This paper analyzes the adoption behavior of smallholder farmers using comparable plot-level duration data for Kenya and The Philippines. We find that adoption behavior is strongly linked to the process of land ownership transfer. This relationship is found both for data from Kenya and The Philippines and is robust to the inclusion of observed and unobserved village, household, plot, and time factors.
La pandémie de Covid-19 est sans aucun doute l’événement majeur de santé publique qui a marqué les êtres humains, les sociétés et les esprits dans le monde entier et particulièrement l’Afrique. Tous les gouvernements ont adopté des mesures de santé publique, notamment le confinement et d’autres mesures exceptionnelles dans le cadre de l’état d’urgence sanitaire, pour réduire la propagation du virus. La chute soudaine de l’activité humaine a des conséquences sur l’environnement, et l’utilisation/exploitation des ressources naturelles, notamment la pêche.
Agriculture influences and shapes the world’s ecosystems, but not always in a positive way. More than 2.5 billion people are globally involved as stewards of land and water ecosystems that constitute the natural resource base for feeding the current and future world population. Yet, conventional agronomic interventions based on ‘hard’ agricultural engineering compromise various eco-services that are required for sustainable agricultural development.
Few regions present bigger development challenges than the African drylands – home to nearly 300 million people, and the vast majority of Africa’s poor. Food security and rural welfare in these areas are limited by a range of factors, biophysical, socio-economic and policy-related. And many of the biggest challenges – poverty, drought, land degradation, food insecurity – will be exacerbated by climate change.
Preliminary findings on the effects of land use in the Masinga Dam catchment, Kenya, on the storage capacity of the reservoir are presented. Remote sensing and GIS techniques, supplemented with ground reports, were used to determine areas most susceptible to erosion. A representative catchment was then chosen for rainy season monitoring of soil loss, river suspended sediments and discharge response to rainfall. In addition, Gerlach-type traps were used to evaluate erosion rates under different crop covers and slope gradients.
In the Tana River Basin in Kenya, six Regional Circulation Models (RCMs) simulating two Representative Concentration Pathways (RCPs) (i.e., 4.5 and 8.5) were used as input to the Soil and Water Assessment Tool (SWAT) model to determine the possible implications for the hydrology and water resources of the basin. Four hydrological characteristics – water yield, groundwater recharge, base flow and flow regulation – were determined and mapped throughout the basin for three 30-year time periods: 2020–2049, 2040–2069 and 2070–2099. Results were compared with a baseline period, 1983–2011.

There are many options for enhancing food production from fish in managed aquatic systems.The most appropriate technology, however, will vary from place to place, and the conditions under which one technology is prefered over another are still not well defined.
In recent decades, many countries in sub-Saharan Africa have pursued national water permit systems, derived from the colonial era and reinforced by “global best practice.” These systems have proved logistically impossible to manage and have worsened inequality in water access. A new study conducted by the International Water Management Institute (IWMI) and Pegasys Institute, with support from the UK government, traces the origins of these systems, and describes their implementation and consequences for rural smallholders in five countries – Kenya, Malawi, South Africa, Uganda and Zimbabwe.
