(SEA Directive)An EU-wide network of nature protecti<strong>on</strong> areas established under the Habitats Directive. The aimof the network is to assure the l<strong>on</strong>g-term survival of Europe’s most valuable <strong>and</strong> threatened species<strong>and</strong> habitats. It is comprised of Special Areas of C<strong>on</strong>servati<strong>on</strong> (SAC) designated by Member Statesunder the Habitats Directive <strong>and</strong> Special Protecti<strong>on</strong> Areas (SPAs) designated under the BirdsDirective.The point where biodiversity gains from targeted c<strong>on</strong>servati<strong>on</strong> activities match the losses ofbiodiversity due to the impacts of a specific development project, so that there is no net reducti<strong>on</strong>overall in the type, amount <strong>and</strong> c<strong>on</strong>diti<strong>on</strong> (or quality) of biodiversity over space <strong>and</strong> time. A netgain means that biodiversity gains exceed a specific set of losses. The c<strong>on</strong>cept of no-net biodiversityloss lies at the heart of biodiversity offsetting. (Business <strong>and</strong> <strong>Biodiversity</strong> Offsets Programme)‘No-regret’ measures are activities that yield benefits even in the absence of climate change. Inmany locati<strong>on</strong>s, the implementati<strong>on</strong> of these acti<strong>on</strong>s c<strong>on</strong>stitutes a very efficient first step in a l<strong>on</strong>gtermadaptati<strong>on</strong> strategy. For example, c<strong>on</strong>trolling leakages in water pipes or maintaining drainagechannels is almost always c<strong>on</strong>sidered a very good investment from a cost–benefit analysisperspective, even in absence of climate change. (CLIMATE-ADAPT relevant webpage)Principle adopted by the UN C<strong>on</strong>ference <strong>on</strong> the Envir<strong>on</strong>ment <strong>and</strong> Development (1992) that in orderto protect the envir<strong>on</strong>ment, a precauti<strong>on</strong>ary approach should be widely applied, meaning thatwhere there are threats of serious or irreversible damage to the envir<strong>on</strong>ment, lack of full scientificcertainty should not be used as a reas<strong>on</strong> for postp<strong>on</strong>ing cost-effective measures to preventenvir<strong>on</strong>mental degradati<strong>on</strong>.

It requires the envir<strong>on</strong>mental effects of a broad range ofplans <strong>and</strong> programmes to be assessed so they can be c<strong>on</strong>sidered while plans are actually beingdeveloped, <strong>and</strong> in due course adopted. The public must also be c<strong>on</strong>sulted <strong>on</strong> the draft plans <strong>and</strong>the envir<strong>on</strong>mental assessment, <strong>and</strong> their views must be taken <strong>into</strong> account.Effects that occur as a c<strong>on</strong>sequence of a primary effect or as a result of a complex pathway (seealso indirect effects).The degree to which a system is affected, either adversely or beneficially, by climate-relatedstimuli. The effect may be direct (e.g. a change in crop yield in resp<strong>on</strong>se to a change in the mean,range, or variability of temperature) or indirect (e.g. damages caused by an increase in thefrequency of coastal flooding due to sea level rise).Effects that are significant in the c<strong>on</strong>text of the PP, i.e. a functi<strong>on</strong> not just of magnitude or size ofeffect, but of nature, sensitivity <strong>and</strong> scale of the receptor.Effects that interact to produce a total effect greater (or less than) than the sum of the individualeffects. Cumulative effects that result when the interacti<strong>on</strong> of a number of impacts is greater thanthe sum of the individual impacts.The degree to which a system is susceptible to, or unable to cope with, adverse effects of climatechange, including climate variability <strong>and</strong> extremes. Vulnerability is a functi<strong>on</strong> of the character,magnitude, <strong>and</strong> rate of climate change <strong>and</strong> variati<strong>on</strong> to which a system is exposed, its sensitivity,<strong>and</strong> its adaptive capacity.
