The Green Revolution in Africa

-

Having previously looked at how the management of water and agriculture has changed over time we now turn to how food production itself has changed in attempting to become more sustainable for the future.

Africa's "green revolution" now or never!

A green revolution can be outlined as greatly increasing food production through the use of technology such as high yield and resistant species of crop. This can also be through the use of fertilisers and pesticides. The United Nations 2022 hunger report highlights that the prevalence of undernourishment has remained stable since 2015 but rose from 8% in 2019 to 9.8% in 2021. Now at least 1 in 5 people face hunger in Africa. With severe food insecurity rising and only 8 years left to meet SDG 2 (Zero Hunger), a green revolution appears to be vital in tackling this problem.

Behind Africa's green revolution

One major organisation behind Africa's green revolution is the Alliance for a Green revolution in Africa (AGRA). AGRA was launched in 2006 by the Bill and Melinda Foundation and the Rockefeller Foundation. They have an integrated approach that is African-led and focused on ensuring smallholder farmers can be self-sufficient. One of AGRA's strategies to improve food production involves the use of seeds that are bred for improved yield and higher resilience. Another strategy involves workshops and activities where farmers are taught how to effectively space crops and use fertiliser. These workshops have been successful in areas in Nigeria such as Giwa where yields in 2020 for most farmers were over two times the size of previous years despite using the same area of land. This allows more food to be produced with the same amount of water.

Another organisation behind the green revolution is the Millennium Promise Alliance (MPA). This organisation ran the Millennium Villages Project (MVP) which lasted from 2005-2015 and took place in fifteen locations. The aim was to allow places in sub-Saharan Africa to achieve the 2015 Millennium Development Goals (MDGs). Similar methods AGRA used to improve agricultural production were implemented such as fertilisers and selectively bred seeds for higher yield and resistant crops. The water infrastructure in these villages was improved by constructing springs. This allows more children to have a free school meal which raises attendance. The project achieved a third of its MDG targets despite them being ambitious.

A green solution?

Overall, the green revolution has great potential to meet SDG 2. Projects from AGRA and MPA have provided a good framework for development in Africa to increase food security. These projects can promote self-sufficiency and African-led development. Without the voices of local people, improvements cannot be successfully implemented. However, not all aspects of the green revolution are positive. Some of these challenges and failures will be explored in the next post.

Groundwater and Farming in Africa

The development challenge In 2015 the United Nations member states adopted 17  Sustainable Development Goals  (SDGs). These aimed to promote action in improving conditions for all life while tackling climate change. When looking at water and development in Africa, SDGs 2 (Zero Hunger) and 6 (Clean Water and Sanitation) are critical in improving quality of life. As discussed in the last post water resources are highly variable. Food production per capita rates are also some of the lowest in the world. Africa's current population of 1.4 billion is projected to increase to 4.2 billion by 2100. Therefore, different farming practices and new resources of water are essential to improve agricultural production and resilience to climate change. Figure 1 : The 17 Sustainable Development Goals. Rain-fed and irrigated agriculture Smallholder farmers are vital making up 80% of all African farms and accounting for 90% of the agricultural production in many countries. The vast majority o...

The Importance of Wetlands: Hadejia-Nguru Wetland Case Study

This post looks at the importance of wetlands through a case study example. These environments encompass many issues and challenges within the topic of water and food which makes them perfect to explore. What are wetlands? Wetlands are areas of land that are often inundated with water. This can happen seasonally or periodically in some areas while other areas of wetland can be inundated permanently. Some important African wetland features can include peatlands, rivers, deltas, mangroves, and floodplains . These ecosystems have been argued to be some of the most productive in the world and also at the greatest risk from climate change . Overall, wetlands make up approximately 1,341,500 km2 of the total area in Africa with the largest areas of wetland around the equator.  Figure 1 : Locations of wetlands in Africa by area.  The Hadejia-Nguru Wetlands The Hadejia-Nguru Wetlands (HNWs) are located in the Yobe State, Northern Nigeria, and are part of the Chad Basin. This area is...

Challenges of the Green Revolution

-
Image
Having looked at the green revolution in Africa through a positive lens it is important to examine who is benefiting the most and who may be getting left behind.  Farmers left behind.  Organisations such as the Alliance for a Green Revolution in Africa (AGRA) and Millenium Promise Alliance (MPA) have shown how new seeds have improved crop yields and resistance.  However, the most recent AGRA 2021 report highlights that only 49% of the 11 million farmers directly reached for new technology and infrastructure between 2017-2021 actually adopted the new seed varieties. One major reason for this is that families have been farming for their livelihoods for a long time and have developed cultural practices that are not accounted for when introducing new technology. Another reason for this is that the new seeds tend to be more expensive than the ones previously used. This leads to the improved yield not making up for the cost of the new seeds planted  over smaller areas....
