    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.

  • New CTCN/UNIDO Call for Proposals: Water and energy efficiency and self-generation plan in the Solomon Islands

    CTCN
    Publication date
    Objective
    Mitigation
    Sectors
    Energy efficiency

    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. 

  • Solar water pumps

    Renewable energy
    Objective
    Mitigation

    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.

  • SISAM: strengthening women’s access to Improved Solar Irrigation Systems in West Africa

    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.

  • Greenhouse Gas Implications of Water Reuse in the Upper Pumpanga River Integrated Irrigation System, Philippines

    Publication date
    Objective
    Mitigation

    Enhancing water productivity is often recommended as a "soft option" in addressing the problem of increasing water scarcity. In this study, authors analysed the water productivity and GHG implications of water reuse through pumping groundwater and creek water, and compare this with gravity-fed canal irrigation in the Upper Pampanga River Integrated Irrigation System (UPRIIS) in the Philippines. Water productivity indicators show that water reuse contributes significantly to water productivity.

  • Global System for Mobile Communications (GSM)-Enabled Remote Monitoring of Rural Handpumps: A Proof-of-Concept Study

    Objective
    Adaptation
    Sectors
    Water

    This paper reports on the design and testing of a new water-point data transmitter that can provide reliable real-time data on hand pump usage to address this information deficit. Using a low-cost integrated-circuit based accelerometer, the transmitter automatically monitors the number of strokes made in operating a hand pump, and then transmits this information over the Global System for Mobile Communications network.

  • Can Market-Based Approaches to Technology Development and Dissemination Benefit Women Smallholder Farmers? A Qualitative Assessment of Gender Dynamics in the Ownership, Purchase, and use of Irrigation Pumps in Kenya and Tanzania

    Approach
    Gender

    Rural household economies dependent on rainfed agriculture are increasingly turning to irrigation technology solutions to reduce the effects of weather variability and guard against inconsistent and low crop output. Organisations are increasingly using market-based approaches to disseminate technologies to smallholder farmers; and, although women are among their targeted group, little is known of the extent to which these approaches are reaching and benefiting women.

  • Solar Pumps for Sustainable Irrigation in India

    Publication date
    Objective
    Mitigation
    Approach
    Community based

    Researchers in this study put forward a budget-neutral approach for incentivising the adoption of solar pumps in India.

    The study also looks at parity between solar and electric pumps from economic perspective, i.e. NPV (net present value) of the expenses to be incurred by the farmer. 

    It further explores mechanisms for promoting the deployment of solar pumps, and the need to assess the suitability of solar pumps in providing sustainable irrigation, before they are scaled up.

  • Efficient motor

    Efficient motors

    Fans, pumps and compressors use electric motors to provide motion; therefore its energy consumption is strongly influenced by the efficiency of motor. According to IEC 60034-30, efficiency of motors are categorized as follows (IE stands for international efficiency).
