Integrating strip cropping with grass border enhances soil fertility, maize grain, and nutritional yields in Zimbabwean smallholder farming systems

Smallholder maize production in sub-Saharan Africa is constrained by soil fertility decline and erratic rainfall, leading to low dietary diversity. A four-season on-farm study (2018/2019–2021/2022) was conducted with six farmers in Murehwa District, …

Supporting biodiversity-smart smallholder farming in Africa through systems agronomy

We are facing a biodiversity crisis, which is largely driven by the way we produce food. In response, various approaches to ‘biodiversity-smart farming’ have been proposed, sparking debates, especially in sub-Saharan Africa, a region that was largely …

Addressing agricultural labour issues is key to biodiversity-smart farming

There is an urgent need for agricultural development strategies that reconcile agricultural production and biodiversity conservation. This is especially true in the Global South where population growth is rapid and much of the world's remaining …

Forest proximity positively affects natural enemy mediated control of fall armyworm in Southern Africa

The fall armyworm (FAW, Spodoptera frugiperda) is a major crop pest in southern Africa. It threatens the livelihoods and food security of smallholder farmers in the region by negatively impacting maize yield. Although scientific evidence suggests …

Sparing or sharing land? Views from agricultural scientists

Increased agricultural production through both intensification and extensification is a major driver of the current biodiversity crisis. As a response, two contrasting approaches have been advocated; 'land sparing', which minimizes demand for …

More people, more trees: A reversal of deforestation trends in Southern Ethiopia

Despite global commitments to forest restoration, evidence of the pathways through which restoration creates social and ecological benefits remains limited. The objective of this paper is to provide empirical evidence to generate insights on the …

Agriculturally productive yet biodiverse: Human benefits and conservation values along a forest-agriculture gradient in Southern Ethiopia

Context- It remains unclear how agricultural landscapes can best serve multiple purposes such as simultaneously maintaining agricultural productivity and conserving biodiversity. Objectives - Our objective was to assess how important components of …

Agro-ecological options for fall armyworm (Spodoptera frugiperda Smith) management in sub-Saharan Africa: Providing low-cost, smallholder friendly solutions to an invasive pest

Fall armyworm (FAW), a voracious agricultural pest native to North and South America, was first detected on the African continent in 2016 and has subsequently spread throughout the continent and across Asia. It has been predicted that FAW could …

Understanding the factors influencing fall armyworm (Spodoptera frugiperda J.E. Smith) damage in African smallholder maize fields and quantifying its impact on yield. A case study in Eastern Zimbabwe

Fall armyworm (FAW, Spodoptera frugiperda J.E. Smith) is an invasive lepidopteran pest established in most of sub-Saharan Africa since 2016. Although the immediate reaction of governments has been to invest in chemical pesticides, control methods …
