Climate Variability and Urban Agricultural Activities in Ibadan, Nigeria

Abstract

Two terms that are enjoying increasing overwhelming global literature advocacy and discussion are urban farming and climate change. While there is increasing advocacy towards the relevance of urban agriculture for urban dwellers and how it translates into a mitigation strategy against climate change variability and adaptation to urban poverty, the effect of some urban farming activities and how it serves as a driver to climate change needs to be investigated. In most of the urban periphery where there is availability of a large expanse of land areas, farming activities are usually practised in form of settlement farm, livestock rearing, or plantation agriculture. The study based on quantitative and qualitative data from urban farmers in Ibadan argues that the location of urban farmlands is dependent on climatic factor such as access to land. The study identified that climate variability as reported by the urban farmers has resulted in the increased use of fertilizer for farming by urban farmers, and the main activity that is pro-climate change and variability is bush burning.

“…The results also showed that soil properties decreased from the surface to the subsurface soil layer (Table 1). This is in line with the findings of Adam et al (2019), Hayatu et al (2019), Popoola and Mgbonu (2018), Yakub andMallo (2018), andDikko et al (2010) who reported that soil pH, cation exchange capacity, organic carbon, organic matter, total nitrogen and available phosphorus decreased with soil depth (from surface to subsurface soil layers). Olubanjo and Inaidoh (2017) also reported that slope position and soil depth significantly influenced soil chemical properties such as pH, N, Ca, Mg, K, H and ECEC.…”

“…The results further showed that the available phosphorus, magnesium, exchangeable acidity and cation exchange capacity increased with soil depth. This however contradicts the findings of Adam et al (2019), Hayatu et al (2019), Popoola and Mgbonu, (2018), Yakub andMallo, (2018), andDikko et al (2010) who reported that soil pH, cation exchange capacity, organic carbon, organic matter, total nitrogen and available phosphorus decreased with soil depth (from surface to subsurface soil layers).…”

“…The reflection of the changing climate has been said to be both anthropogenic and nature-driven (Popoola, 2019). Identifying the argument is that many anthropogenic activities such as unplanned urbanization (Coraiola, et al, 2011;Babatola, 2013;Lasisi, et al, 2017), bush burning, deforestation, and over-grazing (Wahab and Popoola, 2019;Popoola, 2019) are all drivers for the changing climate and increased global warming.…”

For example, Coraiola, et al (2011), argued that the rapid and uncontrolled urban development, the introduction of paved surfaces, reduction of green areas and heat emission by vehicles led to an increase in air temperature in urban areas, causing detrimental effects to human health and irreversible environmental problems.…”
