Prof Chapagain  Inaugural
Prof Ashok Chapagain, Senior Professor in the Department of Agricultural Economics, recently delivered his inaugural lecture on the university’s Bloemfontein Campus. The title of his lecture was Counting Water: Simple yet Complex.

Virtually every economic sector, from agriculture, power generation, manufacturing, beverage, and apparel to tourism, relies on fresh water to sustain its business. Yet, water scarcity and water-pollution levels in river basins around the world are increasing due to growing populations, changing consumption patterns, and poor water governance.

These are the words of Prof Ashok Chapagain, Senior Professor in the Department of Agricultural Economics at the University of the Free State (UFS), who recently delivered his inaugural lecture on the university’s Bloemfontein Campus. The title of his lecture was Counting Water: Simple yet Complex.

He believes that in a world of increasing interconnectedness, equitable and sustainable resource management has become not only a local phenomenon, but also a global one. “The critical factors in managing these resources lie at both ends of the production and consumption chains. The interlinkages between agriculture, trade, economic, and energy policy and water-resources management must be understood,” he said.

Water footprint from farm to cup

The water footprint of a product is the volume of fresh water used to produce the product, measured over the various steps of the production chain. Water use is measured in terms of water volumes consumed or polluted, e.g. a cup of black coffee would take 140 litres of water as a result of water used in various processes, from the farm to the cup! 

Prof Chapagain said: “With the emergence of the water footprint concept, the public could for the first time see that the issue is not only related to direct water use in their houses, but also to their consumption of goods and services, such as food, fibre, and electricity. For example, a developed nation would typically state their water consumption data as around 100-200 litres per capita per day. This information is misleading, as it does not capture the massive amount of water needed to produce food, goods, and services consumed by the nation, which makes the daily water consumption a whopping 3 000-8 000 litres in these developed nations. Consumers, governments, and businesses are beginning to understand how their interests could be sustained in the long run, using this new approach to water-resource management.”

He also spoke about water as an economic enabler. According to him, harnessing the full benefit of water is constrained by three limits: hydrological limits, limits in production efficiency, limits and risks in externalising water footprints. He further elaborated, “Each river basin is unique with respect to amount of rainfall and pattern, rainfall-runoff relation, total available runoff, environmental flow requirements, groundwater recharge, etc. The actual available quantity of water is determined by all these parameters. Hence, there is a hydrological limit to water use in a river basin/aquifers”. He said: “On the other hand, making a process more efficient comes at a price, marking a limit on local efficiency gains. Similarly, importing virtual water to relieve pressure on local water resources would require second-order resources such as foreign currency, and a political will to move from a ‘water and food self-sufficiency’ policy towards a ‘water and food security’ policy. Enhancing the global water-use efficiency by means of trade has socio-economic limitations.” His current research focuses on unravelling these limits to growth, and on developing a generic analytical framework to find optimal solutions to growth under these water limits.

Trade can relieve the strain

Regarding the latter, he said trade in water-intensive goods and services could help relieve the strain on local/national water resources. For example, Switzerland covers merely 18% of its water demand from its internal water resources, i.e. 82% of it is external! South Africa’s external water footprint is only 22% of the total water footprint of national consumption. Hence, the scope of international trade to help alleviate local scarcity is limited by the availability of second-order resources such as foreign exchange, institutional capacity, socio-political context, etc. 

However, globalisation of fresh water brings both risks and opportunities. “Although national water resources could be saved for best alternative uses, the risks of a growing external dependency and the associated risks related to events elsewhere, are often not visible. These water-intensive production processes are vulnerable to the availability of water at the various locations where the production processes take place. The vulnerabilities may result from a range of factors – from reduced river flows, lowered lake levels, and declined ground-water tables to increased salt intrusion in coastal areas, pollution of freshwater bodies, droughts, and a changing climate,” he said.

Water footprint assessment

Prof Chapagain also touched on the Water Footprint Assessment; he believes it has provided a sound method to analyse the water footprint in the relevant context and formulate appropriate response strategies. “The water-footprint assessment breaks down the different water-footprint components and checks the sustainability of these components against three sets of criteria: environmental, economic, and social. The application of the Water Footprint Assessment has evolved from basic quantitative studies to a powerful advocacy tool that can support decision-making and policy processes and help mitigate water-related business risk.

“Counting water drops is simple, yet unravelling the underlying complexities is the key! I count on you to start by counting water drops in counting for sustainable growth,” he concluded.

Africa and her diaspora grace the Africa Century International Writers’ Conference
2012-10-30

30 October 2012

Programme (Pdf format)

The Africa Century International African Writers’ Conference, organised by the wRite associates, in partnership with the Department of Arts and Culture, the University of the Free State (UFS) and the SABC, will take place on the Bloemfontein Campus of the UFS from 7 to 10 November 2012.This four-day conference will culminate in the 2012 South African Literary Awards ceremony where winners will be honoured.

The conference is dedicated to the memory and contribution of its special advisor and inspiration, Zwelakhe Sisulu, who passed away in October 2012.

The conference has attracted an array of scholars and artists from around the continent. The African diaspora will be one of the main features of the programme. Keynote addresses, the presentation of papers, dance, visual art, comedy, disc jockeying will all feature the Diaspora.
 
“This event will also mark the 21st anniversary of the then-OAU (now-AU) declared International African Writers’ Day (i.e. 7th November). The theme of this is: From Resistance to Creative Mediation: Celebrating a Century of Writing and Literary Intellectuals’ Influence On The Liberation Struggles & Political Impact on Literary Discourse and Development”, said Raks Morakabe Seakhoa, Managing Director of the wRite associates and Project Director of the South African Literary Awards and the Africa Century International African Writers Conference.
 
The patrons of the Africa Century International African Writers’ Conference include; Prof. Kgositsile Keorapetse, Prof. Chinua Achebe, Dr Nadine Gordimer, DrWanguiwaGoro and Dr Hugh Masekela.

“This prospective historical gathering of authors, literary scholars and historians will, as the then-OAU’s Conference of African Ministers of Education and Culture (meeting in Coutonou, Benin, in 1991) resolved, ‘…afford the African people a moment of pause within which to reflect on the contribution of African Writers to the development of the Continent’ ”,Seakhoa added.
 
He said, “We are delighted at the growth of the prestigious South African Literary Awards, as they are now spreading their wings to inaugurate the Africa Century International African Writers’ Conference and opening up to the continent and Diaspora’s writers.”
 
Other highlights of this four-day programme include:

  • An evening with the National Poet Laureate: poetry reading by Prof. Keorapetse Kgositsile and guest poets
  • Nobel Laureate, Nadine Gordimer discusses her latest work, ‘No Time Like The Present’
  • Poetry, comedy and performances
  • Creative writing skills development programme, facilitated by: Prof.KeorapetseKgositsile, Mr Walter Chakela and Dr Oswald Mtshali
  • Tsebo-Lethabo Primary and High Schools programme
  • Books, art & crafts and clothing exhibitions and more
