Outlines economic threshold models developed by various authors as an aid to decision-making about pest management. Particular attention is given to the models proposed by Stern et al. (1959) and by Headley (1972) and the major differences in their concepts of the economic threshold. Limitations and scope for applying these models is discussed as well as differences in the extent of their applications are reviewed. After considering general issues in this respect, particular matters are given attention such as difficulties raised by complexities in the nature of yield loss function due to uncertainty in pest densities, the presence of multiple-pests, and the occurrence of pesticide resistance. An extension is provided for multiple species pest models to... |

Em 2004, o Acre possuía um Produto Interno Bruto (PIB) igual a R$ 3.241.847.000,00, com PIB per capita igual a R$ 5.143,00. Segundo dados do IBGE, os valores adicionados ao PIB na agropecuária, na indústria e no serviço, foram respectivamente de R$ 179.312.000,00; R$ 853.043.000,00 e R$ 1.999.670.000,00. Nesse contexto, torna-se relevante saber como as atividades econômicas impactam sobre a formação do PIB per capita nos municípios acreanos. Diante disso, a análise do impacto causado pela presença de unidades empresariais, pela pecuária e pela produção agrícola sobre o PIB per capita dos municípios possibilita uma visão da própria economia do estado. A teoria da externalidade é utilizada para referenciar esta pesquisa. Analiticamente, é utilizada a análise... |

This paper uses a cross-sectional approach to analyze the impacts of climate change on animal husbandry and the way farmers adapt. The study is based on surveys of almost 5000 livestock farmers across ten countries in Africa. A traditional Ricardian regression finds that the livestock net revenues of large farms in Africa are more sensitive to temperature than those of small farms. Cross-sectional analysis also reveals that large farms (but not small farms) have fewer animals per farm in warmer places. Farmers tend to select beef cattle and chickens in cool climates and goats and sheep in hot climates. Using the Ricardian results and examining climate scenarios for 2060 and beyond, the net revenues of small farms are predicted to increase as much as 120%... |

The study was initiated with the objectives of elucidating and analyzing potentials, weaknesses, opportunities, constraints and policy options in the development of feed crop farming with an emphasis on secondary crops in Southeast Asian developing countries. In Malaysia, feed crops currently not much to employment, income generation, import substitution and export promotion because the sub-sector is small. The scope of the study is limited to the dominant non-ruminant sector of the livestock industry. This sector, particularly poultry and swine, has not only experienced rapid growth but also produces more than is required for domestic consumption and thus exports to neighbouring countries. |

The major objective of this paper is to identify determinants of market prices for cattle, sheep and goat in the export market value chain starting from pastoral markets to export abattoirs and live animal exporters. The study is based on the information generated through a formal survey conducted in the major pastoral livestock markets of Ethiopia with 128 collectors, small and big traders, feedlot operators, live animal and meat exporters. Hedonic price formation model was used to analyze the survey data. This study identified certain occasions such as Christian fasting, Muslim fasting, holidays and other times; time of a situation whether that specific month falls during ban time or not and season described as wet or dry season as important determinants... |

The study focused on the status and prospects of three major Philippines feed crops (corn, palay & soybean), as they functionally relate to the livestock sector. A detailed discussion on local livestock, poultry, aquaculture, and feed milling industry sub-sectors, as well as the three feed crops is presented to examine the current status of these industries. The study analyzed the trends and projections of supply and demand of feed crops from 1998-2015 and evaluated the strengths, weaknesses, opportunities and threats in developing the feed crop sector in the Philippines. |
