Crop insurance and irrigation behavior: The conditional role of pumping costs

American Journal of Agricultural Economics, EarlyView.
Abstract Excessive water use for irrigation can accelerate the depletion of water resources, undermining agriculture's resilience to weather‐related shocks. Understanding how farmers make water use decisions is essential for developing effective water management policies.

Abrupt shift in elevation-dependent snowmelt contribution in the Central Tibetan Plateau

Journal of Hydrology: Regional Studies
Study region: The headwaters of the Yangtze River Basin on the Tibetan Plateau. Study focus: This study examines whether the elevation dependence of snowmelt-driven runoff in a high-mountain basin can undergo an abrupt shift under recent climate warming.

Farm labor scarcity and its uneven impacts on crop producers in the United States

American Journal of Agricultural Economics, EarlyView.
Abstract This study is the first to evaluate the impacts of farm labor scarcity on producers in the United States across different crop production systems. Between 2002 and 2017, we disentangle the effects of labor scarcity from the impacts of rising commodity demand, technological change, and supply of other inputs on labor market outcomes.

Dalton Medal Lecture: How far can we go in distributed hydrological modelling? [PDF]

, 2001
This paper considers distributed hydrological models in hydrology as an expression of a pragmatic realism. Some of the problems of distributed modelling are discussed including the problem of nonlinearity, the problem of scale, the problem of ...

The Study of the Variation of the Hydrological Regime in a Representative Hydrographic Basin During a Hydrological Cycle [PDF]

Aerul şi Apa: Componente ale Mediului
The study of the variation of the hydrological regime in hydrographic basins is a necessity in the context of climate change. Based on the forecast of flow and level variations, water resources management plans are drawn up.

Sources of uncertainty in hydrological climate impact assessment: a cross-scale study

, 2018
Climate change impacts on water availability and hydrological extremes are major concerns as regards the Sustainable Development Goals. Impacts on hydrology are normally investigated as part of a modelling chain, in which climate projections from ...

Improving access to new technologies: An experiment with Kenyan input sellers

American Journal of Agricultural Economics, EarlyView.
Abstract Agrodealers play a critical role in rural economies, selling essential inputs for agricultural production, stocking new products, and providing farmers with technical advice. However, uncertainty can discourage them from stocking newer, less familiar products, limiting the availability of innovative technologies and leading to market failures ...
