  This study attempted to estimate willingness to pay among the communities of Hulu Langat for watershed conservation. Dichotomous choice contingent valuation method was applied to estimate the willingness to pay. Face to face interview survey was conducted to obtain primary data for logit model estimation. The model estimation indicated that bid amount, income, occupation and residential area were the significant determinants influencing the communities’ willingness to pay. Hulu Langat communities were willing to pay RM 10.13 per person monthly and the total benefits from watersheds conservation was about RM 27.7 million per year. The yearly aggregated amount provided ample financial resources for watershed conservation purpose. It was concluded that engagement of Hulu Langat watershed conservation initiatives was feasible for execution.

  In modern agricultural research, crop modelling has become a critical tool which incorporates scientists’ insights into the physiological and ecological processes by conducting crop growth into mathematical equations. The crop simulation models have been shown to be efficient in assessing the relationships between crop yield and environmental factors. They are able to determine the response of crop plants to change in weather. This study compares six different crop simulation models, namely RICEMOD, CERES-Rice, MACROS, RICESYS, SIMRIW and ORYZA series which can be used to evaluate the impacts of climate change on rice production. Comments are then made about the application and usefulness of these models.

  In recent years, climate change has become a more serious issue than any other environmental problem. One of the main concerns is the risk it poses to food production in developing countries, due to heavy reliance on agriculture. This study examined the influence of climate change on net revenue from maize production in northern Nigeria and the role of socioeconomic factors on farm adaptation. The results are intended to inform farmers, researchers and policy makers, on the impact of climate change on net revenue from maize production in the study area. A farm survey of the respondents found that, there was a significant correlation between climate change (temperature and rainfall) and net revenue from maize production. Results of the study revealed that precipitation plays a more important role as a determinant of farm net revenue, as against temperature, particularly during the rainy season. Furthermore, socioeconomic factors were found to have a mix effect on net revenue. In conclusion the study found that climate change affects net revenue from maize production in the area and there is the need to focus attention on the greatest environmental threat of our time, an issue that previous studies have not addressed comprehensively. The policy implications of the results, if carefully evaluated are expected to serve as a framework for developing climate change adaptation and mitigation options in the study area.
