"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme soil science and water management".
Evaluation of water distribution systems at Igomelo Farmer-Managed Irrigation Scheme in Tanzania
Abstract:
Evaluation of water distribution systems at Igomelo irrigation
scheme was conducted to assess the performance of the scheme
after intervention of the Irrigation Management Transfer (IMT).
The scheme was divided into three blocks: head, middle and
tail end of the scheme. Three plots from each block were
selected for study, where water deliveries were monitored
throughout one irrigation season. Irrigation performance
indicators such as Dependability (PD), Equity (PE) and
Adequacy (PA) of water supply, Conveyance efficiency and
Structure Condition Index (SCI) were used to evaluate the
system. Conveyance efficiency was on average 85% for the
three sections. Dependability and equity values were 0.70,
0.62, 0.84 and 0.76, 0.90 0.96 for head, middle and tail and
sections of the scheme, respectively. The structure condition
index was on average90% for the 3 sections of the scheme.
All the above, are indicators of a system that is performing
well.
L’évaluation des systèmes de distribution d’eau au système
d’irrigation d’Igomelo a été menée pour évaluer le rendement
du régime après l’intervention du Transfert de Gestion de
l’Irrigation (IMT). Le régime a été divisé en trois blocs: le régime
de la tête, du milieu et de la queue. Trois parcelles de chaque
bloc ont été sélectionnées pour l’étude, où les livraisons d’eau
ont été suivies tout au long de la saison d’irrigation. Les
indicateurs de performance tels que l’irrigation de
fonctionnement (PD), l’Equité (PE) et l’Adéquation (PA) de
l’approvisionnement en eau, l’efficacité du moyen et de la
Structure de l’Index de Condition (SCI) ont été utilisés pour
évaluer le système. L’efficacité du moyen de transport était en
moyenne de 85% pour les trois sections. Les valeurs de
fonctionnement et de l’équité étaient de 0,70, 0,62, 0,84 et 0,76,
0,90 0,96 pour la tête, le milieu et la queue et les articles du régime, respectivement. La Structure de l’Indice de Condition
était en moyenne de 90% pour les 3 sections du régime. Tout ce
qui précède, sont des indicateurs d’un système qui fonctionne
bien.
