The accounts cover the period 2015-16 but also highlight the 2010-11 to 2014-15 trends. Three (3) earlier reports have been published, covering the years 2010-11 to 2014-15 (DWA and CAR, 2013, 2015 and 2016). The SEEA styled water accounts for Botswana started in March 2012 when the Government of Botswana (GoB) entered into a partnership with the World Bank (WB) to develop accounts for natural resources and to value ecosystem services under the Wealth Accounting and Valuation of Ecosystem Services (WAVES) Programme. The WAVES initiative has since become a continuous activity of the Department of Water Affairs (DWA)’s road map towards sustainability as per Sustainable Development Goal (SDG) number 6. The Water Accounting (WA) activities of WAVES-Botswana have gone several phases with the current phase signifying full institutionalization of the accounts. The DWA is currently undertaking the updating of the accounts on their own without support of full- time consultants and this is a major achievement within the institutionalization roadmap. The current Botswana Water Accounts are based on the United Nation’s System of Environmental– Economic Accounting for Water (SEEA-Water; UN 2012). The framework describes the hydrological system (assets or stocks) in terms of a country’s water resources existing at a certain point in time, the exchanges between water resources, flows of water from the environment and within the economy in physical and monetary terms and also captures water quality issues. It also considers water- economic interactions, which is important for addressing cross sectoral
