New production from public and exclusive varieties released by the small grains breeding program at Virginia Tech generated cumulative discounted benefits of $41 million from 2000 to 2018. Fitted yields from field trials were combined with acreage estimates to generate weighted average yields...

It is widely recognized that climate change makes the weather more erratic. Since the combination of temperature and precipitation is a major driver ofgrain crop productivity, more frequent extreme rainfalls and heat waves, flooding and draught tend to make grain production and hence grain...

The study of evapotranspiration (ET) is of great theoretical and practical significance for understanding the regional ecological and environmental problems and hydrological cycle processes. The Grain for Green Project (GFGP) in the Chinese Loess Plateau was used as the study area. Based on...

An extraordinary high-strength dilute Mg-0.8Al-0.1Ca-0.6Mn (wt. %) alloy wire was successfully developed by hot drawing, which exhibits high tensile yield strength of 394 MPa, ultimate tensile strength of 431 MPa and moderate elongation to failure of 6.0%. The high strength was mainly attributed...

A novel mathematical model based on the recently proposed Changing Grain Size Model (CGSM) was developed to take into account the grain size distribution, the sintering effect, and the grains overlapping phenomenon in the particle during the carbonation and calcination of pure limestone. The...

One of the key materials for all-solid-state batteries based on oxide electrolytes is the polycrystalline Li 7 La 3 Zr 2 O 12 (LLZO). It has been reported that metallic Li can accumulate at LLZO grain boundaries during operation, causing a short circuit and, hence, a failure of the battery....

Grain size is a critical factor determining materials properties but is challenging to be modulated in nanoscale. Here, we found the grain size can be enhanced from ~23 nm to ~557 nm for Cu but slightly from ~30 nm to ~145 nm for Cu 96 W 4 with the substrate temperature from 298 to 773 K using...

Policy, administration and industry need medium-term projections of the expected developments in the agri-food markets for their decision-making processes. The EU Commission presents such projections for the EU as a whole in December of each year. Those projections and their assumptions...

The study identifies the possibilities of the grain complex of Siberia to supply grain for export. The role of the state and the main regulatory documents of the federal and regional levels, aimed at the development of the grain market and its export from Siberia, have been determined. Using...

Zambia and Zimbabwe have experienced food security emergencies of varying severity, mainly caused by drought and floods in some areas. Like several countries in Africa and elsewhere, the two countries have developed and used Strategic Grain Reserves (SGR) to cope with food emergencies and other...

Zambia and Zimbabwe have experienced food security emergencies of varying severity, mainly caused by drought and floods in some areas. Like several countries in Africa and elsewhere, the two countries have developed and used Strategic Grain Reserves (SGR) to cope with food emergencies and other...

States across the country are taking steps towards providing digital identities to beneficiaries of their Public Distribution System. In doing so, use of Aadhaar based biometrics seems to be the preferred choice of method. However, this method has been widely criticized for several reasons such...

How did the telegraph improve market integration in late imperial China? We exploit differences in the exogenous timing of telegraph construction in different prefectures from 1870 to 1911. The empirical results show that the arrival of the telegraph within a prefecture pair reduced the ratio of...

Production of cereal crops is a thriving industry in Lesotho comprising of maize, sorghum and wheat. The percentage change in composition of these cereal crops in terms of production, yield and area is not well documented. The objects of study were therefore to (i) compare the changes in the...

Quality control can happen at the farm level. However, adoption of better agricultural practices largely depends on the availability of appropriate technology, the introduction of improved varieties, and farmers’ awareness and training

The effect of water-heat treatment and time of electromagnetic irradiation on the yield and quality of flattened wholegrain cereal from emmer wheat is investigated. A comparative analysis of cereal yield and cooking time at different moisture contents and time of electromagnetic irradiation of...

This paper provides a general overview of the current status and key challenges of the Ethiopian wheat value chain. Wheat is an important staple food crop in Ethiopia. Improving wheat production and productivity is therefore a key part of the agenda in the Ethiopian government’s food security...

Russia has moved from being a large importer of grain, soybeans, and soybean meal during the late Soviet period to a major grain exporter. The country has become the world's top wheat exporter, supplying 20-23 percent of total world exports in 2017-2018. This article examines how Russia's...

Getreide ist ein wichtiges Grundnahrungsmittel. In dieser Dissertation analysiere ich gemeinsam mit meinen Koautoren, wie Mensch und Natur Getreideproduktion und -handel in Deutschland zu verschiedenen Zeiten beeinflussen. Im ersten Papier entwickeln wir einen Ansatz, um die gegenwärtige...

The paper intends to examine the effects of the accession to the European Union on Romania's cereal sector, in the period 2007-2016, in terms of evolution of areas cultivated with wheat and maize, production in volume and value terms, consumption and self-sufficiency, exports and imports, as...

Consumption smoothing and temporal price arbitrage are the two main economic motives for grain storage in semi-subsistence economies. Nonetheless, little has been documented on the determinants of households' grain storage behavior. Using a rich panel data from maize producing households in...

How much did the telegraph improve market integration in imperial China? We exploit differences in the timing of telegraph construction in different prefectures in the late 19th to the early 20th centuries to show that telegraph presence in both prefectures decreased the monthly grain price...

The European Commission years ago adopted a policy of encouraging the substitution of motor carrier haulage of freight with rail and water carrier haulage, as part of its “green” agenda of reducing fuel consumption, emission of pollutants, carbon intensity, and road congestion. Regarding...

Existing literature has not yet identified the common determinants of price volatility transmission in agricultural commodities from international to local markets and has rarely investigated the role of self-sufficiency measures in the context of national food security. We analyzed several...

International grain prices experienced a sharp increase during the 2020/2021 marketing season, most likely due to the unprecedented increase of imported grains by China. What would be the possible impact on international grain markets if China remains a strong grain importer? The scenario...
