“…The food price hikes of 2007-08 highlighted a need to expand beyond a single-sector focus to multi-sectoral coordination of all the systems that support food security (Grafton et al 2015a). Beddington's (2009) 'perfect storm' analogy, the concept of sustainable planetary boundaries of Rockström et al (2009) and the Bonn Declaration (GWSP 2013) all exemplify the need for a major policy shift towards a transdisciplinary approach.…”

We analyse the threats of global environmental change, as they relate to food security. First, we review three discourses: (i) 'sustainable intensification', or the increase of food supplies without compromising food producing inputs, such as soils and water; (ii) the 'nexus' that seeks to understand links across food, energy, environment and water systems; and (iii) 'resilience thinking' that focuses on how to ensure the critical capacities of food, energy and water systems are maintained in the presence of uncertainties and threats. Second, we build on these discourses to present the causal, risks and options assessment for decision-making process to improve decisionmaking in the presence of risks. The process provides a structured, but flexible, approach that moves from problem diagnosis to better risk-based decision-making and outcomes by responding to causal risks within and across food, energy, environment and water systems.

“…Rapid population growth [1,[3][4][5][6][7], decreasing agricultural productivity [8][9][10], climate change [3,10,11], natural resource scarcity [3,12], and biofuel production [3,[13][14][15][16][17][18] collectively undermine the current and future capacity of global food production systems. The risk of food insecurity is no longer a challenge exclusive to lesser-developed countries.…”

“…While there have been considerable effort to identify strategies to enhance and diversify current food production systems [4,5,9], of equal importance is an increasing realisation of significant inefficiencies in the global food system due to food loss and waste (FLW) [6,[21][22][23][24][25]. Global FLW has been estimated to represent 27% to 50% of total agricultural production [26][27][28][29][30][31].…”

Quantifying Postharvest Loss and the Implication of Market-Based Decisions: A Case Study of Two Commercial Domestic Tomato Supply Chains in Queensland, Australia

2017

Using a multi-disciplinary approach, this study quantifies horticultural postharvest losses of two medium-sized (annual pack volume 4500 t) commercial, domestic, tomato supply chains. Quantification of loss was based on weight or volume, consistent with direct measurement methods of the Food Loss and Waste Accounting and Reporting Standard 2016 and qualitative techniques were used to identify the drivers of the loss and contextualise the findings. Postharvest loss was found to be between 40.3% (55.34 t) and 55.9% (29.61 t) of the total harvestable product. It was determined that between 68.6% and 86.7% of undamaged, edible, harvested tomatoes were rejected as outgrades and consequently discarded due to product specifications. Between 71.2% and 84.1% of produced tomatoes were left in the field and not harvested. This study highlights significant factors contributing to high levels of food loss and waste. Edible products are being removed from the commercial food supply chain, rejected as outgrades deemed cosmetically defective due to market-based decisions. With only 44.1% and 59.7% of the harvestable crop reaching the consumers of the two supply chains, respectively, it is perhaps more appropriate to describe a food "waste" chain as opposed to a food "supply" chain.

“…There are major challenges involved with managing land to produce food, while ensuring the availability and cleanliness of water for humans and the environment . Until recently, much thinking has been based on single sectors focussed on water, food, or the environment.…”

Water quality and UK agriculture: challenges and opportunities

There are high aspirations for environmental water quality targets in the UK, but requirements for significant growth in agricultural production to meet both food security objectives and provide viable livelihoods for farmers make these hard to achieve. Significant water quality challenges are related to nutrients, pesticides, pharmaceuticals, pathogens, sediments and habitat alteration. To facilitate the challenges posed, there is a need for predictive, spatially distributed models to be developed that encompass the key aspects of agriculture and water management in order to inform future policy and organizations with an interest in land management. Additionally, there needs to be recognition from policy makers that different solutions are needed in different agri‐water systems and that it often takes many years or decades for policies to have a sustained water quality impact. Long‐term support for research infrastructure and the scientific skills base is required to enable measurement and data analysis necessary to inform decision making. Farmers need clearly articulated information on the issues and potential solutions on which to make informed management decisions regarding water. There are existing solutions to some problems and this knowledge needs to be effectively disseminated with appropriate incentives for implementation to have maximum impact. Greater collaboration between researchers, industry, and policy makers, with the necessary framework to deliver effective joint working, is urgently needed. There is also a need for a wider societal understanding of the land–water system and the various ways in which society pays (and might pay in the future) for the real value of water.
