It has been designed to simulate the dynamics and interconnections between three major subsystems on earth i. Overview Integrated Assessment Models IAM are mathematical computer models based on explicit assumptions about how the modelled system behaves.
The strength of an IAM is its ability to calculate the consequences of different assumptions and to inter-relate may factors simultaneously, but an IAM is constrained by the quality and character of the assumptions and data that underlie the model. Most climate change integrated assessment projects now underway are developing an integrated model. These models provide a very useful framework or methodology for organising and assessing information and for conducting research. They allow for consistency in the integration and assessment of information, and they are useful in illustrating where research and knowledge is lacking as well as having insights into the consequences of different policy options.
Integrated assessment models generally include both physical and social science models that consider demographic, political, and economic variables that affect greenhouse gas emission scenarios in addition to the physical climate system. Climate change IAMs are tools that bring together very different types of information e.
IAMs cannot provide "the answer" about how to respond to the climate change problem. IAMs, however, can provide a framework for understanding the climate change problem and for informing judgements about the relative value of different option for dealing with climate change.

In this sense, they can be used in a predictive mode, quantifying scenarios. In predictive mode, formal sensitivity analysis must be developed as part of the global modelling exercise to estimate the uncertainty of calculations. Different IAMs exist, however each one approaches the climate change issue in a different manner. For example, some models focus more on economic issues e.
Regional energy consumption, energy efficiency improvement, fuel substitution, supply and trade of fossil fuels and renewable energy technologies are simulated with the specific energy model to calculate energy production, energy use, industrial production, emissions of greenhouse gases, ozone precursors and sulphur. Ecosystem, crop and land-use models are used to compute land use on the basis of regional consumption, technological developments, production and trading of food, animal feed, grass and timber, and local climatic and terrain properties. The use of detergent is modelled on the base of GDP and assumptions on specific policies and the resulting impact on water quality are assessed.
Adapted from. Tips Before choosing an IAM, the following issues should be considered:. These culprits are, in descending order: 1 changes in land and sea use; 2 direct exploitation of organisms; 3 climate change; 4 pollution and 5 invasive alien species. The Report notes that, since , greenhouse gas emissions have doubled, raising average global temperatures by at least 0. Despite progress to conserve nature and implement policies, the Report also finds that global goals for conserving and sustainably using nature and achieving sustainability cannot be met by current trajectories, and goals for and beyond may only be achieved through transformative changes across economic, social, political and technological factors.
Agriculture and Its Impact on Land‐Use, Environment, and Ecosystem Services
With good progress on components of only four of the 20 Aichi Biodiversity Targets, it is likely that most will be missed by the deadline. Loss of biodiversity is therefore shown to be not only an environmental issue, but also a developmental, economic, security, social and moral issue as well. The Report also presents a wide range of illustrative actions for sustainability and pathways for achieving them across and between sectors such as agriculture, forestry, marine systems, freshwater systems, urban areas, energy, finance and many others.
It highlights the importance of, among others, adopting integrated management and cross-sectoral approaches that take into account the trade-offs of food and energy production, infrastructure, freshwater and coastal management, and biodiversity conservation. Also identified as a key element of more sustainable future policies is the evolution of global financial and economic systems to build a global sustainable economy, steering away from the current limited paradigm of economic growth. Anne Larigauderie. UN Environment is proud to support the Global Assessment Report produced by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services because it highlights the critical need to integrate biodiversity considerations in global decision-making on any sector or challenge, whether its water or agriculture, infrastructure or business.

The magic of seeing fireflies flickering long into the night is immense. We draw energy and nutrients from nature. We find sources of food, medicine, livelihoods and innovation in nature. Our well-being fundamentally depends on nature. Our efforts to conserve biodiversity and ecosystems must be underpinned by the best science that humanity can produce. Our local, indigenous and scientific knowledge are proving that we have solutions and so no more excuses: we must live on earth differently. UNESCO is committed to promoting respect of the living and of its diversity, ecological solidarity with other living species, and to establish new, equitable and global links of partnership and intragenerational solidarity, for the perpetuation of humankind.
Healthy biodiversity is the essential infrastructure that supports all forms of life on earth, including human life.

It also provides nature-based solutions on many of the most critical environmental, economic, and social challenges that we face as human society, including climate change, sustainable development, health, and water and food security. We are currently in the midst of preparing for the UN Biodiversity Conference, in China, which will mark the close of the Aichi Biodiversity Targets and set the course for a post ecologically focused sustainable development pathway to deliver multiple benefits for people, the planet and our global economy.
I want to extend my thanks and congratulations to the IPBES community for their hard work, immense contributions and continued partnership. Together, assessments undertaken by IPBES, FAO, CBD and other organizations point to the urgent need for action to better conserve and sustainably use biodiversity and to the importance of cross-sectoral and multidisciplinary collaboration among decision-makers and other stakeholders at all levels.
Current global response insufficient;. Further Information on Key Issues from the Report Scale of Loss of Nature Gains from societal and policy responses, while important, have not stopped massive losses. Since , trends in agricultural production, fish harvest, bioenergy production and harvest of materials have increased, in response to population growth, rising demand and technological development, this has come at a steep price, which has been unequally distributed within and across countries.
