      abstract = {BACKGROUND : During the last 30 years, the physical,  cultural, and socioeconomic environment in which cropping  is carried out has changed in much of Africa. Population  densities and population growth rates have increased;  arable land per capita, soil quality, and tree cover have  declined; input and credit markets have changed; and (2)  argue that better coordination of macro and the relative  importance of non-farm income has risen. African  governments and donors have devoted much time, effort, and  money to identify constraints, to develop new technologies,  and to change the policy environment so that farmers can  better cope with their evolving environment, thus raising  farm output and productivity. As governments implement new  agricultural policies and programs, it is imperative that  they accurately monitor their effect on productivity. Poor  agricultural data and inappropriate analyses can lead to  misallocation of scarce resources and policy formulation  that fails to resolve critical development and productivity  problems.},
