Advancements in the satellite sensing of the impacts of climate and variability on bush encroachment in savannah rangelands
(Elsevier, 2022)An increase in shrubs or woody species is likely, directly or indirectly, to significantly affect rural livelihoods, wildlife/livestock productivity and conservation efforts. Poor and inappropriate land use management ... -
Assessing the relationship between youth capabilities and food security: A case study of a rainwater harvesting project in South Africa
(AJOL, 2015)Rainwater harvesting presents a viable option for securing water availability in order to increase food production. The study focuses on rural youth in Luphisi and Dwaleni villages in the Mpumalanga Province and considers ... -
Assessment of concentration levels of contaminants in groundwater of the Soutpansberg region, Limpopo Province, South Africa
(MDPI, 2022)Groundwater contributions towards improved food security and human health depend on the level of contaminants in groundwater resources. Many people in rural areas use groundwater for drinking purposes without treatment ... -
Common bean as a potential crop for future food security: an overview of past, current and future contributions in genomics, transcriptomics, transgenics and proteomics
(Taylor & Francis Open Access, 2021)Common bean is an important legume crop having high quality protein, micronutrients, vitamins and antioxidants, which makes it a “grain of hope” for poor communities. Hence, a good number of breeding activities have been ... -
A decade of plant proteomics and mass spectrometry: Translation of technical advancements to food security and safety issues
(Wiley, 2013)Tremendous progress in plant proteomics driven by mass spectrometry (MS) techniques has been made since 2000 when few proteomics reports were published and plant proteomics was in its infancy. These achievements include ... -
Decoding heavy metal stress signalling in plants: Towards improved food security and safety
(MDPI, 2020)The mining of heavy metals from the environment leads to an increase in soil pollution, leading to the uptake of heavy metals into plant tissue. The build-up of toxic metals in plant cells often leads to cellular damage ... -
Genetic variation in responses to salt stress in Tunisian populations of Medicago ciliaris
(MDPI, 2022)Soil salinity is one of the most serious environmental factors affecting crop productivity around the world. We used a morpho-physiological approach to investigate the salt responses of four Tunisian natural populations ... -
Indigenous African cereal crops can contribute to mitigation of the impact of climate change on food security
(Arid land institute, 2021)Zea mays L. (maize) is one of the top three cultivated cereals globally, along with wheat and rice. The United States, China, and Brazil are among the largest producers of maize, producing approximately 79% of the world’s ... -
Progress in the use of geospatial and remote sensing technologies in the assessment and monitoring of tomato crop diseases
(Taylor and Francis Group, 2022)With a growing global population and accelerating climatechange, systematic assessment and monitoring of crop diseases isurgently required to ensure food security and production.However, current dietary transitions ... -
Stakeholder-derived recommendations and actions to support deep-reef conservation in the Western Indian Ocean
(Wiley, 2022)Deep reefs below 30mprovide essential ecosystem services for ocean health and human well-being such as food security and climate change resilience. Yet, deep reefs remain poorly researched and largely unprotected, including ... -
Sustainable agriculture through the enhancement of microbial biocontrol agents: Current challenges and new perspectives
(MDPI, 2023)The future of pesticide usage in agriculture is uncertain due to its unsustainability, adverse environmental impacts, and its association in enhanced phytopathogen resistance. Hence, this situation urges the development ...
