    Monetization of forest's service functions for sustainable forest management
    (2001) Ajewole, O.; Popoola, L.
    This paper examined the concept of monetization and its importance in valuation of the forest's social and environmental service functions, vis-a.-vis its sustainable management. Various monetization techniques are highlighted and discussed. Some of these include surrogate price and replacement costs or costs avoided, value of production increases, opportunity costs, travel costs, hedonic pricing and contingent valuation method. (CVM). The use of CVM is canvassed for, because of its highly flexible framework for the valuation of virtually all social and environmental benefits. It can also be easily adapted in developing and less developed countries, where inadequacy of data on socio-economic and environmental characteristics make the use of most other valuation techniques problematic. Keen interest in monetization of forest's non- market benefits, will ensure "holistic approach" to conservation of our natural environmental resources.

    Public perceptions of urban forests in Ibadan, Nigeria: Implications for environmental conservation
    (Department of Forest Resources Management , University of Ibadan, 2001) Popoola, L.; Ajewole, O.
    This work examines the public perceptions of urban forests in Ibadan vis- a-vis environmental conservation. It covers the five Local Government Areas (LGAs): lbadan North, Ibadan North West, Ibadan South, Ibadan South-West, and Ibadan South-East. Data for the study was obtained from a stratified random sampling of 370 respondents through structured questionnaire-based interviews. The results showed that 99 per cent of the respondents are aware of, and believe that these urban forests serve some purpose in meeting the socioeconomic and physiological needs of the urban populace. Moreover 94 per cent expressed their support for continued preservation of these forests. Of this total, 38 per cent, 36 per cent and 26 per cent respectively, based their support on the fact that these forests can: protect the environment, supply physical needs and be used for recreation. The chi-square test of independence at P = 0.05 revealed that the public perceptions of these forests are dependent on the respondents' residence proximity to at least one of these forest reserves (P > 0.05). Public perceptions may be capitalized upon by governments and other change agencies for the sustainable management of the remnants of Ibadan urban forests.

    Willingness to pay for rehabilitation of Ibadan urban environment through reforestation projects
    (Department of Forest Resources Management , University of Ibadan, 2002) Popoola, L.; Ajewole, O.
    This study was carried out to determine the estimated value of the environmental service functions of the forests of the Ibadan metropolis. It employed the payment card format -Contingent Valuation approach - to elicit willingness to pay (WTP) for environmental rehabilitation of the Ibadan metropolis through reforestation projects, and to investigate the extent to which socio-economic factors influence the WTP. Data were obtained from a multi-stage randomly sampled 370 residents within the five local government areas of the metropolis. The results show that 77% of the respondents were willing to pay various amounts ranging from N50-N500 monthly, NlOO being the modal value, having recorded a 52% response. The mean monthly WP value is N161, resulting in an aggregate estimated value of Ibadan urban forests’ environmental service functions, ranging between N185 468 586 and N240 868 294 (US$1 = NlOO). The reduced model of the double log regression equation revealed the respondents’ employment status and proximity to the urban forest reserves as the only socio-economic variables that significantly influenced WTP. The differences in the mean WTP values within each independent socio-economic variable were not significant (p > 0.05). The results of this study show that there is a need for social valuation of forestry and non-forestry projects that have to do with conversion of forest lands, as a panacea for uncontrolled deforestation.
