Introduction Climate change is a shift in the mean state of
the climate or in its variability, persisting for an extended periods time (decades or longer). It could be due to……..
Natural changeso Externally- extra-terrestrial systems. o Internally-ocean, atmosphere and land systems.
Prolong Anthropogenic Activities-o Burning of fossil fuelso Decomposition of animals or plants materials o Deforestation for construction & development
etc.

Introduction Adaptation- is a measure of resilience or
resistance to negative climatic stimuli as well as the coping capacity of a community or nation in response to these changing conditions (GFCS, 2012).
Vulnerability- is the degree to which a system is susceptible to, or unable to cope with, adverse effects of climate change, including climate variability and extremes.
Indigenous Technology- is the knowledge /practice by the native inhabitants of a country that constitute an important part of its cultural heritage………..to manage disaster or risk

Introduction Impacts Scenario in Nigeria
Flooding around River Niger displaces Millions from their homes inKogi, Benue, Imo & Edo leaving millions of land transport travelersstranded Lokoja city and some on tree tops as the flooding persist .
Premium Times 09/2012 reported that NEMA is currently campingover 10,000 displaced flood victims in Kogi and Benue states.Cause- Cameroon Govt. released water from the Lagdo Dam, East ofNigeria .Source: (Premium Times ,2012)

Why High Level of Vulnerability
Their greater reliance on climate-sensitive sectors ……….
o Agriculture, Lands and Resources from it (USAID, 2007). Their geographical location. Low income status. Low institutional capacity to address these
imparts.

Research Gap
Programs, activities & institutional strategiesimplemented by policy makers to mitigate andadapt to climate change effects often do nottake rural poor communities into accountproperly and ……increases their vulnerability toclimate shocks.
However, they have close traditional relationshipwith their environments & uniquely endowedwith some strategic potentials of resilience to CC shocks
Information on these unique strategicpotentials of adaptation to climatevariability and change are lacking.

Digging of deep trench “Ukoro ibo”
Laying farmyard/ weeds ……
By March …make big mount
Sow their yam
These ensures better yield

Expected outcome
Nutritional characterization of these underutilized crops and to compare these with two conventional/exotic species
Findings of this work will be converted into a
o Working paper to scale up awareness on their Nutritional Values…….
o Policy brief to guide future policy and the decision making process on their incorporation into manures in public places e.g. schools, hospitals and if possible to inform policy in other parts of Africa .
