<--break->The topic of a special issue of the journal Agroecology and Sustainable Food Systems addresses “Agroecology and the Transformation of Agri-Food Systems.” Look for Steve’s article, “Agroecology: Growing the Roots of Resistance,” here.

Article abstract: 

Agroecology today has a strong focus on bringing sustainability to food, feed, and fiber production. But there is also a larger focus on the social, economic, and political “drivers” that move food systems beyond the conditions that have created un-sustainability in modern industrial agriculture. With its ecosystem foundation, the science of agroecology has become a powerful tool for food system change when coupled with an understanding of how change occurs in society. In this article, I trace the roots of agroecology to its emergence as Agroecología in Mexico in the 1970s as a form of resistance to the Green Revolution. Agroecology has become much more than a science for developing better, safer, and more environmentally sound food production technologies. Agroecology is more than a way to practice agriculture, such as organic or ecological production. Agroecology is also a social movement with a strong ecological grounding that fosters justice, relationship, access, resilience, resistance, and sustainability. Agroecology seeks to join together the ecological and social cultures that helped human society create agriculture in the first place.

<--break->The topic of a special issue of the journal Agroecology and Sustainable Food Systems addresses “Agroecology and the Transformation of Agri-Food Systems.” Be sure to read the introductory article, “Agroecology as a Transdisciplinary, Participatory and Action-Oriented Approach,” co-authored by CAN researchers Ernesto Méndez and Christopher Bacon and CAN assistant director Roseann Cohen. Find the article here.

Article abstract:

This article traces multiple directions in the evolution of agroecology, from its early emphasis on ecological processes in agricultural systems, to its emergence as a multidimensional approach focusing on broader agro-food systems. This review is timely, as agroecology is being increasingly applied within a diversity of scientific-, policy-, and farmer-based initiatives. We contrast different agroecological perspectives or “agroecologies” and discuss the characteristics of an agroecology characterized by a transdisciplinary, participatory and action-oriented approach. Our final discussion describes the contents of the special issue, and states our goal for this compilation, which is to encourage future work that embraces an agroecological approach grounded in transdisciplinarity, participation, and transformative action.

Influence of sediment on the growth of the invasive macrophyte Najas marina ssp. intermedia in lakes

Available online 22 December 2012
Publication year: 2012
Source:Limnologica – Ecology and Management of Inland Waters

Najas marina ssp. intermedia (Wolfg. ex Gorski) Casper ( Najas intermedia ) is a thermophile macrophyte species native to Central Europe, which started mass spreading across Southern Germany about 10 years ago, almost reaching the intensity of the invasive neophyte Elodea nuttallii . As part of a study to examine the spread of N. intermedia with regard to climate change, predominant populations of N. intermedia were continuously monitored. The observations revealed that some areas and lakes remained free of N. intermedia , although water temperatures and light conditions were similar to locations with predominant populations of N. intermedia . As a result, growth experiments were conducted to show that the properties of the lake sediment can affect the growth of N. intermedia . Four lakes without populations of N. intermedia and with different environmental conditions were chosen as experimental sites. During the experiments eight different sediments from four different lakes were used. Five sediments were collected from sites with extensive or predominant Najas populations, three sediments originated from locations with no or minor amounts of N. intermedia . The experiments revealed that the sediment from different lakes as well as from different locations within the same lake significantly differs in nutrient concentration and density and that those differences can affect the growth of N. intermedia . Plants growing in nutrient-rich sediment (SRP: 15 mg 100 g−1 soil, Total-P: 50 mg 100 g−1 soil) reached with 43.1 (±6.9) mm day−1, compared to 6.9 (±2.0) mm day−1 in sediment with lower nutrient concentrations (SRP: 2 mg 100 g−1 soil, Total-P: 10 mg 100 g−1 soil), higher growth rates and were less affected by the density of the sediment. The density of the sediment, on the other hand, played a significant role under conditions with low nutrient concentrations, respectively when sediments with similar nutrient concentrations were compared. For example, a comparison of sediments with a soluble phosphor concentration of 2 mg 100 g−1 soil and a total phosphor concentration of 10 mg 100 g−1 soil showed that plants growing in sediment with 75.7% particles > 0.063 mm reached twice the growth rates (6.9 ± 2.0 mm day−1) than plant growing in sediment with only 47% particles >0.063 mm (1.7 ± 0.6 mm day−1). Nutrient-poor sediment (SRP: <1 mg 100 g−1 soil, Total-P: <1 mg 100 g−1 soil), inhibited the growth of N. intermedia (0.8 ± 0.2 mm day−1). The significantly different growth rates of N. intermedia show that the lake sediment, respectively the nutrient concentration and density must be included in assessments and models regarding the growth and spread of N. intermedia .

