This study assesses the global mountain population, population change over the 1975–2015 time-range, and urbanisation for 2015. The work uses the World Conservation Monitoring Centre (WCMC) definition of mountain areas combined with that of mountain range outlines generated by the Global Mountain Biodiversity Assessment (GMBA). We estimated population change from the Global Human Settlement Layer Population spatial grids, a set of population density layers used to measure human presence and urbanisation on planet Earth.

In an era of global warming, long-standing challenges for rural populations, including land inequality, poverty and food insecurity, risk being exacerbated by the effects of climate change. Innovative and effective approaches, such as Climate Smart Agriculture (CSA), are required to alleviate these environmental pressures without hampering efficiency.

Although the way in which vegetation phenology mediates the feedback of vegetation to climate systems is now well understood, the magnitude of these changes is still unknown. A thorough understanding of how the recent shift in phenology may impact on, for example, land surface temperature (LST) is important. To address this knowledge gap, it is important to quantify these impacts and identify patterns from the global to the regional scale.

This paper estimates global logistic regression and logistic geographically weighted regression (GWR) models of urban growth in the adjacent border cities of Laredo, Texas in the United States and Nuevo Laredo, Tamaulipas in Mexico, for two time periods from 1985 to 2014. Historical land use and land cover patterns were monitored through Landsat imagery from the United States Geological Survey to identify instances of urban growth through land type change. Data on socioeconomic variables related to urban growth were collected from various sources and used as independent variables.

Global changes impact the human-environment relationship, and, in particular, they affect the provision of ecosystem services. Mountain ecosystems provide a wide range of such services, but they are highly sensitive and vulnerable to change due to various human pressures and natural processes. We conducted a literature survey that focused on two main issues. The first was the identification of quantitative methods aimed at assessing the impact of land use changes in mountain regions and the related ecosystem services.

Conservationists recognize the value of protected area (PA) systems, with adequate coverage, ecological representation, connection, and management to deliver conservation benefits. Yet, governments primarily focus on coverage, disregarding quantification of the other criteria.

The climate crisis demands urgent action, yet we live in a politically polarized and paralyzed world. As governments and other actors struggle over climate change, our environment is irreversibly changing. A United Nations report on the Global Assessment of Biodiversity and Ecosystem Services revealed that three-quarters of the earth’s land-based environment has been significantly altered by human actions.

A community’s choice to give, or withhold, their free, prior and informed consent (FPIC) to a project or activity planned to take place on their land is a recognized right of Indigenous peoples under international law. It is also a best practice principle that applies to all communities affected by projects or activities on the land, water and forests that they rely on.

Using a unique dataset of 703,287 farm operators from the Taiwanese Census of Agriculture merged to administrative records from the National Farmers' Health Insurance (FHI) program, we examine the effects of the enrollment in the FHI program on farmers’ on- and off-farm labor supply and the amount of land they allocate to Taiwan’s land retirement program. In order to account for non-random self-selection into the FHI we use a matching procedure to estimate the impact of the program on land and labor allocations.

The economic and land use consequences of US biofuel programs and their contributions to GHG emissions have been the focal point of many debates and research studies in recent years. However, most of these studies focused on the land use emissions due to the first generation of biofuels such as corn ethanol, sugarcane ethanol, and biodiesel (e.g. [1, 2] [3, 4]). A quick literature review indicates that only a few attempts have been made to estimate these emissions for the second generation of biofuels which convert cellulosic materials into liquid fuels.
