Access to safe water in rural and urban areas in Zimbabwe Access to safe water in rural and urban areas in Zimbabwe
Zimbabwe’s total annual renewable freshwater resources amount to 20 cubic km per year, and although the country experiences quality and dry season problems at present, continued pressure on the resource will lead to water stress by 2025 (Hirji et al. 2002). Poor infrastructure hampers access to water in most urban areas, and in the capital, Harare, and the second main city, Bulawayo, residents have gone without piped water for as long as two we...

Proportion of population without access to improved sanitation in Zambia Proportion of population without access to improved sanitation in Zambia
The proportion of national population without sustainable access to an improved water source had dropped below 40 per cent by 2008 and is on course to meet the MDG target of 25.5 per cent by 2015. With respect to sanitation, however, the situation is getting worse, and the proportion of the population without access to good sanitation rose by more than 10 per cent from 26 per cent in 1991 to 36.1 per cent in 2006, far from the target of 13 per ce...

Access to safe water for the urban and rural population in Zambia Access to safe water for the urban and rural population in Zambia
Although Zambia has serious challenges of water pollution arising from contamination by sewage and toxic industrial chemicals in mining areas, the country continues to sustain the provision of improved water supply to urban areas, although access in rural areas remains below 50 per cent, as shown in the figure.

Freshwater availability per capita in Zambezi River Basin countries Freshwater availability per capita in Zambezi River Basin countries
The water flow in the Zambezi river is estimated at 3 600 cu m per second. This represents about 87 mm/year of equivalent rainfall and less than 10 per cent of the average rainfall in the basin (Shela 2000). The average annual rainfall in the basin is about 950 mm/year (Mitchell 2004), but is unevenly distributed across the basin. The southern and western parts of the basin receive less rainfall than the northern and eastern parts. The more den...

Water footprint Water footprint
In the past decade the Asia-Pacific region has become the largest consumer of natural resources in the world. This includes water, raw materials and energy resources. Water resources are unevenly distributed in the region. With climate change increasingly causing drought and precipitation, enhanced water efficiency and management is a challenge not only for direct water users, water managers and policy makers, but also for business and consu...

Recent flood events in the Hindu Kush-Himalaya region Recent flood events in the Hindu Kush-Himalaya region
Extreme vulnerability to natural hazards among countries in South Asia is cyclical and repeatedly causes major setbacks in the socioeconomic and equitable development of the region. According to UN estimates major disasters may cut the GDP of countries in the region by up to 20 per cent. Climate change is expected to increase both the frequency and magnitude of hazards leading to disasters. It calls for speedy action to help communities...

Water management in Central Asia: state and impact Water management in Central Asia: state and impact
The withdrawal of water for irrigated agriculture has caused a social and environmental crisis in the Aral Sea Basin. Drying up of the sea has been accompanied by a wide range of other environmental, economic and social problems in the basin. The problems precipitated by this crisis have aggravated the social and economic difficulties caused by the collapse of the Soviet Union. Following the break- up of the Soviet Union the interests of Up-strea...

Transboundary river basins of the Balkans, detail Transboundary river basins of the Balkans, detail
All the Balkan countries are now committed to the European integration progress, with the goal of joining the European Union. They must consequently accept the acquis communautaire and transpose it into their national legislation. One major challenge – and not just for new member states – is the Water Framework Directive, which introduces new rules for water management hinging on transboundary river basins.

Transboundary river basins of the Balkans, overview Transboundary river basins of the Balkans, overview
Prior to 1992, there were only six transboundary river basins in the Balkans, but after the break-up of former Yugoslavia, the number more than doubled. There are now 13 internationally shared river basins and four trans-boundary lake basins. Such a fragmented situation means that new international legal regimes specifically for water basins need to be worked out. Talks between the countries concerned are also essential to develop future policies...

Qanat Qanat
A qanat is a water management system used to secure reliable water supply to human settlements or irrigation in semi-arid and arid regions. Probably originating in Persia, the qanat system has been adopted and developed further in large parts of Asia and Europe. Its widespread use is refected in the many names for the system and similar systems; kariz/kahan (Persian), khettara (Morocco), galeria (Spain), falaj (United Arab Emirates and Oman), ...
