Grain cereals such as wheat, barley, rice, and maize are the nutritional basis of humans and animals worldwide. Thus, these crop plants are essential in terms of global food security. We conducted a bibliometric assessment of scientific documents and patents related to wheat and barley through the Scopus database. The number of documents published per year, their affiliation and corresponding scientific areas, the publishing journals, document types and languages were metricized. The main keywords included in research publications concerning these crops were also analysed globally and clustered in thematic groups. In the case of keywords related to agronomy or genetics and molecular biology, we considered documents dated up to 1999, and from 2000 to 2018, separately. Comparison of the results obtained for wheat and barley revealed some remarkable different trends, for which the underlying reasons are further discussed.

Reader Comments The white paper reports the deliberations of a workshop focused on biotic challenges to plant health held in Washington, D.C. in September 2016. Ensuring health of food plants is critical to maintaining the quality and productivity of crops and for sustenance of the rapidly growing human population. There is a close linkage between food security and societal stability; however, global food security is threatened by the vulnerability of our agricultural systems to numerous pests, pathogens, weeds, and environmental stresses. These threats are aggravated by climate change, the globalization of agriculture, and an over-reliance on nonsustainable inputs. New analytical and computational technologies are providing unprecedented resolution at a variety of molecular, cellular, organismal, and population scales for crop plants as well as pathogens, pests, beneficial microbes, and weeds. It is now possible to both characterize useful or deleterious variation as well as precisely manipulate it. Data-driven, informed decisions based on knowledge of the variation of biotic challenges and of natural and synthetic variation in crop plants will enable deployment of durable interventions throughout the world. These should be integral, dynamic components of agricultural strategies for sustainable agriculture.

One-third of the world's food is lost and wasted each year, making reducing food loss and waste one of the promising ways to ensure global food security. This study conducts a comparative analysis of the differences among the factors affecting rice harvest loss of specialized and part-time farmers. Data collected from 1 106 farmers in China were analysed using Tobit regression. The results indicated the following: i) The average rice harvest loss rate of part-time farmers is higher than that of specialized farmers. ii) Among the variables considered, most factors not only increase the loss of part-time and non-rice specialized farmers but also reduce the loss of rice specialized farmers. iii) The use of combine harvesters and the purchase of outsourcing services increases the loss of part-time and non-rice specialized farmers but can reduce the loss of rice specialized farmers. iv) In addition to weather and pests, planting area, terrain conditions, operating attitude, and labour shortage also affect the loss. These findings are valuable to understand how the loss occurs and the differences between specialized and part-time farmers, which will help develop targeted interventions to reduce the loss.

Monitoring global agriculture systems relies on accurate and timely cropland information acquired worldwide. Recently, the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program has produced Global Food Security-support Analysis Data (GFSAD) cropland extent maps at three different spatial resolutions, i.e., GFSAD1km, GFSAD250m, and GFSAD30m. An accuracy assessment and comparison of these three GFSAD cropland extent maps was performed to establish their quality and reliability for monitoring croplands both at global and regional scales. Large area (i.e., global) assessment of GFSAD cropland extent maps was performed by dividing the entire world into regions using a stratification approach and collecting a reference dataset using a simple random sampling design. All three global cropland extent maps were assessed using a total reference dataset of 28,733 samples. The assessment results showed an overall accuracy of 72.3%, 80–98%, and 91.7% for GFSAD1km, 250 m (only for four continents), and 30 m maps, respectively. Additionally, a regional comparison of the three GFSAD cropland extent maps was analyzed for nine randomly selected study sites of different agriculture field sizes (i.e., small, medium, and large). The similarity among the three GFSAD cropland extent maps in these nine study sites was represented using a similarity matrix approach and two landscape metrics (i.e., Proportion of Landscape (PLAND) and Per Patch Unit (PPU)), which categorized the crop proportion and the crop pattern. A comparison of the results showed the similarities and differences in the cropland areas and their spatial extent when mapped at the three spatial resolutions and considering the different agriculture field sizes. Finally, specific recommendations were suggested for when to apply each of the three different GFSAD cropland extent maps for agriculture monitoring based on these agriculture field sizes.

The authors assess the prospects for solving the global food problem based on an analysis of the dynamics of food security indicators at the global and regional levels. The global food problem at work refers to the growing population of a planet affected by hunger and other forms of malnutrition. The food security situation has worsened for five years - in 2015–2019, and the COVID-19 pandemic has further exacerbated the food supply problem. The prevalence of moderate to severe food insecurity has affected more than 25% of the world's population. In lowincome countries, malnutrition affects more than 58% of the population. Food security is threatened by the consequences of the spread of coronavirus infection in the short term. In the medium and long term, climate change and the crisis in the governance of the world economy are the greatest threats. Modern international economic institutions are unable to withstand the prospect of declining global food security.
