Thailand is one of the world's largest food exporters, shipping rice, cassava, sugar, tropical fruit and seafood, and is highly self-sufficient. Food import dependency is therefore low, so no import figure was needed to place it high.
Local staples
Rice, tofu, vegetables, chillies, herbs, tropical fruit and coconut, with fish and shrimp paste in most cooking.
Markets
Daily fresh markets, night markets and weekend and floating markets.
In season
Main rice harvest around November to December; tropical fruit such as durian and mangosteen April to June.
Wildlife

Thailand holds rich Indomalayan wildlife, including wild Asian elephants, hornbills, gibbons and one of Southeast Asia's most important tiger populations in the Huai Kha Khaeng and Western Forest Complex, where tiger numbers have recovered. Populations remain under trafficking and habitat pressure and endemism is moderate.
Found nowhere else
Limestone-karst species and endemic freshwater fish, plus the critically endangered Siamese crocodile and Gurney's pitta.
Natural phenomena
Cool-dry Nov–Feb, hot Mar–May, monsoon May–Oct — the islands vary coast to coast.
When to go
The cool, dry season, avoiding the June to October monsoon and the northern burning season.
Getting around
Trains, cheap domestic flights, buses and ferries between islands, with tuk-tuks and songthaews locally.
Good to know
Cash everywhere, cards in malls; THB. Remove shoes at temples; the monarchy is deeply revered.
Safety
Solo female travel: Easy. LGBTQ+: High.

Full assessmentHowever the pronounced wet and dry seasons bring both major flooding, as in 2011, and dry-season drought and saltwater intrusion, and tap water is not recommended for drinking even though basic access is near universal. |

Default cooking does lean on fish sauce and shrimp paste, so care is needed for strict plant-based diets. |
| OrganicCertified and chemical free growing, which is not the same thing as plant based | 2/5 | About 0.7% of agricultural land is certified organic (FiBL, 2020 data), though the country actively promotes organic jasmine rice for export. |
| ConservationWhat is protected, and whether protection is enforced | 3/5 | About 18% of Thailand's land is protected (World Bank, 2025), including national parks such as Khao Yai and the Western Forest Complex, but marine protection is limited at around 5%.

Territorial CO2 emissions sit at a moderate 3.74 tonnes per person (2024), below the world average. At COP30 in November 2025 Thailand brought its net-zero greenhouse gas target forward to 2050 from the previous 2065, alongside a pledge to cut emissions 47% by 2035 conditional on international support.
