Peatlands management for sustainable use on the integration of maize and cattle in a circular agriculture system in West Kalimantan, Indonesia. Heliyon 2024; 10:e31259. [PMID: 38813176 PMCID: PMC11133880 DOI: 10.1016/j.heliyon.2024.e31259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Revised: 05/13/2024] [Accepted: 05/14/2024] [Indexed: 05/31/2024] Open
Abstract
Management of peatlands with an integrated system of maize and cattle is an alternative to circular agriculture in peatland areas that can increase economic growth in rural areas which is environmentally friendly and sustainable (green economy). This study aims to obtain a circular agriculture model with zero waste management based on the integration of maize and cattle which is environmentally friendly and sustainable in peatland areas, in addition to increasing the added value and farmers' income. This circular agriculture model utilizes site-specific technological innovations and local resources that can restore sustainability in the peatland. The analysis methods used were before-and-after study analysis, baseline surveys, field trials using an experimental design and analysis of variance, financial analysis, and institutional engineering. To achieve this goal, two sub-models were implemented, namely a rural agro-industrial approach based on local agricultural resources by managing appropriate site-specific technological innovations (on-farm) and a local human resource approach through rural institutional engineering, that is farmers' institutional initiation, development, empowerment, and institutional strengthening of agribusiness (off-farm). The results showed that the circular rural agricultural management model on integrating maize and cattle as a benchmark could increase farmers' income in the peatland areas by more than 208 % from IDR 4,760,000 to IDR 14,600,000 per month. The management of peatlands through circular agriculture can improve quality products and add value to the utilization of waste such as animal feed products (silage), organic fertilizers, and biourine. This rural circular agriculture model is carried out by social engineering, initiation, and strengthening of rural agribusiness institutions that are environmentally friendly so that they can be sustainable.

Chao K. Family farming in climate change: Strategies for resilient and sustainable food systems. Heliyon 2024; 10:e28599. [PMID: 38571580 PMCID: PMC10988049 DOI: 10.1016/j.heliyon.2024.e28599] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 03/15/2024] [Accepted: 03/21/2024] [Indexed: 04/05/2024] Open
Abstract
Family farming plays a pivotal role in ensuring household food security and bolstering the resilience of food systems against climate change. Traditional agricultural practices are evolving into context-specific, climate-resilient systems such as family farming, homestead gardening, and urban agriculture. This study examines the ways in which family farming can foster climate-resilient food systems amidst climate vulnerabilities. A systematic literature review spanning the past 22 years was undertaken to develop a conceptual framework. From this review, 37 pertinent documents were identified, leading to the creation of a context-specific, climate-resilient food system framework. The research posits that family farming facilitates easy access to food and nutrition by capitalizing on family-sourced land, labor, and capital, and by securing access to technology and markets. Each facet of family farming is intricately linked with sustainability principles. Local adaptation strategies employed by climate-vulnerable households can diminish their vulnerability and augment their adaptive, absorptive, and transformative capacities, enabling them to establish a climate-resilient food system. The research further reveals that farming families employ a myriad of strategies to fortify their food systems. These include crop diversification, adjusting planting times, cultivating high-value crops and fish, planting fruit trees, rearing poultry and livestock, and leveraging their land, labor, and resources-including their homesteads-to access food and nutrition. This study endorses the climate-resilient family farming framework and offers multiple metrics for assessing the resilience of family farming in developing countries.

Abstract
Besides a vital sector of the economy, agriculture is a primary source of greenhouse gas (GHG) emissions. The present paper investigates the impact of carbon tax policy on Vietnamese agriculture by focusing on multi-product systems such as rice, livestock, and aquaculture, traditionally called the Vuon (Garden)-Ao (Pond)-Chuong (livestock pen) system (VAC). In it, farmers use garden, pond, and pen by-products as fertilizer and feed. We use shadow prices and Morishima substitution elasticities as greenhouse gas emissions indicators, estimated with directional output distance function. Farmers in the Mekong Delta region are found to be technologically less efficient than in other regions of Vietnam, though the shadow prices of GHG emissions are lower there too. This indicates that farmers in the Mekong Delta, generally concentrating either on livestock or aquaculture, have greater potential for reducing GHG emissions by way of improvements in technical efficiency than do those in other regions. However, Morishima elasticity estimates show that policy impacts diminish more quickly in the Mekong than elswhere. We suggest the Vietnamese government encourage Mekong Delta farmers to employ technologically more efficient methods or shift to more balanced farming to reduce the shadow price of GHG emissions, encouraging more efficient emissions reduction.

