A linkage between the biophysical and the economic: Assessing the global market impacts of soil erosion

Peer-reviewed publication
Juin, 2019
Global

Employing a linkage between a biophysical and an economic model, this study estimates the economic impact of soil erosion by water on the world economy. The global biophysical model estimates soil erosion rates, which are converted into land productivity losses and subsequently inserted into a global market simulation model. The headline result is that soil erosion by water is estimated to incur a global annual cost of eight billion US dollars to global GDP.

Evaluating municipal landscape plans and their influence on selected aspects of landscape development – An empirical study from Germany

Peer-reviewed publication
Novembre, 2020
Allemagne

In this paper we examine the question of whether and how municipal landscape plans exert a positive influence on and/or correlate with selected aspects of the landscape. To this end, a representative sample of municipal landscape plans in Germany and a statistical-quantitative evaluation approach are used to uncover correlations between planning and landscape development. As a result, we can show that municipalities which draw up a landscape plan have a higher proportion of natural areas and a lower hemeroby index, i.e. a lower level of human influence.

Owner or tenant: Who adopts better soil conservation practices?

Peer-reviewed publication
Août, 2015
République tchèque
Norvège

Land tenure security is widely considered to be a fundamental factor in motivating farmers to adopt sustainable land management practices. This study aims to establish whether it is true that owner-operators adopt more effective soil conservation measures than tenant-operators, and whether well-designed agro-environmental instruments can provide sufficiently strong motivation to compensate for the differences between these two groups.

Trade-offs between high class land and development: Recent and future pressures on Auckland's valuable soil resources

Peer-reviewed publication
Juin, 2014
Nouvelle-Zélande

Sustainable land management is essential to meeting the global challenge of securing soil and water resources that can support an ever increasing population. In Auckland, New Zealand's largest city, population growth is forecast to increase from 1.5 to 2.5 million by 2040 which will put immense pressure on the region's soil resources.

Knowledge flows: Farmers’ social relations and knowledge sharing practices in ‘Catchment Sensitive Farming’

Peer-reviewed publication
Décembre, 2019
États-Unis d'Amérique

The move towards sustainable agriculture requires a more detailed understanding of farmers’ knowledge(s) and knowledge practices. Increasingly, it is important to understand not only what farmers understand, but how their knowledge practices incorporate others – especially given the emerging call for environmentally-orientated policy measures to move beyond an individual farmer focus. This paper considers how farmers engage with, utilise and share knowledge through a focus on the Catchment Sensitive Farming (CSF) initiative in the UK.

Criteria for selection and evaluation of biosphere reserves in support of the UNESCO MAB programme in South Africa

The biosphere reserve model is a global designation in accordance with UNESCO’s Man and the Biosphere Programme. Biosphere reserves are required to fulfil three functions as prescribed by UNESCO, namely conservation, sustainable development and logistic support. Worldwide, the 669 biosphere reserves in 120 countries are experiencing different degrees of effectiveness in fulfilling these functions.

Understanding information about agricultural land. An evaluation of the extent of data modification in the Land Parcel Identification System for the needs of area-based payments – a case study

Peer-reviewed publication
Avril, 2020
Pologne
États-Unis d'Amérique

The development the GIS technology and growing access to spatial data encourage greater use of information for various purposes. Users may not be aware that data pertaining to the same fragment of land (in aspect of geometry or description attributes), but acquired from different sources do not always adequately reflect reality. After Poland's accession to the European Union, the EU Member States have undertaken to develop a Land Parcel Identification System (LPIS) as part of the Integrated Administration and Control System in every country.

Registration of private interests in land in a community lands policy setting: An exploratory study in Meru district, Tanzania

Peer-reviewed publication
Novembre, 2020
Tanzania

Current Tanzanian land law offers registration of private interests in land in the form of Certificates of Customary Rights of Occupancy (CCROs) within a broader community lands approach. We conducted qualitative research on the issuance of CCROs along a mountain slope transect in Meru district in northeast Tanzania. This area features intensified smallholder agriculture that evolutionary theory suggests is well adapted for registration of private interests in land.

Lawless land in no man’s land: The undesignated public forests in the Brazilian Amazon

Peer-reviewed publication
Novembre, 2020
Brésil

The Brazilian Amazon has 49.8 million hectares (Mha) of public forestlands not allocated by the federal or state governments to a specific tenure status: the so called undesignated public forests (UPF). Historically, these public forests have been vulnerable to land grabbers and land speculation. Here, we highlighted the imminent threat in UPF by quantifying their accumulated deforestation, all of which is illegal, for the period 1997–2018 and the potential illegal occupation.

Understanding environmental, health and economic activity interactions following transition of ownership in gold mining areas in Tanzania: A case of private to public

Peer-reviewed publication
Novembre, 2018
Afrique

Mining is an important source of revenue for many developing countries, however, the social, environmental and economic impacts of mining are often poorly monitored. The recent transition of a gold mine in Western Tanzania—from large-scale gold mine under private, multinational ownership, to medium-scale public and national owned mine with limited life length offers a prime opportunity to understand the implications of changes in ownership and scale on the local economy and community well-being.

Scale-appropriate mechanization impacts on productivity among smallholders: Evidence from rice systems in the mid-hills of Nepal

Peer-reviewed publication
Mai, 2019
Népal
Asie méridionale

Smallholder farmers in the mid-hills of Nepal are facing an acute labor shortage due to out-migration which, in general, has affected the capacity to achieve timely crop establishment, harvest, and inter-cultural operations. These effects are more visible in the case of labor-intensive crops such as rice and promoting higher levels of rural mechanization has emerged as the primary policy response option. Nevertheless, quantitative evidence for the ability of mechanization to offset the adverse effects of shortages increasing labor prices in these systems is largely absent.
