Abstract

Purpose

A variety of biomass plantations are being raised for energy production. This case study is on energy production potential of seasonal oil bearing crops in India. These crops have the advantage of producing oil (liquid fuel) as well as biomass as agro residue (solid fuel). The purpose of the study is to estimate total energy yields of oil bearing crops and compare with other types of energy plantations. Also oil bearing crops bioaccumulate metals and thus phytoremediate soil. This provides scope for waste water irrigation.

Design/methodology/approach

Relevant published papers on energy production by raising oil bearing crops have been analyzed. The effect of waste water irrigation and agronomic practices on increasing productivity is given special attention.

Findings

It is shown that the seasonal oil bearing crops such as castor have a high potential to generate energy and this is comparable to energy produced by many perennial grasses. The energy yields of castor under irrigated condition was 196×103 MJ/ha and this is comparable to the reed canary grass which yields 195×103 MJ/ha. Some of the oil bearing crops are also super accumulators of certain toxic metals.

Research limitations/implications

In this study, only all the accessible papers on the topic could be analyzed.

Practical implications

This case study indicates that raising oil bearing crops such as castor using waste water has many advantages which include high energy yields, utilization of waste water for productive purpose and phytoremediation of soil.

Originality/value

The comparison made between various types of energy crops for their energy generation is an original contribution. Findings of economic and environmental benefits by waste water irrigation are also of value.

Abstract

Purpose

This study examines the effect of digital financial inclusion (DFI) on climate change in African countries, taking into account the moderating effect of income inequality.

Design/methodology/approach

This study employs panel data from 53 African countries between 2004 and 2021 and utilises the random-effects model and two-step generalised method of moments (GMM) to estimate the relationships amongst DFI, income inequality, CO2 emissions and renewable energy consumption (REC).

Findings

Our findings reveal that increased accessibility to automated teller machines (ATMs) leads to a reduction in CO2 emissions and an increase in REC. However, the effect of ATMs on CO2 emissions is stronger for individuals with lower incomes, whereas REC is higher for those with higher incomes. Additionally, mobile cellular subscriptions (MCS) increase both CO2 emissions and REC; however, when income inequality is considered, it results in a reduction in CO2 emissions and an increase in REC. Furthermore, Internet usage reduces CO2 emissions and increases REC in Africa, with income inequality levels further improving its contribution.

Practical implications

ATM accessibility and energy efficiency are means to mitigate carbon dioxide emissions and encourage the adoption of renewable energy sources.

Originality/value

This study is one of the first to explore the effects of income inequality on DFI, CO2 emissions and REC, highlighting its importance in Africa and its potential impact on environmental sustainability.
