Lg Sonic Ultrasonic Algae and biofilm control for irrigation case study
Water used for irrigation can contain high levels of nutrients, some of these nutrients are beneficial for the plants watered, but can also lead to extensive algal growth. Algae in irrigation tanks can clog the irrigation system and can also be spread over the irrigated area. In addition, some types of fungus, also present in these waters, can be harmful for the plants grown. Therefore the ...

The sustainability challenge: Meeting the needs of the water-energy nexus
In 2009 Davos World Economic Forum reported that the world is quickly heading towards “water bankruptcy.” As global population soars, food, energy and freshwater are becoming increasingly scarce. Water, whether for potable or industrial use, is limited, and some supplies are not useable. The need for water in the developed world is high. Two-thirds of all the water consumed is used ...

How can we create jobs, reduce food prices and boost economies?
The fate of heads of state across the globe is tied in large part to their ability to ensure employment, economic growth, and access to cheap food and clean water. Rising food prices have helped topple dictators across the Middle East. Europe, the United States, Japan and other major economies are spending trillions of dollars to restore growth and jobs. Too often, efforts to address ...

Flood risk for farmer and dyke relocation
The Biosphere Reserve Lower Saxonian Elbe Valley (Biosphärenreservat Niedersächsische Elbtalaue), which was created on the basis of an unanimous decision by the Lower Saxonian State Parliament in 2002, represents Lower Saxony’s contribution to the UNESCO Biosphere Reserve ‘Flusslandschaft Elbe’ (Elbe River Landscape). It stretches for about 100 kilometres south-east of ...

Funding for forests: the potential of public ballot measures
A variety of measures exist to prevent deforestation or forest conversion to other land uses. Some of these measures, such as purchasing land outright for conservation or purchasing conservation easements, are designed to permanently protect forests by precluding future residential or commercial development on the tract of land. But these approaches all require money. One approach to raising ...

Re-coupling the carbon and water cycles by Natural Sequence Farming
The techniques of Natural Sequence Farming (NSF) were developed during hands-on management of degraded farmland in the Upper Hunter Valley region of Australia. Early settlement of the continent by people with European cultural assumptions disrupted established interactions of water, soil, and plants resulting in lost fertility. Moreover, agricultural practices such as clearing, burning, ...

Farmland Abandonment in the EU: an Assessment of Trends and Prospects
Over recent decades substantial areas of the EU have been affected by agricultural abandonment (ie. the complete withdrawal of agricultural management such that natural succession processes are able to progress). This is largely a result of declines in the viability of extensive (low input) and small-scale agriculture systems. Therefore such abandonment threatens a range of semi-natural habitats ...

10 messages for 2010 - agricultural ecosystems
Introduction: biodiversity, agriculture and the Common Agricultural Policy (CAP) Europe"s agricultural sector has received sustained public support under the Common Agricultural Policy (CAP) over the last 50 years. This support has evolved alongside growing recognition and awareness of the strong links between agricultural production and biological diversity conservation. On one hand, it ...

The multifunctional use of urban greenspace
This paper calls attention to the critical role of greenspaces in cities, while it overviews the many functions they provide. From a theoretical perspective, the utility function of urban greenspaces concerns multiple dimensions. Temporal, spatial and social aspects clearly need a taxonomic approach, which is also described in this study. Thus, the prominent goal of this paper is to highlight the ...

The CAMBI process and agriculture, a sustainable solution?
Abstract Both public acceptance and interest from farmers for spreading biosolids from waste water treatment plants (wwpt) on arable land, are dependent on some fundamental criteria. These criteria are, however, quite straightforward. The biosolids should be safe, easy to handle, a well documented source of plant nutrition, without disagreeable odours and easily available. A big part of the ...

Effect of tillage and rainfall on transport of manure-applied cryptosporidium parvum oocysts through soil
Received for publication September 30, 2008. Most waterborne outbreaks of cryptosporidiosis have been attributed to agricultural sources due to the high prevalence of Cryptosporidium oocysts in animal wastes and manure spreading on farmlands. No-till, an effective conservation practice, often results in soil having higher water infiltration and percolation rates than conventional tillage. We ...

Mineral-nitrogen leaching and ammonia volatilization from a rice–rapeseed system as affected by 3,4-dimethylpyrazole phosphate
Received for publication November 9, 2008. 3,4-Dimethylpyrazole phosphate (DMPP) was validated as an effective nitrification inhibitor to reduce nitrate leaching. Its effects on ammonia (NH3) volatilization were not clear, especially on farmland scale with crop rotations. In this study, on-farm experiments at the Jiaxing (JX) and Yuhang (YH) sites in Taihu Lake Basin, China were conducted to ...

Mitigation options for sediment and phosphorus loss from winter-sown arable crops
Received for publication January 20, 2009. Sediment and P inputs to freshwaters from agriculture are a major problem in the United Kingdom (UK). This study investigated mitigation options for diffuse pollution losses from arable land. Field trials were undertaken at the hillslope scale over three winters at three UK sites with silt (Oxyaquic Hapludalf), sand (Udic Haplustept), and clay (Typic ...

Recently planted vegetation strips reduce Giardia runoff reaching waterways
Current methods for tracking pathogens across farmland and into surrounding waterways via runoff are limited and typically have been developed using artificially created landscapes. No studies have investigated how Giardia in farm runoff moves across the landscape, despite high prevalence rates in dairy cattle (Bos taurus) worldwide. Here, we report the development of a field-based tracking ...

Molecular epidemiology of campylobacter jejuni populations in dairy cattle, wildlife, and the environment in a farmland area
We describe a cross-sectional study of the molecular epidemiology of Campylobacter jejuni in a dairy farmland environment, with the aim of elucidating the dynamics of horizontal transmission of C. jejuni genotypes among sources in the area. A collection of 327 C. jejuni isolates from cattle, wildlife, and environmental sources in a 100-km2 area of farmland in northwest England was characterized ...

Scale of biomass production from new woody crops for salinity control in dryland agriculture in Australia
There is scope internationally to utilise surplus and degraded agricultural land for biomass crops that might also be environmentally beneficial. For example, dryland salinity in southern Australian could be ameliorated using profitable woody biomass crops. A model was developed to predict biomass production from such woody crops. At a biomass price of A$35/t (green) and a water use efficiency of ...

Rural transformation in Turkey 19802004: case studies from three regions
This paper focuses on the economic dimension of rural transformation (or structural transformation) in Turkey. It investigates the development of labour demand and supply in rural areas over the past two decades. For that purpose, three longitudinal case studies were conducted in three different regions of Turkey. This paper concludes that the lack of substantial labour transfer from agricultural ...

CORNucopia of Opportunity in the Heartland: Or Just More Feed for the Political Cattle?
We now live in a carbon constrained world. Fears of human induced climate change are bringing about changes in government, corporate and consumer behaviors. Investments in renewable energy are increasing, corporations are greening everything from their supply chain to their vehicle fleet, and consumers are seeking to minimize their ecologic footprint as well. Are some of our greening efforts ...

Hedonic analysis of farmland prices: the case of Aragon
A hedonic approach is used to study farmland prices in Aragon (Spain). Data over 450 transactions in 33 shires, in 2001 and 2002 are analysed. The marginal values for irrigated vs. non-irrigated land, the productive orientation and the differentiation of production through a Designation of Origin (D.O.) are used as explanatory variables. Socio-economic variables are also included. A Box-Cox ...
