Love lingers in the air this week and red hearts adorn our desks but there’s an even more coveted symbol of affection to watch out for from today; the Green Heart.

The organisers of South Africa’s Green Office Week initiative have launched a brand new award to recognise and reward those workplace eco-champions who have given their hearts to the whole planet: The Green Heart Award.

The award aims to bring "going green" into the mainstream by creating rolemodels in South African workplaces and recognising those who have made a significant contribution to going green by finding creative and interesting ways to improve their department, office, dorm, or building’s environmental footprint.

Green Heart spokesperson Ana-Maria Valente says: “We are witnessing a dramatic reorientation of the global economy around the principles of sustainability.

While the South African government decides whether or not to let fracking loose in SA, the state of Ohio in the US is trying to escape the effects of the technology. “Ohio has become the dumping ground for contaminated brine. We didn’t prepare adequately for the potential for earthquakes and other environmental problems”; – this was the view of state Representative Armond Budish, the House Democratic leader in Columbus, at a forum in the state capital, Columbus on January 26.

Ohio, labelled, ‘Pennsylvania’s (PA) Sponge’, absorbed 368.3 million gallons [of toxic frackwater] during last year’s first three quarters, according to Natural Resources Department records. That’s more than in any year since 1987, records show. Nearly 99% of all fracking wastewater from PA Marcellus shale operators sent to disposal wells in the first six months of 2011, went to Ohio.

Large-scale construction is in full swing at the V&A Waterfront as the R1-billion transformation of the Clock Tower Precinct into a premier 'lifestyle destination' is taking shape.

Given the historical and natural significance of its positioning, the redevelopment of the Clock Tower Precinct – and in particular the construction of No 1 Silo – is guided by the latest global requirements for environmentally sustainable construction, as governed by the Green Building Council of South Africa.

“Sustainable development is regarded as a fundamental aspect of the V&A Waterfront’s overall development strategy,” says David Green, CEO of the V&A Waterfront. “We have therefore adopted a rigorous approach to green construction and sustainable design principles, and the efficient use of natural and energy resources,” he says.

For three weeks in July 2012, Greenpop is hosting a reforestation project in Livingstone, Zambia; the country with the second highest deforestation rate in the world. We will plant over 5000 indigenous and fruit trees that are growing at the Zambezi Nkuku nursery, and host valuable educational sessions for children and subsistence farmers. This will be the start of an ongoing campaign to make Zambia a greener and more sustainable place.

Intaka Island WetlandIn celebration of World Wetlands Day, the City of Cape Town will be hosting various wetland education programmes as part of its Youth Environmental School (YES) programme during February 2012.

World Wetlands Day is held every year on 2 February and marks the signing of the International Convention on Wetlands of International Importance (the Ramsar Convention) on 2 February 1971. World Wetlands Day was celebrated for the first time in 1997 and since then, events and activities are held world-wide in February each year to raise awareness of wetland values and benefits. Ramsar is celebrating its 40th anniversary this year.

To date, the City of Cape Town has set aside over

Hartmut Jagau with the generator he designed using magnets from discarded hard drivesThe design for a sustainable wind generator using redundant materials has earned a prestigious international award for Hartmut Jagau, a master’s student in electrical engineering at the University of Cape Town.

Jagau won the Student Poster Presentation award at the 2011 Institute of Electrical and Electronics Engineers’ Energy Conversion Congress & Exposition that was held in Phoenix, Arizona, USA, in September 2011.

City Sightseeing Cape Town, the company that operates the well-known red double decker open-top buses has become the first bus company in South Africa to be certified carbon neutral.

City Sightseeing operate a fleet of continually upgraded, low emission buses that comply with all Euro standards for environmental impact. The fleet has consistently complied with Euro standards since 2006.

City Sightseeing has also made great inroads into greening the rest of the business and has adopted all the latest available methodology and technology to reduce noise pollution as well as energy and water consumption. The company also recycles all of their waste, which has in turn led to the creation of sustainable employment.

The new report, Health co-benefits of climate change mitigation - Transport sector was released 6 December, 2011 during the United Nations Framework on Climate Change Conference of the Parties (COP-17).

The report reviewed over 300 studies on health outcomes from different types of land transport systems to identify those mitigation measures most closely associated with specific health co-benefits or risks.

The review is the latest product of

Climate-smart agriculture must target the short-term needs of the smallholder farmer to be effective in combating climate change.

Encouraging climate-smart agriculture can lead to climate change adaptation practices in a partnership where the farmer’s needs are addressed.

“Climate-smart agriculture has the potential to increase sustainable productivity, increase the resilience of farming systems to climate impacts and mitigate climate change through greenhouse gas emission reductions and carbon sequestration,” says Henry Neufeldt the lead expert on climate change at the World Agroforestry Centre (ICRAF).

Agroforestry and its benefits

Agroforestry – the growing of trees on farms – is one such climate-smart agricultural practice, and it has tremendous potential for both
