The results of a study conducted by Dey and
Djumaty, show that there are various problems
experienced by the Dayak Indigenous People because
local wisdom such as farming by burning is
prohibited and until now there has been no concrete
solution provided by the Government so that the
Jurung/granary, that becomes a symbol of food
resilience, becomes empty (Dey and Djumaty, 2021).
This can make the Dayak Indigenous People
vulnerable to food crises.
3.2 Archipelago Food Diversity
Indonesia occupies the second position in the world
that has mega biodiversity after Brazil. However, if
all of Indonesia's biodiversity on land and at sea is
combined into one, it will occupy the first position
compared to Brazil (Hanum, 2020).
Reports from the Indonesian Institute of Sciences
show that Indonesia's biodiversity is recorded as
1,500 species of algae, 80,000 species of spore plants,
595 species of lichen, 2,197 species of ferns, 30,000-
40,000 species of flora, 8,157 species of vertebrate
fauna, 1,900 species of butterflies. The endemic fauna
species are 270 species of mammals, 386 species of
birds, 328 species of reptiles, 204 species of
amphibians, and 280 species of fish. The level of
endemic Indonesian flora is recorded between 40-
50% of the total flora species on each island except
for the island of Sumatra whose the endemic
estimated to be only 23%. The diversity of Indonesian
ecosystems is known to be around 74 types of
vegetation forming very complex formations
(Widjaja et al., 2015).
The biodiversity has been beneficial in terms of
health, renewable energy sources, ecosystem services
and food sources (Samedi, 2015). Sources of food are
divided into several types, namely carbohydrates,
animal and plant-based protein and food reserves
(Widjaja et al., 2014).
Indonesia has the potential of 5,529 types of food
crops, but only 100 carbohydrates sources, 100 types
of nuts, 250 vegetables and 400 types of fruits are
utilized (Arif, 2020). In contrast to the results of Arif's
research, based on a report from the Food Security
Agency of the Ministry of Agriculture, there are 77
types of carbohydrate sources, 26 types of nuts, 389
types of fruits, 228 types of vegetables, and 110 types
of spices and seasonings spread throughout
Indonesia. Widjaja et al, 2015). In addition, Pradipta
also added that food diversification in Indonesia
recorded about 400 varieties of fruit, 370 varieties of
vegetables, 70 varieties of tubers and 55 varieties of
spices (Pradipta, 2019).
Although the data regarding the types of food
plants in Indonesia is vary, but it can be concluded
that Indonesia has a diversity of food sources and the
habit of indigenous peoples in consuming various
foods that have been inherited since the time of their
ancestors. The diversity of food sources should be
able to meet national food needs. This potential
should be managed strategically to actualize national
food security based on food sovereignty and
independence.
Indonesia's local food diversity is reflected in the
food consumption habits of indigenous peoples. The
pattern of food consumption differs from one region
to another. This is influenced by various factors,
including land biotic conditions, food availability,
socio-culture, knowledge of nutrition, economy and
the environment (Banita, 2013; Suryana et al., 2014,
Warsilah, 2013).
In the context of the Tomun Lamandau Dayak
Indigenous Community, where the community's food
consumption pattern varies from planted crops, forest
products to food obtained from rivers. With so many
variants of food sources, the domestic food security
of Indigenous Peoples becomes stronger. If managed
properly and supported by policies that are right on
target, local knowledge about local food diversity
should be able to contribute to national food security
so that the concept of SDGs related to zero hunger can
be actualized.
Local knowledge of the Tomun Lamandau Dayak
Indigenous community about food processing in the
context of food sustainability will be discussed in the
points below.
3.3 Local Knowledge of the Indigenous
Dayak Tomun Lamandau about
Food Sustainability
Food security is a condition in which all people have
access to sufficient, safe and nutritious food to meet
their nutritional needs and food preferences for an
active and healthy life (Jagau et al, 2016). Based on
this, food security can be seen from several aspects,
namely food availability, food accessibility, usage
and stability, and also food quality.
The concept of food security is also contained in
the second point of the Sustainable Development
Goal (SDG) policy, namely ending hunger, achieving
food security, improving nutrition, and encouraging
sustainable agriculture. In the context of food security
and sustainability, it has actually been practiced by
indigenous peoples in the territory of Indonesia,
where people recognize the concept of food diversity
in their daily lives.
