Wider Area Sectoral Proposals
Introduction
The previous sections have considered and proposed climate resilient infrastructure projects which either directly support the proposed value chain opportunities, or further enable the town to respond to immediate needs with regards improvements in traffic and pedestrian circulation, public realm, solid waste management and extensions to the sewage and sanitation network.
This section outlines other proposed infrastructure projects which will assist with issues which are located in the wider hinterland of the town and will promote climate resilient approaches to the introduction of power, irrigation, water and the development of a recycling and waste treatment stream to service the town and it’s wider communities.
Most of these wider area sectoral proposals are aimed at increasing agricultural productivity and climate resilience as well as bringing wider economic opportunities to marginalised communities across the municipal area.

Case Study: Devergy is an energy services company that provides minigrids solutions to low income people in rural villages. In Mbeya, in western Tanzania, they installed an adaptive direct current solar PV minigrids to serve around 60 households. Customers can pre-pay for affordable energy services in daily, weekly or monthly package at local stored, or via mobile money services such as M-Pesa.
Devergy covers the installation costs except for a small connection fee of between US$6 (KSh 620) and 12, which covers wiring, metering and two bulbs. Customers can also purchase a range of energy efficient DC appliances, including LED lights, TVs, refrigerators and fans. In comparison a traditional grid connection could cost around US$250 (KSh 26,000). Devergy has initially relied upon financial assistance from USAid and other investors, Unlike traditional government minigrids projects, this one is market driven with key innovations around the scalable technology, payment system and operating model. Additionally Devergy maintains a long-term commitment to the village, so they are available to ensure system operation and reliability are maintained. Devergy’s work has demonstrated that minigrids can be both profitable for the operator and affordable for the customer16 .

Case Study: Grid Alternatives International Program has been helping farmers in Nicaragua with sustainable irrigation solutions for the last five years. One such solution helped the Valle family of Matagalpa. They grew squash, passion fruit and tomatoes on two acres of land to sell at the local market but had trouble making a profit due to high irrigation costs. The monthly electricity bill to run their pump was US$33, but their income was only US$103. Also, the supply quality was poor, meaning they could only irrigate on three days per week instead of every day. Other expenditure reduced their earnings to US$25 a month. Working with Grid Alternatives and local company Suni Solar, they installed a solar irrigation system. The total cost was US$10,000, but Valle family was only asked to pay US$2,000 which they financed via UNAG, their national agricultural organisation. Two solar panels power a pump that abstracts water from a nearby river into a cement tank and to a gravity fed pole mount system that drips onto the plants. With adequate water supply to the plants, they can now irrigate other crops, including onions, pipian and pasturage, and also raise tilapia. Their monthly electricity bill is now US$3, and their monthly earnings have now increased to US$54618 .
WATER MANAGEMENT Sustainable Irrigation
Agriculture is a key sector in Kitui, particularly in rural areas where it is estimated to contribute to around 87% of income. Reliance on agriculture make the population vulerable to water scarcity. Water and infrastructure for irrigation can help populations to become more resilient to changes in weather, it can increase land productivity abd enable the population to grow a more diverse and valuable crops. Sustainable irrigation practices provide a long-term solution for the management of spatially and temporally changing and increasing scarce water resources. Sustainable irrigation practises can be applied to all irrigation related activities to improve food security and achieve higher economical return while limiting the impact the environment. The sustainable irrigation helps to build resilience to droughts, floods, climate change, competition and pollution. Sustainability can be achieved through technical and nontechnical solutions. Technical solution includes selection of right crops and varieties, applying water saving technologies such as drip and sprinkler, greenhouse, hydroponics and automation. Non-technical solutions play equally important role supporting the long-term operation and maintenance of technical solutions. Thus, sustainability must be ensured by appropriate institutional strengthening and capacity building.

Case Study: Adopted from Malabo Montpellier Panel Report on Water-wise: Smart irrigation strategies for Africa Drip irrigation can improve agricultural yield by up to 100% over conventional irrigation system using 50% less irrigation water. An example from Ghana showed income growth of over 100 percent resulting from use of drip irrigation on onion fields. Since 1996, the Kenya Agricultural and Livestock Research Organisation (KALRO) has promoted gravity-fed drip irrigation systems to farmers who were previously watering their crops by hand. Depending on the crop, farmers reported additional income of between KSh 600 - 750,000 with a single bucket kit per person. In 2016, Kenya’s Meru University of Science and Technology developed a “sensor-based automatic irrigation system” app that monitors the need for water in fields and controls irrigation equipment. The app makes use of sensors placed in a field to determine the soil’s moisture. If it is too dry, a control unit uses solar panels to open the valve of a water tank and closes it again when the soil is damp enough. The upfront costs are high - KSh 50,000 per 0.1 ha for a combined app and irrigation system, including solar panels and two drip irrigation lines. The system can be expanded to an additional 0.1 ha for KSh 5,000. The US company SunCulture, based in Nairobi, has been selling solar irrigation kits to Kenyan smallholder farmers since 2013. The SunCulture AgroSolar irrigation system combines the energy efficiency of solar power with the effectiveness of drip irrigation. Solar panels provide the pump’s electricity without the need for batteries or inverters. Water is pumped into a raised water storage tank during the day. During the evening, the irrigation takes place and a valve on the water tank is opened; using gravity, water flows down through a filtration system onto the crop root zones via the irrigation tape. The kit costs KSh 260,000, including the solar pumping system, drip irrigation equipment for 0.4 ha, and training on how to operate the system. According to experience, farmers can increase their yields by up to 300 percent and save over KSh 1million per year compared to using petrol or furrow systems.

Case Study: Developing an Integrated Waste Management System15 - Kampala, Uganda In Kampala, Uganda, the development of an integrated waste system was prompted by the lack of formalisation in the waste sector. Much of the waste was disposed informally by dumping, burning or burying. Only 55% of the city’s solid waste was officially collected and transported to the city’s landfill by the Kampala Capital City Authority (KCCA). Several standalone Community Based Organisations (CBO) existed offering financial incentives to informal settlements for the collection of recyclable materials, however, the KCCA were not aware of many of these organisations. The KCCA developed a new Kampala City Integrated Waste Management System to improve the collection, transportation and treatment of the city’s waste and incorporate the informal sector (predominately the landfill pickers and CBOs) as part of an integrated approach across the waste management value chain.
As a result of the Integrated Waste Management System, a strategy was developed to identify, inform and consult stakeholders; clear objectives and measurable targets for education and knowledge sharing were created; activities were undertaken to educate waste pickers; a new contract was developed to ensure that new landfill operators would formally integrate registered waste pickers; and CBOs were encouraged to form partnerships with the KCCA in order make the System more integrated.
