To be able to curb the global pandemic of physical inactivity and the associated 5.3 million deaths per year, we need to understand the basic principles that govern physical activity. However, there is a lack of large-scale measurements of physical activity patterns across free-living populations worldwide. Here we leverage the wide usage of smartphones with built-in accelerometry to measure physical activity at the global scale. We study a dataset consisting of 68 million days of physical activity for 717,527 people, giving us a window into activity in 111 countries across the globe.

Previous studies indicate that the design of streets and sidewalks can influence physical activity among residents. Park features also influence park use and park-based physical activity. Although individuals can walk on streets and sidewalks, walking loops in parks offer a setting to walk in nature and to avoid interruptions from traffic. Here the researchers describe the use of walking loops in parks and compare the number of park users and their physical activity in urban neighborhood parks with and without walking loops.

An analysis of the factors which led to Delhi experiencing one of its worst smog episodes in recent years in November of 2016 has been documented in this report. The report suggests source wise action status and a detailed plan of action for Delhi to combat the worsening air quality in the city.

Lack of investment in safe walking and cycling infrastructure is contributing to the deaths of millions of people and overlooking a great opportunity to contribute to the fight against climate change, a new UN Environment report says.

Manhattan skyscrapers, rather than rustic rural towns, are quickly becoming the picture of sustainable living in the twenty-first century. San Francisco, Copenhagen and Singapore each top their regions in the Green City Index. As sites of innovation and economic dynamism, these places exemplify a blend of density and livability that large, prosperous cities in the 'global south', such as Mumbai in India and São Paulo in Brazil, increasingly emulate.

Prevalence of walking and cycling for transport is low and varies greatly across countries. Few studies have examined neighborhood perceptions related to walking and cycling for transport in different countries. Therefore, it is challenging to prioritize appropriate built-environment interventions. The aim of this study was to examine the strength and shape of the relationship between adults’ neighborhood perceptions and walking and cycling for transport across diverse environments.

The lack of road safety remains a major challenge in many urban areas, although high levels of road safety are a prerequisite for the attractiveness of cycling, walking and public transport. GIZ publishes the new publication “Towards more livable and safer cities: Examples for save safe road infrastructure design”.

As Delhi's odd-even scheme prepares to make a comeback in April 2016, India Environment Poratl takes a look at what modes of transport, if any, India uses to get to work.

A population-based propensity-score matched cohort study design was used based on the Ontario population from the Canadian Community Health Survey (2001-2010). Participants were adults aged 20 years or older who moved from a low walkability neighborhood (defined as any neighborhood with a Walk Score<90) to either a high (Walk Score≥90) or another low walkability neighborhood. The incidence of hypertension was assessed by linking the cohort to administrative health databases using a validated algorithm. Propensity-score matched Cox proportional hazard models were used.

Cities Safer by Design is a global reference guide to help cities save lives from traffic fatalities through improved street design and smart urban development. Over 1.2 million people die in traffic crashes globally, mostly pedestrians, and that number is growing every year.
