A major argument put forward in favour of individualised land rights in sub-Saharan Africa is that farmlands held under exclusive and secure rights are more productive than farmlands held under other public or customary forms of tenure. If true, this argument implies that reforms to individualise...

Long term use of Maresha plow, a conventional plow pulled by oxen, has resulted in the formation of a restrictive layer thereby limiting water movement and aeration as well as root zone penetration in the soil profile. Several studies have shown that improved tillage practices can positively affe...
