Inheriting disease, one pesticide at a time

Epigenetic transgenerational inheritance. Say that again? Those three "little" words refer to environmental exposures causing genetic changes that can be passed on to future generations.

These effects appear to be transferred via modification of DNA — modifications that can sometimes increase the risk of disease. As a study released last week shows, the increased disease risk can keep showing up through multiple generations.

XV Annual International Agroecology Shortcourse | La Pita Community Visit Wrap-Up


La Pita Community Visit Wrap-Up

Our two-day visit to Denis Guiterrez Cooperative in the community of La Pita felt as though we had traveled to another world where campesino families opened their homes and their lives to us. Steve (Gliessman) and I had been here 18 months ago with the AgroEco® Coffee Tour and we were so impressed with the multitude of changes that have taken place since then. The crisis of “la roya” killing the coffee plants has deepened, but the community is responding with resilience. Not only are they replanting their coffee parcels, but the women’s group is making their own fertilizer to rebuild the soil. As part of CAN’s Food Security Project, youth leaders are working with the women’s group to plant home gardens to feed the families and to sell extra produce in a monthly Farmers Market.

There is a feeling of hope growing in La Pita as the families are improving their land and diversifying their crops and their income sources.

XV Annual International Agroecology Shortcourse | AgroEco® Coffee and La Pita


AgroeEco® Coffee and La Pita

AgroEco® Coffee Nicaragua comes from the farm families of La Pita. CAN and the roasters we work with are able to return more money per pound directly to the families. In addition, we’ve established two funds as part of AgroEco®:

(1) is a women’s fund that sets aside 5% of the payment for the women to use for agroecological projects they choose;

(2) a sustainability fund that sets aside another 5% for environmental projects in the community.

AgroEco® Coffee is a commitment to CAN’s long-term relationship with Denis Gutierrez and UCA San Ramón. It is not a certification, but instead a partnership with environmental and social changes measured through research every two years and shared with the farm families. AgroEco® Coffee is served at University of California Santa Cruz and Santa Clara University. It is roasted and available through Santa Cruz Coffee Roasting Company.

XV International Agroecology Shortcourse | Trip to La Pita


The La Pita Landscape

From a hill in the center of the community, one sees the landscape management. The top of the mountain is maintained as a reserve. In La Pita you can hear howler monkeys and many birds. Below the reserve the community grows corn and beans in family parcels. Coffee is grown below the trees surrounding the community. There is a two-room primary school that all of the children from pre-school through grade 6 attend. See photos.

The Heart of the Story — and a Hope as Well

La roya,” coffee rust, began showing up in the coffee parcels in significant amounts in 2012. It is throughout Nicaragua and much of Central America. When Steve (Gliessman) and I were in La Pita in February 2013 (with the AgroEco® Coffee Tour) we saw many plants infected and losing their leaves. There was still coffee harvest that year, but it was less than the normal amount. Farmers were hoping it would be contained and were not sure what to do. Now almost all the coffee plants we saw were dead. Coffee is the main source of income for the families of La Pita.

Without the coffee what are the impacts for the family, for the community, for the UCA, for the region ….? The women’s group has learned how to make home-made fertilizer with several goals: using them to renovate the coffee parcels as they prepare to plant them again; using them in their home gardens; and potentially selling them. The fertilizer is a mixture of minerals, forest fungus, forest soil, flour, and molasses. During our group’s visit, we joined the women’s group, along with Don Pedro and Juan Pablo, in making the fertilizer. It will be used in both the gardens and the coffee parcels. The farmers are very inspired by this process — both improving the soil with their own hands and saving a lot of money by making the fertilizers themselves. Don Pedro said, “When CAN first came to us, they told us we had everything in our own hands to move ahead. We’ve found out that we really do.”

