Sustainable Development

- [Instructeur] Duurzame ontwikkeling is de praktijk om in de huidige menselijke behoefte te voorzien en er tegelijkertijd voor te zorgen dat ook de toekomstige generaties in hun eigen behoeftes kunnen voorzien. Drie belangrijke ontwikkelingsgebieden, sociaal, economisch en ecologisch zijn met elkaar verweven binnen dit concept. Vanuit een biologisch oogpunt vereist duurzame ontwikkeling onderzoek om ecologische kwesties te begrijpen en om instandhoudingsinspanningen te implementeren om biodiversiteit en natuurlijke hulpbronnen te behouden.

Onderzoek naar hoe organismes met elkaar en met hun omgeving omgaan en hoe ecosystemen door menselijke activiteiten worden beïnvloed, kunnen de inspanningen om de levensstandaard van mensen te handhaven of te verbeteren stimuleren, terwijl het tegelijkertijd het dierenrijk beschermt en de biodiversiteit behoudt. De energiebehoeften van industrielanden vormen een belangrijke milieu-uitdaging in duurzame ontwikkeling. De energievoorziening is nog steeds sterk afhankelijk van fossiele brandstoffen, maar ze zijn een eindige bron.

Bovendien komt er bij de verbranding van deze brandstoffen koolstofdioxide vrij in de atmosfeer, wat klimaatverandering in de hand werkt. Het vervangen van fossiele brandstoffen door hernieuwbare energiebronnen, zoals wind- en zonne-energie, is een voorbeeld van duurzame ontwikkeling in actie. Land en water zijn ook eindige hulpbronnen, dus duurzame ontwikkeling in de landbouw is essentieel om nu en in de toekomst voldoende voedsel voor mensen te produceren.

De vruchtwisseling op akkerland is een voorbeeld van een duurzame landbouwpraktijk. Door gewasrotatie wordt het verlies aan voedingsstoffen in de grond mettertijd tot een minimum beperkt, wat een efficiëntere gewasgroei mogelijk maakt en de impact van ongedierte dat specifieke gewassen, zoals maïs, in meerdere groeiseizoenen teistert, vermindert.

duurzame ontwikkeling

Terwijl de menselijke bevolking blijft groeien en hulpbronnen blijft gebruiken, moeten we ons bewust zijn van de natuurlijke grenzen van onze planeet. Duurzame ontwikkeling biedt een manier om het menselijk leven nu in stand te houden en te verbeteren en er tegelijkertijd voor te zorgen dat toekomstige generaties over de middelen zullen beschikken die ze nodig hebben. Het langetermijnsucces van duurzaamheidsinspanningen berust op het begrijpen van de wisselwerking tussen menselijk handelen en ecologische systemen.

De oceanen zijn een belangrijk aandachtspunt van de mondiale natuurbehoudsinspanningen. Overbevissing, vervuiling en de gevolgen van klimaatverandering, zoals verzuring van de oceanen en de stijgende zeespiegel, zijn slechts enkele van de belangrijkste problemen die moeten worden aangepakt om de oceanen van de wereld te beschermen. De oceanen leveren niet alleen enorme hoeveelheden voedsel voor de mens, maar zijn ook een belangrijke bron van zuurstof in de lucht en vormen een koolstofput voor CO2-gas. Ze helpen ook bij het reguleren van het klimaat en beïnvloeden weerpatronen over de hele wereld.

Een belangrijk aandachtspunt van duurzame ontwikkeling is de oceaanvisserij. Moderne visserijmethoden maken het mogelijk om grote aantallen vissen tegelijk te verzamelen, wat op de korte termijn efficiënt is, maar ook lokale uitputting van vispopulaties veroorzaakt, wat gevolgen kan hebben voor het voedselweb in de oceaan. De huidige grootschalige visserijmethoden leiden ook tot de dood van andere dieren, zoals dolfijnen en zeevogels, die samen met de beoogde doelvissen in netten worden gevangen. Daarom werken natuurbeschermingsorganisaties samen met de visserijsector om nieuw vistuig te ontwerpen dat onbedoelde vangsten voorkomt. Bovendien zijn er voorschriften uitgevaardigd om de uitputting van commercieel waardevolle vispopulaties te voorkomen. Op de lange termijn zijn dergelijke inspanningen ook gunstig voor mensen, die alleen kunnen blijven vertrouwen op vis als voedselbron als deze niet met uitsterven bedreigd wordt.

Duurzame ontwikkeling is bedoeld om de levens van mensen te verbeteren, maar om succesvol te zijn, moet deze ook een zorgvuldig beheer omvatten van ecosystemen en de andere organismen die de planeet met ons delen.

protecting oceans for sustainable development

Sustainable development depends on protecting oceans while meeting human needs. As the human population grows and uses more resources, people must stay aware of the planet’s natural limits. The goal is to improve life now without taking away the resources future generations will need.

Long-term sustainability depends on understanding how human actions affect ecological systems. Oceans are a major part of this balance. They provide food for people, produce much of the atmosphere’s oxygen, and act as a carbon sink, which means they absorb and store carbon dioxide. Oceans also help regulate climate and shape weather patterns around the world.

