Climate change is one of the biggest environmental challenges we face. It is already affecting our region, and current impacts are will continue and intensify into the future. While we are uncertain about the pace and scale of change, we do know that the Horizons Region is already being affected by increasing temperatures, changes to rainfall patterns, river flows, increased drought, and ongoing sea-level rise. A changing climate will also affect our economy, and way of life. With these factors combined, this issue must be addressed with urgency.
Share your thoughts on climate change with us here
On Monday 7 September Horizons started a conversation, on behalf of our region's city and district councils, with our community asking what their values are as we begin to build a Regional Climate Change Risk Assessment. Community values are the ‘things and objects’ of value that could be affected by climate change at any location in the region that you have a connection to, regardless of where you live, work or play. These ‘things and objects’ could be either physical objects e.g. buildings, roads, native species or less tangible things e.g. community cohesion and cultural practices. Share your thoughts or concerns with us by 4 October on our Social Pinpoint page here.
We also welcome feedback via email or mail through climatechange@horizons.govt.nz and Freepost 217922, Private Bag 11025, Manawatu Mail Centre, Palmerston North 4414.
This changing climate is likely to lead to changes in land-use suitability and impacts on primary production. Changing weather patterns, such as a warmer climate, may provide new opportunities for horticulture or cropping in some areas. However, we will also face significant challenges like more frequent and serious flooding. Climate change is not a problem for the distant future: some of these changes are already starting to be felt. By responding now, we can make our communities more resilient and reduce the overall costs associated with climate change. Flooding Changes in extreme weather are likely to increase the frequency and magnitude of flood events. Erosion More extreme rainfall and more frequent storm events are likely to increase soil erosion, particularly from hill country areas. Drought Reduced rainfall and increased evapotranspiration (transfer of water from land to the atmosphere) are likely to increase incidence of drought across the region; particularly to the east of the Ruahine Ranges. Water availability Seasonal changes in rainfall totals are likely to reduce water availability – particularly during the summer months. Projected changes in rainfall vary spatially across the region. It is anticipated that east of the region will get drier, while the north and west will get wetter. Sea level rise and coastal erosion Sea levels are projected to rise – this will impact how we live near and use coastlines.
Naturally occurring greenhouse gases trap heat in the earth’s atmosphere; they are vital to support life on earth. However, human activities over the last 150 years have released excess amounts of greenhouse gases into the atmosphere, trapping too much heat. The release of these gases is the major cause of climate change. Major greenhouse gases:
We are working with other agencies in our region and nationally to respond to climate change and support the transition to a sustainable regional economy. A number of our current work streams align with climate change adaptation - including management of soil erosion and its impacts, flood schemes and emergency management activities. These programmes build resilience for our communities, although climate change has not been the primary driver. We are taking steps to integrate climate change considerations more actively into our business planning decisions.
A cross-organisational team has been established to develop a Climate Change Strategy for Horizons. The aim of this strategy is to:
Alongside our information, here is a variety of other useful and relevant climate change resources that are available. NIWA’s mission is to conduct leading environmental science to enable the sustainable management of natural resources for New Zealand. Read their climate change information here. Resources from the Royal Society to help you discover what climate change will mean for New Zealand. The mission of the Deep South Challenge is to enable New Zealanders to adapt, manage risk, and thrive in a changing climate. Find out more here. Read all things climate change from the Ministry for the Environment, including what the Government is doing, and why climate change matters. This first national climate change risk assessment from MfE helps the Government identify where it needs to prioritise action. Read the report here. Our Future Climate New Zealand is an interactive website designed by NIWA to give you the ability to look at a number of climate change projections for New Zealand. Toitū Envirocare's have a range of different environmental calculaters available to calculate and offset emissions for your travels, or your household activities.