Womens’ Gardens

When we were here in February 2013 with the AgroEco® Coffee Tour, there were no home gardens in La Pita. Farmers had their coffee parcels, many with fruit trees integrated to provide shade for the coffee and bananas, citrus, avocados, etc to eat. As part of CAN’s collaboration with the UCA and the families of La Pita there are now seven home gardens in La Pita plus a garden at the school. (This is part of a larger project with participants in other cooperatives in Nicaragua and coffee farmers in Mexico funded by Kuerig-Green Mountain Beverage Co.) As part of the project, Bismarck was selected as the youth leader to work on the developing of the gardens in La Pita. He receives training and participates in CAN’s annual international intecambio (exchange) among the youth leaders. The effort to establish the gardens comes at a critical time. Food from the garden is feeding families at a time when they have hardly any money to purchase essentials. See photos.

XV International Agroecology Shortcourse | End of Week One


Week One Wrap-Up

Throughout Central America there is a strong grassroots program called “Campesino a Campesino” where knowledge, based on farmer understanding, is shared. CAN has collaborated with Campesino a Campesino in several of our projects. We share similar philosophies of how to apply agroecology to achieve local food sovereignty.

We were visited by a team from Campesino a Campesino Nicaragua who shared their work with us. One of the leaders, Doña Carmen shared the work in her community of growing and saving local native corn seed. This is especially important today as a way to keep the high biodiversity of corn vibrant in communities throughout the Americas at a time when companies like Monsanto are attempting to get farmers such as these to use genetically modified corn which will lead to the loss of these local varieties. Hopefully these grassroot efforts to save the native varieties will flourish. It is organizations like Campesino a Campesino that will make this happen.

Robin, a student at UIMQROO and part of CAN’s International Youth Leadership Network, spoke to the course about his work with the women in the small Mayan town of Tabasco where they are developing alternative markets for locally grown food.

By the end of the week, course participants were divided into four groups. Each group will spend two days next week in a farming community talking with farm families and learning about the different efforts to develop sustainable practices that produce enough food to feed their families year round. Representatives from these four communities shared background information with course participants. CAN collaborates with farmers in two of these communities: (1) La Pita in San Ramón where AgroEco® Coffee comes from and (2) Cantagallo, a coffee growing cooperative that is part of CAN’s Las Segovias project. With this project, we are working together to develop ways to store grains and diversify farm production.

Poised for progress on drift

Well, it's about time. The invisible problem of pesticide drift is on the policy radar in ways it's never been before — with changes in the wings that could protect kids and communities in very real ways. But these changes won't happen unless we keep the pressure on.

From California to the Midwest to our nation's capital, drift is now a focus of public concern and policy conversation. And as the science linking pesticide exposure to children's health harms continues to stack up, pressure to protect kids from pesticide drift is growing stronger as well.

Pesticide residues: On the up & up

Last week, PAN UK released a report on pesticide residues in bread, analyzing government data over a 13-year time span. The report highlights extensive pesticide residues in some foods — including two-thirds of all bread products — and the ways in which food residue trends have shifted over time.

Pesticide residues have been in our food as long as we’ve been using pesticides. So it's not surprising (although still disturbing) that residues have significantly increased over the past decade. PAN UK’s analysis indicates that pesticide residues in bread alone have more than doubled from 28% in 2001 to 63% in 2013; and the number of samples testing positive for multiple residues have also more than doubled in the last seven years.

Hydrological connectivity as most probable key driver of chlorophyll and nutrients in oxbow lakes of the Bug River (Poland)

Publication date: March 2014
Source:Limnologica – Ecology and Management of Inland Waters, Volume 46
Author(s): Lech Kufel , Szymon Leśniczuk
Concentrations of chlorophyll, dissolved inorganic nitrogen and phosphorus, total phosphorus and suspended solids were analysed in 10 oxbow lakes of the Bug River in spring and summer. According to their connectivity with the river, all lakes were divided into 3 categories – lakes connected with the river channel but separated from the floodplain inputs, lakes connected with the river but receiving inputs from the floodplain and totally isolated lakes. Connected lakes showed significantly higher concentrations of available nutrients and chlorophyll but the relationship between the two variables was weak in the spring and non-existent in the summer. Suspended solids were also more abundant in connected than in isolated lakes. Analyses of the proportion of chlorophyll and particulate phosphorus in suspension led us to the conclusion that water movement in connected lakes inhibited sedimentation and kept algae in the water column. Isolated oxbow lakes devoid of wind-driven mixing were more susceptible to algal sedimentation which would explain the differences observed between the two lake categories.

