What Drives Crop Land Use Change during Multi-Year Droughts in California’s Central Valley? Prices or Concern for Water?

چکیده
The recent multi-year droughts in California have highlighted the heightened risk of longer and more intense droughts, thus increasing interest understanding potential impacts for major economic activities, such as agriculture. This study examines changes cropping pattern California’s Central Valley between 2007 2016 response to two consecutive (2007–2009 2012–2016), factors driving these changes, impact on groundwater level. Results indicate that experienced a shift from alfalfa, cereals (rice, winter wheat, corn, oats), cotton, nut (almonds, walnuts, pistachios) fruit (grapes, oranges, tomatoes) tree crops. was likely driven by high crop prices, trend price, water pumping cost, particularly relatively water-stressed southern parts Valley. While total cropland use remained same during 2007–2016 (during both wet dry years), they vary county county. Some counties large reductions use, while other increases indicating need county-specific resource management. results also land management (determining size fallow land), well (choice types), are key

Predictors of Chinook salmon extirpation in Californias Central Valley
Chinook salmon, Oncorhynchus tshawytscha (Walbaum), populations have declined rapidly along the western coast of North America since the year 2000, possibly because of factors such as habitat loss, altered hydrology and barriers to migration. However, few analyses have rigorously examined which of these factors actually explain historical patterns of extirpation. Data were compiled on flow regi...
متن کاملWhat Drives Land-Use Change in the United States? A National Analysis of Landowner Decisions
Land-use changes involve important economic and environmental effects with implications for international trade, global climate change, wildlife, and other policy issues. We use an econometric model to identify factors driving land-use change in the United States between 1982 and 1997. We quantify the effects of net returns to alternative land uses on private landowners’ decisions to allocate l...

متن کاملClimate Change or Land Use Dynamics: Do We Know What Climate Change Indicators Indicate?
Different components of global change can have interacting effects on biodiversity and this may influence our ability to detect the specific consequences of climate change through biodiversity indicators. Here, we analyze whether climate change indicators can be affected by land use dynamics that are not directly determined by climate change. To this aim, we analyzed three community-level indic...