A comparative study of macrophyte species richness in differently managed shore stretches of Lake Peipsi

Available online 21 December 2012
Publication year: 2012
Source:Limnologica – Ecology and Management of Inland Waters

We have compared the floristic composition of managed (M) and wild (W) shore areas in the northwestern, eutrophic part of Lake Peipsi (3555 km2, with unregulated water levels). Management techniques include uprooting or cutting of reeds and willows, building a terraced area between the dunes and the water edge and frequent mowing. In 2006 and 2008, macrophyte species richness was registered summarily for different shore stretches; in 2009–2010, a study on 12 transects, each with 10–15 quadrats of 0.5 m × 0.5 m, was carried out in the same area. In parallel to this, the vegetation in an overgrown inlet near the lake was studied. The aims were: (1) to estimate species richness on managed and wild shore areas and to determine the suitability of managed areas for maintaining declining species and (2) to study the impact of terrace building and duration of management on the vegetation. In total, 116 herbaceous species were found during the study period. Xero-, meso- and hygrophilous apophytes were characteristic for M (managed) stretches and hydrophilous apophytes for W (wild) stretches. Small threatened amphibious plants and hygrophytes such as Alisma gramineum , Ranunculus reptans , Sagina nodosa , Cyperus fuscus , Eleocharis spp., Juncus spp. were characteristic for the M stretches. The number of species was the highest (average per quadrat 11) in the mowed intermediate zone between the terrace and open water. In the inlet area the number of protected plants was highest in the first study year (2006) and then declined from 5 to 2. The highest total number of species was found in areas under ownership with diverse M and W habitats. Jaccard’s similarity coefficients (JSCs) for the whole study area between the years were 0.30–0.50. The calculation of 462 JSCs among all ownerships and transects for the study period yielded floristic similarities of 0–0.59. The year along with style of management seemed to have strongest relationship with higher JSCs, and the yearly changing water levels the most obvious reason for the changes. This study has revealed the contribution of active management towards the support of persistent species richness in conditions of changing water levels, but probably not supporting richness at the more stable water edge.

Powerful community

A word that comes up over and over in our work is community. I’ve been reflecting on various physical and virtual communities here at PAN, and the ways in which our lives and aspirations are woven together around our shared goals.

Looking at PAN’s accomplishments over the past year, I’m feeling deeply grateful to each and every person in these communities — including you, Dear Reader. Be they a handful of people or hundreds of thousands with common concerns, these overlapping communities provide the inspiration and the muscle we need to transform corporate and government systems.

Soil-building success stories!

The adage "we are what we eat" supports  food and nutrition education programs across the country. The same goes for the farm — production of an abundant diversity of healthy crops depends on healthy soil and crop management techniques.

Farmers aren't born knowing how to do this, they learn. They learn from each other, and through programs like USDA's new soil health initiative. This is why we're working hard to make sure the next Farm Bill is a strong one that supports innovative farmer education.

