Responding in the Case of an Epidemic or Pandemic

Dawn Berkelaar


SARS-CoV-2, the virus that causes COVID-19, has been making its way around the world in the past weeks and months. The effects of this disease will almost certainly be felt by every community. Countries, where the infection is already well-established, have found it difficult to manage. Coping with a pandemic like this is particularly challenging in places with high population densities, lack of infrastructure, malnutrition, and incidence of other infections that leave people’s immune systems more vulnerable. Here are a few suggestions for ways to respond well in your community to the presence of a highly contagious disease.

Coup de projecteur sur deux membres d’ECHOcommunity : M. Tuntun et Thaung Si 2020-04-08

En me promenant dans la ferme avec M. Tuntun dans la campagne du Myanmar, je ne peux m’empêcher de sourire lorsqu’il me montre fièrement le biochar qu’il fabrique et utilise dans son mélange pour ses semis d’arbres fruitiers. Plutôt que de les brûler et de disséminer le carbone dans l’atmosphère, il transforme désormais ses déchets organiques issus de la ferme en une ressource précieuse qui peut être utilisée pour augmenter les récoltes.


Il y a environ un an, M. Tuntun a participé à un atelier sur la conservation des semences à Pyin Oo Lwin. Lors d’une séance de travaux pratiques, il y a appris à fabriquer du biochar. En rentrant chez lui, il a immédiatement essayé par lui-même et a rencontré beaucoup de succès. M. Tuntun a même créé une page Facebook sur laquelle il partage ses techniques agricoles avec d’autres agriculteurs birmans, expliquant des pratiques comme le biochar et beaucoup d’autres !

Integrating Black Soldier Flies on the Farm

Excerpt: The BSF or Black Soldier Fly (Hermetia illucens) brings great potential to any farming system through its ability to consume on-farm waste and produce a highly nutritious feed source. The larvae of the BSF can be grown using nearly any organic waste product, and can be used to up-cycle waste materials into a valuable protein source. BSF have the ability to break down waste resources that cannot be directly fed to humans or livestock, or even worms in a vermicomposting system, thereby making these systems valuable in tightening the nutrient cycle on any farm. In addition to the feed that the larvae becomes, the secondary advantage is their ability to rapidly break down food waste to produce a valuable by-product that can be used as an organic soil amendment.

Méthodes à faible teneur en oxygène pour traiter les insectes dans des graines

Tim Motis


Les graines sont généralement stockées pendant un certain temps avant d'être semées ou consommées. Tout insecte présent dans cette graine, s'il n'est pas traité, peut se multiplier rapidement et causer des dégâts importants

De nombreux ravageurs d’entrepôts proviennent du champ. Les graines peuvent sembler exemptes d'insectes au moment de la récolte, mais des œufs et des larves provenant du champ peuvent encore être présents. Les insectes peuvent également s’introduire lorsque les graines sont placées dans des récipients de graines ou des bacs à grains précédemment infestés. Les dégâts causés par les insectes réduisent la germination et la qualité des graines et sont une cause majeure de perte de graines après récolte. La plupart des pertes de graines post-récolte liées aux insectes sont causées par diverses espèces de scarabées (de l’ordre des Coléoptères) et des larves de mites et de papillons (de l’ordre des lépidoptères). Cet article met l’accent sur les charançons, qui sont un type de scarabée spécifique.

From the ECHO Research Blog: Vacuum sealing for seed preservation 2020-01-17

Postharvest seed loss due to insect damage is problematic for farmers as well as seed banks. One approach to control insects in a container of seeds is to lower oxygen levels using vacuum drawn with modified bicycle pumps, brake bleeder pumps, or other devices (see ECHO TN 93).

Air contains 21% oxygen by volume, meaning 100 liters of air is comprised of 21 liters of oxygen. Research has shown that insect mortality occurs when 5% (or less) of a container’s volume oxygen is occupied by oxygen (Njoroge et al., 2019). How do you know if your vacuum is strong enough to achieve such low levels of oxygen?
