Commercial Farming Adaption to Drought as a Strategy for Stable Local Economic Growth in Ugu District Municipality
… is regarded as the sector that mostly relies on climate conditions for its productivity, yet in recent years this sector has been experiencing droughts. The study attempted to explain how commercial farming adaptation to droughts maybe be used as a strategy for stable Local Economic Growth (LEG) …

Floral trait architecture in crop sunflower (<i>Helianthus annuus</i>) under drought conditions
<p>Longer and more intense droughts are predicted to become more common in the coming century due to anthropogenic climate change. Drought can reduce crop yield and decrease food security. In order to mitigate the negative effects of drought on crop production, it is important to elucidate the …

Physiological and Morphological Responses to Drought Stress in Different Cultivation Environments in Wild Type and ABA-deficient Barley
… is increasingly threatened by the effects of climate change. Of the environmental factors affected by climate change, drought is one of the most critical for plant survival and reproduction, shaping plant morphology and physiology and therefore crop productivity. Although the effects of …

Temporal information partitioning networks to infer ecohydrologic behaviors
… to understand ecohydrologic systems across climate gradients based on flux tower and weather station observations. In the TIPNet framework, nodes in the network are time-series variables, and links are information theoretic measures that quantify multivariate lagged time-dependencies from …

Modelling the economic and social consequences of drought under future projections of climate change
Drought events and their consequences pose a considerable problem for governments, businesses and individuals. Superimposed on this risk is the danger of future anthropogenic climate change. Climate models are increasingly being used to understand how climate change may affect future drought …

Agro-Climatic Change, Crop Production and Mitigation Strategies-Case Studies in Arkansas, USA and Kenya
<p>Although climate change impacts vary geographically and temporally, studies at local levels are not readily available for stakeholders to better understand how their local communities would be affected and what remedial measures could be more effective in their local contexts. This dissertation …

Vegetative and reproductive biomass allocation responses of herbaceous plant species to induced drought in a semi–arid highland savanna, central, Namibia
… conditions renders its vegetation vulnerable to changes in precipitation, affecting plant growth and biomass allocation. Recurring droughts, intensified by climate change lead to alterations in biomass allocation. Thus resulting in the reduction of medicinal products, livestock fodder, and food …

Exploring the impact of abiotic stress on Brassica and tomato: morphophysiology and microbiome dynamics [Analisi dell'impatto dello stress abiotico su Brassica e pomodoro: morfofisiologia e dinamiche del microbioma]
I cambiamenti climatici e la crescente domanda globale di alimenti rendono necessaria la creazione di specie vegetali resilienti agli stress abiotici e compatibili con pratiche agricole sostenibili. In questa tesi sono stati investigati due approcci complementari: la base genetica della tolleranza …

Potential impacts of climate change and land-use change on hydrological drought in the Western Cape (South Africa)
… Africa) recently witnessed the most severe drought on record. The meteorological drought, which was characterised by below-normal rainfall for three consecutive years (2015 – 2017), cascaded to agricultural and then hydrological drought, resulting in devastating socio-economic consequences. …
