Conservation agriculture

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 …

Where to target conservation agriculture for African smallholders? How to overcome challenges associated with its implementation? Experience from Eastern and Southern Africa

Since the paper by Giller et al. (2009), the debate surrounding the suitability of conservation agriculture (CA) for African smallholders has remained polarized between proponents and opponents. The debate also gave rise to a few studies that …

Conservation agriculture in African mixed crop-livestock systems: Expanding the niche

Competition for crop residues between livestock feeding and soil mulching is a major cause of the low and slow adoption of conservation agriculture (CA) in sub-Saharan Africa. Retaining crop residues in the field is not only a prerequisite for CA but …
