Desertification in Africa: 319 million hectares of Africa are vulnerable to desertification
Desertification is the spread of desert-like conditions in arid and semi-arid conditions. It is a result of pressure from both climatic and human factors. Desertification in the Sudan has been accelerating at a faster rate over the last two decades, leading to loss of arable land. The main factors contributing to desertification include drought, population growth, the spread of extensive agriculture, deforestation, rapid urbanization, , the lack of economic institutions and the absence of social institutions which have tended to reduce the capacity of the local people to cope with the resource degradation problem.
The desert was rolling, unimpeded, into communities. Unprecedented sandstorms created chaos: A teacher told me how the sand had poured in through school windows as she taught. A father told me of how the sand would blanket his children as they slept.
In the Republic of the Sudan a sum of 500000 km is directly affected by desertification. More than half of the Sudanese population lives within this zone which is and always has been the most active economic region with the largest towns of the country.
People described the desert as a “devil” that crawled and clawed its way into their homes to drown them. Standing on sand dunes, I was shocked to hear that below my feet were entire villages.
in 2016 Massive Dynamics R&D starts -Initiatives to arrest the desert encroachment include improved cultivation methods like UAVs plant cultivation & health monitoring management, reforestation and integration of livestock and crop production systems, coupled with good linkages to UAVs industries.
UAVs Measures To Combat Desertification In The Sudan
SAP (Smart Agricultural Payload) project used in the context of vegetation index and environmental research its a lightweight autonomous airborne platforms which collect data along pre-planned flight trajectories.
1-SAP-High resolution mapping provides data for on-going analysis and monitoring of ecosystem health, shelter-belt Monitoring & Evaluation to reverse the process of land degradation& desertification
For this purpose, drones can be equipped with different sensors such as optical and thermal sensors.
While satellite and airplane based imagery procurement is used for large areas, drone based imagery is a competitive option for areas of up to 10.000 hectares. The low flight altitude allows the procurement of detail-rich imagery without atmospheric interferences.
Main advantages are:
Flexibility to procure imagery everywhere and at any time.
High resolution of 15 cm/px to 1 cm/px.
Lower costs in comparison to plane-based aerial photography
The project data is delivered in standard formats for easy integration in GIS and 3D software applications.
2-SAP- planting mechanism allows planned planting locations for combined millet / Acacia , trees to reduce desertification & land degradation
Our drone can plant trees, increase harvests and reduce crop damage. And WE are bound by shared belief that Africa can change its destiny with technology.
A great green wall of trees is being built across the length of Africa to try and combat this.
