Predicted avian responses to bioenergy development scenarios in an intensive agricultural landscape
Conversion of native prairie to agriculture has increased food and bioenergy production but decreased wildlife habitat. However, enrollment of highly erodible cropland in conservation programs has compensated for some grassland loss. In the future, climate change and production of second-generation perennial biofuel crops could further transform agricultural landscapes and increase or decrease ...
متن کاملSetting priorities for land management to mitigate climate change
BACKGROUND No consensus has been reached how to measure the effectiveness of climate change mitigation in the land-use sector and how to prioritize land use accordingly. We used the long-term cumulative and average sectorial C stocks in biomass, soil and products, C stock changes, the substitution of fossil energy and of energy-intensive products, and net present value (NPV) as evaluation crite...
متن کاملThe power of bioenergy-related standards to protect biodiversity.
The sustainable production of bioenergy is vital to avoiding negative impacts on environmental goods such as climate, soil, water, and especially biodiversity. We propose three key issues that should be addressed in any biodiversity risk-mitigation strategy: conservation of areas of significant biodiversity value; mitigation of negative effects related to indirect land-use change; and promotion...
متن کاملMitigating greenhouse gases: The importance of land base interactions between forests, agriculture, and residential development in the face of changes in bioenergy and carbon prices
a r t i c l e i n f o The forest sector can contribute to atmospheric greenhouse gas reduction, while also providing other environmental, economic, and social benefits. Policy tools for climate change mitigation include carbon-related payment programs as well as laws and programs to impede the loss of agricultural and forest lands to development. Policy makers will base their expectations of th...
متن کاملPerennial grasslands enhance biodiversity and multiple ecosystem services in bioenergy landscapes.
Agriculture is being challenged to provide food, and increasingly fuel, for an expanding global population. Producing bioenergy crops on marginal lands--farmland suboptimal for food crops--could help meet energy goals while minimizing competition with food production. However, the ecological costs and benefits of growing bioenergy feedstocks--primarily annual grain crops--on marginal lands have...