Ocean conservation faces several major problems. Overfishing can reduce local fish populations and affect the entire ocean food web. Pollution, ocean acidification, and rising sea levels are also serious concerns linked to climate change. These pressures make it harder to protect marine ecosystems and the services they provide.

Fishing is one of the main areas where sustainable development is needed. Modern fishing methods can catch many fish at once, which is efficient in the short term. But these methods can also lead to unwanted catches, including dolphins and sea birds, and can deplete commercially valuable fish populations. Conservation groups and the fishing industry are working on new gear that reduces bycatch, the accidental capture of non-target animals. Regulations also help limit overuse of fish stocks. In the long run, these efforts support both ocean life and people who depend on fish as a food source.

what is weather?

How Sunlight Shapes Daily Weather

Weather is the current state of the atmosphere at a specific time and place. It is temporary and changes from one location to another. Weather is shaped by the interaction of the sun, atmosphere, hydrosphere, and geosphere. Solar radiation reaches Earth and interacts with water and land. These surfaces release that energy as thermal radiation, or heat, which warms the air above them. Some of that heat escapes back into space, but some is trapped by atmospheric gases. This heat retention is...

global climate change

Ancient Clues to Climate Change

Ancient climate clues help scientists track global climate change. Paleoclimatology is the study of climate conditions in Earth’s past and the causes and effects behind them. By comparing recent climate patterns with older records, researchers can find strong evidence for human-caused warming. Earth’s climate has changed many times over its 4.5 billion year history. In the last 650,000 years, there have been seven cycles of glacial advance and retreat. The most recent ice age ended more than...

what is biodiversity?

Biodiversity Across Genes, Species, and Ecosystems

Biodiversity is the variety of living things at the genetic, species, and ecosystem levels. It includes not only how many kinds of organisms exist, but also how they are related and how they interact with the world around them. Species diversity spans the full evolutionary tree. It includes single-celled prokaryotes such as bacteria and archaea, as well as the eukaryotic kingdoms: plants, animals, fungi, and protists. About 1.75 million species have been identified so far, and scientists...

threats to biodiversity

How Humans Change Biodiversity

Human activity is changing biodiversity and pushing Earth toward a sixth extinction event. Earlier mass extinctions ended many species, and then new species spread into the changed environment. Today, the Holocene epoch is seeing a mass extinction linked to human actions, and it is often called the Anthropocene. Human numbers and human biomass show how large this impact has become. In 2019, the human population reached 7.7 billion and is projected to rise to 10 billion by 2060. By biomass,...

conservation of declining populations

Saving Species Through Population Recovery

Conservation of declining populations focuses on detecting a population drop, finding its cause, and stopping further loss. The goal is to prevent extinction by using scientific methods to identify the agents behind the decline. Once the cause is known, conservation teams can remove, oppose, or neutralize it. A common step is to test possible causes with a small trial group. If the cause is confirmed, the remaining animals may be moved to an unaffected area. When the population is too small or...

biodiversity and human values

Biodiversity in Food, Tools, and Medicine

Biodiversity supports human life through food, tools, medicine, and many other needs. Changes in the variety of species can also change the environment. Those environmental shifts can alter weather patterns and affect human civilizations. People have depended on biodiversity for agriculture since early human history. Agriculture began when ancestral humans found species that were good sources of food. At least 11,000 years ago, people started selecting plant and animal species to raise on...

what is conservation biology?

Protecting Biodiversity in Conservation Biology

Conservation biology is the science of protecting biodiversity and keeping ecosystems healthy. It looks at how living things, habitats, and human needs are connected. The goal is to preserve biodiversity so ecosystems can continue to function well. Healthy ecosystems provide people with important natural resources. These include food, medicines, and building materials. Ecosystems also deliver key services, such as cleaning air and water. Evidence shows that these services depend on...

what is climate?

Climate Patterns and Earth’s Energy Balance

Climate describes the usual weather conditions in a place over a long period of time. The idea is simple: climate is what you expect, while weather is what you get. Climate is shaped by geographic factors such as latitude, terrain, and how close an area is to bodies of water. Weather and climate are related, but they work on different time scales. Weather is the state of the atmosphere at a specific time and place. Climate is the average pattern of weather over much longer periods. Because of...

conservation of small populations

Saving Small Populations with Genetic Diversity

Small populations can be hard to save because they often lose genetic diversity. When variation is low, a species has fewer traits that may help it adapt to climate change, competition from other species, or new diseases. That makes extinction more likely. Large populations usually have a better chance of surviving new stresses. They are more likely to include individuals with genetic variants that are helpful in changing conditions. Small populations are much less likely to contain this kind...

habitat fragmentation

How Fragmented Habitats Affect Wildlife

Habitat fragmentation breaks one continuous habitat into smaller, separate patches. Human land conversion is a major cause of this change, and slower geological shifts in the physical environment can also fragment habitats. The process usually follows the same stages: perforation, dissection, fragmentation, shrinkage, and attrition. Perforation and dissection often begin during land development. Perforation happens when undeveloped land is cleared for something like a home, and dissection...
