The Conservation Reserve Program (CRP) is the largest land retirement program ever operated in the US. Since its inception in 1985, many researchers have studied the impacts of this program; however, only a few have analyzed how the CRP affects surrounding non–enrolled parcels. In this research I examine how the CRP may affect the conversion of non–cropped land to agriculture, a phenomenon referred to as “slippage” in the literature, and specifically addressed by Wu (2000) and Roberts and Bucholtz (2005). Building on these earlier studies, I empirically model slippage using data derived from satellite imagery that provides information on land cover changes between 1992 and 2001. The study area consists of 1,053 counties located in the Northern Plains, Corn... |

There is significant policy interest in liquid biofuels with appealing prospects for energy security, farm security, poverty alleviation, and climate change. Large-scale commercial biofuel production could have far reaching implications for regional and global markets – particularly those related to energy and land use. As such, large-scale biofuels growth is likely to have significant impacts on global greenhouse gas (GHG) emissions. This paper utilizes a CGE model with explicit biofuel, land, and energy markets. The model is able to estimate the effects on the broad range of input and output markets potentially affected globally by biofuels policies. One of the most controversial issues within the biofuels debate is potential indirect changes in land use... |

Livestock is recognized as one of the major drivers of current and future global change. This is caused on the production side, by the substantial resource requirements (land and water) per unit of output, and the related greenhouse gas emissions, and on the consumption side, by the growing demand due to population and economic growth. Our paper investigates whether productivity gains which enabled to the crop sector to satisfy the increased demand under decreasing real prices, and with little additional land, in the past decades, can be expected in the livestock sector in the future. To answer this question, we implement the recursively dynamic partial equilibrium bottom-up model of the global agriculture and forest sectors (GLOBIOM), expanded by a newly... |

Several studies in the recent past have offered a contrasting and wide range of perspectives on economic and environmental implications of biofuels. In this study we develop a comprehensive and consistent framework for analyzing the global economic interactions and the direct and indirect impacts of biofuels production on greenhouse gas (GHG) emissions. We utilize a global Computable General Equilibrium (CGE) model which consists of interaction of energy commodities with explicit biofuels and their by-product sectors, land endowment classified by agro-ecological zones, and emission of four major GHGs - carbon dioxide, methane, nitrous oxide, fluorinated gases from agricultural and economic activities, including emissions associated with biofuel feedstock,... |

While there has been a large increase in investment in plantation forestry in New Zealand by smallholders during the past decade, there are still many smallholders who have chosen not to become involved in this land use or who are using only a portion of their potentially planted land for forestry. To understand why this is the case, this paper studies two issues, the differences between those who have and have not established plantation forests, and the factors that explain the proportion of land used in forestry by small landholders who have identified that they have potentially plantable land. Land used for forest plantations is treated as a two-step decision process, where first a landowner must decide whether they would consider planting trees at... |

Regional Councils are primarily responsible for environmental management, as specified in the Resource Management Act (RMA), 1991. The Local Government Act 2002 has an integrative component, requiring consideration of social, economic, environmental and cultural well-being of their communities. These two Acts are interesting, as their combination is shaping new governance structures within New Zealand. Different types of policy instruments are available to Regional Councils while carrying out their functions: regulatory, economic and voluntary. The 1990s are characterized by ‘first generation Plans’ of the RMA, which were highly rule focused. In the 2000s a marked shift occurred, mainstreaming ‘community’ and participative approaches to policy. This... |

The amount of land in urban and other special uses increased more than 50 percent since the 1960s in the South. Rural land converted to urban uses is directly related to increases in population in the South. Urban land-use coefficients were estimated to provide a measure of the amount of land converted to urban uses per person added to the population base. These coefficients indicate that from 1974 to 1987 two-thirds to three fourths of an acre of land was converted to urban uses for each person added to the population base. At this rate, about 12.6 million acres are expected to be converted to urban use in the South during the next two decades. |

As the biofuels are emerging as promising alternative transportation fuels across the world, they also offer huge potential for international trade in biofuels. A number of trade barriers such as import tariffs and domestic support have limited the scope for trade in biofuels. The purpose of this study is to analyze the implications of U.S. biofuel mandates, subsidies and import tariffs on global trade and welfare. We utilize the GTAP-BIO model, which was developed as a customized version of the Global Trade Analysis Project (GTAP) model capable of analyzing domestic and trade policy issues associated with biofuels (Birur, 2010). We supplement this model with updated and detailed sectoral level information on feedstock crops, different types of first and... |
