Spatial Analysis
The district space economy is understood by analyzing the existing settlement patterns and the spatial linkages.  This provides an insight into the functions performed by settlements and their hierarchy which the centrality indices are used to assess.

The population distribution by settlement is as shown in figure…………….
Some of the relatively larger settlements with population threshold of 350 plus was used to develope a scalogram as shown in figure……….. A scalogram is a matrix presentation of the functional structure of settlements.  These settlements provide essential services to themselves and their respective trajectory areas.

Location And Distribution Of Services
This deals with the type of number and distribution of facilities and services within the district.  It also aims at assessing the adequacy of these facilities and services and identifies the disadvantaged areas.  A critical look at the map showing the distribution of services, figure………..shows that most of the services are of lower order and as such the settlement spheres of influence are limited to their immediate surroundings.

Scalogram Analysis
The hierarchy of settlements has been determined by reference to the districts population size and the functional classification and centrality of settlements based on types of services available.  The functions and settlements were ordered in their rank of importance starting with the most abundant function and the settlement, which has the most facilities.

The next step was to compute the centrality index for each function.  This was done by dividing a score of 100 by the number of times this function is actually present in the district e.g. widely available function like traditional healer earns a low score while scarce function like hospital earns a high score of 100.  The centrality score for each settlement was then summed up.

Based on the summation, the settlements were then put into categories (orders) of levels 1, 2, 3 and 4.  level 1, are those with total functions of 65 percent and above, level 2 are those with 50 percent of total functions, level 3 are those with 40-49 percent and level 4 are those below 40 percent of total functions or services.

Table……….shows the existing hierarchy of settlements
The analysis revealed that majority of the settlements lack most of the basic functions such as potable water, electricity and health facilities and had to depend on other settlements.  Half Assini and Elubo occupy level 1 position with Tikobo No. 1 and Bonyere occupying level 2 position.  Level 3 position, is taken by Jewi Wharf and Tikobo No. 2 thus more than two-thirds of settlements in the system occupy the fourth position showing the unbalanced distribution of the central functions and services.

Levels of Spatial Development
A further analysis based on the scalogram, identified five steps/levels of development around Half Assini, Elubo, Tikobo No.1 & 2 and Bonyere with Half Assini and Elubo occupying level 1.

This shows a disintegrated spatial development as the district shows pockets of moderately developed few areas surrounded by a vast number of deprived areas. A concerted effort from the Assembly and the local communities is therefore necessary to upgrade some settlements.

Accessibility Analysis
This analysis was carried out in order to determine the ease with which people from different locations within the district can enjoy certain services located in other parts of the district. It enables the measurement of over-utilisation or otherwise of a service. For the purpose of this analysis, five services were selected having in mind their relative importance in meeting the basic needs of the people in the district. They were: -
1)    Periodic Markets
2)    Health Services
3)    Postal Service
4)    Education Service
5)    Agricultural Extension Service
 In determining the accessibility to these functions, the following assumptions were made based on the observed speed on the various modes of transport.

Observed Speed
Secondary Trunk Road             - 60 km/hr
Third class Road                       - 40 km/hr
Bicycle                                          - 15 km/hr
Walking                                        -   6 km/hr

Waiting Time
Secondary Trunk Road                -   1 hr
Third class Road                           -   2 hrs
River Transport {Jewi Wharf to communities along the Dwenye lagoon}                                                                                               - 1 hr. Using these assumptions, accessibility zones were determined for these services.

Periodic Market Service Linkage
Six Periodic Markets are very active in the district. These are Elubo, Jaway Wharf, Tikobo No.1 & 2, Sowdadzem and New Kabenlasuazo markets. Goods traded in these markets are mainly agricultural produce from the catchment area, and manufactured goods largely imported from outside the district. The catchment areas differ in size with Elubo, Jaway Wharf and Tikobo No.1 catchment areas extending beyond the boundaries of the district to other parts of the country and La Côte d’Ivoire.

 Health Service Linkage
There is only one hospital located at Half Assini and three health centers at Elubo, Ekabeku and Tikobo No.1. Cases from the health centers and other parts of the district are referred to the Half Assini Hospital or elsewhere outside the district. In effect the hospital caters for the whole district.

Postal Service Linkage
There are Five Post Offices at Half-Assini and Bonyere and five postal agencies at Nzimintianu, Ahobre, Elubo, Tikobo No.1 and Mpataba. Mails collected from the postal agencies are sorted out at the post offices before transporting them to Takoradi. The Half-Assini post office is the district headquarters and therefore has administrative jurisdiction over the rest.

Education Service Linkage
There are two public senior secondary schools in the district located at Half Assini and Ezinlibo respectively. There is a third, a private one at Mpataba.

 Agricultural Extension Service Linkage
Extension Officers located at Half Assini, Mpataba, Bonyere, Tikobo No.1&2 and Elubo serve the district. The District Office at Half-Assini supervises these Officers. Reports from the Extension Officers are co-ordinated by the District Officer at Half Assini. Therefore in terms of extension, Half Assini exercises overall authority and jurisdiction over the whole district.

Findings

1. Half Assini occupies the most dominant position in the linkages of all the services selected owing to the fact that it is the district administrative headquarters and, therefore, has the most important Government Departments. It is linked by one of the main trunk roads servicing the district and enjoys a great level of accessibility. It is near Jaway Wharf, which is an entry and exit point to and from La Côte D’Ivoire.
2. The utilization of the services attract visitors who have to satisfy other diverse needs from their trips and thereby lead to concentration of other functions at Half Assini.

Aggregate / Optimum Accessibility
These are measures adopted to give a summary of the general accessibility situation in the district. Aggregate accessibility deals with surface accessibility to any one of the services under consideration.  Optimum accessibility on the other hand deals with accessibility to all services at a particular place at a time e.g. settlements or zones.

Functional Region Analysis
The functional region is the area where there is intense interaction or cohesion. The essence of mapping out this region is to give an indication of areas where initial investment could take place. In mapping this region the optimum accessibility situation in the district was heavily relied on.

In the Jomoro District, the functional region is located around Half-Assini and Elubo. These zones have most of the population, as well as the socio-economic activities of the district hence there are intense interaction and cohesion in these two communities.
