Expanding and promoting democracy is an objective trend of social progress. In the process of leading the Vietnamese revolution, the Communist Party of Vietnam has always valued and promoted the people’s mastery, relying on the people to bring Vietnam’s revolution from one victory to another. Especially now that Vietnam is in the process of renewal, accelerating industrialization and modernization, and strengthening regional and international integration, the Communist Party of Vietnam continues to clearly show its great role in expanding and Enhancing democracy will contribute to raising Vietnam’s position in the international arena, meeting the country’s requirements and requirements in the new period.

Assess to quality diets is a basic human right. Geographical challenges and cultural traditions have contributed to the widespread malnutrition present among ethnic minorities of mountainous areas in Northwest Vietnam. Home gardens can play a role in increased diet diversity and micronutrient intakes. However, low production yields and plant diversity in ethnic home gardens have limited their contributions to household food security and nutrition. The pilot study tested a home garden intervention in weekly vegetable harvests and increasing household production and consumption of diverse vegetables year-round. Food ethics issues encountered included limited access to quality food by resource-poor groups, conflicts arising from low preference and value given to some nutritious foods, limited access to information and technology for food production and consumption, each of which were addressed in the study design. The intervention includes: (1) nutrition-focused home garden training and (2) locally-adapted home garden packages consisting of garden planning, technical assistance, and high-yielding seed varieties. Twenty households from two ethnic villages in Son La province participated in the study and were randomly assigned into two groups (intervention and non-intervention). The total vegetable supply from weekly harvests of home garden produce was significantly higher in the intervention households (226 kg) compared to the non-intervention households (39 kg). The intervention group yielded 5.8 and 1.7 times more vegetables by weight and weight per area than those without the intervention. The vegetables were mainly consumed at home for both groups, but the intervention households gave more vegetables as gifts to neighbors. The intervention group cultivated a higher diversity of vegetables with a total of 42 different vegetables compared to 24 in the non-intervention group, which is reflected in an overall higher nutritional yield of vitamin A, iron, other micronutrients and phytochemicals. The home garden training significantly improved the amount, diversity and continuity of household food and nutrient supply. The home garden model is effective and could be scaled up to improve household vegetable supply and consumption, particularly in Northwest Vietnam.

This chapter explores the potential of Northwest Vietnam to diversify its land use through vegetable production systems. Temperate vegetables such as tomato and common cabbage have a high potential for Northwest Vietnam because of its relatively cool climate and these products offer the opportunity to reduce reliance on imported temperate vegetables. Constraints and opportunities for Northwest Vietnam to expand vegetable production were evaluated by focusing on the representative provinces of Son La and Dien Bien and their potential to supply fresh produce to the urban markets of Hanoi. Data from producers and consumers was analyzed for changing trends. In addition, on-farm trials were conducted to determine the suitability of introducing elite vegetable varieties and integrated pest management options into existing farming systems. The use of integrated pest management is particularly important because Hanoi consumers associate vegetables from the Northwest with low levels of pesticide use.
