In Africa, where most agriculture is rainfed, crop growth is limited by water availability. Rainfall variability during a growing season generally translates into variability in crop production. While the seasonality of rainfall in the drier rangelands can play a significant role in productivity, rain-use efficiency (RUE)—the amount of biomass produced (in kilograms of dry matter per hectare) per millimeter of rainfall—also drives production.

Rapid Assessment of Returns on Investments in Natural Resource Stewardship

Reports & Research
Novembre, 2014
Kenya

The report summarizes the findings of a participatory assessment of returns on investments in strengthening customary institutions for natural resource stewardship in four wards of Isiolo over the long dry season of 2014. Due to the rapid timeframe for the assessment, many observed benefits were not yet quantified. However, those that could be appraised so far already outweighed the investments made through the Isiolo Climate Adaptation Fund and by the members of the local institutions.

This paper presents the initial data analyses of the CCAFS gender survey implemented in four sites in Africa. Using descriptive statistics we show gender differences in terms of perceptions of climate change, awareness and adoption of climate smart agricultural (CSA) practices, and types and sources of agro-climatic information in the four sites.We find that both men and women are experiencing changes in long-run weather patterns and that they are changing their behaviours in response; albeit relatively minor shifts in existing agricultural practices.

The potential and uptake of remote sensing in insurance: A review

Journal Articles & Books
Novembre, 2014

Global insurance markets are vast and diverse, and may offer many opportunities for remote sensing. To date, however, few operational applications of remote sensing for insurance exist. Papers claiming potential application of remote sensing typically stress the technical possibilities, without considering its contribution to customer value for the insured or to the profitability of the insurance industry. Based on a systematic search of available literature, this review investigates the potential and actual support of remote sensing to the insurance industry.

Livestock: recyclers that promote the sustainability of smallholder farms

Journal Articles & Books
Octobre, 2014
Afrique

Livestock are kept for a wide range of purposes in Africa, and there is considerable diversity in animal husbandry. Among the most important advantages in keeping animals is their contribution to maintaining and even improving soil fertility. Furthermore, animal husbandry offers economic, social and cultural benefits. However, the authors also look at the constraints that smallholders face in livestock husbandry.
