| Successful mechanical weed control is a crucial aspect in organic soybean production. Six weed control techniques (spring tine harrow, inter row hoe with duckfoot sweeps, separately used or in combinations, inter row hoe with additional tools: finger weeder, torsion weeder, ridging wings) were evaluated concerning the effects on weed ground cover and on plant losses. Soy bean plant stands have been established in various rows spacing using different types of seeders (12.5 cm with seed drill for harrowing variant and 50 cm with single seed drill for hoeing variants). The field trials were conducted at two sites in three years (2011-2013). The weed ground cover in the harrowing variant was higher than in the hoeing variants in three of five environments. In... |

| This paper provides an overview of the most recent developments on Russian cereal markets. A review of annual statistics on domestic production, trade, consumption, and storage of cereals reveals that the improvement in Russia’s net trade position cannot only be explained by increased productivity of grain producers. Exhausted storage capacities and lowered real trade costs after the devaluation of the Russian rouble in 1998 seem to have contributed to these developments. A computable general equilibrium model for Russia based on 1999 data was used for analyzing various economic developments and policy changes. The model simulations show that market protection in the short run, when the flexibility of labor and capital is restricted, may benefit Russian... |

| The liberalization of foreign trade has positively impacted the production of cereals in Mali. The increase in the production of cereals is due to both price increases and the effectiveness of the marketing system. The liberalization made Mali a cereal exporter in contrast with its former status ten years ago, that of a cereals importer Mali supplies its neighboring countries such as Mauritania, Niger, Burkina Faso, Senegal and Cote d’Ivoire with coarse grains. However, subsidies, rapid urbanization, and changes in the food habits of the urban population threaten Mali’s capacity to remain an exporter. To remain an exporter, Mali should, in the long term, process coarse grains into products conforming to the expectations and food habits of the urban... |

| In most developing countries, historically, the main strategy for improving the food sector has focused on increasing farm-level production. But in recent years, with the emphasis on value chain analysis, there has been much more focus on subsector studies, demand-driven approaches, and improving vertical coordination to assure product quality to final consumption markets. Millet, sorghum, and later rice were the traditional leading three cereal crops produced and consumed in Mali. Maize has trailed them for more than two decades, but from mid 1990s on, it has been produced and consumed in much larger quantities. Given the potentials of maize, developing and better organizing its subsector has the potential to not only increase revenues for maize farmers,... |

| Aiming the EU accession put new and significant challenges to the candiadte countries' policies, and the problem of the inclusion of their agricultural sectors was among the most difficult ones. AGMEMOD is an econometric model of the EU-25 + 2 candidate countries (Romania and Bulgaria) agricultural sector. This poster presents the baseline and the scenario results for several key agricultural products of Romania's model developed as part of AGMEMOD model. The model is an econometric, dynamic, multi-product partial equilibrium comodity model. The target of this approach is to evaluate the impact of the Common Agricultural Policy reforms upon the country's agricultural sector in perspective of its accession to the EU. The selected commodities are: soft... |

| When using household-level data in examining consumer's demand it is common to find that consumers purchase only a subset of the available goods, setting the demand for the remaining goods to zero. Ignoring such censoring of the dependent variables in the estimation can lead to biased parameter estimates. In this paper we investigate the household's demand for six types of whole grain and non-whole grain breakfast cereals and products using a censored Almost Ideal Demand System (AIDS) and estimate the parameters of the demand system via Bayesian methods. Using 2006 ACNielsen Homescan data we find that demand for whole grain and non-whole grain ready-to-eat cereals is less responsive to changes in prices; demand for whole-grain bars and non-whole grain hot... |

| Within the context of liberalisation experienced by the Malian economy since the beginning of the 1990s, spatial integration of cereal markets has been considered as a major tool as to avoid localised shortages due to production shortfalls. However, market dynamic reveals since then new patterns: the diversification of urban consumer demand towards "modern cereals", in particular rice and maize, drives the segmentation of the cereal market. As consumer s are likely to substitute traditional cereals, like millet and sorghum, for other cereal types, new market segments emerge. We account for this evolution with a theoretical model à la Hotelling : the good is considered according to two characteristics, the spatial localisation (local market) and the cereal... |

| Irrigation occupies a central position in China’s crop production. However, due to low per capita water resources, much worse, unevenly distributed over regions and time and the rapid increase of water diversions to non-irrigation sectors, irrigation water shortages have become a very serious problem. Without the adoption of effective measures this problem may even threaten China’s food security. Currently, irrigation efficiency is very low in general, irrigation water prices cannot fully recover water supply costs, and irrigation facilities are aging due to the lack of funding for O&M (operation & maintenance). Since water prices are regulated by the government, and not determined by the market, water prices did not work effectively in water... |

| This work was aimed at analysing the effects of the sudden food price explosion followed by price crash which occurred recently on the foreign trade of the food economy. Comparison of the balances of the different countries was difficult due to the differences in the absolute dimensions; therefore a new method was introduced. Firstly, with the help of the “food economic foreign trade profile” extent to which the different product categories (divided by main product groups or by degree of processing) contribute to the foreign trade balance of the given country’s food economy was examined. In the second step, with the help of “profile indexing”, the extent to which the country in question was able to turn to profit the market opportunities offered by the... |

| Through rapid assessment of existing literature and review of policy and other official documents, the report synthesizes the existing knowledge and gaps on policies and institutions and identifies key research issues that need in-depth study. The report provides an overview of the range of key livelihoods and production systems in the Blue Nile Basin (BNB) and highlights their relative dependence on, and vulnerability to, water resources and water-related ecosystem services. It also makes an inventory of current water and land related policies and institutions in the BNB, their organizational arrangements, dynamics and linkages and key policy premises. It highlights the major problems in institutional arrangements and policy gaps and makes suggestions for... |
