Catalysing the monitoring and evaluation of Nationally Determined Contributions through North-South cooperation.

The recent 6th Assessment Report by Intergovernmental Panel on Climate Change has been damning to the world. An overwhelming amount of evidence that Nationally Determined Contributions (NDCs) can contribute to stabilising or reversing the course of impacts of climate change is now common. Given the likely update of NDC measures compounded by their complexities and limited resources, it is imperative to adopt effective Monitoring & Evaluation (M&E) systems to ensure that NDCs achieve their planned objectives. Effective roll-out and M&E of NDCs require full participation from all actors in various countries. However, despite existing evidence that shows the developing countries are the most affected by climate change, the role of their researchers in climate change research is not known. Therefore, the need to investigate the global North-South disparities and develop an agenda for future research about NDCs is imperative. To address this gap, a systematic review was undertaken using appropriate terms in Web of Science, Dimensions and ScienceDirect to identify relevant literature. The analysis of the identified literature led to two main findings. Firstly, most studies about NDCs are conducted by global North research institutes and researchers with very little involvement of those from the global South. Secondly, there is a global paucity of research about M&E of NDCs measures. As a major recommendation, while countries should equitably contribute to rolling out NDC projects, research should play a key role and should be inclusive as possible representing voices from the global North and South.

The potential of solar photovoltaic systems for residential homes in Lagos city of Nigeria.

The development and use of solar photovoltaic (PV) technologies worldwide is considered crucial towards fulfilling an increasing global energy demand and mitigating climate change. However, the potential of a solar PV-system is location specific, influenced by the local solar resource, energy demand and cost among other factors. The main aim of this study is to conduct a detailed assessment of the potential of solar PV-systems in residential buildings in Lagos Metropolitan Area, Nigeria. Nigeria has enormous solar energy potential, it is the most populous country in Africa and occupies a significant place in the development of Africa. Yet, it is a country with one of the lowest per capita electricity consumption in the world - at 149 kWh per capita for a population of about 170 million, about 7% of Brazil's and 3% of South Africa's. To achieve this goal, this study employed the survey of 150 residential buildings in three local government areas (LGAs) in Lagos State, Nigeria to obtain electric load data. HOMER Pro was used to size the PV-systems and to determine the levelized cost of electricity (LCOE). The computed energy results of the study for the base case scenario revealed the PV array, lead acid battery and the converter (inverter) of the PV-systems to be in the following range: 0.3-76 kW; 2 to 176  kWh; and 0.1-13.2 kW respectively. Economic analysis revealed a LCOE of the systems in the range of 0.398 USD/kWh to 0.743 USD/kWh. The use of PV-system generated electricity in the dwellings has potential for an annual reduction of greenhouse gas emissions in the range of 31.24 kgCO2eq to 7456.44 kgCO2eq. Clearly, the use of solar PV systems in residential buildings possesses potentials for enabling Nigeria to attain its climate change mitigation targets indicated in her Nationally Determined Contributions (NDCs).
