  • 3.1 The area of study
    
  • 3.1.1 Localisation
    
  • 3.1.2. Landscape, soil and vegetation
    
  • 3.1.3. Climate and Hydrology
    
  • 3.1.4. Population and Economic Activities
    
    • The study area is made up of three counties (Sedome, Esse-Godjin and Tokpli). According to the Togo Population and Housing Census Report in 2010, the total population of the three counties was estimated at about 34918 with 10803 in Sedome, 9261 in Esse-Godjin and 14854 in Tokpli. The majority of the population is located in the River floodplains. Agriculture is the most important activity being carried out in the area with a majority of the people living practising subsistence farming.
      
    • The fertile soils coupled with the abundant rainfall per year ensure ample yields of food crops. The main crops grown in the area include maize, cassava, sugarcane, beans, groundnut, palm trees and some vegetables.
      
    • The people in the targeted area also keep animals such as goats, cattle, pigs and chicken. Other activities in the targeted area include trading, fishing, palm oil production etc.

    • This part describes data collection processes as well as data analysis methods.
      
    • 
      
  • 3.3.1. Primary Data Collection
    
    • Field work plays a very important role in collecting primary data. By applying simple random sampling technique, information were collected through questionnaire-based interviews at household levels and personal observation. The questionnaires are designed based on selected indicators developed under Turner et al (2003) vulnerability framework "Table 2". One question for every indicator under each factor is displayed "Annexe 8".
