The Scientific World Journal, 2012 Crop water requirement is essential for agricultural water management, which is usually available for crop growing stages. However, crop water requirement values of monthly or weekly scales are more useful for water management.

Egyptian Journal of Remote Sensing and Space Sciences, 2012 Crop water requirements are represented by the actual crop evapotranspiration. Estimation of crop evapotranspiration (ETc) and crop coefficient using remote-sensing data is essential for planning the irrigation water use in arid and semiarid regions ...

Reference evapotranspiration of screenhouse‐grown crops
Actas del III Workshop en Investigación Agroalimentaria. WiA 3.1The reference evapotranspiration Eref was measured under three screenhouses and compared to outside Eref. The reduction with respect to outside Eref was quantified by means of two factors, rad and adv. rad was found to depend linearly on transmittance (), and adv on wind ratio (). A model was proposed for screenhouse Eref based on

, 2009 Evapotranspiration (ET) from the wetland of the Yellow River Delta (YRD) is one of the important components in the water cycle, which represents the water consumption by the plants and evaporation from the water and the non-vegetated surfaces.

Temperature Sensitivity and Adaptation of Cereal Yields: Empirical Evidence From Italy
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT This paper investigates the evolving temperature sensitivity and climate adaptation of cereal yields in Italy from 1952 to 2023, using province‐level data for maize, common wheat, and durum wheat. Employing panel data econometric methods, we estimate yield responses to heat exposure, changes in sensitivity over time, and adaptation to climate ...

Evapotranspiration estimates for water balance scheduling in the UK [PDF]
, 1996 This paper compares the use of different methods for estimating reference evapotranspiration (ETo) for irrigation scheduling in the UK. Methods include use of long-term averages, daily weather data and evaporimeters. The results from a single trial in

Why Didn't I Get a Payout? Understanding Farmer Choices, Index Insurance, and Basis Risk
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Index insurance, while heralded as a potential solution to alleviate poverty and food insecurity among agricultural households, has its own set of challenges, notably basis risk. Basis risk is the discrepancy between the insurance payout and losses incurred, posing a significant deterrent to the adoption of index insurance.

Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Increased frequency of extreme weather events, particularly droughts, threatens grassland farming by destabilizing yields and farms' economic viability. We examine, theoretically and through numerical simulations, how sown plant diversity (natural insurance) influences the attractiveness of indemnity and drought index insurance (formal ...
