Memfasilitasi Bursa Benih - 20 Maret 2013

Since 2011, ECHO Asia has developed and facilitated seed exchange events during meetings with local partners. Through conversations with farmers and NGO staff, we have gained better insight about locally-important plant varieties, seed saving practices, attitudes towards saving seeds, and sustainable farming. The most exciting part of these events is hearing success stories! At our first agriculture workshop in Myanmar during November 2012, we were excited when one organization from southern Shan State brought over 75 cuttings of chaya to share with delegates, after having successfully introduced it as a food and forage plant on their small farm resource centre. All of their stock came from a single cutting received only one year earlier during ECHO Asia’s biennial Tropical Agriculture conference in Chiang Mai!

In this article, we share our method for implementing seed exchanges that are carried out in the local language and attended by local farmers and development workers. The materials required for a seed exchange are basic, but the actual process of exchanging and capturing information requires prior preparation and an adjustment based on the culture and realities in the particular country.

During the 2012 ECHO Agriculture Workshop in Yangon, 63 attendees representing at least 25 agriculture and community development organizations from across Myanmar were polled about their observations and opinions related to climate change. The vast majority of the respondents indicated that they were not only aware of climate change, but that they had also noticed change in the local climate or weather patterns. Additionally, 86 percent expressed that they understood that climate change is caused by human activity.

Belief in climate change fluctuates and varies worldwide, with some populations more convinced of change than others. A September 2012 Yale University poll determined that seven in ten Americans (70 percent) believe global warming is happening, while relatively few – only 12 percent – believe it is not. But while overall belief in climate change may be increasing around the world, understanding the roots of its cause appears much more limited. In addition, necessary strategies for adapting to climate change as well as determining approaches to address (or mitigate) its causes are still preliminary.

Meanwhile, climate change is already causing deaths and damaging the global economy. A 2012 study carried out by the DARA Group and the Climate Vulnerable Forum concluded that climate change was already contributing to the deaths of nearly 400,000 people a year and costing the world more than $1.2 trillion US, wiping 1.6 percent annually from the global economy. The impacts were being felt most keenly in developing countries, where damage to agricultural production from extreme weather linked to climate change has been contributing to deaths from malnutrition, poverty and their associated diseases (The Guardian, September 26, 2012). The impacts are expected to worsen over the next two decades (Reuters, September 26, 2012)

Penilaian Kualitas Tanah - 01 Oktober 2012

Soil quality, also known as soil health, is the capacity of the soil to function – how well it fills the roles we need it to, whether in a natural or managed ecosystem. There are a variety of measures used to gauge soil health and although we can use these characteristics as indicators of soil quality, ultimately soil quality is judged by how well it fulfills its functions. Many indicators require complicated and technical lab testing, but many can be carried out with locally available materials as well. Learning about your soil can be a good way to identify appropriate crops for your setting or look for potential problems.

Soil is a complex matrix of inorganic (mineral) particles, non-living organic (comprised of carbon) particles, air, water, and living biota. Soil functions generally fall into five categories: sustaining biological diversity and productivity, regulating water and solute flow, filtering and degrading organic and inorganic matter, cycling nutrients, such as nitrogen and carbon, and providing stability and support. Soils are evaluated in terms of both dynamic and inherent soil qualities; those that vary and do not vary based on use (respectively). 

Understanding the many organic and inorganic parts that go into making up the soil can help us develop healthy, productive soil that fills our needs. At the ECHO Asia Seed Bank, we use a number of different production plots with very different site histories, and we were interested in comparing the relative strengths and weaknesses of each plot – both what crops these sites may be best suited for and how to improve the soils present in them.

Mendeskonsistensi Produksi dan Pemasaran Kedelai: Pengalaman kami di Laos - 01 Oktober 2012

This article is from ECHO Asia Note #15

Editor: Between 1997 and 2009, Kirby Rogers worked as part of a team to establish an agriculture-based business called Natural Products (NPI) in Bokeo, Laos. Much of this effort involved promoting soybean as a local cash crop as well as developing related milling and marketing channels. During the 2011 ECHO Asia Agriculture and Community Development Conference, Kirby provided a plenary presentation titled, “Business-Based Development and Completing Broken Economic Chains in Developing Countries.” Information from that presentation is shared here. 

In this article, I do not want to give a “wiki history” of the soybean plant, nor a science-based explanation of its properties, nor an economic review of soybean markets. Instead, I will share a more personal look at this plant and how it has directly impacted the lives of many Lao people.

Since this story concerns agricultural development as well, I want to introduce some of the strategies we learned while introducing soybean production to remote locations within Laos. However, I will start at the ending. There are now scores of villages planting soybeans in several locations across northern Laos, producing thousands of tons of soy per year. 

Vacuum Sealing vs. Refrigeration: Mana cara yang paling efektif untuk menyimpan bibit? - 01 Juli 2012

Introduction

Storing seeds in the tropics can often be difficult; with high temperatures and humid conditions, seeds lose their ability to germinate quickly. Many techniques for seed storage exist, from the high-tech standards of gene banks to simple methods used by villagers for saving their own seeds. All have their strengths and weaknesses, but when balancing costs and resources, which methods are really the most effective? To find appropriate low-input storage methods for storing seeds, the ECHO Asia Seed Bank recently completed a study on tropical seed storage under the resource-constrained settings this seed bank encounters.

