Jack Oyugi is an entrepreneur from Kenya known for developing Aquaprotein animal feed from water hyacinth, an invasive species in Lake Victoria. [1] [2] [3]
Oyugi worked as a dairy farm manager and observed that water hyacinth would be consumed by cows up to the point where it became inundated with heavy metals. In 2016, he started a company which harvested hyacinth and processed it with a fungus to increase protein levels from 14% to 50% to create a product able to be used as feed. [4] [5] Fishermen on Lake Victoria harvest the hyacinth. The byproduct can also be used as fertilizer. [3]
The Geography of Kenya is diverse, varying amongst its 47 counties. Kenya has a coastline on the Indian Ocean, which contains swamps of East African mangroves. Inland are broad plains and numerous hills. Kenya borders South Sudan to the northwest, Uganda to the west, Somalia to the east, Tanzania to the south, and Ethiopia to the north. Kenya currently faces border disputes with South Sudan over the Ilemi Triangle and with Somalia over Jubbaland where, if the Somalian Government gives it up, it could be a new part of Kenya, which would bring the total land area of Kenya to approximately 692,939 km2.
Lake Baringo is, after Lake Turkana, the most northern of the Kenyan Rift Valley lakes, with a surface area of 130 square kilometres (50 sq mi) and an elevation of 970 metres (3,180 ft). The lake is fed by several rivers: the Molo, Perkerra and Ol Arabel. It has no obvious outlet; the waters are assumed to seep through lake sediments into the faulted volcanic bedrock. It is one of the two freshwater lakes in the Rift Valley in Kenya, the other being Lake Naivasha.
Lake Victoria is one of the African Great Lakes. With a surface area of approximately 59,947 km2 (23,146 sq mi), Lake Victoria is Africa's largest lake by area, the world's largest tropical lake, and the world's second-largest fresh water lake by surface area after Lake Superior in North America. In terms of volume, Lake Victoria is the world's ninth-largest continental lake, containing about 2,424 km3 (1.965×109 acre⋅ft) of water. Lake Victoria occupies a shallow depression in Africa. The lake has an average depth of 40 m (130 ft) and a maximum depth of 80–81 m (262–266 ft). Its catchment area covers 169,858 km2 (65,583 sq mi). The lake has a shoreline of 7,142 km (4,438 mi) when digitized at the 1:25,000 level, with islands constituting 3.7% of this length.
The Nile perch, also known as the African snook, Goliath perch, African barramundi, Goliath barramundi, Giant lates or the Victoria perch, is a species of freshwater fish in family Latidae of order Perciformes. It is widespread throughout much of the Afrotropical realm, being native to the Congo, Nile, Senegal, Niger and Lake Chad, Volta, Lake Turkana, and other river basins. It also occurs in the brackish waters of Lake Maryut in Egypt. The Nile perch is a fish of substantial economic and food-security importance in East Africa. Originally described as Labrus niloticus, among the marine wrasses, the species has also been referred to as Centropomus niloticus. Common names include African snook, Victoria perch, and many local names in various African languages, such as the Luo name mbuta or mputa. In Tanzania, it is called sangara, sankara, or chenku. In Francophone African countries, it is known as capitaine. Its name in the Hausa language is giwan ruwa, meaning "water elephant".
Lake Kyoga or Lake Kioga is a large shallow lake in Uganda, about 1,720 km2 (660 sq mi) in area and at an elevation of 1,033 metres. The Victoria Nile flows through the lake on its way from Lake Victoria to Lake Albert. The main inflow from Lake Victoria is regulated by the Nalubaale Power Station in Jinja. Another source of water is the Mount Elgon region on the border between Uganda and Kenya. While Lake Kyoga is part of the African Great Lakes system, it is not itself considered a great lake.
Lake Turkana is a saline lake in the Kenyan Rift Valley, in northern Kenya, with its far northern end crossing into Ethiopia. It is the world's largest permanent desert lake and the world's largest alkaline lake. By volume it is the world's fourth-largest salt lake after the Caspian Sea, Issyk-Kul, and Lake Van, and among all lakes it ranks 24th.
