Green Manure / Cover Crop Resources 2019-06-13

Green manure cover crops (gmcc) are rapidly growing crops that cover and protect the soil. There are a lot of great resources including and interactive selection tool for GMCCs on ECHOcommunity.org including an ECHO Technical Note on “Green Manure Cover Crops” and the GMCC Selection Tool.

Restoring The Soil: Second Edition Now Available 2019-05-23

Green manure/cover crops (gm/ccs) enrich the soil while providing numerous other benefits such as weed suppression and food for human and/or animal consumption. Understanding their functions, selecting gm/ccs for specific growing conditions, and knowing how to integrate them on small-scale farmsteads can be a daunting process. Roland Bunch's second edition of "Restoring the Soil" helps practitioners and farmers learn about gm/ccs and choose context-appropriate gm/cc systems already in use by farmers.

Part 1 of the book explains benefits and limitations of gm/ccs, common misconceptions, and mistakes made in using them. It discusses how gm/ccs relate to soil improvement, tropical agriculture, and climate-smart practices that sequester carbon and mitigate against drought.

Part 2 guides the reader through a unique, incremental decision-making process for selecting which of 117 gm/cc systems have the most potential for success in their setting.

Learning about and from Local Seed Systems

Dawn Berkelaar

Excerpt:

Access to viable seed is critical for successful farming. This is one reason our seed banks in Florida (USA), Thailand, and East Africa offer trial packets of seed to our network members. We have written about how to hold a seed fair, to enable people within a community to share and acquire seeds directly from each other. But what do we know about how seed normally flows throughout a small farming community?

Guest Post by ECHOcommunity member: Muneezay Jaffery

This is part 3 of a series describing how one network organization is progressing with development of training facilities and curriculum.

The team are now doing village outreach work with banners and hand-outs at the ready.  There are challenges at hand- are people interested? What sets us apart? How can we ensure regular attendance?

Parasitic Plants in African Agriculture - ECHO Technical Note #94 2019-03-27

ECHO's newest Technical Note, by Lytton John Musselman, provides an overview of parasitic plants of agricultural significance in Africa. Parasitic weeds cause drought stress and stunted crops. Important grains such as sorghum, maize, and cowpea are affected. Damage to these and other crops is worsened by low soil fertility and drought stress, conditions that are faced by many African smallholders. Parasitic weeds can lead to severe yield losses, making them an important constraint to food security in many areas.

Agriculture Training and Youth Motivation in NW Cambodia - Planning and Building 2019-03-12

Guest Post by ECHOcommunity member: Muneezay Jaffery

This is part 2 of a series describing how one network organization is progressing with development of training facilities and curriculum.

Whilst working on the planning and build, our aim was to “repackage” what horticulture means within a rural community. One main strategy was to include low cost, affordable tech within the space. Our bottom line for decision-making was “is it replicable? How much will it cost? What are the benefits?”

The Green Shoots Foundation Agritech Centre is situated on a 0.5 Ha piece of land which was, until last year, an over-grown site of shrubs and trees. In July, 2017 the government provided the land on a concession based on 6 years of running horticulture projects focusing on natural farming techniques within educational schools.

Understanding Agriculture-Nutrition Linkages

By: Cecilia Gonzalez

Excerpt:

In recent years, much attention has been given to the connections between agriculture and nutrition in the development sector as a whole. These connections may seem obvious: we get nourishment from the food we eat, and we eat food produced by agriculture. However, the claim that agriculture interventions (e.g. home gardens) can improve nutrition has come under scrutiny, because of the lack of evidence to substantiate it (Masset et al. 2012; Girard et al. 2012). 

At the same time, recent efforts have helped us to better understand these linkages and to begin to close the evidence gaps. Agriculture plays an indispensable role in development, and though it doesn’t automatically improve nutrition, its potential to do so is undeniable. The recent efforts have provided important frameworks for program design and for implementing agriculture interventions that aim to improve the nutrition of vulnerable populations.  These frameworks for “nutrition-sensitive agriculture” interventions help us make sense of complex problems and identify pathways to solutions.

Vacuum-Sealing Options for Storing Seeds 2019-01-15

Quality seed is crucial for initiatives aimed at preserving or increasing crop diversity. Whether seeds are purchased or grown out and collected in the field, they typically need to be stored until conditions are right for planting. How those seeds are stored affects how many will germinate and grow when planted.

Seed survival during storage depends on seed moisture content, air temperature, and oxygen levels. Increases in these factors causes seeds to metabolize their food reserves more quickly, shortening storage life. Seed moisture content is influenced by the humidity of the air in the storage space or container. Hot, humid conditions lead to rotting of seeds. For these reasons, being able to improve seed storage conditions is highly beneficial to farmers and development practitioners, particularly those working in the humid tropics.

Vacuum sealing seeds is an effective way to extend their viability, for two main reasons. First, maintaining seeds under a vacuum keeps humidity out of the storage container, which is very important in areas where humidity is high during at least part of the year (e.g. during rainy season).

This new ECHO Technical Note presents ways to remove air from seed containers, for the purpose of extending the viability of stored seeds. The technologies presented here are most relevant to community-level seed banks or development practitioners looking for options for storing small volumes of high-value seed for planting. They would not be practical for storing large quantities of grain for human or animal consumption. With the exception of commercial vacuum sealers, the technologies presented are inexpensive, and many can be constructed with local materials.

Gardening on Rooftops & Other Above-Ground Locations 2019-01-03

New book by ECHO founding CEO Dr. Martin Price

A major cause of hunger and malnutrition is a lack of income sufficient to purchase food. Anyone with enough income will be able to obtain food, except perhaps after major disasters or in a war zone. For many, an option of last resort is to find a piece of land somewhere and try to grow enough to at least keep the family alive.  But how does someone in an urban area with nonexistent financial resources get land to cultivate?

This book highlights techniques for most rooftop gardens. These techniques can be done at a fraction of the expense that is normally considered necessary andy do not require specially engineered buildings to make sure that the roof can handle the weight of the soil.
