Regional summer climate variability and change over North America in the 20th Century
The climate of North America reflects the natural variability of global atmospheric circulation, and is impacted by two primary anthropogenic forcings: increasing concentrations of greenhouse gases (GHG) and Land Use/Land Cover Change (LULC). The objective of this thesis is to quantify the relative …

Modelling impacts of climate variability and change on wheat cropping across New South Wales
… being significantly affected by water stress and ongoing climate change. To accurately quantify crop yield, and estimate greenhouse gas emissions (GHG) at specific sites and regional scales, it is essential to link spatial information of agro-resources and crop simulation model to assess crop …

Vulnerability of horticulture producers to climate variability and change : the case of Chókwe District, Mozambique
Climate change is projected to have continued and globally severe environmental, economic and socioeconomic effects. These effects are forecast to be more severe in the agriculture sector, considering that it is one of the most sensitive industries to climate change. Studies from the Mozambican …

Understanding a high resolution regional climate model's ability in simulating tropical East Africa climate variability and change
… benefits of increasing resolution in regional climate models in the simulation of climate variability and change over East Africa. This study is based on two high resolution regional climate simulations with a horizontal resolution of 50km and 10km, respectively. These represent present day …

Impacts of Climate Variability and Change on Maize (Zea may) production in Makhuduthamaga Local Municipality, Limpopo Province, South Africa.
Climate variability and change directly affect agricultural production. This is because the agricultural sector is inherently sensitive to climatic conditions and is one of the most vulnerable sectors to risks and impact of global climate change. The aim of this study was to determine maize …

Analysing modelled nearshore wave climate variability and change as relevant to the traditional handline fishery of the South African South Coast
The South Coast traditional handline fishing communities of South Africa are integrated into a complex ecosystem where human and natural components interact and overlap on many different spatial and temporal scales. The South Coast marine ecosystem, on which the fishers depend, already suffers from …

Using micro-finance services to support climate change adaptation among small-scale farmers : identifying opportunities and challenges in southern Mozambique
… opportunities to invest in adequate technologies and practices required to respond to climate variability and change. In this context, this study explores how Microfinance Institutions (MFIs) can be capacitated in order to assist smallholder farmers to respond to climate change. The core objective …

A Systematic Evaluation of Climate Services and Decision Support Tools for Climate Change Adaptation
Climate services, often refers as decision support tools, are developed to provide information with a view to aid in decision making and policy planning for adaptation due to climate variability and change. This study investigated different publicly available climate services and decision support …

Snow Accumulation and Melt Timing at High Elevations in Northwest Montana
… sensitivity of snowmelt driven water supply to climate variability and change is difficult to assess in the mountain west, where strong climatic gradients coupled with complex topography are sampled by sparse ground measurements. We developed a snowmelt model, which ingests daily satellite …

Climate Change and Seed Security Among Smallholder Farmers in Northern Ghana
… agriculture is highly susceptible to climate variability and change. According to recent projections by the Intergovernmental Panel on Climate Change, this sensitivity would likely increase in the coming decades, with more erratic rainfall, prolonged dry periods, shorter growing …

The Impacts of Drought on Wheat Yield and Farmers' Livelihood in the Swartland Region of the Western Cape South Africa
… of South Africa. This is because the frequency and intensity of drought have increased in recent years, which have led to declines in crop yields and have negative implications on the production of non-irrigated crops such as wheat. This study examined the sensitivity of winter wheat to drought …

An analysis of organisational adaptation to climate change: the case of the Bardiya National Park
This research is concerned with understanding how the management authority of the Bardiya National Park (the BNPMA) is able to adapt to the pressures of increasing climate variability and change. To that end, this study employs a mixed-methods case study approach to elucidate the key drivers of …

Climate change impacts and farmers' responses in Chilanga District, Zambia
Climate change and variability are predicted to threaten agricultural production in Southern Africa. For example, Zambia's agriculture remains vulnerable to climate change and variability due to the small-scale farmers' dependence on rain-fed agriculture. Some studies in Zambia have shown the …

Ireland’s pre-1940 daily precipitation data: data rescue, quality assurance and analysis of extremes
… This research presents daily rainfall data and metadata for Ireland transcribed from historical manuscripts and printed copies of rainfall registers located in Met Éireann's archives. To facilitate the transcription of rainfall observations from paper records, the historical manuscripts were …

Assessment of Future Impact of Climate Change on Structural Protections and Hydrological Extremes – Floods
The certainty of flood protection in the face of climate change is linked to the likelihood that a system will function reliably under various future flood scenarios. It is increasingly crucial to comprehend and forecast the frequency and intensity of random hydrological factors for efficient flood …

Evaluation of water governance systems for improved operation of selected small-holder irrigation schemes in Nzhelele Area, South Africa
… sustaining rural livelihoods, adapting to climate variability and change, and reducing poverty in rural areas. South Africa prioritises the establishment, rehabilitation and revitalization of small-holder irrigation schemes due to their potential in poverty reduction and enhancing food and …

Conceptualising and quantifying the nonlinear, chaotic climate: implications for climate model experimental design
Uncertainty in climate system initial conditions (ICs) is known to limit the predictability of future atmospheric states. On weather time scales (i.e. hours to days), the separation between two atmospheric model trajectories, initially "indistinguishable" (compared to unavoidable uncertainties) …

Can sociality buffer the impacts of climate change on a cooperatively-breeding bird, the southern pied babbler Turdoides bicolor?
Increasingly harsh and unpredictable climate regimes are affecting animal populations everywhere and understanding how species respond to current environmental variability is important for predicting vulnerability to climate change over longer timescales. Species living in characteristically harsh …
