Does efficient water management matter? physical and economic efficiency of water use in the river basin by Cai, Ximing, Ringler, Claudia, Rosegrant, Mark W.

“…Physical and economic efficiency measures are both useful indicators for water management at the irrigation system and river basin level. However, the relationship between physical efficiency and economic efficiency is not always clear and the values of these measures may indicate different directions for water policy and investments in irrigation. …”

Usefulness of diurnal trunk shrinkage as a water stress indicator in plum trees by Intrigliolo, Diego S., Castel, Juan R.

“…A decrease in plant water status toward the end of the growing season occurred even in the well-irrigated trees, probably reflecting a reduced volume of soil wetted by the drip irrigation system. Thus, for the prediction of Psi(s), different reference equations are required for the fruit-growth and after-harvest phenological periods. …”

Economic valuation of groundwater over-exploitation in the Maghreb by Zaatra, A., Kleftodimos, G., Requier-Desjardins, M., Belhouchette, H.

“…In semi-arid areas, the performance and durability of irrigated systems are often difficult to manage. Understanding agriculture's response to water scarcity, institutional change and policy interventions is important in order to better define the different agricultural development pathways. …”

Weather shocks and rice (Oryza sativa) yield response to fertilizer: Representative field-level evidence from Bangladesh by Takeshima, Hiroyuki, Kishore, Avinash, Kumar, Anjani

“…Notably, in the stochastic LRP model, we find that one standard deviation (1SD) increases in the percentiles of growing degree days (GDD) and high nighttime temperature (HNT) relative to their historical distributions reduce sub‐plateau yield response by 50% or more and yield plateau by up to 0.4 t/ha in Boro and Aman irrigated system. In the Aman rainfed system, 1SD increases in GDD and HNT percentiles reduce sub‐plateau linear responses by roughly 30%. …”

Social learning through water games in the field by Bernal-Escobar, Adriana, Cárdenas, Juan-Camilo, Domenech, Laia, Meinzen-Dick, Ruth S., Sarmiento, Paula J.

“…We conducted a series of educational interventions in two municipal aqueducts in Guasca, Colombia using an irrigation collective action game where five people must decide over contributions to produce water and decide on the sequential allocation of the resource over an irrigation system. We used this setting as a pedagogical tool for understanding the effects of learning over a series of repetitions of these experiments to explore changes in the behaviors and attitudes of rural households in the sample. …”
