An assessment of the implications of alternative scales of communal land tenure formalization in pastoral systems

Peer-reviewed publication
Abril, 2020
Etiópia

Pastoralism faces diverse challenges, that include, among others, land tenure insecurity, that has necessitated the need to formalize land rights. Some governments have started regularizing rights for privately owned land, but this is complex to implement in pastoral areas where resources are used and managed collectively. Our aim was to assess how the scale of communal land tenure recognition in pastoralist systems may affect tradeoffs among objectives such as tenure security, flexibility, mobility, and reduction of conflicts.

Revisiting forest transition explanations: The role of “push” factors and adaptation strategies in forest expansion in northern Phetchabun, Thailand

Peer-reviewed publication
Março, 2019
Tailândia

Researchers and policy makers are increasingly looking at the drivers of forest recovery (or forest transition) for inspiration in their search for win-win solutions to deforestation. However, causal generalizations regarding forest transitions are subject to significant problems. First, forest transition theory (FTT), at least in its simplest renditions, tends to emphasize socially benign processes and fails to pay sufficient attention to the causal role—and social impacts—of negative (push) dynamics.

Questioning the use of ‘degradation’ in climate mitigation: A case study of a forest carbon CDM project in Uganda

Peer-reviewed publication
Dezembro, 2016
Uganda

An urgent need to stop degradation is frequently cited as support for climate mitigation efforts involving forests. However, lessons learnt from social science research on degradation narratives are not taken into consideration. This creates a risk of problematic degradation narratives being used to legitimise forest carbon projects. This study examined a Clean Development Mechanism (CDM) forest plantation in Uganda, where incomplete and partly contradictory evidence on land use change was interpreted in a way that overemphasised degradation.

Drought tolerant species dominate as rainfall and tree cover returns in the West African Sahel

After the severe droughts in the 1970s and 1980s, and subsequent debates about desertification, analyses of satellite images reveal that the West African Sahel has become greener again. In this paper we report a study on changes in tree cover and tree species composition in three village landscapes in northern Burkina Faso, based on a combination of methods: tree density change detection using aerial photos and satellite images, a tree species inventory including size class distribution analysis, and interviews with local farmers about woody vegetation changes.

Property-level direct and indirect deforestation for soybean production in the Amazon region of Mato Grosso, Brazil

Peer-reviewed publication
Outubro, 2018
Brasil
Estados Unidos

Brazil’s Soy Moratorium solidified the world’s largest traders’ commitment to stop soybean purchases from production areas deforested after July 2006. The aim was to remove deforestation from the soybean supply-chain and halt one of the main drivers of forest loss in the Amazon biome. In this study, we investigated changes in deforestation at the property-level for the period 2004 to 2014.

Energy crops, the edible oil processing industry and land use paradigms in Romania–An economic analysis

Peer-reviewed publication
Janeiro, 2018
Romênia

The purpose of this research is to explore the issue of the land used for sunflower and its production as raw material for edible oil processing industry in Romania. The relations between consumption, as main component of demand, and production and import, as sources of supply, on the sunflower oil market are investigated. The case study of the edible oil market is discussed because of the alarming growth in imports after Romania’s accession to the European Union and, furthermore, because of sunflower crop implications on land use in the context of the food vs. fuel competition.

Demand for second-stage land certification in Ethiopia: Evidence from household panel data

Peer-reviewed publication
Outubro, 2014
Etiópia

Ethiopia has implemented one of the largest, fastest and least expensive land registration and certification reforms in Africa. While there is evidence that this ‘first-stage’ land registration has had positive effects in terms of increased investment, land productivity and land rental market activities, the government is now piloting another round of land registration and certification that involves technically advanced land survey methods and computer registration.

Using spatially explicit data to improve our understanding of land supply responses: An application to the cropland effects of global sustainable irrigation in the Americas

Peer-reviewed publication
Maio, 2018
Noruega
Américas

Land supply elasticities determine the rates of land conversion in global policy models. However, they are only available for few countries in the world. Therefore, analysts seeking to improve the spatial resolution of their models are forced to impose regionally homogeneous parameters over highly heterogeneous regions. This article estimates spatially explicit land supply elasticities using gridded data for the American continent. These estimates reasonably reproduce changes in land use observed at different levels of geographical aggregation across the continent.

Environmental scanning and futures wheels as tools to analyze the possible future themes of the commercial real estate market

Peer-reviewed publication
Fevereiro, 2016
Global

The commercial real estate market is closely linked to the surrounding society, as commercial buildings have several economic, environmental, political, social and cultural influences. Correspondingly, the surrounding society, its actors and the different forces of change appearing in the market environment also have their own influence on the real estate market environment and its future development.

Alternative use of wheat land to implement a potential wheat holiday as wheat blast control: In search of feasible crops in Bangladesh

Peer-reviewed publication
Fevereiro, 2019
Bangladesh

The first occurrence of wheat blast in Bangladesh was confirmed in wheat (Triticum aestivum) fields in February 2016 and re-occurred in the subsequent years. This study explores the potential of alternative use of current wheat land as a strategy to combat the disease. Economically feasible alternative crops would need to be cultivated in the current wheat area by implementing a potential ‘wheat holiday’ – that is discontinuing wheat cultivation for a few years – be it in the 10 blast affected districts, in blast vulnerable districts or the entire country.

To leave or not to leave? Understanding determinants of farmers’ choices to remain in or abandon agri-environmental schemes

Peer-reviewed publication
Junho, 2018
Itália
Estados Unidos

Effectiveness of Agri-Environmental Schemes (AESs) as tools to enhance the rural environment can be achieved not only by increasing uptake rates, but also by avoiding participating farmers abandoning the scheme once they are in. For this reason, it is important to also consider what affects farmers’ decisions to remain in the scheme rather than leave it at the end of the contractual obligation. However, up to now, there has been very little on this issue in the literature.

Public-private partnership in enhancing farmers’ adaptation to drought: Insights from the Lujiang Flatland in the Nu River (Upper Salween) valley, China

Agriculture is an important type of land use but suffers from drought, especially under global climate change scenarios. Although government is a major actor in helping farmers to adapt to drought, lack of funds has constrained its efforts. Public-Private Partnership (PPP) mechanism has been widely applied in urban infrastructure development to raise fund for public goods and services, but very few studies explored its role in rural areas.
