Driver distraction has become a critical area of study both for research in investigating human multitasking abilities and for practical purposes in developing and constraining new in-vehicle devices. This work utilizes an integratedmodel approach to predict driver distraction from a primarily cognitive secondary task. It integrates existing models for a sentence-span task and driving task and ...

Introduction This chapter addresses the question “Can smallholder livestock production systems in developing countries be transformed to take advantage of the increasing demand for meat?”, a question that has been posed by many authors (for example, Tarawali et al. 2011). On the basis of a case study that followed smallholder cattle development in Ea Kar, a district in the central highlands of ...

We present a unique, biologically consistent, spatially disaggregated global livestock dataset containing information on biomass use, production, feed efficiency, excretion, and greenhouse gas emissions for 28 regions, 8 livestock production systems, 4 animal species (cattle, small ruminants, pigs, and poultry), and 3 livestock products (milk, meat, and eggs). The dataset contains over 50 new g...

Crop-livestock farms across Africa are highly variable due to in agroecological and socioeconomic factors, the latter shaping demand supply of livestock products. 21st century very different from most mixed elsewhere world. African crop-livestock smaller size, have fewer livestock, lower productivity less dependency on imported feed than countries Europe, Americas intensive agricultural systems...

Abstract Agricultural systems must increase productivity while conserving the natural resource base and optimizing ecosystem services to meet converging challenges posed by a growing human population, increasing costs of production inputs, widespread environmental degradation. Thus, sustainability concerns justify needs for readjustment pasture strategies redefining role forages in livestock pr...

The global food system is experiencing profound changes as a result of anthropogenic pressures. The ever-increasing human population (more than 9 billion by 2050), together with changes in consumption patterns (i.e., increasing demand for livestock products) caused by urbanization, increasing incomes, and nutritional and environmental concerns, is shaping what we eat, who eats, and how much, mo...

Livestock production and trade are critical for the food security and welfare of rural households in sub-Saharan Africa. In Cameroon, animal trade consists mainly of live cattle commercialized through livestock markets. Identifying the factors contributing to cattle price formation is critical for designing effective policies for sustainable production and for increasing food availability. In t...

Current practices for handling drainage water in the western San Joaquin Valley (WSJV) are not sustainable. The soil quality of 300,000 ha of land in the WSJV is adversely affected by the presence of shallow or perched water (0 to 1.5 m). Without a means of disposing of drainage water, increasing amounts of farmland in the WSJV will become salt impaired, and will be removed from production. Usi...
