Forest commons, vertical integration and smallholder’s saving and investment responses: Evidence from a quasi-experiment

Dambala Gelo
As the result of prohibitively high transaction costs, smallholder farmers are only partly integrated into agricultural and forest commodity markets, a situation that may leave them in a lower level of development equilibrium (i.e., a poverty trap). For the most part, many users of forest commons...

The effects of price and non-price policies on cigarette consumption in South Africa

Ernest Ngeh Tingum, Alfred Kechia Mukong and Noreen Mdege

Does the choice of balance-measure matter under Genetic Matching?

Adeola Oyenubi and Martin Wittenberg
In applied studies, the influence of balance measures on the performance of matching estimators is often taken for granted. This paper considers the performance of different balance measures that have been used in the literature when balance is being optimized. We also propose the use of the...

Determinants of Successful Collective Management of Forest Resources: Evidence from Kenyan Community Forest Associations

Boscow Okumu and Edwin Muchapondwa
Participation of local communities in management and utilization of forest resources through collective action has become widely accepted as a possible solution to failure of centralized top down approaches to forest conservation. Developing countries have thus resorted to devolution of forest...

Economic Valuation of Forest Ecosystem Services in Kenya: Implication for Design of PES Schemes and Participatory Forest Management

Boscow Okumu and Edwin Muchapondwa
Forest ecosystem services are critical for human well-being as well as functioning and growth of economies. However, despite the growing demand for these services, they are hardly given due consideration in public policy formulation. The values attached to these services by local communities are...

Farm diversification and climate change: implications for food security in Northern Namibia

Chalmers Mulwa and Martine Visser
Limited non-farm opportunities in the rural areas of the developing world, coupled with population growth, means agriculture will continue to play a dominant role as a source of livelihood in these areas. Thus, while rural transformation has dominated recent literature as a way of improving welfare...
