Sewage sludge: a review of business models for resource recovery and reuse
In many low- and middle-income countries, sewage sludge generated from wastewater treatment systems has potential environmental and health hazards. To tackle this challenge, there is a need for innovative options given the increasing concerns and policies restricting sewage sludge dumping in landfills and elsewhere, and a growing awareness about the resource value of sludge within a circular economy. In developed countries, water utilities, municipalities and the private sector are increasingly engaged in utilizing and innovating modern resource recovery technologies to capture biosolids, nutrients or energy from sewage sludge and reducing disposal.; This study reviews existing approaches and business models for resource recovery and moves the discussion beyond technical feasibility. Case studies were analyzed in support of four main sets of business models depending on the targeted resource: (i) organic fertilizers, (ii) crop nutrients, (iii) energy, and (iv) organic fertilizers and nutrients along with energy. The extraction of organic fertilizers through dewatering, thickening, stabilization or long-term storage drives the first set of models followed by technological advances in phosphorus recovery. The business models on energy similarly start from conventional energy recovery processes (anaerobic digestion) and move toward incineration. The discussion covers recent advances in gasification and pyrolysis. Transforming sewage sludge into biochar, for example, can support soil fertility and carbon sequestration. The final set covers integrative approaches supporting soil fertility and energy needs.; The critical step for emerging economies is to develop a wastewater management strategy and link it to a circular economy framework without having a negative impact on environmental and human health. While technologies and business models generally have a favorable policy environment, there is a lack of a regulatory framework that allows the marketing, use and export of recovered (waste-derived) resources for certain applications. For example, there needs to be an increase in industry acceptance of phosphorus recovered from sewage sludge to penetrate agricultural markets despite the currently still cheaper phosphate rock, which is a finite resource.

Assessment of farmers’ willingness to pay for bundled climate insurance solutions in Sri Lanka
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 fr 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 farmersapos; 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 farmersapos; 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.

Afghanistan Drought Early Warning Decision Support (AF-DEWS) Tool
This report summarizes the development of the Afghanistan Drought Early Warning Decision Support (AF-DEWS) Tool, a cloud-based online platform with near real-time information on drought conditions, to provide decision-makers with maps and data to enable further analysis. The report provides an overview of how the AF-DEWS Tool was developed and how it can be used to systematically monitor, detect and forecast drought conditions in Afghanistan. The tool provides a wide range of indicators/indices to assess the severity of meteorological (rainfall anomaly, standardized precipitation index), hydrological (snow cover index, streamflow drought index, surface water supply index), and agricultural (vegetation health index, integrated drought severity index) droughts.; The authors evaluated historical drought events, specifically the widespread drought event of 2018, to identify the precise impact of drought that has affected more than 13 million people across 22 of the 34 provinces in the severe to extreme drought category. Key drought indices were selected to undertake a detailed evaluation of the major drought events and their impacts on crop production. Satellite-derived (Moderate Resolution Imaging Spectroradiometer [MODIS]) Gross Primary Productivity (GPP) data and observed wheat production data provided by the National Statistics and Information Authority (NSIA) were used. This demonstrates the capabilities of the AF-DEWS Tool in supporting drought early warning and informing preparedness and risk reduction measures.

Scaling farmer-led irrigation requires strengthening human capacity and knowledge exchange among all actors and stakeholders involved. IWMI takes an action research approach, working with national and international research institutions, governments, extension agents and public and private organizations to co-develop the scaling ecosystem and strengthen capacity to drive scaling networks and collective action. We support the
A lack of affordable credit, particularly for women and resource-poor farmers, is one of the main barriers to expanding farmer-led irrigation in low- and middle-income countries. But
The ability of farmers to engage in or expand irrigation depends on the prevailing socioeconomic, ecological and political contexts, which are often complex, non-linear and changeable. Overcoming systemic barriers to farmer-led irrigation development while taking advantage of existing opportunities
Population pressure and increasing water competition in a changing climate require us to take stock of the availability and use of water across scales. Water availability not only influences farmers’ commercial prospects but also irrigation-related enterprises and agri-businesses. Greater water scarcity could jeopardize irrigation and agricultural markets while excessive water use can lead to declining ecosystems, water quality and soil health. IWMI advises development partners and the public and private sectors on all aspects of water resource availability and use through a variety of advanced modeling and remote-sensing products and tools, including
