“…The lack of water infrastructure to convey freshwater to the farmland, coupled with the high cost of wastewater treatment before reuse have been the limiting factors promoting the use of untreated wastewater, especially for irrigation in rural settings, without considering any form of pathogenic contamination (Hanjra et al, 2012b; Ajibade et al, 2021a , b). The reuse of treated wastewater in agriculture reduces freshwater pumping and fertilizer usages; consequently promoting the reduction of the water footprint of food production on the environment while achieving higher yields under reduced cost and carbon footprint (Hanjra et al, 2012b; Adelodun and Choi, 2020 , Odey et al, 2021b ). The reuse of wastewater, rather indiscriminate discharge into the environment contributes immensely to urban food security while improving the urban environment ( Goala et al, 2021 ).…”

“…It has become an important tool in waste management because it allows comparing all inputs, stocks, and outputs of a process [32]. Adelodun and Choi [33] recently used the same methodological approach to study food waste along the supply chain in Korea.…”

“…After quantifying FLW for each step of the FSC, the conversion factors were applied to determine the edible mass. The waste percentages and the conversion factors calculated by Gustavsson et al [13] have also been used in other studies on FLW (see Oelofse and Nahman [31]; Adelodun and Choi [33]; Reutter et al [36]).…”

“…Therefore, the impact of trading standards, aesthetic requirements and food safety regulations needs to be studied. Future studies also could focus on the land and water footprints associated with food losses as done for other countries, such as Brazil [54], Korea [33], and India [55]. This research line could focus on Peru's exportoriented supply chains considering, for instance, the Andean crops associated with rapid land-use change [56] or horticultural export chains [57].…”

The quantification of food losses and waste (FLW) has become a research hotspot in the last decade, but little work has been done to have food waste data in Latin American countries. This paper contributes to addressing this knowledge gap by examining the magnitude of FLW along the whole food supply chain (FSC) in Peru. The methodological approach was based on the top-down mass flow analysis at all steps of the FSC for the 2007–2017 period (most recently available data), including different food commodity groups (CGs), such as cereals, roots and tubers, oil seeds and pulses, fruits, vegetables, meat, fish and seafood, and milk. Results show an annual average of FLW of 12.8 million tonnes, which represents 47.76% of the national food supply. Regarding per capita quantities, the average amount of FLW was 426.56 kg per year when considering the entire FSC, and 67.34 kg per year when considering only the consumption step. This study suggests which steps of the FSC and CGs are the most promising targets for FLW reduction strategies in Peru.

“…For instance, South Korea, one of the industrialized countries in the Asian continent with low ratings on climate policy [5], has continued to experience severe and frequent drought periods, with water scarcity problems which have continued to impact the existing fragile agriculture and crop production system [6,7]. Accordingly, the freshwater resources which are essential for unhindered agricultural production continuously experience depletion, in terms of quality and quantity, despite the increasing demand by both agriculture and non-agricultural sectors [8,9]. Recent studies have also predicted an increase in future water scarcity and drought risk by 2031-2060 and 2071-2099, respectively [10,11], thereby signifying a need for immediate short and long term mitigation strategies.…”

Multi-Level Prioritization Analysis of Water Governance Components to Improve Agricultural Water-Saving Policy: A Case Study from Korea

The challenge of unstainable agricultural water usage in Korea has continued interminably despite persisting climate change impacts; thus, necessitating urgent actions to forestall future water crises. However, achieving this goal requires the involvement of stakeholders to develop an effective governance policy concerning water saving. This study investigates the components of water governance following existing water policy gaps. A multi-level Delphi-AHP technique was used to identify and prioritize the essential components of agricultural water governance that can specifically enhance water-saving policy in Korea. The analysis of twenty-nine formulated components (six main and twenty-three sub-components) based on the OECD water policy gaps was conducted. A Delphi-AHP technique with process evaluation of the agricultural water experts’ opinions under pairwise comparisons was used to arrive at the relative order of importance of the components. The order of main components based on the consolidated weight follows core actors (0.316), law, policies, and systems (0.069), budget support (0.135), information sharing and communication (0.099), mutual learning (0.142), and external experts (0.239), while village representatives (0.353), legislation (0.358), central government (0.311), policy committee (0.309), education course (0.374), and facilitator (0.402) were considered as priorities, respectively, for the sub-components of water governance. The findings indicate that strengthening the informal institution could address the water governance gaps in the agricultural sector to achieve water-saving policies. This study recommends a bottom-up approach to water governance that could promote the active participation of core actors such as farmers and villagers in the design of policy and management of agricultural water resources.
