Integrated water management program : Integrated water management program is beneficial in addressing land degradation and water conservation in the rain-fed areas of the state. The satellite estimated soil moisture of the area can assess the impact of the program in the field of Agriculture. Soil moisture evaluated over years can help to assess the impact of the implemented water resources project. As the soil moisture is evaluated over a large time span extreme events won’t affect the results. Estimates of evapotranspiration can be used to quantify crop water productivity the number of marketable crops (for example, kilograms of grain) produced per cubic meter of water consumed to grow that crop.
Prediction of Floods: The flood depends upon the intensity of rainfall and the infiltration (absorption) capacity of soil which in turn is related to soil moisture. The satellite soil moisture provides information about the infiltration capacity of the soil. Combining near real-time precipitation data and satellite estimated soil moisture data can predict flash floods well before its occurrence and government and other decision making agencies can issue a warning every 24 hours and thus can reduce the losses due to floods. Flood extent mapping at Satyukt Analytics is performed with a latency of 24 hours.
Drought: Deficit in the available soil moisture can be monitored and drought can be predicted in near real time. Microwave satellites provide soil moisture and other ago- hydrological parameters at a high resolution in near real time. Microwave satellite provides information about the available soil moisture in near real-time which is useful for drought early warning. microwave data is advantageous during Kharif season as it has the capability of penetrating clouds.
Satyukt Analytics has the capability to monitor drought over SAARC region using a combination of active and passive microwave satellites in near real time. The near real-time soil moisture data can be helpful for government and other decision making agencies to manage the crisis.
Earth’s climate has changed throughout the history. The climate is changing drastically now than at any point in history, mainly because of the anthropogenic activities12. Living and coping the impacts of the most debated issue of climate change is no longer a choice but is essential for the survival. Climate change is growing as a global concern because it affects most sectors and prominently agriculture. As agriculture forms the backbone of the Indian economy, climate change analysis over the agriculture sector helps to tackle the unprecedented challenges posed by changing climate.
Understanding climate change is the key to cope up with it. Climate change induced by both hydrologic and anthropogenic activities alters the Earth’s energy and water budget, near-surface climate, agro hydrological parameters, and many other parameters. Hence modeling agro-hydrological variables such as soil moisture, evapotranspiration, vegetation indices etc in near real-time can be beneficial to model climate changes and foretell extreme events. Agro hydrological variables due to its inherent memory can “remember” extreme climatic events long after the conditions responsible for the anomaly is forgotten by the atmosphere, is a key aspect of land-atmosphere interactions and hence can predict climate changes.
