Millions of people
in many developing countries do not have enough food to meet their
daily requirements and a further more people are deficient in one or
more micronutrients [
1].
Thus, in most cases rural communities depend on wild resources
including wild edible plants to meet their food needs in periods of
food crisis. The diversity in wild species offers variety in family
diet and contributes to household food security. Numerous publications
provide detailed knowledge of edible wild plants in specific locations
in Africa [e.g. [
2,
3] and [
4]].
All showed that wild plants are essential components of many Africans'
diets, especially in periods of seasonal food shortage. A study
conducted in Zimbabwe revealed that some poor households rely on wild
fruits as an alternative to cultivated food for a quarter of all dry
season's meals [
5].
Similarly, in Northern Nigeria, leafy vegetables and other bush foods
are collected as daily supplements to relishes and soups [
6].
In Swaziland, wild plants is still of great importance and contribute a
greater share to the annual diet than domesticated crops [
7]. Various reports also noted that many wild edibles are nutritionally rich [
7-
9]
and can supplement nutritional requirements, especially vitamins and
micronutrients. Nutritional analysis of some wild food plants
demonstrates that in many cases the nutritional quality of wild plants
is comparable and in some cases even superior to domesticated varieties
[
10].
Earlier
works showed that about 8% of the nearly 7000 higher plants of Ethiopia
are edible. Of these, 203 wild and semi-wild plant species are
documented [
11].
Still many more wild species are believed to be edible and undocumented
yet. More recently, some ethnobotanical studies have undertaken in some
parts of the country. However, the majority of these studies have dealt
with medicinal species and little emphasis has been paid to wild edible
plants. This study has therefore sought to document indigenous
knowledge related to uses of wild edible plant species and to assess
the existing threats to wild edible plants in the study areas.
