          With the increase in intense rainy periods and over-exploitation of land, traditional architecture (here in the Houndé region in Burkina Faso), increasingly
        
        
          expensive to maintain, is being abandoned and replaced by concrete and corrugated iron, much less appropriate for the high temperatures during the dry season

            Fidel Yogo Adiguipiou has devoted
          
        
        
          
            his retirement as a former agricultural
          
        
        
          
            advisor, to the study of sustainable
          
        
        
          
            development, particularly the impacts
          
        
        
          
            of climate change in Burkina Faso, his
          
        
        
          
            country.
          
        
        
          
            Fidel, what triggered your involvement?

          he first thing was in 1985; it rained on
        
        
          9 November 1985. We had never seen
        
        
          rain in November—our rainy season ends
        
        
          on 15 October at the latest. The second
        
        
          event was in January of the following
        
        
          year: for several days there was reddish
        
        
          dust above the country; it was opaque and
        
        
          almost completely veiled the sun. At the
        
        
          time, we attributed the phenomenon to the
        
        
          passage of the Paris-Dakar rally! It is only
        
        
          now that we are able to understand what
        
        
          was brewing.
        
        
          We could have seen these changes coming
        
        
          but we carried on felling our trees as if
        
        
          nothing were happening and the desert
        
        
          continued to advance and now suddenly
        
        
          there has been much more heat and much
        
        
          more rain for three years. Whereas the
        
        
          rainfall we know in this region of Burkina
        
        
          Faso is from 800 to 1200 mm in the rainy
        
        
          season from June to October, it was more
        
        
          than 1600 mm in 2008, 2009 and again
        
        
          in 2010. And the temperature in the dry
        
        
          season is now often over 45°C in the shade!
        
        
          But more precipitation does not mean that
        
        
          the rainy season is longer—the rain is
        
        
          increasingly intense. Precipitation from 15
        
        
          August to 15 September last year was 400
        
        
          to 500 mm—this used to be the total from
        
        
          June to August.
        
        
          
            What is the most visible impact that is the
          
        
        
          
            most tangible for the population?
          
        
        
          Our traditional habitat is threatened!
        
        
          Kassena dwellings are built entirely in sun
        
        
          dried bricks. Even the roofs are built in
        
        
          earth. They are very heavy and can collapse
        
        
          suddenly when it rains too hard. I have to
        
        
          rebuild my house every year, and last year
        
        
          nearly died, crushed with my family. The
        
        
          people of my village try to combine the
        
        
          techniques of the Kassena and the Mossi,
        
        
          who have thatched roofs, but this is difficult
        
        
          in our culture as thatched dwellings are
        
        
          reserved for bachelors and this isn’t very
        
        
          glorious for a family man…
        
        
          The solution would be to use concrete
        
        
          blocks. But this is much too expensive for
        
        
          a Burkina Faso farmer: earth for building
        
        
          is free while concrete blocks represent
        
        
          months and even years of income for
        
        
          a farmer! And as regards sustainable
        
        
          development, the earth is right there while
        
        
          cement and the transport of concrete
        
        
          blocks use energy.
        
        
          It has to be understood that our agriculture
        
        
          is living on borrowed time. I was an advisor
        
        
          before I retired. My job was to accompany
        
        
          farmers in the use of modern farming
        
        
          techniques. In 1976, yields in the region
        
        
          for cereals as a whole were something
        
        
          like 800 to 1200 kg per hectare, with an
        
        
          extendable fertiliser formula. This is used
        
        
          much more now and often accompanied by
        
        
          manure, which is favourable for sustainable
        
        
          development. But we still don’t manage to
        
        
          exceed 1200 kg per hectare. I don’t really
        
        
          know how to explain this but I can tell you
        
        
          that a field under 50 cm of water from
        
        
          August to September will not give you 1200
