">DATE Africa > Nyumba > Nyumba Infrastructure ←You are here Nyumba is the least populated and least densely populated country in the region. The limited infrastructure is significantly degraded. Most of the population and development is concentrated along the Tana and Juba Rivers, and the Indian Ocean ports of Lamu and Kismaayo. Paved roads are limited to the main artery running from Moyale in the north to Isiolo on the Amari border, and a 150 km strip from Kismaayo running northeast to Jilib.
Nyumba has the least developed infrastructure in the region. It is only partially connected to regional infrastructure networks. The exception is the northern portion of a transcontinental road corridor that connects southern Africa with the Red Sea. It depends entirely on imported electricity and refined petroleum. Despite its poverty and lack of development, in most years Nyumbans have access to sustainable water resources.

Kismaayo (Population: 235,000, Density: 5,595/km2)
Nyumba’s capital city and principal port, Kismaayo, is located on the Indian Ocean coast. It sits on a low hilltop overlooking the port to the south. The city center has a moderate building density of dilapidated colonial mid-rise buildings surrounded by organized shantytown construction.
Residential Features.
Beyond the dense random waterfront development, organized settlements are divided between directional grid and dense random construction patterns with few outward signs of affluent neighborhoods. Most residences are single story, densely packed dwellings with either concrete or dirt floors, mud walls, and corrugated metal roofing. Improved sanitation is mostly limited to public buildings and guesthouses. Electricity comes from one of two concessionaires using diesel generators and makeshift powerlines.
Commercial Features.
Kismaayo’s port has made it Nyumba’s main trading center. Livestock and charcoal are the main exports, and sugar is the main import. Commercial enterprises are mainly freight forwarding companies and a modest fishing fleet.
The main commercial strip runs along the city’s primary road, most heavily developed on the west side between the city center and the airport. Kismaayo has a functional market, banks, internet connectivity, filling stations, restaurants, and hotels. Government building construction is similar to the Ziwan capital of Musoma.
Garissa (Population: 119,696, Density: 1,361/km2)
Garissa is the second largest city in Nyumba and borders Amari on the Tana River. Local government maintains close ties to Amari due to trade and a growing electrical power interchange. A 3 km2 quadrant in the northern section of the city is the most developed, bordered by the river valley to the west, and the main highway to the east. Less dense development continues beyond this quadrant. Spacious residential properties make up Garissa’s southern section, separated from quasi-dense random residences to the east by the city’s airport.
The main commercial strip runs for 4 km along the highway south of the city center. Besides livestock and agricultural facilities, the area is also home to many government and educational institutions.
Lodwar (Population: 55.006, Density: 3.039 /km2)
Lodwar is the main city in remote northwest Nyumba. It sits on the junction of the A1 highway linking north central Africa with points south and the main road to the western shore of Lake Turkana. Lodwar is a key node in the planned LAPEX project. The city straddles the Turkwel River with most development on the north side of the river. A dry riverbed confluence forms Lodwar’s north and east boundaries.
Regional government, Lake Turkana tourism and support services make up the bulk of Lodwar’s development. Basic health, education, banking, and hospitality facilities are available. The city 0.6 km2 city center surrounds the road junction in a dense random construction pattern.
Isiolo (Population: 40,153, Density: 1,940/ km2)
Isiolo sits 10 km north of the Amari border on the main north-south Trans-African Highway along the east bank of the Isiolo River. 30,000 square kilometers of government and private nature reserve surrounds the city. It is also the proposed site of a significant LAPEX oil refinery/terminal complex and rail yard.
The city center is a .05 km2 closed block urban core straddling the main road in the city center. Most multi-story buildings are hotels or office buildings and are less than four levels. A 1.5 km commercial strip runs along the highway just south of the core. The rest of Isiolo’s development is randomly arranged to the west of the core and commercial strip. It extends approximately on half kilometer.
There are two significant compounds within the city limits. A 46 acre retreat-style complex sits east of the commercial strip between the highway and the town’s unpaved airport. A 500 acre security cantonment is 2.5 km east of the city center. Samburu, the largest of the nature reserves to the northwest, has two 2,500 ft+ airstrips, the southerly being paved.
Lamu (Population: 21,736, Density: 3,105/km2)
Lamu is a small port city on the southern coast of Nyumba, 75km by road to the Amari border town of Garsen and 40 km by air and sea to the coastal boundary. The main population center is on the eastern side of a 50 km2 island in the center of a coastal wetland archipelago. Lamu Island has a modest fishing industry, and exclusive eco-tourist enterprises.
Currently, most of the city’s 21,000 inhabitants live in the old city of Lamu, a .65 km2 dense random complex of narrow multistory buildings constructed in the 19’th century. Lamu prohibits motor vehicles because of the city’s narrow streets and historic status. An equally dense, but less restricted quarter is south of the historic district.

Transport Architecture
Roads
Nyumba has the least developed and maintained road network in the region. The north and central regions are connected with their neighbors to the north and south, but eastern and coastal Nyumba are more remote. The single paved regional highway is only paved west of Garissa. Little of the eastern road network is paved and many communities are only connected by tertiary roads or tracks.

Rail
Nyumba has no active railroads. A planned SGR railroad would connect northwest Nyumba with Lamu as part of the LAPEX initiative. Another would connecting Isiolo with Moyale following the general path of the Trans-Africa Highway.
Aviation
Nyumba’s only international airport is Kismaayo International (HCMK). Wajir Airport (HKWJ) in central Nyumba is the only other airport with a paved runway over 5,000 ft. There are 18 more serviceable airfields with runway lengths between 5,000 and 2,450 ft.
Nyumba has no national air carrier. Intercontinental and regional carriers have weekly flights to Kismaayo via Nairobi. Occasional intercontinental charter flights also make use of Kismaayo and Wajir. Fixed based operator services are limited to basic fuel and provisioning. Ziwan or Amari operators provide most charter service in Nyumba.
Facilities. See attached link for specific runway data.
Maritime
Nyumba has one major port in Kismaayo, with the smaller fishing port of Lamu under consideration for significant expansion. (link to Lamu port development page) It has a coastal fishing fleet but no merchant marine.
The port of Kismaayo was last modernized in the 1980’s and most of its facilities are in disrepair. Modest breakbulk commerce consists of sugar imports and charcoal exports on coastal traders. Ships must provide their own cargo handling equipment.
Petroleum Pipeline and Storage
Nyumba has no pipeline systems. Kismaayo and Wajir have limited AVGAS and Jet-A storage to support regularly scheduled air service. Diesel and gasoline stocks are limited to retail storage at service stations along the major highways. Tanker trucks supply these stations. Kismaayo has a modest tank terminal to support product deliveries at the port.
Pollution
The environmental impact of mine tailings is beginning to get international attention. Toxic runoff includes cyanide, arsenic, and mercury compounds used to extract trace amounts of gold from ore. The settling ponds are often close to the great lake watersheds.
Some international watchdog groups are sounding the alarm regarding water pollution in Lake Victoria. The two main sources are untreated sewage and fertilizer runoff. The combination is increasing the toxicity of the lake water and reducing the oxygen content, which in turn is devastating the fisheries.
Lake Victoria also suffers from a proliferation of non-native invasive species, particularly large Nile Perch. These fish are a significant source of revenue and sustenance for local fishermen, but have decimated native fish stocks and threaten the lake’s water chemistry.
