Economic accounting of water: The Botswana experience

Publication date: Available online 10 October 2016 Source:Physics and Chemistry of the Earth, Parts A/B/C Author(s): T. Setlhogile, J. Arntzen, O.B. Pule Water accounts aim to capture the value of water resources and their use within the economy. The accounts complement the National Accounts as the latter’s main indicator (GDP) does not reflect changes in natural capital. Botswana developed water accounts for the period 2010/11 – 2014/15 using the UN’s standard System of Environmental Economic Accounting for water (SEEA-water). The article focuses both on the construction of physical flow accounts as well as on the policy implications for development planning and water resource management through the use of policy indicators. It also shows long-term trends in water abstraction and water use efficiency linking the SEEA water accounts with results of earlier (non-SEEA) water accounting projects in Botswana. The water accounts results show that water abstraction and consumption have been largely stable since 2010/11 despite population (1.9% p.a.) and economic growth (around 5% p.a.) likely due to a combination of water sector reforms and drought conditions in south eastern Botswana; the latter led to the drying up of several dams and the imposition of severe water restrictions. While public attention focuses mostly on water service providers, self-providers (mines and the agricultural sector) account for more than 50% of total water abstracted from the environment of ...
