Global climate change and agricultueTRANSCRIPT

Agriculture deals with: 1. Crops,2. Livestock,3. Agro-forestry, and4. Aquaculture
and is critical for: •Poverty reduction•Economic development and•Food security
Constraints of crop sector1.Climate change
2. Immense water shortage3. Salinization of originally productive soils4. Depletion of SOM and unbalanced plant nutrition5. Yield gap/stagnation/decline6. Profitability: increasing cost and deceleration in TFP (Total Factor Productivity) growth,7. Lack of diversity (varieties, cropping system)
A holistic approach mitigating all these problems is required
The Challenge By 2050, the global population will reach 8.9 billion and per capita food consumption will rise above 3100 Kcal per day,
Require 70% increase in agriculture productivity from 1600- 1680 Mha of cultivable land not sufficient to produce the requirement of 40% increased population,
hence 90% of the required increase will come from intensifying farming practices and higher yield
From 1960 till to date, crop yields have increased globally by 77% just by exploiting the genetic potential which has largely been exhausted and required re-evaluation
Many varieties currently are producing only 30-35% of what is agro-ecologically attainable under comparable environments climate change has further aggravated the situation
What are the options?
i. Get help from Genetic engineering/smart breeding/
environment friendly genesor
ii. Revisit strategies
Option-1:GE/smart breeding/environment friendly genes
Recommendation from Lok Sanjh Foundation and the Pakistan Dehqan Assembly (> 600 small, landless farmers and tenants participated)a)Withdraw the Agreement of Intent with Monsanto to introduce Bt cotton,b)Protect Basmati areas from GE and hybrid rice production c)Right to Food should be given priority instead of breeder’s right,d)WTO should be kept out of food and agriculture-related issues,e)The Government should immediately withdraw the Corporate Agricultural Farming Policy and land should be distributed to landless and small farmersf)The agriculture research system must be revamped to focus strictly on local seed varieties
Will option-1 work?
Option-2: Revisit strategies
For this we have to think:i. What is required for crops?ii. What we have?iii.What we need? andiv. What we can have?
What is required in crop sector?Resources comprising land, water and manpower
to make agriculture:
Productive: so that share in GDP can be increased from 19.6 % to 27% by 2015
Profitable: so that it can generate more income with less expenditure and should produce
exportable commodities Competitive: So that it can reduce poverty through
providing livelihood and creation of jobs in the rural areas and Sustainable: so that it should be able to absorb shocks
and remain productive forever.

Water 90.00 MAF 8500 Cusecs in GTC2010-2011 6000 Cusecs in KC
5155 Cusecs in RC19655 Cusecs in total(app. 14.23 MAF)
Manpower: 45% (2010-2011) All those related with newly irrigated areas
What about climate change?
Climate change will have negative impactsWill lower yields (the varieties in hand will not work)
Will increase prices (we are witnessing this)More malnourished children (already 40%)
Require large additional expenditure to:i. Build infrastructureii.Purchase the climate ready genes (55 such families are available or )iii. Pay royalties for growing the patented varieties required to combat adverse impact of climate change
De we have enough resources?

Daily per capita calorie availability with and without climate change by the year 2050
*70% increase is require to meet the demand of increased population , additional increase would be required to meet this deficiencyNCAR: National Center for Atmospheric Research, USACSIRO: Commonwealth Scientific and Industrial Research Organization, Australia

The situation will not remain the same with varieties in hands
Production will reduced in Pakistan by < 25%
What about Afghanistan?Will smuggling increase?
Positive aspect: 100 mm more rain. New avenue for cultivation, can increase export to IRAN and Afghanistan
Do we need strategic planning?
Commonwalth Scientific and Industrial Research organization
100-200 mm more rain in Pakistan and in some parts of Iran and Afghanistan will bring new land under cultivation especially in Baluchistan
National Center for Atmospheric research, USA
Hope:
As a consequence of rain,
Increased production will meet the target sets in the vision 2020
How to make the gains sustainable1. Plan strategically (action Pakistan)
2. Develop climate friendly (action global level)
3. Food production for human consumption be given priority over consumption demand
(Action industrial countries) 60% for human, 40% for animal feed which is equivalent to annual calories need of 3.5 billion (> half) of the total 6.6 billion population)
3.Follow the food web and not the food chain(Action developed countries)
Is this not what was suggested by the poor and illiterate farmers in remote Sheikhupura district ?
4. Keep, preserve and save genetic diversity (animal, plants and fishes) because climate crisis need this more than hunger crisis,
(Action researcher/research organization)
The uncertainties of climate change demand a complete rethink of
research especially the breeding priorities. Plant breeders needs to nurture species and genetic diversity in the field
HopefullyIt will be the peasant
farming system that will use genetic diversity and
help crop withstand climate change
because
They did it in the past
Why can’t they do it now?
