Investments in the physical infrastructure, human capital, and institutions needed for water resources management have been noteworthy in the development of most civilizations. These investments affect the economy in two distinct ways: (i) by improving the factor productivity of water in multiple economic sectors, especially those that are water intensive such as agriculture and energy and (ii) by reducing acute and chronic harmful effects of water-related hazards like floods, droughts, and water-related diseases. The need for capital investment to mitigate risks and promote economic growth is widely acknowledged, but prior conceptual work on the relationship between water-related investments and economic growth has focused on the productive and harmful roles of water in the economy independently. Here the two influences are combined using a simple, dynamical systems model of water-related investment, risk, and growth. In cases where initial water security is low, initial investment in water-related assets enables growth. Without such investment, losses due to water-related hazards exert a drag on economic growth and may create a poverty trap. The presence and location of the poverty trap is context-specific and depends on the exposure of productive water-related assets to water-related risk. Exogenous changes in water-related risk can potentially push an economy away from a growth path toward a poverty trap. Our investigation shows that an inverted-U-shaped investment relation between the level of investment in water security and the current level of water security leads to faster rates of growth than the alternatives that we consider here, and that this relation is responsible for the "S"-curve that is posited in the literature. These results illustrate the importance of accounting for environmental and health risks in economic models and offer insights for the design of robust policies for investment in water-related productive assets to manage risk, in the face of environmental change.

Investments in modernizing irrigation infrastructure are key to enhance water security for agriculture. However, outcomes of investments are insufficiently understood, limiting the future design of interventions. This article applies a fixed effects regression model to test whether modernization of irrigation systems in Madhya Pradesh leads to improvements in district-level yields and protection of yields against sub-basin rainfall variability. Findings suggest that investments fail to improve yields in districts with deficient rainfall and fail to buffer crops against monsoon variability, compared to control districts with no investments. Interventions should be designed to respond to the complexities of sub-basin rainfall variability.

Investments to rehabilitate irrigation infrastructure aim to enhance climate resilience and improve farmers' livelihoods in the face of hydrological risks. Studies seeking to assess the impacts from investments in irrigation primarily focus on yield and income-related poverty measures. This approach provides an incomplete picture of the distributional implications of investments, such as the impact of rehabilitated irrigation infrastructure on the subjective well-being of farmers. Drawing on data from 707 farmers in Madhya Pradesh, India, we explore whether investments to rehabilitate irrigation infrastructure are associated with changes in subjective well-being among smallholders. Our findings show a positive relationship between farmers with access to rehabilitated surface irrigation and well-being improvements. Results reveal that farmers in areas with rehabilitated irrigation canals experience improvements in subjective well-being which are 20%–30% higher in comparison to farmers in areas without rehabilitated canals. When results are disaggregated, we find a larger positive effect on well-being for farmers in deficient-rainfall areas compared to average- or high-rainfall areas. The integration of contextual factors related to subjective well-being into future assessments of infrastructure investments in India can enhance knowledge of the multidimensional benefits of canal irrigation among diverse farming groups facing differing degrees of hydrological risk.
