Valorization of Caesalpinia coriaria Fruit Waste to Enhance the Ruminal Mitigation of Greenhouse Gases Production

La editorial tiene los derechos de autor y le solicito a hacer visibles la fecha técnica del artículo.The use of fruits waste from tanniniferous trees represents a new technology that aims to solve or mitigate greenhouse gases emission, and to increase the production of food of animal origin in an ecofriendly manner. This study aims to evaluate the production of methane and carbon dioxide, degradability by in vitro ruminal fermentation in goats diet supplemented with nuts (Caesalpinia coriaria Jacq. Willd.) for adoption by livestock farmers. Condensed tannins (CT) of C. coriaria inclusion rates were 0 (CT0 or control, no CT), 1.5 (CT1.5), 3.0 (CT3), 4.5 (CT4.5) and 6.0% (CT6) of the total mixed ration. All CT treatments reduced (linear, quadratic and cubic; P = 0.001) CH4, CO2 and H2 gases, and had some increasing effect on total biogas production. However, CT3 reduced greenhouse gases and had the highest biogas production. Addition of tannins from cascalote fruit waste (C. coriaria Jacq. Willd.) to goats diet at CT3 level reduced methane production, improved fermentation and ruminal degradability in vitro and has potential to be used as ecofriendly feed or feed additive

Sustainable agriculture options for production, greenhouse gasses andpollution alleviation, and nutrient recycling in emerging and transitional nations - An overview

Previous and current agricultural practices have contributed to environmental pollution, which is further affecting food security, human health, and climate. Yet, agriculture cannot be eliminated, because, of its promising role in ending hunger, reducing poverty, improving nutrition, and achieving food security in low-middle income countries. Hence, there is a need for shift from ‘unclean’ practices to sustainable practices. Similarly, differences in pollution, among nations call for regional changes or intervention in agri-food practices to reduce global pollution. These practices are essential for African and Asian countries. Of the many methods proposed in this review, localized technology improvement and globalized sustainable intensification are of high impact models having the potential of mitigating greenhouse gases up to an extent of 30%. Various methods of achieving these measures include, but not limited to, the shift in management systems of crop and livestock production, encouraging agriculture and veterinary practices with less environmental impact and high adaptation, enabling nutrient recycling or recovery, resource-use efficiency, mitigation of nitrous oxide and methane from soil, implementation of integrated farming system and insect farming. Government agencies along with agri-food producers, processors, and farmers must be ready to change their current agricultural practices by adopting new methods. The review conclude that the sustainable agricultural production is possible through the use of low-priced local resources that are capable of increasing soil carbon storage, thus combating the pollution in countries with a transition economy
