Global Hunger: A Challenge to Agricultural, Food, and Nutritional Sciences

Abstract

Hunger has been a concern for generations and has continued to plague hundreds of millions of people around the world. Although many efforts have been devoted to reduce hunger, challenges such as growing competitions for natural resources, emerging climate changes and natural disasters, poverty, illiteracy, and diseases are posing threats to food security and intensifying the hunger crisis. Concerted efforts of scientists to improve agricultural and food productivity, technology, nutrition, and education are imperative to facilitate appropriate strategies for defeating hunger and malnutrition. This paper provides some aspects of world hunger issues and summarizes the efforts and measures aimed to alleviate food problems from the food and nutritional sciences perspectives. The prospects and constraints of some implemented strategies for alleviating hunger and achieving sustainable food security are also discussed. This comprehensive information source could provide insights into the development of a complementary framework for dealing with the global hunger issue.

Modelling the Food Availability and Environmental Impacts of a Shift Towards Consumption of Healthy Dietary Patterns in Australia

“…Concerns regarding threats to future food security are well documented [1,2]. Globally the population is expected to reach nine billion by 2050, and already, the food system is failing to meet the nutrition needs of hundreds of millions of people [2,3]. Furthermore, there is a growing concern that dietary consumption patterns in high-income countries, and emerging trends in dietary patterns in heavily reliant on imports of seafood, and by 2040 may also be reliant on imports of some major agricultural commodities such as nuts and dairy due to increased domestic demand and factors impacting food production such as climate change, land degradation and finite limits on resources.…”

Need for a balance between short food supply chains and integrated food processing sectors: COVID-19 takeaways from India

“…Another interesting fact is that there was an equal distribution of agricultural commodities and food products among global population in the year 1990, but, due to introduction of high-tech agricultural technologies, developed countries started producing surplus food and thus increasing their export potentials due to globalization efforts, whereas developing and underdeveloped countries couldn’t able to produce the desired agricultural inputs due to diminishing agriculture and increasing industrialization. This has led to the widening of unequal distribution of food supply (Wu et al 2014 ). Expansion of industrial agriculture in India does not guarantee a better life for marginalized farmers, especially rural population.…”

Listening to Collaborate: Professional Development for Postsecondary Agricultural Education and Training Instructors Teaching Technical Subjects in Nigeria

“…However, in recent years a resurgence in the drive to use AET has been fueled by a recognition of its potential impact on economic and human capital development (Akryod & Smith, 2007). Globally effective AET instructors are needed for the implementation of authentic learning opportunities which assist pupils in mastering the foundations they will need as productive adults (Wu, Ho, Nah, & Chau, 2014).…”
