Rice farming sustainability assessment in Bangladesh

Journal Articles & Books
December, 2014
Bangladesh

Farming sustainability is primordial to long-term socioeconomic development. This study assesses rice farming sustainability in Bangladesh by developing a composite indicator (CI) under the four pillars of sustainability and examines the main determining factors. The assemblage of top-down and bottom-up approaches were applied to generate an essential set of indicators and data were collected through a household survey from 15 villages of three major rice growing ecosystems.

Conservation begins after breakfast: The relative importance of opportunity cost and identity in shaping private landholder participation in conservation

Journal Articles & Books
December, 2013

The conservation opportunity literature increasingly emphasises opportunity cost as an important determinant of willingness to engage in conservation on private land. We investigated the explanatory power of a group of opportunity cost variables in the decision to participate in a landscape-level conservation initiative on the Agulhas Plain, Cape Floristic Region. Opportunity cost variables outperformed affiliation and demographic variables when used in one model and had almost as much explanatory power as the combined model when used on their own.

Assessment of status and trends of olive farming intensity in EU-Mediterranean countries using remote sensing time series and land cover data

For EU-Mediterranean olive groves (Olea europaea), mapped in CORINE, classes of olive farming intensities were derived from the outcome of a multi-temporal remote sensing vegetation dynamics analysis. The management intensity classes were developed in view of a differentiated accounting of olive groves when delineating High Nature Value Farmland areas (HNV) at pan-European level. The remote sensing input data used was the Green Vegetation Fraction (GVF), derived in 10-day intervals from a long-term time series of NOAA AVHRR data.

Food sovereignty, food security and democratic choice: critical contradictions, difficult conciliations

Journal Articles & Books
December, 2014

In recent years, the concept of ‘food sovereignty’ has gained increasing ground among grassroots groups, taking the form of a global movement. But there is no uniform conceptualization of what food sovereignty constitutes. Indeed, the definition has been expanding over time. It has moved from its initial focus on national self-sufficiency in food production (‘the right of nations’) to local self-sufficiency (‘the rights of peoples’). There is also a growing emphasis on the rights of women and other disadvantaged groups, and on consensus building and democratic choice.

Indices of bird‐habitat preference from field surveys of birds and remote sensing of land cover: a study of south‐eastern England with wider implications for conservation and biodiversity assessment

Journal Articles & Books
December, 2005

Aim This paper describes the development of novel indices of bird‐habitat preference to examine bird species’ use of habitats and their distributions relative to habitats. It assesses the implications for bird conservation regionally and the scope for biodiversity assessments generally. Location A 200 km by 400 km area of farmland with seminatural and urban areas, covering south‐eastern England. Methods Cluster analysis was used to link birds to landscapes. Cluster centroid coordinate values were processed to derive indices of bird‐habitat preference.

Buntings (Emberizidae) as indicators of HNV of farmlands: a case of study in Central Italy

Journal Articles & Books

Europe

Farmlands represent one of the most important habitats for several bird species in Europe, but during the last few decades, agricultural landscapes have been subject to a rapid and large-scale change, caused by the intensification and mechanization of agricultural activities, that is one of the main drivers of worldwide biodiversity decline.

marginal product value of irrigation water for potato and vine cultivation in the Sandveld region, South Africa

Southern Africa

The advent of grid electrification in the Sandveld region of South Africa in the 1980s increased the utilisation of groundwater resources for commercial irrigation purposes. In the wake of the consequent increased pressure on the resource, it behooves landowners to use water more productively and responsibly. This paper calculated the marginal product value (MPV) of irrigation water for potatoes and vine production in this region to assess and to allow the comparison of the productivity of irrigation water with other commodities and regions.

Research on landscape ecological security pattern in a Eucalyptus introduced region based on biodiversity conservation

Journal Articles & Books
December, 2015
China

Landscape fragmentation and habitat loss are one of the important factors resulting in biodiversity decrease and species extinction. A large amount of Eucalyptus have been introduced into Yunnan Province in China since 2003, replaced the native forest, farmland, wasteland and other ecosystems, leading to natural habitat loss and landscape fragmentation.

Simple models of carbon and nitrogen cycling in New Zealand hill country pastures: exploring impacts of intensification on soil C and N pools

Journal Articles & Books
December, 2011
New Zealand

Concerns about climate change and water quality make it necessary to have a better understanding of the cycling of carbon (C) and nitrogen (N) within landscapes. In New Zealand, pastoral farming on hill country is a major land use, and there is little information available at a landscape level on the cycling of C and N within these systems, particularly the impacts of land use intensification.
