Sustainable Designs

Roca W +W W+W, which launched in the UK  inMarch 2010, combines two key elements of the bathroom to create an all-in-one washbasin and WC designed to maximize space and conserve water.  This ground breaking idea, incorporating Roca’s ‘water-reuse’ technology, uses waste water from the basin to fill the WC cistern, thereby reducing water usage by up to 25% compared to a standard 6/3 litre … Continue reading Sustainable Designs

Night soil as fertilizer

In North and Central Vietnam it is common among farmers to use excreta from the family double vault composting latrine (DVC) as fertilizer in the fields. The official Vietnamese health guidelines stipulate a six-month period of composting before applying excreta to two of their three annual crops. However, farmers in this region cannot afford to follow these guidelines and this paper presents the reasons why.In their efforts to ensure … Continue reading Night soil as fertilizer

The water footprint of humanity

Water footprints are estimated per nation from both a production and consumptionperspective. 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%. About one-fifth of the global WF relates to production for export. The total volume of international virtual water flows … Continue reading The water footprint of humanity

In a world where 2.5 billion people still do not have access to basic sanitation facilities, and 1.5 million children die each year from preventable diseases as a result, there is a pressing need to find sustainable solutions to this most ancient of human problems. “Nearly half of the population in developing regions – 2.5 billion – still lacks access to improved sanitation facilities. Shockingly, … Continue reading Nature’s call…

Perception of climate change

Source: PNAS Should the public be able to recognize that climate is changing, despite the notorious variability of weather and climate from day to day and year to year? We investigate how the probability of unusually warm seasons has changed in recent decades, with emphasis on summer, when changes are likely to have the greatest practical effects. We show that the odds of an unusually … Continue reading Perception of climate change

Climate Change, Health & Sustainability

Source: PNAS Climate change poses threats to human health, safety, and survival via weather extremes and climatic impacts on food yields, fresh water, infectious diseases, conflict, and displacement. Paradoxically, these risks to health are neither widely nor fully recognized. Historical experiences of diverse societies experiencing climatic changes, spanning multicentury to single-year duration, provide insights into population health vulnerability—even though most climatic changes were considerably less than those anticipated this century and beyond. … Continue reading Climate Change, Health & Sustainability
