 Paig production is a dynamic and rapidly expanding livestock sector in Uganda and Vietnam, driven by a myriad of factors. Notably, the rising demand for pork, a typical Vietnam is, consumes some 25 kilograms of pork per year, while a Ugandan consumes nearly 4 kilograms of pork per year. In both countries, pig production is largely informal with the majority of pigs raised under a small holder backyard system. It provides livelihood to 8 million Vietnamese households and 1.1 million Ugandan households, contributing at least a quarter of income that households generate from livestock. The pig sectors of both countries are similar in structure, though the Vietnam sector is quite advanced with a population of pigs 10 times that of Uganda and a per capita consumption 7 times that of Uganda. Pork is generally procured in wheat markets. Fresh pork is the most preferred form of pork product among consumers in both countries. There is a small but growing demand for processed pork products sold in modern outlets in urban areas. We present the two case studies comparing the contribution of small holder pig production in pork supply using a multi market model framework. The case study is, will showcase a contribution and competitiveness of small holder pig production systems and their growth trajectories under various policy scenarios. We apply a partial equilibrium model to simulate the evolution of the small holder pig sector over time and highlight key drivers and their policy implications. By applying the multi market model framework in the pig sector of both countries, we generate evidence to answer a series of questions. But notably among them is how will shifts in pork demand influence pig producers, particularly small scale producers that is to say, will small scale pig producers be squeezed out of the market? The model has several characteristics. It's a partial equilibrium model that focuses only on maize and pig sector. It does not capture all other sectors in the economy. It's partial in that it simulates markets in eight regions of Vietnam and five in Uganda. It is reclusive dynamic in that it simulates over 10 years with growth in income, population and production technology. The model covers for commodities. Maize, fresh pork sold in rural markets produced by traditional producers. Fresh pork sold in urban, peri-urban wet markets produced by commercially oriented producers. And processed pork sold in former market outlets including supermarkets produced by large modern producers. Nine policy scenarios were simulated as follows. One, a baseline scenario. Two, where there is higher per capita income growth. Three, where there is no technology growth in the traditional pig sector. Four, where there is higher technology growth in the traditional pig sector. Five, where there is higher technology growth in both commercial and modern pig sector. Six, where there is no technology growth in the maize sector. Seven, where there is higher income elasticity for commercial and modern pork products. Eight, where there is higher income elasticity for products of and higher technology growth in commercial and modern pig sector. And lastly, the worst case scenario for traditional pig sector where there is zero technology growth. These were the key findings. In Uganda, traditional pig sector will retain dominant market share in fresh pork market except in worst case scenario of no technology growth in traditional sector. In Vietnam, traditional pig sector will maintain dominant market share in fresh pork markets. Modern pig sector captures dominant market share for fresh pork under scenarios of higher technology growth and income elasticity for commercial and modern pork products and in worst case scenario of no technology growth in traditional sector. These are the policy implications. Polices to foster productivity growth in the commercial oriented pig sector will increase their market share without squeezing out the traditional pig sector. Technology breakthroughs that will benefit all will be preferable for developing the pig sectors in these countries. We will conclude by pausing a couple of questions. Question one, does the approach taken that is the use of multi market and partial equilibrium model adequately address the research inquiry? Question two, do the findings lead to actionable policy insights?
