This is the final report (2009-2011 June) of the RUAF-FSTT Programme for the South and South East Asia Region, coordinated by the International Water Management Institute (IWMI), from its Regional Office in Hyderabad, India. The programme of activities were carried out in two cities, namely Magadi, Ramanagara District, India, and Gampaha, Sri Lanka from 2009 to June 2011, with an no-cost extension of six months, ending in year June 2011. This programme of activities came under IWMI’s theme on Water quality, Health and Environment.The programme was aimed at strengthening farmer organisations and their marketing capacities in urban/periurban settings, and developing sustainable urban farming systems that will contribute towards poverty alleviation, empowerment of disadvantaged and underserved groups in cities, enhance urban food security and social inclusion in development. The core activities were planned around two major components; 1. Operationalisation of a City Strategy Agenda (CSA), through a city multistakeholder forum (MSF) to promote Urban/Periurban Agriculture (UPA), which included diverse UPA activities and supported the shaping of policies to sustain UPA activities; 2. An innovation project that targeted low-income urban producers to innovate their farming practices from a market chain perspective, promoting eco-intensive agriculture based on ecological principals and maximum use of natural resources.

Introduction: With the renewed drive towards malaria elimination, there is a need for improved surveillance tools. While time series analysis is an important tool for surveillance, prediction and for measuring interventions’ impact, approximations by commonly used Gaussian methods are prone to inaccuracies when case counts are low. Therefore, statistical methods appropriate for count data are required, especially during ‘‘consolidation’’ and ‘‘pre-elimination’’ phases.Methods: Generalized autoregressive moving average (GARMA) models were extended to generalized seasonal autoregressive integrated moving average (GSARIMA) models for parsimonious observation-driven modelling of non Gaussian, non stationary and/or seasonal time series of count data. The models were applied to monthly malaria case time series in a district in Sri Lanka, where malaria has decreased dramatically in recent years.Results: The malaria series showed long-term changes in the mean, unstable variance and seasonality. After fitting negativebinomial Bayesian models, both a GSARIMA and a GARIMA deterministic seasonality model were selected based on different criteria. Posterior predictive distributions indicated that negative-binomial models provided better predictions than Gaussian models, especially when counts were low. The G(S)ARIMA models were able to capture the autocorrelation in the series.Conclusions: G(S)ARIMA models may be particularly useful in the drive towards malaria elimination, since episode count series are often seasonal and non-stationary, especially when control is increased. Although building and fitting GSARIMA models is laborious, they may provide more realistic prediction distributions than do Gaussian methods and may be more suitable when counts are low.

Agricultural development towards security of food, nutrition and livelihood is high on the political agenda in Sri Lanka. Recently, national priorities have included the development of food-secure and resilient cities; in this regard, the Western Province has been a forerunner, having commenced its urban agriculture campaign as early as 2000.

The use of food waste (FW) from food services as animal feed through informal agreements has been in practice for many years in Sri Lanka. However, data to show the scale of this practice are inadequate. This paper aims to study the extent of FW diverted to piggeries and the opportunities and challenges in reusing FW as animal feed. The data were collected via telephonic survey from 24 piggery farmers in the Western Province in May 2020. Results revealed that 50% of farmers were rearing 100-300 pigs. Farmers used FW as a major feed source to satisfy 82% of total feed requirement on an average. About 40% of the farmers collected the FW from multiple sources such as hotels, restaurants and canteens. Given that the piggery farms are located in peri-urban areas, the average distance traveled by the farmers is 38 km up and down which indicated the value of FW for them. FW was supplied mostly free of charge; however, 26% of the farmers pay LKR 2 to 40/kg when supplied by intermediaries. FW was collected daily, and the amount collected by the farmers varies 50 to 10000 kg/day depending on demand and supply, with 75% of farmers collected less than 1000 kg/day.

