Seeds for Needs: what is all about

Upscaling seeds for needs

Climate Change: Is It Real?

Climate Change: Some Evidence

•Climate change, floods, droughts, unpredictable temperatures and rainfall

•Changing pest and pathogen populations and levels of pollination efficiency

•Increased soil and land degradation

Major Environmental Threats to Sustainable Production

Adaptation to climate change: recommended actions by the IPCC

Improving crop tolerance to high temperature is a frequently

identified adaptation for almost all crops and environments

worldwide as high temperatures are known to reduce both

yield and quality

Adaptation to climate change: recommended actions by the IPCC

Improving gene conservation and access to extensive gene

banks could facilitate the development of variety with

appropriate thermal time and thermal tolerance characteristics

Adaptation to climate change: recommended actions by the IPCC

Indigenous Knowledge (IK) has developed to cope with

climate hazards contributing to food security in many parts of

the world

Ethiopian Green Economy Strategy

Target set for agriculture:

• Boost agricultural productivity (+40% increased production for major crops such as teff, maize, wheat);

• Intensify agriculture through usage of improved inputs and better residue management resulting in a decreased requirement for additional agricultural land that would primarily be taken from forests;

• Create new agricultural land in degraded areas through small-, medium-, and large-scale irrigation to reduce the pressure on forests if expansion of the cultivated area becomes necessary

• Introduce into cultivated areas lower-emission agricultural techniques, ranging from the use of carbon- and nitrogen-efficient crop cultivars to the promotion of organic fertilizers

Under conditions of change

(reducing the probability of loss of agricultural

productivity in the future, while enhance productivity

today)

The fundamental question:

Productivity and reduced vulnerability

How can we ensure that agricultural productivity increases are

accomplished in ways that create and enhance ecosystem

resilience and services for the poor?

Unexploited Potentials in Landraces

• disease resistance (Leppik, 1970; Negassa, 1986; Klindworthet al., 2007; Jemanesh et al., 2013);

– e.g. Ethiopian landraces are the source for Sr13 gene, which is responsible for stem rust resistance

• Drought tolerance/resistance (Tesfaye, 2001; Mondini et al., 2010, our study)

• Very diverse for qualitative and quantitative traits

What We Did

Phenotyping trials

The genotypes, 373 landraces and 27 improved wheat varieties, were phenotyped attwo locations (Hagreselam and Geregera) in 2012 and 2013 main cropping seasons for 10important traits:

A. Phenological traits

• days to 50% booting (DB);

• days to 50% flowering (DF) and;

• days to maturity (DM)

B. Morpho – agronomic traits

• plant height (PH);

• number of effective tillers per plant (NET);

• spike length (SPL);

• number of seeds per spike (SPS);

• above ground dry biomass (BY);

• grain yield (GY).

The process

Strengthening Community Seed Systems

Upscaling and Outscaling Seeds for Needs

Reaching more farmers and for more crops

• Capacity development

• Approach institutionally embedded in extension services and agro-

dealer networks

• Methodology improved and expanded using ICT-based solutions

Crowdsourcing plan

• Initial investment for a new crop such as teff, sorghum, pulses,

targeting 500 farmers/site for 2 years

• Crop technical characterization

• Participatory evaluation

• Capacity development

• Crowdsourcing

• Subsequent distribution through crowdsourcing: targeting

10,000,000 HH over 3-4 years including seed multiplication

Strengthening Seed Systems

Institutional

genebanks(National, private, experimental

stations, universities…)

Community Seedbanks

CGIAR genebanks

Regional

genebanks

To strengthen the seed network one needs more than one

seed bank/landscape (roughly 10 to reach 10,000

households).

Goal: to reach 200,000 households in 20 landscapes

across the country
