Australia is a relatively dry continent with an average runoff of 50 mm per year. The use of water resources in some river basins is approaching the limits of sustainability. Some adverse environmental impacts have been observed resulting from water diversions and from both reclaimed water and stormwater discharges. The paper describes current water recycling initiatives in Australia. These include: beneficial reuse of reclaimed water for urban, residential, industrial and agricultural purposes; recycling of greywater and stormwater; advanced treatment using membrane technology; and water efficient urban design. Some possible water recycling scenarios for Australia in the 21st century are examined. The implications of these scenarios are discussed.

The paper analyses changes in potential evaporation E0 (mm) in north-western Poland in the years 1952–2018. E0 (mm) has been calculated according to Ivanov’s formula based on the monthly values of air temperature (t, °C) and relative air humidity (f, %) for six weather stations of the Institute of Meteorology and Water Management. The data were collected using the Statistica software ver. 13 and the QGIS software ver. 3.80. The results indicate statistically significant trends in the increase of E0 during the period 1952–2018, and that it is particularly high during the spring and summer months, which should be associated with a statistically significant increase in air temperature and a decrease in relative humidity at all examined stations. The results also indicate an exceptionally high increase in evaporation since the end of the 20th century and in the 21st century, which reflects a potentially higher risk of permanent changes in hydrological conditions. The research results point to the major role of climatic factors in the often-dramatic decreases in water resources observed in the 21st century, particularly in lakes and small watercourses. The progressing reduction of water resources may cause permanent changes in physical and chemical conditions in waterbodies.

The implementation of principles for water governance is widely accepted but challenging for the whole water sector of a developing country like Zambia, because of the legal and administrative changes and organizational requirements involved. In February 2010, a revised water policy for Zambia was approved by the Cabinet. The revised National Water Policy 2010 aims to improve water resources management by establishing institutional coordination and by defining roles as well as responsibilities for various ministries. Taking into account the previous political and administration changes, this paper points out the problems and challenges of the implementation of good water governance mechanisms in Zambia. Focusing on the Kafue River Basin, from which water is abstracted for a variety of conflicting purposes (like municipal supplies, industrial use, mining, irrigation of agricultural land, fishery activities, wetland reserves and hydropower production), the gaps in implementing good water governance and Integrated Water Resources Management (IWRM) in Zambia are identified, as well as the factors causing these gaps in the Zambian water sector. The paper finishes with a overview of the opportunities given by the new water policy through Water User Associations (WUAs) at a local level.
