The analysis integrated a wide range of data and information from spatial databases, administrative statistics, assessment reports and expert knowledge of the particular farming system characteristics, drivers and trends, constraints and development opportunities. The skill of pattern recognition is essential for identifying common mixes of system livelihoods. The farming system is shaped by access to agricultural resources (a basic indicator is length of growing period) and access to agricultural services (a basic indicator is travel time to the nearest market town), and these factors underpinned the mapping and characterization. The management and development of farming systems depend on the strategies of farm households for escape from poverty or improvement of farm incomes. The multidisciplinary analysis teams who identified the farming system constraints and opportunities, and the household strategies, subsequently wrote the relevant farming system chapters.","PeriodicalId":133556,"journal":{"name":"Farming Systems and Food Security in Africa","volume":"152 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133959736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
