Cleaning the Chemical Past

 

 

Seka Chekors is not too different from many other similar towns as it struggles to pull itself out of the poverty that grips much of one of the poorest nations on the planet. One additional challenge to the town's residents that puts it in a unique category of towns is resurfacing after being relegated to bad memories for many old enough to recall.
 

One of the 230 districts within Jimma Zone in the Oromia Regional State, the township Seka Chekors is Located 347Km southwest of Addis Abeba. Twenty-thousand people inhabit this rural town 20Km along the main road from Jimma township.
 

Springtime in 1991 not only brought the normal belg rains but also the overthrow of the Derg military regime in power since 1974 and installation of the Ethiopian People's Revolutionary Democratic Forces (EPRDF). The ensuing power vacuum rendered government facilities vulnerable to looting and general insecurity of property.
 

In Seka a number of the residents stormed the Ministry of Agriculture and Rural Development (MoARD) warehouses removing whatever their hands and shoulders could bear.

 

Ibrahim Abageno, a 50-year-old resident of Seka and father of three who earns a living growing chat and corn as well as cattle ranching, vividly recalled what went wrong back then.

 

"The change in government left the warehouse unguarded," Ibrahim told Fortune.
 

Some of the materials were a rather nefarious bounty and turned out to be more of a curse than a treasure.
 

Expired chemicals, such as DDT (dichlorodiphenyltrichloroethane), a colourless pesticide that kills insects and is also harmful to animals and humans, was among the items carted off by ecstatic looters.
 

This chemical was heavily used in many parts of the world until later being found to possess effects reaching far beyond the intended purpose of ridding crops of pests. DDT was pivotal in the formative stages of the United States (US) environmental movement beginning in the 1960's as Rachel Carson's investigative journalism book Silent Spring revealed the chemical's role in killing huge bird populations in the US's Midwest.

 

Along the hurried journey from the warehouse to home some of these people chose to empty the chemical from the containers thus spreading the toxin on various plots of land in the area.
 

Soon the impact started to become tragically apparent in the lives of residents, domestic animals and the environment, area residents told Fortune.
 

"Sadly some of these people involved in the robbery of the warehouses must have mistaken the fine white-powder stored in the containers for wheat flour and made porridge out of this chemical only to die instantly," Ibrahim recalls.
 

Ibrahim's three cows were among the 20 cattle were found dead after grazing on contaminated grass.
 

"Remains of dead hyenas were also found not too far away from the dead domestic animals as well as scavenger birds," Ibrahim recounts.
 

In 1992, concerned by what was going wrong, the Agriculture and Rural Development Bureau of Jimma in collaboration with Jimma University, formed a committee to bury the chemicals scattered here and there.
 

Fifteen years down the road, however, this chemical is now more than a disturbing memory as the potential for its effects are feared to be revived. About 500m away from where these obsolete chemicals were buried a well was sunk that is servicing many residents in the town with potable water.
 

Teshome Tafesse, plant health clinic expert under Jimma rural and agricultural bureau, is among those concerned that the hasty manner in which the chemicals were disposed was a short-term solution that did not close the tragic chapter in the book of Seka Cherkosaa
 

"Although the move taken to burry the chemicals back then was useful in the short-run in the face of emergency, it is time to find a permanent solution," Teshome told Fortune.

Fears of toxic chemicals haunting citizens with their disastrous effects are not limited to Seka Cherkosaa.
 

In 1996 the government identified 1,500tn of obsolete chemicals that needed proper disposal. Upon forming a partnership with international institutions such as the Food and Agriculture Organization (FAO) in 1998, the government began a project to incinerate the expired pesticides using international experts and finance.

 

After funds were made available and these institutions assessed the situation from 2000-2003, under the auspices of FAO, the United Nations (UN) established specific mechanisms to remove the pesticides.
 

This programme cleared a total of 243 chemical-prone sites through the successful incineration of 1,575tn of obsolete pesticides of which 1,511tn have been safely repacked. In 2004 an additional 705 sites were cleared having safely repacked 1,000tn of obsolete pesticides.

 

The work is not complete however, as the country's stock of harmful chemicals is not thoroughly depleted.
 

From the period of 1983-1993 Ethiopia imported around 4,000tn of pesticides annually at a cost of 21 million dollars.
 

"In order to advance into the next step based on what we have accomplished we are now prepared to conduct comprehensive studies," Biratu Oljira, national project manager under the Ministry of Agriculture and Rural Development, who says further progress is being made, told Fortune.

 

Two months ago 850tn of obsolete pesticides have been repacked and are being transported to a major collection centre in Addis Abeba. An additional 640tn of these chemicals from as many as 593 sites are to be shipped overseas for incineration.

 

The overseas incineration would be done after these chemicals are safely repacked and brought from seven major sites - Mekelle, Bahir Dar, Kombolcha, Awassa, Nekemt, Jimma and Dire Dawa - where they are stored to the main collection centre in Gotera.

 

These chemicals originate from numerous places and are intended for various agricultural uses after being imported by various state farm enterprises and stored at MoARD facilities. However, their short life span relegates great volumes to obsolete states. Although many chemicals are usable for about two years of manufacture, the transport period to the site of intended use often cuts this time by six months, a loss of time that is often too great for recovery.
 

Once these chemicals expire they become highly poisonous and dangerously harmful to all living things, according to a chemical expert in the private sector.

 

Residents of Fiche, located 112Km north of the capital in North Showa Zone of the Oromia Regional State, suffer from the pungent smell emanating from these warehouses. While the aroma is a nuisance, the process with which these pesticides are transferred to the site from where they would be transported for incineration has become more of a danger in the eyes of some residents.

An expert from the District's Agriculture and Rural Development Office told Fortune the chemicals are being exposed to the soil and air and causing employees to fall sick.
 

"Although the first phase of incineration of the chemicals is given priority, the warehouses that have been storing the chemicals should be closed down and subsequently cleaned up," the expert said. "In order to avoid possible contamination of the soil around this area the surface should be dug at least one metre deep."

 

The national project sets three phases by which to rid the nation of harm from the expired pesticides. The first one starts with shipping the chemicals overseas to be eliminated as such chemicals require 1,200 degree centigrade heat to be effectively incinerated, a very costly proposition.
 

The second and the third phases would deal with destroying the containers of the chemicals and removing the surface soil where contamination is found, as this land is sterile and only poses a threat.
 

The nationwide effort, however, does not address the household level as many families are thought to be using the dangerous containers.

 

Tadesse Amerra, a public health professional and coordinator of the African Stockpiles Programme NGO voiced professional concern that the exposure of obsolete pesticides has tremendous negative impact on the safety of human habitation and would affect the delicate balance of biodiversity.

 

"Some of the main consequences that would result through the exposure of these chemicals are cancer, miscarriage and sterile, Tadesse told Fortune. "Once the chemical entered into the human body, it would lodge in fatty tissue and cause serious illness."
