ENVIRONMENTAL AND GENETIC EFFECTS ON PRODUCTION TRAITS OF EWES ORIGINALLY FROM DISTINCT ENVIRONMENTS

Pannell, David J..

There has been increased public demand for environment protection, including in rural areas. Government programs and policies have responded to these demands in various ways, such as by attempting to increase farmer awareness of environmental issues, increasing budgets for rural environmental programs, increasing environmental regulation, purchasing water from irrigators for environmental purposes, and encouraging farmer adoption of new environmentally friendly practices. These changes create a number of challenges for farmers, including challenges related to maintaining farm productivity, meeting community expectations, living with less water and evaluating new opportunities. These challenges are described and discussed. While there certainly are...

Wool production and reproductive performance components of similar genotypes, brought from distinct production areas, were evaluated during five years trial at similar environments, such as, joining season and stocking rate on winter improved pasture. The least squares means revealed that the origin (breed) effect concentrated upon the Corriedale ewes wool production, whereas in Romney females it affected the reproductive performance. In the abscence of interaction between origin (breed) and year for most variables, it was assumed that the farm management procedures and/or selection criteria applied on hoggets were determinant of the subsequent lifetime production within each genotype examined. Expecting a better reproductive performance in Romneys, mainly...

The objective of this study was to determine the critical points of the operation of broiler catching for transport to the processing plant from animal and operational perspectives. During catching, chickens, environmental variables (temperature and relative humidity) were constantly monitored to determine the Enthalpy Comfort Index (IEC). Also, the physiological variable rectal temperature (RT) was monitored as an indicator of stress suffered by the birds during this handling procedure. Bird welfare were evaluated by analyzing their behavior. The bag method was effective to prevent the struggling of birds while being taken from the broiler house to the transport truck, reducing physical injuries and losses during catching.

We assess different policies for reducing carbon dioxide (CO2) emissions and promoting the innovation and diffusion of CO2-reducing power technologies: (1) emissions price, (2) tax on fossil power, (3) tradable emissions performance standard, (4) market share requirement for renewables, (5) renewables production subsidy, and (6) R&D subsidy for renewables. We evaluate the relative performance of the policies according to incentives they provide along different avenues for emissions reduction, their efficiency, and other salient outcomes. We also assess how the nature of technological progress-whether it occurs by learning by doing or R&D investment and the degree of knowledge spillovers -affects the desirability of different policies. In a...

Pernet, Fabrice; Barret, Jean; Marty, Claire; Moal, Jeanne; Le Gall, Patrik; Boudry, Pierre.

Mortality of oysters Crassostrea gigas occurred along the coasts of France during summer 2008, causing a serious crisis in French oyster production. During spring to summer 2008, 5 groups of 1-yr old oysters of different origins and ploidy levels deployed in the Thau lagoon (France) were sampled for biometrical and biochemical analyses; environmental parameters were monitored in the same area. Mortality occurred in 2 episodes: 13 May to 10 June and 24 June to 9 July. Wild-collected oysters showed mortality sooner than other groups but total overall mortality was 85% in all groups. Mortality occurred when seawater temperature was >19 degrees C during the reproductive season when energetic reserves of oysters were at their lowest. Energy reserve levels...

Production of one day-old chick production is one of the most important segments in the poultry production business. Broiler chicken incubation environment needs to be homogeneous and adequate so hatchability and final product quality are not affected. This research aimed at evaluating environmental conditions inside a multi-stage setter in a commercial hatchery house. The incubator was split into six areas and data loggers placed in the geometric center to register temperature and relative humidity data; carbon dioxide concentration and number of colony forming units (CFU) of fungi were also sampled and analyzed; Kruskal-Wallis non-parametric test was used for statistical analysis; significant differences in temperature and relative humidity distribution...

Environmental Issues of Agriculture: Social Perception Analysis in Southern Spain

Paper presented at the 24th West Indies Agricultural Economics Conference, Granada, July 19-12, 2002. Environmental issues have become important in trade agreement negotiations. NAFTA explicitly includes environmental provisions and they are affecting ongoing WTO and FTAA negotiations. The final role of the environment in the FTAA is uncertain, given opposition by most of the members. The draft FTAA agreement does not contain a separate section on the environment, but a U.S. position paper indicates that environmental provisions are important and that U.S. negotiators will seek to incorporate environmental concerns into specific chapters such those on investment and agriculture. The large number and varied economic and environmental conditions of the...

