Description of the study map and research project
The following map depicts the study area for a research project titled, Farmer perceptions of climate change and variability in villages adjacent to the Udzungwa Mountains National Park, Tanzania. This project takes place in three villages—Magombera, Mang’ula A and Msosa—in south central Tanzania. Magombera and Mang’ula A Villages lie to the east, and Msosa Village to the north west of the Udzungwa Mountains National Park. The park spans over 1,900 square kilometers and is one of only a few areas with protected status within the Eastern Arc Mountains of Tanzania, conserving and supporting biodiversity and endemism within the Eastern Afromontane Biodiversity Hotspot. These mountains are globally renowned for their high concentrations of endemic species and biodiversity (Bunting et al., 2011; Burgess et al., 2007) and stretch from the Taita Hills of Kenya, southward to the Mahenges of Tanzania (Dinesen, Lehmberg, Rahner, & Fjeldså, 2001). These forests are unparalleled in importance for the preservation of biodiversity and endemicity on the African continent (Dinesen et al., 2001; Topp-Jørgensen, Reinhardt Nielsen, Marshall, & Pedersen, 2009).
According to recent studies, these mountains are under increasing threat, resulting from the proximity of tens of thousands of smallholder farmers to the mountains (Burgess et al., 2007; Cordeiro et al., 2007; Harrison, 2006; Rovero, Mtui, Kitegile, & Nielsen, 2012). Should climate change shift the viability of local farming livelihoods, which support 96 percent of individuals in the area, it is likely that farmers will turn to the park for resources (Harrison, 2006).
This project aims to understand the environmental, agronomic, and climatic perceptions of smallholder farmers who live adjacent to the Udzungwa Mountains National Park. Considering the conservation value of this region, it is important to demonstrate how farmers here perceive environmental, climatic, and livelihood changes, to begin understanding potential future impacts and conservation-livelihood strategies. Increasing system resilience here will not only improve smallholder livelihoods, but also ensure future forest health. The following sections show a map of this area and provide brief descriptions of each of the study villages.
Magombera Village (Figure 2) lies at 36°, 56” east; 7°, 49” south on the Kilombero Floodplain in the Kilombero District of the Morogoro Region, just north of the Magombera Forest. This small forest is one of the last remaining tropical lowland forest fragments between the Udzungwas and the Selous Game Reserve, a protected area of exceptional conservation value in south-eastern Tanzania (Gillingham & Lee, 2018). Magombera Village consists of three small and isolated settled areas, interspersed with sparse vegetation, household bustanis (gardens) where vegetables are grown, and small houses constructed primarily of wattle and daub (stick frames plastered with mud) with thatched or corrugated rooves. Most villagers rely primarily on subsistence, rainfed agriculture as their primary livelihood strategy, though many partake in alternative strategies (e.g., livestock rearing, weaving, brewing) to supplement farming.
The village lies in the lowlands, allowing many farmers to grow rice on an annual basis. Elevation, human-made wetland rice paddies, and continuously saturated soils in some parts of Magombera Village provide an opportunity to grow rice throughout seasons when rice production is impossible in other nearby villages, attracting additional in-migrants to Magombera. Agroecologically, the village lies at the transition zone between rice and sugar cane. These crops are grown as monocultural stands in the large (> 1 acre) shambas (plots) that farmers keep on the outskirts of the settled areas. Many farmers are out-growers for the commercial Illovo Sugar Cane operation.
Mang’ula A Village
Mang’ula A (Figure 3) lies at 36o, 54” east; 7o, 50” south on the Kilombero Floodplain, directly to the east of the Udzungwa Mountains National Park entrance. The village is large, with one main settlement. The settlement consists of mostly homes, kitchens and latrines, many of which are made of brick or wattle and daub, occasionally covered stucco, with corrugated or thatched rooves. Many villagers rely on a mixed wage-subsistence livelihood, where farming is supplemented by other livelihood strategies that produce liquid assets (e.g., owning a small business, participating in microfinance schemes).
The village lies at the transition zone between rice, sugarcane and maize. Many fields are inundated and appropriate for rice production seasonally, during the long, masika, rains which occur from March to May, but some farmers own or rent land in the lowlands, where rice farming is appropriate all year.
Msosa Village (Figure 4) lies at 36° 31” east; 7°, 30” south on the northwestern edge of the UMNP. The village has two settlements. The first settlement lies to the west of the Great Ruaha River, and the second along the smaller Msosa River, both set back from the rivers’ edge by agricultural fields. The settlements are sparse, with very little vegetation, consisting mostly of homes made from fired or mud brick or plaster with corrugated or thatched rooves, latrines, kitchens, and communal, raised stalls for storing onions. Most villagers rely on farming as their main livelihood strategy, though many partake in alternative strategies (e.g., retail shops, livestock keeping) to supplement their livelihoods.
Msosa village experiences unimodal rains but relies on gravity and pump irrigation for farming. Unlike Mang’ula A and Magombera, however, villagers primarily grow crops to sell in major markets, not for subsistence use. Primary commodities include onions, beans, and ground nuts. Farmers often hold and store cash crops in communal storage facilities for sale during the thin months of April and May, when prices are higher and food supplies are low.
