“…La producción de maíz depende en gran medida de fertilizantes sintéticos, diesel, electricidad de origen fósil y demandan grandes cantidades de agua de riego debido al uso extensivo de métodos de riego por surcos de baja eficiencia. Estas consideraciones plantean preocupaciones sobre la sostenibilidad de los métodos agrícolas convencionales utilizados actualmente para el cultivo de este grano (Juárez & Sheinbaum, 2020). En 2016 se destinaron 7,76 millones de hectáreas a la producción de maíz (temporal y riego), de estas 75,59% se encuentran mecanizadas, 65,06% no cuentan con tecnología aplicada a la sanidad vegetal, y 30,16% de la superficie sembrada tuvo asistencia técnica (SAGARPA, 2017).…”

The cultivation and production of grain maize constitute an important opportunity to promote the socio-economic and agricultural development of the communities of Mexico. According to the National Agricultural Planning 2017-2030 related to corn grain proposed by the federal government through the Secretariat of Agriculture and Rural Development (SADER); pointed as a producing region with production potential to the states of Sinaloa, Nayarit, and Jalisco. Grouped by the territorial structure that produces corn grain that predominates in this region. Same that contributed 35% of the national production of this grain in 2021. In order to find significant differences in the yield of corn in water modalities (irrigation and temporal), the analysis of variances for the proposed case of the states that make up the Western Territorial Region is addressed. With a temporality from 2008 to 2018. According to the analysis of variance of a ten-year cohort, it is concluded that in the Western Territory Region it was observed that the average yield of irrigated grain maize production is 1.6 times greater than that of temporary. In the case of Sinaloa, it corresponds to 5.7, in Jalisco to 1.3, and in Nayarit to 1.6 times greater than the irrigation than the storm. This corresponds to and justifies a policy that supports the optimal use of water resources, through irrigation channels or hunting that includes benefits for small producers and not only in agroextractivism.

“…The increase in grain maize productivity of the states located in category C was because they managed to make their field yields more efficient, since their surfaces planted decreased. Two factors explained the increase in the field yields: use of improved maize seeds [11] and use of irrigation [39], whether in their totality as in the case of Sinaloa (main maize producer in Mexico) or with irrigation that aids the summer rains (rainfed) in Jalisco (second producer) and Estado de México (third producer).…”

Mexico depends on maize imports to satisfy its national demand. The use of native maize varieties among subsistence farmers can help to reduce the cereal’s imports. However, the agricultural policy in Mexico to improve the productivity per hectare has centered on the use of improved varieties; among them, the transgenic variety. In this study, the maize productivity in Mexico from 1983 to 2018 was analyzed to determine the influence of agricultural policies in the sector, and the factors that condition the adoption of transgenic maize. It was found that the agricultural policy improved the productivity of those regions with irrigation; however, for rainfed regions, the expected technological changes were not achieved because the ancestral tradition in cultivation, associated with the greater variety of native maize and to a larger indigenous population, was stronger. The adoption of transgenic maize also had low significance in the rainfed regions, since the increase in field yields is not economically profitable with regards to the increase in production costs. Therefore, the agricultural policy to increase productivity ought to be directed at the protection of subsistence farmers, revaluing the use of native varieties that have shown higher resilience to technological and environmental changes.

“…Therefore, the primary objective of this study is to examine the correlation between agricultural water usage efficiency and energy poverty, with the aim of identifying various ways to align these two Sustainable Development Goals (SDGs). In the agricultural sector and rural areas, these two goals are inextricably linked, as there is a strong connection between energy and irrigation [1][2][3][4][5][6] .…”

The research attention is increasingly directed towards the effective integration of the 17 United Nations Sustainable Development Goals (SDGs) within the limitations of the real world and amidst intersectoral conflicts. In light of the inextricable relationship between irrigation and energy, the objective of this study is to identify potential avenues for achieving the SDG6 and SDG7 goals of enhancing water use efficiency in agriculture and eradicating energy poverty, respectively. Utilizing data from 30 Chinese provinces from 2002 to 2017, this study explores the dynamic influence of energy poverty on agricultural water efficiency with a system generalized method of moments methodology. The findings suggest that energy poverty may greatly reduce agricultural water efficiency. The heterogeneity study shows that when agricultural water efficiency grows, the negative impacts of energy poverty continue to fade. Based on an assessment of various processes, results suggest that non-farm employment and cropping structure modification is a prominent conduit via which energy poverty negatively influences agricultural water efficiency.
