CGIAR case study: research

highlights from Latin America

25 May 2016LED BY

A collaboration of

• Around 200+ research-for-development stakeholders

& partners

What is the

?

BananaPlantain

Cassava Potato Sweetpotato Yam Other R&T

300 million small holder farmers and

processors depend on RTB crops for food

security, nutrition, income and employment

What are our crops?

What are our systems?

RTB crops share

• Genetic complexity,

similar breeding

challenges

• Vegetative propagation,

similar seed systems

• Perishability, bulkiness

and post harvest/value

chain options

Why Roots, Tubers andBananas?

Latin America context

Changing geographic priorities

• 1970s-90s: LA primary target

• 2000-10: refocusing toward poverty hot spots eg Andes, Central America

• 2011-: rising GNP, donors shift to Africa and south Asia

• Implications for CGIAR research in LA?

Genetic resources and crop

improvement

Screening sweetpotato for heat tolerance

• Evaluation environments (N. Peru):

- heat stress (summer)- no-heat stress (winter):

• Material: 1973 germplasm accessions CIP genebank

• Key traits: heat tolerance, early bulking, and yield

Experimental site in Piura during winter.

Yields of storage roots vs. pencil roots represent an indicator for heat tolerance.

Aerial picture: summer 2014 heat stress exposure at maximum storage root bulking

Thermographic image: summer 2014 heat stress exposure at maximum storage root bulking

Remote sensing: fast throughput method to screen effects of heat on biochemical and physiological processes

Results

• 15% sweetpotato

germplasm heat stress

tolerant: 305 clones with

yields >12.2 t ha-1 under

stress

• Considerable genetic

variation heat stress

• Large pool favorable

alleles to heat stress

• Large and sustainable

genetic gains expected

Participatory Variety Selection: “mother & baby” trials(Patacancha – Cuzco)

Released:

• 2007: Pallay Poncho

(INIA 311)

• 2007: Puka Lliclla

(INIA 312)

• 2010: Altiplano (INIA

317)

• 2013: Kawsay (INIA

320)

• 2014: Poderosa (La

Libertad)

Varieties released

Participatory varietal selection: gender

• Gender filter: methods and approaches that help identify opportunities to better include women in participatory processes

• How to Conduct Participatory Varietal Selection in Potato: A Gender Responsive User Guide”

• Open-access digital platform that allows researchers or agricultural extension workers to upload their data and generate the analysis

Implications LA?

• Sweetpotato:– LA source of germplasm (genebank) & testing

environment

– LA NOT primary target

• Potato:– LA source of germplasm, testing environments and

validating research methods (gender)

– Responding to local needs

– LA primary target, but also relevant to global agenda

– BUT resource constrained – lost breeding networks (Red LatinPapa)

Protection Organizations

Strengthening capacities and increasing preparedness for Foc TR4 in LAC

Impact in LAC:• Threat of TR4 recognized by all national plant quarantine agencies in LAC

• Five countries LAC with advanced contingency plans (Ecuador, Colombia, Costa Rica, Mexico, Guatemala)

• Response to simulated outbreaks in Ecuador and Colombia – capacity testing

• World Banana Forum/Latin America electronic discussion group on Foc TR4[ MUSALAC working group on Foc and TR4]

• Regional plant protection agencies in Latin America to IPPC: [“Americas free of TR4”]

• New regional action plan by OIRSA building country by country

Impact globally:- Regional contingency plan OIRSA as model for SS Africa and Asia

Implications LA?

• Global pathosystem, needs global response

• Institutional innovation from LA model for Africa and Asia

Use a long drying tube even at small-scale

Next steps

• Blueprints for a small-scale optimized flash dryer based on model developed in Colombia (CIAT, Univalle, CIRAD 2015-2016)

• Construction Colombia planned August 2016

• Optimized flash dryer for training of processors from Colombia, LAC, and further away (Africa…)

Participatory Market Chain

Approach

Participatory Market Chain Approach: gender research

• Extensive experience in the Andes with PMCA

• Innovation in potato value chains

• BUT – gender not adequately considered

• South-south learning

• Prototype guide in testing

Implications LA?

• Cassava processing:

– Global study on downscaling

– Draws on LA experience in processing

• PMCA:

– South south learning on value chains and gender responsiveness

Impact studies

Adding fingerprinting to standard adoption/impact studies (cassava)

• Adoption/impact pilot study in Cauca Colombia• 305 cassava growers in 19 municipalities• Self-reported farmer data• For each cassava variety reported by household took

planting material sample• Cassava samples replanted in greenhouse• Analysis of DNA using Single Nucleotide

Polymorphisms (SNPs) based on fluidigm genotypingand Nei index

• CIAT chip of 96 SNPs able to identify all CIAT improvedvarieties and most used accessions from genebank

Results: Identification from DNA fingerprinting (334 cassava varieties)

Unica significant adoption in China – SIAC study

Implications LA?

• Cassava impact study:

– Cauca valley not primary target cassava breeding

– Laboratory to validate use of SNP chip in adoption studies

• Potato impact study:

– Contribution to key staple with strong rural prosperity dimension in host country

– Spillover

Wrap up: CGIAR case study in Latin America

• Diminishing share of CGIAR investment in Latin America:– Numbers of beneficiaries– LA countries became middle income

• CGIAR: need to maintain global presence as focus shifts to Africa & S. Asia• Latin America:

– genetic resources, technology, laboratory and “homologues” for foresight egsweetpotato heat tolerance and cassava processing

– part of global agricultural patho-system eg TR4– significant target geography – climate change, and biodiversity eg native potatoes

and breeding– natural resources management, Andes as vulnerable agro-ecosystem – interface

with Amazon– imperative to maintain relevance in countries hosting CGIAR headquarters eg

potato impact study

• New modalities for resource mobilization
