The perceptions of farmers regarding communal feedlots and their role in reducing enteric methane emissions have received limited attention in research. This study aims to examine farmers' perceptions, assess awareness, and identify barriers to adopting feedlots as a climate-smart practice to enteric methane emissions in rural communities in the Eastern Cape Province, South Africa. 161 structured, paper-based questionnaires were distributed among smallholder cattle farmers around three feedlot locations.

Flooding is a global threat causing significant economic and environmental damage, necessitating a policy response and collaborative strategy. This study assessed global research trends and advances in geospatial and meteorological flood risk assessment (G_MFRA), considering the ongoing debate on flood risk management and adaptation strategies. A total of 1872 original articles were downloaded in BibTex format using the Web of Science (WOS) and Scopus databases to retrieve G_MFRA studies published from 1985 to 2023.

Article Synopsis
  • Cattle feedlots in sub-Saharan Africa struggle with heat stress, but there aren't enough good strategies to help them deal with it.
  • A review of 30 research articles showed that providing shade, clean water, and special foods can help cattle stay healthy in the heat.
  • Local cattle breeds that are naturally better at handling heat are important, and using breeding programs can make these breeds even more resilient.

The article presents and validates an extensive multivariate dataset that offers insights into water-energy-food (WEF) nexus governance for social justice at the intrahousehold, household, and community levels. The lack of insights in the WEF nexus debate that take social justice and governance into account is what spurred the data collection. The initial process involved scoping the originally selected investigated sites and their suitability.

Grass biomass composition and distribution patterns within the paddock as determinants of behavioral activities and animal performance of Nguni (NG) and Boran (BR) cattle post-relocation to a novel environment were examined. Ten steers of each breed aged 9 months were bought from two different farms and sent to Honeydale research facilities, where they were reared on rangelands for 12 weeks. Identification and classification of grass species were done every sampling week before introducing cattle to each paddock.

South Africa declared a State of National Disaster due to the COVID-19 pandemic, instituting a nationwide lockdown on 26 March 2020. Sale of goods and services classified as non-essential, such as tobacco and liquor, were prohibited, leading to widespread concerns about viability, job losses and investment in these industries. The study highlighted the impact of the COVID-19 lockdown on the South African alcohol and tobacco industries, taking the Johannesburg Stock Exchange-listed British American Tobacco (BTI) and Distell Group Limited (DGH) as cases.

A community-based intervention project was conducted, from April 2017 to March 2019, on 512 kids born from flocks of 30 purposively selected households located in ten villages within Alice district of the Eastern Cape Province, South Africa. The study aimed to examine the effectiveness of combined efforts from the research team and farmers to control disease outbreaks and climate change-related deaths. A systematic dosing and fortnight dipping schedule was part of the intervention efforts made by the research team as well as supplying feed to pregnant and lactating does.

It is estimated that South Africa's population will be above 65 million in 2050. Thus, food production needs to triple to alleviate poverty and food insecurity. However, infectious and non-infectious diseases affect livestock productivity, thereby hampering food supply.

The impact of climate-change disasters poses significant challenges for South Africa, especially for vulnerable rural households. In South Africa, the impact of climate change at the local level, especially in rural areas, is not well known. Rural households are generally poor and lack resources to adapt to and mitigate the impact of climate change, but the extent of their vulnerability is largely not understood.
