The publication of the third edition of the WHO Guidelines for Drinkingwater Quality (WHO, 2004) introduced the concept of integrated, preventive risk management through water safety plans (WSPs) as a means to put into operation the principles, standards, norms and best practice proposed by the Guidelines. The WHO suggests applying the same concept to support the implementation and operationalization of their Guidelines for the Safe Use of Wastewater, Excreta and Greywater in Agriculture and Aquaculture (WHO, 2006) which follow the same principles of HACCP and health-based targets.

Swidden farming is the main agent of conversion of primary forests to secondary forests in the highlands of mainland Southeast Asia, but there is a deterioration and decline of the practice with land use intensification. The population growth in northern Thailand has forced lowland farmers practising permanent wet rice cultivation to turn to short rotation swidden in the foot hill zone. Highland swidden agriculturists are adopting more intensive forms of swidden or are shifting to permanent farming.

Measurements of nutrient stocks and greenhouse gas (GHG) fluxes are typically collected at very local scales (<1 to 30 m2) and then extrapolated to estimate impacts at larger spatial extents (farms, landscapes, or even countries). Translating point measurements to higher levels of aggregation is called scaling. Scaling fundamentally involves conversion of data through integration or interpolation and/or simplifying or nesting models. Model and data manipulation techniques to scale estimates are referred to as scaling methods.

Composite agricultural systems with permanent maize cultivation in the uplands and irrigated rice in the valleys are very common in mountainous southeast Asia. The soil loss and fertility decline of the upland fields is well documented, but little is known about reallocation of these sediments within the landscape. In this study, a turbidity-based linear mixed model was used to quantify sediment inputs, from surface reservoir irrigation water and from direct overland flow, into a paddy area of 13 ha. Simultaneously, the sediment load exported from the rice fields was determined.

This report summarizes the proceedings of the workshop “Scaling Up Climate
Services for Farmers in Africa and South Asia,” held in Saly, Senegal on December
10-12, 2012. The workshop brought together more than 100 experts from 30 countries
and roughly 50 institutions to grapple with the challenge of supporting vulnerable
farming communities through the production, communication, delivery and evaluation
of effective agrometeorological information and advisory services; and to identify
practical actions to address those challenges at scale.

In Nepal, more than 90% of cereal seed flows from informal systems and there are regions and groups of farmers that are not connected at all to any seed networks with external seed supply. Nepal's agricultural policies and formal institutions are promoting the development of the formal seed system. However, knowledge gaps exist on the opportunities and challenges for smallholder farmers when formal seed systems are becoming accessible.

This report presents lessons learned from 18 case studies across Africa and South Asia that have developed and delivered weather and climate information and related advisory services for smallholder farmers. The case studies and resulting lessons provide insights on what will be needed to build effective national systems for the production, delivery, communication and evaluation of operational climate services for smallholder farmers across the developing world.

This report explores evidence and insights from five case studies that have made significant recent progress in addressing the challenge of insuring poor smallholder farmers and pastoralists in the developing world. In India, national index insurance programmes have reached over 30 million farmers through a mandatory link with agricultural credit and strong government support. In East Africa (Kenya, Rwanda and Tanzania), the Agriculture and Climate Risk Enterprise (ACRE) has recently scaled to reach nearly 200,000 farmers, bundling index insurance with agricultural credit and farm inputs.

Engagement platforms are variously known as multi-stakeholder platforms or innovation platforms. In general terms, an engagement platform is an opportunity for individuals and people representing organizations with different backgrounds and interests to come together to diagnose problems, identify opportunities and implement solutions. They may engage in design and implementation as a platform, in smaller groups, or individually.

This manual has been developed to help build the capacities of farmers, farmers groups, extension staff and project managers who are implementing agricultural carbon projects in Eastern Africa. The manual describes the steps for implementing an afforestation/reforestation voluntary carbon project based on the Plan Vivo Standard.
