“…This is particularly important when crop production occurs under water scarcity conditions and the risk of overexploitation of water sources or social water conflicts is high (as in the study region; Kuzdas & Wiek, ). To account for the total volume of water withdrawn for crop production, the concept of Crop Water Applied has been used to quantify the total extracted water for the different activities associated with crop production (García Morillo et al, ). Other indicators can also be useful to assess crop irrigation efficiency.…”

Agricultural expansion and intensification is occurring in seasonally dry regions of Central America, while droughts are intensifying due to increasing water demand and climatic change. Empirical measurements of water consumption of major crops in this region are scarce but crucial to assess agricultural water use dynamics in the light of increasing regional water conflicts. We empirically quantify total crop water use (CWU) and water footprints (WFs) of rainfed upland rice (wet season) and groundwater‐irrigated melons (dry season) grown sequentially as a double cropping system, one of the major cropping systems in the seasonally dry province of Guanacaste in northwestern Costa Rica. Data for this study cover 2 years and were measured with a state‐of‐the‐art eddy covariance water and carbon flux station. Upland rice only consumed green water (CWUgreen = 383 L/m2), while melons only consumed blue water (CWUblue = 177 L/m2). Irrigation was found to be 1.5 times larger than the actual melon water consumption, with better irrigation efficiencies than reported for melon farms in Brazil but slightly inferior to farms in Spain. Melon WFblue was 79 m3/t, a much lower value than global and regional estimates reported but similar to values reported for melons produced in Brazil or Spain. Upland rice WFgreen (681 m3/t) was reported for the first time and was proven to be much lower than flood irrigated‐rice WFblue‐green. Our results demonstrated lower overall water demand for upland rice‐melon double crop compared to the two other major monocultures of the region (flood‐irrigated rice and irrigated sugar cane).

“…In agricultural production, the WF can be regarded as a comprehensive indicator of fresh water resources appropriation next to the traditional and restricted measure of water withdrawal. WF could be used to identify water-related hot-spots and to guide actions for better water management, including its use and allocation by supporting decisions on different alternative processes and products [5][6][7][8][9]. The WF of a product is the volume of freshwater used to produce the product measured over the full supply chain [5].…”

Industrial tomatoes are cultivated in about 4000 ha of the Pinios river basin (central Greece), providing significant income to the farmers. In this study, the water footprint (WF) of industrial tomatoes between planting and harvest was estimated in 24 different farms for three consecutive years. The selected farms were representative of the main agro-climatic zones and soil textural classes within the river basin. Green, blue and grey WF calculations were based on datasets of the experimental plots for each farm, including irrigation water volume, meteorological, soil, and crop yield data. The results showed that the WF of tomatoes ranged from 37 to 131 m 3 water/ton tomatoes with an average of 61 m 3 /ton. The WF variation depended mainly on crop yield, local agro-climatic and soil conditions. The green, blue, and grey WF components averaged 13, 27 and 21 m 3 /ton, respectively. The results reveal the importance of WF in understanding how tomato production relates to the sustainable use of freshwater and pollution at local level.

“…During this period, the quasi‐optimum duration of the daily irrigation pulse that satisfies ET c and maintains the soil moisture close to field capacity in the upper 12 cm of soil, varies from 10 to up to 20 min at the end of the stage. However, a significant number of farmers apply water in pulses of 30–40 min (García Morillo et al ., , b).…”

“…Furthermore, the most common irrigation emitters used are 1‐year‐duration low‐density polyethylene tapes, which are not the most suitable system for irrigating crops by pulsing, a process that is critical in these sandy soils. System malfunctioning is common in the region as the irrigation units are usually too large, so most of the emitters do not work within the right pressure range (García Morillo et al ., ). To exacerbate the situation, irrigation systems management is based mainly on farmer experience instead of relying on objective methods using agro‐climatic and soil data.…”

“…To exacerbate the situation, irrigation systems management is based mainly on farmer experience instead of relying on objective methods using agro‐climatic and soil data. Pulse duration shows a wide variability, indicating the lack of technical information about both the irrigation requirements and how to apply them (García Morillo et al ., ). To reduce the inaccuracy of current irrigation management at farm level, precision irrigation systems based on sound scientific procedures are currently being developed (García Morillo et al ., ).…”

Estimation of the optimum irrigation pulse duration and frequency is critical for any crop, and especially important in the typical sandy soil existing in the strawberry production area in south‐west Spain. Irrigation scheduling has been carried out using the numerical model Hydrus‐2D. The model has been calibrated with data from a soil tank experiment carried out in the laboratory. The optimum pulse duration has been estimated in three different crop stages, and has been compared with the irrigation scheduling recorded in the field, estimating the potential water saving in strawberry production in Huelva. The optimum irrigation pulse duration starts with an irrigation time of 10 min that should be increased until a maximum of 1 h, divided into several pulses. Applying rop water needs in several shorter pulses is a strategy highly recommended especially in the typical sandy soil, with very low water retention capacity. It has been shown that current management is disproportionate, maintaining the moisture content out of reach of the roots. Therefore, it is advisable to check the current irrigation management, so that the irrigation matches crop water requirements, maintaining sufficient moisture within the upper 30–40 cm of soil, avoiding water losses by percolation and groundwater pollution.
