Upcoming APRNet Seminar on Climate Change Risks next Thursday in Abuja


Join us next Thursday for the first edition of APRNet's Policy Seminar series. The objective of this new series is to provide APRNet members a unique opportunity to disseminate significant policy research to and receive feedback from the relevant audience. The Policy Seminar series is one instrument for achieving APRNet’s strategic mission of "connecting research and policy".

The first in the series will feature Dr. Anthony O. Onoja and Prof. Anthonia I. Achike, who will be presenting their scholarly research on climate change risks and the effects on arable crops in Nigeria. The presentation, titled Economic Analysis of Climate Change Risks and Effects on Arable Crop Production in Nigeria, is an intellectual effort designed to evaluate the effects of climate change on arable crop productivity in Nigeria. This particular work is timely, given the rising climate change effects and risks on farm productivity in virtually every part of the globe.

Date: Thursday, April 10, 2014

Time: 2:00PM - 3:30PM

Venue: IFDC/IFPRI Conference Room No 6/Plot 1413 Ogbagi Street; Off Oro-Ago Crescent, Cadastral Zone II, Garki II, Abuja-Nigeria (Near old CBN building and behind Union Homes)

RSVP: Please email obasibasil22@yahoo.com or info@aprnetworkng.org on or before April 9, 2014 to confirm your attendance. We apologize, but we are unable to provide transportation stipends to attend this event.

Abstract: The growing impacts of climate change have constituted risks to smallholder arable crop farmers’ yield and net revenue, worsening food insecurity and poverty in Nigeria. Hence this study was designed to evaluate the effects of climate change on arable crops’ productivity, in Nigeria. It ranked climate change risks affecting farmers in Nigerian agro-climatic zones and then estimated the influence of climate factors on farm productivity (net revenue variability) in the country. The study relied mainly on institutional (NIMET) and primary data for its analysis. Data were obtained using a set of structured questionnaire administered in a multi-stage, stratified random sampling manner on arable crop farmers producing maize, rice, cassava, yam and cowpeas. Sixty (60) farmers each were randomly selected from 5 states; in each of the five agro-climatic zones in Nigeria giving a total sample size of 300. Data were analyzed using Kendall’s W statistics, Ricardian model and OLS.

It was found that soil nutrients loss (mean rank = 2.12), flood (mean rank = 2.59) and increased temperature (mean rank = 2.50) were the most risky climate change factors in Swampy Forest, Tropical Forest, and Guinea Savannah zones respectively. In the Sudan and Sahel Savannahs, the most risky threat was drought (mean ranks = 1.53 & 1.72 respectively). Rainfall and temperature variations, planting materials costs, household size and labour cost exerted statistically significant effects on level of gross margins. Their elasticities were 1.199 (p <0.01), 8.219 (p <0.01), 0.108 (p < 0.05), 0.097(p <0.01) and 0.124 (p <0.05) respectively. Their elasticities were all statistically significant at p < 0.01.

Based on the findings, it was recommended that government and stakeholders in Nigerian agricultural policy making should put in place policies that will help resettle displaced farmers, promote investment on irrigation, provide weather stations to farmers and early warning information, build capacity of crop farmers to respond to effects of climate change, invest in research to develop climate resilient crop seeds/seedlings.
