Food losses can occur during production, postharvest, and processing stages in the supply chain. With the onset of worldwide food shortages, interest in reducing postharvest losses in cassava has been increasing. In this research, the main goal was to evaluate biochemical changes and identify the metabolites involved in the deterioration of cassava roots. We found that high levels of ascorbic a...

War as an acceptable component of intergroup relations is usually resorted to when every other option may have failed. This is given its usually devastating consequences on both individuals and groups. To a great extent the thirty-month Nigerian Civil War practically devastated the Igbo food economy and in particular its food production systems. However, given the need to survive, especially un...

Food security challenges faced by FN people are unique, especially for those living in remote and isolated communities. Conceptualizations of food insecurity by FN people are poorly understood. The purpose of this study was to explore the perceptions of food...

BACKGROUND: Many key global sustainability challenges are closely intertwined (examples are provided in the figure). These challenges include air pollution, biodiversity loss, climate change, energy and food security, disease spread, species invasion, and water shortages and pollution. They are interconnected across three dimensions (organizational levels, space, and time) but are often separat...

This paper surveys the literature on pollinator declines and related concerns regarding global food security. Methods for valuing the economic risks associated with pollinator declines are also reviewed. A computable general equilibrium (CGE) approach is introduced to assess the effects of a global catastrophic loss of pollinators. There appears to be evidence supporting a trend towards future ...

This study examines the productivity and resilience of agroecosystems in the Korean Peninsula. Having learned valuable lessons from a Chapman University project funded by the United States Department of Agriculture which concentrated on the semi-arid region of southwestern United States, our joint Korea—Chapman University team has applied similar methodologies to the Korean Peninsula, which is ...

OBJECTIVES Responses to food insecurity in Canada have been dominated by community-based food initiatives, while little attention has been paid to potential policy directions to alleviate this problem. The purpose of this paper is to examine food security circumstances, participation in community food programs, and strategies employed in response to food shortages among a sample of low-income f...

Hunger, malnutrition, food insecurity and famines are still persistent in many regions globally. Especially on a local level new concepts of targeting food insecurity need to be implemented. Prior to applying new practical concepts the initial situation has to be understood accurately. Therefore, this methodology paper aims at enhancing monitoring systems in times of food scarcity. The overall ...
