| We introduce a new model for examining the dynamics of uptake of technological innovations in agricultural systems, using the adoption of zero-till wheat in the rice-wheat system in Haryana state, India, as a case study. A new equation is derived which describes the dynamics of adoption over time and takes into account the effect of aggregation (e.g. on a spatial and/or cultural basis) in the adopting population on the rate of adoption. The model extends previous phenomenological models by removing the assumption of homogeneity in the non-adopting fraction of the population. We show how factors affecting the per capita rate of adoption can be captured using cognitive mapping and simulate the dynamics of the adoption process. |

| This paper describes a model for estimating, in a probabilistic framework, expected future consumer surplus from planned new product innovations. The model has been applied to estimations of taxpayer benefits from NASA's New Millenium Program (NMP), which develops new technologies for space science, and to the digital data storage technologies being supported by the Department of Commerce's Advanced Technology Program (ATP). The model uses cost index methods based on consumers' estimated marginal valuation for quality improvements in the technology. Probabilistic values for performance increases are taken from the innovators' own expectations. The analysis reveals the sensitivity of welfare increases to these values, which are assumed to be biased upward.... |

| Economic expansion revaluates continuously the economic and social role of agriculture. Population explosion in the world generates continuously growing demand on foods and industrial raw materials. Supply of increased demand is supported by R&D, at the same time using results of it polarizes the economies. In the agriculture the technical development (i.e. development of technical, technological and biological basis of production, chemicalization, education of human resources) produces potential for increasing efficiency of production. The first period of technical development serves characteristically the supply of quantitative demand, but after it reached the equilibrium of supply and demand, then qualitative development becomes aim. Development... |

| There are differences in performance between farmers. In the Netherlands this has been a major topic of research for at least 30 years. Research has shown that the managerial capacities of farmers play a major role in differences in economic and environmental performance. Management can be measured and the optimal level is not the maximum level. Farmers differ in their objectives, competences and local external situation and therefore their strategies. These strategies can be identified. In recent years strategic management has become more important and this can be supported with consultancy. Farmers also differ in their adoption and innovation behaviour. These micro economic results, that correlate with large differences in income and high prices of fixed... |

| Land is the fundamental income sources for farmers. However, farmers stay in disadvantaged state in the political, economic and social aspects. Their land is exploited and occupied, which facilitates the rapid development of economy, as well as brings the gap between the poor and the rich and the inharmonious disputes. The necessity for protecting the land right of farmers under the new situation is expounded, covering the necessity of carrying out the relevant agricultural policies; the necessity of improving rural economic status and narrowing the gap between urban and rural areas; the necessity of reducing land disputes and constructing harmonious society. The violation of farmers’ land rights is analyzed from two aspects. The first one is the violation... |

| O presente trabalho teve por objetivo analisar as atividades que envolvem o processo de inovação tecnológica no arranjo produtivo local do agronegócio leite em Rondônia, especificamente na região de Rolim de Moura. Em um primeiro momento, analisou-se a inovação tecnológica com base em dados secundários. Posteriormente, realizou-se uma pesquisa de campo na região do município de Rolim de Moura, que faz parte do território do APL, com o intuito de investigar as atividades presentes nas relações entre as firmas do arranjo, parte importante na geração de capacidade inovativa das empresas. Verificou-se que as indústrias de laticínios da região mantêm com seus produtores rurais acordos formais e informais, em que estes concordam em trabalhar cooperativamente, e... |

| ABSTRACT Artificial intelligence may represent an efficient strategy for simulation and optimization of important processes in agriculture. The main goal of the study is to propose the use of artificial intelligence, namely artificial neural networks and genetic algorithms, respectively, in the simulation of oat grain yield and optimization of seeding density, considering the main succession systems of southern Brazil. The study was conducted in a randomized complete block design with four replicates, following a 4 x 2 factorial scheme, for seeding densities (100, 300, 600 and 900 seeds m-2) and oat cultivars (Brisasul and URS Taura), in succession systems of corn/oats and soybean/oats. A multi-layered artificial neural network and a genetic algorithm were... |

| Literature on innovation adoption mechanism has emphasised the positive effect of Single Farm Payments (SFP) and Rural Development Payments on adoption of new technologies. In this context, the expected process of CAP reforming after 2013 is likely to strengthen the role of innovation in the European Union (EU). The objective of this paper is to identify the determinants of the adoption of future innovation, in particular in connection to past innovation, and to assess the role of agricultural policy in the promotion of innovation adoption. The analysis is applied to two regions (Centre and Midi-Pyrénées) in France. Two separate Count models are developed in order to explain famers’ stated intention concerning different intensities of innovation adoption... |
