    Context

    Pumping of water for domestic and productive uses has been difficult to maintain in Tanzania. This challenge is highly attributed by the higher costs of pumping water using conventional means such as diesel generators and electricity.

    Solar Photovoltaic (PV) technologies have enabled rural communities of Tanzania to apply this technology for lighting, water pumping, charging of cell phones, etc. Community water projects using solar pumps have benefitted from reduced running costs as compared to diesel or electric water pumps.

    Solomon Islands comprise hundreds of islands.  Solomon Islands Water Authority (SW), a state-owned enterprise, is mandated to operate as the provider of municipal water and wastewater services. About 95% of total installed capacity of electricity generation in Solomon Islands is based on fossil fuels, and the balance 5% is through renewable energy sources. The electricity tariff of Solomon Islands is one of the highest in the Pacific since a major share of electricity in the Islands is met through fossil fuels. 

  • Tamar Technological Development r seals eliminate leakages in the main factories in Israel and were successfully installed in .USA Italy Brazil and Netherlands. The new MTZ shaft sealing technology has been introduced by Tamar Technologies This product is especially effective in sealing pumpage with particulates as well as for clear liquids It has application for pumps mixers agitators ribbon blenders and fans in addition to sealing shafts for dry powder handling. The Tamar Seal is analogous to a double mechanical seal that uses a flexible sealant as a barrier fluid.

    Mekorot implements state-of the-art technological solutions and cutting-edge processes that succeeded in maximizing the utilization of Israel’s water resources. The systems include a national network of fully-automated control centres. These centres ensure the continuous functioning of Mekorot’s 3000 water installations including wells pumping stations treatment facilities reservoirs and pipelines. Advanced communications devices provide online real-time information about water quality and water supply while allowing remote control of vital systems.

  • Objective

    A reliable and clean water supply is an essential need but a large number of people currently lack this basic provision. Solar water pumps is a socially and environmentally attractive technology to supply water. Especially if the need for water is in remote locations which are beyond the reach of power lines, solar power is often the economically preferred technology.

    Description of the project: SISAM project is an innovative solar irrigation solution (local, sector, affordable, renewable, adapted to the constraints of family farming) that meets the needs of 100 market garden farms, mostly managed by women who have little access to water. A local production line and distribution of pumps, known as "minivolanta", have been built, as well as access to local microfinance (micro leasing). Activities include production, financing, distribution, maintenance of pumps and irrigation installations.

    Small-scale private irrigation schemes have been the driving force behind the expansion of irrigated areas in Nigeria, despite government efforts to promote large-scale public irrigation schemes. This article empirically assesses the effect of unobserved transaction costs for Nigerian farmers" when investing in irrigation pumps, using the baseline survey data for the Second Fadama Development Program (Fadama II).

    Objective

    This report is a review of irrigation technologies for smallholders in the context of improving rural livelihoods, especially in regards to the prospects for sub-Saharan Africa. The role of traditional technologies is evaluated and modern water distribution technologies, such as sprinkler and trickle irrigation, are reviewed. Low-cost irrigation systems, including such innovations as the use of treadle pumps and drip-kits are then examined.
