Agriculture is the back bone of African economies
Related agriculture and food products support a greater part of other sectors of the economy
This poses challenges to the environmental and is uncompetitive both nationally and internationally
Thus there is need for resource use diversification and sustainable utilization of crop based products

![Page 4: Developing an African bio-resource based chemical industry](https://reader034.fdocuments.net/reader034/viewer/2022051414/55a6e09f1a28abc4408b46c4/html5/thumbnails/4.jpg)
African countries are running on an informally run crop based a pseudo bio-economy
Potential to augment the already anticipated independence from agriculture led economy
Resources to be exploited still need to be identified and developed
A GOOD EXAMPLE IS EXPLOITING HIGH BIOMASS CROP BASED SOURCES SUCH AS CASSAVA
This crop is grown widely in Africa
![Page 5: Developing an African bio-resource based chemical industry](https://reader034.fdocuments.net/reader034/viewer/2022051414/55a6e09f1a28abc4408b46c4/html5/thumbnails/5.jpg)
New industrial proven and scalable bioprocesses and systems are available
Cassava is adaptable to various bioprocessing organisms for industrial products production
Economic feasibility of the processes involved in exploitation of cassava already proven
Bio-product (specifically food based and bio-fuels) production processes already established
Cassava starch and starch processing wastes have an established significant industrial value

Effect of the exploitation processes on land and water availability need to be minimized or completely outdone
No negative interactions between the interventions and the existing economy
A comprehensive sustainability plan is needed before using cassava as chemical industry based bio resource
Potential sustainability and eco-efficiency issues can be pursued
Encouragement of decentralized and localized system
Use already existing and decentralized models such as ICT and environment (other case studies)
![Page 17: Developing an African bio-resource based chemical industry](https://reader034.fdocuments.net/reader034/viewer/2022051414/55a6e09f1a28abc4408b46c4/html5/thumbnails/17.jpg)
Investment Risks Small portion of products and services can be easily commercialized
Bureaucracy and standardization (for example inability to accept fuel blends)
Poor market to research linkages lead to product unacceptability
Inability to attract the relevant human resource Low technical competence in this field
Lack of talented and interested technology movers and product marketers
Technology challenges No relevant technologies for bio prospecting, bio analyses
Sustainability and environmental challenges

Agricultural pests and diseases
Low production and inadequate post-harvest management.
Limited use of appropriate proven technologies in agricultural production and post-harvest management (rudimentary production process).
Poor linkages between key actors in knowledge or innovation systems
Shortage of enterprenual skills
Poor marketing and communication strategies
