Tunisia, the agricultural sector in the face of natural disasters
The heavy rain, hail and rising water levels in mainstreams and rivers have also affected the agricultural sector which is undergoing soil degradation, driving production down.
The agricultural sector in Tunisia
Agriculture ranks high in the Tunisian economy, contributing up to 10% in GDP and employing 14% of the labor force. The sector also contributes to the commercial balance, accounting for 10% of exports.
The agricultural activity is conducted over 10 million hectares throughout 516 000 farmlands. The income for a large part of the population depends on agriculture and the use of natural resources. The sector, highly important, is evolving in a fragile natural environment, with a highly sensitive dependence on weather conditions.
Furthermore, experts forecasts for the upcoming years are not upbeat, with several regions, especially in the Center and in the South, expected to sustain weather conditions most unfavorable to agriculture: temperature variations, heavier rainfall, frequent droughts…
Some experts are even more downbeat, predicting that under the effect of extreme phenomena, some activities are likely to vanish in the future.
The agricultural Tunisian sector suffers some constraints among which:
- farmland severances: 50% of farmlands are below five hectares in size, belonging to small farmers who sustain important losses in recurrent fashion,
- limited natural resources: hardly arable lands, severe erosion,
- poor average rainfall: irregular rain in space and time,
- increasing frequency and severity of extreme phenomena such as droughts and floods: hail and torrential rain are the most dreaded phenomena by farmers,
- rising temperatures by 2.1 C° and decrease in rain by -10 to -30% by 2050,
- increasing severity of extreme phenomena with gradual decrease of arable lands.

Tunisia: Impact of natural disasters on agricultural risks
Natural disasters have caused 172.3 million USD in losses for the Tunisian agricultural sector during the 2011-2016 period. The 2017/2018 season, alone, reported 82 million TND (33 million USD) in damage, with the State covering only 6% of the total losses, that is 4.9 million TND (1.9 million USD). The remainder is borne by farmers.
Most widespread risks are droughts, floods, windstorms, hail, snow, frost, forest fires, diseases, insects and faunal pests.
Breakdown of damages per type of agricultural risks: 2011-2016
Floods remain the most frequent risk, with tremendous impact on both production and infrastructures.
