Remote sensing and GIS are promising tools for handling spatial and temporal data and help in integrating them for successful planning of natural resources. It is the science of measuring the earth using sensors mounted on high-flying aircrafts or satellites. These sensors collect data in the form of images and provide insights for manipulating, analysing and visualising those images. Since natural resources are not uniformly distributed and are spatially varied, it is challenging to capture the correct picture. Management of natural resources calls for scientific tools for timely and accurate dissemination of information. In natural resource management, remote sensing and GIS are mainly used in the mapping process. These techniques are useful in management of land, soil, coastal, watershed, urban and many more.

In India, the agriculture sector alone sustains the livelihood of around 50 percent of the population. Therefore, an increase in crop productivity has been a major concern. Since, the scope for increasing area under agriculture is limited, advanced crop production forecasting is required for better policymaking. Indian Space Research Agency (ISRO) and Indian Council of Agricultural Research (ICAR) successful experiment-Agricultural Resource Inventory and Survey Experiment (ARISE) used aerial colour photographs to estimate crop acreage in many states of India. Other Important uses of remote sensing include crop identification, stress detection, and crop yield modelling, drought monitoring, land degradation mapping and more. Urbanisation is important and inevitable for development, but its proper planning and management is crucial for sustenance. One of the important features of GIS is multilayered mapping. This kind of mapping helps municipal corporations, town planning boards to build cities that are better organised. The information systems with socio-economic data overlaid upon satellite data makes urban planning cost-effective and accurate. 

Coastal ecosystems have high ecological significance. GIS and remote sensing data are used to study coastal ecosystems and marine living resources which include habitats like mangroves, coral reefs and more. Apart from this, suspended shoreline dynamics can be studied and climatic changes leading to cyclones and sea level rise may be of special interest too. Geospatial data is effective in the analysis and determination of factors that affect the utilisation of these resources. The technologies provide a platform through which we can generate information that can be used to make sound decisions for sustainable development of the natural resources of India.

Q. In the given context of the passage, why are GIS and remote sensing tools crucial in the agriculture sector?

I.  This sector alone sustains the livelihood of around 50 percent of the population.
II. GIS and remote sensing would help in advanced crop production forecasting.
III. Drought monitoring can be done using GIS and remote sensing tools.
