agriculture land Articles

The expansion of agricultural land use has been associated with the loss of environmental amenities, such as biological diversity, ecosystem services, and aesthetic values. Here, the determinants of agricultural land use are examined, drawing on panel data from 121 countries over the period 1965–1987. The analysis finds that an inverted U curve (or "environmental Kuznets curve") describes the ...

A long narrow strip of land (no more than 430 km wide) between the Andes and the Pacific Ocean, Chile stretches 4,630 km from near lat. 18°S to Cape Horn (lat. 56°S), including at its southern end the Strait of Magellan and Tierra del Fuego, an island shared with Argentina. In the Pacific Ocean are Chile's several island possessions, including Easter Island, the Juan Fernández ...

Recent distressing trends in climate change, population explosion and deforestation have inspired this paper, which completes the existing literature by providing empirical justification to hypothetical initiatives on the impact of population growth on forest sustainability in Africa. Using three instruments of forest exploitation, the study shows how rural, agricultural and national population ...

The main objective of this paper is to carry out Multi-Criteria Decision Making (MCDM) to arrive at the best alternative by accounting for uncertainties and spatial variability in the various elements. The present paper focuses on addressing uncertainty in the process of land suitability evaluation for horticultural projects area (mountains area in Syria). In this context, both fuzzy AHP and ...

Runoff disregards territorial boundaries, affects farmers as well as other users of space, and necessitates collective action if it is to be combatted. In this article, based on the case of Upper-Normandy, we show that geographical proximity can play a determining role in the struggle against erosive runoff, and we present a new tool for analysing relations of proximity between farmers. First, we ...

Received for publication January 27, 2009. In the southwestern agricultural region of Western Australia, the clearing of the original perennial vegetation for annual vegetation-based dryland agriculture has lead to rising saline groundwater levels. This has had effects such as reduced productivity of agricultural land, death of native vegetation, reduced stream water quality and infrastructure ...

This risk assessment applied a framework for determining probable co‐occurrence of juvenile spring Chinook salmon (Oncorhynchus tshawytscha) with agricultural pesticides in the Willamette Basin, Oregon (Teply et al. this issue) to characterize risk to the threatened population. The assessment accounted for spatial and temporal distribution of 6 acetylcholinesterase‐inhibiting insecticides in ...

Smallholders in many tropical highlands cause serious environmental damage. The Cameron Highlands of Malaysia offer an excellent opportunity for studying how farmers interact with environment, changing markets, infrastructure development, indigenous peoples, and tourism, and how these shape innovation. Our surveys in 2002-2004, 2006 and 2007 show that farmers have intensified production and in ...

Estuarine eutrophication as a result of agricultural land use including the use of chemical fertilizers is increasing worldwide. Prince Edward Island, Canada has very high agricultural intensity by international standards with approximately 44% of the land area under production, and some watersheds in excess of 75% agricultural land‐use. The type of agriculture is also intensive with primarily ...

A number of policy tools are used to reduce soil erosion from agricultural lands in the USA, including education and technical assistance, financial assistance, land retirement, and conservation compliance requirements. Education and technical assistance by public and private sources can be effective in promoting the adoption of conservation tillage by farmers for whom that practice will be ...

Most catchments discharging into the Great Barrier Reef (GBR) lagoon have elevated loads of suspended sediment, nutrients, and pesticides, including photosystem II inhibiting herbicides, associated with upstream agricultural land use. To investigate potential impacts of declining water quality on fish physiology, RNASeq was used to characterize and compare the hepatic transcriptomes of ...

We examined the influence of riparian vegetation on macroinvertebrate community structure in streams of the Upper Thames River watershed in southwestern Ontario. Thirty-three µ-basins (129–1458 ha) were used to identify land cover variables that influenced stream macroinvertebrates. Micro-basins represented the entire drainage area of study streams and were similar in stream order (first, second) ...

Received for publication January 3, 2008. Streams and rivers are a globally significant source of nitrous oxide (N2O), a potent greenhouse gas. However, there remains much uncertainty in the magnitude of N2O emissions from these sources, partly due to an incomplete understanding of the factors that control microbial N2O production in lotic sediments. During 2004–2005 we measured sediment N2O ...

The article presents findings of local experimentation for managing land degradation problems in swidden farming, and the institutional setting for such experimental activities within a resilience theory framework. By using action research (AR) methodology, which included in-depth interviews and joint field experiments, the research process facilitated collective learning related to land ...

We describe the prevalence and severity of intersex in the form of testicular oocytes (TO) in largemouth bass (Micropterus salmoides; LMB) collected over a 5 yr period from a variety of surface waters on the Delmarva Peninsula, USA, a region dominated by poultry production and agricultural land‐use. During a 2005–2007 survey of approximately 200 male specimens representing 6 fish and 2 frog ...

The impact of vegetative filter strips to reduce the delivery of nonpoint source pollutants from agricultural land to inland water systems is now recognized as an important element in overall agro-ecosystem management. A glasshouse experiment was undertaken to measure the effectiveness of tree (Eucalyptus camaldulensis Dehnh. and Casuarina cunninghamiana Mq.) and pasture filter strips to ...

The 'Measured Annual Nutrient loads from AGricultural Environments' (MANAGE) database was developed to be a readily accessible, easily queried database of site characteristic and field-scale nutrient export data. The original version of MANAGE, which drew heavily from an early 1980s compilation of nutrient export data, created an electronic database with nutrient load data and corresponding site ...

Introduction: Delta, British Columbia is located in the Fraser River delta on the shores of the Pacific Ocean, just south of the City of Vancouver. Delta comprises mostly agricultural land, with typical ground elevations near sea level. Levees protect the area from potential floods from the Fraser River and tidal surges from the Pacific Ocean. Of the 13,500 hectares (ha) ...

Multifunctionality of Agriculture (MFA) is a concept that supports the recognition of complex interdependencies between different resources, production processes and outputs of agricultural land use. Political decision making within a sustainable development frame requires extensive information about these interrelationships in order to analyse the impact of implemented policies and to assess ...
