The development of biofuels is not only related to energy and environment, but also closely the global wealth gap food security. In recent years, with rapid economy increasing population, demand for increasing. At same time, due negative impact use fossil fuels on more people are beginning consider using as substitutes. As a kind biofuel, grain fuel has attracted attention. Food ...

We study numerically and analytically the coarsening of stripe phases in two spatial dimensions, and show that transient configurations do not achieve long ranged orientational order but rather evolve into glassy configurations with very slow dynamics. In the absence of thermal fluctuations, defects such as grain boundaries become pinned in an effective periodic potential that is induced by the...

As a major part of farming sustainability, the issues of grain production and its quality improvement have been important in many countries. This paper aims to address these issues in China. Based on the data from the main production provinces and by applying the stochastic frontier analysis methodology, we find that the improvement of transportation and the use of agricultural machinery have b...

Arsenic (As) is naturally present in all soils and can accumulate to toxic levels rice (Oryza sativa L.) grains under some production conditions. It also reduce grain yields, posing a double threat global food security. Plant genetics affect the amount of As accumulated grains. A growing body evidence suggests that one mechanism plants use detoxify limit concentrations (grain-As) sequester vege...

This paper uses the global trade analysis project (GTAP) to evaluate impact of grain export restrictions on world food security during COVID-19 epidemic. The study found that distort market prices, which in turn consumption and production, harm interests consumers farmers some countries, threaten security. In this regard, maintaining convenience is wise choice all countries. It necessary tighte...

Non-grain production (NGP) on cultivated land has become a common phenomenon due to the prosperity of rural economy and optimisation agricultural structure. However, excessive use cultivating for NGP threatened food sustainable land. To halt this trend ensure security, authors paper applied novel non-grain index measure NGP, which could reflect multiple activities; designated Hubei Province as ...

Food security plays an important role in maintaining national stability and sustainable development of human society, its research has become a hot issue at present. Shandong is the main grain producing area China, production food security. Accordingly, this paper based on county climate change, yield, sown area, fertilizer use, total power rural machinery, population data Province from 1995 to...
