Citizens' rights to plant and access independent food are guaranteed by Law Number 18 of 2012 concerning Food. This regulation explicitly mandates the central and regional governments to optimize idle land and public facilities for food availability. In addition, Government Regulation Number 17 of 2015 reaffirms that household food independence is a main pillar of national resilience that must be legally supported.

At the local level, policies such as Governor of DKI Jakarta Instruction Number 14 of 2018 provides legal protection for citizens who utilize public assets for urban agriculture. The public must be bold in using this legal instrument as a basis for advocacy to green their alleys. Spatial politics must side with the interests of ecology and the people's livelihoods, not merely aesthetic interests or physical development alone.

Resource Efficiency in Urban Ecosystems

Vertical agriculture based on hydroponic technology is a form of resource efficiency that is in line with the principles of sustainable development. A report by the Food and Agriculture Organization of the United Nations (FAO) highlights that this system is able to save water by up to 90% through a closed circulation mechanism. In large cities that often experience clean water crises, this technology is the most rational technocratic answer for producing food hygienically.

A 30% higher harvest speed compared to conventional methods makes vertical agriculture a reliable production machine in the midst of high urban mobility. The public must be encouraged to adopt this technology not only for personal consumption, but as a new standard in residential environment management. Investing in vertical garden installations is an investment in the resilience of the city's green infrastructure.
