INTRODUCTION

Towards better measures of wealth Economic development is a

process of building wealth and managing a portfolio of assets

Natural Capital Accounting is focused on the part of total wealth that comes from land, water, mineral, energy, soil, forests and timber, and ecosystem assets

POSSIBLE APPLICATIONS Determining the impacts on water resources as a result of economic growth, the patterns of

domestic consumption, and international trade

Determining the specific contributions of economic activities to the various pressures on water resources, such as pollution and over abstraction, as well as the opportunities for reducing these pressures

Evaluating the possible future water demands under alternative economic development scenarios and determining their sustainability

Understanding how changes in sector policies such as agricultural, energy, forestry, land, etc. can affect water resource utilization

Linking and enhancing with already existing initiatives such as the Integrated Water Resource Management Information System (IWRMIS) under the Water Resources Management Agency (WARMA) required for capturing and storage of integrated information on environment, water and economic sectors. The database for this would need to be configured along the lines of the International Recommendations for Water Statistics (IRWS) (UN, 2012a)

WAVES Partnership in LAC 11 WAVES © 2014

WAYFORWARD Develop a water statistics database for Zambia following the International

Recommendations for Water Statistics (IRWS) and link this with the Smart Zambia framework; including legal and institutional arrangements to operationalize this

Mainstream water statistics and natural capital accounting (NCA) for water (NCA) into the operations for the Ministry of Water Development, Sanitation and Environmental Protection (MWDSEP) and the Central Statistical Office. A key outcome of this would be the production of annual water statistics and water accounting tables;

Build human and institutional capacity for water accounting under MWDSEP, CSO & MNDP; and

Ensure that policy actions are informed by the water accounts and statistics.
