Suhardiman, DianaSilva, Sanjiv deArulingam, IndikaRodrigo, SashanNicol, Alan[Review of water and climate adaptation financing and institutional frameworks in South Asia. Background Paper 3]Review of water and climate adaptation financing and institutional frameworks in South Asia. Background Paper 3

Groundwater quantity and quality may be affected by climate change through intricate direct and indirect mechanisms. At the same time, population growth and rapid urbanization have made groundwater an increasingly important source of water for multiple uses around the world, including southern Af...


McGill, B.M.Altchenko, YvanHamilton, S.K.Kenabatho, P.K.Sylvester, S.R.Villholth, Karen G.[Complex interactions between climate change, sanitation, and groundwater quality: a case study from Ramotswa, Botswana]Complex interactions between climate change, sanitation, and groundwater quality: a case study from Ramotswa, Botswana
Evans, A.Mateo-Sagasta, JavierQadir, M.Boelee, ElineIppolito, A.[Agricultural water pollution: key knowledge gaps and research needs]Agricultural water pollution: key knowledge gaps and research needs

A reliable supply of water is critical for agricultural intensification and yield improvement. Technological devices that lift, transport and apply water contribute to increased yield from improved crop varieties and high input cultivation. The increasing use of motor pumps is a significant contr...


Aheeyar, Mohamed M.M.Manthrithilake, HerathRanasinghe, ChathurangaRengaraj, ManoojGamagedara, YasasBarron, Jennie[Mechanizing water lifting through pumps: a case study in Sri Lanka]Mechanizing water lifting through pumps: a case study in Sri Lanka

Most cities in developing countries fail to treat their wastewater comprehensively. Consequently, farmers downstream use poor-quality water for irrigation. This practice implies risks for farmers, consumers and the environment. Conversely, this water supply supports the livelihood of these farmer...

Phosphorus (P) is a critical, geographically concentrated, nonrenewable resource necessary to support global food production. In excess (e.g., due to runoff or wastewater discharges), P is also a primary cause of eutrophication. To reconcile the simultaneous shortage and overabundance of P, lost ...


Mayer, B.K.Baker, L.A.Boyer, T.H.Drechsel, PayGifford, M.Hanjra, Munir A.[Total value of phosphorus recovery]Total value of phosphorus recovery

Billions of people currently lack clean water and sanitation. By 2050 the global population will have grown to nearly 10 billion, over two-thirds of whom will live in urban areas. This Voices asks: what are the research and water-management priorities to ensure clean water and sanitation in the w...


Jamwal, P.Brown, R.Kookana, R.Drechsel, PayMcDonald, R.Vorosmarty, C.J.Vliet, M.T.H. vanBhaduri, Anik[The future of urban clean water and sanitation]The future of urban clean water and sanitation

When urban areas expand without concomitant increases in wastewater treatment capacity, vast quantities of wastewater are released to surface waters with little or no treatment. Downstream of many urban areas are large areas of irrigated croplands reliant on these same surface water sources. Case...


Thebo, A.L.Drechsel, PayLambin, E.F.Nelson, K.L.[A global, spatially-explicit assessment of irrigated croplands influenced by urban wastewater flows]A global, spatially-explicit assessment of irrigated croplands influenced by urban wastewater flows

Load estimates are more informative than constituent concentrations alone, as they allow quantification of on- and off-site impacts of environmental processes concerning pollutants, nutrients and sediment, such as soil fertility loss, reservoir sedimentation and irrigation channel siltation. Whil...


Slaets, J.I.F.Piepho, Hans-PeterSchmitter, Petra S.Hilger, T.Cadisch, Georg[Quantifying uncertainty on sediment loads using bootstrap confidence intervals]Quantifying uncertainty on sediment loads using bootstrap confidence intervals

Maintaining indigenous nutrient supply and positive nutrient balances are key factors in sustaining rice yields. Irrigation systems act as conveyers for water, sediments and nutrients throughout landscapes, especially in mountainous, cultivated tropical areas where erosivity is usually high. Cont...
