Final answer:
The SADC (Southern African Development Community) does not protect farms in New Jersey as it focuses on southern Africa. Instead, sustainable agriculture systems support smallholder farms, which are generally smaller than two hectares, and promote practices like carbon sequestration.
Step-by-step explanation:
The question appears to be confusing two different topics. The acronym 'SADC' typically stands for the Southern African Development Community, which is an organization that aims to promote sustainable and economic growth among member states in southern Africa. It does not have a direct role in protecting farms in New Jersey. For New Jersey, there could be a program meant to protect farms, but it is unrelated to the SADC of southern Africa.
Regarding the concept of Sustainable Agriculture Systems, these are designed to support smallholder farmers who typically operate on farms smaller than two hectares. These smallholder farms are crucial for food security and income in many regions. They utilize family labor and focus on cultivating small areas of land, often utilizing practices that enhance carbon sequestration and increase the sustainability of agricultural practices.
Therefore, while the SADC does not directly protect farms in New Jersey, the principles of sustainable agriculture and supporting smallholders are universally important. Programs that aid smallholder farms and encourage sustainable practices contribute to food security and can help in mitigating climate change through carbon sequestration.
