Evaluation of Development-relevant Infrastructure Development Programme ORIO

Kilimanjaro International Airport

The external evaluation of the ORIO programme assessed its achievements so far. Its main objectives were:

  • to determine the relevance, effectiveness, efficiency, additionality and policy coherence of the ORIO programme;
  • to learn from the assessment of the functioning and effects of the ORIO programme and the use of resources, in order to generate relevant information for the improvement of similar programmes.

The evaluation focused on the period from 2009 to the end of 2018 and addressed key issues at both the programme level and the project level. It combined qualitative research, based on a study of documents and interviews with stakeholders, with quantitative research, based on data from the portfolio of projects and data collected for the following case studies:

  • Enhancement of maternal Health and Paediatric Service in the Zanzibar archipelago, Mnazi Moja Hospital, Tanzania;
  • Rehabilitation of Kilimanjaro International Airport, Tanzania;
  • Development of the Port of Ziguinchor, Senegal;
  • Satellite-Based Water Monitoring and Flow Forecasting System for the Niger River Basin, Niger.

As far as available, it made use of findings of six impact assessments (being) conducted by external consultants under separate contracts.

The team of consultants for the evaluation was led by Nico van der Windt (Erasmus University Rotterdam) and furthermore comprised Elena Gross (University of Bayreuth), Martin van der Linde (independent researcher), Niek de Jong, Dr. Ogenis Brilhante, Floris de Haan, Jan-Jelle Witte and Prof Dr. Geske Dijkstra (all of Erasmus University Rotterdam). Viviana Cordero Vinueza provided helpful research assistance. The following evaluators also contributed to the underlying case studies of this evaluation: Dr. Stephen Kirama from Tanzania, Mr. Ousseynou Diop from Senegal and Ms. Fannata Souleymane Mamdou Mari from Niger.

Impact evaluation Electrifying Rural Tanzania: A Grid Extension and Reliability Improvement Intervention

Electrifying Rural Tanzania, a rigorous impact evaluation

As assignment under the Framework Contract with the Netherlands Enterprise Agency RVO, the Erasmus University Rotterdam, the Rheinisch-Westfälisches Institut für Wirtschaftsforschung and the Georg August Universität, Göttingen (with the Economics Department of the University of Dar es Salaam as local partner) conducted an impact evaluation for the Electrifying Rural Tanzania project, financed through the Dutch Facility for Infrastructure Development ORIO. The aim of the ORIO project was toreplace old existing diesel generators in three rural townships by modern state-of-the-art generators and to extend the local electricity grids to surrounding rural areas.

The rigorous impact evaluation was conducted between 2014 and 2019. For rural households, a quantitative difference-in-differences (Diff-in-diff) approach was used in two survey waves with 58 treatment communities and 42 control communities with a four to five year interval between the surveys. For urban households and enterprises, a before-after quantitative comparison was applied. In total, 1155 households were surveyed in rural areas and 300 households and 595 enterprises in towns. The main conclusions was that the project was overtaken by the speed of the roll-out of the electricity grid, while at the same time rural households made increasingly of solar panels; for urban households the project contributed to stability in electricity supply that is important for entreprises.
