There has been a dramatic decline in cocoyam production in Nigeria in recent years due to climate related stressors. We investigated the nature and extent of these impacts and the resilience building strategies used by cocoyam farmers in Nigeria. Data were collected from the farmers in 2010 and 2017 and from FAO statistical database. Results show a yield decline from 8mt/ha in 2005 to 4mt/ha in 2016, due to acid rain, causing bleaching of cocoyam leaves, die back, smaller tubers, early decay of the tubers and decline in the quality and taste of the tubers.

Although, climate change produces a wide range of effects, including output, institution, conflict, investment and etc., there is little knowledge on whether adapting to climate change could produce effects beyond the level of income to include other non-economic channels.

This paper revisits the role of natural resource rent in explaining and regulating CO2 emissions in Sub-Saharan Africa (SSA). Three variants of CO2 emissions are considered: territorial CO2 emissions, consumption-based CO2 emissions, and CO2 emission intensity. Panel-corrected standard error and panel autoregressive distributed lag estimation methods were applied.

Abstract

Most of the empirical literature assessing the impacts of climate change on agriculture has modeled crop yields as a function of the levels or deviations in the growing-period rainfall. However, an aspect that has received little attention in the empirical literature relates to the relationship between the timing of monsoon rains and crop yields. Using a pan-India district-level panel dataset for 50 years, this article investigates two interrelated issues critical to understanding the impacts of weather-induced agricultural risks and their management.

We evaluate the impact of ozone pollution on wheat yields in India and its economic consequences for producers, consumers, and the government. Using an ozone flux–based risk assessment, we find that ambient ozone levels led to a 14.18% average reduction in wheat yields from 2008 to 2012. Irrigated wheat was particularly susceptible to ozone-induced losses, highlighting a potential threat to climate-change adaptation through irrigation expansion. Employing an economic model, we analyze the effects of a "pollution-free" scenario on various factors.
