Measuring the Technical and Scale Efficiency of Maize Production in Thailand: The Case of Mae Chaem District, Chiang Mai

This paper aims to measure the technical efficiency(TE) by identifying sources it for maize production in Mae Chaem District, Chiang Mai, Thailand and to explain estimated TE by farmer characteristics. Data Envelopment Analysis was employed to estimate farmer (DMU) score of technical efficiency both of the constant return to scale (CRS) and the variable return to scale (VRS) were applied to the study based on input oriented, a relative efficiency index in production. Then, Tobit regression model was used to clarify the variation in technical efficiency scores by determining major farmer’s characteristics as an element factors behind. A total 103 Maize farms were selected for the study dividing into 2 groups by 52 farms were non-burn farm and 51 farms were burned farm. The result showed that group1 has more average efficiency than group2 by 7% under the constant return to scale and 1% under the variable return to scale. The scale efficiency result show that majority of both of farmer group were operated with increasing return to scale. Tobit regression result shows that farm’s characteristics such as farm experience, burn, family size have statistically significantly affected by 0.53, -7.2 and 1.36 percent to technical efficiency under constant return to scale, the technical efficiency under variable return to scale was influenced by farm experience and family size by 0.61 and 1.10 percent respectively.

Conservation and Endangered African Wild Dogs (Lycaon pictus) in Western Tanzania: A Call for Research and Action

The African wild dog is among the most endangered carnivores. Yet, the remaining populations are small and patchily distributed as a result of factors like human persecution, poaching, diseases, habitat loss, loss of prey and competition from other predators. Regrettably, research has paid little attention to the effectiveness of local conservation measures in tackling these challenges in some small wild dog populations especially in east African ecosystems. This paper focuses on the Ugalla ecosystem of western Tanzania as it outlines the pressing conservation need to conduct research and explore the influence of anti-poaching patrols and participatory conservation on the prey abundance and habitat availability for African wild dogs. Wildlife poaching in Ugalla is likely to bring about local prey depletion. Furthermore, unsustainable agricultural practices, illegal settlements and logging are important causes of wildlife habitat loss. There is a critical need for wildlife researchers to address these challenges and put forth handy recommendations in the context of anti-poaching measures and participatory conservation owing to the urgency of wild dog protection and the fact that the species is wide-ranging

Toward effective partially protected areas in Tanzania: a review on experiences from Ugalla ecosystem

Tanzania is understandably concerned about the deterioration of its partially protected areas (PPAs, e.g. game controlled and open areas) due to unauthorised resource use activities. Its 2007 wildlife policy recognises that PPAs are managed as buffer zones so they provide a cushion against land use impacts on core protected areas, and support local livelihoods. Ensuring effective protection of PPAs is especially timely given the fact that Tanzania’s human population is now large and growing rapidly, with rising demand for natural resources, and that protected areas are becoming increasingly isolated. This paper draws insight from research activities in Ugalla ecosystem, western Tanzania, to draw attention to the threats facing PPAs in the country, and discuss strategies for addressing them. Ugalla ecosystem consists of Ugalla Game Reserve and the surrounding vast PPAs that experience logging, poaching, forest invasions, and pressure from other livelihood activities.  Consequently, wildlife populations are contracting and habitats are quickly disappearing. Law enforcement, participatory conservation and improving household livelihoods are key to effective deterrence of unauthorised activities; increasing access to family planning services would enable people to better manage the size of their families, and thus ease pressure on resources due to the growth of local populations; community outreach and engagement would help win local support for conservation; effective wildlife management areas would benefit both local community and conservation; monitoring is critical to informing conservation actions; introducing some strict protectionism would slow persistent offtake. Lastly, local conservation authorities should be supported to address the underlying causes of conservation problems in the PPAs.Keywords:     partially protected areas, unauthorised activities, impacts, interventions, Ugalla, Tanzani
