Localized Institutional Actors and Smallholder Irrigation Scheme Performance in Limpopo Province of South Africa

Abstract

Poor performance bedeviling SISs in South Africa is attributed to poor institutional integration, consequently impacting service delivery. Despite this, local institutional actors (LIAs)’ role has not been documented as a potential entry point to address poor performance and hence increase SISs’ sustainability. This study sought to assess the role of LIAs on the performance of the Tshiombo irrigation scheme (TIS). Structured questionnaires, key informant interviews (KIIs), and focus group discussions (FDGs) were used for data collection. Yield data for sweet potato, the main crop grown in the scheme, was measured as a proxy indicator for performance. Ordinary least square regression model was used to assess the relationship between LIAs and scheme performance after reducing the data using principal component analysis. The study revealed that institutional factors such as community credit support, academic extension support, academic institution market and input support, community maintenance support, and community input support positively and significantly (at 5% level) improved the yield by a margin of 0.49, 0.12, 0.1, 0.36, and 0.10. Assessing institutional actors’ interaction within each scheme will help develop linkages that will enable sustainability of irrigation schemes. Out scaling of research on LIAs on irrigation scheme performance enhances scheme performance.

Factors Influencing the Adoption of Climate-Smart Irrigation Technologies for Sustainable Crop Productivity by Smallholder Farmers in Arid Areas of South Africa

“…Ordinary Least Squares (OLS) has been identified as one of the most popular methods used for data analysis because it can be applied to single, multiple, or appropriately coded categorical explanatory variables however, it mainly assumes linearity, which was satisfied by the data used for this study [60,61]. However, the model would result in biased and inconsistent estimates [61].…”

Using principal component analysis to explore consumers' perception toward quinoa health and nutritional claims in Gweru, Zimbabwe

“…The patterns and influence of sociodemographic on nutritional or health variables were identified using PCA. The PCA is a statistical approach used to reduce large data sets into smaller data sets without losing much of the original sample data (Mwadzingeni et al., 2020; Vyas & Kumaranayake, 2006). Principal components (PC) differ in the number of variables with higher weighting, defining PC's characteristics.…”

The Efficacy of Agricultural Cooperatives Towards Enhancing Food Security in Rural Areas: Mbombela Local Municipality, Mpumalanga Province

“…Cooperatives have a comparative advantage in terms of job creation over other types of businesses because they are labor-intensive by nature, they are cost-effective due to member commitment and participation which makes job creation sustainable (Brixiová, Kangoye and Yogo, 2020). Consequently, the commitment and participation of cooperative members encourage agricultural cooperatives to be an excellent tool for increasing agricultural production through new agricultural skills development and market accessibility (Mwadzingeni et al, 2020).…”
