“…This has a direct effect on water sacrifice and greenhouse gas emissions [51]. Niu et al's research results show that the influence coefficient of cropping type on the agricultural carbon footprint can reach 0.31, which is the highest among various influencing factors [52]. The willingness of farmers to be active is very important for the actual agricultural emission reduction actions.…”

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.

La actividad agrícola es un detonante del desarrollo económico en Sinaloa, México; el maíz es el cultivo más destacado; sin embargo, los procesos productivos están lejos del desarrollo sostenible. Por lo tanto, el objetivo es analizar los aspectos inherentes a la intensificación del cultivo del maíz desde la perspectiva del desarrollo sustentable, examinando los contextos económico, social y ambiental del proceso del cultivo del maíz a nivel global, nacional y del estado de Sinaloa. Esta investigación fue diseñada como un estudio descriptivo-explicativo con un enfoque cualitativo. Los resultados indican que existen varios desafíos que enfrentan los agricultores al encaminar procesos agrícolas hacia el desarrollo sostenible, tales como falta de información, falta de innovación, aversión al riesgo y resistencia al cambio; a pesar de esto, las consecuencias de aplicar prácticas agrícolas sustentables son positivas, generando mayor producción y cuidado de los recursos naturales. A pesar de los efectos que la agricultura ha tenido sobre el medio ambiente, cambiar el enfoque y reestructurar la producción de maíz con un enfoque de desarrollo sostenible es el camino a seguir para asegurar que esta actividad pueda seguir desarrollándose a lo largo de los años.

“…The global agriculture sector faces an unprecedented challenge in the form of climate change, marked by rising temperatures, unpredictable precipitation patterns, and the increasing concentration of greenhouse gases (GHGs) in the atmosphere. As agriculture both contributes to and is vulnerable to climate change, there is a pressing need to explore sustainable practices that not only ensure food security but also mitigate environmental impacts [1][2][3].…”

The complex ramifications of global climate change, which is caused by heightened concentrations of greenhouse gases in the Earth’s atmosphere, are deeply concerning. Addressing this crisis necessitates the immediate implementation of adaptive mitigation strategies, especially within the agricultural sector. In this context, this study aimed to assess how the supply of nitrogen (N) (0, 70, 140, and 210 kg N ha−1) in the forms of ammonium nitrate and urea affects the agronomic performance, food quality, greenhouse gas emissions (GHG), and carbon footprint of potato plants. The examined hypothesis was that by precisely calibrating N doses alongside appropriate sourcing, over-fertilization in potato cultivation can be mitigated. A decline in stomatal conductance and net photosynthetic rate disturbs physiological mechanisms, reflecting in biomass production. Application of 136 kg N ha−1 as urea showed a remarkable yield increase compared to other doses and sources. The highest nitrate content in potato tubers was achieved at 210 kg N ha−1 for both sources, not exceeding the limit (200 mg kg−1 of fresh mass) recommended for human consumption. The lowest carbon footprint was obtained when 70 kg N ha−1 was applied, around 41% and 26% lower than when 210 kg N ha−1 and 140 kg N ha−1 were applied, respectively. The results demonstrated that over-fertilization not only worsened the yield and tuber quality of potato plants, but also increased greenhouse gas emissions. This information is valuable for establishing an effective fertilization program for the potato crop and reducing carbon footprint.
