A Theoretical and Empirical Analysis of Conservation Reserve Program Participation under Uncertainty AgEcon
Isik, Murat.
This paper develops theoretical and empirical models to understand how farmers formulate their participation strategies when deciding to enroll in the Conservation Reserve Program (CRP) under uncertainty. A theoretical model is employed to obtain the impacts of various factors on the optimal bidding strategies. A selectivity-based econometric model is then used to estimate the probability of enrollment and determinants of rental payments. The theoretical results indicate that the optimal bid is positively related to the expected farming income and environmental benefit scores, and it is negatively related to the degree of risk aversion and the variability of returns. The econometric model shows that land benefits, land attributes, farmer...

Agri-Environmental Policy at the Crossroads: Guideposts on a Changing Landscape AgEcon
Claassen, Roger; Hansen, LeRoy T.; Peters, Mark; Breneman, Vincent E.; Weinberg, Marca; Cattaneo, Andrea; Feather, Peter; Gadsby, Dwight M.; Hellerstein, Daniel; Hopkins, Jeffrey W.; Johnston, Paul V.; Morehart, Mitchell J.; Smith, Mark.
Agri-environmental policy is at a crossroads. Over the past 20 years, a wide range of policies addressing the environmental implications of agricultural production have been implemented at the Federal level. Those policies have played an important role in reducing soil erosion, protecting and restoring wetlands, and creating wildlife habitat. However, emerging agri-environmental issues, evolution of farm income support policies, and limits imposed by trade agreements may point toward a rethinking of agri-environmental policy. This report identifies the types of policy tools available and the design features that have improved the effectiveness of current programs. It provides an indepth analysis of one policy tool that may be an important component of a...

Avaliação do manejo conservacionista sobre a capacidade adaptativa de sistemas de produção agropecuários no estado do Rio de Janeiro. Repositório Alice
MONTEIRO, J. M. G.; HISSA, H. R.; OLIVEIRA, A. P. de; DONAGEMMA, G. K.; PRADO, R. B.; SCHULER, A. E.; COELHO, M. R.; COSTA, M. M. da.
As estratégias de adaptação e mitigação às mudanças climáticas podem ser complementares e gerar benefícios econômicos e sociais para a população rural mais vulnerável. Há uma série de práticas conservacionistas do solo e da água que contribuem para o aumento da resiliência dos sistemas agropecuários frente aos eventos climáticos extremos e, ao mesmo tempo, para o aumento do estoque de carbono do solo e da produtividade agrícola. Mudanças nas práticas de manejo em sistemas produtivos agrícolas e florestais, tais como cultivo mínimo, rotação de culturas, adubação verde, redução da pressão de pastejo e supressão do desmatamento, podem aumentar a produtividade agrícola e seu retorno econômico, podendo contribuir para a segurança alimentar e para a redução da...

Brazilian Germplasm Bank: conservation of genetic resources of sheep and goats. Infoteca-e
FONSECA, J. F. da; SILVA, K. de M..
Brazil is known for its enormous natural animal resources, typically associated with a large diversion of biomes. Although they do not originate in the country, the sheep and goats that were incorporated by settlers after the discovery became the so-called locally adapted animals. This adaptation obeyed the environmental challenges imposed, being more severe in the semi-arid zone - Caatinga biome. Similar to the African savannah, important and unique genotypes of small ruminants live in the Caatinga. Most of them are under some degree of extinction risk mainly because there is no economic interest and/or indiscriminate reproduction with commercially exploited sheep and goats around the world, such as Dorper and Boer, respectively. These specimens were...

Breeds in danger of extintion and biodiversity R. Bras. Zootec.
Blasco,A..
Some arguments currently used to support breed conservation are examined. The central point is that we cannot conserve all breeds because we do not have financial resources enough to keep everything (mainly in developing countries) and in many cases we do not have special reasons to conserve breeds. A breed is a human product and it should not be confused with specie. A breed can be generated or transformed. We can create synthetic breeds with the best characteristics of several breeds. Selection is not exhausting genetic variability (there are several experiments showing that), and genetic variability within breeds is large. We need reasons to keep breeds in danger in extinction. A breed is a tool, and we can decide to keep it when it is useful because it...

