Sustainable Maize production: The potential of Conservation Agriculture

This policy brief presents the potential of conservation agriculture to overcome soil fertility depletion and land degradation problems due substantially to conventional maize production. It promotes the benefits of conservation agriculture as well as key priorities and options for policy;

Multicriteria Assessment of Implemented Conservation Agriculture Cropping Systems Across Farmers’ Plots in Northwestern Cambodia

In Cambodia’s maize crop, conservation agriculture delivers clear gains in soil health, an improved yield resilience and emerging economic benefits over a short (2-year) implementation span. Soil health, as measured using the Biofunctool, emerges as a valuable sustainability indicator that warrants further promotion. Regardless of the above, productivity and profitability benefits under CA are not immediate, and several prominent adoption challenges exist. With the right policy support, tailored agronomic research, technical innovations (e.g., adaptive machinery) and farmer training, CA could be scaled up to address Cambodia’s dual crises of land degradation and climate vulnerability

How to Overcome Soil Degradation : example of the Nonglae Village, Lao PDR

Soil degradation, often caused by poor agricultural practices, can lead to a decline in crop yields. Traditionally, when yields dropped, farmers would leave fields fallow for at least three years to restore fertility. However, with less viable land available, fallow periods have shortened, making it harder to maintain yields and ensure sustainable profits.
In Nonglae Village (Nonghet District, Xiengkhouang Province, Lao PDR), local farmers apply indigenous knowledge to overcome this challenge. One example is regenerating soil fertility with cattle through block rotation techniques. This approach can help restore the land while sustaining agricultural productivity over the long term.
