“…At the same time, the loss of cultivated land because of rapid industrialization and urbanization [42] and the policy of land fallow give limited space for grain production increase that is driven by increasing planting area. The lack of water resource, overuse of fertilizers, and non-point source pollution have become increasingly prominent issues as well [43,44]. Hence, the traditional mode of higher output driven by input increase is difficult to sustain.…”

Abstract:The grain output of China increased continuously for 11 years from 2004 to 2014, effectively ensuring security of the country's food supply. At the same time, rapid advancement of urbanization and industrialization generated marked changes in the food consumption patterns of residents, and supply-demand structural problems, such as the variety, quality and region of grains, became increasingly prominent. Currently, national food security goes beyond the guarantee of total grain demand. Therefore, both the production and consumption systems must be evaluated to produce a scientific measurement of food security. From the perspective of food production-consumption coordination and matching, this article sets up a multidimensional coupling assessment index system and model, and carries out assessment of the food security level and the warning status of China between 1995 and 2012. Results show that the level of quantity coordination remained high and the level of variety coordination fluctuated before 2006 and continued decreasing afterwards. The regional coordination level largely continued to decline during the whole research period. The level of coordination of Chinese food production-consumption was high overall. The warning situation existed only for four years, but it started to decrease continuously since 2007 because of aggravated structural and regional disharmony. The state of coordination at the early stage primarily reflected variation of food production, but that of the later stage greatly reflected the problems caused by food consumption. In the future, food security of China can be ensured overall, but regional and variety coordination problems may worsen further, which may exert a potentially negative influence on agricultural trade, industrial security and market stability, thereby leading to decrease in food security at the regional and household levels. In the future, this problem can be addressed by ensuring the self-sufficiency of core varieties of grains, building interest coordination mechanisms in the production and sale regions, forming a modern food and nutrition development pattern, and making additional efforts to save grains.

“…Different rates of progress across regions have led to global and regional shifts in the distribution of undernourished populations. While a noteworthy reduction of absolute hunger in the world has occurred, roughly one out of eight people continues to be undernourished (Fan and Brzeska 2014). The overwhelming majority of these people (827 million) live in developing countries, where the prevalence of undernourishment has decreased from 23.6% to 14.3% (Fan and Brzeska 2014).…”

“…During 1994–1996, 1.6 billion were at risk of iodine deficiency. Deficiencies in important micronutrients such as vitamin A, iron, and zinc, known as hidden hunger, plague more than two billion people globally, again primarily in the developing world (Fan and Brzeska 2014). Significant numbers of children in developing countries suffer from micronutrient deficiencies, including anemia (52.4%), vitamin A deficiency (34%), and iodine deficiency (29.6%) (FAO et al 2013).…”

Food Security as a Water Grand Challenge

Perhaps the biggest challenge the world faces is providing sufficient, nutritious, and safe food at the right time for its ever‐increasing population. Considering current world population growth trends, it is estimated that the global population will be about 10 billion by the year 2050. Therefore, food production should at least double in the same period if food security is to be satisfied. Water and land resources play a pivotal role in agriculture and directly connect to food security. At the same time, the capacity to produce food is constrained by global climate changes and increased pressure on land resources. These challenges are more severe in Southern Asia, Sub‐Saharan Africa, and East Asia, where conflict and lack of capacity to fund agricultural research and food production are common. Strategies that simultaneously increase food production and reduce threats to food security are therefore needed. The objectives of this paper are to review the grand challenges of global food security and to propose strategies for mitigating food insecurity, with an emphasis on the link between water resources and food production.

“…Although is unclear the impacts of these changes on agricultural sustainability, in the current year the CO 2 concentration reached unprecedented registered levels on earth surface (about 403 ppm) (Olivier et al, 2017). In this way, add to challenges associated to feed more than nine billions people in the next decades (Jacquemin et al, 2013;Fan et al, 2014), an additional question is related to how to supply the food crescent demand for world growth population in face of increasingly uncertainties about climate stability; which could lead to change of rain regime, besides of increases in frequency of heat and cold waves as predicted to be increasingly common in next decades. In this sense, abiotic and biotic stresses are the major constraints for agricultural productivity on the global scale and projected climate changes could increase their negative effects in the future (Brito et al, 2010Diola et al, 2011;Diola et al, 2013;Weber et al, 2014;Brito et al, 2016;Guimarães et al, 2017;Lisei-de-Sa et al, 2017;Moura et al, 2017a;Moura et al, 2017b) and its increasingly frequency of occurrence will probably influence the plant species distributions, productivity, carbon balance and negatively impacting on physiological resilience capacity of plants in a specific environment.…”

The study was conducted using physiological approach to identify rice accessions with superior performance when subjected to infra-optimum temperatures during initial development phase (V 2 -V 4 ). Forty-two rice genotypes composed by background essentially indica, japonica and indica/japonica cross with a broad genetic and ecological diversity were used. Plants were grown under initial optimum temperatures gradient (OTG -22/32 °C night/day) until V2 stage; subsequently were subjected to infra-optimum temperature gradient (ITG -13/17 °C night/day) during three days; after all genotypes returned to OTG conditions for seven days to recovery. Principal components analysis (PCA) highlighted that the three principal components account for 75.16% of total variation at the end of evaluated period. There were similar contributions of effective quantum yield (Y(II) -stress) and electron transport rate variables after recovery period (ETR -recovery) for PC1. Interestedly, genotypes highly responsive under initial OTG which showed fast initial biomass accumulation were also highly sensitive to stress when subjected to ITG, with accentuated decreases in their physiological performance. Sel. TB 1211-3 line, CTB 1419, CTB 1444, CTB 1455 and AB 13720 progenies showed greater performance for physiological analyzed variables, being potentially useful for breeding efforts aiming improve cold tolerance in rice at initial phase.
