Weaver Ant: a natural ecological practice to protect cashew nut plantations

Did 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 ant, a natural ecological practice to protect cashew nut plantations

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.

Reducing Risks and Diversifying Income with Banana – Coffee – Legumes Multi-cropping

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.

Strengthening multi-stakeholder agroecology platforms in Vietnam: A landscape analysis

Using multi-stakeholder platforms offers a promising approach for sharing agricultural innovation, reducing transaction costs, and catalyzing development through stimulating stakeholder engagement in the innovation process to accelerate food systems transformation. Agriculture-related multi-stakeholder platforms (AMSPs) are major players to intervention strategies of agricultural development programs. However, AMSPs face multiple challenges that limit and negatively impact their functions. This study aims to map the AMSP landscape, examine their operational activities, and provide recommendations for strengthening private- and public-sector engagement to support long-term agricultural sustainability in Vietnam. The study used a three-step qualitative research approach to identify AMSPs and subsequently collected secondary and primary data. Results reveal three types of AMSPs classified from 35 identified platforms: (i) development organization-led, (ii) civil society organization (CSO)-led, and (iii) government organization-led platforms. Their main characteristics were then investigated according to the four basic dimensions of organizational theory: structural, contextual, operational, and relational aspects. Next, the study analyzed the influence of each AMSP type on agricultural policies and practices, including those integrating agroecological approaches. The study then examined each AMSP’s achievements and challenges related to AMSP impact and sustainability, together with the constraints related to private- and public-sector engagement, and incentives and investment in agroecological transition. This landscape analysis has identified various mechanisms and possibilities for the Agroecological TRANSITIONS Program — and other related sustainable approach projects — to engage with these AMSPs. This collaboration will stimulate a process for the co-design and co-creation of innovative incentive mechanisms to leverage investment, support the use of holistic traceability tools, and scale-out agroecological practices in rice value chains in Vietnam.

Heterogeneous mitigation effects of adaptation initiatives on grain yield losses from extreme temperatures in China: implications for grain resilience and food security

Introduction: The increasing frequency of extreme weather events has posed significant challenges to global food security. While it is well established that such events can reduce food production, the specific effects of different types of extreme weather on food security, as well as the heterogeneous mitigation strategies available, remain inadequately understood. Methods: This paper systematically analyzes the impacts of extreme high and low temperature events on maize yields using panel data from major maize-producing regions in China from 2000 to 2023, highlighting the potential threats climate extremes pose to food security. Results and discussion: The findings reveal that: (1) extreme high temperatures significantly suppress maize yields, with the number of extreme heat days showing a consistent negative effect nationwide and across regional and growth-stage subsamples, particularly pronounced in northern summer maize-producing areas, indicating heat stress as a key constraint on stable grain production and supply; (2) the effects of extreme low temperatures exhibit clear regional heterogeneity, with southern spring-sown maize more vulnerable to late frosts during seedling and nodulation stages, resulting in greater yield losses, whereas in northern regions, low temperatures mostly occur before sowing and have a limited impact; (3) the adverse effects of extreme temperatures have intensified over time, with extreme heat impacts worsening in recent years—reflecting cumulative climate risks and agricultural system vulnerability—while the negative impacts of low temperatures have somewhat diminished since 2010, indicating improved farmer adaptation; (4) agricultural insurance and protected agriculture have significantly mitigated the impacts of extreme low temperatures on maize yields, demonstrating their effectiveness in cold climates, but have yet to provide significant buffering against yield losses from extreme heat, suggesting opportunities to optimize existing insurance mechanisms and protective agricultural technologies. These findings contribute to a deeper understanding of climate adaptation strategies and support the achievement of SDGs 2 (Zero Hunger) and 13 (Climate Action) through enhancing resilience in the agri-food system.

Strengthening agroecological resilience through commons‑based seed governance in the Philippines

The Filipino agricultural sector is exposed to multiple climatic, economic, and social risks that will likely intensify in the near future. Building agroecological resilience has been proposed to protect small-scale farmers’ livelihoods and improve food security in the context of (unexpected) shocks and disruptions, and slow system changes such as climate change. This paper argues that commons-based seed production, based on collective management and ownership of seeds and varieties, can play a central role in building resilience capacities in smallholder communities. I explore this by applying an indicator-based framework to assess the contribution of the Filipino farmer network Magsasaka at Siyentipiko para sa Pag-unlad ng Agrikultura (MASIPAG) to agroecological resilience. I find that the networks’ commons-based seed governance builds agroecological resilience in various ways. By equipping small-scale farmers with the tools to regain control over seed production and breeding, they become stewards of an actively evolving collection of varieties. The in situ maintenance and development of traditional, open-pollinated varieties and a network of diversified trial and backup farms build up buffering capacities and foster agrobiodiversity and local adaptation. A focus on regionally available natural resources reduces vulnerabilities to external factors. Adaptive capacities are strengthened through a high degree of flexibility and responsiveness achieved by self-organization and polycentric organizational structures. Broad participation, shared learning and spaces for experimentation support the development of farmers’ capacities to respond to diverse challenges. Commons-based approaches to seed governance can thus strengthen agroecological resilience and long-term food security in smallholder agricultural systems.

Socioecological analysis of smallholder farming systems in the Philippines: identifying multi-scalar pathways and barriers to resilience

Climate change poses serious threats to agriculture. The Philippines is one of the foremost countries impacted by climate change, with extensive coastlines, high population density and heavy dependence on agriculture. Many smallholders are struggling to cope with intensified typhoons, changing rain patterns, floods, droughts, as well as temperature and sea-level rise. As a primary staple crop embedded in the socioecological fabric of the Philippines, rice systems are of particular significance to resilience building efforts. This dissertation engages in a socioecological analysis of smallholder farming systems within the Philippine rice sector, with the broader aim to identify multi-scalar pathways and barriers to building climate resilience. Drawing on fieldwork conducted between August-December 2016, this dissertation shares the results of a comparative assessment of organic and conventional rice systems located in Negros Occidental Province, an institutional analysis of the organic transition currently underway in the Philippines, and an exploration of a grassroots farmer-led network and their polycentric food sovereignty development approach. Primary data was collected via surveys, key informant interviews, focus group discussions, farmer interviews, and participant observation. My findings suggest that participating organic rice systems are more climate resilient than their conventional counterparts. Despite increased institutional support for organic agriculture, institutional arrangements remain largely oriented toward promoting Green Revolution technologies; obstructing the speed and scale of organic transition and limiting smallholder capacities for building resilience. To overcome adverse socioecological conditions, smallholders have organized into a polycentric network to implement food sovereignty initiatives that increase farmer control over agricultural resources. This bottom-up and multi-scalar development approach has helped smallholders across the Philippines transition to diversified organic systems, as well as enhanced local capacities for resilience building. The evidence presented here suggests that enhancing smallholder resilience in the Philippines requires improving the socioecological conditions for farmers to engage in adaptation and mitigation strategies, as well as community development efforts to reduce their vulnerabilities. To this end, agricultural policy, development agencies, and researchers must work towards capacity building alongside farmers to regenerate agrobiodiversity and locally available resources, facilitate social learning and collective action, as well as address the root causes of their political economic marginalization.
