“…This result is not surprising as the higher tannin content in cassava leaves than in BH swards (Table 2) probably reduced the methanogen activity, as reported in previous studies [37]. Secondary compounds such as tannins have been reported to either target methanogen activity or disrupt the commensal relationship between methanogens and other microbes such as protozoa populations and fungi [26,38].…”

Novel Technological and Management Options for Accelerating Transformational Changes in Rice and Livestock Systems

Agricultural producers grapple with low farm yields and declining ecosystem services within their landscapes. In several instances, agricultural production systems may be considered largely unsustainable in socioeconomic and ecological (resource conservation and use and impact on nature) terms. Novel technological and management options that can serve as vehicles to promote the provision of multiple benefits, including the improvement of smallholder livelihoods, are needed. We call for a paradigm shift to allow designing and implementing agricultural systems that are not only efficient (serving as a means to promote development based on the concept of creating more goods and services while using fewer resources and creating less waste) but can also be considered synergistic (symbiotic relationship between socio-ecological systems) by simultaneously contributing to major objectives of economic, ecological, and social (equity) improvement of agro-ecosystems. These transformations require strategic approaches that are supported by participatory system-level research, experimentation, and innovation. Using data from several studies, we here provide evidence for technological and management options that could be optimized, promoted, and adopted to enable agricultural systems to be efficient, effective, and, indeed, sustainable. Specifically, we present results from a study conducted in Colombia, which demonstrated that, in rice systems, improved water management practices such as Alternate Wetting and Drying (AWD) reduce methane emissions (~70%). We also show how women can play a key role in AWD adoption. For livestock systems, we present in vitro evidence showing that the use of alternative feed options such as cassava leaves contributes to livestock feed supplementation and could represent a cost-effective approach for reducing enteric methane emissions (22% to 55%). We argue that to design and benefit from sustainable agricultural systems, there is a need for better targeting of interventions that are co-designed, co-evaluated, and co-promoted, with farmers as allies of transformational change (as done in the climate-smart villages), not as recipients of external knowledge. Moreover, for inclusive sustainability that harnesses existing knowledge and influences decision-making processes across scales, there is a need for constant, efficient, effective, and real trans-disciplinary communication and collaboration.

“…Some of the secondary compounds present in A. sativum (thymol, eugenol, carvacrol) and T. chebula (tannins) were implicated in this effect (Chiquette and Benchaar, 2005;Hess et al, 2005).…”

“…Feeding of foliages as well as fruits of several tropical and sub-tropical multipurpose shrubs and trees has been reported to suppress rumen protozoa. The compounds considered to be responsible for the anti-protozoal effect are saponins or saponin-like substances (Hess et al 2006;Pilajun and Wanapat 2011). Moreover, essential oil and some plant secondary compounds have been used as additives to improve rumen fermentation (Kongmun et al 2010;Mapato et al 2010;Wanapat et al 2011).…”

A number of experiments have been conducted to investigate effects of tropical plants containing condensed tannins and/or saponins present in tropical plants and some plant oils on rumen fermentation and ecology in ruminants. Based on both in vitro and in vivo trials, the results revealed important effects on rumen microorganisms and fermentation including methane production. Incorporation and/or supplementation of these plants containing secondary metabolites have potential for improving rumen ecology and subsequently productivity in ruminants.
