摘要
A major challenge for agricultural water management (AWM) in the 21st century is to feed a growing population in the face of increasing intersectoral resource competition, evolving diets, degradation, pandemics, geopolitical conflicts and climate change. This has to be achieved within the planetary boundaries and without compromising the livelihood and environmental (ecosystem) objectives linked to water, including provisioning, supporting and regulating services. This paper uses a systems and nexus lens to unravel the centrality and complexities in AWM, with particular emphasis on the interconnected dimensions and objectives of AWM, as well as its practices and technologies. AWM exists beyond water and food with linkages to human and environmental well-being. AWM needs to catalyse transformation and integrate approaches across systems, users and scales to meet its objectives in a changing climate. It must provide perspectives beyond productivity, managing water risks and safeguarding food security - as important as these are - and integrate our understanding of the interconnected climate, land, water, food and ecosystems to address planetary health outcomes. By doing so, AWM could catalyse contextualised, equitable, innovative solutions that acknowledge local socio-economic and institutional structures and limitations while catalysing sustainable development and climate resilience. L'un des principaux d & eacute;fis de la gestion de l'eau agricole (GEA) au XXIe si & egrave;cle est de nourrir une population croissante dans un contexte de concurrence intersectorielle croissante pour les ressources, d'& eacute;volution des r & eacute;gimes alimentaires, de d & eacute;gradation, de pand & eacute;mies, de conflits g & eacute;opolitiques et de changement climatique. Cet objectif doit & ecirc;tre atteint dans les limites de la plan & egrave;te et sans compromettre les objectifs de subsistance et environnementaux (& eacute;cosyst & egrave;mes) li & eacute;s & agrave; l'eau, notamment les services d'approvisionnement, de soutien et de r & egrave;glementation. Cet article utilise une perspective syst & eacute;mique et de liens pour d & eacute;m & ecirc;ler la centralit & eacute; et les complexit & eacute;s de la GEA, en mettant l'accent sur les dimensions et les objectifs interconnect & eacute;s de la GEA, ainsi que sur ses pratiques et ses technologies. La GEA existe au-del & agrave; de l'eau et de l'alimentation et poss & egrave;de des liens avec le bien-& ecirc;tre humain et environnemental. La GEA doit catalyser la transformation et int & eacute;grer des approches entre les syst & egrave;mes, les utilisateurs et les & eacute;chelles afin d'atteindre ses objectifs dans un climat en & eacute;volution. Elle doit offrir des perspectives au-del & agrave; de la productivit & eacute;, de la gestion des risques li & eacute;s & agrave; l'eau et de la sauvegarde de la s & eacute;curit & eacute; alimentaire - aussi importantes soient-elles - et int & eacute;grer notre compr & eacute;hension des liens entre le climat, la terre, l'eau, l'alimentation et les & eacute;cosyst & egrave;mes pour r & eacute;pondre aux r & eacute;sultats en mati & egrave;re de sant & eacute; plan & eacute;taire. Ce faisant, la GEA pourrait catalyser des solutions contextualis & eacute;es, & eacute;quitables et innovantes qui reconnaissent les structures et les limites socio-& eacute;conomiques et institutionnelles locales tout en catalysant le d & eacute;veloppement durable et la r & eacute;sistance au climat.
