Item Review and analysis of vulnerability to rainfall variability and policy responses to agricultural water supply in Nigeria(WFL Publisher Science and Technology, 2016-04) Olayide, O. E.; Tetteh, I. K.; Porter, J. R.; Popoola, L.This paper reviewed and analysed vulnerability to climate change-induced rainfall variability and policy responses to agricultural water supply in Nigeria. The review provides evidence for policy feedbacks as well as priority setting for the post-2015 sustainable development agenda. Nigeria’s vulnerability to climate change variability is due to a number of factors: its geographical characteristics, limited capacity to adapt, dependence on climate-sensitive resources, teeming population, and concentration of Gross Domestic Product (GDP) generating industries in locations that are highly vulnerable to climate change. The poverty level in the country could further worsen climate change adaptation and mitigation strategies. The policy responses were identified and categorized either as climate change sensitive or climatic change specific.Item Trends and Policy Correlates of Agricultural Production and Agricultural Production Sustainability Outcomes in Ghana and Nigeria(Canadian Center of Science and Education, 2015) Olayide, O. E.; Tetteh, I. K.; Popoola, L.This paper analysed policy correlates of agricultural production and agricultural production sustainability outcomes in Ghana and Nigeria. It underscores the influence of political systems and international development agendas as correlates of agricultural production and agricultural production sustainability outcomes. This is to the extent of providing evidence policy on agricultural production and agricultural production sustainability outcomes. Ghana and Nigeria have comparable farming/agricultural system and policy environment. Data used for the analyses spanned five decades. Trends analysis and inferential statistics were employed. The results revealed that policy correlates can contribute to the current discourse in sustainable development agenda and to resolving the dilemma of agricultural policy implementation for sustainable agricultural development, especially in Ghana and Nigeria. The findings reinforce the need for appropriate policies in transforming the agricultural sector while ensuring sustainable development outcomes.Item Differential impacts of rainfall and irrigation on agriculturalproduction in Nigeria: Any lessons for climate-smart agriculture?(elsevier, 2016) Olayide, O. E.; Tettehb, I. K.; Popoola, L.The rain-fed agriculture system is vulnerable to climate change impact. However, such impact may alsovary by aggregate and sub-sectoral levels of agricultural production. The impact of climate change andvariability on agricultural production would engender appropriate policies and practices towards a sus-tainable agricultural production system. We investigated the differential impacts of rainfall and irrigationon agricultural production in Nigeria, and drew lessons for climate-smart agriculture (CSA) in Nigeria.Using time series data that spanned 43 years and econometric analytical technique, we quantified thedifferential impacts of rainfall and irrigation on aggregate production and sub-sectors (all crops, staples,livestock, fisheries and forestry). Irrigation had positive and significant impact on aggregate agriculturalproduction as well as all sub-sectors of agriculture. These findings suggest the need for the minimizationof the impact of climate-induced production risks through CSA which would involve complementarydevelopment of more arable land areas under irrigation in Nigeria. Irrigation would also enhance com-plementary agricultural water management for the development of all the sub-sectors of agriculture,thereby enhancing food security and sustainable agricultural production under prevailing climate changeand variability.Item Assessing the Transition from Survival to Sustainability: Case of Wechiau Community Hippo Sanctuary in Upper West Region of Ghana, West Africa(Canadian Center of Science and Education, 2013) Olayide, O. E.; Popoola, L.; Olaniyan, O.; Dapilah, F.; Abudulai Issahaku, R.Y.In the past 50 years, humans have changed ecosystems more rapidly to meet growing demands for food, fresh water, timber, fibre and fuel. This has resulted in substantial decrease in biodiversity, including the hippopotamus (hippo) population. There are currently about 150,000 hippos left in the world. Their status will change from vulnerable to endangered if threats are not controlled. The threats include destructive exploration and exploitation for human survival through hunting for ivory and meat, habitat loss due to flooding and destruction of hippo lawns along river banks. Sustainable exploration of biodiversity on the other hand ensures a balance in nature through synergistic cooperation in ecosystem services, human well-being as well as the direct and indirect drivers of change. This study assessed the emerging transition from survival to sustainability in the management of community-based biodiversity management in Ghana. Ghana has two hippo populations; one at Bui National Park and the other at the Wechiau Community Hippo Sanctuary (WCHS). The WCHS was established in 1998. It was chosen for in-depth analysis and assessment. The ecosystem assessment framework of interaction between ecosystems and drivers of global change was adopted for the study. The assessment was based on “before” and “now” scenarios to draw inferences for impact of community-based biodiversity management and sustainability. The WCHS provides economic alternatives to converting community-based ecosystems into sustainable economic ventures, including eco-tourism. The number of tourists to WCHS that stood at less than 500 persons in 2002 increased to 2,390 persons in 2011. The test of correlation between the number of local and foreign tourists revealed significant (p<0.001; ρ = 0.926) relationships in the influx of tourists to WCHS. This is evident by the increase in revenue that accrued to the WCHS. It also generated peaceful cohesion and aesthetics of the environment and development of property rights. The WCHS has led to the reduction in poverty and hunger through the generation of incomes, improvement in health through infrastructural provision, and biodiversity sustainability of local species. The case of WCHS demonstrates that biodiversity management founded on good communal relationships cannot only improve the livelihoods of the rural poor but also increase their resilience to face challenges as the people become more economically and socially resilient, and empowered to handle future threats to ecological imbalances.
