The world has pledged to protect 30 percent of its land and waters by 2030 to halt the rapid deterioration of critical ecosystems. We summarize the state of knowledge about the impacts of protected area policies, with a focus on deforestation and vegetation cover. We discuss critical issues...

The European Union designates 26% of its landmass as a protected area, limiting economic development to favor biodiversity. This paper uses the staggered introduction of protected-area policies between 1985 and 2020 to study the selection of land for protection and the causal effect of...

Tile drainage was first demonstrated in the United States in 1835 as a method to adapt agriculture to excessive water in soils. Subsequently, innovations in coordinated drainage enterprises, engineering, and tile manufacture led to drainage over large portions of the U.S. Midwest and Southeast....

Irrigation in the Eastern US receives little attention compared to the West, but farmers in humid states of the US, traditionally reliant on rainfall, have more than tripled irrigation since 1978. We examine this trend in Illinois where there has been a nearly threefold increase in center pivot...

We study a fundamental institution in many societies: the structure of property rights over land. Across societies, communal land rights have been more common than private land rights. We test the hypothesis that longer fallow requirements - the time needed to leave land uncultivated to restore...

We provide novel evidence that large-scale irrigation heterogeneously shifts the temperature distribution towards cooler temperatures during the months of the growing season relative to the rest of the year. We employ a triple-difference estimator using a 59-year-long panel of weather records...

The expansion in farm size is an important contributor to agricultural productivity in developed countries, but the reallocation process is hindered in less developed economies. How do distortions to factor reallocation affect farm dynamics and agricultural productivity? We develop a model of...

Land market incompleteness is argued to have pervasive effects in Sub-Saharan Africa, including on agricultural efficiency, equity, and structural transformation. Yet experimental evidence on land market participation is virtually non-existent. We randomly allocate subsidies for agricultural...

Crop farmers have few short-run options for reducing downside production risk from changes in drought frequency and intensity due to ongoing climate change. However, one recently available option is drought-tolerant (DT) varieties. We determine how recent drought exposure, drought risk, and...

Global climate change is already impacting water resources and, in many areas, reducing the amount of water available for drinking, sanitation, and agriculture. Water conservation can be a means to mitigate the economic damages associated with water scarcity, including scarcity arising from...
