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.

UFS and Mexico forge links
The Centre for Plant Health Management (CePHMa) in the Department of Plant Sciences at the University of the Free State (UFS) is presenting its first international conference.  The conference started yesterday and will run until tomorrow (Friday 31 March 2006) on the Main Campus in Bloemfontein. 

The conference is the first on cactus pear (or prickly pear) in South Africa since 1995.  It coincides with 2006 being declared as International Year of Deserts and Desertification by the United Nations General Assembly. 

During the opening session of the conference yesterday a memorandum of understanding (MOU) was signed between CePHMa and the University of Chapingo (Universidad Autonoma Chapingo) in Mexico.  The signing ceremony was attended by the Ambassador of Mexico in Southern Africa, His Excellency Mauricio de Maria y Campos, the Rector of the University of Chapingo, Dr José Sergio Barrales Domínguez, and the Vice-Rector: Academic Planning of the UFS, Prof Magda Fourie, amongst other important dignitaries. 

“South Africa and Mexico have a lot in common where agricultural practices in semi-arid areas and the role of the cactus pear are concerned,” said Prof Wijnand Swart, Chairperson of CePHMa at the opening of the conference.

He said that the MOU is the result of negotiations between CePHMa and the Ambassador of Mexico in Southern Africa over the past 12 months.

“The MOU facilitates the negotiation of international cooperative academic initiatives between the two institutions.  This entails the exchange of students and staff members of the UFS, curriculum development, research and community service,” said Prof Swart.

“During the next two days, various areas of interest will be discussed.  This includes perspectives from commercial cactus pear farmers in South Africa, the health management of cactus pear orchards, selection of new cultivars of cactus pear, and the nutritional and medicinal value of the crop,” said Prof Swart.

In his welcoming message Prof Swart explained that in recent years there has been increased interest in the cactus pear for the important role it can play in sustainable agricultural systems in marginal areas of the world.  These plants have developed phenological and physiological adaptations to sustain their development in adverse environments. 

“The cactus pear can serve as a life saving crop to both humans and animals living in marginal regions by providing a highly digestible source of energy, water, minerals and protein,” said Prof Swart. 

“In an age when global warming and its negative impact on earth’s climate has become an everyday subject of discussion, the exploitation of salt and drought tolerant crops will undoubtedly have many socio-economic benefits to communities inhabiting semi-arid regions,” said Prof Swart.

“Plantations of cactus pear grown for fruit, forage and vegetable production, as well as for natural red dye produced from the cactus scale insect known as cochineal have, over the last two decades, been established in many countries in South America, Europe, Asia and Africa.  The crop and its products have not only become important in international markets, but also in local markets across the globe,” said Prof Swart. 

Detailed discussions on the implementation of the MOU will take place between CePHMa and the University of Chapingo after the conference.
