7.5.3. Crop Suitability and<br />

Soil Fertility Mapp<strong>in</strong>g us<strong>in</strong>g<br />

Geographic Information<br />

System (GIS)<br />

This k<strong>in</strong>d of study entails <strong>com</strong>b<strong>in</strong><strong>in</strong>g<br />

and analys<strong>in</strong>g agro-environmental,<br />

soil <strong>in</strong>formation, water <strong>in</strong>formation<br />

and crops biological requirements<br />

for growth 82 . It considers soil<br />

samples analyses. An important<br />

work has already been done by<br />

MOA about description of soil<br />

chemical properties, result<strong>in</strong>g<br />

<strong>in</strong> a description of soil fertility.<br />

Overlay<strong>in</strong>g <strong>the</strong> agro-climatic map<br />

with land suitable for farm<strong>in</strong>g<br />

practice map and soil fertility<br />

map, a crop suitability map could<br />

be developed.<br />

It would <strong>the</strong>n be possible to propose<br />

more accurate re<strong>com</strong>mendations<br />

about irrigation practices accord<strong>in</strong>g<br />

to soil types (Guidel<strong>in</strong>es about<br />

irrigation practices <strong>in</strong> sal<strong>in</strong>e soils<br />

for example).<br />

irrigated planted areas between<br />

WAJ and MOA. Indeed, WAJ<br />

calculations are based on data<br />

from 2002.<br />

A coord<strong>in</strong>ation project between both<br />

M<strong>in</strong>istries would be <strong>in</strong>terest<strong>in</strong>g to<br />

harmonise <strong>the</strong> <strong>com</strong>mon data.<br />

It would be <strong>in</strong>terest<strong>in</strong>g to establish<br />

Information Centers <strong>in</strong> <strong>the</strong> MOA<br />

branches. They would be a way<br />

of shar<strong>in</strong>g <strong>the</strong> acquired data with<br />

farmers, who could <strong>com</strong>e and<br />

ask for <strong>the</strong> any <strong>in</strong>formation <strong>the</strong>y<br />

need about market, soils, water<br />

crop requirements… This database<br />

should be kept and updated by <strong>the</strong><br />

MOA directorates.<br />

It was mentioned previously that<br />

data from WAJ and data from MOA<br />

are not <strong>com</strong>patible. For example,<br />

<strong>the</strong>re is a large difference between<br />
