Last 9th of October of 2015, our colleague Andnet Bayleyegn graduated after defending with great distinction (très honorable) his thesis in Montpellier, France.
During three years Andnet developed his PhD project between Montpellier Supagro (France) and University of Catania (Italy) in collaboration with the international centre of insect physiology and ecology (icipe), Nairobi, Kenya and the French Agricultural Research Centre for International Development (CIRAD). He conducted a research work based on the behavior, ecology & control of legume flower thrips, megalurothrips sjostedti (trybom) in cowpeas (vigna unguiculata l. walp) towards the development of an integrated pest management program in Kenya, with the aim of finding alternative pest management strategy which has less effect on people, livestock and the environment. The research leaded to the identification repellent plant extracts which can be used for pest management strategy in legume cropping system.
Andnet published relevant papers during this period contributing to the generation of knowledge about integrated pest management:
“Repellency of Plant Extracts against the Legume Flower Thrips Megalurothrips sjostedti (Thysanoptera: Thripidae)” which investigates how plant extracts can be used as a repellent for specific types of pest in legume cropping system.
“Farmers knowledge and perception of grain legume pest and their management in the eastern province of Kenya” which investigates how farmers identify important grain legume pests and how they are controlling them, the cultural practices practiced by the farmer and other challenges which influence production of grain legumes.
“Ecological Niche Modeling to Predict effect of Climate Change on the geographic distribution of the Cowpea pest legume flower Thrips (Megalurothrips sjostedti) (Thysanoptera: Thripidae) In Africa” Climate, especially temperature has a strong and direct effect on insect development, reproduction, survival and colonization success of insect species. In a climate change scenario, techniques developed to detect areas of climatic favorability. Those models used in species distribution models are considered to represent useful approach for detecting suitable areas of colonization and establishment of a species. Thus, he investigates present and future potential distribution of the legume flower thrips and its favorable host crop cowpea in Africa.
“Toxic and behavioral effects of 16 compounds against Megalurothrips sjostedti larvae (Thysanoptera: Thripidae)” The larval stage causes more direct feeding damage on epidermal and sub-epidermal plant tissues, causing destruction of buds, flowers and malformations of pods. Sixteen constituents of different plant extracts were tested for their effect on the feeding activity, toxicity and behavioral effects on the second instar larvae of legume flower thrips, Megalurothrips sjostedti (Thysanoptera: Thripidae).
After finishing his defence Andnet said “I am extremely happy to have successfully completed my Study! Being a father of Triplets at the last year of my study was a very difficult moment on handling academics and family matter. I Thank the Almighty God for his Blessings! Special Thanks to my supervisors for their outstanding supervision, follow-up and constructive criticism during my study period. I thank friends and families for their unreserved support until the final point”.
For Andnet, his participation in the Agtrain programme have changed his life: “The Agtrain program helped me a lot that provided me a world class academic knowledge and experience with an opportunity of meeting scholars across the globe and sharing experience. The programme also enriched my social skill and had a great place in my life with unforgettable moments and experience. Thanks Agtrain”.

The phenomenon of business incubators is remarkably expanding worldwide particularly in developing countries located in Africa. Research on agri-business incubators in Africa may help us to better understand what factors can contribute to the success of agribusiness firms. At the same time, more investigation can contribute to know what makes effective an incubation process.
Public, private and academic institutions are focusing on business incubators as they have seen the potential benefits that incubation programs have to assist entrepreneurs in creating innovative products. The benefits of an incubation program mainly focus on three levels: infrastructure (office services), counseling (business support such as training), and networking.
Benefits of an incubation program help entrepreneurs to overcome issues such as information asymmetries, competitive advantage, resource shortages, price disadvantage among others. Therefore, entrepreneurs overcoming these issues can improve their businesses; reduce risks; and increase survival possibilities. Additionally, business incubators can contribute to the local development of an area by helping start-ups in the development of their businesses. Then, benefits of business incubators can also have implications in the economic growth of a locality.
Currently, I am doing a research related to agri-business incubators in East Africa. These business incubators intend to enhance the commercialization of agribusiness products by adding value, innovation, and new technologies in the production process. Most of these business incubators target start-ups in rural areas of Kenya and Uganda. My main reason to explore more about this phenomenon is to find contributions at the firm level to enhance performance and consequently influence on the economic growth of rural areas in East Africa.
In general, more research in this field can help us to better understand the effective performance of business incubators located in developing countries, thus, being effective mechanisms to the development of agribusiness firms.

Your morning coffee has the power to wake you up, make you more productive and get you through that first meeting of the day. But does it have the power to change the lives of the people who produced it?
Colombian, Costa Rican, Ethiopian, Jamaican Blue Mountain. There are a lot of choices that you make when deciding which type of coffee to buy. In recent years even more choices have become available- Fairtrade, Rainforest Alliance, UTZ Certified, CAFÉ Practices, organic. These are sustainable coffee certifications that you may have seen indicated in the form of a little stamp on your bag of coffee. These certifications indicate to the consumer that the coffee was produced in a certain way—without the use of conventional chemicals in the case of organic, in a way that preserves biodiversity in the case of Rainforest Alliance, or in a manner that supports cooperatives of small farmer in the case of Fairtrade. In some cases the farmer is paid a premium to incentivize these changes.
It may be surprising to think that artificially high prices can cause problems for coffee farmers as well. High world coffee prices can mean that farmers over invest in coffee production, bringing new areas into cultivation, becoming overly dependent on an unstable commodity and ultimately causing an oversupply and a repeat of the cycle.
I was curious to know if sustainable coffee certifications could alleviate some of this fluctuation and lend a little more financial stability to the life of a coffee farmer. By surveying all of the Costa Rican coffee cooperatives which participate in sustainable coffee certifications, I found that some certifications seem to help protect farmers from the lowest prices. Fairtrade in particular, because it offers a minimum price to farmers, can even out the price fluctuations by mitigating market lows without augmenting market highs. Rainforest Alliance, Utz and organic certification can also help to some extent, since farmers tend to sell their crops with certification when the market is low, benefiting from the certification premium, and selling their crop to conventional (uncertified) markets when the price is high, possibly avoiding the costly audits that come with certification.
However, the benefits are limited because of the small amount of coffee that is sold under certification relative to the amount that is verified that it was produced in a standard-compliant manner. In other words, the global supply of certified coffee far outweighs the demand. In 2012 3,300,000 metric tons of certification-compliant coffee were produced but only 840,000 MTs were sold as such, making the supply nearly four times the demand. But the demand for certified coffee has been growing every year, and as consumers begin to demand certified coffee, more farmers will benefit.
