As part of the 2030 Agenda for Sustainable Development, achieving a world without hunger and malnutrition calls for urgent action to make agriculture more sustainable, productive and resilient.
The impacts of climate change are further increasing uncertainties and vulnerabilities facing farmers and communities.
Integrated, cross sectoral approaches like agroecology are an important element in the transition process, reducing the environmental footprint of agriculture to guarantee healthy ecosystems that can ensure food and nutrition security for all.
On the base of case studies and interviews from farmers, researchers and decisions makers from France, Mali, Hungary , Argentina this video show how agroecology and political will can help build more resilient farming systems and question the future requirements to up-scale these solutions.

Indonesia is preparing to deploy hundreds of soldiers to its eastern provinces in an effort to combat separatist groups.
Recent shoot-outs with armed fighters in Papua and West Papua have forced villagers to flee their homes.
There is now concern the government's decision to designate Papuan groups as terrorists may inflame tensions even further.

Researchers have offered a chemical explanation for sex change in a tropical fish. ↓↓More info and references below↓↓
For a tropical fish called the bluehead wrasse, sex isn’t always permanent. When a group of the fish loses its dominant male, the biggest female rapidly changes sex, taking on distinctive male coloring and producing mature sperm in as little as 8 days. Although this change is well documented, the molecular mechanisms that drive it have remained unclear. Now, an international group of researchers has offered a chemical explanation for the transformation after analyzing tissue samples from transitioning fish.
