Sustainable Water Management in Horticulture: Problems, Premises, and Promises

Horticulturae, Journal Year: 2024, Volume and Issue: 10(9), P. 951 - 951

Published: Sept. 6, 2024

Water is crucial for enduring horticultural productivity, but high water-use requirements and declining water supplies with the changing climate challenge economic viability, environmental sustainability, social justice. While scholarly literature pertaining to management in horticulture abounds, knowledge of practices technologies that optimize use scarce. Here, we review scientific relating crops, impacts on resources, opportunities improving water- transpiration-use efficiency. We find crops vary widely, depending crop type, development stage, agroecological region, investigations hitherto have primarily been superficial. Expansion sector has depleted polluted resources via overextraction agrochemical contamination, extent significance such issues are not well quantified. contend innovative irrigation can improve tactical mitigate impacts. Nature-based solutions horticulture—mulching, organic amendments, hydrogels, like—alleviate needs, information their effectiveness across production systems regions limited. Novel recycled sources (e.g., treated wastewater, desalination) would seem promising avenues reducing dependence natural detrimental human health trade-offs if managed. Irrigation including partial root-zone drying regulated deficit evoke remarkable improvements efficiency, require significant experience efficient implementation. More advanced applications, IoT AI sensors, big data, data analytics, digital twins), demonstrable potential supporting smart (focused scheduling) precision (improving spatial distribution). adoption sustainability increasing, application within industry as a whole remains its infancy.

Future Climate Trends in the Wine-Growing Regions of the Western Cape of South Africa

Atmosphere, Journal Year: 2025, Volume and Issue: 16(2), P. 227 - 227

Published: Feb. 18, 2025

The Western Cape province is among the best wine-producing regions; however, has been facing environmental challenges due to rapidly changing climate. This study analyses projected changes in temperature and precipitation patterns across seven districts using high-resolution regional climate model (RCM) simulations from CORDEX-Africa framework. highlight spatial variability variable topography microclimates within wherein conditions are over selected regions. Olifants River experience most substantial increases—greater than 5 °C—under very high baseline emission scenario at end of century, while regions closer coast, such as Agulhas, moderate both changes. indicate a strong drying trend, especially that farther south coast. results vulnerability vinicultural practices change; therefore, this can be used provide stakeholders with information needed so they adapt wine
