The near elimination of inland salt marshes in Central Europe occurred throughout the 19th and 20th centuries, and the currently remaining marshes exist in a degraded condition. This work examines the impact of groundwater level on the growth of plants from a seed bank obtained from a degraded salt marsh in proximity to still existing one through an ex-situ experiment. An experimental tank was set up with the sample seed bank experiencing differing levels of water level.

Ejidos, Urbanization, and the Production of Inequality in Formerly Agricultural Lands, Guadalajara, Mexico, 1975–2020

United States of America

The ejido is an institution of communal land tenure and governance administered by the Mexican government. This paper assesses the current visual appearance of landscapes and implicit land use in ejidal lands on the periphery of Guadalajara, Mexico, using Google Street View (GSV) images tagged for signs of urban distress. Distressed landscapes are associated with the temporal process of urban expansion—newer settlements tend to be more visibly impoverished.

Indirect Effects of Grazing on Wind-Dispersed Elm Seeds in Sparse Woodlands of Northern China

Peer-reviewed publication
December, 2020
Global

Grazing leads to the reduction of biomass and plays a critical role in land degradation in arid and semiarid lands. However, the indirect effects of grazing on the ecosystem, e.g., the effect on seed dispersal, have not been well understood. In this study, we built an agent-based model (ABM) to simulate how grazing intensity affects the seed dispersal of elm trees, one of the native vegetation species of temperate woodlands in semiarid lands. The simulated results from the ABM and observed data from the real world were compared to assess the accuracy and validity of the ABM.

Spatio-Temporal Evolution of Land Use Transition and Its Eco-Environmental Effects: A Case Study of the Yellow River Basin, China

Peer-reviewed publication
December, 2020
China

Human activities and environmental deterioration have resulted in land use transition (LUT), which seriously affects the ecosystem service value (ESV) of its region. Therefore, relevant policy measures are urgently needed. Nevertheless, research on the relationships between LUTs and ESVs from the overall watershed scale is lacking. Thus, the geo-information Tupu method was applied to analyze the dynamic patterns of LUT based on land use data from 1990, 2000, 2010, and 2018 of the Yellow River Basin (YRB).

Understanding the Relationships between Extensive Livestock Systems, Land-Cover Changes, and CAP Support in Less-Favored Mediterranean Areas

Peer-reviewed publication
December, 2020
Global

Farm abandonment and over-extensification trends in less-favored livestock breeding areas in the Mediterranean have led to socio-environmental issues that are difficult to assess and address, due to the characteristics of these areas (e.g., poor data availability and reliability). In a study case that presents many of the characteristics common to these areas, we combine qualitative and quantitative approaches to assess (i) the relationship between livestock production and land-cover change and (ii) the drivers of farmer decisions, concerning the types of livestock they breed.

Identifying Land Use Change Trajectories in Brazil’s Agricultural Frontier

Peer-reviewed publication
December, 2020
Brazil
United States of America

Many of the world’s agricultural frontiers are located in the tropics. Crop and cattle expansion in these regions has a strong environmental impact. This paper examines land use and land cover transformations in Brazil, where large swaths of natural vegetation are being removed to make way for agricultural production. In Brazil, the land use dynamics are of great interest regarding the country’s sustainable development and climate mitigation actions, leading to the formulation and implantation of public policies and supply chain interventions to reduce deforestation.

A multi-method approach to explore environmental governance: a case study of a large, densely populated dry forest region of the neotropics

Journal Articles & Books
December, 2020

Semiarid regions are often secondary on the national to global (scientific) agenda, especially if abundant vegetation elsewhere draws attention and the local population is considered backwards thinking and poverty-stricken. The Caatinga, our case study, is such a region, home to millions of Brazilians and a vast biodiversity. Unfortunately, a widely uncoordinated land use change and biodiversity decline are happening, while farmers’ livelihoods are at risk. We hypothesize substantial weaknesses in the current governance practices.

The impact of forestry as a land use on water quality outcomes: An integrated analysis

Journal Articles & Books
December, 2020

The adoption of the EU land use, land use change and forestry (LULUCF) regulation ensures that for the first time afforestation in Europe will contribute toward the achievement of European Union (EU) climate change commitments under the Paris Agreement. However, increased afforestation in Europe could have unintended environmental trade-offs that may hamper the achievement of EU Water Framework Directive targets.

Changes in food access by mestizo communities associated with deforestation and agrobiodiversity loss in Ucayali, Peruvian Amazon

Journal Articles & Books
December, 2020

Few longitudinal studies link agricultural biodiversity, land use and food access in rural landscapes. In this paper, we test the hypothesis that, in a context of economic change, cash crop expansion is associated with deforestation, reduced agrobiodiversity and changes in food access. For this purpose, we analysed data collected from the same 53 upland and floodplain mestizo households in Ucayali, Peru, in 2000 and 2015. We found an emerging transition towards less diversified food access coupled with loss of forest cover and reduced agricultural biodiversity.

Feedback between drought and deforestation in the Amazon

Journal Articles & Books
December, 2020

Deforestation and drought are among the greatest environmental pressures on the Amazon rainforest, possibly destabilizing the forest-climate system. Deforestation in the Amazon reduces rainfall regionally, while this deforestation itself has been reported to be facilitated by droughts. Here we quantify the interactions between drought and deforestation spatially across the Amazon during the early 21st century.

Survey of GHG mitigation policies for the agriculture, forestry and other land use sector

Global

In light of the urgency for policy action to address climate change, this report provides the first detailed global catalogue of targets and policies for mitigating greenhouse gas emissions in the Agriculture, Forestry and Other Land Use (AFOLU) sector. It covers 20 countries which collectively account for nearly half of the world’s AFOLU emissions. Most of these countries have recently set targets within their AFOLU sector as part of national climate mitigation strategies and commitments, although these targets are only legally-binding for two countries.
