“…This finding is consistent with the existing research results [60][61][62]. From the water footprint perspective, the green and blue water footprints of maize were 0.457 and 0.058 m 3 kg −1 , respectively, compared to 0.55 and 0.114 m 3 kg −1 for wheat [63,64]. This reflects the fact that wheat is more responsive to both precipitation and surface water resources than maize.…”

China faces challenges of food security and sustainable agricultural production. However, current studies rarely address the spatial distribution patterns of water consumption and carbon emissions. We studied the irrigation water use efficiency and carbon emission differences of crops in arid areas and their spatial distribution using wheat and maize, two major food crops in the middle reaches of the Heihe River, as examples. Furthermore, we have optimized low-carbon cropping of crops under the multiple objectives of water conservation and economic development. The results show that: (1) The carbon emissions per unit of water consumption for maize are 0.03 × 10−6 t mm−1 and 0.49 × 10−6 t mm−1 for wheat. Irrigation water consumption per unit yield is 515.6 mm t−1 for maize and 426.7 mm t−1 for wheat. (2) The spatial distribution patterns of irrigation water consumption were opposites for maize and wheat. The former has lower irrigation water consumption in the planting area upstream of the Heihe River and higher in the lower reaches. In contrast, the pattern of wheat irrigation is the opposite. (3) After optimizing the cropping mix for both crops, the area planted with wheat should be reduced to 59% of the current size, while maize should be expanded to 104%. The results of the research hold immense importance in guiding the future grain crop planting patterns for water-saving agriculture and low-carbon agriculture development in arid zones worldwide, aligning with the United Nations’ Sustainable Development Goals.

“…Pero no solo lo ambiental, sino se debe de considerar también aspectos culturales, sociales, científicos, económicos, biofísicos y políticos que conduzcan a la integralidad del indicador (Becerra Moreno et al, 2022). De esta manera, el crecimiento económico y poblacional general es uno de los principales impulsores de la huella hídrica ponderada por la escasez de agua para las naciones (Fang et al, 2023).…”

La huella hídrica en los últimos años ha tomado una gran importancia por la escasez del agua dulce por ello se buscó determinar los factores que influyen en la huella hídrica de los estudiantes de Educación de la Universidad Nacional de Ucayali, el trabajo de investigación fue de corte transversal explicativo, donde se aplicó 280 encuestas cuyo instrumento fue el cuestionario sobre la huella hídrica, instrumento que fue elaborado por la Corporación Ambiental Empresarial (CAEM) que nos permitió obtener una base de datos. Los resultados muestran que los factores que influyen son la edad, huella hídrica del alimento (huella indirecta) donde se consideró la frutas, verduras y carnes que consume el estudiante y la huella hídrica de hábitos (a = 0 05; P-valor = 0.00) como es el caso del aseo personal (baño, lavado de manos, dientes), lavado de ropa y vajillas, así llegando a la conclusión que la edad, consumo de alimentos y los hábitos son factores que influyen directamente en la huella hídrica, por lo tanto, se debe de realizar diversas campañas de socialización y uso adecuado del agua, puesto que los valores encontrados de huella hídrica sobrepasan el promedio mundial por persona.

“…This should be attributed to groundwater being pumped, in those regions, at a replenishment-exceeding rate, which contributes to depleting aquifers and rivers: some of the latter run dry for long periods of the year before they reach the sea [ 8 ]. This is done to meet the rising anthropogenic demands and to support international trade, with the consequence that freshwater scarcity is increasingly posing serious threats to global sustainability [ 9 ]. Irrigation is globally recognised as the major purpose of those demands, as it utilises about 70% of water used in society [ 10 , 11 ].…”