Empty native and invasive bivalve shells as benthic habitat modifiers in a large river

Publication date: Available online 21 July 2014

Author(s): E. Bódis , B. Tóth , J. Szekeres , P. Borza , R. Sousa
Bivalves are remarkable ecosystem engineers and their long-lasting shells may provide important physical structures for benthic organisms. In the last decades the Danube River has experienced great changes in the bivalve fauna, i.e. several native species have been declining and several invasive species have been introduced. The invasive Corbicula fluminea and Sinanodonta woodiana are now widespread and produce large amounts of shells. In this study, we investigated empty shells of native ( Anodonta anatina , Unio tumidus ) and invasive ( C. fluminea , S. woodiana ) bivalves (including their mixtures) as benthic substrates and compared them to clay granules (control), which mimics the natural hard substrates in the Danube River (Hungary). Macroinvertebrate colonization was compared between i) empty shells and control substrate; ii) different bivalve species (native and invasive) and iii) three scenarios (before invasion, and short and long time after invasion) by using a mix of empty shells (native, native plus invasive, and invasive species). In comparison to control treatments the empty shells facilitated the presence of amphipods, caddis larvae and isopods, which contributed to a shift in the trophic structure by decreasing the proportion of gathering collectors while increasing the presence of shredders and predators. Several shell traits such as size, outer-shell surface roughness, hardness, thickness, 3D shape and chemical composition may be important attributes in the habitat modifying effects; however, this study could not disentangle which contribute most for the differences found. Given the capability of invasive C. fluminea and S. woodiana to accumulate large amounts of empty shells on several sites of the Danube, its habitat modifying effects can be particularly important, especially on the macroinvertebrate community structure. Moreover, these effects may increase in near future due to the predicted more frequent and severe extreme climatic conditions, which have been responsible for massive mortalities in both species.

A floodplain-scale lake classification based on characteristics of macroinvertebrate assemblages and corresponding environmental properties

Publication date: Available online 20 July 2014
Source:Limnologica – Ecology and Management of Inland Waters
Author(s): Baozhu Pan , Hongzhu Wang , Haijun Wang
Floodplain lakes have been experiencing great pressures by human activities, and ecological functions in different types of lakes show different degrees of degradation. For facilitating conservation and management of different types of floodplain lakes, it is necessary to classify the lakes into similar groups according to certain standards. In this study, on basis of consideration of macroinvertebrate assemblages and corresponding environmental properties, the Yangtze floodplain lakes were classified into three major types grouping five groups of lakes: 1) river-disconnected lakes (algal lakes, macrophytic-algal transition lakes, and macrophytic lakes), 2) semi-connected lakes (oxbow lakes), 3) river-connected lakes. The classification of floodplain lakes mainly reflects the gradients of trophic and hydrological connectivity. The key factors structuring macroinvertebrate assemblages in the Yangtze floodplain lakes were mainly hydrological (connectivity rating, water depth), trophic (total phosphorus, macrophytes biomass) and morphometric (development of lake shoreline). Among the floodplain lakes, ecological status of river-connected lakes, where biodiversity, biomass and production of macroinvertebrates reached maxima, has been confirmed to be the best. From the view of conservation and management of the entire floodplain lakes, it is suggested that protecting the remnants of river-connected lakes, controlling eutrophication and linking disconnected lakes freely with the mainstream are crucial.
