Global populations continue to urbanise at an unprecedented rate, with cities expanding into huge concentrations of concrete, steel, and glass, raising sustainability concerns. I’ve attempted to explore this issue from the standpoint of urban ecology, an interdisciplinary branch of study that looks at the complex interactions between the built environment of cities and non-human species.

While Ojit was observing the mating behaviour of dragonflies, I was extremely fascinated with the eyes of the insect. And so, I inquired about vision in insects.

Ajay Immanuel Gonji Every year, during the monsoon season, the Dheerpur Wetland Project (DWP) site undergoes a drastic transformation in its appearance. Torrential rains and stormwater flowing into the wetland from surrounding areas lead to flooding in most parts of the wetland. During this time, the DWP site also serves as a habitat for a…
Amit Kaushik This present piece is a photo blog depicting some of the bird species that have been sighted at the Dheerpur Wetland Park (DWP) during the bird surveys undertaken by the Centre for Urban Ecology and Sustainability (CUES) over the past several months. In the face of rapid urbanization in Delhi, spaces such as…
Vipin Kumar The mineral and nutrient-rich uppermost layer of the earth’s crust that supports almost all lifeforms in the terrestrial environment is known as soil. It is formed by the slow and continuous weathering of rocks by various physical (thunderstorm & cracks by water freeze), chemical (atmospheric chemicals) and biological (plants & microbial growth) factors.…
Amit Kaushik Soils are known to have enormous seed banks and there are some long-lived seeds which patiently wait to sprout until the seed dormancy period has passed. However, in an area where wetlands have been drained and cultivated for more than 10-15 years, seeds in the seed bank die and may not be able…

However, when the first rains of the season did arrive, we were slightly unprepared for plantation. To begin with, we did not have…
