Benin is one of the poorest countries in the world. Sustainable land use is therefore even more important so that, for example, soil erosion does not lead to further poverty. Therefore the main question in Gandonou’s doctoral research was to what extent would agriculture on fragile slopes become more sustainable if the farmers were given more possibilities for selling their products and acquiring production resources. The study is based on empirical data collected in 1998 and 1999 in Boukombé in the northwest of Benin.
The results show that in a remote area such as Boukombé, the effects of a closer market on erosion control are marginal. This is partly because many efforts to conserve the soil are already being undertaken, and partly because incomes of farmers in this area remain very low, even if the market is nearby. Gandonou’s research has made it clear that reducing the distance to the market has slight, but positive, effects on the yields of grains and therefore on the attractiveness of soil conservation. Artificial fertilisers plays a key role in this: these can only be used successfully if the subsoil has not been eroded too much and the water runoff is not too strong. This means that a farmer who wants to use artificial fertilisers will also have to take soil conservation measures. To date this study is the clearest example of how soil conservation contributes to an increased yield.
A more accessible market also provides households with more opportunities to grow other, more commercial crops or to undertake other profitable activities. Investments in an improved infrastructure can therefore contribute to improved agricultural returns, and these higher returns induce farmers to invest more in the sustainable use of slopes.
The Ph.D. thesis, ’Sustainable Land Use and Distance to the Market. Micro Evidence from Northern Benin’ was written by Esaïe Gandonou at the Vrije Universiteit Amsterdam and is part of the programme The Agricultural Transition to Sustainable Tropical Land Use financed by the NWO Stimulation Programme Environment & Economy.
Esaïe Gandonou’s research was funded by NWO.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
