Impact of Climate change on Agriculture Output
Agriculture is an economic activity which is highly reliant on climate and weather in order to produce the food and fiber necessary to sustain human life. Agriculture is, however, an activity which is extremely vulnerable to climate change.
Due to global warming, the temperature has increased twice during the last 50 years.
The mean temperature in India is protected to increase up to 1.7ºC in Kharif season (July to October) and up to 3.2ºC during the rabi season(November to March), while the rainfall is expected to increase by 10% by 2070.
Global warming influences the occurrence and severity of plant pest and disease attack. Due to this, the interaction between crop and pathogens is affected in multiple ways, which has an adverse effect on managing them with regard to timing, preference, and efficacy of chemical, physical and biological measures. This in turn leads to a severe threat to global crop production and results in a yield loss of up to 10–25%.
A major example of the devastating effect of climate change is floods and drought. During floods, a rise in sea level results in the disappearance of low-level lands causing major crop losses.
During drought, the insufficient water level in the soil causes plants to lose their biological functions and even become more susceptible to disease and pests. Climatic conditions contribute to the disease triangle, which involves the presence of suitable host pathogens and suitable environmental conditions for infection to occur and climate change affects environmental conditions whether it be in favor of the host or the pathogen. Examples of these conditions include dew, rain, relative humidity, temperature, aeration(wind), soil moisture, and sunlight intensity.
Prediction of future disease and pest management requirements is of great importance for agro-industries, extension services, and practical farmers.
Satyukt Analytics Pvt Ltd, an initiative by a pool of multidisciplinary technical professionals teamed up to deliver earth observation data. It has developed innovative solutions in the field of agriculture and water resources by using optical and microwave remote sensing and has developed innovative mathematical models which in comparison to the traditional ones are far superior both in terms of accuracy as well as spatiotemporal resolution/frequency.
At Satyukt, we have developed a mobile app called Sat2Farm, where on successful upload of the farm by the farmer, we provide crop advisories including disease and pest, crop growth monitoring through (Normalized Difference Vegetation Index) NDVI, (Enhanced Vegetation Index) EVI, (Soil Moisture) SM data, Weather information like rainfall, wind, relative humidity temperature maximum and minimum. We also give early information of pest and disease attacks of particle crops based on weather data, so that farmers can have a close look at their farm and take necessary actions according to their crop health states.
