Lost food, wasted resources: global food supply chain losses and their impacts on freshwater, cropland, and fertiliser use
TLDR
If the lowest loss and waste percentages achieved in any region in each step of the FSC could be reached globally, food supply losses could be halved and there would be enough food for approximately one billion extra people.About:

Yield Trends Are Insufficient to Double Global Crop Production by 2050.
TL;DR: Detailed maps are presented to identify where rates must be increased to boost crop production and meet rising demands, which are far below what is needed to meet projected demands in 2050.
Journal ArticleDOI
Fruit and Vegetable Waste: Bioactive Compounds, Their Extraction, and Possible Utilization.
TL;DR: The types and nature of the waste that originates from fruits and vegetables, the bioactive components in the waste, their extraction techniques, and the potential utilization of the obtained bioactive compounds are described.
Journal ArticleDOI
Determinants of consumer food waste behaviour: Two routes to food waste.
TL;DR: Perceived behavioural control and routines related to shopping and reuse of leftovers are the main drivers of food waste, while planning routines contribute indirectly, while moral norms and perceived behavioural control make no significant contribution.
Journal ArticleDOI
Drivers of food waste and their implications for sustainable policy development
TL;DR: In this article, the authors explored the drivers of residential, institutional, and commercial food waste generation in developed countries, particularly in the U.S., and examined the impacts of food system modernization on food waste, including impacts related to food system industrialization, urbanization, globalization, and economic growth.
Journal ArticleDOI
Consumer-related food waste: causes and potential for action
TL;DR: In this paper, the authors present the results of a literature review and expert interviews on factors causing consumer-related food waste in households and supply chains, highlighting that synergistic actions between all parties are most promising.

TL;DR: It is shown that tremendous progress could be made by halting agricultural expansion, closing ‘yield gaps’ on underperforming lands, increasing cropping efficiency, shifting diets and reducing waste, which could double food production while greatly reducing the environmental impacts of agriculture.
Journal ArticleDOI
Global food demand and the sustainable intensification of agriculture
TL;DR: Per capita demand for crops, when measured as caloric or protein content of all crops combined, has been a similarly increasing function of per capita real income since 1960 and forecasts a 100–110% increase in global crop demand from 2005 to 2050.

TL;DR: Optimizing the need for a key human resource while minimizing its negative consequences requires an integrated interdisciplinary approach and the development of strategies to decrease nitrogen-containing waste.

Global Water Resources: Vulnerability from Climate Change and Population Growth
TL;DR: Numerical experiments combining climate model outputs, water budgets, and socioeconomic information along digitized river networks demonstrate that (i) a large proportion of the world's population is currently experiencing water stress and (ii) rising water demands greatly outweigh greenhouse warming in defining the state of global water systems to 2025.
