The Silent Crisis: Hunger amidst Abundance.
It's heartbreaking to know that almost a billion people go to bed hungry every night. The deep injustice in the way food is produced and accessed is to blame. The food sector reflects the economic and gender inequality that plagues our global economy. Women, who play a crucial role in food production, often face the greatest levels of hunger and are paid less than men. They work under degrading conditions, which is unacceptable and are more prone to gender based violence.
The increasing hunger crisis is further fueled by the worsening climate crisis. Supercharged storms, intense droughts, and rising sea levels make it harder to grow food. This disproportionately affects vulnerable communities and threatens their rights.
Without a secure livelihood for the people involved in putting food on our plates, food security becomes untenable. This goes beyond growers to include everyone in the food system - the processors who turn wheat into flour, the manufacturer who turn the flour into bread, the packagers who keep the bread fresh for longer, the distributors who transport the bread, and the retailers who sell it.
Climate change also puts pressure on land and natural resources, creating competition between poor communities and powerful interests.
In the midst of this crisis, it's important to explore alternative solutions.
Owning to water scarcity and environmental harzards of synthentic fertilizers, reducing water, dependence on animal based protein feed for livestock and chemical fertilizers is very urgent for sustainable agriculture.
Traditionally, to feed more people or livestock you simply farmed more land, but this approach is no longer viable. Instead we must make better use of existing farmland by boosting yields. With nearly two-thirds of agricultural land devoted to meat production, increasing productivity of pasture is crucial according to COP28: 7 food and agriculture innovations needed to protect the climate and feed a rapidly growing world.
Imagine a crop that can double its biomass within 2-3 days, requires minimal input costs, and has all.
AZOLLA, a small freshwater fern, often underestimated due to its small size, possesses remarkable attributes that make it a green goldmine could be a game-changer.
