Biogas in Vietnam is chiefly the story of the success of small domestic digesters. However, a feed-in tariff for electricity generated by biogas plants could soon lead to larger scale use of the technology, and so provide new sources of income for farmers.

Aquaculture holds a big potential to satisfy the growing demand for aquatic food. Setting out from lessons learnt in past development projects, our author describes what fish farming systems must look like to fit the needs of smallholders and the environment.

In a long-term project in Kenya, the Swiss-based Research Institute of Organic Agriculture has examined the potential of organic and conventional agriculture regarding soil fertility, the occurrence of pests and diseases, and profitability. Initial results make a strong case to implement policy measures necessary for supporting the adoption of organic management practices on a large scale.

An ingenious combination of plant breeding, contract farming and processing has enabled smallholder tomato growers to tap new markets in Tanzania’s Arusha Region. Two improved tomato cultivars released from AVRDC lines are at the centre of this success story.

A project run by the WWF has set itself the goal of transforming Philippine tuna fisheries towards more sustainable practices, securing the livelihoods of the small-scale fishers in the long term. European buyers who have committed to source from them provide the necessary incentives.

A project in Burkina Faso has given a clear demonstration of what supporting family farms can achieve in terms of poverty alleviation and rural development. One important success factor was the transfer of land to farmers, accompanied by a secure land-tenure policy adapted to their needs.

Rural extension services are an extremely complex affair. This is due to the wide range of constellations in which farmers operate nowadays, and also to the large number of players who are active in advisory services, with their different tasks, values and mandates. With reference to Germany’s rural extension services, our author shows who is taking on which role and where conflicts might potentially arise.

Often with just one or two ponds managed by a single person or family, smallholders make up an important share of the world’s seafood production. So why are by far the minority of certified aquaculture operations smallholders?

Snakebites are a crucial, yet underreported issue in many South Asian countries. In India, they kill some 50,000 people every year. However, the government has neglected the issue. Now, it’s time to seriously address this all but forgotten public health problem, our author maintains.

Providing extension and advisory services is expensive. There are salaries to be paid, transporta­tion and operational funds to be provided, buildings to be rented or built, demonstration plots to maintain, and continued education to be offered to the extension staff. And then there is the need to continually invest in an overall functioning agricultural innovation system with strong research and teaching institutions, enabling policies, as well as to make capital investments in rural infrastructure that will not only benefit the farming population.

Sailing out to sea in the morning and returning without a catch in the evening is now a thing of the past for many Indian fishermen. A satellite-based information system shows where they can find rich fishing grounds.

The sustainable management of soils is crucial to achieving the Sustainable Development Goals. This is evidenced by the analysis of the role soils play across the proposed agenda. However, some key aspects have not been sufficiently considered so far. Moreover, the SDGs will place increased demand on soils. Further advocacy is therefore needed to ensure that important soil and land related issues remain in the final declaration of the post-2015 agenda.
