The Third and Fourth Dimensions of Landscape: towards Conceptual Models of Topographically Complex Landscapes

Peer-reviewed publication
Novembro, 2010

Relating spatial patterns to ecological processes is one of the central goals of landscape ecology. The patch-corridor-matrix
model and landscape metrics have been the predominant approach to describe the spatial arrangement
of discrete elements (“patches”) for the last two decades. However, the widely used approach of using landscape
metrics for characterizing categorical map patterns is connected with a number of problems. We aim at stimulating
further developments in the field of the analysis of spatio-temporal landscape patterns by providing both a critical

Is There Surplus Labor in Rural India?

Policy Papers & Briefs
Outubro, 2010
Índia

We show empirically using panel data at the plot and farm level and based on a model incorporating supervision costs, risk, credit-market imperfections and scale-economies associated with mechanization that small-scale farming is inefficient in India. Larger farms are more profitable per acre, more mechanized, less constrained in input use after bad shocks, and employ less per-acre labor than small farms.

Land Grabbing in Africa. A Review of the Impacts and the Possible Policy Responses

Reports & Research
Outubro, 2010
África

Includes the rise of land deals in sub-Saharan Africa; land grabbing and risks for small scale farmers; land grabs: another yoke over women’s land rights?; is land grabbing threatening pastoralism?; opportunity for groups at risk: the African Union’s continental standards on the land question.

Why it makes more sense to invest in farmers than in farmland

Reports & Research
Julho, 2010
África

Large-scale land acquisitions can have lasting repercussions for the future of agriculture, including both agribusiness and family farming. Rather than rushing into land deals, governments and investors should properly consider the wider range of options to invest in agriculture. In many parts of the world, family farmers have proved efficient and dynamic. Working with them can generate healthy returns, avoid the risks associated with land acquisitions, and improve farmers’ livelihoods.

What is a ’smallholder?

Includes ’small-holder’ farmers as potential beneficiaries of agrarian reform in South Africa, a class-analytic approach to small-scale farming, accumulation ’from above’ and ’from below’, policy implications.

Biofuels, land access and rural livelihoods in Tanzania

Reports & Research
Dezembro, 2009
Tanzania
África

Includes trends prospects and policies, biofuel production and land access in Tanzania – laws, policies and procedures, impacts of biofuel investments on land access. Findings and implications cover production models and their impacts on local land access; risks of land alienation – long term impacts; limitations of compensation; use of third-party mediators?; large-scale transfers of land for biofuels are most problematic; linking policy with practice; shortcomings of biofuel guidelines; alternative land holding structures and production models.

SMALL Savannah : an information system for the integrated analysis of land use change in the Far North of Cameroon

Reports & Research
Dezembro, 2009
SMALL Savannah is an Environmental Information System designed for the integrated analysis and sustainable land management in the savannas region of the Far North of Cameroon. This system combines an observation and spatial analysis module for the representation of phenomena from various geographic data sources, with a module for the explanation and prediction of land use pattern and changes, and a dynamic modelling and simulation module for the exploration of possible land use change trajectories.

’Land Grabs’ in Africa: Can the Deals Work for Development?

Reports & Research
Setembro, 2009
África

For many millions in the developing world, land is central to livelihoods, food security, even identity – the result of a direct dependence on agriculture and natural resources. It is not surprising that a recent wave of large-scale land acquisitions in Africa, Central and Southeast Asia, Eastern Europe and Latin America has sparked a major debate. The briefing provides an analysis of this complex and shifting situation, focusing on Africa.

Effects of spatial extent on landscape structure and sediment metal concentration relationships in small estuarine systems of the United States' Mid-Atlantic Coast

Journal Articles & Books
Dezembro, 2008
Estados Unidos

Prior studies exploring the quantitative relationship between landscape structure metrics and the ecological condition of receiving waters have used a variety of sampling units (e.g., a watershed, or a buffer around a sampling station) at a variety of spatial scales to generate landscape metrics resulting in little consensus on which scales best describe land-water relationships. Additionally, the majority of these studies have focused on freshwater systems and it is not clear whether results are transferable to estuarine and marine systems.

Land Reform and Rural Territories: Experiences from Brazil and South Africa

Despite programmes for rural land reform and redistribution around the world, inequitable land distribution and rural poverty remain profound in much of the rural South. Suggests a new approach to land reform and rural development. ‘Rural territorial development’ is based on and encourages shared territorial identity (distinctive productive, historical, cultural and environmental features) amongst different stakeholders and social groupings. Builds on the fact that rural people’s livelihood strategies are complex and often mostly non-agricultural in nature.
