The interrelationship between freshwater availability with the growing population and climate change estimates is complex. This article investigates climate change role in freshwater resources availability. This is critical issue as freshwater is vital resource for life, and it is in stake as it is depleted worldwide. Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) was discussed. This paper elucidates the climate model downscaling methods used by scholars for future projections. The applications of modelling could provide a holistic approach based on historical data to predict the effect of climate change on the availability of freshwater. However, the people variability uncertainties dominate assessments of freshwater stress, whilst climate change projections uncertainties are more hypothesized to play a smaller role than people.

Freshwater Availability

The coming decades will present an immense challenge for the planet: sustainably feeding nearly ten billion people that are expected to be alive by 2050. This is no small task, and one that intersects with climate change, geopolitics, the increased globalization of agricultural markets, and the emergence of new technologies. The world faces a challenge of increased demand, propelled by an expanding world population and a global shift in dietary patterns toward more resource-intensive foods. Moreover, changes in demand occur in the context of declining soil fertility and freshwater availability, agriculture's growing contribution to water pollution and climate change, and the emerging threats to agricultural productivity caused by climate disruption.

Freshwater Availability

Abstract Warmer and shorter winters from climate change will reduce snowpacks in most seasonally snow-covered regions of the world, with consequences for freshwater availability in spring and summer when people and ecosystems demand water most. Recent record low snowpacks, such as those in the winters of 2013/14 and 2014/15 in the Western United States, have led to a surge in research on ‘snow droughts,’ which are pointed to as harbingers of global warming that pose significant societal hazards. Yet despite the importance of understanding snow droughts to best prepare for their attendant impacts, the concept remains amorphous, with no agreed-upon definition of what they are, how best to measure them, and how such snow droughts connect to warm-season impacts. These knowledge gaps limit our understanding of the risks posed by snow droughts in the present and future, and thus our preparedness for their differential impacts on freshwater resources. To address these issues, we compile a hemispheric ensemble of in situ, satellite, and reanalysis snowpack datasets. We use this ensemble to evaluate the scientific challenges and uncertainties arising from differences in defining and measuring snow droughts, and identify opportunities to leverage this information to better understand the significance of snow droughts. We show that a clearer quantification of what constitutes a snow drought, including its uncertainties, improves our ability to anticipate costly and disruptive warm-season droughts, which is vital for informing risk management and adaptation to changing snow regimes.

Insect Interactions

Food security and the sustainability of native ecosystems depends on plant-insect interactions in countless ways. Recently reported rapid and immense declines in insect numbers due to climate change, the use of pesticides and herbicides, the introduction of agricultural monocultures, and the destruction of insect native habitat, are all potential contributors to this grave situation. Some researchers are working towards a future where natural insect pollinators might be replaced with free-flying robotic bees, an ecologically problematic proposal. We argue instead that creating environments that are friendly to bees and exploring the use of other species for pollination and bio-control, particularly in non-European countries, are more ecologically sound approaches. The computer simulation of insect-plant interactions is a far more measured application of technology that may assist in managing, or averting, ‘Insect Armageddon' from both practical and ethical viewpoints.
