Air pollution not only costs lives, it costs money too. Pictured is Prof Cathryn Tonne presenting a guest lecture on air pollution at the Bloemfontein Campus.

Health effects associated with ambient air pollution (AAP) have been well documented. Subsequently, the relationship between pollution and financial outcomes have also become a focus for case studies globally. An Environmental Research journal article revealed that “low and middle-income countries are disproportionately affected by the global burden of adverse health effects caused by AAP”. 

A high price to pay

In 2012, high concentrations of air pollution caused 7.4% of all deaths, costing South Africa up to 6% of its Gross Domestic Product. According to the recent International Growth Centre study conducted by senior University of Cape Town researchers, this is a direct consequence of the country’s heavy dependence of fossil fuels, a source of health-damaging air pollution and greenhouse pollutants.

Stunted human and economic growth

These South African statistics are attested to by Prof Cathryn Tonne who recently presented a guest lecture on air pollution which was hosted by the University of the Free State (UFS) Business School.

“Air pollution can affect economic development through several pathways, and health is an important one. Air pollution is linked to shorter life expectancy, chronic disease, asthma exacerbation and many other health outcomes that result in absenteeism from work and school. These have large direct costs to the health system.” 

Prof Tonne says that air pollution exposure in children is linked to reduced cognitive development, with important impacts on human capital. As a result, children are not reaching their full potential in terms of neurodevelopment, which has an effect on their income prospects and the economy as a whole. 

Resolving a looming disaster

Technology may be employed to radically clean the air. Cities need to lead in the reduction of air pollution by promoting renewable energy, using active transport such as walking or cycling, and investing in infrastructure to make this safe and attractive. 

With researchers playing a major role in strengthening the case for aggressive air pollution control, the government needs to implement policies in order to control sources of air pollution. This global health and economic issue also requires individuals and communities to play their part to improve air quality.

Professor’s research part of major global programme
2011-04-04

 

Prof. Zakkie Pretorius, professor in Plant Pathology in the Department of Plant Sciences at our university

Research by Zakkie Pretorius, professor in Plant Pathology in the Department of Plant Sciences at our university, has become part of Phase II of a mayor global project to combat deadly strains of a wheat pathogen that poses a threat to global food security.

Prof. Pretorius focuses on the identification of resistance in wheat to the stem rust disease and will assist breeders and geneticists in the accurate phenotyping of international breeding lines and mapping populations. In addition, Prof. Pretorius will support scientists from Africa with critical skills development through training programmes. During Phase I, which ends in 2011, he was involved in pathogen surveillance in Southern Africa and South Asia.
 
The Department of International Development (DFID) in the United Kingdom and the Bill and Melinda Gates Foundation will invest $40 million over the next five years in the global project led by the Cornell University. The project is aimed at combating deadly strains of Ug99, an evolving wheat pathogen that is a dangerous threat to global food security, especially in the poorest nations. 
 
The Cornell University said in a statement, the grant made to the Durable Rust Resistance in Wheat (DRRW) project at Cornell will support efforts to identify new stem-rust resistant genes in wheat, improve surveillance, and multiply and distribute rust-resistant wheat seed to farmers and their families.
 
Researchers worldwide will be able to play an increasingly vital role in protecting wheat fields from dangerous new forms of stem rust, particularly in countries whose people can ill afford the economic impact of damage to this vital crop.
 
The Ug99 strain was discovered in Kenya in 1998, but are now also threatening major wheat-growing areas of Southern and Eastern Africa, the Central Asian Republics, the Caucasus, the Indian subcontinent, South America, Australia and North America.
 
Prof. Pretorius was responsible for the first description of this strain in 1999.
 
Among Cornell’s partners are national research centres in Kenya and Ethiopia, and scientists at two international agricultural research centres that focus on wheat, the Mexico-based International Maize and Wheat Improvement Center (known by its Spanish acronym as CIMMYT), and the International Center  for Agricultural Research in the Dry Areas (ICARDA), in Syria. Advanced research laboratories in the United States, Canada, China, Australia, Denmark and South Africa also collaborate on the project. The DRRW project now involves more than 20 leading universities and research institutes throughout the world, and scientists and farmers from more than 40 countries.
