Participatory approaches within development programs involving common-pool resources are intended to revive a community’s role in managing these resources. Certainly, to ensure the successful and equitable use of such resources, community participation is essential. However, in many cases, attempts at applying a participatory approach often fail to...

Abstract (en) In spite of the 30% increase in the food supply since 1961, significant changes are anticipated over the coming decades that will increase the challenges facing smallholders. Climate change, rapidly growing population and increasing pollution all add to the risks of water and food security. This is happening at a time when water resou...

Over the past century, rising demand for food, feed, and fiber has been met largely by expanding the use of water, soils, and land. Projected increases in demand for agricultural output and resource use may well outstrip our avail- able water, land, and soil resources if production practices continue to follow the trodden pathways. Even though at p...

Increases in global food production are needed to eradicate hunger and secure food for a growing world population. Recent studies suggest that global food production will need to increase by nearly 50% by 2050. Meeting these food production requirements will rely in large part on the world’s smallholder producers. These farmers manage nearly 500 mi...

There is an ongoing debate on what constitutes sustainable intensification of agriculture (SIA). In this paper, we propose that a paradigm for sustainable intensification can be defined and translated into an operational framework for agricultural development. We argue that this paradigm must now be defined-at all scales-in the context of rapidly r...

The two cultures theory argues that policy makers and scientists have different cultures and difficulty in communicating with each other. Others argue that there is increasing co-production of knowledge. This essay aims to assess the concerns of policy makers based on our policy work, policy-related research work, and our day-to-day experiences in...

The term “nexus” implies equivalence among its component parts, which can be misleading when applied to the water-food-energy-climate debate as water is more than just one component; it is central to every aspect of the problem. Water is the only element that cuts across social, ecological and economic sectors, and is the only medium through which...

The ‘water box’ dilemma must be resolved. Leaders in the water sector – in water supply and sanitation, hydropower, irrigation and ood control – have long been aware that water is essential to sustainable development, but they do not make the decisions on development objectives and the allocation of human and nancial resources to meet them. These d...
