    Irrigation subsidy policy in Chile: lessons from the allocation, uneven distribution and water resources implications
    (2021) Jordan, Cristian; Donoso H., Guillermo; Speelman, Stijn
    Globally irrigation subsidies are utilized to boost modernization and increase irrigation efficiency. This paper examines the effects of the irrigation subsidy programme in Chile by reviewing 32 years of allocations and exploring the drivers and consequences of the subsidy programme with a clear market approach based on competition and a state risk-free strategy. Our analysis reveals that, despite the flexibility in targeting, the results indicate an uneven allocation to smallholders' detriment, a state inability to identify farmers' needs, market concentration and a bias towards agricultural expansion. As long as the programme remains unaltered, it will threaten agriculture and water resources' sustainability.

    Measuring the effect of improved irrigation technologies on irrigated agriculture. A study case in Central Chile
    (2021) Jordan, Cristian; Donoso H., Guillermo; Speelman, Stijn
    Irrigated agriculture is the primary sector demanding water resources in the world. Given that, improved irrigation technologies could play a crucial role in enhancing water use efficiency. This paper uses causal inference estimators to evaluate the effect of these technologies on irrigators at the farm level in two irrigated valleys in Central Chile. Doubly robust estimators were employed to address the selection bias of the adoption of improved irrigation technologies. The results show first a low level of technology adoption, with only 18% of irrigators adopting irrigation, where access to credits and education plays a crucial role in their adoption. Despite this low rate, the estimates show consistently positive and significant impacts on adopters in terms of annual margins and land use. As a result, our research calls for attention towards focusing programs and policy targeting on reducing entry barriers and broadening the adoption of irrigation technologies, allowing to reduce the gap in terms of economic wellbeing and the long-term sustainability and adaptation to climate change of irrigated areas.
