| RESUMEN El presente artículo compara la reforma de la PAC aprobada en junio de 2003 con un hipotético escenario de mayor liberalización en el que se permite la substitución de cultivos COP (cereales, oleaginosas y proteaginosas) por cultivos hortícolas y/o patatas. La simulación se lleva a cabo mediante el cálculo de una función de utilidad multiatributo para cada grupo homogéneo de agricultores: tres grupos en cada una de las tres comunidades de regantes. El método de cálculo de las funciones de utilidad no requiere ninguna interacción con el centro decisor. La validación de los modelos confirma la validez de esta metodología para la simulación de las decisiones de cultivo de estos productores. Los resultados sugieren que con el sistema alternativo... |

| We quantify the emergence of biofuel markets and its impact on U.S. and world agriculture for the coming decade using the multi-market multi-commodity international FAPRI model. The model incorporates the tradeoffs between biofuel, feed, and food production and consumption and international feedback effects of the emergence through world commodity prices and trade. We examine land allocation by type of crop, and pasture use for countries growing feedstock for ethanol (corn, sorghum, wheat, sugarcane, and other grains) and major crops competing with feedstock for land resources such as oilseeds. We shock the model with exogenous changes in ethanol demand, first in the United States, then in Brazil, China, EU, and India, and compute shock multipliers for... |

| 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... |

| In Germany agricultural land use is very heterogeneous with respect to management orientation and productivity even at local level. Also the rate of structural change shows a wide variation. While for a limited number of factors (e.g. farm size) a stable relation to structural change could be widely confirmed for different parts of Germany, the results for other indicators are contradictory. This holds especially for indicators describing to the marginality of a site. Many concerns related to structural change and development of land use intensity, e.g. abandonment of high nature value farmland, are only relevant in a very specific local context. Therefore, it is necessary to establish indicators for farm development on a disaggregated level. This paper... |

| 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... |

| Watershed programme is an important intervention in dryland areas to improve livestock productivity through increased feed and fodder supply. The present study has focused on the impact of watershed interventions on crop-livestock linkages with particular emphasis on how the interventions have affected the quantity of stovers/straws as livestock feeding materials in bridging the demand-supply gap. The study has been carried out in three typical Shivalik foothill watersheds (two treated and one untreated) in the Panchkula district of Haryana state. The impact of watershed development programme has been estimated by adopting both with and without approach and before and after approach. The untreated watershed has derived 65 per cent of its total income from... |

| Land use change in developing countries is of great interest to policymakers and researchers from many backgrounds. Concerns about consequences of deforestation for global climate change and biodiversity have received the most publicity, but loss of wetlands, declining land productivity, and watershed management are also problems facing developing countries. In developing countries, analysis is especially constrained by lack of data. This paper reviews modeling approaches for data-constrained environments that involve methods such as neural nets and dynamic programming and research results that link individual household survey data with satellite images using geographic positioning systems. |