The three key factors that determine the rate of seed deterioration in storage are: oxygen pressure (amount of oxygen with the seeds in storage), seed moisture content, and temperature (Roberts, 1973). An increase in any of these factors will lower the storage life of the seeds, and as a general rule any increase of 1% moisture content or 10o F (5.6o C ) in storage will halve the storage life of the seeds (Bewley and Black, 1985). Each factor contributes to seed decay in specific ways, and minimizing these conditions is critical to effective seed storage.

The goal of this research was to evaluate two seed storage options: vacuum sealing and refrigeration. Vacuum sealing is a relatively low-cost method that requires few inputs after an initial investment. Sealing helps conserve seed quality by minimizing oxygen presence and exposure to ambient humidity, thereby keeping seed moisture content low. Refrigeration minimizes temperature, but can also be expensive to maintain in tropical conditions. We used five tropical seed varieties to compare the effects of these storage methods over the course of one year; our goal was to use the outcomes of this study to help prescribe storage conditions for this seed bank and others like it around the world.

Pompa Genetika Tanaman: Kemungkinan Tugas untuk LSM - 01 Juli 2012

Editor: Dr. Dick Tinsley is an Emeritus Professor with Colorado State University. With decades of experience as an advisor to smallholder agriculture development projects, he was worked in numerous locations across Asia and Africa. In this article, Dr. Tinsley draws upon his experience regarding locations where governmental certified crop seed development and distribution programs remain insufficient to meet agricultural demands and suggests a concept that he refers to as the "Crop Genetic Pump" to show how the non-governmental sector might facilitate access to seeds of improved varieties.

Introduction

In the overall economic environment common to most developing countries, the government usually attempts to provide civil services, including agricultural support services, similar to those provided by developed countries. This normally substantially exceeds the limited revenue funds and results in many programs being more on paper than in reality. When possible, important services such as these are deferred to Non-Government Organizations (NGOs). Included among these are crop variety development, seed multiplication and distribution efforts. NGOs working with smallholder communities have an excellent opportunity to informally provide a valuable and durable service by obtaining small quantities of advanced breeding lines for the important crops produced in their host communities. They can then multiply them within the community for sale and distribution to the smallholder farmers at or near market seed prices instead of at certified seed prices, which typically cost twice as much.

Tiga Kelebihan Jali: Padian Asli Asia Satu Lagi - 01 April 2012

Pengenalan
Di banyak bagian daerah tropis Asia, khususnya di ladang tadah hujan, terjadi penambahan luar biasa penanaman jagung dalam ukuran luas. Penambahan produksi jagung komersial didorong oleh pertumbuhan permintaan pakan ternak, dan sedang mengganti banyak tanaman
traditional termasuk bahan baku beras dataran tinggi.

Sebelum ledakan jagung di Asia pada saat ini, dan bahkan ribuan tahun sebelum pedagang Eropa membawa tanaman ini ke Timur Jauh, satu tanaman yang disebut jali (Coix lacryma-jobi) ditanam sepanjang Selatan, Tenggara dan Asia Timur. Jali tetap ditanam sebagai sereal untuk konsumsi manusia, dan juga sebagai pakan ternak (keduanya bijian dan hijauan).

Produksi Sayuran Melalui Musim Hujan - 01 April 2012

The cool, dry season offers the best window for vegetable production in the tropics, assuming an adequate water supply. Pest and disease pressures are relatively low and temperatures are moderate. By contrast, the rainy season brings a combination of high temperatures and humidity that encourages the return of voracious snails and other pests. This means that many desirable vegetables, such as lettuce and tomatoes, are difficult to produce under rainy season conditions without significant inputs such as plastic row covers and pesticides.

Terutama pada saat anda menemukan satu varietas lokal dari tanaman yang menjanjikan tumbuh di wilayah anda, bagaimana anda bisa memampukan petani lain untuk mencoba varietas ini? Jika seorang petani memberikan engkau 30 jenis varietas unggul, bagaimana anda memikirkan untuk mendistribusikan? Bagaimana aliran bibit berlangsung di masyarakat dan diantara beberapa komunitas dimana anda bekerja?

Di artikel ini, kami membagi pengalaman ECHO Asia membantu menyelenggarakan 4 pekan bibit. Kami juga mencatat beberapa komponen penting dari satu pekan bibit, sehingga anda bisa belajar dari pengalaman kami jika organisasi anda tertarik menjadi penyelenggara.

Strengthening Informal Indigenous Seed Systems in Southeast Asia

This article is from ECHO Asia Note #12

In 2010 the ECHO Asia Impact C enter, along with lead partner, Pennsylvania State University, and Maejo University, was awarded a CRSP Horticulture Exploratory Project grant with major support from USAID. Entitled, "Strengthening Indigenous Informal Seed Saving Systems in Southeast Asia," the project enabled the three institutions to carry out a year-long exploratory study of household seed saving practices and related challenges in hilltribe communities along the Thai-Myanmar border as well as Khmer farming communities in southwest Cambodia.