The African Great Lakes are a series of lakes constituting the part of the Rift Valley lakes in and around the East African Rift. The series includes Lake Victoria, the second-largest freshwater lake in the world by area; Lake Tanganyika, the world's second-largest freshwater lake by volume and depth; Lake Malawi, the world's eighth-largest freshwater lake by area; and Lake Turkana, the world's largest permanent desert lake and the world's largest alkaline lake. Collectively, they contain 31,000 km3 (7,400 cu mi) of water, which is more than either Lake Baikal or the North American Great Lakes. This total constitutes about 25% of the planet's unfrozen surface fresh water. The large rift lakes of Africa are the ancient home of great biodiversity, and 10% of the world's fish species live in this region.
Kisumu is the third-largest city in Kenya located in the Lake Victoria area in the former Nyanza Province. It is the second-largest city after Kampala in the Lake Victoria Basin. The city has a population of slightly over 600,000. The metro region, including Maseno and Ahero, has a population of 1,155,574 people according to the 2019 Kenya Population and Housing Census which was conducted by the Kenya National Bureau of Statistics.
The Mesker Park Zoo and Botanic Garden is a zoo that opened in 1928 in Evansville, Indiana, United States. It is located in Mesker Park on Evansville's northwest side and is run by the City of Evansville.
Lablab purpureus is a species of bean in the family Fabaceae. It is native to sub-Saharan Africa and India and it is cultivated throughout the tropics for food. English language common names include hyacinth bean, lablab-beanbonavist bean/pea, dolichos bean, seim or sem bean, lablab bean, Egyptian kidney bean, Indian bean, bataw and Australian pea.

Kwan Phayao is a lake in Phayao Province, northern Thailand. Kwan, a word from the northern Thai language, means 'lake' or 'large swamp'. The shape of the lake is a nearly-half-circle-moon shape. Phayao Lake is the largest freshwater lake in the northern region and the fourth largest in the country, with a depth of 1.5 metres, and covers an area of about 1,980 hectares. There are about 50 species of fish in Phayao Lake.
The African fish eagle or the African sea eagle is a large species of eagle found throughout sub-Saharan Africa wherever large bodies of open water with an abundant food supply occur. It is the national bird of Malawi, Namibia, Zambia, and Zimbabwe. As a result of its large range, it is known in many languages. Examples of names include: Vis Arend in Afrikaans, nkwazi in Chewa, aigle pêcheur in French, hungwe in Shona, inkwazi in isiZulu, and ntšhu in Northern Sotho. This species may resemble the bald eagle in appearance; though related, the two species occur on different continents, with the bald eagle being resident in North America.

Environmental issues in Kenya include deforestation, soil erosion, desertification, water shortage and degraded water quality, flooding, poaching, and domestic and industrial pollution.
Pontederia crassipes, commonly known as common water hyacinth, is an aquatic plant native to South America, naturalized throughout the world, and often invasive outside its native range. It is the sole species of the subgenus Oshunae within the genus Pontederia. Anecdotally, it is known as the "terror of Bengal" due to its invasive growth tendencies.
Tourism in Kenya is Kenya's third largest source of foreign exchange revenue, following diaspora remittances and agriculture. The Kenya Tourism Board is responsible for maintaining information about tourism in Kenya.
Water hyacinth has become a major invasive plant species in Lake Victoria and while it is native to the continent of South America, human activity has introduced the greenery to Lake Victoria, where it is claimed to have negatively affected local ecosystems.
Climate change is posing an increasing threat to global socioeconomic development and environmental sustainability. Developing countries with low adaptive capacity and high vulnerability to the phenomenon are disproportionately affected. Climate change in Kenya is increasingly impacting the lives of Kenya's citizens and the environment. Climate change has led to more frequent extreme weather events like droughts which last longer than usual, irregular and unpredictable rainfall, flooding and increasing temperatures.
Yele Mallappa Shetty Lake is one of the largest lakes in Bangalore, located on the eastern side of the city, outside of KR Puram. It is an artificial water reservoir constructed in early 1900s. The lake is spread over 490 acres (198.3 ha).
The Yala River is a river in western Kenya, a tributary of Lake Victoria. It generally flows fast over a rocky bed through a wide valley before joining the Nzoia River to form the Yala Swamp on the border of Lake Victoria. The land along its course is mostly cultivated or used for grazing, with relatively few remnants of the original forest. Soil erosion is visible throughout the river basin, particularly in the lower parts. Projects are underway to exploit the river for hydroelectricity.
