Shifting ground : the changing agricultural soils of China and Indonesia /
In this book Peter Lindert evaluates environmental concerns about soil degradation in two very large countries--China and Indonesia--where anecdotal evidence has suggested serious problems. Lindert does what no scholar before him has done: using new archival data sets, he measures changes in soil pr...