Agriculture largely shapes the European ecosystems. Today the environmental social interest and the awareness that some farming practices destroy the natural environment is undeniable. Thus, the European decision maker’s emphasis on integrating social demands within the Common Agricultural Policy becomes unquestionable. In this context, this paper analyses: i) the degree of social compliance with soilerosion control from agriculture in Andalusia (southern Spain); ii) the degree of society’s concern about its agriculture; and iii)the respondent’s features that influence both perceptions.

Environmental Perceptions and Behavioral Change of Hillside Farmers: The Case of Haiti

Bayard, Budry; Jolly, Curtis M..

Land degradation is one of the most serious problems facing resource-poor tropical hillside farmers. Studies examining determinants of farmers’ decisions to invest in land improvement technologies have focused on economic and financial factors, neglecting individuals’ perceptions and awareness of the problems and how they affect land use and behavioral change that enhance environmental sustainability. This study examines Haitian peasants’ environmental behavior structure using a structural equation modeling approach. Specifically, the study examines the effects of perceived susceptibility, seriousness, benefits, and barriers to change on attitude, and the causal effect of attitude on behavior. The influence of the level of resources extracted from the land...

Environmental Policy, Education and Growth: A Reappraisal when Lifetime Is Finite

Environmental Policy, Education and Growth with Finite Lifetime: the Role of Abatement Technology

Pautrel, Xavier.

This article demonstrates that when finite lifetime is introduced in a Lucas (1988) growth model, the environmental policy may enhance growth both in the short- and the long-run, while pollution does not influence educational activities, labor supply is not elastic and human capital does not enter the utility function. This is because finite lifetime and the appearance of newborns at each date creates a turnover of generations which disconnects the aggregate consumption growth to the interest rate. We show that the shorter is the horizon, the greater the effect of the environmental policy on growth, because the higher the “generational turnover effect”. We also demonstrate that when time is not the single production factor in education, the environmental...

Environmental Provisions in Free Trade Agreements

Pautrel, Xavier.

This note shows that the assumptions about the abatement technology modify the impact of the environmental taxation (both the size and the “direction”) on the long-run growth driven by human capital accumulation à la Lucas (1988), when the source of pollution is private consumption and lifetime is finite. When the human capital’s share in the abatement services production is higher (respectively lower) than in the final output production, a higher environmental tax reduces (resp. increases) the allocation of human capital in production sectors (abatement service and final output) and boostes (resp. decreases) the BGP rate of growth. When abatement services are produced with the final output, the environmental taxation does not influence growth.

Environmental Regulations and Agricultural Competitiveness

Despite a failure to achieve closure on the Doha Round of WTO negotiations, regional and bilateral trade agreements involving a variety of countries have continued to be negotiated, signed and implemented. Most of the recent trade agreements have contained some environmental provisions, ranging from a pledge to protect the environment to very extensive environmental requirements. These results appear to reflect a recognition that trade has environmental consequences and that trade agreements can be constructed to help mitigate such effects.

Environmentally sustainable tourism: International and Hungarian relations

The cost of meeting environmental regulations can be a critical factor in determining the competitiveness of a product, since the cost advantages of producers in one country are often very slim. The existence of negative externalities means that prices are lower than would prevail if all costs where included in the prices of the products. Additional costs associated with new regulations have an effect on the continued importance of a country's agricultural exports. Governments often assist their agricultural sectors in overcoming the disadvantages through subsidies, tax breaks, technical assistance or other means. This assistance increasingly takes the form of green payments, which are currently exempt from the WTO limits imposed on domestic subsidies....

David, Lorant; Baros, Zoltan.

Compliance with the principles of sustainability is now a general requirement with respect to any tourism strategy, tourism policy or management. Much has been written about the issue of sustainability and its relationship to tourism management and development. Still, their actual relationship is not always clear, and whilst a number of methodologies profess to be sustainable, there is no clear statement as to how that can be achieved. It is generally accepted, irrespective of the sustainability model used, that there are three key components or strands to sustainability: economic, social and environmental. It is in working towards a balance between the competing demands of all three components that progress towards sustainability can be achieved. One...

Mass mortality outbreaks (90-100%) in both juvenile and adult blue mussels were reported in 2014 along the Pertuis Charentais area of the French Atlantic coast. A series of studies were carried out to learn more about the phenomenon through detecting pathogens, describing environmental conditions and establishing the physiological status of the animals. Bacteria identif ied as belonging to the V. splendidus species were detected in dying mussels and seem able to cause mortality in blue mussels in the laboratory. Unusual environmental conditions (large amounts of fresh water, re-suspension of sediments during a series of storms, and a high renewal rate of specific water masses in Brittany’s Pertuis area) may be partially responsible for sparking the phenomen
