| 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... |

| Background: Global carbon stocks in forest biomass are decreasing by 1.1 Gt of carbon annually, owing to continued deforestation and forest degradation. Deforestation emissions are partly offset by forest expansion and increases in growing stock primarily in the extra-tropical north. Innovative financial mechanisms would be required to help reducing deforestation. Using a spatially explicit integrated biophysical and socio-economic land use model we estimated the impact of carbon price incentive schemes and payment modalities on deforestation. One payment modality is adding costs for carbon emission, the other is to pay incentives for keeping the forest carbon stock intact. Results: Baseline scenario calculations show that close to 200mil ha or around 5%... |

| Fertile land and fresh water constitute two of the most fundamental resources for food production. These resources are affected by environmental, political, economic, and technical developments. Regional impacts may transmit to the world through increased trade. With a global forest and agricultural sector model, we quantify the impacts of increased demand for food due to population growth and economic development on potential land and water use. In particular, we investigate producer adaptation regarding crop and irrigation choice, agricultural market adjustments, and changes in the values of land and water. |

| Discussions on climate change increasingly emphasize the contribution of agricultural activities to anthropogenic greenhouse gases emissions. In this paper, we investigate from a supply to demand side perspective the stress between food demand and climate change challenges up until 2030. We examine how more stringent climate change mitigation policies could alter agricultural markets and put at risk the nutrition possibilities of populations. We use for this purpose GLOBIOM, an applied partial equilibrium model covering, at the world scale and a fine grid resolution, the main land-based sectors: agriculture, forestry and bioenergy. For this exercise, the model is fully linked to a semi-flexible endogenous demand system with non-linear Engel’s curves. Our... |
