Revisiting food security in 2021: an overview of the past year

Abstract

Articles published in Food Security in 2021 are reviewed, showing a wide range of topics covered. Many articles are directly linked with "food" and associated terms such as "nutritive", "nutrition", "dietary", and "health". Another important group is linked with (food) "production" and a range of connected terms including: "irrigation", "cultivated", "organic", "varieties", "crop", "vegetable", and "land". A third group of terms refers to the scales at which food security is considered: "household", "farmer", "farm", "smallholder", "community", "nation" and "region". A few themes of Food Security are considered: (1) food supply and demand, food prices, and global trade; (2) food security in households; (3) food production; (4) value chains and food systems; (5) the evolution of the concept of food security; and (6) global nutrition. In a last section, perspectives for Food Security are discussed along four lines of thoughts: the level of inter-disciplinary research published in Food Security; the importance of the Social Sciences for food security as a collective good underpinned by other collective goods within food systems; the balance between the Global South and the Global North in Food Security; and a warning that urgent global challenges that vitally interact with food security may be left unattended as a result of the current public health emergency.

Food Security: 3D Dynamic Display and Early Warning Platform Construction and Security Strategy

“…In order to ensure the scientificalness of warning situation indicators, we select five suitable warning situation indicators using principal component analysis [ 58 ], namely, total output, grain planting area, irrigation area of cultivated land, the proportion of grain exports to primary agricultural products exports, and grain reserve rate, to replace the original ten indicators, which are more straightforward and more representative. After selecting the independent variable, we need to select a comprehensive dependent variable that can reflect food security [ 59 , 60 ].…”

A Scientometric Review of Grain Storage Technology in the Past 15 Years (2007–2022) Based on Knowledge Graph and Visualization

“…However, global food security is facing serious challenges. In recent years, adverse factors affecting world food security have increased [ 3 ]. The interplay of economic recession and food trade supply chain disruption is caused by international conflicts and extreme weather [ 4 ].…”

Quantitative Evaluation and Obstacle Factor Diagnosis of Agricultural Drought Disaster Risk Using Connection Number and Information Entropy

“…Food security is a hot topic that arouses constant attention from the international community [ 1 , 2 ]. With the increasing global climate change and the impact of human activities, the frequency, intensity, and scope of influence of drought increase significantly; thus, the drought disaster risk continues to increase.…”
