Toelichting


SamSamWater maakt informatie over water en sanitatie beschikbaar en toegankelijk voor iedereen.

Hierom hebben we een database opgezet, die via deze pagina geraadpleegd kan worden. De database bevat allerlei informatie, bijvoorbeeld 'best practices' (bewezen technieken), kaarten, geo-informatie en achtergrondinformatie. De informatie is afkomstig van verschillende bronnen, waaronder onderzoeksinstituten, bedrijven, organisaties en overheidsinstellingen.

Als u informatie heeft die wij in onze database kunnen opnemen, of als u opmerkingen of vragen heeft, dan horen wij dit graag!

Drip Irrigation; Options for smallholder farmers in eastern and southern Africa


Isaya V. Sijali, Sida's Regional Land Management Unit (2001)

Smallholder farmers in the semi-arid regions of eastern and southern Africa have to depend on erratic, unreliable and low rainfall for their livelihoods. Subsistence staple food crops are generally grown under rainfed conditions. Consequently there is a growing interest in complementing this risky rainfed food production with cultivation of high-value vegetable crops and fruits. But in most cases this means these small-scale vegetable gardens and orchards must be irrigated in order to assure an economic return. Drip irrigation methods minimize the non-productive water losses associated with conventional irrigation, e.g. from evaporation and soil runoff, and thus can make more efficient use of the already minimal water supplies in these arid areas. But until recently drip irrigation technology had been associated with costly investments available only to large commercial farmers. Now there is growing interest in the technique and many efforts are being made around the world to develop low-cost, simple, drip irrigation systems suitable for smallholder farmers. This handbook presents some of these drip irrigation options that can be promoted by extension officers in eastern and southern Africa. It describes the most interesting small-scale low-cost drip irrigation methods of which the author and the other contributors have practical experience. It also gives a brief overview of methods that have been used successfully in other parts of the world with details of how to obtain further information about them or order equipment. (source)

Low-cost methods of rainwater storage; Results from field trials in Ethiopia and Kenya


Kithinji Mutunga, Will Critchley, Sida's Regional Land Management Unit (2002)

Rainwater harvesting is one solution to the problems of water shortage in the drier areas of Africa, but its implementation presents a number of challenges, of which storage is the main one. Many people in rural areas who would like to harvest rainwater lack the resources to do so. Conventional stone, brick or ferrocement tanks are costly, and therefore there is a great need for cheaper alternatives. This publication gives an account of two trials conducted in 1998/99 to investigate some such alternatives. In Ethiopia, five different methods of tank construction were tested in the suburbs of Nazareth town in Adama Woreda. In Kenya, six different methods were tested during the same period at various locations in Machakos and Makueni Districts. A main feature of the alternative tank designs is that they are built underground, which reduces the need for reinforcement materials. (source)

Water from sand rivers; A manual on site survey, design, construction and maintenance of seven types of water structures in riverbeds


Erik Nissen-Petersen, Sida's Regional Land Management Unit (2000)

Sand rivers, also called dry riverbeds, transport rainwater run-off from highlands to the sea through the most dry parts of this planet where water is very scarce. Although flood water may be drawn from the sand in some riverbeds for a short period of time after floods, the big majority of sand rivers are dry throughout the years. This book explains in simple terms how dry riverbeds can be changed into water sources for long periods after floods - and in some cases throughout the years. The usual problems of contamination and evaporation in hot climates are almost eliminated due the water being trapped and stored underground between the sand particles of riverbeds. This book is based on the author’s practical experience on developing affordable water supply systems in some of the driest parts of Africa and Asia over the last 25 years. (source)