Understanding the impacts of the COVID-19 pandemic on sustainable agri-food system and agroecosystem decarbonization nexus: A review. JOURNAL OF CLEANER PRODUCTION 2021; 318:128451. [PMID: 36570877 PMCID: PMC9759292 DOI: 10.1016/j.jclepro.2021.128451] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/28/2021] [Revised: 07/16/2021] [Accepted: 07/25/2021] [Indexed: 05/25/2023]
Abstract
The existing finite natural resources have witnessed unsustainable usage in the past few years, especially for food production, with accompanying environmental devastation and ecosystem damage. Regrettably, the global population and consumption demands are increasing ceaselessly, leading to the need for more resources for food production, which could potentially aggravate the sustainability and ecosystem degradation issues, while stimulating drastic climate change. Meanwhile, the unexpected emergence of the COVID-19 pandemic and some implemented measures to combat its spread disrupted agricultural activities and the food supply chain, which also led to a reduction in ecosystem carbonization. This study sets out to explore policy framework and selected feasible actions that are being adopted during the COVID-19 pandemic, which could potentially reduce the emissions even after the pandemic to promote a resilient and sustainable agri-food system. In this study, we reviewed 27 articles that focus on the current state of the agri-food system in light of the COVID-19 pandemic and its impact on the decarbonization of the agroecosystem. This review has taken the form of a systematic methodology in analyzing the adoption and implementation of various measures to mitigate the spread of COVID-19 on the impact of the agri-food system and reduction in ecosystem degradation. Up to 0.3 Mt of CO2 reduction from the agri-food system alone was reportedly achieved during the first 6 months of the pandemic in 23 European countries. The various adopted measures indicate that the circular economy approach is a panacea to achieve the needed sustainability in the agri-food system. Also, it dictates a need for a paradigm change towards improvement on localized food production that promotes sustainable production and consumption.

ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2021; 272:116180. [PMID: 33445152 DOI: 10.1016/j.envpol.2020.116180] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 11/13/2020] [Accepted: 11/26/2020] [Indexed: 06/12/2023]
Abstract
Although liquid products derived from the pyrolysis of biomass are promising for the production of petroleum-like hydrocarbon fuels, the catalytic burden of hydrodeoxygenation must be reduced to achieve feasible upgrading processes. Herein, mild hydrotreating of an acid-rich biomass pyrolysis oil (bio-oil) with an unusually high total acid number (588 mg KOH/g bio-oil) was performed to stabilize the low-quality bio-oil. Ru-added TiO2-supported transition metal catalysts stabilized the bio-oil by reducing its acidity more compared to what could be achieved by Ru-free catalysts; this process also leads to lower loss of organic compounds compared to when using a Ru/TiO2 catalyst. Based on the performance of transition metal catalysts, including Ni, Co, and Cu, supported on TiO2, tungstate-zirconia, or SiO2, supported bimetallic catalysts were prepared by adding Ru to the TiO2-supported metal catalysts. The bimetallic catalysts Ru/Ni/TiO2 and Ru/Co/TiO2 exhibited good decarboxylation activity for the removal of carboxylic acids and a higher yield of organic compounds compared to that provided by Ru, which can be deemed appropriate for feedstocks when hydrodeoxygenation needs to suppress the loss of organic reactants. Using these catalysts, the carboxylic acid concentration was reduced to 319-323 mg KOH/g bio-oil with organic yields of 62-63 wt% at reaction temperatures 150-170 °C lower than the temperature required for direct conversion of carboxylic acids to alcohols or deoxygenates. The improved catalytic hydrotreating activity of Ru-added transition metals can be attributed to the high acid site densities of these catalysts along with their improved hydrogenation activities.
