Abstract

Water constraints are becoming a major restriction for different economic sectors. The agricultural sector is one of the most affected, but according to experts, the use of irrigation technologies and scheduling can keep productivity high while diminishing the use of water resources. Although irrigation technology is available, for various reasons the rate of adoption is rather low. This article uses a recursive bivariate probit model to examine the impact of social, human, and physical capital on the adoption of irrigation technology and scheduling. The study was conducted in vineyard farms in the Maule and O’Higgins regions of Chile, from which a sample of 452 large, medium, and smallholders was drawn. The average planted area is 37 hectares, ranging from 0.5 to 810 hectares. The adoption rate of irrigation technology is 43 % and for scheduling instruments, 23 %. Results show that adopting irrigation technology increases the chance of adopting scheduling by 31 % and that these adoption decisions are jointly made. While size of the vineyard is relevant in irrigation technology adoption, it is not for scheduling and, in contrast, the use of the Internet is relevant for adopting scheduling but not for irrigation technology. A relevant result is that networks and trust are important factors in explaining the adoption of both technologies.

Notes

  1. The Maule region is located in Central-South Chile (35 25\(^{\prime }\)36\(^{\prime \prime }\)S, 71 39\(^{\prime }\)78\(^{\prime \prime }\)O), and its main agricultural activity is fruit and vineyard production.

  3. Instruments include metrological stations, soil or plant sensors, and pan evaporation.

  4. The municipalities were, in order of number of surveyed producers: San Javier, Sagrada Familia, Curicó, Nancagua, Villa Alegre, Santa Cruz, Talca, Palmilla, San Clemente, Peralillo, Río Claro, Requinoa, Chimarongo, Maule, San Vicente, and Peumo.

Appendix A: Description of trust variables

Table 4 Factor analysis results of the component Trust in General (Cronbch‘s Alpha: 0.762)

A factor analysis was performed to obtain the components of social capital. To elicit the components, we used a list of statements that the farmers rated according to a Likert scale from 1 to 5. Five components were elicited as listed below:

  1. Component 1:

    Networks

  2. Component 2:

    Trust in Institutions

  3. Component 3:

    Trust in Water Communities

  4. Component 4:

    Trust in General

  5. Component 5:

    Norms

In the model we use the component Trust in General since it covers a wider range of statements that, according to Solano et al 2003; Eastwood et al. 2012, are more relevant in determining adoption. Table A.1 present the results for this specific component.
