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

Spillover effect offsets the conservation effort in the Amazon
TL;DR: In this article, the authors used the telecoupling framework to evaluate the spillover effects of two supply chain agreements implemented in the Amazon biome as examples and evaluated their spillover effect to the Cerrado.

Does global meat consumption follow an environmental Kuznets curve
TL;DR: In this article, the authors used data on meat consumption, per capita income, and other socioeconomic variables for 150 countries to determine whether data support the hypothesis that per capita meat consumptions in 150 countries are higher than those in the USA.

Provisioning ecosystem services supply and demand: The role of landscape management to reinforce supply and promote synergies with other ecosystem services
TL;DR: In this paper, a detailed quantitative assessment of ecosystem services over time in Biscay, Basque Country, Spain is presented, where the aim is to identify ways of balancing the local provisioning ecosystem service supply and demand and to enhance sustainable land use.

Analyzing Land Cover Change and Urban Growth Trajectories of the Mega-Urban Region of Dhaka Using Remotely Sensed Data and an Ensemble Classifier
TL;DR: Using the machine learning algorithm Random Forest, combined with multi-date Landsat imagery, this article classified eight periods of land cover maps with up-to-date spatial and temporal information of urban land between the period of 1972 and 2015 for the mega-urban region of greater Dhaka in Bangladesh.

Multiple factors drive regional agricultural abandonment.
TL;DR: Two different drivers of agricultural abandonment were found: inefficient cultivation and decreasing numbers of farmers, and the main factors leading to agricultural abandonment differed among regions, especially in Hokkaido in northern Japan.

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).

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.
