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.

DiMTEC and insurance industry join forces to address the vulnerability of communal and commercial farmers
2015-09-18

At the workshop on index-based insurance for the
agricultural sector were, from the left:

The United Nations identified climate resilience as a major focus for future development to ensure a safer world for all. Tailor-made insurance and financial products ought to address the needs of the most vulnerable.

Recent research done by the Disaster Management Training and Education Centre for Africa (DiMTEC) at the University of the Free State on the vulnerability of communal and commercial farmers to external shocks highlighted the importance of insurance as an important disaster risk transfer tool. Insurance is generally unavailable to most vulnerable groups, such as communal farmers, small-holding farmers, and new commercial farmers.

For these reasons, DiMTEC invited the insurance industry and other experts to a workshop with the purpose of investigating the development of risk transfer products, especially for drought. They were the hosts of a workshop entitled “Global Resilience through Insurance and Index-Based Risk Transfer Products (IBRTP)”.

Bertus Kruger from Agriseker and Johan van der Berg from SANTAM, together with other experts, attended the workshop facilitated by Dr Andries Jordaan, Head of DiMTEC.

The group attending the workshop, agreed on the following:

- Establishing a UFS-DiMTEC-led research team to investigate the feasibility of index insurance products.
- Mobilising government support to develop risk transfer products for the most vulnerable.
- Initiating forum discussions on risk transfer products.
- Promoting collaboration between the private sector, government, and research institutions with the focus on resilience-building through financial and insurance products.
