Chicken slaughterhouse
Country: U.S. Problem: Poor final effluent quality Product: BFL 5100HP Background A chicken slaughterhouse was killing 10,000 chickens per day. Final effluent was discharged to a stream. The final effluent COD was exceeding the discharge limit of 100mg/L and as a result it had to be tankered off site and spread on agricultural land. Obviously this was costly and not sustainable as a medium to ...

Asia–Pacific Analysis: Plan for growth in biotech crops
South-East Asian nations should follow the Philippines down the path to biotech crops for food security, argues Crispin Maslog. Since biotechnology-derived crops were introduced in 1996, they have been adopted at an unprecedented rate, according to the 2011 annual report of the International Service for the Acquisition of Agri-biotech Applications (ISAAA) released earlier this year. [1] There ...

Model forecasts long-term impacts of forest land-use decisions
The drive to develop crops for use as biofuel, continues to raise questions about additional uses of forest land. A cutting edge computer model developed at North Carolina State University offers detailed insight to predict the environmental impact – along with understanding forest ecosystem response to global climate change. “We think the model will help policy makers and forest ...

Delta drainage and irrigation system, complex multifunction hydraulic system analysis - Case Study
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) watershed, 6,300 ha is ...

Application of nitrogen and phosphorus criteria for streams in agricultural landscapes
Efforts to control eutrophication of water resources in agriculturally dominated ecosystems have focused on managing on-farm activities to reduce nutrient loss; however, another management measure for improving water quality is adoption of environmental performance criteria (or ‘outcome-based standards’). Here, we review approaches for setting environmental quality criteria for nutrients, ...

Assessing agroforestry`s advantages
Agroforestry, the deliberate placement of trees into crop and livestock operations, can help capture substantial amounts of carbon on agricultural lands while providing production and conservation benefits. However, we currently lack tools for accurately estimating current and projected carbon values in these systems. In North America, windbreaks are an effective carbon-capturing option. Only ...

Current use valuation programs: property tax incentives for preserving local benefits of forests
Summary This paper explores current use valuation programs as one tool for conserving and fostering sustainable management of southern U.S. forests under private ownership. The brief identifies key constraints on existing programs and suggests measures that could be implemented to enhance program effectiveness. As a result of rising property taxes on lands under development pressure, ...

New forms of local collective governance linked to the agricultural landscape: identifying the scope and possibilities for hybrid institutions
Over the last few years, there has been a significant increase in the focus on rural development and public goods within the common agricultural policy (CAP). Many researchers emphasise how this implies a need for new ways of implementing policy and innovative collaboration between various actors. Policymakers also acknowledge such needs. Local action groups and organisations have a significant ...

Survey of lanthanoids in plants from a tropical region
Several anthropogenic sources may provide lanthanoids (La, Ce, Nd, Sm, Eu, Tb and Yb) to the agricultural and forestry landscapes. Because little information is available on the distribution of these chemical elements in Brazilian tropical ecosystems, this work focuses on the survey in leaves of diverse plant species (native trees, epiphytes and crops) from different ecosystems. Soil under crown ...

New animal feed plant relies on proven sera dosing technology
Top animal feed is a result of the exact application of composition during the production process as well as the use of stateof-the-art technology. The correct planning of the systems engineering is as important as the experience of the staff in the production department. When the Rothkötter animal feed plant was built in Haren-Hüntel, the company relied on sera – a name widely ...

Export and import of virtual water from different states of India through food grain trade
The geographical area of India is 3.29 × 106 km2 and the annual average precipitation is about 4000 km3 (about 1215 mm depth over the country). Large variations in agricultural practices, climate and land productivity result in large variations in agricultural productivity between states. Virtual water refers to the water required in the production of goods or services; exchange of water through ...

Nitrogen recovery from source-separated human urine using clinoptilolite and preliminary results of its use as fertilizer
The use of source separated human urine as fertilizer is one of the major suggestions of the new sanitation concept ECOSAN. Urine is rich in nitrogen, phosphorus and potassium which act as plant nutrients, however its salinity is high for agricultural and landscape purposes. Moreover, characteristics change significantly throughout storage where salinity increases to higher values as the ...

Land and pastoralism: New South Wales Riverina
The Riverina region in south-western New South Wales, Australia, is a discrete geographical area having unique patterns of soils and vegetation. During 170 years, it has been used productively for sheep and cattle grazing, but with significant detrimental impact on the natural systems. This article reviews the historical impact and suggests means of rehabilitating the landscape for the purposes ...

Critical source area management of agricultural phosphorus: experiences, challenges and opportunities
The concept of critical source areas of phosphorus (P) loss produced by coinciding source and transport factors has been studied since the mid 1990s. It is widely recognized that identification of such areas has led to targeting of management strategies and conservation practices that more effectively mitigate P transfers from agricultural landscapes to surface waters. Such was the purpose of P ...

Accounting for the market and non-market values of multifunctional outputs in evaluating water transfers to non-agricultural uses: empirical evidence from Taiwanese rice production
Increased demand for water for municipal and industrial uses throughout Taiwan has intensified the pressure to re-allocate water from agricultural to non-agricultural uses. The full policy implications of such water transfers must not only account for the value of lost agricultural production and income, but also any loss in the social value of multifunctional benefits from agricultural ...

The emergence of urban agriculture: Sydney, Australia
Across the world the phenomenon of urban agriculture (UA) is defining itself after emerging from a mainly grass-roots response, evidenced in the Sydney Metropolitan Region by the Hawkesbury Harvest phenomenon and the Sydney Food Fairness Alliance, to powerful global forces which are negatively and paradoxically impacting on the quality of life of urban and farming communities. In the developed ...
