्य जैसे दूध घी एवं दही बनाना , आचार एवं चटनी , पापड़ आदि बनाने से वह आमदनी अंकित कमाती हैं और घर संभालती हैं। आज के समय में वह नई तकनीकों को सीखकर अच्छा पैसा और काम दोनों कमा रही हैं और अपना योगदान कृषि में बखूबी दे रही है । कृषि क्षेत्र में महिलाओ

Technology - Advising Farmers and Crop Yield Assesment

Food security in the light of climate change is a global imperative. In developing nations, the problem is exacerbated by variable weather, lack of reliable extension services to optimize yield and fair market access. In India, most farmers do not have access to weather advisory forecasts that are hyper local to their field and timely in nature. As all farming activities are heavily dependent on weather, decisions on application of fertilizers and pesticide, irrigation, and even plucking of fruits & vegetables and harvesting cannot be taken efficiently. In addition, significant crop losses, that are entirely preventable, accrue through adverse weather events. Crop advisory services, where available, are generic and not pegged to a farmer's seed variety, date of sowing, and growing conditions and hence do not dispense timely, actionable advice, directly relevant to a farmer. Likewise, market trends pertinent to their particular crop and location


India is poised to have a good monsoon this year. It can be seen for the NOAA graph of Fig. 1 below. El Nino conditions are changing to La Nina from May June July. Fig. 1: ENSO Probabilities by NOAA This year, the Southwest Monsoon is anticipated to arrive in extreme parts of South-SE Bay around the first week of May, gradually progressing northward. Seasonal Forecast as given by IRI in Fig. 2 below. Fig. 2: Seasonal Forecast by IRI Regional Outlook: The monsoon season may extend into early October this year. Western and Northwestern India: Above-normal to excess rainfall is possible over most parts of Western and Northwestern India, including Gujarat, Rajasthan, Punjab, Maharashtra, Telangana, Madhya Pradesh, and Chhattisgarh. This increased Rains is likely to raise concerns for potential flooding, especially during the peak and late monsoon seasons. Rains are likely to be favorable to all Kharif Crops.
