| 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.... |

| For U.S. agriculture to continue along a sustainable path of economic development, further production increases must be generated by technologies that are both profitable and more environmentally benign. In this context, we assess the role of these green or sustainable technologies in steering agriculture along a more sustainable path. However, the lack of markets for the environmental attributes associated with green technologies can limit their development. In addition, simply making a technology available does not mean it will be adopted. Experience with green technologies such as conservation tillage, integrated pest management, enhanced nutrient management, and precision agriculture demonstrates that even when technologies are profitable, barriers to... |

| This paper investigates the impacts of population growth, market access, agricultural credit and technical assistance programs, land policies, livelihood strategies and other factors on changes in land management, natural resource conditions and human welfare indicators since 1991 in the northern Ethiopian highlands, based on a survey of 198 villages. We find that population growth has contributed significantly to land degradation, poverty and food insecurity in this region. In contrast, better market access and some credit and technical assistance programs were associated with improvement (or less decline) in land quality, wealth and food security; suggesting the possibility of "win-win-win" development outcomes with appropriate interventions. Land... |

| This article introduces the Integrated Agricultural Production System – IAPS - focusing mainly on the role of information systems necessary for its implementation, as well as the impact it will have for the sustainable development and health quality of the food, produced and offered. Some aspects as traceability and identification, sustainable agriculture, information integration, Codex Alimentarius, among others are all considered. Bibliographical and documental researches were conducted in academic data banks and also participation in international congresses and seminars related to the theme. The conclusions indicate the importance of IAPS’s development in Brazil, as well as the difficulties of developing and implementing this system. It was also... |

| Recent years have seen a growth of interest in the adoption and diffusion of low-input sustainable agricultural technologies among smallholder agriculturalists in developing countries. This paper examines the adoption of one such technology, labranza minima, a form of minimum tillage, among resource-poor agricultural households in villages in central Honduras. Logistic regression is used to analyze the determinants of adoption of minimum tillage among a sample of 250 agricultural households. The results show that plots with irrigation, plots farmed by their owners and plots with steeper slopes were more likely canididates for minimum tillage adoption. Farmer household characteristics are not generally found to represent significant influences on... |

| Soil fertility and the lack of fertilizer use in Africa are frequently discussed topics. The problems of land degradation and low agricultural productivity, which result in food insecurity and poverty, are particularly severe in the rural highlands of Ethiopia. In many areas, a downward spiral of land degradation and poverty appears to be occurring. Finding solutions to these problems requires identifying effective entry points for farmers, governments, and civil society organizations, and understanding the potential impacts and tradeoffs that are likely to arise from alternative interventions. This report seeks to improve that understanding, using a bioeconomic model of land management and agricultural production developed for a community that is fairly... |

| On-farm research (OFR) has increased in popularity in the U.S. in recent years due to heightened interest in sustainability issues, the likely decline in resources available for agricultural research, and increasing pressures for accountability and responsiveness to state and local needs. Information relating to OFR was obtained from 431 commercial Kansas farmers. Data were analyzed to determine the degree of OFR being implemented, and three models were estimated to identify which farmer/farm characteristics influenced its implementation. The results indicate that OFR is commonly implemented, and that several farm/farmer characteristics are related to the degree of OFR initiated. It is proposed that to maximize the return from externally initiated OFR,... |
