Effects of Low-cost Offsets on Energy Investment – New Perspectives on REDD – AgEcon
Golub, Alexander; Fuss, Sabine; Szolgayova, Jana; Obersteiner, Michael.
Tropical deforestation is one of the major sources of carbon emissions, but the Kyoto Protocol presently excludes avoiding these specific emissions to fulfill stabilization targets. Since the 13th Conference of the Parties (COP) to the UNFCCC in 2007, where the need for policy incentives for the reduction of emissions from deforestation and degradation (REDD) was first officially recognized, the focus of this debate has shifted to issues of implementation and methodology. One question is how REDD would be financed, which could be solved by integrating REDD credits into existing carbon markets. However, concern has been voiced regarding the effects that the availability of cheap REDD credits might have on energy investments and the development of clean...

Large-Scale Modelling of Global Food Security and Adaptation under Crop Yield Uncertainty AgEcon
Fuss, Sabine; Havlik, Petr; Szolgayova, Jana; Schmid, Erwin; Obersteiner, Michael.
Concerns about future food security in the face of volatile and potentially lower yields due to climate change have been at the heart of recent discussions on adaptation strategies in the agricultural sector. While there are a variety of studies trying to quantify the impact of climate change on yields, some of that literature also acknowledges the fact that these estimates are subject to substantial uncertainty. The question arises how such uncertainty will affect decision-making if ensuring food security is an explicit objective. Also, it will be important to establish, which options for adaptation are most promising in the face of volatile yields. The analysis is carried out using a stochastic version of the Global Biosphere Management Model (GLOBIOM)...

Production system based global livestock sector modeling: Good news for the future AgEcon
Havlik, Petr; Herrero, Mario; Mosnier, Aline; Obersteiner, Michael; Schmid, Erwin; Fuss, Sabine; Schneider, Uwe A..
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...

Investment in Irrigation Systems under Weather Uncertainty AgEcon
Heumesser, Christine; Fuss, Sabine; Szolgayova, Jana; Strauss, Franziska; Schmid, Erwin.
Irrigated agriculture will play a crucial role to meet future food demand, but a sustainable water resource management in agriculture is crucial as well. Therefore, the European Water Framework Directive promotes several measures, e.g., the adoption of adequate water pricing mechanisms or the promotion of water-saving irrigation techniques. Since production conditions such as weather and climate development are uncertain, farmers might be reluctant to invest in a water-saving but capital intensive irrigation system. We apply a stochastic dynamic programming approach to analyze a farmer’s optimal investment strategy for either a water–saving drip irrigation system or sprinkler irrigation system under weather uncertainty and assess the probability of...

AGRICULTURAL PRICE VOLATILITY UNDER CLIMATE CHANGE: The Impact of Multiple Objectives on Commodity Prices AgEcon
Fuss, Sabine; Havlik, Petr; Szolgayova, Jana; Obersteiner, Michael; Schmid, Erwin.
Agricultural price volatility has moved to the forefront of research efforts and political discussion, where much work is already being undertaken with respect to the impact of fluctuations in input prices (e.g. fertilizer, feed and energy). In this paper we also want to take into account the impact of climate change on prices via increased volatility in crop yields. In addition, we analyze the impact of having multiple objectives competing for the land on which crops are grown. In particular, we want to address the concerns that have been voiced about biofuel targets and calls for prioritization of food security.
