Evaluation of SIMETAW Model For Simulation of Meteorological Parameters and Potential Evapotranspiration in Four Different Climates [PDF]

علوم و مهندسی آبیاری, 2017
Different models are provided for estimation of evapotranspiration that the main difference between them is the number of meteorological parameters needed,but due to the lake of the reliable long-term data in some stations,use of model with little data ...

Assessing Crop Coefficients for Natural Vegetated Areas Using Satellite Data and Eddy Covariance Stations

Sensors, 2017
The Food and Agricultural Organization (FAO) method for potential evapotranspiration assessment is based on the crop coefficient, which allows one to relate the reference evapotranspiration of well irrigated grass to the potential evapotranspiration of ...

An Application of Improved MODIS-Based Potential Evapotranspiration Estimates in a Humid Tropic Brantas Watershed—Implications for Agricultural Water Management

ISPRS International Journal of Geo-Information, 2022
The reliance on native MODIS-16 PET potential evapotranspiration (PET) in scarce-data-driven areas is growing in support among ecohydrological studies, yet information about its performance is limited or unknown as validation studies are mostly ...

Agrivoltaics Over Berries in Chile: Potential for Clean Energy Generation and Climate Change Adaption

AgriVoltaics Conference Proceedings
Agrivoltaics (AV), the concept of installing photovoltaic (PV) panels on agricultural land, enabling a dual use of the surface, has the potential to foster renewable energy expansion without land use conflict and to protect water from evapotranspiration.

The Power of Unity: Collective Action and Smallholder Agricultural Performance in West Africa

Agribusiness, EarlyView.
ABSTRACT We analyze the impact of collective action through farmer‐based organizations (FBOs) on smallholders' farm performance and income inequality in Ghana, Benin, The Gambia, and Mali. We find that FBO membership increases cereal yield in Ghana and The Gambia, legume yield in Mali, ruminant numbers in Benin and The Gambia, and total farm income in ...
