Sustainable food production in West Africa is increasingly challenged by declining soil fertility, erratic rainfall, and demographic pressures that intensify demand for land. In this context, farmers often respond to stagnating yields by expanding cultivated areas, a strategy that accelerates the conversion of fallows and natural habitats into cropland. This study investigates whether agroecology informed sustainable intensification (SI) packages can improve technical land use efficiency and thereby reduce the incentive for agricultural expansion. The analysis focuses on smallholder maize systems across Northern Ghana, where land degradation and climate variability pose persistent constraints. Using farm level survey data from 372 maize producers across the Northern, Upper East, and Upper West regions, we estimate technical land use efficiency with a translog stochastic frontier model that treats land as a fixed input. This methodological choice provides a direct interpretation of efficiency as the effective land required to produce observed output. The SI package examined includes improved seed, more balanced fertilizer applications, and agroecological practices such as residue retention and intercropping. A matched comparison group of non adopters allows us to isolate adoption effects. The results show that SI adopters are, on average, 21% more land efficient than non participants, implying that approximately 24% less land would be needed to produce the same quantity of maize. Efficiency improvements are most pronounced among farmers initially furthest from the production frontier, indicating substantial equity gains when targeting less efficient producers. The analysis further highlights the importance of enabling conditions: education, advisory services, and access to credit all significantly enhance the likelihood and effectiveness of adoption. These findings strengthen the argument for agroecological transition pathways that bundle technological, institutional, and financial interventions. Such integrated approaches can raise productivity, limit pressure on land expansion, and contribute to land degradation neutrality and climate resilience in the savanna agroecosystems of West Africa.

This cross-country study examineed perceptions of maintenance for coated wooden cladding in residential buildings across Norway, Sweden, and Germany. As timber cladding gains popularity in European homes, understanding expectations around cleaning, recoating, and replacement intervals becomes increasingly important. An online survey gathered responses from over 3,000 participants aged 18–89, randomly selected from representative regional panels in each country. The survey focused on the perception of maintenance practices and intervals, while also collecting data on personality traits, risk aversion, and socioeconomic background. Perceived maintenance practices for coated timber cladding differed across countries, but individual characteristics were generally more influential than national context. Most respondents accepted longer cleaning intervals than recommended, while their preferences more closely aligned with guidelines for recoating. Acceptance of replacement intervals varied markedly by country. Longer acceptable maintenance intervals were associated with a higher preference for uncoated cladding, particularly in Germany and Sweden. Younger age, urban residence, limited experience, and selected demographic and personality traits were linked to more intensive maintenance preferences.

Boken gir en bred innføring i organisering og finansiering av helsetjenester, med vekt på norske forhold. Den innledende bolken omfatter kapitler om helsetjenestesystemer og forsikringsordninger, betalingssystemer og demografiske endringer. I de følgende bolkene brukes de grunnleggende begrepene til å beskrive og analysere kommunehelsetjenesten og spesialisthelsetjenesten, samt samhandlingen mellom de to nivåene. Enkelte policy-orienterte temaer, som effektivitet og likhet i tilbudet, analyseres i egne kapitler. Den avsluttende bolken er viet komparativ helsepolitikk, med beskrivelser av land med sosialforsikringsordninger og private helseforsikringer. Utviklingen av EUs helsepolitikk beskrives i et eget kapittel. Bokens underliggende perspektiv er at organisering og finansiering er virkemidler i offentlig helsepolitikk. Dette er instrumenter som kan brukes til å redusere ulikhet i tjenestetilbudet, øke effektiviteten og heve kvaliteten. Boken inneholder oppdatert kunnskap om reformer og piloter fra de siste tiårene, også reformer i andre land som har relevans for norske forhold.
