Elsevier is a world-leading provider of information solutions that enhance the performance of science, health, and technology professionals.

All knowledge begins as uncommon—unrecognized, undervalued, and sometimes unaccepted. But with the right perspective, the uncommon can become the exceptional.

That’s why Elsevier is dedicated to making uncommon knowledge, common—through validation, integration, and connection. Between our carefully-curated information databases, smart social networks, intelligent search tools, and thousands of scholarly books and journals, we have a great responsibility and relentless passion for making information actionable.

Ecosystem service evaluation to support land-use policy

Journal Articles & Books
декабря, 2012

Regular economic activity takes into account ecosystem goods and services that are exchanged for money in the market (e.g. food, fibre, water) but normally ignores more intangible ones left away from market transactions (e.g. soil protection, climate regulation, disturbance control, habitat provision), even in cases when they become irreversibly impaired.

Framework for systematic indicator selection to assess effects of land management on ecosystem services

Journal Articles & Books
декабря, 2012
Netherlands

Land management is an important factor that affects ecosystem services provision. However, interactions between land management, ecological processes and ecosystem service provision are still not fully understood. Indicators can help to better understand these interactions and provide information for policy-makers to prioritise land management interventions. In this paper, we develop a framework for the systematic selection of indicators, to assess the link between land management and ecosystem services provision in a spatially explicit manner.

Mapping ecosystem service supply, demand and budgets

Journal Articles & Books
декабря, 2012

Among the main effects of human activities on the environment are land use and resulting land cover changes. Such changes impact the capacity of ecosystems to provide goods and services to the human society. This supply of multiple goods and services by nature should match the demands of the society, if self-sustaining human–environmental systems and a sustainable utilization of natural capital are to be achieved. To describe respective states and dynamics, appropriate indicators and data for their quantification, including quantitative and qualitative assessments, are needed.

REDD+ and rural livelihoods

Journal Articles & Books
декабря, 2012
Mozambique
China

Focusing on incentive schemes that induce participation in land-use activities to supply environmental services, this paper examines the potential impacts of REDD+ on livelihoods, in particular with respect to incomes and poverty alleviation. Two case studies, each at a different scale, are presented. First, the N’hambita Community Carbon Project in Mozambique, a REDD+ project, promoted agro-forestry and reforestation activities along with alternative livelihoods.

land-use systems approach to represent land-use dynamics at continental and global scales

Journal Articles & Books
декабря, 2012

Most of the current global land cover datasets and global scale land-use models use a classification of land cover based on the dominant land cover type within a distinct region or pixel. Such a classification disregards the diversity and intensity of human influence on land systems. In this paper we propose a novel way of classification and modeling land-use using a classification based on land-use systems (LUSs) that represent specific combinations of human-environment interactions. A cluster analysis was used to identify and map these LUSs.
