<p>Transport network models comprise of frameworks for the transportation infrastructure, and their development is based on a number of intrinsic contributory factors of which environmental features are a critical part. Transport network models are thus used as frameworks to formulate systems.</p>

<p>Although the effects are slow to be realized, with the IPCC predicting the possibility of a rise in global temperatures by 3 degrees Celsius by 2080 (Jones, 2017), the longer term effects with an increasing rate of acceleration in global atmospheric CO2 levels could have devastating effects on the Earth’s climatic patterns.</p>

<p>World wind types Ascertaining wind types is important to understand disaster&#8217;s. On May 30, 2017, a severe cyclonic storm ‘Mora’ crossed the Bangladesh coast in the forenoon, with a peak surface wind speed of 130 kmph (IMD, 2017).]</p>

<p>Demystifying ecosystem services Food chains in ecosystems exist in the form of food pyramids.

However, according to certain defining characteristics, certain levels of production and consumption can be differentiated in a food chain.</p>

<p>Forest fire monitoring from space is among the most sought after applications of satellite based remote sensing and is being used for decades. The Indian Space Research Organization (ISRO) has come up a long way in space technology and provides various earth resources monitoring services such as forest fire and agriculture residue burning monitoring.</p>

<p>Innovations in agricultural technologies and management have led to rapid agricultural development in many pockets of India. But this development, especially at the soil health level, has led to deficiencies especially in micro-nutrients that has affected the farm output. Soil Health Management (SHM) involves balanced nutrition levels in soil that are required for sustainable agricultural [&hellip;]</p>
