What’s a Pulse?

Legumes are the 3rd largest family of flowering plants

• Second only to grasses in agricultural importance

• Keystone family for nutrition

Pulses are legumes of which we eat the seed

Why legumes?

Of particular importance in food

insecure regions of the world

A key source of humankind’s protein nitrogen

• High Protein content of seed

• Enrich soil in vital nitrogen

In non-legume systems, nitrogen derives primarily from industrial processes that depend on fossil fuels.

Nitrogen drives agricultural costs, is among the world’s most significant pollutants and major contributor to greenhouse gases.

The predominance of legumes in developing world diets, makes them key vehicles for delivery of both micro and macro-nutrients

Iron, zinc, fiber, oils and fats, caloric intake …

Feeding a growing world

• A large and growing population in which malnutrition is the

most widespread human malady.

• Large disparities in production, capacities, income.

• Urgent need to increase the efficiency of agricultural

systems, while reducing environmental impact.

• Longstanding challenges to agriculture – disease,

drought, variable inputs, etc.

• Increasing planetary warming, with more extreme and

less predictable weather.

• Need for increased investment in research and

development.

Since the Green Revolution, legumes received significant underinvestment.

The best land and the major financial investments have been in grasses: rice, wheat and maize, for examples.

In the developed world, animal protein has replaced legumes, despite significant upsides of legumes for health and sustainability.

Agriculture under stress

70% of the freshwater used by humans is for agricultural purposes, often exceeding local regeneration rates. Irrigation alone is not sustainable.

“Meeting humanity’s increasing demand for freshwater and protecting ecosystems at the same time will be one of the most difficult and important challenges of this century”

Mekonnen and Hoekstra Sci. Adv. 12 Feb 2016

66% of the human population (4.0 billion people) lives under severe water scarcity (WS > 2.0) at least 1 month of the year. Of these, half a billion people face severe water scarcity all year round.

Year-in, year-out, water availability is the major factor limiting agricultural yields

The changing climate will impact developing countries most

• Countries close to the equator will suffer declines in productivity.

– heavily depend on agriculture

– already warm environment

– lack of infrastructure to adapt to changes

– lack of capital to invest in innovation adaptation

• Commodity prices will increase due to the reduction in production.

• Higher commodity prices would increase farm revenue, but hurt poor

farmers who consume more than they produce.

The problem of climate is more than just drought

• Drought

• Heat

• Cold

• Pests and Disease

• Nitrogen fixation

Terminal drought is the most consistent threat to chickpea production

… in Ethiopia, farmers plant AFTER the summer rains conclude, which exposes the crop to drought. WHY?

•Nitrogen fertilizers are not

an option.

•Degraded soils compound

plant nutrition.

Most of the world’s poor live in the semi-arid

tropics …

… where drought and heat

are most severe

Drought and heat suppress

legumes’ potential for N-

fixation

Global Context

• Severe hunger and poverty affects nearly 1 billion people

around the world.

• By 2050, it’s estimated that the earth’s population will reach 9

billion. Global food production will need to increase

significantly to 100 percent to feed these people.

• Two billion people in the developing world are malnourished

-- the world’s most serious health problem.

The power of investing in agriculture is clear: Agricultural

development is two to four times more effective at reducing

hunger and poverty than any other sector.

How do we address these challenges?

• Partnerships: governments, foundations, international

organizations, scientists, engineers, farmers, etc.

• Sustained investment with a variety of time horizons

• Recognize the importance of scale: “local problems and

priorities are not necessarily global problems and priorities”

• Embrace diverse scenariosInfrastructure (Roads, seed systems, etc)

Terminal drought: year in, year out, most serious constraint.

Terminal drought

Chickpea production is limited byDrought, heat, disease and low genetic diversity

Terminal drought: year in, year out, most serious constraint.

Drought and heat:

Predispose the crop to disease.

Reduce rates of nitrogen fixation.

Requires a multi-faceted approach.

~95% of variation in the crop was lost during domestication and modern breeding

Drought tolerance

Heat tolerance

Nitrogen fixation

Plant architecture for mechanical harvesting

Seed nutrient density

Fusarium resistance

Pod borer resistance

Improve farmer livelihoods and increase agricultural productivity

For crop improvement, the way forward is genetics

Breeding: novel alleles typically come from domesticated germplasm, … landraces and wild relatives are largely ignored.

Biotechnology: accesses alleles from a broader set of organisms (transgenics), and to modify endogenous genetic components (cisgenics).

Accessing, characterizing and

utilizing genetic variation

Breeding needs variation

We explored chickpea’s center of origin over 56 days

in 2013 and 100 days in 2014/15 at ~50 sites
