African agriculture & climate change

A new report recently published by IFPRI highlights the point that while most African farmers perceive that there will be significant changes in rainfall and temperature due to climate change,  they have done little to adapt their farming practices to these changes. The research carried out for this report was undertaken in Ethiopia and South African and 1800 households were interviewed.

The report states some of the reasons as to why adaptation has been slow: “South African farmers identified lack of access to credit as the single biggest constraint to adapting to climate change, followed by lack of water, information, and market access, and insecure property rights. In Ethiopia, farmers identified lack of land as the major obstacle, followed closely by lack of information and credit. They also noted that lack of labor, inputs, and water, as well as poor soils, prevented them from adapting.”

The research shows that farmers who did adapt where the ones who irrigated more, harvested water, planted different crops, changed planting dates, and practiced soil conservation measures, including the planting of trees.  These farmers were more likely to adapt if they had access to credit and extension, owned private property, and had more farming experience or mixed crop and livestock farms.  Read more

Starting Monday 17 November, the Agrobiodiversity and Climate Change Project, supported by Bioversity International and the Christensen Fund, is hosting an online discussion to identify gaps in current knowledge about the effects of climate change on local communities and their use of agricultural biodiversity.

Narrow genetic base of chickens

An article in the New Scientist magazine reports on a study showing that modern commercial chicken breeds have lost over half  the genetic diversity of their ancestral lines (Proceedings of the National Academy of Sciences, DOI: 10.1073/pnas.0806569105). This is due to the small number of breeds used in crosses.

A more extensive write-up in Scientific American highlights the consequence of this narrowing of the genetic base of our food animals in terms of vulnerability to diseases and other pressures.

There is a need for some serious ‘base-broadening’ within the poultry breeding industry, going back to wild relatives to regain some of the diversity that has been lost.

Rainforest fungus produces bio-diesel

A story on ITN demonstrates again the value of preserving rainforest, indeed all biodiversity.

The story reports on the discovery in a Patagonian rainforest of a fungus that produces a substance similar to diesel. The fungus, Gliocladium roseum, converts cellulose directly to bio-diesel.

The potential application in the biofuel industry is obviously huge. It’s a shame that the article does not pick up on the implications for biodiversity conservation. It also ignores the IPR issues — it mentions only the US scientist who lead the investigation into the fungus; nothing about the potential benefits to the country where the fungus was discovered or anything about indigenous knowledge about the fungus.

Biodiversity & Agriculture

“Biodiversity and Agricultures : Today’s Challenges, Tomorrow’s Research for More Sustainable Farming” is the theme for the conference that will be held this week in Montpellier, France.  It will be held over two days (4th-5th November) and the main topics up for discussion include:

  • Ecosystems and agriculture
  • Agriculture, biodiversity and society: the footprint and the drivers; North/South perspectives
  • Agriculture and biodiversity in complex landscapes: pointers towards new policies
  • The way forward for science: what we need to know and how to apply knowledge to improve the situation.

Click here to view the programme and the speakers. This conference is also viewable by live streaming.  If you’re keen to look at and participate in some of the discussions currently on, you can visit the forum page and register.

Seaweed: a new source of energy?

A new report has been recently published that outlines the possibility of farming seaweed and marine algae as a future green energy source. The report was commissioned by The Crown Estate and conducted by researchers at The Scottish Association for Marine Science.

The report details the potential of using seaweed to produce biomass for heating homes or running transport, while avoiding the problems associated with biofuels, such as the use of valuable agricultural land.

Other advantages to be had from generating energy from marine biomass included in the report are:

  • it avoids the problem of switching agricultural land from food to fuel production
  • unlike terrestrial biomass, it is not be limited by freshwater supplies
  • seaweed has high conversion efficiencies and rapid conversion rates
  • the residues are suitable for use as nutrient supplements for agriculture
  • seaweed farms may also increase local biodiversity, absorbing some of the excess nutrients in run off from agricultural land, which can cause problems such as algal blooms.

The press release is available here and if you are interested in obtaining the full report the website requests that you register.

Potatoes: a way out of the food crisis?

Potatoes are increasingly being seen as a possible solution for the recent food crisis that is hitting many developing countries.  As grain prices continue to rise,  scientists and governments are encouraging the cultivation of potato crops to steady the shaky food supply problem.

In an article from the New York Times, it states: “Production in China rose 50 percent from 2005 to 2007, and the government has called potatoes “a way out of poverty.” In Peru, where potatoes are traditionally part of the highland diet, President Alan García has led a campaign to promote potato eating in cities. Schools, prisons and army canteens are serving papapan, bread made with potatoes, helping to increase potato consumption by 20 percent increase this year”

Bookmobile with a difference

For many of us having access to information is a given;  we take it for granted, and we often get annoyed if our internet connection is slow, or our request for information hasn’t been responded to in the last half hour.

This week, at Bioversity Library, we have a liking for photos and images.  So we thought we’d share the following slideshow from the New York Times.

Photos on sustainability

We read and hear so much in the news and scientific journals about the effects of climate change, however  we don’t seem to see many images that show the effects of the changing climate except for the usual images of icebergs melting.  This is where the Prix Pictet plays a role.

Never heard of the Prix Pictet? Nor had we until today, but after visiting their website and viewing the amazing photos,  we felt that this was a resource to be shared with our readers. The Prix Pictet is a major new global prize in photography that focuses on sustainability. It will have a yearly theme and the one for 2008 is: water.    Read more about this prize here.

The jury has already decided on the 2008 shortlist and the photos can be viewed here.

Click on the artist’s name to view a collection of their photos.  Enjoy!

Terra Madre 2008 meeting

The Terra Madre network will hold its third international biennial meeting in Torino later this week, from October 23 to the 27th.  It will bring together people who are passionate about their beliefs and goal of working towards increasing small-scale, traditional, and sustainable food production.

This unique network is growing day by day and is made up of three main groups:  Food communities , Cooks and Universities - all who have the same objective: to act to preserve, encourage, and support sustainable food production methods.
