This new study of nine coastal cities around the world published in the latest edition of journal Natural Hazards, says that Kolkata is among the most flood vulnerable cities in world and could experience coastal flooding as the city is built on river delta.

Increasing population size and per capita impacts are making sustainability a difficult to goal to achieve; this Review explores possibilities for sustainable development.

Localized ecological systems are known to shift abruptly and irreversibly from one state to another when they are forced across critical thresholds. Here we review evidence that the global ecosystem as a whole can react in the same way and is approaching a planetary-scale critical transition as a result of human influence. The plausibility of a planetary-scale ‘tipping point’ highlights the need to improve biological forecasting by detecting early warning signs of critical transitions on global as well as local scales, and by detecting feedbacks that promote such transitions.

Population has started to swell in Delhi’s suburbs. Gurgaon and Noida (Gautam Buddha Nagar) are among the top five places in India that recorded the highest decadal growth rate in population.

Climate change is projected to cause substantial increases in population movement in coming decades. Previous research has considered the likely causal influences and magnitude of such movements and the risks to national and international security. There has been little research on the consequences of climate-related migration and the health of people who move.

This paper analyzes the dynamics of population growth and urban expansion in the city of Xalapa, Mexico. It focuses on the establishment of informal settlements, which are one of the many threats to forest and farmland conservation (although these settlements are not the only source of the problem). Spatial analysis of growth data (using Geographical Information Systems (GIS) and statistical modelling) showed that by 2007, 90 per cent of the land area in the municipality of Xalapa had already been altered by human activity.
