How to Use

The author team tried to develop a website that is in large parts self-explanatory. The intro-page is divided into four buttons. If you read this, you obviously found the How to use button.

As soon as new tools are realized, you'll find under this button descriptions about the tools' conceptual framework and an introduction on how to manipulate the software.

Technical Implementation

The entire toolbox was realized based on open source software and can be easily extended or applied to other regions of the world. The server implementation, in summary, is based on the following software stack:

Land Evaluation

Under the button Land Evaluation you'll find a general land evaluation tool (LET) for eastern West Africa that was developed strictly based on the FAO framework for land evaluation. A similar tool was developed for Tanzania in Eastern Africa that you can find here.

A specific application of the LET is the micro dosing. Micro dosing is an agricultural technology that uses hill-placed fertilizer application in order to reduce application rates but sustainably increase crop yields. A link to a publication you'll find here (micro dosing publication).

Since the micro dosing technology reduces costs for fertilizer and has a reduced risk for return on investment, it is interesting to identify suitable intervention regions. This is possible via this tool.

Spatial Data

The Spatial Data button leads to regionalized data that have been collected during the DecLaRe project. These concern, for example, drone images or soil maps at village scale in the intervention zones.

Other Tools

Finally, you'll find under Other Tools a web based (spatial) software that allows the identification of elemental micro-nutrient deficiency in humans depending on the diet. Here you can manipulate the human diet and get as a result an evaluation whether this leads to a sufficient or insufficient uptake.
