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;

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

– Collaboration between farmer groups, local authorities, and support organizations proved essential to maintaining supply, building trust, and ensuring stable market access. – Establishing a sustainable market and fair pricing through formal contracts proved to be the most significant motivator for farmers to actively produce. – Field-based, hands-on, and peer-to-peer training proved highly effective, improving both technical confidence and productivity, with monthly yields rising from 2 to 3.5 tons

𝐃Did you know weaver ants are helpful for pest control? Weaver ants are considered farmers’ friends as they protect crops like cashews from pests. Introducing weaver ants is just one of many techniques used in Agroecological Crop Protection (ACP), which combines the principles of agroecology, Integrated Pest Management (IPM), Organic Agriculture, and regenerative agriculture. This natural solution reduces crop damages, improves yields and nut quality, ends the need to spray chemical pesticides, reduces production costs and increase’s farmers profit margins. Moreover, it maintains the health of farmers and the environment while also improve the resilience of farming systems. Watch this video to learn about weaver ant management techniques and the successful experiences of organic cashew farmers in Preah Vihear province.

Weaver ants (Oecophylla smaragdina, Hymenoptera) have been used for more than 2,000 years for the suppression of insect pests in Asian mango and citrus orchards, thus constituting the oldest known example of biological control in agriculture. Yet, in the Mekong Delta, pockets of smallholder farmers are still conserving weaver ant populations and relying upon these beneficial insects to keep pests at bay, especially in cashew plantations. Weaver ants are found naturally in organic plantations but their benefits are often unknown, as far as the possibility of increasing their population as a way to manage insect pests.

In Xiengkhouang, declining maize yields due to soil depletion combined with rising production costs are pushing smallholder farmers to shift to new crops. Many farmers are turning to banana cultivation. However, banana monoculture is not sustainable and therefore, a more resilient alternative is integrated farming, especially systems that combine bananas, fruit trees, and coffee.

The augmentorium is a netted structure (tent or cage) used to confine fruits that have been infested by fruit flies. It prevents adult fruit flies from escaping while allowing beneficial parasitoids, which destroy the fruit flies, to get in and out. It is both a waste management tool and a biological control. This technical leaflet presents step by step how to use an augmentarium for managing fruit flies in the mango plantations

A technical guide for composting composting animal waste and agricultural by-products. Composting manure with biological products is the process of decomposing animal and plant waste into organic matter that is easier for plants to digest after just a few weeks or months. This process reduces odor, disease germs, helminth eggs, and harmful bacteria.

This policy brief, after reviewing agrarian transition, agricultural public policies, actors and organisations supporting Agroecology in Vietnam, presents a rationale to develop agroecology and gives recommendations on different interventions and approaches that could be leveraged by public authorities and other stakeholders to catalyze and bring to scale a full-fledged agroecological transition in Viet Nam.

Crop-Livestock Integration (CLI) through biomass exchanges between crop and livestock enhances the sustainability of mixed farming systems, improving production, autonomy, efficiency and recycling. By analysing the diversity and recent changes in mixed farms and modelling potential CLI pratices changes, we assess the effect of these changes on farm performance and sustainability in Ðiện Biên District, Northwest Vietnam. CLI enables farms to improve animal feed and environmental performances if pressure on land resources remains minimal. High pressure on pasture land may force pasture-dependent farms to cease animal production despite support for forage development. Agroforestry (fruits and forage) could enhance animal feed and farm performance with high-value products, though still its innovative stage. The results show that local authorities must continue to develop innovative models for the production and conservation of forage and crop residues, while also devising additional strategies to support resource-constrained farms. It suggests exploring new forage production systems and biomass management between farms with a broader district-level vision.
