i. Completed

Ph.D. Students Supervised and Title of Thesis

(a) Soil classification for maize production in the savanna belt of Oyo State.
(b) Comparative Analysis of Soil properties under mechanised and non- mechanised farms.
(c) The impact of riverbank control strategies on agriculture in Rivers State of Nigeria.
(d) Variation of soil properties in Ibadan Metropolis.

Studies carried out under this category investigated the impact of land uses in rural and urban areas such as arable farming, land clearing methods; grazing and residential land uses on the soils. The studies among others identified the important soil parameters influencing the yield of maize and rate the soils of the savanna ecological zone of south-western Nigeria for maize production. In addition, the studies established the crop growth parameters that have indicator significance value in judging soil fertility and estimating crop yield. Other studies in this category established the conservation measures that would be needed to alleviate the fertility and erosion limitations of soils in both the humid and semi-arid zones of Nigeria. The Ibadan metropolis soil study established the basic differences between the soils of rural and urban parts of the metropolis and compared the levels of urban soil contamination of the metropolis with those of other cities in the world.

Environmental Issues

A. The social impact of deforestation in Nigeria: A case study of Olokemeji-Eruwa area of Oyo state.
b Rural energy consumption pattern and deforestation in Nigeria. c. Conservation status of flora and fauna within the Bobo Plains of the Federal Capital Territory, Abuja.
d. The use and management of forest resources in south-western Nigeria: Historical and gender perspectives.

Researches carried out under this category focussed mainly on the use and mis-use of forest resources of south-western Nigeria from the pre-colonial period to the present time. The studies highlighted the unsustainable use of the forest resources introduced during the colonial period and perfected during the post-colonial era. The studies suggested that sustainable forest resource management could only be achieved if there is a shift from forest protection introduced during the colonial period to a people oriented forest management strategy that will ensure food security and conserve the forest biodiversity.

Land-use and soil contamination in Ibadan Metropolis

The study is conceptualised against the backdrop that one of the major effects of human activities in the urban environment is the concentration of various substances in the soil. Having completed the first phase of the study, the second phase seeks to classify the soils of Ibadan metropolis and establish the relationships between land-use types and levels of contamination in the city.

(a) Farmers’ perceptions of soil organic matter in south-western Nigeria.

The study is aimed at examining the role of indigenous nutrient conservation on crops yield in south-western Nigeria. elucidating rural farmers’ perceptions of soil organic matter and other related soil management practices in Ijaye area of south-western Nigeria. It is a farm survey involving more than 100 households in about 20 villages located in the Akinyele LGA of Oyo state. It is hoped that the outcome of the survey will elucidate rural farmers’ perceptions of soil organic matter and other related soil management practices in the southern humid part of Nigeria.
