Gross changes in reconstructions of historic land cover/use for Europe between 1900 and 2010

Switzerland
Europe

Historic land‐cover/use change is important for studies on climate change, soil carbon, and biodiversity assessments. Available reconstructions focus on the net area difference between two time steps (net changes) instead of accounting for all area gains and losses (gross changes). This leads to a serious underestimation of land‐cover/use dynamics with impacts on the biogeochemical and environmental assessments based on these reconstructions.

Historical landscape dynamics of Inner Mongolia: patterns, drivers, and impacts

Journal Articles & Books
декабря, 2015

CONTEXT: Understanding the causes and consequences of land use and land cover change in drylands is crucial for global sustainability. Inner Mongolia consists of arid and semiarid ecosystems of global importance. OBJECTIVES: Our main goal was twofold: to review the patterns and drivers of land use and land cover change in Inner Mongolia, and to discuss ecological impacts and strategies for promoting landscape and regional sustainability. METHODS: We took an interdisciplinary and retrospective approach, based on historical records and remote sensing data.

Urbanization, Grassland, and Diet Influence Coyote (Canis latrans) Parasitism Structure

Land use change can alter the ecological mechanisms that influence infectious disease exposure in animal populations. However, few studies have empirically integrated the environmental, spatial, and dietary patterns of wildlife epidemiology. We investigate how urbanization, habitat type, and dietary behavior are associated with coyote (Canis latrans) parasitism structure along a gradient of rural to urban land cover using multivariate redundancy analyses. Coyote fecal samples were collected in eight urban and six rural sites in Calgary, Alberta, Canada.

‘Goan Impasse’: land rights and resistance to SEZs in Goa, India

Journal Articles & Books
декабря, 2015
India

Conflicts over land-grabs for industry, infrastructure and urbanization are on the rise in emerging economies. A slew of policy measures undergird such land deals in India but have encountered successful resistance from peasants and citizens groups. In Goa, resistance led to the revocation of the state's special economic zone (SEZ) policy and cancellation of all approved SEZs, many developed by prominent realty firms. As battle over three SEZs continues in the Supreme Court of India, there is hope that commons will be returned to local communities.

Hidden Cost of Eating Meat in South Africa: What Every Responsible Consumer Should Know

Southern Africa

Meat production in South Africa is on an increasing trend. In South Africa rising wealth, urbanisation and a growing middle class means South Africans are eating more processed and high-protein foods, especially meat and dairy products. These foods are more land- and water-intensive than fruit, vegetable and grain crops, and further stress existing resources. Traditional agricultural farms cannot keep up with the increasing demand for animal products and these farms are being replaced with concentrated animal feeding operations.

Urbanization promotes non-native woody species and diverse plant assemblages in the New York metropolitan region

United States of America

The rapid urbanization of the world has significant ecological consequences that shape global biodiversity patterns. The plant communities now common in urban centers may represent new habitats with unique dynamics and the potential for highly modified ecological services. This study, joining extensive spatial and floristic data sets, examined current distribution patterns of non-native and native woody plant species in the New York metropolitan region, USA.

Characterization of vegetation community dynamics in areas affected by construction waste along the urban fringe

Journal Articles & Books
декабря, 2015

The effects of urban sprawl, at the expense of green natural areas, and the increasing anthropogenic pressure on these areas, lead to significant changes in land cover composition and structure. One of the threats and hazardous aspects of the urban sprawl is the disposal of construction site waste (CW) at the cities’ fringes and by the roadsides. The analysis of vegetation community structure over space and time in such areas may contribute to the understanding of community dynamics at the urban fringe following modern human intervention.

prediction of interregional land use differences in Beijing: a Markov model

Journal Articles & Books
декабря, 2015

This study combines statistical methods and a Markov model to analyze interregional differences in land use in Beijing since 2003 and to predict land use changes for 2015 and 2019. First, the paper proposes a new concept, land use flow, which counts the change in area from the beginning to the end of the period of interest, to analyze changing land use patterns using statistical records from 2003 to 2011. Second, based on land use data between 2003, 2007 and 2011, this paper applied a Markov model to the prediction of Beijing land use in 2015 and 2019.

This note aims to provide information and analysis as a basis for a better understanding of the challenges and constraints of achieving gender equality in Bolivia, with a special focus on the intersectionality between gender and ethnicity. Combining and analyzing existing evidence and new data, it seeks to document gender-specific disparities in development outcomes, highlight opportunities and constraints to women’s empowerment, and identify areas in which continuing knowledge gaps are particularly important to understand and address gender inequalities.

This report is about Romanis's Green growth benchmarking, which is a country-level diagnostic that helps define a country’s strengths and vulnerabilities in adopting a path to greener growth. The process of defining a country’s green growth path starts with an analysis aimed at mapping the country’s current position on a multi-dimensional green-growth chart, with each dimension defined by an indicator of green growth.

Agriculture in the rural-urban continuum: a CGIAR research perspective

Ghana

Thirsty and hungry cities are posing significant challenges for the urban-rural interface ranging from food security to inter-sectoral water allocation. Not only is the supply of resources to urban centres a growing challenge in low-income countries, but even more is the urban return flow, as investments in waste management and sanitation, ie the ‘ultimate food waste’, are not able to keep pace with population growth. And where polluted water is used in irrigation to feed the cities, food safety is becoming a crucial component of food security.
