Ghana is confronted with waste management challenges. with 20-40% uncollected solid waste in most cities. Also. large volumes of faecal sludge are discharged untreated into the environment. Although these wastes pose serious environmental concerns, they also contain nutrients and organic matter essential for improving soil agricultural productivity. The International Water Management Institute (IWMI), since 2001. has researched into nutrient and organic matter recovery from faecal sludge and organic solid waste in Ghana and some Asian countries such as India, Sri Lanka or Bangladesh. This has led to the production of various formulations of faecal sludge based compost (with "Fortifer" as a generic 'brand '), both in the form ofpellets and powders, and specifically an ongoing project aiming at producing and commercializing the Fortifer in Ghana through a Public Private Partnership. This paper presents a summary of Fortifer technology, project objectives as well as lessons learnt during its implementation.

Improving on-farm water management by introducing wetting front detectors to small scale irrigators in Ethiopia [Abstract only] Paper presented at the Annual Tropical and Subtropical Agricultural and Natural Resource Management (Tropentag) Conference on Solidarity in a Competing World - Fair Use of Resources, Vienna, Austria, 18-21 September 2016. 1p.

Smallholder irrigation to improve food security in the dry season as well as economic and demographic growth within Ethiopia is developing rapidly. However, the long term sustainability of increased irrigated production, together with degradation of soils (and associated water bodies) may be irreparably damaged by inappropriate watering schedules. In irrigation schemes, over-irrigation results in periodic water scarcity issues and in some cases sodicity. The aim of the study was to evaluate whether using wetting front detectors (WFD), a simple mechanical irrigation advice tool, would give farmers the right knowledge on when and how much to irrigate. Therefore, improving sustainable on-farm water management without negatively affecting crop and water productivity while fostering a more equitable water distribution within the scheme. The study, conducted in different regions of Ethiopia, covered various agro-ecological zones and soil conditions with over 200 farmers irrigating cereals or vegetables. Farmers and water user associations were trained on using the WFD to irrigate and distribute water within the scheme. Irrigation and crop performance was evaluated against control plots, having the same crop variety and management but traditional irrigation practices. Reduction in applied irrigation volume due to the WFD differed within and between sites due to furrow length, soil texture and farmer experience. Although yield increases were highly variable between farmers due to differences in farm management and crop variety cultivated, there was a positive effect of WFD on water productivity. Water productivity on average increased by 9 % whereas yields for the different crops increased between 13 and 17 %. In some cases the volume of water saved could double the cropped area. The reduction of irrigation events, when using the WFD, led to labour saving (up to 11 working days per ha) and fuel saving (between 50 and 150 US$ per ha). In both sites, farmers positively evaluated the scheduling tool, acknowledging that they learned to save water without negatively impacting crop productivity. The study showed that by providing access to when and how much to irrigate, farmers can positively adjust their on-farm water management resulting in more sustainable usage of their natural resources.

In low- and middle-income countries, the management of fecal sludge from on-site sanitation systems has received little attention over many decades, resulting in insufficient or missing regulations to guide investments and management options. To address this gap, this report examines existing and emerging guidelines and regulations for fecal sludge management (FSM) along the sanitation service chain (user interface, containment, emptying, transport, treatment, valorization, reuse or disposal). It also draws empirical examples from guidelines across the globe to support policy-makers, planners, and sanitation and health officers, as well as consultants in low- and middle-income countries in the development and design of local and national FSM guidelines and regulations.
