The document examines the use of Bhungroo, an innovative rainwater harvesting system, to support underprivileged female farmers in Gujarat, India. By providing women with ownership of the technology and the technical skills to manage it, the initiative has improved agricultural productivity, reduced groundwater salinity, and increased women's decision-making power and social status. The project has reached over 20,000 marginal farmers and contributed to the reverse migration of approximately 6,100 farmers back to rural areas.

The project proposes a USD 45 million intervention to restore 50,648 hectares of degraded land and support land-based enterprises in four Kenyan counties. It aims to reduce greenhouse gas emissions by approximately 7.1 million tCO2eq and benefit 57,250 direct beneficiaries through climate-smart agriculture, reforestation, and the creation of 25,000 green jobs. The initiative focuses on three main components: enhancing climate-smart land practices, transforming rural livelihoods via green enterprises, and improving policy and climate information systems.

The interim evaluation of the GCF project FP007 in the Maldives finds the project generally on track, with a 'moderately satisfactory' rating for its overall objective. The project aims to provide safe freshwater to 105,000 people by scaling up integrated water supply systems (rainwater, groundwater, and desalination). While infrastructure construction for rainwater harvesting (RWH) and integrated water resource management (IWRM) systems is advancing, the evaluation notes that targets for groundwater recharge and consumption are unrealistic for the project's timeframe. Initial implementation was hampered by political transitions and procurement delays, but financial delivery improved significantly in 2019. Sustainability is rated as 'moderately likely,' contingent on the government's commitment to operation and maintenance (O&M) budgets and the ability of utilities to recover costs.

The Malekula Water Supply Project aims to transition water infrastructure on Malekula Island from vulnerable decentralised systems to climate-resilient centralised systems. The project addresses freshwater scarcity caused by sea-level rise, saltwater intrusion, and erratic rainfall. Key interventions include relocating boreholes inland to avoid salinity, installing new extraction and treatment systems from the Malua and Losinwei rivers, and implementing ecosystem-based adaptation (EbA) through the restoration of indigenous forests to improve groundwater recharge and reduce erosion. The project also establishes emergency water supply protocols and consumption-based tariffs to ensure long-term operational sustainability.

The briefing identifies that agriculture accounts for 70 percent of annual freshwater withdrawals and proposes five interventions: reducing food loss and waste, shifting diets toward less water-intensive foods, investing in nature-based solutions like agroforestry, optimizing crop placement and water management, and adopting efficient technologies such as drip irrigation.

The project aims to support approximately 380,500 direct beneficiaries in the Kigoma region of Tanzania, focusing on Nduta, Mtendeli, and Nyarugusu refugee camps and surrounding host communities. It addresses risks including rising temperatures, erratic rainfall, and increased flooding, which threaten subsistence agriculture and ecosystem services. The proposed interventions include participatory climate-resilient land use planning, community-based forest management, agroforestry, and the promotion of climate-resilient agricultural practices and diversified livelihoods such as beekeeping and mushroom cultivation. The project will be executed by UNHCR and overseen by UNEP, with a total indicative cost of USD 31,985,328, requesting USD 18,835,253 from the Green Climate Fund.

The Climate-Resilient Cities in Latin America Initiative (CRC) focused on small and medium-sized cities (50,000 to 1 million inhabitants) to bridge the gap between research and concrete climate action. The initiative emphasizes that while these cities are highly vulnerable to hydro-meteorological disasters, they offer significant opportunities for resilience due to their proximity scale. Key strategies included the co-generation of knowledge using both scientific data and citizen perceptions, the implementation of low-cost technological prototypes, and the integration of a gender perspective to address the disproportionate impacts of climate change on women. The report argues for a localization agenda where resilience is integrated into local development plans and supported by greater fiscal and administrative decentralization.

The report identifies significant investment opportunities in South Africa's urban water sector across four markets: commercial and industrial, residential, new property developments, and municipalities. It highlights a projected 17% gap between water supply and demand by 2030, with severe shortages expected in Gauteng, Mpumalanga, KwaZulu-Natal, and the Western Cape. In the Berg River management area, this deficit could cost the region over R146 billion and 650,000 jobs per year by 2040. Key opportunities include water-efficient technologies, wastewater reuse, desalination, and non-revenue water reduction. The report also details the regulatory environment, including the National Water Act and municipal by-laws, and emphasizes the Western Cape's role as a greentech hub.

The report analyzes the systemic gender inequalities in Bangladesh and how they exacerbate women's vulnerability to climate change, specifically salinity intrusion in coastal regions. It proposes a gender-transformative project to provide safe drinking water via Rain Water Harvesting and support climate-resilient livelihoods, such as crab farming and homestead gardening, while addressing structural barriers like land tenure and social norms.

