Independent Study Project (ISP) Collection

Madagascar has one of the highest concentrations of palm diversity in the world, with 195 species, 192 of which are endemic, but just as for the rest of the island’s natural resources, the future of these palms is at stake. In fact, 83% of the country’s endemic palms qualify as threatened following the most recent version of IUCN Red List criteria, version 3.1, yet 28 are not even found within protected areas. One area awaiting government protection, MBG’s Pointe à Larrée project, is home to 18 different palm species, 11 of which are threatened. This study took sample counts to …

Comparison Of Coral Reef Health: Lokobe National Park And Tanikely National Park, Northwest Madagascar, Kailani Acosta

Independent Study Project (ISP) Collection

Coral reefs are microcosms of biodiversity and life. They are home to about a quarter of all marine life, yet amount to only about 1% of the world’s marine environment. Coral reefs are very vulnerable ecosystems; there are numerous threats to their health, such as damage by echinoderm and fish feeding, natural disasters, coral illness and bleaching events. Coral health fluctuates according to many of these factors and as a result of the fragile symbiotic balance between zooxanthellae algae and corals. Subsequently, coral health is an essential topic for analysis and assessment.

Coral reefs were assessed in Lokobe National Park, …

Micro-spatial habits showed to have weak to no effect on all measured physiognomic variables giving insignificant p-values according to ANOVA. However, correlation tests against leaf litter depth and slope showed to have some relation to the size and …

Land Rights Among Subsistence Farmers: An Examination Of Madagascar’S Land Reform And Prevailing Systems Of Land Tenure In Betafo, Taylor Crowl

Independent Study Project (ISP) Collection

In Madagascar, legal systems of land tenure have been inaccessible for the vast majority of the rural population. This has stranded millions of subsistence farmers in a sense of insecurity, as they lack legal rights for the property that they have farmed for generations. Madagascar’s land reform, launched in 2005, attempted to change these exclusionary tenure practices. This reform —known as the Plan National Foncier—created land certificates and local land offices in an attempt to make legal land tenure financially, geographically, and logistically accessible to the local population. This study discusses the successes, failures, and unforeseen consequences of Madagascar’s land …

The Mechanical And Social Feasibility Of Using Biogas To Fuel An Essential Oil Distillation Unit In The Rural Commune Of Ankarimbelo, Madagascar, Hannah Nesser

Independent Study Project (ISP) Collection

The rural commune of Ankarimbelo is located on the edge of the Ikongo Rainforest Corridor in southeastern Madagascar. The commune’s remote location, an increasing population, and the prohibition of farming in the rainforest corridor have contributed to extreme poverty. In an attempt to mitigate these effects, the Malagasy NGO Ny Tanintsika has implemented an essential oils distillation plant as an alternative livelihood project. While the project may provide needed income to local populations, thereby diverting destructive agriculture practices such as tavy, or slash-and-burn agriculture, the distillation of essential oils still requires that firewood be burned. Over the course of …

The Optimal Foraging Of Equus Burchelli At Enashiva Nature Refuge, Edward Haubenreiser

Independent Study Project (ISP) Collection

Within the country of Tanzania lies a vast ecosystem known as the Serengeti. This unique landscape, primarily of grasslands and woodlands, shapes the seasonal feeding habits of the abundant wildlife that call the area home. While these feeding habits on a large spatial scale are well understood, such behavior within a specie’s specific environment remains of interest. With the theory of optimal foraging in mind, which considers how animals should look for and select food (Green, 1990), I studied the foraging habits of resident Burchell’s zebra (Equus burchelli) by observing if they move and forage among distinct resource …

The Conceptualization Of “Environmentalism” In Sagara, Emma Chapman

Independent Study Project (ISP) Collection

My study focused on the perceptions of “environmentalism” in Sagara, Tanzania and attempted to compare Sagaran concepts to those of a more Western model. My study also identified the “actors” that taught Sagarans about the environment. After finding that Sagarans held a strong resource conservation focus in their responses, I then focused on the details of their resource use to see whether what they have been taught about conservation has been actualized in their daily life. I predicted to find that Sagarans have a much more generalized and resource conservation focused definition of “environmentalism” and that their patterns of resource …