Light conditions and photosynthetic efficiency of phytoplankton in Murchison Bay, Lake Victoria, Uganda

Available online 20 December 2012
Publication year: 2012
Source:Limnologica – Ecology and Management of Inland Waters

Eutrophication has increased in the tropical Lake Victoria during the last decades, leading to problems of toxic algal blooms, oxygen depletion, and reduced water visibility. To better understand the mechanism behind this negative development, more knowledge on the coupling between optical properties and photosynthetic efficiency is needed. Here we present such data from Murchison Bay during the period December 2009–March 2010. Photosynthetic efficiency was measured as photochemical energy quantum conversion efficiency ( F ′ q / F ′ m ) and functional absorption cross-section ( σ ′ PSII ) by applying the Fast Repetition Rate Fluorometry (FRRF) technique. With chlorophyll- a concentrations between 100 and 174 μg L−1, the vertical attenuation coefficient of photosynthetic active radiation (PAR) was found to be in the range 1.93–2.25 m−1. The FRRF parameters F ′ q / F ′ m and σ ′ PSII , as well as the dissolved oxygen, were found to vary with the physiochemical properties of the water column. The spectral light characteristics of the deeper parts of the water in Murchinson Bay were found to be favourable for growth of cyanobacteria due to the presence of phycobilins, which has typical absorption peaks between 565 and 620 nm. The light utilisation coefficient α B derived from the FRRF parameters was found to be within the same range as that obtained earlier using conventional methods for other bays in Lake Victoria. We conclude that eutrophication is still increasing in Murchison Bay, and that nitrogen limitation together with deep penetration of light within the 550–650 nm wavelength band seems to favour the dominance of cyanobacteria.

Management effects on water quality, sediments and fish production in extensive fish ponds in the Dombes region, France

Available online 20 December 2012
Publication year: 2012
Source:Limnologica – Ecology and Management of Inland Waters

In aquaculture, management practices such as supplementary feeding or fertilisation of water are generally considered to improve fish yield in ponds or shallow lakes. Nevertheless, in semi-natural systems where many ponds or lakes are situated in a cultural landscape, this is much less evident for certain fish farmers because fish production systems are often quite extensive, and fish production is only one economic activity among others for these fish farmers. In this paper we analyse the influence of different management practices on fish yield and nutrient status of fish ponds’ water and sediments, and we have an additional regard on potential implications of this in the perspective of the European Water Framework Directive. This directive demands that artificial water bodies such as fish ponds have to attain a good ecological potential in 2015, and thus to adapt water body management to achieve this. In total, 83 fish ponds were studied from 2007 to 2009 in the Dombes region, France. This region is characterised by 1100 nutrient rich fish ponds located in a heterogeneous agricultural landscape with cropping, animal husbandry and forestry. Different water parameters (PO 4 3−, NO 3 , total P, total N, NH4+, chlorophyll-a) were analysed from April to October in each year. Sediments were sampled in March and October and analysed for available P, total N, organic matter and Ca concentration. Data about pond management practices such as fertilisation of pond water, supplementary feeding as well as fertilisation and liming of pond grounds when they are emptied and let dried out during a year, and harvested fish were collected by interviewing pond owners and pond managers. The main results found are that the combination of the annual management practices supplementary feeding and fertilisation, increased significantly the fish yields. When combining the annual with the non-annual management practices fertilisation of pond grounds and liming of pond grounds during a year when ponds are emptied, highest yield were obtained. Using only the non-annual practices, yields could be positively influenced. Lowest yields were found when no management practice was applied. Significant, but contrasting effects of pond management practices on water or sediment parameters were only found for available P of sediments and NO 3 for the management practices supplementary feeding, fertilisation of water, or liming of the pond ground. Whereas available P of sediments showed higher values with the three practices, NO 3 in the water showed lower values. Although only few significant differences were found, means of parameters showed a certain trend as they were in many cases, besides for total N and NO 3 , higher with the management practice. Our results show that there is a limited effect of pond management practices on the chemical status of the pond water and sediments. This also suggests a limited potential to change management practices to respond to the demand of the European Water Framework Directive for good water quality and ecological potential.
