European food and agricultural strategy for 21st century
Production ecological analyses reveal great differences in food production potential and food requirement between global regions, which implies the need for redistribution of food between surplus and deficit regions. The surplus production potential, current production and trade volumes of Europe along with the desires of its society for non-food functions from its land, favours a dual ...

Knowledge-intensive technology in agricultural and rural contexts: relationships with sustainability
Knowledge-intensive technology can contribute a lot to the transformation of agriculture, also in terms of more eco-efficient and nonmaterial production. However, relatively little is known so far on the relationship of the development of ICTs and agriculture/rurality and the environment. This paper discusses key processes of information society that may contribute to the developments about to ...

The Effect of Off-farm Work on the Intensity of Agricultural Production
Changes in agricultural production methods have been associated with environmental pressure and a loss of natural habitats. This paper explores the extent to which farmer participation in off-farm work (an increasing phenomenon in most developed countries) changes the intensity of agricultural input use focusing, in particular, on fertilizer and crop protection product use. A sample selection ...

Groundwater nitrate and chloride trends in an agriculture-intensive area in southern Alberta, Canada
The potential effect of manure management from livestock production on groundwater quality is an issue of concern. Groundwater sampling from a regional transect in southern Alberta, Canada, was conducted to determine changes in groundwater quality with time. The study area has extensive irrigation and a high density of confined feeding operations. Nitrate-N (NO3−-N) and chloride (Cl−) ...

Intensity of Italy's agri–food trade with countries outside the EU Mediterranean
This paper aims to present a framework of trade relations between Italy and the countries of southern and eastern shores of the Mediterranean Sea. More specifically, using the indicators proposed in the analysis of international trade, we want to analyse the intensity of trade in agri–food products and the strength of trade ties between the bordering Mediterranean countries. The analysis of the ...

Farmers' (local and colonists) perceptions of environmental changes in the forest frontier of the upper Amazon, Peru
Amazon ecosystem degradation profoundly impacts life supporting processes of global importance such as climate regulation, as well as local conditions for livelihoods. In Peru's highland jungle, an expanding deforestation front of forest conversion to agriculture has vastly transformed the landscape. Small–scale farming, the main driver of forest degradation, and consequently household natural ...

Seasonal exposure of fish to neurotoxic pesticides in an intensive agricultural catchment, Uma‐oya, Sri Lanka: Linking contamination and acetylcholinesterase inhibition
The annual cultivation pattern in the Uma‐oya catchment in Sri Lanka is characterized by Yala and Maha rainfall periods and associated cropping. Two cultivation seasons were compared for pesticide residues: base flow, field drainage, and the runoff and supplementary sediment data for three sites in the catchment. Organophosphate and N‐methyl carbamate pesticide analysis confirmed a higher ...

The contribution of agricultural input industries to agricultural innovation
This paper presents an analytical framework to measure how farmers (i.e., primary agriculture) in countries at different stages of economic development absorb new technology by buying inputs from other industries. By combining information on the use of purchased inputs in primary agriculture (based on country-specific input±output matrices) with information on R&D intensities in the various ...

Evaluating cumulative effects of anthropogenic inputs in Prince Edward Island estuaries using the mummichog (Fundulus heteroclitus)
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 ...

Paradigms and paradoxes of agricultural risk governance
Essential requirements of council directives and legal provisions in medical feedstuffs are not satisfied in Germany. The 'Schweinemastskandal' (intensive pig breeding scandal) sheds light on the various stakeholders that exploit ambiguous EU regulatory control structures through the use of hazardous feeding stuff and prophylactic prohibited medication. This case helps the understanding of ...

Advances in phytoremediation
Phytoremediation has many proponents to treat widespread chemical contaminants in soil, water, and air. It is low-cost, eco-friendly, and doesn’t require complicated technology and infrastructure. As it is a new branch of science, it is necessary to understand the processes involved in the different methods of phytoremediation to advise decision-making for application of this technology. ...

Turning abandoned rice fields into mangroves
What do you do when mangroves fail to naturally recolonise abandoned rice fields in one of the most precious mangrove deltas of the world? Pieter van Eijk reports on a recent mission to Western Africa that paves the way for large-scale mangrove recovery through a so-called ‘ecological restoration’ approach. While small on a map, Guinea Bissau is one of the most sizeable mangrove ...

Introducing the technique of composting in a rural municipality in Chile
Waste management in Chile Until a few years ago there had been a lack in the supply of basic infrastructure needs like the supply of drinking water, sewage systems, electricity and communication in a lot of rural areas in Chile. With the advancing economic development further necessities have arisen. New objectives are the extended development of infrastructure, the conservation of natural ...

A comparison of the herbicide tolerances of rare and common plants in an agricultural landscape
Declining plant biodiversity in agroecosystems has often been attributed to escalating use of chemical herbicides, but other changes in farming systems, including the clearing of seminatural habitat fragments, confound the influence of herbicides. The present study introduces a new approach to evaluate the impacts of herbicide pollution on plant communities at landscape or regional scales. If ...

Complete guide to raising laying hens: organic or free range?
1. Introduction Laying hens are a key component of agriculture and animal husbandry around the world. These surprisingly versatile animals not only provide a protein-rich food source through their eggs, but also contribute to agricultural economics and sustainability through manure production and food waste reduction. In the modern context, raising laying hens has become a topic of great ...

Tree, Crop & Plant Stress – A Primer on Abiotic and Biotic Stressors
The natural conditions in which plants and trees grow are neither uniform nor controlled. Many changes or fluctuations, even if they are temporary, can have a negative impact on and stress plants. The factors which can lead to stress can be one of two types: abiotic or biotic. Stress can have serious repercussions on various phases of a plant’s growth and, ultimately, crop productivity. ...

Explaining differential sources of zoonotic pathogens in intensively-farmed catchments using kinematic waves
Surveys in streams draining intensively farmed catchments can, during flood events, indicate differential time-concentration patterns between a bacterial health-risk indicator (E. coli) and a major zoonotic pathogen that it seeks to indicate—Campylobacter. The indicator's peak concentration at a monitoring station can arrive ahead of the flood peak (the pollutograph leads the hydrograph), whereas ...

Spacers: How they have evolved and their role in efficient Drainage Systems for Hydroponic Agriculture (soil level and elevated gutter systems)
In 2014, Hydroponic Systems launched its first patented Spacer onto the market. Its main advantages include excellent aeration and elimination of the moisture accumulated between the substrates and the surfaces they rest on. Due to that, the Spacer quickly found expert grower’s approval. They appreciated that, when used, the Spacer avoided a number of issues and diseases across the ...
