RAINFALL SITUATION IN NIGERIA

The rainfall amount in 2012 was substantially higher than of 2011. In the South-South

Zone rainfall was overwhelmingly high in 2012. The rains started in April in the North-

East and North-West Zones. Most of the states in the South-West, South-East and

South-South Zones recorded their first rains in January as against February in 2011.

There were variations in the commencement of rain in North-Central Zone. Benue, Kogi,Kwara states and FCT recorded their first rain in February while the rains commenced in

Nassarawa, Niger, Taraba and Plateau in April.

The total rainfall amount received from January to December 2012 in the South-South

Zone was in excess of 2500 mm followed by the South-East (>1500 mm) and South-West

(>1100 mm). North-Central received rainfall amount slightly above 900 mm while North-

East and North-West recorded an increase of 29% and 18% respectively in 2012 (above

that of 2011).

Heavy rains that resulted in flooding occurred this year across the country in Kogi,

Kwara, Lagos, Taraba and Adamawa states with attendant severe crop damage, some

casualties and displacement of several settled farming communities. The South-West

Zone recorded higher number of rainy days than the Northern Zones while the South-

East recorded slightly higher rainy days than the South-West. Despite the heavy rains,

dry spells were reported in Kwara state (although it was only for a few days). The rainy

season extended beyond long term established duration in most parts of the country.

This invariably induced a longer period of cloud overcasts that impeded optimum solar

reception on crop surfaces. The early on-set of the rains enabled earlier planting of

crops but the extended rainy period raised the fear of damage on early planted crops

that matured during the rains because sun drying option was constrained. The cloudy

nature of the season induced concern for mycotoxin, especially feasible aflatoxin which

the farmers and consumers must contend with.

As earlier stated, the rainfall amounts received especially in August and September

across the country were extraordinary. This resulted into flooding with serious

economic damage/loss to crops and habitats. Although all crops were affected,

phenomental damage was recorded in maize, rice, cocoyam, cassava, fish and soybean.

The release of water into Nigeria from a dam in Cameroon Republic in early September

compounded the situation resulting into colossal loss of agricultural products especially

along the shores of River Niger and River Benue (the confluence town of Lokoja and all

the states in the Niger Delta). The flood overflown the banks of River Niger in Lokoja and

Anambra, Delta, Bayelsa and River states impeded movement of commuters andvehicles to the extent that millions tons of perishable agricultural commodities were lost

in transit. The Federal government reported that in 27 states, over two million people

were displaced by the flooding.

Generally, rainfall distribution during 2012 cropping season in the country became an

issue of concern to all stakeholders. Flood resulted from the usual 3 to 4 months of rainy

season with substantial loss of life, properties and agricultural commodities was an issue

Rainfall Distribution in Nigeria

Figure 1: Annual Rainfall (mm) of selected stations in NE for 2011 compared to 2012

The comparative rainfall data for 2012 and 2011in the six agricultural zones of Nigeria

are presented in this section. The rainfall amounts and rainy days increase from the NE

down to the SW and SS. Generally, rainfall started between the month of January and

February in the South while most states in the North received their first rainfall in the

Months of March and April in 2011 and 2012.

NORTH EAST ZONE

In 2012, the rains started in April with the exception of Yobe state. It became fully

established in late April across the zone. A total amount of 2682 mm was received in the

month of April compared to 62.9 received in 2011.More rainfall occurred in July, August

and September in 2012 than those of the corresponding months in 2011 across the

zone.

Comparative data between 2011 and 2012 revealed that all the States within the zone

received more rainfall from January to December 2012 than in 2011 as shown in Figure

1 with Bauchi State receiving higher rainfall. Cases of serious flooding were reported in

some parts of Yobe and Adamawa states. The rainfall distribution and quantity acrossthe zone were considered adequate for crop production except for the serious flood

that resulted in the destruction of crops in Adamawa and Yobe states.
