The United Nations Food Systems Summit aimed to chart a path toward transforming food systems toward achieving the Sustainable Development Goals. Despite the essentiality of water for food systems, however, the Summit has not sufficiently considered the role of water for food systems transformation. This focus is even more important due to rapidly worsening climate change and its pervasive impacts on food systems that are mediated through water. To avoid that water “breaks” food systems, key food systems actors should 1) Strengthen efforts to retain water-dependent ecosystems, their functions and services; 2) Improve agricultural water management; 3) Reduce water and food losses beyond the farmgate; 4) Coordinate water with nutrition and health interventions; 5) Increase the environmental sustainability of food systems; 6) Explicitly address social inequities; and 7) Improve data quality and monitoring for water-food system linkages.

Distefano, T. | Isaza, A Saldarriaga | Muñoz, E. | Builes, T.
Poorer countries often face a severe trade-off: the need to improve socio-economic conditions is hard to balance with the maintenance of key ecological processes. As a case study, we select Colombia, a Latin American country with almost 10% of its inhabitants living in extreme poverty. We elaborate a water–food–labour (WFL) nexus grounded on a sub-national Environmentally Extended Input–Output (EEIO) analysis to assess the virtual water trade (VWT) and virtual informal labour (VIL) flows across administrative departments and economic sectors related to domestic trade. The main results are the following: high cross-departmental resource interdependence both in terms of VWT and VIL, rich departments highly depend on the resources of their neighbouring trading partners, extreme poverty conditions shown by economically isolated departments, and considerable income inequality in the food production sectors. Moreover, departments that are net exporters of virtual water suffer from water stress that might be exacerbated by future high rainfall variability due to climate change. These results suggest that strategies to attain sustainable development goals (SDGs) must deal with the biophysical constraints and the economic and political feasibility of the proposed solutions. In this vein, we argue that a holistic framework, grounded on quantitative analyses, is necessary to support informed policy decisions for the simultaneous achievement of multiple (possibly contrasting) goals. Moreover, severe spatial imbalances call for local policy responses coordinated at the national level.

Water management is one of the key elements in any farming system. In South-West Bangladesh, canals,locally referred to as khals, are crucial in this respect; they transport water to the fields and ponds, but also enable drainage. In this area, sedimentation limits the water-carrying capacity of rivers and canals. That is why continuous re-excavation of canals and rivers is important to maintain agricultural production and livelihoods.This report documents a pilot of canal re-excavation for micro-watershed rejuvenation, under the SaFaL-2 project in South-West Bangladesh. Six recently rejuvenated micro-watersheds, three in Khulna district and three in Satkhira district, have been visited and studied. The links between water management, food systems and value chains are discussed, based on an agriculture and food system approach taking the water system into account. Here it is identified, among other things, that scaling is an important characteristic of deltas,which should be considered to ensure that the interventions at micro-watershed level match developments and plans at a larger spatial level | Waterbeheer is een van de sleutelelementen in elk landbouwsysteem. In Zuidwest-Bangladesh zijn kanalen,plaatselijk khals genoemd, in dit opzicht van cruciaal belang; zij transporteren water naar de velden en vijvers,maar maken ook drainage mogelijk. In dit gebied beperkt sedimentatie de draagkracht van rivieren en kanalen. Daarom is voortdurende heruitgraving van kanalen en rivieren van belang om de landbouwproductie en de kostwinning in stand te houden. Dit rapport documenteert een proefproject voor de heruitgraving van kanalen in het kader van het SaFaL-2-project in het zuidwesten van Bangladesh. Zes onlangs gerehabiliteerde micro-stroomgebieden, drie in het district Khulna en drie in het district Satkhira, zijn bezocht en bestudeerd. Als reflectie worden de verbanden tussen waterbeheer, voedselsystemen en waardeketens beschreven, aan de hand van een landbouw- en voedselsysteembenadering die rekening houdt met het watersysteem. Daarin komt onder meer naar voren dat de interactie tussen ruimtelijke schalen een belangrijk kenmerk van delta’s is,waarmee rekening moet worden gehouden om ervoor te zorgen dat de ingrepen op het niveau van de micro-stroomgebieden aansluiten bij ontwikkelingen en plannen op een groter ruimtelijk niveau.

Water rights trading is an important way to solve the problem of water shortage by market mechanism. The allocation of water rights among ecological water, energy water, and grain planting water are the basis of the regional water rights trade. In this paper, the concept of coordinated development of water–ecology–energy–food is proposed. We build a water rights allocation model with fairness, efficiency, and coordinated development as the goal, to achieve water security for various industries. Taking Yinchuan city as an example, the results showed that compared with the current water rights the water rights of life increased by 1.07%, the water rights of ecology increased by 1.85%, the water rights of energy industry decreased by 1.09%, the water rights of food planting decreased by 3.27%, the water rights of other agriculture increased by 0.83%, and the water rights of the general industry increased by 0.65%. After the allocation of water rights, the cooperativity of water–ecology–energy–food increased by 7.56%, and the total value of water resources in various industries increased by 2.31 × 10⁸ CNY. A new water rights allocation model is developed in this paper, which can provide a reference for the allocation of water rights among regional industries.
