**6.3 National legislature to safeguard agrobiodiversity particularly of TAV**

Tanzania is one of the twelve mega-diverse countries of the world endowed with different natural ecosystems that harbor a massive wealth of biodiversity [49]. By then, the country hosted 6 out of the 25 world renowned biodiversity hotspots hosting more than one-third of the total plant species on the continent and about 20% of the large mammal population [49]. In Tanzania, the Biodiversity wealth contributes significantly to the socio-cultural, economic and environmental goods and services to the country and peoples` livelihood. The public policies, market dynamics, wholesale and retail distributors in agriculture have led to legislation of varietal registration and seed quality, and for supporting the increase in productivity. The legislation has conditioned agriculture, shifting it towards specialization and monoculture. This decreases diversity in farming methods. This review recommends for developing legislative mechanisms to support conservation of genetic biodiversity under in situ and ex situ conditions through the establishment of field gene banks and cryopreservation centres and establish a mechanism for capacity building, participation

and empowerment of farmers through legislative measures for conservation and utilization of such genetic resources.
