“…As a landlocked country, consumption of fish and seafood is very limited in Rwanda, contributing to < 3% of daily (total) protein intake [ 51 ]. Moreover, similar to other LMICs, animal-based proteins are produced from dual-purpose livestock in Rwanda, where eggs and milk are the co-products of meat-producing ruminants (beef, goat, and sheep) and non-ruminant (poultry) livestock [ 52 ].…”

Background The global population is increasingly aging, imposing a substantial burden on social and healthcare systems as aging is associated with gradual muscle wasting and functional decline. Consumption of protein-rich foods, such as livestock-based meat, providing high-quality proteins can prevent muscle wasting and related functional decline in older adults. However, there is a lack of data on the older adults’ perceptions about meat consumption, particularly in Sub-Saharan Africa. Objective To explore the perceptions about dietary meat consumption among older adults in Gasabo district, Kigali, Rwanda. Methods We conducted a descriptive qualitative study, using focus group discussions. A total of eight FGDs, lasting between 55 and 80 min, were conducted with gender-mixed groups, including 31 men and 33 women aged ≥ 55 years old. Eight older adults participated in each FGD session, and all discussions were conducted in the local language (Kinyarwanda) using a pre-designed interview guide. The discussions were audio-recorded and transcribed verbatim and translated into English. The transcript was inductively analyzed using thematic analytical process. Results Three themes were identified from the data, predominantly related to motives and barriers of meat consumption. The motives of meat consumption included improved quality and taste of the diet, improving own health, and having a social function. Barriers of meat consumption were perceived to be related to health risks, sustainability concerns (depletion of resources), and religious beliefs. Lastly, it was widely perceived that meat was unavailable and economically inaccessible, thus meat consumption was perceived to be associated with improved wealth. Conclusion The findings revealed a low and declining meat consumption among older adults due to poverty. Improving financial capacity or strategic public health work to improve protein consumption in the elderly is necessary to meet nutritional needs and facilitate healthy aging.

“…Second, the LCA methodology is still at an early stage to account for potential carbon sinks such as carbon sequestration in soil organic matter (IDF, 2022) or opportunities for carbon offset through manure biodigestion (Aguirre-Villegas and Larson, 2017). Third, concerns have been raised also about the functional unit (Salou et al, 2017;Letelier et al, 2022a), the emission allocation methods (Mazzetto et al, 2022;Letelier et al, 2022a), as well as biases that appear when standard milk LCA procedures are applied to dual-purpose breed (Zehetmeier et al, 2012) or applied to low-income systems where livestock have multiple functionalities (Weiler et al, 2014). The strong emphasis on milk carbon footprint in the research realms may have had implications for policy-making.…”

Sustainability of dairy systems through the lenses of the sustainable development goals

In this paper, we propose to view the sustainability of dairy farming as nested within the sustainability of agriculture, a subset of the sustainability of food systems, which in turn could be construed as a subset of the national commitments of a country to achieve the Sustainable Development Goals (SDGs). Disciplinary, multidisciplinary, and interdisciplinary research are essential to study bio-physical system components and their interactions. However, when dairy farming is viewed as nested within broader societal systems, the inclusion of human elements calls for transdisciplinary research. Few of the 17 SDGs are left untouched by the livestock sector. Research should aim at identifying relevant farm-level metrics that are in alignment with any of the 231 indicators supporting the SDGs. We used two examples to illustrate the approach. In the first, SDG 13 (Climate Action) is used as a reminder that despite the current emphasis on reducing milk carbon footprint (kg CO2-e/kg milk), the contribution of the sector to Climate Action depends on reducing its annual emission (kg CO2-e/year; indicator 13.2.2). In the second example, indicator 2.4.1 (land use for sustainable agriculture) of SDG 2 (Zero Hunger) is used to illustrate the potential tradeoffs between Milk N/Intake N as a metric of nitrogen use efficiency at the cow level and metrics such as the input:output ratio of human-edible protein (Milk N/Intake of human-edible N) that prioritize the use of human-inedible feed in dairy rations as a way to enhance efficiency and circularity at the food system level.
