Improving the livelihoods and well-being of the rural poor is an important aim of agricultural development. But improved agricultural productivity does not necessarily translate into improved health and nutrition, either for producers or consumers. How can standard agricultural development strategies—promoting agricultural intensification, greater linkages to markets, and high-value production—...
Many authors have blamed African land tenure systems for the poor agricultural production and environmental degradation in Africa, and therefore the resulting hunger, environmental refugees and the lack of socio-economic progress. The aim of this paper was to investigate the role of tenure security in north-east Ghana and the implications for agricultural production and environmental sustainabi...
Interest in and deployment of wireless monitoring systems is increasing in many diverse environments, including row-crop agricultural fields. While many studies have been undertaken to evaluate various aspects of wireless monitoring and networking, such as electronic hardware components, data-collection procedures, power management, and communication protocols, little information related to phy...
OF THESIS TESTING THE EFFICIENCY OF A SERIES HYBRID DRIVETRAIN FOR AGRICULTURAL APPLICATIONS Because of high fuel costs and rising concern over controlling motor vehicle emissions, there has been a surge in the number of hybrid passenger vehicles on roads in recent years. This transition has not yet been seen with agricultural vehicles. With this in mind, this study created a test scheme to cha...
Molecular breeding of crops is an efficient way to upgrade plant functions useful to mankind. A key step is forward genetics or positional cloning to identify the genes that confer useful functions. In order to accelerate the whole research process, we have developed an integrated database system powered by an intelligent data-retrieval engine termed PosMed-plus (Positional Medline for plant up...
Since 2000, the southwestern Brazilian Amazon has undergone a rapid transformation from natural vegetation and pastures to row-crop agricultural with the potential to affect regional biogeochemistry. The goals of this research are to assess wavelet algorithms applied to MODIS time series to determine expansion of row-crops and intensification of the number of crops grown. MODIS provides data fr...
Agricultural growth has long been recognized as an important instrument for poverty reduction. Yet, measurements of this relationship are still scarce and not always reliable. This paper presents additional evidence at both the sectoral and household levels based on recent data. Results show that rural poverty reduction has been associated with growth in yields and in agricultural labor product...
A Bulgarian project at Maritsa East power station demonstrated the proper transformation of air pollutants (SOx and NOx) into nitrogen fertilizer. Although this technology has not been put into practice in Bulgaria, it seems feasible on an industrial scale and so it may help to ease Portugal’s reliance on imports of nitrogen fertilizer and thereby contain the outfl ow of Portuguese funds. The d...
