This study quantifies and maps the water footprint (WF) of humanity at a high spatial resolution. It reports on consumptive use of rainwater (green WF) and ground and surface water (blue WF) and volumes of water polluted (gray WF). Water footprints are estimated per nation from both a production and consumption perspective. International virtual water flows are estimated based on trade in agricultural and industrial commodities. The global annual average WF in the period 1996–2005 was 9,087 Gm3/y (74% green, 11% blue, 15% gray). Agricultural production contributes 92%.

It is evident that there have been some significant changes in the food consumption basket. The latest National Sample Survey data for 2009-10 (66th Round) show a further shift away from food to non-food items in all expenditure categories across both rural and urban areas. This analysis of changes across three rounds (1993-94, 2004-05 and 2009-10) reveals that the pace of change accelerated between 2004-05 and 2009-10.

Anaemia aff ects a quarter of the global population, including 293 million (47%) children younger than 5 years and
468 million (30%) non-pregnant women. In addition to anaemia’s adverse health consequences, the economic eff ect
of anaemia on human capital results in the loss of billions of dollars annually. In this paper, we review the
epidemiology, clinical assessment, pathophysiology, and consequences of anaemia in low-income and middleincome countries. Our analysis shows that anaemia is disproportionately concentrated in low socioeconomic groups,

We all know we need to eat less meat – here are the hard numbers.
