Lets together make earth a better and ‘greener’ place to live in: Happy Earth Day

“Man is a complex being; he makes deserts bloom – lakes die”
-Gill stern

“Earth day” celebrated on 22nd of April every year, traces back its origin in the late 20th Century, where people from different Professional Backgrounds joined by the same motive took to the streets of America to tell the world about the need to conserve the Environment we live in. Gaylord Nelson, whose brainchild Earth day was, served the United States as a Senator and governor. The movement led to the formation of different environmental laws in the country. Thereafter most of the countries started celebrating this day.

Shocking statistics about deforestation, global warming, and other environmental issues have now become a part of the everyday news. Education and awareness, have done their part and now it’s time to act. The human race, the only species that have a great control over its surroundings have destroyed the environment to such a level where it can’t be revived unaided. Conservation and deterioration both are in our hands, It’s just the matter of choice.

Maps, being one of the best ways to present information and extent of deterioration in a large spatial scale understandable to the public, Aapah innovations, specialized in remote sensing is capable of preparing the maps with the help of Satellite data.

Aapah innovations salute Gaylord Nelson and all others who have worked to make Earth a better place to live in.

Less soil moisture in Madhya Pradesh: A matter of concern for Farmers

Madhya Pradesh, a state enriched with black cotton soil enjoys diverse climatic and soil conditions suitable for a broad range of agricultural products.1. Evaluating soil moisture conditions before sowing of Kharif crops(June and July) is of utmost importance as agriculture forms the backbone of the State’s Economy.It is clearly evident from the map shown above that the Soil moisture is less in the northern parts of the state compared to other parts which can be a matter of concern for the farmers

The image shows the soil moisture map for Madhya Pradesh state for 09-Mar-2018. The map is prepared by merging data from multiple satellites using the vikleda algorithm.
Some of the applications where soil moisture is useful are:

  • Optimal irrigation in farms
  • Identify areas being over-irrigated
  • Improved flood risk estimation
  • Monitor agricultural drought in near real time
  • Improved weather forecast
  • Analyse the impact of an irrigation project
  • Identify the irrigated area by an irrigation source
  • Automatic billing of farm based on the actual irrigation
  • Estimation of actual evapotranspiration taking place
  • Estimation of area getting degraded

Meteorological drought in Kerala: Indignation of Rain gods?

Kerala, the state blessed which was always been blessed with rain have been experiencing meteorological drought continuously for many years.The soil moisture map for the state as on 14th March 2018 reveals much about the condition.The districts of Palakkad and Malappuram like the previous years are experiencing less soil moisture, which if not controlled by water harvesting measures or any other means would turn into a drought which in turn leads to a shortage in drinking water as most of the population depends on groundwater.

Crop yield estimation during monsoon season using satellite remote sensing

The crop yield estimation allows the better management of crop for various purposes. The conventional method of crop yield estimation is the field based which is very costly in time and money and may incur large error in the estimation due to the incomplete ground observations. The satellite remote sensing allows for the coverage of all fields in a short span of time.

Vegetation indices e.g. NDVI, EVI are used for the crop yield estimation. Though these indices provide higher resolution data, sometimes it is very difficult to obtain cloud-free images. These indices are based on the optical data which is incapable of penetrating cloud and hence these indices are not useful during Kharif season when clouds are prevalent in India. Above figure shows the average monthly cloud condition over entire India1. As can be seen from the figure, most of the India is almost invisible during Kharif season.

Microwave sensor based satellite remote sensing is better suited for acquiring images under any weather conditions like cloud cover, rain, snow etc. and it also provides higher spatial resolution images. Aapah Innovations created a model for soybean crop yield prediction using time series of remote sensing satellite data from 2008 to 2014 for different districts of Telangana state. The model was developed using the advanced statistical tool i.e. copula probabilistic method. The copulas allow the estimation of the uncertainty also in the estimate. As an example, the below figure shows the estimated soybean crop yield along with the uncertainty in the estimate and observed data in Nizamabad district. The model is able to estimate the crop yield quite well with percent Mean Absolute Error being just around 1%.

Estimated and observed yield of soybean in Nizamabad district.

The model can be used to monitor the growth of crop in near real and time and simulate the likely crop yield. To know more about the model, contact Aapah Innovations.

Less soil moisture: Agrarian economy of Jharkhand at distress?

Jharkhand, the state covered with lush green forest has 80% of its rural population earning their primary income from Agriculture. The state practices mono-crop system (Kharif crops), mainly paddy and hence the yield mainly depends on soil moisture1. Soil moisture map of Jharkhand (as on 14th March 2017) shows less soil moisture in the northern part of the state, especially in districts – Giridih, Deoghar, Bokaro, Dhanbad etc whereas Godda, Sahibganji and Pakur shows good soil moisture. As June marks the beginning of the cropping season (sowing) in Jharkhand for Kharif crops, the decrease in soil moisture may be of great concern for the farmers. The problem should be addressed well before it worsens.
