	abstract = {This article tries to identify the key variables that determine land use patterns and the strategies of households towards tree growing in two upland regions in Central Java. A household{\textquoteright}s access to land and market opportunities appear to be such key variables. Households with little land use their land more intensively with respect to crop, livestock and tree production. So do households with access to market opportunities. Based on this type of diagnostic research more appropriate tree-based designs could be developed to contribute to the solution of land use problems in the uplands of Java.},

Several societies and academies have enrolled his talents.

In this interview, Dr. Okigbo explains how research being carried out at IITA is helping Africa to feed itself.},

	abstract = {A grassroots approach to implementing alley farming is described in this paper. The approach emphasizes the participation and cooperation of Nigerian farm households in farming systems research. Strategies were developed to present the critical concepts of alley farming in a culturally acceptable, sustainable, and self-perpetuating manner. Findings are based on three years of field work with the International Livestock Center of Africa and the International Institute of Tropical Agriculture.},
