This paper is an overview of the issues surrounding India’s water scarcity, and also comparison of clean water standards
between developing and developed nations.

One of the vital activities in an urban area is transport. However it also contributes to air pollution, noise pollution and road traffic accidents. Congestion, vibration, community severance and visual intrusion are other transport related problems. Air quality on the city of Kolkata (a metro city of India) seems to be deteriorating. Pollution level in the city and its outskirts is alarming. This is due to old vehicle plying in the road of Kolkata and illegal vehicle plying violating pollution norms, by using bad fuel such as KATATEL.

Programmes to address global warming and promote green development, such as Payments for Ecosystem Services and Reduced Emissions from Deforestation and [forest] Degradation financed by carbon-offset trading, are framed by a world-as-market paradigm that subsumes social goals within a project of globalized eco-economic management. Because market-based strategies reinforce existing property claims and power relations, Kathleen McAfee argues that they are likely to worsen inequality without yielding net, global environmental benefits.

The temperature thresholds and timings of the 24 climatic Solar Terms in China are determined from a homogenized dataset of
the surface air temperature recorded at 549 meteorological stations for the period 1960–2008 employing the ensemble empirical
mode decomposition method. Changes in the mean temperature and timing of the climatic solar terms are illustrated. The results
show that in terms of the mean situation over China, the number of cold days such as those of Slight Cold and Great Cold has

Bhutan has achieved a major reduction in malaria incidence amid multiple challenges. This case study seeks to characterize the Bhutan malaria control programme over the last 10 years.

Current malaria elimination guidelines are based on the concept that malaria transmission becomes heterogeneous in the later phases of malaria elimination. In the pre-elimination and elimination phases, interventions have to be targeted to entire villages or towns with higher malaria incidence until only individual episodes of malaria remain and become the centre of attention. With increasing evidence of clustering of malaria episodes within villages, we argue that there is an intermediate step.

The vast majority of American middle schools and high schools sell what are known as ‘‘competitive foods,’’ such as soft drinks, candy bars, and chips, to children. The relationship between consumption of sugar-sweetened drinks and snacks and childhood obesity is well established, but it remains unknown whether competitive food sales in schools are related to unhealthy weight gain among children. The authors examined this association using data from the Early Childhood Longitudinal Study, Kindergarten
