Integrating urban agriculture and forestry into climate change action plans: Lessons from Western Province, Sri Lanka and Rosario, Argentina
The document examines how integrating urban and peri-urban agriculture and forestry (UPAF) into city planning can address climate change risks, food insecurity, and urban poverty. In Western Province, Sri Lanka, the focus is on rehabilitating abandoned paddy lands to reduce flood risks and intensifying home gardening to lower GHG emissions and improve nutrition. In Rosario, Argentina, the city is using UPAF to mitigate the urban heat island effect, reduce 'food miles' and associated CO2 emissions, and manage storm water run-off. The report argues that subnational (provincial) government involvement is essential for scaling these interventions and integrating them into broader land-use and climate action plans.

Agricultural Water Management Technology Expansion and Impact on Crop Yields in Northern Burkina Faso (1980-2010): A Review
The study finds that soil and water conservation (SWC) and small reservoir expansion increased significantly in northern Burkina Faso, particularly in regions receiving 700 mm of rainfall or less. While regional cereal yields rose by approximately 3% per year, and rice productivity showed a strong correlation with reservoir expansion, the causal links to poverty reduction and food security are less clear due to data limitations. The report suggests that AWM adoption is one of many factors contributing to livelihood improvements and requires further long-term analysis to establish definitive causality.

Rural poverty and Food insecurity mapping at district level for improved agricultural water management in the Limpopo River Basin
The study maps rural poverty and food insecurity at the district level across Botswana, Mozambique, South Africa, and Zimbabwe from 2003 to 2013. It finds that while CPWF-LBDC research sites are generally located in poor areas, they are not always in the poorest districts. The report emphasizes that female- and child-headed households are the most vulnerable across all four countries and argues that poverty indices should be a primary factor in selecting sites for AWM interventions to effectively reduce food insecurity and poverty.

Climate-smart agriculture for food security in Africa
The document argues that African agriculture must transition to 'climate-smart' models to combat projected yield losses of up to 50% by 2020. Using Kenya as a case study, it highlights several low-cost innovations: greenhouse agriculture combined with drip irrigation to reduce water use; rainwater harvesting from rock outcrops; the adoption of drought-resistant cassava varieties; the use of alternative indigenous fodders like acacia pods and tubers for livestock; and the implementation of Plastic Tubular Digester (PTD) biogas technology to reduce deforestation and energy costs. The briefing emphasizes that scaling these innovations requires moving beyond pilot projects through 'bankable projects' that attract microfinance, promoting participatory action research via National Agricultural Research Systems (NARS), and leveraging farmers' groups for capacity building.

Agricultural water management in smallholder farming systems: the value of soft components in mesoscale interventions
The report argues that successful mesoscale agricultural water management (AWM) depends heavily on 'soft components' such as initial social capital, participatory methodologies, and capacity building. Through meta-analyses and case studies in regions like India, Kenya, and Ethiopia, the authors find that participatory projects generally outperform top-down technocratic approaches. However, the report highlights a critical gap in the systematic monitoring and economic valuation of these social and environmental gains, noting that conventional cost-benefit analyses often ignore externalities and changes in natural and social capital.

NORTH CENTRAL ARIZONA WATER DEMAND STUDY Phase I Report
The North Central Arizona Water Demand Study (Phase I) assesses water demand and supply for 15 non-reservation communities on the Coconino Plateau. In 2000, total demand was approximately 5,842 million gallons, with potable water accounting for 80% and reclaimed wastewater for 16%. The report highlights a significant reliance on groundwater, often from deep and costly wells, and the critical role of wastewater reclamation in communities like Tusayan, where it meets 40% of demand. It identifies a wide disparity in conservation efforts, with Flagstaff having the most extensive program and Page lacking a serious initiative. The document concludes by proposing a Phase II forecasting methodology that uses population projections and water-use models to create baseline, moderate, and aggressive conservation scenarios.

RE-EVALUATING STORMWATER
The report presents a model for urban watershed restoration in the Pittsburgh region, specifically focusing on the 6.5 square mile Nine Mile Run watershed. It argues for 'restorative redevelopment,' which embeds the removal of stormwater from sewer systems into the incremental process of urban renewal. By using 'green infrastructure'—such as bioretention areas, porous pavements, and cisterns—the model aims to reduce combined sewer overflows (CSOs) and sanitary sewer overflows (SSOs) while providing community benefits like beautification and recreational amenities. The report details four sample designs (Hunter Park, Edgewood Crossroads, Sterrett School, and Regent Square Gateway) that meet specific hydrologic and budget criteria, and recommends the establishment of a permanent coordinating body to manage the watershed across municipal boundaries.
