Many farmers in the developing world have limited access to agricultural technologies and markets. Mobile phone-enabled services that offer price information and market linkages could contribute towards bridging this gap by reducing uncertainty about expected profits, information asymmetries and market inefficiencies. This article uses the example of the price information and marketing service ...

the changing context for agricultural development has highlighted a strong need to understand and adoptinnovation systems thinking. science, technology and innovation policy has equated rural development toagricultural development. the main objective of this paper was to examine the role of innovation capacity inagricultural sector. with the growing diversification of rural livelihood options i...

Intensive data collection and a modeling study have been underway for the past several years addressing two of the channel estuaries draining into the Gulf of Fonseca, Estero El Pedregal and Estero San Bernardo. Data have been compiled on the shrimp farm configurations, exchange rates, and effluent chemistry. Temperature, salinity, and dissolved oxygen profiles have been measured in the estuary...

This paper presents a scalable digital learning system that can store and provide Web access to digital contents from voluntaries, teachers, and institutions that lack resources or expertise to offer classes over the Internet. We use the server-cluster architecture as a way to create scalable and highly available solutions. However, hosting a variety of contents from different owners on such a ...

Vulnerability assessments have often invoked sustainable livelihoods theory to support the quantification of adaptive capacity based on the availability of capital--social, human, physical, natural, and financial. However, the assumption that increased availability of these capitals confers greater adaptive capacity remains largely untested. We quantified the relationship between commonly used ...

Marine fish farming is an important commercial practice in Hong Kong. Marine fish farms located in eutrophic coastal waters often face the threat of severe dissolved oxygen depletion associated with algal blooms and red tides. On the other hand, mariculture activities also contribute to pollution. The sustainable management of mariculture requires proper siting of the fish farms and stocking de...

Rivers can be contaminated with different pollutants such as trout farms. Evaluation of the effect of trout farm on water quality is important to give new permission for trout farm construction. In current work, the effect of constructed trout farms near the Deinachal River on some physicochemical properties namely chemical oxygen demand (COD), biological oxygen demand (BOD5), dissolved oxygen ...

This paper presents a synthesis of the main theoretical and empirical contributions that analyse production choices of farm households living and operating in developing countries. The review is particularly concerned with recent micro-economic contributions that highlight the trade-off farm households typically face, between full-income risk and expected return, while making production decisio...

With the continuing pressure on Australia’s water resources and interand intra-annual rainfall variability, farmers, especially in rainfed agricultural and pastoral zones, have been developing farm dams as a mean of providing additional water sources for irrigation and stock. The density of farm dams has increased over time, and an accurate knowledge of the spatial distribution of farm dams is ...
