| Unlike other resources such as petroleum, coal, and copper, forests are renewable. Yet, in many respects forests historically have been treated as a nonrenewable resource in that forest stocks were depleted or "mined" and loggers moved on to exploit other "deposits." The lands were often put to other uses, typically agricultural, or allowed to regenerate naturally. This paper looks at technical change in forest extraction, i.e., logging under a number of different conditions. It finds that, on average, labor productivity has been increasing in recent decades. However, total factor productivity in the US has declined in recent years. In addition, the study examines the tree-growing potential of plantation forestry. It finds that there is underway a... |

| 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... |

| Recognizing that science and technology research (S&T) is one of many inputs into the broader development process, USAID/Mali, via its Initiative to End Hunger in Africa, requested an assessment of the current S&T situation in Mali. USAID asked the assessment team to produce a comprehensive strategic options plan for a Malian S&T agenda that would identify priority short-term actions to stimulate uptake of S&T results likely to make significant contributions to the attainment of Mali’s broad development goals, while simultaneously developing a coherent longer-term action plan to maintain and improve the human, physical, and financial capital needed to generate future streams of S&T results. The scope of work for the assessment team... |

| Recent changes in structure of the U.S. pork industry reflect, in many ways, past changes in the broiler industry. Production contracts and vertical integration in the broiler industry facilitated rapid adoption of new technology, improved quality control, assured market outlets for broilers, and provided a steady flow of broilers for processing. Affordable, high-quality chicken products have contributed to continual increases in U.S. chicken consumption, which has surpassed pork and beef on a per capita basis. Incentives for contracting and vertical integration in the pork industry may yield comparable results. If so, these arrangements might be expected to result in larger supplies of higher quality pork products at economical prices. |

| During the last 3 decades, donors and governments have invested in the development and dissemination of new technologies in the semi-arid tropics of West Africa. Though a wide range of improved technologies has been developed, adoption remains low without a significant impact on crop productivity, rural income and poverty. Agricultural transformation as occurred in East Asia has not yet occurred in the semi-arid tropics of West Africa. This paper uses data from a regional survey of rural households in 3 countries in West Africa (Burkina Faso, Mali, and Niger) to identify the determinants of uptake of improved technologies. Limited productivity gain is found to be a major constraint to the uptake of technologies. In addition, poorly functioning... |

| This report focuses on recent trends in the food supply chain. Chapters on food manufacturing, wholesaling, grocery retailing, and food service provide a detailed overview of structure, performance, information systems, new technology, and foreign direct investments. The report also contains a comprehensive set of appendix tables containing sales, concentration, trade, productivity, and other indicators. At the time of publication, most of the data sets used in this report included data through the year 2000. |
