Feet of clay

That’s another one to tick off the life list. Above you see Zhu Youyong, who describes himself as a farmer. He happens also to be Distinguished Professor Zhu, President of Yunnan Agricultural College and a hero of mine.

Zhu’s name is associated with a method of growing rice that delivers higher, more stable yields with lower inputs of fungicides and a more stable harvest from year to year. Not bad for an amazingly simple idea. The problem is that traditional landraces of sticky rice, which farmers like to grow and to eat, are susceptible to fungal disease. They also have a nasty tendency to fall over, or lodge, especially when they are carrying a bountiful load of seed. Modern hybrids are disease resistant, and high-yielding, but the taste is not much to write home about. Yields are high, but prices are low. To grow the tasty traditional landraces, farmers need to be able to afford fungicides and they need to be able to overcome their tendency to lodge.

Coffee in Rwanda

A recent paper from the Mercatus Center at George Mason University of looks at the specialty coffee industry in Rwanda. Among its conclusions:

  • the specialty coffee industry in Rwanda aids in local poverty alleviation and job creation;
  • the specialty coffee industry provides opportunities for developing business and management skills;
  • the actions of specific coffee entrepreneurs have affected the lives of ordinary Rwandans; and
  • entrepreneurial activities within the Rwandan specialty coffee industry provide Rwandans with opportunities to interact in ways that may promote post-conflict reconciliation.

It is a long read, but with a good cup of Joe by your side the time will fly by.

Promotion of new crops and its effects

Following on from yesterday’s post, which looked at the UNEP-WCMC report on the ecosystem services provided by biodiversity, including agricultural biodiversity, I wanted today to signal the publication by the International Centre for Underutilised Crops (ICUC) of a new position paper which is somewhat related, and of which I am a one of the authors. ((Dawson, I.K., Guarino, L. and Jaenicke, H. (2007) Underutilised Plant Species: Impacts of Promotion on Biodiversity. Position Paper No. 2. International Centre for Underutilised Crops, Colombo, Sri Lanka.)) This looks at the impact of promoting underutilised plant species (UPS) on overall levels of biodiversity in farming systems.

ICUC’s position on biodiversity is that its promotion should not be viewed as an “end in itself.” Rather, diversity needs to be “conserved through use,” or the livelihood opportunities it presents and the other services that it provides to the poor, both primary producers and local product processors, now and for the future. The significant nutritional and other health benefits received by consumers further afield in, e.g., urban areas and in other countries, through being able to access a more diverse range of foods, medicines and other products, should, however, also not be neglected.

Clearly, there are significant benefits that can accrue to poor families and communities, as well as others, through the promotion of one or more UPS — better nutrition, health, income etc. However, such promotion can result in the erosion of diversity in other crops, and in the agricultural landscape as a whole. If that happens, any benefits which UPS promotion delivers in the short term could be outweighed by long-term negative effects on the provision of the sorts of ecosystem services the WCMC paper discussed. ((We also discuss in our paper the complexity of the linkages between diversity, productivity and stability.))

In the ICUC paper, we look at the possible methods that can be used to promote UPS and suggest a number of conditions that should be met if such interventions are not to have undesired effects on biodiversity and the services it provides:

  • Possible consequences of promotion for agricultural and natural biodiversity should be described in advance, in order to assess potential livelihood and conservation risks.
  • Specific incentives that support diversification should be included when promotion of a UPS carries significant risks for biodiversity.
  • Particular actions that are known to support biodiversity should be used during promotion, e.g. improving germplasm access and supporting “intelligent markets” for products.
  • The consequences of promotion activities for biodiversity, and the linked impacts on livelihoods, should be monitored.

“Intelligent markets” are ones that improve both incomes and environmental management. Developing such markets “will involve educating producers and microprocessors in how to diversify their activities, encouraging value chain development, and supporting DO [denomination of origin] and related initiatives.” I particularly wanted to highlight this point because, coincidentally, FAO has just published a report on “Approaches to linking producers to markets” which looks at how best to help farmers organize themselves to supply identified markets. ((Andrew W. Shepherd (2007) Approaches to linking producers to markets: A review of experiences to date. Agricultural Management, Marketing and Finance Occasional Paper 13. FAO, Rome.))

We’ve had a few examples of this on the blog lately, haven’t we? They have ranged from the Ojibwa and their wild rice to the “under the sun” cheeses of Italy just in the past few days. Is it a zeitgeist thing?

Ethiopia goes for decaf

Reuters reports that Ethiopian coffee farmers will soon be able to grow a variety which is naturally low in caffeine. Details are sketchy. The whole thing seems to be based on the following statement by Mr Abera Deressa, State Minister of Agriculture and Rural Development, at an unnamed coffee research conference:

“Coffee research centres are in the process of planting seedlings of natural coffee with low caffeine varieties, to enable Ethiopia to supply the world market within the shortest possible time.”

The article mentions the 2004 controversy between the Ethiopian government and Brazilian researcher Paulo Mazzafera, who

declared he had discovered a variety of naturally decaffeinated coffee from 6,000 specimens collected in Ethiopia in the 1980s. The find sparked a dispute with Ethiopian authorities who accused him of taking the bushes without permission.

However, it is not clear whether the low-caffeine variety now being planted in research centres has anything to do with the one Mazzafera identified.

Decaffeinated coffee accounts for 10 percent of total coffee sales in the world, a multibillion-dollar industry. Natural decaf brews could dominate over the current chemically caffeine-reduced options in today’s health-conscious market.

The story has been picked up all over the place. It should run and run. Hopefully we’ll get some more details soon.
