This study explores the water consumption and greenhouse gas (GHG) emissions in Yarkand River Basin, focusing on their dynamic interactions across industrial sectors. Utilizing environmental input–output analysis (IOA), CROPWAT model, life cycle assessment (LCA), we quantified historical evolution of physical virtual cycles relation to water–carbon nexus. Our findings reveal that planting industry, particularly production export-oriented, water-intensive crops like cotton, significantly contributes both blue green consumption, exacerbating regional scarcity. The persistent external market demand drives this over-extraction, further strained by basin’s limited retention capabilities. Although advancements have been made reducing per-unit footprint crops, total continues rise due agricultural expansion, intensifying pressure resources. Additionally, GHG surged, driven increased electricity heavy fertilizer use, escalating soil N2O emissions. In light these challenges, our research underscores critical need for integrated resource management strategies align with sustainable development goals. By promoting efficient allocation within sector diversifying crop structures downstream, can enhance ecosystem resilience reduce degradation. Furthermore, advancement value-added processing implementation innovative conservation technologies are essential fostering economic sustainability. These not only mitigate impacts associated practices but also strengthen region’s adaptive capacity face climate change fluctuating demands. contribute broader discourse practices, emphasizing interconnectedness management, resilience, viability arid regions.

Avocado Water Footprint for Two Municipalities in Michoacán, Mexico: A Research of the Blue and Green WF

Agriculture, Journal Year: 2024, Volume and Issue: 14(7), P. 981 - 981

Published: June 24, 2024

The Water Footprint (WF) is an indicator used to determine good practices for efficiently using water in human activities. This work evaluates the green (rainfed) and blue (irrigation) footprint of avocado cultivation municipalities Acuitzio (2012–2016) Morelia (2016–2020) Michoacán, Mexico. Likewise, stress irrigation use analyzed, linking WF with volumes concessions agricultural use. results revealed that mean 1292.49 m3/ton, 689.23 m3/ton. In Morelia, 582.97 711.74 production irrigated 7963.62 (ton/year), 8547.76 which allows us project that, Acuitzio, crop requires annual 5,046,610.69 m3, while requirement 6,029,920.59 m3. average volume 3,357,782.93 demand 149.27%. situation shows this municipality since consumption exceeds available resources. For 11,418,745.40 as a 53.18%, can put supply resource other crops at risk.
