The generally low-lying nature has exposed particularly the eastern parts of the coastal strip to intense sea erosion and occasional flooding. Notwithstanding, a great irrigation potential exists. The Coastal Strip is marked by sand bars with a few sea cliffs bordering the coast. This belt is affected by severe sea erosion, the previously worst hit areas include Keta, Kedzikope, Vodza, Kedzi and Horvi which have been saved by the Keta Sea Defence Project. Currently Srogboe-Dzita stretch is under severe sea erosion resulting in damages to properties and loss of livelihoods to about twelve communities which are periodically cut off during high tidal waves.

The general elevation of the lagoon basin is also below sea level. It is made up of lagoons and islands such as Atiavi, Alakple, Seva, Anyako and Dudu. The basin is generally marshy due to the underlying sandy-clay geological formation. The main drainage basins are the lagoons, which together constitutes about 362km². The major lagoons include Keta, Angaw Agbatsivi, Logui, Nuyi and Klomi. Into this basin drains some streams and distributaries of the Volta River. These include such streams as Angor, Avida, (near Hatorgodo), Awafla (near Awaflakpota), Nukpehui (in the north-western part of the Municipality), Tordzie and Kplikpa. Many of the creeks are dwindling in size due to low rainfall, excessive evaporation and siltation. As a result, the volume of water in the lagoon has drastically declined and tends to fluctuate seasonally, leading to the emergence of several islands in the Keta, Angor and Agbatsivi lagoons. The biggest among the Islands are Seva and Dudu, which are partially inhabited.

The Northern plain is generally gently undulating with a relatively higher elevation of about 50 metres above sea level.

The entire Municipality falls within the coastal savanna zone which is categorized into four (4) vegetational Zones.

• The northern part of the Municipality marked by tall grasses and interspersed with medium sized trees with relatively higher density.
• The mid-section of the Municipality with short grasses and short trees with occasional occurrence of “Pamira” palm and baobab trees.
• South-western part, characterized by mangrove plants along the Volta estuary and tall grasses used for fuel, and mat/hat weaving respectively.
• South-eastern part along the coast from Whuti with short grasses and many neem trees. Most of the coconut trees along the coast have been affected by the Cape St. Paul Wilt disease. This has had a major influence on the pattern of rainfall in the Municipality.

The municipality is a home to most of the Fauna that are extinct such as sitatunga, 15 families of finfish’s, Manatees, monkeys, African/Royal python, 3 species of marine turtles, crocodiles and  high diversity of bird species.

The Municipality falls within the Dry Coastal Equatorial Climate with an annual average rainfall of less than 1,000mm. The amount of rainfall reduces as one travels from the north to the coastal parts where only about 800mm per annum may be recorded. The Municipality is thus one of the driest along the coast of Ghana. The Municipality experiences a double maximum rainfall pattern. The major rainy season is between March and July while the minor one begins in September and ends in November. Thus the total amount of rainfall is relatively low. Hence all year round cropping is severely constrained and the vegetable farming around Anloga which depend largely on irrigation.

The high average temperatures (about 30^oC), couple with low relative humidity, promote high evapo-transpiration. The high evapo-transpiration also exacerbates the general water deficient conditions and a potential for salt production. The pattern shows a declining trend and the distribution over the year is highly uneven.

(i) Oyibi-Muni Association

Along the coastal strip are the Oyibi-Muni and Keta Associations characterized by sandy soils often without any top layer of humus. Naturally, it supports coconut cultivation. When manured, it supports shallot, okro, pepper and other vegetables. In fact, this strip is the leading shallot producing area in Ghana though it covers only about 11 per cent of the Municipality (excluding lagoons).

(ii) Ada-Oyibi Association

The Soil in the lagoon basin (Ada-Oyibi Association) is very shallow, overlying a hard and compact clay formation. The soil is generally alkaline and supports mangrove vegetation, sugar- cane, and grass for pasture. Due to the underlying clay, this area is liable to flood and not suitable for arable farming though it covers over 75 per cent of the total dry land of the Municipality.

(iii) Toje-Alajo Association

The Toje-Alajo Association covers the Northern plain around Abor and constitutes about 14 per cent of the Municipality (lagoon excluded). It is relatively deep and supports crops like cassava, maize and legumes.

Traditional Administration

Keta Municipality is part of Anlo Traditional Council which has 36 states and headed by a paramount chief, the Awoamefia of Anlo who serves as a symbol of authority among all people in the Municipality. There are other chiefs with their own areas of influence who assist the Awoamefia in the promotion of peace and stability in the Municipality. Every year in the first week of November, the people gather at Anloga to celebrate Hogbetsotso Festival. Display of rich cultural values, resource mobilisation for development and peaceful co-existence are prominent issues considered during the occasion.

 Religious Composition

The predominant religion is Christianity, which constitutes about 72.8 percent of the population followed by traditional religion 25.4 percent, Muslim 1.0 percent and others 0.8 percent. The fact still remains that Christianity dominates in the Municipality and some people practice it alongside traditional religion.

Ethnic Composition

The 2010 Population and Housing Census Report shows that the Ewes still dominate the Municipal population with about 98.7 percent while the other tribes constitutes the remaining 1.3 percent. This indicates that the population of the Municipality is highly homogeneous regarding ethnicity.

Festivals

The main festival is the Hogbetsotso, which symbolizes the great exodus of Ewes from their ancestral home, Notsie, to their present abode around the 15^th Century. The Hogbetsotso Festival, which is celebrated at Anloga, the traditional home of the Anlos, attains a grand final with a durbar of Chiefs and people amidst pomp and pageantry on the first Saturday of every November.
