| The adoption and possible abandonment of organic farming has yet received little attention in the literature. As time plays an important role in explaining farming decisions, a dynamic econometric framework, namely duration analysis, is used. The probability of entry to and exit of the organic drystock sector is modeled considering a wide range of economic and non‐economic factors. Organic support payments emerge as important driving factor of adoption over time. The empirical results also highlight the importance of environmental and risk attitudes, farming experience as well as influence of other organic farmers on the probability to adopt organic farming; whereas decisions to abandon organic farming appear to be mainly driven by economic and structural... |

| Computers change rapidly, yet the last survey on computer use in agriculture was in 1991. We surveyed Great Plains producers in 1995 and used logit analysis to characterize adopters and non-adopters. About 37% of these producers use computers which is consistent with the general population. We confirmed previous surveys emphasizing the importance of education, age/experience, and other farm characteristics on adoption. However, we also found that education and experience may no longer be a significant influence. Future research and education could focus on when and where computers are most needed, and therefore when adoption is most appropriate. |

| Privately initiated food quality standards are currently important elements in the marketing of food and agricultural products. At the same time, they stand in the centre of a discussion about potential negative effects on small farmers and farmers in developing countries. This study aims at analysing the adoption of two private food standards, BRC Technical Food Standard and GlobalGAP, at an aggregated cross-country level. The results of the econometric analysis reveal some (potential) barriers for developing countries to access this type of organisational innovation. Certificates seem to be issued more probably in larger and wealthier countries, countries with a better institutional quality, better infrastructural conditions and in former UK colonies. |

| Most adoption studies have employed cross-sectional data in a static discrete choice modelling framework to analyze why some farmers adopt at a certain point in time. The static approach does not consider the dynamic environment in which the adoption decision is made and thus does not incorporate the speed of adoption and the effect of time-dependent elements in explaining adoption. The adoption speed of an innovation is important in various aspects. Based on data from a survey of a random sample of 331 smallholder households in western Kenya, this study investigated determinants of time to adoption of mineral fertilizer, animal manure and compost using Duration analysis. Results revealed that factors that influenced timing of the adoption varied by the... |

| This case study explores the development, dissemination, adoption, and impact of improved tree fallows in rural western Kenya. The processes of technology development and dissemination throughout the region are described and analyzed. To analyze adoption and impact, the paper applies a variety of different data collection methods as well as samples from both pilot areas where researchers maintained a significant presence and non-pilot areas where farmers learned of the technologies through other channels. Sample sizes for the quantitative analysis ranged from almost 2,000 households for measuring the adoption process to just over 100 households for measuring impact indicators. Qualitative methods included long-term case studies for 40 households and focus... |

| 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. |

| The adoption of sustainable agriculture and other sustainable forestry methods that can help to reduce tropical deforestation have received a great deal of attention in the literature (Adesina and Zinnah 1993, Akinola and Young 1985, Feder and Slade 1984, Holden 1993, Kebede et al. 1990). Although results from different studies can be compared in an absolute sense, there are very few individual studies that compare results and determine, through empirical analysis, whether policy can be universally applied. This paper uses farm-level data to determine whether some universal conclusions can be drawn about the adoption of agroforestry by peasant farmers in developing countries by comparing the land use choices of farmers in Rondônia, Brazil and Campeche,... |

| Although technology adoption has been the subject of a great deal of economic research, that focused on the economics of adoption of low-input "sustainable" systems has been much more limited and recent. This paper attempts to explain the recent decline in the use of cover crops using in maize farming in the Department of Atlantida, Honduras. In the early 1970's, farmers in the region began rotating maize with the velvetbean (mucuna ssp.), a system learned from Guatemalan immigrants. Tohe mucuna-maize system decreased the labor required for maize farming even as it increased yields, prevented erosion, and conferred a variety of other agronomic benefits. By 1992, estimates show that the system had diffused among more than 60% of farmers in the Department.... |

| This paper is aimed at relating income fluctuation with adoptable innovations, adopter category and their access to some variables than those explained in the neoclassical economics principle of labor market demand and supply equilibrium. Using a quantitative and qualitative case study of some farmers in two States, we considered whether respondents are earning enough income and what constraints they face. The von Hipple’s lead user concept and decision model of risk aversion under uncertainty were used to explain causes of variability. Notably, farmers with enough steady income have access to market, various information and are less risk averse. |
