This paper discusses a study of household land-use and livelihood strategies in the Toluca Metropolitan Area, west of Mexico City, a traditional maize-growing region that has experienced rapid urban growth. It shows that maize is being abandoned
to some extent as producers age and non-farm income sources surge. At the same time, some maize still persists for tradition and security as non-farm income is often volatile. The results reflect a persistence of maize in peri-urban areas of central Mexico

Based on the cross-entropy theory, a spatial production allocation model (SPAM) has been developed for presenting spatio-temporal dynamics of maize cropping system in Northeast China during 1980–2010, at the pixel level. The AA. further explored
spatio-temporal variations of maize with latitude, longitude, and elevation. Discussion of the results. It is highlighted that maize planting density increased gradually to a moderately high level over the investigated period, which reflected the trend
of aggregation of maize cultivation driven by market demand.

the study period, the most serious being in the Beijing-Tianjin-Tangshan metropolitan agglomerate. 2) The irrigation water resources demanded by the winter wheat-summer maize double cropping system ranged from 400 mm to 530 mm, while those demanded
by the spring maize single cropping system ranged only from 160 mm to 210 mm. 3) The water resources conserved as a result of the winter wheat sown area shrinkage during the study period were about 15.96×108 m3/a, accounting for 27.85% of those provided
This article examines agrobiodiversity, indigenous knowledge, and a feminist political ecology of sorghum and finger millet in Northern Malawi. First, it suggests that sorghum almost disappeared due to a combination of maize promotion, male
migration, and pest problems. Second, that an upsurge of tobacco production, in part due to neoliberal policies, combined with gender dynamics that favor maize are reducing finger millet production. It concludes that efforts to improve social resilience