Sustainable management of municipal solid waste (MSW) is a critical issue around the world, especially in South Asia where waste generation is expected to double by 2050. Closing the food-nutrient cycle through composting biodegradable MSW has the potential to meet human needs, including sanitation and food security, while protecting the environment. We use an interdisciplinary case study approach including systems thinking to assess Sri Lanka’s national MSW composting system, which primarily receives residential and commercial food waste. We embed quantitative compost quality analysis and interviews at 20 composting facilities within a broader qualitative assessment informed by ~60 stakeholders in total. This approach yields insights on how institutional, economic, social, and biophysical aspects of the system are interrelated, and how challenges and solutions can create undesirable and desirable cascading effects, respectively. Such dynamics can create risks of composting facility failure and unintended consequences, diminishing the chances of achieving a sustainable circular food–nutrient system. Compost quality, which was variable, plays a pivotal role within the system—a function of program design and implementation, as well as a determinant of value capture in a circular economy. We make several recommendations to inform future efforts to sustainably manage biodegradable MSW using composting, drawing on our case study of Sri Lanka and prior case studies from other nations. Key among these is the need for increased emphasis on compost product quality and markets in policy and program design and implementation. Targeted measures are needed to improve waste separation, boost compost quality, effectively use compost standards, encourage compost market development, ringfence the revenues generated at municipal compost plants, and identify efficient modes of compost distribution. Such measures require adequate space and infrastructure for composting, resource investment, local expertise to guide effective system management, strong links with the agriculture sector, and continued political support.

Using farm animals for their natural capability of “recycling” food waste (FW) that is unfit for direct human consumption can support a circular economy as shown in the case of Sri Lanka’s Western Province. The reuse of organic residues including FW as animal feed is a traditional agricultural practice in Sri Lanka but is less studied within an urban FW context. A survey of piggeries using FW in and around the rapidly urbanizing city of Colombo showed that FW is a major feed source in the farms accounting for on average 82% of total feed. About 40% of the farms collected the FW mainly from hotels, restaurants, and institutional canteens. Urban FW is supplied to farmers free of charge when collected directly from the sources, although 26% of the farmers collected FW via intermediaries against a fee. As FW is collected daily, the restaurants appreciate the reliable service, the farmers the low-cost feed, and the municipality the reduced FW volumes to be collected. However, this triple-win situation encounters challenges such as (tourist related) seasonal low supply, which was exacerbated under the Covid-19 lockdown of food services. Another area of concern refers to biosafety. Although the large majority of interviewed farmers boil FW which contains raw meat or fish, there is a paucity of related guidelines and control. Given the benefits of FW use, it is worthwhile to explore how far these informal partnerships could be scaled without increasing transport costs for farmers, while introducing biosafety monitoring. For now, the regulatory environment is highly siloed and does not support material transitions across sector boundaries towards a circular economy.

With the increasing frequency and intensity of climate-related disasters, several social protection and livelihood resilience tools have been tested to reduce agricultural risks. The findings of this study are based on the initial bundled climate insurance solutions pilot conducted in five districts in Sri Lanka (Anuradhapura, Vavuniya, Monaragala, Kurunegala and Ampara) in 2021 with the support of Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ). The project intervention was designed to reduce production risks and enhance agricultural resilience through the roll-out of an index insurance product bundled with hybrid seeds and mobile-based weather and agronomic advisories. The research assessed farmers' willingness to pay (WTP) for weather index insurance (WII) solutions with bundled choices as a risk transfer tool with due consideration to the diversity and heterogeneity of the farming population. The report informs the scaling opportunities of bundled climate insurance choices, including product design and implementation among smallholder farmers and reduction of production risks in designing and implementing WII products. The study findings confirm the majority of farmers' perceptions of high climate risk, but the degree of risk is variable between areas and different segments of people. Farmers’ age, gender, farming experience, levels of education, land size operated, and household income form the major factors characterizing the diversity and risk exposures. Attention to gender and social equity issues is important in the design and delivery of insurance products so that the benefits of the interventions reach most of the farming population; this can ensure achievement of the larger development objectives of equity and fairness to disadvantaged people including women. Farmers are experiencing high or very high levels of variability in crop yield, input prices and output prices. However, the differences in willingness to experiment with innovations to minimize the risks and adopt risk-taking approaches to minimize production risks and strengthen livelihood resilience indicate the requirement for carefully designed insurance products. Awareness creation is a prerequisite for this intervention to be a sustainable one. About 80% of farmers are willing to enroll in crop insurance programs, but a major inhibiting factor is the lack of trust in insurers. The amount that farmers are willing to pay as an insurance premium is in the range of 1-2% of the sum insured for the majority of farmers. Bundling insurance with farm support services could be the primary strategy for transitioning insurance programs to be a financially viable and sustainable adaptation strategy, and for upscaling these programs.
