Agriculture and Innovation in the Urban Fringe: The Case of Organic Farming in Quebec, Canada

Abstract: This paper presents the urban fringe as an area where alternative forms of agriculture, i.e. organic farming, are favoured through closer access to such resources as a large urban market and specialised agricultural services. An analysis of organic farming in Quebec, Canada, shows that urban fringe areas account for the highest level of activity in organic farming compared to other regions, confirming the presence of conditions encouraging innovation. Concentrations of organic farming are also present within urban fringe areas, suggestive of other factors, e.g. the role of local actors, which also influence the development of alternative and innovative forms of agriculture.

Reduced Tillage and No-Till in Organic Farming Systems, Germany—Status Quo, Potentials and Challenges

Abstract: Only 34% of all German farms apply reduced tillage (RT), while approximately 1% of the arable land is under no-tillage (NT). Statistics for organic farming are not available, but the percentages are probably even lower. The development of German organic RT and NT has been strongly driven by pioneer farmers for 40 years, and supported by field trials since the 1990s. The main motive for conversion to RT is increased soil quality, followed by reduced labor costs. NT combined with high-residue cover crops plays only a very small role. Rather, German organic farmers resort to shallow ploughing, a reduced number of ploughing operations in the rotation and/or substitution of the ploughing with non-inversion tillage. In field trials, winter wheat (Triticum aestivum L.) yields were reduced up to 67% by using RT methods compared to inversion tillage treatments due to reduced mineralization and increased weed pressure, both of which are major obstacles that impede the wider adoption of RT and NT by German organic farmers. Improvement of NT and RT (rotations, implements, timing) in organic farming is a task of both agricultural practice and science. A number of conventional farmers who have recently converted to organic farming are already familiar with RT. These farmers will act as a thriving factor to implement their experience after conversion and contribute to further innovations of RT in organic farming.

Climate change and organic agriculture.

Abstract: This paper attempts to explore some research findings focusing on the climate change impact on (organic) agriculture and agriculture impact on climate change through a literature review. This review reveals that climate change and agriculture are closely linked and interdependent. Compared to conventional agriculture, organic agriculture is reported to be more efficient and effective both in reducing GHGs (CO 2 , CH 4 and N 2 O) emission mainly due to the less use of chemical fertilizers and fossil fuel. Organic agriculture also reported to be climate change resilience farming systems as it promotes the proper management of soil, water, biodiversity and local knowledge there by acting as a good options for adaptation to climate change. But, due to lack of proper research, the contribution of organic agriculture for climate change adaptation and mitigation is yet to be known in the Nepalese context. It is argued that organic agriculture positively contributes to offset negative impacts of climate change, but there is inadequate systematic data to substantiate this fact.

The Farmer Within an Institutional Environment. Comparing Danish and Belgian Organic Farming

Abstract: This article is about variation in the expansion of organic farming sectors in different countries. It is suggested that variations in the absolute expansion of organic farming may be understood through a theoretical framework emphasizing the importance of the quality of the interrelationships among national institutions within organic farming as well as between organic and conventional agriculture. The theoretical proposition is illustrated by comparing the development in the institutional environment of organic farming in Denmark and Belgium from 1985 to 1999. In the Belgian case, the organic farming sector has expanded slowly due to an institutional environment of organic farming that has developed along regional lines and detached from the institutions of conventional farming. This development is seen as a result of an interrelationship characterized by pure competition where very little dialogue appears between organic and conventional farming. In the Danish case the organic farming sector has expanded throughout the period as a result of a series of creative conflicts, both within the organic farming sector and between the organic and conventional farming sectors.

Organic grain cropping systems to enhance ecosystem services

Abstract: Organic grain cropping systems can enhance a number of ecosystem services compared with conventional tilled (CT) systems. Recent results from a limited number of long-term agricultural research (LTAR) studies suggest that organic grain cropping systems can also increase several ecosystem services relative to conventional no-till (NT) cropping systems: soil C sequestration and soil N fertility (N mineralization potential) can be greater while global warming potential (GWP) can be lower in organic systems that use animal manures and cover crops compared with conventional NT systems. However, soil erosion from organic systems and nitrous oxide (N2O, a greenhouse gas) emissions from manure-based organic systems appear to be greater than from conventional NT systems, though data are limited. Also, crop yields, on average, continue to be lower and labor requirements greater in organic than in both tilled and NT conventional systems. Ecosystem services provided by organic systems may be improved by expanding crop rotations to include greater crop phenological diversity, improving nutrient management, and reducing tillage intensity and frequency. More diverse crop rotations, especially those that include perennial forages, can reduce weed pressure, economic risk, soil erosion, N2O emissions, animal manure inputs, and soil P loading, while increasing grain yield and soil fertility. Side-dressing animal manures in organic systems may increase corn nitrogen use efficiency and also minimize animal manure inputs. Management practices that reduce tillage frequency and intensity in organic systems are being developed to reduce soil erosion and labor and energy needs. On-going research promises to further augment ecosystem services provided by organic grain cropping systems.
