Conservation agriculture

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 …

Risk aversion, impatience, and adoption of conservation agriculture practices among smallholders in Zambia

Sustainable agricultural practices such as conservation agriculture have been promoted in southern Africa for nearly three decades, but their adoption remains low. It is of policy interest to unpack behavioural drivers of adoption to understand why …

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 …

Influence of 9 years of permanent raised beds and contour furrowing on soil health in conservation agriculture based systems in Tigray region, Ethiopia

Conservation agriculture (CA) systems represent a set of three soil management principles: minimarbance, permanent soil cover and crop rotations - whereas the CA-based systems in this study add the bed and furrow tillage techniques as integral …

Agricultural mechanization and reduced tillage: antagonism or synergy?

This paper reviews agricultural mechanization and reduced tillage use in the context of sustainable intensification in developing country agriculture. The scoping review includes selected and contrasting cases - including Zimbabwe (manual systems), …

Complementary practices supporting conservation agriculture in southern Africa. A review

Conservation agriculture (CA) 'the simultaneous application of minimum soil disturbance, crop residue retention, and crop diversification' is a key approach to address declining soil fertility and the adverse effects of climate change in southern …

Conservation agriculture with trees amplifies negative effects of reduced tillage on maize performance in East Africa

Conservation agriculture (CA) is widely promoted in sub-Saharan Africa both in open fields and in agroforestry where the practice is known as 'conservation agriculture with trees' (CAWT). Although advantages and disadvantages of CA are well studied …

Implementation of Permanent Raised Beds Contributes To Increased Crop Yield and Profitability in the Northeastern Tigray Region, Ethiopia

A major problem faced by small-scale farmers in northern Ethiopia is reduced crop yield due to increasing soil degradation resulting from repeated tillage and inadequate agronomic management practices. These practices have left soils and rainfed …

Restoring cropland productivity and profitability in Northern Ethiopian drylands after nine years of resource-conserving agriculture

Long-term in situ soil and water conservation experiments are rare in sub-Saharan Africa, particularly in Eastern Africa. A long-term experiment was conducted (2005-2013) on a Vertisol to quantify the impacts of resource-conserving agriculture (RCA) …

Gender and conservation agriculture in East and Southern Africa: towards a research agenda

It is remarkable that despite wide-ranging, in-depth studies over many years, almost no conservation agriculture (CA) studies consider gender and gender relations as a potential explanatory factor for (low) adoption rates. This is important because …
