Mapping of pastoral corridors: practices and politics in eastern Senegal

Journal Articles & Books
Septiembre, 2014
Senegal

The delineation and protection of transhumance corridors are increasingly seen as critical to maintaining livestock mobility in agropastoral areas of West Africa by allowing passage through areas of increasing cropping pressure. Understanding the local politics surrounding the mapping and protection of transhumance corridors is important for policy formulation. This study reports the findings of group meetings in nine local districts (communautés rurales) in eastern Senegal about recently mapped corridors.

Enclosing the commons: reasons for the adoption and adaptation of enclosures in the arid and semi-arid rangelands of Chepareria, Kenya

Journal Articles & Books
Septiembre, 2015
Kenya

The adoption and adaptation of enclosures in the arid and semi-arid rangelands of sub-Saharan Africa is driven and sustained by a combination of factors. However, reviews indicate that these factors cannot be generalized, as they tend to be case specific. A study was therefore conducted to explore the history and reasons for enclosure establishment in Chepareria, a formerly degraded communal rangeland in north-western Kenya.

WHERE LAND MEETS THE SEA

Reports & Research
Noviembre, 2016
Global

This report provides a synoptic analysis of the legal and governance frameworks that relate to the use and management of mangrove forests globally. It highlights the range of challenges typically encountered in the governance and tenure dimensions of mangrove forest management. This assessment forms part of a broader study that includes national-level assessments in Indonesia and Tanzania. It was carried out under the USAID-funded Tenure and Global Climate Change Program.

Trends in global land use investment: implications for legal empowerment

Journal Articles & Books
Diciembre, 2017
Global

From the mid-2000s, a commodity boom underpinned a wave of land use investments in low- and middle-income countries. While agribusiness, mining and petroleum concessions often involve promises of jobs and public revenues, they have also prompted concerns about land dispossession, exclusionary investment models and infringements of the rights of vulnerable groups. 

Evaluation of Landscape Impacts and Land Use Change: a Tuscan Case Study for CAP Reform Scenarios

Peer-reviewed publication
Julio, 2010

The study uses information from different sources and on different scales in an integrated set of models in order to analyze possible land use change scenarios arising in response to CAP reform. Five main steps were followed: (1) analysis of past land use changes, (2) multivariate analysis of future land use changes using a neural network time series forecast model (Multi-Layer Perceptron Method), (3) modelization of land use change demand (Markovian Chains Method), (4) allocation of the demand to define transition localization, (5) definition of policy scenarios.

The ecological and economic consequences of changing land use in the southern Drakensberg grasslands, South Africa

Peer-reviewed publication
Mayo, 2014
Sudáfrica
África austral

The grassland biome of the southern Drakensberg region of South Africa is characterized by a relatively rich floral biodiversity, including a high level of endemics.  Land use in the area was traditionally dominated by livestock ranching based mainly on indigenous grassland that conserved biodiversity to some degree.  Currently however, market demands and risk factors are shifting land use in the area to a matrix of beef, cropping, dairy and particularly, towards plantation forestry.  A spreadsheet model was constructed to understand how expected land use conversion will likely influence th

Agricultural Set-aside Programs and Grassland Birds: Insights from Broad-scale Population Trends

Peer-reviewed publication
Octubre, 2008
Estados Unidos de América

The Conservation Reserve Program (CRP) is a voluntary set-aside program in the United States designed to amelioratesoil erosion, control crop overproduction, enhance water quality, and provide wildlife habitat by replacing crops with other forms of land cover. Because CRP includes primarily grass habitats, it has great potential to benefitdeclining North American grassland bird populations. We looked at the change in national and state population trends of grassland birds and related changes to cover-specific CRP variables (previous research grouped all CRP practices).

The use of ‘ecological risk‘ for assessing effects of human activities: an example including eutrophication and offshore wind farm construction in the North Sea

Peer-reviewed publication
Julio, 2008

This paper takes the move from the uncertainty surrounding ecosystem thresholds and addresses the issue of ecosystem-state assessment by means of ecological integrity indicators and ‘ecological risk‘. The concept of ‘ecological risk‘ gives a measure of the likelihood of ecosystem failure to provide the level of natural ecological goods and services expected/desired by human societies. As a consequence of human pressures (use of resources and discharge into the environment), ecosystem thresholds can be breached thus resulting in major threats to human health, safety and well-being.

Recent Glacier Recession – a New Source of Postglacial Treeline and Climate History in the Swedish Scandes

Peer-reviewed publication
Diciembre, 2011

Climate warming during the past century has imposed recession of glaciers and perennial snow/ice patches along the entire Swedish Scandes. On the newly exposed forefields, subfossil wood remnants are being outwashed from beneath ice and snow bodies. In Scandinavia, this kind of detrital wood is a previously unused source of postglacial vegetation and climate history. The present study reports radiocarbon dates of a set of 78 wood samples, retrieved from three main sites, high above modern treelines and stretching along the Swedish Scandes.