Conservation management evaluation on the adaptive capacity of agricultural productive systems in the state of Rio de Janeiro. Repositório Alice
MONTEIRO, J. M. G.; HISSA, H. R.; OLIVEIRA, A. P. de; DONAGEMMA, G. K.; PRADO, R. B.; SCHULER, A. E.; COELHO, M. R.; COSTA, M. M. da.
Strategies for adapting to and mitigating climate change can be complementary and generate economic and social benefits for the most vulnerable rural population. There are a number of soil and water conservation practices that contribute to increasing the resilience of agricultural systems in the face of extreme weather events and, at the same time, to increasing the carbon stock in the soil and consequently agricultural productivity. Changes in management practices in agricultural and forestry production systems, such as minimum cultivation, crop rotation, green manure, reduction. of grazing pressure and suppression of deforestation, can increase agricultural productivity and its economic returns, which may contribute to food security and to reducing the...

Conservation-Compatible Practices and Programs: Who Participates? AgEcon
Lambert, Dayton M.; Sullivan, Patrick; Claassen, Roger; Foreman, Linda F..
In recent years, the Federal Government has increased its emphasis on conservation programs that reward good stewardship on working farmland. This report examines the business, operator, and household characteristics of farms that have adopted certain conservation-compatible practices, with and without financial assistance from government conservation programs. The analysis finds that characteristics of the farm operator and household, in addition to the characteristics of the farm business, are associated with both the likelihood that a farmer will adopt certain conservation-compatible practices and the degree to which the farmer participates in different types of conservation programs. For example, operators of small farm operations and operators not...

Genetic diversity of Brazil nut tree (Bertholletia excelsa Bonpl.) in southern Brazilian Amazon. Repositório Alice
BALDONI, A. B.; TEODORO, L. P. R.; TEODORO, P. E.; TONINI, H.; TARDIN, F. D.; BOTIN, A. A.; HOOGERHEIDE, E. S. S.; BOTELHO, S. de C. C.; LULU, J.; FARIAS NETO, A. L. de; AZEVEDO, V. C. R..
Understanding genetic diversity is the basis of the evolutionary process of any species, as there are mechanisms that increase or reduce genetic variation. Brazil nut (Bertholletia excelsa Bonpl.) occurs in the Amazon region, and is included in the list of endangered species, justifying the importance of this study for the species. This study hypothesized that genetic diversity among individuals collected at different locations in the Amazon (between groups) is greater than genetic diversity between individuals from the same location (within groups). We aimed to study the genetic diversity of four populations of B. excelsa, located in native forests in the Amazon region of the state of Mato Grosso. DNAs were collected from 50 adult trees at each four...

Nurturing Diversified Farming Systems in Industrialized Countries: How Public Policy Can Contribute Ecology and Society
Iles, Alastair ; ESPM, University of California, Berkeley; iles@berkeley.edu; Marsh, Robin; College of Natural Resources, University of California, Berkeley; robinmarsh@berkeley.edu.
If diversified farming systems (DFS) are to thrive again in the United States, policies and preferences must evolve to reward the environmental and social benefits of sustainable farming and landscape management. Compared with conventional agricultural policies, policies aiding ecological diversification are underdeveloped and fragmented. We consider several examples of obstacles to the adoption and spread of diversified farming practices in the U.S. industrialized agricultural system. These include the broader political economic context of industrialized agriculture, the erosion of farmer knowledge and capacity, and supply chain and marketing conditions that limit the ability of farmers to adopt sustainable practices. To overcome these obstacles and...

Participation in Conservation Programs by Targeted Farmers: Beginning, Limited-Resource, and Socially Disadvantaged Operators' Enrollment Trends AgEcon
Nickerson, Cynthia J.; Hand, Michael S..
Beginning, limited-resource, and socially disadvantaged farmers make up as much as 40 percent of all U.S. farms. Some Federal conservation programs contain provisions that encourage participation by such “targeted” farmers and the 2008 Farm Act furthered these efforts. This report compares the natural resource characteristics, resource issues, and conservation treatment costs on farms operated by targeted farmers with those of other participants in the largest U.S. working-lands and land retirement conservation programs. Some evidence shows that targeted farmers tend to operate more environmentally sensitive land than other farmers, have different conservation priorities, and receive different levels of payments. Data limitations preclude a definitive...

The Consequences of Co-benefits for the Efficient Design of Carbon Sequestration Programs AgEcon
Feng, Hongli; Kling, Catherine L..
In this paper, we study the social efficiency of private carbon markets that include trading in agricultural soil carbon sequestration when there are significant co-benefits (positive environmental externalities) associated with the practices that sequester carbon. Likewise, we investigate the efficiency of government-run conservation programs that are designed to promote a broad array of environmental attributes (both carbon sequestration and its co-benefits) for the supply of carbon. Finally, policy design and efficiency issues associated with the potential interplay between a private carbon market and a government conservation program are studied. Empirical analyses for an area that represents a significant potential source of carbon sequestration and...
