Water footprint important but misunderstood indicator
Water footprinting is the future of water conservation
The Water Footprint (WF) of a product, process or person provides an indication of how much fresh water is used, both direct and indirect, to produce a product, drive the process or lead a lifestyle. Although it is a very important indicator it is often misunderstood. Popular media contribute to this misunderstanding as they often use the WF to illustrate the large quantities of water used to produce a product without explaining what the footprint actually means.  

An example is a single kilogram of beef that has an average global WF 15 415 litres. This indeed sounds scary, but when one places it in context, the total WF includes 14 414 litres green water, 550 litres blue water and 451 litres grey water. Green water is the evapotranspiration of precipitation (rain), blue water is the fresh water from dams, rivers and underground sources, while grey water is the amount of fresh water required to dilute polluted water to acceptable levels.

According to Frikkie Maré, a lecturer at the Department of Agricultural Economics at the University of the Free State (UFS), the WF concept provides a new look at water conservation and sustainability. “Although the WF is not an indicator of sustainable water use, it is a useful tool to calculate total water demand and is used in the estimation of sustainability. Traditionally, water conservation was focused on the direct water use of individuals (time taken to shower, leaking taps etc.), but the WF now provides a tool to focus attention on total water demand.”

The Water Footprint Network assists individuals with this new trajectory on the water conservation front with the personal water footprint calculator that allows individuals globally to determine their personal water demand through their direct and indirect water usage. Maré believes this can cause the necessary paradigm shift in the aqua status quo by creating awareness among consumers on their total water demand.

With Water Week underway from 17-23 March 2018, UFS students and staff members are urged to make use of the personal water footprint calculator in order to become aware of the real importance of fresh water in our everyday lives.

Prisca Odero awarded ASA Presidential Fellowship

Dr Prisca Odero, a Centre for Africa Studies (CAS) fellow, received the African Studies Association (ASA) Presidential Fellow award in Indianapolis, USA, recently.

She was nominated for ASA by Dr Cyril Obi from the Social Science Research Council (New York), and was selected competitively, based on her PhD thesis and applied research work in rural development in Africa. Odero obtained her PhD in Africa Studies from the UFS at the July 2014 Graduation Ceremony.

On 22 November 2014, Dr Odero gave a public lecture at the Brooklyn College of the City University of New York. The event was hosted by the Political Science Department at the College.

Her paper, titled Sources and role of social capital in smallholder agricultural production: The value of membership of community groups to Zimbabwe rural livelihoods, sought to address the question of whether social capital contributed to the resilience of rural households in the face of economic difficulties and food security challenges. Dr Odero argued that the link between social capital and agricultural production is manifest in the ways in which farmers use social capital derived from membership of groups to alleviate agricultural production challenges.

Smallholder farmers in Zimbabwe, who face constraints in acquiring the necessary resources for production because of failing markets and reduced agri-industry productive capacity, employ a range of methods to deal with these challenges.  She presented an analysis of data collected through focus group discussions with representative groups and through a household survey.

Dr Odero’s research forms part of a book project. While books on agricultural development knowledge do exist, more studies analysing issues and offering solutions from an African perspective would help to address the gap in African knowledge production.
