Some questions from day 2 in Amman

Got to go out to dinner, so not much time to blog, but I thought I’d tease you with some of the more interesting questions that were posed by speakers during this second day of the Amman conference on food security in the drylands under climate change. I’ll post (some of) the answers later.

Calvin Qualset: What’s so new about climate change for breeders?
Jose Cubero: Why are there no commercial faba bean hybrids?
Raj Paroda: Is aerobic rice the answer to decreasing methane emissions?
Theib Oweis: Shouldn’t we measure productivity on the basis of unit of water consumed rather than of land used?
Ken Street: Can’t we think of a better way of identifying germplasm for evaluation than core collections?
Salvatore Ceccarelli: Why, in this year of biodiversity, are we still wedded to the idea of varietal uniformity?

Day 1 at the Amman drylands conference draws to a close

The afternoon plenary (see here for the morning) consisted of talks by Drs Adel El Beltagy (GFAR) and Mark Rosegrant (IFPRI). Again, here’s what struck me particularly out of the many interesting things they said.

  • Svalbard Global Seed Vault provides a Noah’s Ark for the world’s crop germplasm collections, which we’ll need for both adaptation and mitigation.
  • Transboundary livestock diseases will increase, but there are opportunities for mitigation through better livestock genetics, feeding and management.
  • Agro-ecosystems will be disrupted by climate change, and we don’t have the methods to predict what the new ones will look like, or whether they will be able to function.
  • Nanotech can be used not just in a bunch of molecular genetics applications, but also for smarter delivery or inputs.
  • It’s not just climate change: there’s a host of both demand and supply drivers behind the bad stuff that’s happening to food security.
  • Biophysical models predict following changes in global production: irrigated rice -27% (but N. China a winner); rainfed rice -13%; irrigated maize -13% (it will reach the Canadian border!); irrigated maize -16% (N. China a winner again); irrigated wheat -42% (disaster in India); rainfed wheat -28% (India again in trouble).
  • Add economic models to that and you have a predicted doubling of prices by 2050, a 22% drop in calorie consumption in developing countries and a 21% increase in child malnutrition in developing countries.
  • To fix this, via expansion of irrigation, better roads and more research, will cost an extra $7 billion a year, on top of the current $12 billion being spent on those things now.
  • Increased productivity is fundamental, sure, but let’s not forget rural infrastructure.
  • There may well be a potential $150 billion a year up for grabs for agriculture if a decent C trading system develops. But will need low-cost monitoring and verification, and innovative payment schemes.
  • We’re going to need better local scenarios, but the danger of that is that you begin to not see the wood for the trees (too much weather, not enough climate).
  • Nibbles: Orissa, Salatin, Economic impact, Olives, Food security, Lettuce, Chayote

    Stop deforestation with pretty videos

    With regard to the false choice between rainforests and beef, here’s a nice little bit of propaganda.

    I expect it plays better on Central Park West and Holland Park than in Brazil or Indonesia, and a single tree downed by a chainsaw is no match for two Caterpillar tractors chugging through the rainforest linked by a massive chain. My question is this: what does the video, pretty and moving though it is, want me to do? All may be revealed on Earth Day 2010, apparently.
