Land use and land cover classification using phenological variability from MODIS vegetation in the Upper Pangani River Basin, eastern Africa por Kiptala, J.K., Mohamed, Y., Mul, Marloes L., Cheema, Muhammad Jehanzeb Masud, Zaag, P. van der

“…These fluxes are a function of land use and land management and as such an essential component for integrated water resources management. Spatially distributed land use and land cover (LULC) maps distinguishing not only natural land cover but also management practices such as irrigation are therefore essential for comprehensive water management analysis in a river basin. …”

Mapping Agroforestry and Trees Outside Forest por Rizvi, R.H., Handa, A.K., Sridhar, K.B., Kumar, A., Bhaskar, S., Chaudhari, S.K., Arunachalam, A., Thomas, N., Ashutosh, S., Sapra, R.K., Pujar, G., Singh, R.K., Londhe, S., Nayak, D., Dogra, A., Choudhary, R., Dhyani, S.K., Rizvi, J., Vågen, Tor-Gunnar, Ahmad, M., Prabhu, R., Biradar, Chandrashekhar M., Dongre, G.

“…In recent years, there has been a shift in the focus of agroforestry research from the plot or field scale to the landscape scale, which has uncovered the multiple benefits that trees provide in agricultural landscapes. But the spatial distribution and extent of agroforestry was not well understood earlier due to the complexity involved in accurately mapping agroforestry and Trees Outside Forest (TOF) in mixed tree/crop/ livestock systems. …”
