TLDR
In this paper, the authors argue that the displacement, rebound, cascade, and remittance effects that are amplified by economic globalization accelerate land conversion, and that sound policies and innovations can reconcile forest preservation with food production.Abstract:
A central challenge for sustainability is how to preserve forest ecosystems and the services that they provide us while enhancing food production. This challenge for developing countries confronts the force of economic globalization, which seeks cropland that is shrinking in availability and triggers deforestation. Four mechanisms—the displacement, rebound, cascade, and remittance effects—that are amplified by economic globalization accelerate land conversion. A few developing countries have managed a land use transition over the recent decades that simultaneously increased their forest cover and agricultural production. These countries have relied on various mixes of agricultural intensification, land use zoning, forest protection, increased reliance on imported food and wood products, the creation of off-farm jobs, foreign capital investments, and remittances. Sound policies and innovations can therefore reconcile forest preservation with food production. Globalization can be harnessed to increase land use efficiency rather than leading to uncontrolled land use expansion. To do so, land systems should be understood and modeled as open systems with large flows of goods, people, and capital that connect local land use with global-scale factors.read more

Assessing land use change impact on stream discharge and stream water quality in an agricultural watershed
TL;DR: In this article, the authors analyzed the temporal and spatial variability of the land use and land cover change impacts on hydrology and water quality in the Big Sunflower River Watershed and applied these LULC changes in the SWAT model to demonstrate the impacts on stream discharge, total suspended sediments (TSS) concentrations, total nitrogen (TN), and total phosphorus (TP) yields.

Assessing Regional-Scale Impacts of Short Rotation Coppices on Ecosystem Services by Modeling Land-Use Decisions.

TL;DR: Simulating the spatial distribution of short rotation coppices in the landscape of the Mulde watershed in Central Germany by modeling profit-maximizing farmers under different economic and policy-driven scenarios using a spatially explicit economic simulation model indicates that SRCs negligibly affect trade-offs between individual ESS.

Global projections of 21st century land-use changes in regions adjacent to Protected Areas.
TL;DR: Successful management of buffer regions will be imperative to ensure effectiveness of PAs and to facilitate climate-induced shifts in species ranges, as projections from the four land-use scenarios may diverge substantially in magnitude and direction of change.
Journal ArticleDOI
Jevons paradox and the loss of natural habitat in the Argentinean Chaco: the impact of the indigenous communities' land titling and the Forest Law in the province of Salta.
TL;DR: In this article, the authors used multivariate statistical methods to assess the effect of important institutional changes, including the promulgation of the Forest Law in the Province of Salta and the titling of communal lands to Indigenous Peoples (IPs), on the loss of natural forests, shrublands and grasslands in the Chaco Salteno.

TL;DR: A multifaceted and linked global strategy is needed to ensure sustainable and equitable food security, different components of which are explored here.

Use of U.S. Croplands for Biofuels Increases Greenhouse Gases Through Emissions from Land-Use Change

TL;DR: This article found that corn-based ethanol, instead of producing a 20% savings, nearly doubled greenhouse emissions over 30 years and increased greenhouse gases for 167 years, by using a worldwide agricultural model to estimate emissions from land-use change.

Proximate causes and underlying driving forces of tropical deforestation.
Helmut Geist,Eric F. Lambin +1 more
TL;DR: Tropical deforestation is driven by identifiable regional patterns of causal factor synergies, of which the most prominent are economic factors, institutions, national policies, and remote influences driving agricultural expansion, wood extraction, and infrastructure extension (at the proximate level).
Journal ArticleDOI
Global food security under climate change
TL;DR: It is found that of the four main elements of food security, i.e., availability, stability, utilization, and access, only the first is routinely addressed in simulation studies, indicating the potential for further negative impacts beyond those currently assessed with models.

TL;DR: It is shown that the best type of farming for species persistence depends on the demand for agricultural products and on how the population densities of different species on farmland change with agricultural yield, and that high-yield farming may allow more species to persist.
