Abstract:As the global population continues to grow and resources become increasingly strained, the efficiency and sustainability of agricultural production are becoming increasingly important. Soil sensors play a vital role in this process, providing real-time information on soil conditions to help farmers manage and improve their fields more effectively.Advantages of soil sensors:First, improve ...

Extreme weather, believed to result from climate change and increased atmospheric CO2 levels, is a concern for many. And beyond extreme events, global warming is also expected to impact agriculture.1,2 Although it is expected that climate change will significantly affect agriculture and cause decreases in crop yields, the full effects of climate change on agriculture and human food supplies are ...
Low agricultural water fee collection rates are a problem commonly faced by many developing countries and this is a problem faced by China as it enters the new century. There are two main problem-solving strategies used in different areas of China: increasing the water fee collection rate, or exempting people from paying the water fee. In those areas where the first strategy is pursued, local ...
We used simulation to study how three French sheep production systems could adapt to a new context created by a surge in cereal prices associated with changes in common agricultural policy support. The evaluation criteria were economic performance, energy efficiency, emissions of greenhouse gases, and sensitivity to technical and economic fluctuations. ...
The concept of our paper is based on the recognition, that environment safety and food safety is jointly influenced by the farming system and intensity of farming on the basis of given conditions. Therefore, the complete agricultural system and structure needs remodelling in order to create a management that is based on the sensitivity, stress-counteracting ability, production potential of the ...
The macro–engineering project proposal exploits technologies that have the potential to quickly enliven the arid region surrounding Lake Eyre. The plan is focused on biosaline agriculture. The distinctive macro–project components are: Lake Eyre is gradually filled to a higher level by controlling evaporation and by pumping seawater from the nearby ocean using cheap tensioned textile tubes. Most ...
Society now expects agriculture to fulfil new functions to improve quality of life. This requirement has been reinforced by recent crises. The 1999 French Agricultural Framework Law (LOA) formalised agricultural multifunctionality and included payments to farmers for new practices, which satisfy both social and environmental functions, in addition to economic ones. A voluntary territorial farm ...
One of the main aims of the Rural Development Plan under the EU Common Agricultural Policy is the protection of nitrate sensitive areas through agri–environmental schemes. This paper presents a mathematical programming model for farm planning in agricultural areas that are sensitive to nitrates. ...
This evolution has concurred to strengthen the idea that agriculture as a means of ensuring environment protection is not the kind of agriculture that carries out production activities, but one that carries out conservation tasks. In this frame, the interventions to support agriculture's environmental role should no longer be considered a sort of ...
In this paper, the calibration and prediction capacity of a supply response positive mathematical programming model (PMP) for the Alentejo region are evaluated. The model is calibrated with prices and agricultural subsidies of the base year (2000), using the specification rules of the cost function standard, Paris standard, average cost and exogenous elasticities. Then, the model is utilised for ...
Selecting cost-effective measures to regulate agricultural water pollution to conform to the Water Framework Directive presents multiple challenges. A bio-economic modelling approach is presented that has been used to explore the water quality and economic effects of the 2003 Common Agricultural Policy Reform and to assess the ...
In this paper, the impact of full liberalisation of world cotton markets on Sudan and some selected African countries was estimated. Last version of Agricultural Trade Policy Simulation Model was applied. The results indicate that the liberalisation of cotton markets will lead to an increase in the world market price of cotton, which will have positive impact on the production and trade of the ...
Using statistical matching techniques, economists can now create attribute rich datasets by matching across the common variables in two or more datasets. The farm level spatial microsimulation model developed in this paper uses one of many combinational optimisation techniques – simulated annealing – to match the Irish Census of Agriculture to ...
Received for publication June 18, 2008. Conventional wisdom postulates that leaching losses of N from agriculture systems are dominated by NO3–. Although the export of dissolved organic nitrogen (DON) into the groundwater has been recognized for more than 100 yr, it is often ignored when total N budgets are constructed. Leaching of DON into stream and drinking water reservoirs leads to ...
Multifunctionality of Agriculture (MFA) is a concept that supports the recognition of complex interdependencies between different resources, production processes and outputs of agricultural land use. Political decision making within a sustainable development frame requires extensive information about these interrelationships in order to analyse the impact of implemented policies and to assess ...
Turkey has a particular interest in the WTO agricultural negotiations in view of its significant agricultural sector. This paper undertakes a quantitative analysis of trade liberalisation and its impact on Turkish agriculture. We use UNCTAD's Agricultural Trade Policy Simulation Model (ATPSM). A likely scenario suggests that Turkey may face higher import bills as world prices for cereals are ...
This paper addresses the potential consequences of a political and economic integration of EU and Turkish agriculture and evaluates the resulting challenges. Simulation models reveal declining agricultural prices for Turkey in the case of market integration with the EU. This would lead to less production, more consumption and Turkey becoming a ...
This study introduces a framework for managing information flow in innovation systems. An organisation's capacity to receive information, to share it with others and to learn from it is assumed to be the key factor that shapes the flow patterns and, hence, the performance of the innovation system concerned. The framework is applied to characterise the information structure underlying the ...
While Genetically Modified (GM) crops and foods are in production and on the shelves of supermarkets in many countries, they are still under much criticism and scrutiny around the world. Many studies report that consumers' perceptions towards biotechnology are mixed. The main contribution of this paper is to present a Contingent Valuation (CV) modelling approach that allows for the calculation of ...
Essential requirements of council directives and legal provisions in medical feedstuffs are not satisfied in Germany. The 'Schweinemastskandal' (intensive pig breeding scandal) sheds light on the various stakeholders that exploit ambiguous EU regulatory control structures through the use of hazardous feeding stuff and prophylactic prohibited medication. This case helps the understanding of ...