The document argues that investing in water resilience makes financial sense regardless of whether water tariffs are strict or relaxed. It models three business scenarios—a medium-sized office, a medium-sized manufacturing facility, and a large manufacturing facility—demonstrating that solutions like smart metering, retrofitting, and rainwater harvesting can reduce municipal water reliance by up to 70% and lower water-related costs by 60%. All modelled solutions are projected to pay for themselves in under six years.

Quality Beverages reduced its water use by 27% and waste water production by 61% between 2016 and 2017. This was achieved through a staff educational campaign with consumption targets and the implementation of a system to collect, filter, and reuse waste water from bottle rinsing processes. The company reported monthly water savings of 3,000 kilolitres and cumulative savings of R870,000 up to January 2018, with a total capital investment of R140,000. Future plans include augmenting water supply via rainwater and groundwater to reduce reliance on municipal sources.

The document advises Cape Town residents to assume untreated water from boreholes, rain tanks, and springs is unsafe due to microbes and chemicals. It recommends testing water against the SANS 241 standard and suggests boiling as the simplest microbial treatment. It also provides a comparison of various household treatment methods and guidelines for sterile storage using food-grade plastics.

The report highlights a critical need for water resilience in the Western Cape due to severe drought and climate change. It identifies four primary investment areas: water metering and monitoring, water efficiency, water reuse, and alternative water supplies (groundwater, rainwater, and desalination). The document details market potentials, such as a R2 billion potential market for potable water reuse in Cape Town and a R5.8 billion potential residential market for alternative water systems in the Western Cape. It also outlines significant barriers, including municipal creditworthiness, high capital costs, and public perception of wastewater reuse.

It addresses the high vulnerability of the island's small-scale, rain-fed agriculture to extreme weather, including hurricanes, droughts, and sea-level rise. The plan outlines 45 adaptation measures organized under four major outcomes: enhancing the enabling environment, improving nutrition and food security, strengthening partnerships, and building adaptive capacity to climate extremes. The document includes 11 project concept notes to attract international and national funding for initiatives such as biological pesticide production, climate-resilient livestock centers, and agro-meteorological mobile applications.

The Water SASAP 2018-2028 provides a comprehensive adaptation strategy for Saint Lucia to safeguard its water resources against climate change. It identifies critical vulnerabilities, including a 35% water supply deficit and 42% non-revenue water loss, alongside projections of increasing temperatures and decreasing precipitation. The plan outlines 70 measures grouped under four outcomes: enhancing the enabling environment, increasing water access and quality, improving water efficiency, and strengthening preparedness for extremes. It includes 19 detailed project concept notes ranging from wastewater master planning to the digitisation of hydro-meteorological data, with implementation led by the Water Resources Management Agency (WRMA).

The report highlights a significant market for green water technologies in South Africa, driven by resource scarcity, rising costs, and climate change. Key opportunities include industrial water reuse, smart water management, desalination, and groundwater development. In the Western Cape, the industrial water reuse market is estimated at R600 million, while the direct potable municipal reuse market is valued at R4.5 billion. The document also emphasizes the water-energy nexus and the need to reduce municipal non-revenue water, which currently stands at 37% nationally.

The Maldives is implementing a GCF-funded project starting on Sh. Funadhoo and expanding to 48 other islands to combat water scarcity caused by altered monsoon patterns and tsunami contamination. The project focuses on rainwater collection, groundwater quality, and distribution networks to reduce reliance on expensive desalination. This initiative is part of a broader national adaptation plan including zoning and erosion control, while highlighting the gap between current GCF funding and the global climate finance mandate.

The report highlights the Western Cape's status as a water-stressed region where demand is projected to surpass supply by 2019 in the Western Cape Water Supply System (WCWSS). It identifies diverse business opportunities in the green economy, including precision irrigation, desalination, water reclamation, and the reduction of non-revenue water. The document details the institutional structure of South African water management and outlines specific funding incentives and grants available for greentech manufacturers and infrastructure projects.

The paper presents TAGMI, an online open-access tool using Bayesian network models to assess the likelihood of success for agricultural water management (AWM) interventions at a sub-national level. By integrating social, human, physical, financial, and natural factors, the tool evaluates the potential for outscaling three specific technologies—soil water conservation/in situ rainwater harvesting, small-scale private irrigation, and small reservoirs for communal irrigation—within the Limpopo and Volta river basins. The authors use a climate change scenario to test the robustness of these interventions and argue for the further development of Decision Support Systems and the identification of implementation best practices for poverty-constrained smallholder systems.
