  1. In Xai Xai, Mozambique, many households were experiencing an average of four to five months of food shortage every year, affecting mainly fishers. Coupled with drought and changing climate, this coastal community needed to get food from other sources, such as sea. Ecosystem-based adaptation approaches such as fish farming, crab farming, and mangrove reforestation were used to address this food insecurity.

    Mangroves provide a nursery area for many marine species, most of which are important for food, like fish, crabs, and shrimp. Reforestation of mangroves has ensured the normal functioning of this ecosystem, which has in turn increased fishery productivity and yield, ensuring enhanced food security. The implementation of fish and crab farming has increased change resilience for the local community.

  2. An ecology method that can help solve food insecurity issues is EbA (ecosystem-based adaptation). This is the use of biodiversity and ecosystem services as the overall adaptation strategy to help people and communities adapt to the negative effects of climate change at local to global levels. Another method is an EbA that provides flexible, cost-effective, and broadly applicable alternatives for building robust food systems and reducing the impacts of climate change due to ecosystem degradation.

  3. We need new aproaches to help with the droughts and the food supply

  4. -To meet the food needs of today and tomorrow, ecosystem services, such as water provision, pollination, and maintenance of soil fertility must be enhanced. Farmers depend on soil microorganisms to maintain soil fertility and structure for crop production, and on wild species for crop pollination and pest and predator control.

  5. Mangroves provide a nursery area for many marine species, most of which are important for food, like fish, crabs, and shrimp. Reforestation of mangroves has ensured the normal functioning of this ecosystem, which has in turn increased fishery productivity and yield, ensuring enhanced food security. Since the mangroves have a home so do the animals therefore people can have food.

    Lessons learnt from EbA actions can help tackle the current food crisis. For example, in Xai Xai, Mozambique, many households were experiencing an average of four to five months of food shortage every year, affecting mainly fishers. Coupled with drought and changing climate, this coastal community needed to get food from other sources, such as sea. Ecosystem-based adaptation approaches such as fish farming, crab farming, and mangrove reforestation were used to address this food insecurity. These community-based and community-led interventions helped enhance the adaptive capacity, resulting in the establishment of fish ponds and crab growth cages, directly benefiting 98 households (490 people), including 10 households in crab farming, 20 households in fish farming, and 68 households in mangrove reforestation including four that are permanently involved in the mangrove nurseries. The people had to change from solely being fishermen to crab hunters, and mangrove reforesters.

  6. In Mozambique many people experience a serious draught effecting mainly fishers. Ecosystem based adaptation is anytime that helps people get used to these droughts and harsh climate problems that usually causes food shortages. Another system that helps with foot shortages is a form of eba that helps animals adapt to these harsh climates that would usually cause them to die off.

  7. Mangroves naturally provide nursing for marine species, and restoring those trees help the ecosystem. That way fishers can catch more fish. Enhancing soil quality, water, and pollination also helps the ecosystem produce food, which in turn helps the people farming it.

  8. If you learn from lessons from EBA action you can help solve the food isecurity crisis. 2 examples of how to fix the crisis is building fish ponds and crab growth cages in communities that need food. Another example would be mangrove reforestation.

  9. One ecological method that can help solve food insecurity issues is an ecosystem-based adaptation. This offers alternatives for building robust food systems and reducing the impacts of climate change. Also, mangroves provide a nursery area for many marine species which are important for food.

  10. EBA and we need to learn how to deal with droughht

  11. -One of such approaches is ecosystem-based adaptation (EbA) which provides flexible, cost-effective, and broadly applicable alternatives for building robust food systems and reducing the impacts of climate change.EbA is the use of biodiversity and ecosystem services as part of an overall adaptation strategy to help people and communities adapt to the negative effects of climate change at local, national, regional and global levels. It provides many other benefits to communities, including food security (from fisheries to agroforestry), sustainable water management, and livelihood diversification (through increasing resource-use options).
    -To meet the food needs of today and tomorrow, ecosystem services, such as water provision, pollination, and maintenance of soil fertility must be enhanced. Farmers rely on soil microorganisms to maintain soil fertility and structure for crop production, and on wild species for crop pollination and pest and predator control.
    Once we have learned how to produce a maximum amount of food without damaging the soil, we will then be able to reach sustainability.

  12. Mangroves are habitats for marine species which are a big food source, so we should help restore them. Also clean up pollution so species are not getting killed from pollution.

  13. Mangroves help most species survive so by helping those trees survive your helping the species survive. The more fish there are the easier it is to catch them. They also can focus on crab farming which splits off some off the fisherman which means that there will be more fish and more crabs because humans aren’t fishing them to death instead they are fishing them both an aural amount if that makes sense.

  14. By repairing the mangroves they are helping the fishing population get back to normal and with the mangroves back in full swing then the fish population has a chance to come back. Also with a lot of the farmers now focusing on the crab hopefully the burden for all the fish in decrease maybe there will be a perfect balance where they don’t over fish and they don’t under fish and have too many.

  15. All of the people night need new aproaches to help with the droughts and the food supply.

  16. to meet the food needs of todays society, ecosystem services such as water provision,and pollution need to befixed. Farmers depend on soil microorganisms to keep soil fertility and structure in order to produce crops, and on wild species for crop pollination and pest and predator control.

    with drought and changing climate, coastal communities need to get food from other sources, such as sea. Ecosystem-based adaptation approaches such as fish farming, crab farming, and mangrove reforestation to address this food insecurity. They help improve the adaptive capacity, resulting in fish ponds and crab growth.
