    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.

  • Treadle Pump Irrigation and Poverty in Ghana

    Type: 
    Publication
    Publication date:
    Objective:
    Sectors:

    Treadle pump (TP) technology has been promoted by Enterprise Works Worldwide (EWW) in West Africa as an alternative to the traditional rope and bucket irrigation that is necessary to overcome the challenge of uncertain and inadequate rainfall for agricultural production. The aim is to improve output, increase income and reduce poverty among rural farm households. This study examines the strategies used for dissemination of the TP and the dynamics of its adoption and impacts, with a special focus on poverty reduction.

  • Dynamics of well irrigation systems and CO2 emissions in different agroecosystems of South Central India

    Type: 
    Publication
    Publication date:
    Objective:

    This study was undertaken to assess the carbon dioxide emissions for different irrigation systems, in the context of growing demand for adaption of pressurised irrigation with electric pumps in South Central India.

    The paper argues that water application systems under wells extracting groundwater are one of the major factors influencing climate change in the agricultural sector.

  • Photovoltaic Pumps: Technical and Practical Aspects for Applications in Agriculture

    Type: 
    Publication
    Publication date:
    Objective:
    Sectors:

    This paper deals with a series of tests conducted on a PV-DC pump. The tests involved measurements of solar radiation, on both a horizontal surface and the tilted module surface, flow rates, volumes, and total dynamic heads. In total, up to 3000 data were collected every day whose analysis allowed the authors to find empirical relationships between system efficiencies, solar radiations and total dynamic heads.

  • Performance and Economic Evaluation of Pumped Irrigation Systems: A Case of Smallholder Horticultural Farmers

    Type: 
    Publication
    Publication date:
    Objective:

    The study was carried out with the objectives evaluating the technical performance of the pumps used in smallholder irrigated agriculture, studying the energy uses during pumping and identifying the possible causes of inefficient energy use, and evaluating the costs of pumping used during irrigation. A study to identify the occurrence of pumped irrigation systems in Thika and Yatta District, Kenya was done.

  • The Case for the Rope-Pump in Africa: A Comparative Performance Analysis

    Type: 
    Publication
    Publication date:
    Objective:
    Sectors:

    According to this paper, an alternative to standardised imported hand pumps is the locally manufactured rope pump, which is considerably cheaper and easier to maintain but has been rejected in the past because of fears of impaired water quality. This paper presents the key aspects of a study in northern Ghana that compared the performance of rope pumps with that of conventional hand pumps, to determine whether the rope pump provides a viable alternative for community water supplies across the subcontinent.
