Photochemical processing of organic aerosol at nearby continental sites: contrast between urban plumes and regional aerosol
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 3. Slowik J.G.; Brook J.; Chang R.Y.-W.; et al. - Copernicus GmbH, 2011As part of the BAQS-Met 2007 field campaign, Aerodyne time-of-flight aerosol mass spectrometers (ToF-AMS) were deployed at two sites in southwestern Ontario from 17 June to 11 July 2007. One instrument was located at Harrow, ON, a rural, agriculture-dominated area approximately 40 km southeast of the Detroit/Windsor/Windsor urban area and 5 km north of Lake Erie. The second instrument was located at Bear Creek, ON, a rural site approximately 70 km northeast of the Harrow site and 50 km east of Detroit/Windsor. Positive matrix factorization analysis of the combined organic mass spectral dataset ...

in Atmospheric Chemistry and Physics (ACP) > Vol. 11. N° 3 [03/01/2011] . - p.2991-3006As part of the BAQS-Met 2007 field campaign, Aerodyne time-of-flight aerosol mass spectrometers (ToF-AMS) were deployed at two sites in southwestern Ontario from 17 June to 11 July 2007. One instrument was located at Harrow, ON, a rural, agriculture-dominated area approximately 40 km southeast of the Detroit/Windsor/Windsor urban area and 5 km north of Lake Erie. The second instrument was located at Bear Creek, ON, a rural site approximately 70 km northeast of the Harrow site and 50 km east of Detroit/Windsor. Positive matrix factorization analysis of the combined organic mass spectral dataset yields factors related to secondary organic aerosol (SOA), direct emissions, and a factor tentatively attributed to the reactive uptake of isoprene and/or condensation of its early generation reaction products. This is the first application of PMF to simultaneous AMS measurements at different sites, an approach which allows for self-consistent, direct comparison of the datasets. Case studies are utilized to investigate processing of SOA from (1) fresh emissions from Detroit/Windsor and (2) regional aerosol during periods of inter-site flow. A strong correlation is observed between SOA/excess CO and photochemical age as represented by the NOx/NOy ratio for Detroit/Windsor outflow. Although this correlation is not evident for more aged air, measurements at the two sites during inter-site transport nevertheless show evidence of continued atmospheric processing by SOA production. However, the rate of SOA production decreases with airmass age from an initial value of ~10.1 μg m−3 ppmvCO−1 h−1 for the first ~10 h of plume processing to near-zero in an aged airmass (i.e. after several days). The initial SOA production rate is comparable to the observed rate in Mexico City over similar timescales.

UNSustainable
Global Change magazine, Issue 76. IGBP, 2011The United Nations has struggled to deliver on many environmental and developmental challenges. Time for new thinking, then, which is why UN Secretary-General Ban Ki-moon has set up the Global Sustainability Panel. But how can science contribute? Owen Gaffney discusses the panel with Janos Pasztor.

Towards a Green Economy: pathways to sustainable and poverty eradication (water chapter)
UNEP, 2011This chapter has three broad aims. First, it highlights the need for providing all households with sufficient and affordable access to clean water supplies as well as adequate sanitation. Second, it makes a case for early investment in water management and infrastructure, including ecological infrastructure. The potential to make greater use of biodiversity and ecosystem services in reducing water treatment costs and increasing productivity is emphasised. Third, the chapter provides guidance on the suite of governance arrangements and policy reforms, which, if implemented, can sustain and incr ...

Towards a Green Economy: pathways to sustainable and poverty eradication (a synthesis for policy makers)
UNEP, 2011UNEP’s Green Economy Report, entitled Towards a Green Economy, aims to debunk several myths and misconceptions about the economics of “greening” the global economy, and provides timely and practical guidance to policy makers on what reforms they need to unlock the productive and employment potential of a green economy.

L’agroécologie en pratiques
Agrisud International, 2010L’agroécologie consiste pour le paysan à chercher à imiter la nature dans son champ. Elle mise sur les complémentarités entre différentes plantes et animaux. Elle conçoit l’agriculture non comme un processus qui transforme des intrants en productions agricoles, mais comme un cycle, où le déchet sert d’intrant, où les animaux et les légumineuses fertilisent les sols et où les mauvaises herbes sont considérées comme remplissant des fonctions utiles.
