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

open access: yesAgribusiness, 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 ...

Comparison of the Efficiency of Linear and Non-linear Time Series Models in Simulation and Prediction of Reference Evapotranspiration [PDF]

open access: yesنشریه جغرافیا و برنامه‌ریزی, 2018
Reference evapotranspiration (ET0) is one of the important factors to determine crop water requirement. Accurate estimation of reference evapotranspiration (ET0) value has a very important role in water resources management and optimizing agricultural ...

The Global Crop Water Model (GCWM) : documentation and first results for irrigated crops [PDF]

open access: yes, 2008
A new global crop water model was developed to compute blue (irrigation) water requirements and crop evapotranspiration from green (precipitation) water at a spatial resolution of 5 arc minutes by 5 arc minutes for 26 different crop classes. The model is

Prediction Accuracy for Projectwide Evapotranspiration Using Crop Coefficients and Reference Evapotranspiration

open access: yesJournal of Irrigation and Drainage Engineering, 2005
The Imperial Irrigation District is a large irrigation project in the western United States having a unique hydrogeologic structure such that only small amounts of deep percolation leave the project directly as subsurface flows. This structure is conducive to relatively accurate application of a surface water balance to the district, enabling the ...

Reference crop evapotranspiration derived from geo-stationary satellite imagery: a case study for the Fogera flood plain, NW-Ethiopia and the Jordan Valley, Jordan [PDF]

open access: yes
First results are shown of a project aiming to estimate daily values of reference crop evapotranspiration ET0 from geo-stationary satellite imagery. In particular, for Woreta, a site in the Ethiopian highland at an elevation of about 1800 m, we tested a ...

Cutting Through the Green: A Case for Grassland Archaeology Using UAV Multispectral Data

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Advances in low‐altitude remote sensing are needed to improve the effectiveness of archaeological prospection in the Netherlands. The geomorphological situation and land use history make applying various remote sensing and geophysical technologies particularly challenging.

Restoring Trust: Rebuilding the Forest Carbon Credit System Through Scientific Rigor

open access: yesBiological Diversity, EarlyView.
ABSTRACT As pivotal nature‐based climate solutions (NbCS), forests are increasingly recognized for their climate mitigation potential. However, this potential is undermined by fundamental flaws in current carbon credit systems. Our analysis identifies four interconnected systemic challenges: (1) subjective additionality assessments arising from ...
