Forecasting the response of Earth’s surface to future climatic and land use changes: A review of methods and research needs
-
In the future, Earth will be warmer, precipitation events will be more extreme, global mean
sea level will rise, and many arid and semiarid regions will be drier. Human modifications of landscapes
will also occur at an accelerated rate as developed areas increase in size and population density. We now
have gridded global forecasts, being continually improved, of the climatic and land use changes (C&LUC)
that are likely to occur in the coming decades. However, besides a few exceptions, consensus forecasts do
not exist for how these C&LUC will likely impact Earth-surface processes and hazards. In some cases, we
have the tools to forecast the geomorphic responses to likely future C&LUC. Fully exploiting these models
and utilizing these tools will require close collaboration among Earth-surface scientists and Earth-system
modelers. This paper assesses the state-of-the-art tools and data that are being used or could be used to
forecast changes in the state of Earth’s surface as a result of likely future C&LUC. We also propose strategies
for filling key knowledge gaps, emphasizing where additional basic research and/or collaboration
across disciplines are necessary. The main body of the paper addresses cross-cutting issues, including the
importance of nonlinear/threshold-dominated interactions among topography, vegetation, and sediment
transport, as well as the importance of alternate stable states and extreme, rare events for understanding
and forecasting Earth-surface response to C&LUC. Five supplements delve into different scales or process
zones (global-scale assessments and fluvial, aeolian, glacial/periglacial, and coastal process zones) in
detail.

Reconciling nature conservation and traditional farming practices: a spatially explicit framework to assess the extent of High Nature Value farmlands in the European countryside
-
Over past centuries, European landscapes have been shaped by human management. Traditional, low intensity agricultural practices, adapted to local climatic, geographic, and environmental conditions, led to a rich, diverse cultural and natural heritage, reflected in a wide range of rural landscapes, most of which were preserved until the advent of industrialized agriculture (Bignal & McCracken 2000; Paracchini et al. 2010; Oppermann et al. 2012). Agricultural landscapes currently account for half of Europe’s territory (Overmars et al. 2013), with ca. 50% of all species relying on agricultural habitats at least to some extent (Kristensen 2003; Moreira et al. 2005; Halada et al. 2011). Due to their acknowledged role in the maintenance of high levels of biodiversity, low-intensity farming systems have been highlighted as critical to nature conservation and protection of the rural environment (Beaufoy et al. 1994; Paracchini et al. 2010; Halada et al.2011; Egan & Mortensen 2012).

Scenarios of future land use change around United States’ protected areas
-
Land use change around protected areas can diminish their conservation value, making it important to
predict future land use changes nearby. Our goal was to evaluate future land use changes around protected
areas of different types in the United States under different socioeconomic scenarios. We analyzed
econometric-based projections of future land use change to capture changes around 1260 protected
areas, including National Forests, Parks, Refuges, and Wilderness Areas, from 2001 to 2051, under different
land use policies and crop prices. Our results showed that urban expansion around protected areas
will continue to be a major threat, and expand by 67% under business-as-usual conditions.
Concomitantly, a substantial number of protected areas will lose natural vegetation in their surroundings.
National land-use policies or changes in crop prices are not likely to affect the overall pattern of land use,
but can have effects in certain regions. Discouraging urbanization through zoning, for example, can
reduce future urban pressures around National Forests and Refuges in the East, while the implementation
of an afforestation policy can increase the amount of natural vegetation around some Refuges throughout
the U.S. On the other hand, increases in crop prices can increase crop/pasture cover around some protected
areas, and limit the potential recovery of natural vegetation. Overall, our results highlight that future
land-use change around protected areas is likely to be substantial but variable among regions and
protected area types. Safeguarding the conservation value of protected areas may require serious consideration of threats and opportunities arising from future land use.
